（2022·全国·高三）Do you know 5G It is the fifth generation of mobile network technology. These new networks are coming.
China just issued commercial licenses for 5G on June 6, 2019. This means that China’s telecom companies will be able to offer 5G networks for mobile phone users.
Each mobile network generation is faster and more powerful than the one before it. 1G let us talk to each other. 2G let us send messages. 3G gave us data and the Internet. And 4G made all of these things faster. What’s special about 5G
5G has a very short delay between sending and receiving information. Now, 4G takes about 100 to 200 milliseconds to send and receive data. But 5G will get it down to 1 millisecond or less-this is almost real-time.
This big change will not only make our mobile Internet faster, but also deeply change our lives. Read on to find out how.
5G + entertainment
5G networks are about 100 times faster than 4G. This means you can download a movie in seconds using 5G.
Also, virtual reality(VR) games will become more popular with 5G. The short delay of 5G will make the games feel even more real.
5G + transport
5G will also bring us safer self-driving cars. These cars can send signals to each other. They also talk to traffic lights and road sensors. 5G will allow cars to react even faster than human drivers.
5G + smart homes
5G also makes the Internet of things possible. Internet of things is a large network that connects everything to the Internet. Smart homes are part of it.
For example, your toaster can automatically start making breakfast after your alarm rings. And if its sensor feels the air becoming dry, a smart sprinkler could water your plants by itself.
12．What’s the writer’s purpose in writing the third paragraph
A．To explain 5G is the best of all.
B．To share his knowledge about 5G.
C．To encourage people to use the new network technology.
D．To show the development of mobile network technology.
13．What does the underlined word “delay” in paragraph 4 mean in Chinese
A．卡顿 B．延时
C．暂停 D．掉线
14．Which of the following ways is not mentioned that 5G will change people’s lives

（2022·湖北·高二期末）China will have the most 5G connections of any nation by 2025, according to a new study, while Europe will fall behind Korea, the United States and Japan in terms of 5G penetration (渗透) by that year.
5G is the fifth generation of network technology. It is expected to bring unbelievable speeds to Internet users, with some operations running 10 times faster than on 4G networks. 5G is also expected to unlock the potential in a lot of new services, including artificial intelligence, science of robots self-driving cars, and the Internet of things.
The GSMA said that China’s three major mobile operators—China Unicorn, China Mobile, and China Telecom—are already moving ahead with 5G networks. While most nations will have 5G by updating existing foundations, the study noted that China plans to build part of its 5G networks.
One of the most distinguishing factors between Chinese mobile operators and those in the rest of the world is the intention to erect the new and independent 5G networks. That is, China is determined to build a completely advanced 5G. The high cost underlines China’s seriousness about paying whatever it takes.
Korea will lead the world in terms of 5G penetration in 2025, when 66 percent of the nation’s total connections will be 5G, according to GSMA．This compares to 50 percent in the US, 49 percent in Japan, 36 percent in China, 30 percent in Europe, and a global average of 18 percent. Out of the five economies leading on 5G, Europe will have the lowest participation in 2025, as the area is moving more slowly in having its 5G networks.
16．What will 5G bring
A．A completely new pattern for daily life.
B．Excellent networks and national safety.
C．Amazing speeds for public transportation.
D．Realizing the potential of artificial intelligence.
17．What is the future of 5G in China
A．It will develop rapidly. B．It may lack financial support.
C．It will move forward slowly. D．It may fall behind Europe.
18．Which of the following best explains “erect” underlined in paragraph 4
A．bring up B．set up C．take up D．pick up
19．What can we infer from the last paragraph
A．Koreans cannot connect 5G in 2025. B．Some Chinese will have access to 5G in 2025.
C．Only five countries will have 5G in 2025. D．Europe will pay little attention to 5G in 2025.

（2022·江西抚州·高三期末）We have heard some interesting ways that 5G wireless technology might change our lives in the future. 5G technology promises the internet speeds between 50 to 100 times faster than 4G systems. Despite used in some limited areas of America this year, 5G is not widely used until 2023.
One project in Britain, however, is already testing this super-fast technology on an unlikely group Internet users—cows. The project was developed by American technology company Cisco Systems, Inc. It also receives money from the British government. Cisco says the program wants to enlarge the future of 5G in countryside areas around the world.
Testing areas were set up at farms in 3 countryside areas of England. The cows are equipped with 5G devices (装置) that connect to a robotic milking (挤奶) system, which uses sensors (传感器) and machine learning to fully automate the process. System designers say technology takes over after a cow feels ready to be milked and walks towards an automatic gate. During the milking, machines give food for the cow as a reward.
Other technology tools powering the 5G smart farms include automated brushes that turn on when the cow rubs up (蹭) against them. Sensors also control the amount of light to the cows living areas depending on the weather. And, an automatic feeding system makes sure the animals always have enough to eat.
Duncan Forbes, head of a government-funded agricultural engineering organization, told Reuters that the project shows the farm’s cow operation can be greatly improved with 5G technology and that the experiment provided strong evidence that 5G technology can be widely used in the future, not just on farms in Britain, but in countryside across the world.
20．Why does Cisco Systems Inc develop the project
A．To win economic support from the British government.
B．To enlarge the future use of 5G technology in countryside.
C．To improve the development of 5G technology in Britain.
D．To test the effects of 5G technology on animals.
21．What does the underlined word “automate” in paragraph 4 refer to
A．robotize B．complete C．remove D．fasten
22．The following technology tools are used in 5G smart farm EXCEPT ________
A．automated brushes. B．sensors.
C．cleaning system. D．an automatic feeding system.
23．Which of the following can be the best title for the text
A．5G technology is applied to the milking process.
B．5G makes the management of animals easy and interesting.
C．5G technology will be popular in the future.
D．5G technology brings money to farming.

（2021·甘肃·民勤县第四中学高三期中）Your Internet experience is terrible when the net speed is too slow—it takes so long to open a web page and the film you’re watching stops every few minutes. That can be very annoying. But it could be a thing of the past. In the near future, major telecom carriers will start to provide 5G services.
What is 5G What difference will it really make to our lives The “G” in “5G” refers to the generations of mobile network technologies.
1G let us talk to each other, 2G let us send messages, 3G gave us mobile data and the Internet, and 4G made all of these things faster. Now 5G promises much faster data download and upload speeds, and more stable connections. This means that you will be able to download an entire HD movie in seconds and only experience a short delay between sending and receiving data. For example, when you have a video chat with your friend, there is generally a 200 milliseconds delay with 4G, but 5G will reduce the delay to 1 millisecond, which is almost real time.
5G will be able to improve many advanced technologies, such as driverless cars, wearable devices and entertainment. With a 5G network, the short delay in information exchange will allow driverless cars to run more safely, as they will be able to communicate in real time and avoid dangers. Meanwhile, 5G-enabled wearable devices will keep doctors updated on the health status of their patients, so doctors can give patients advice immediately if there’s something wrong. Besides, VR games will become more popular with 5G.The short delay of 5G will make the games feel even more real.
Though 5G will make our lives more convenient, it will not be perfect. For one thing, 5G will not “travel” far. On 4G networks, you can be 10 kilometres away from the nearest transmission base and barely lose signals. But 5G will only cover about 300 metres, meaning that we will need more transmitters so that we can get signals. And in order to use 5G, we will have to buy new products specifically designed for 5G that are currently expensive.
29．What does the “G” in “5G” refer to
A．Games. B．Groups. C．Grades. D．Generations.
30．What question does Paragraph 4 answer
A．How much does 5G cost in real time. B．Why will 5G reduce the delay.
C．How will 5G improve the driverless cars. D．What changes will 5G bring us
31．Which of the following is NOT true
A．3G gave us mobile data and the Internet.
B．5G will allow driverless cars to run more safely.
C．5G will cover about 300 metres to 1,000 metres.
D．5G will make the VR games feel even more real.
32．Where is the article possibly from
A．A diary. B．A magazine. C．A storybook. D．A novel.

（2022·辽宁丹东·二模）After circling Earth for six months, the three crew members of China’s Shenzhou XIII mission have departed from the Tiangong space station and returned to the mother planet on Saturday morning, finishing the nation’s longest manned spaceflight.
Zhai Zhigang, who was the mission commander, Wang Yaping and Ye Guangfu breathed fresh air for the first time after the half-year space journey as ground recovery staff opened the door of their reentry capsule (返回舱) at 10: 03 am.
Medical service workers on the site told China Central Television that the astronauts are in good condition. Carrying the mission crew, the Shenzhou XIII spacecraft left from the Tiangong station at 12: 44 am. In the last hours of their stay inside the Tiangong, the astronauts worked with ground controllers to adjust the station, sending some experimental data back to Earth and sorting out materials.
The crew has set a new record for China’s longest spaceflight, almost doubling the previous record of 92 days created by their colleagues in the Shenzhou XII mission who travelled with Tiangong from mid-June to mid-September last year.
During the Shenzhou XIII mission, the astronauts carried out two spacewalks that totaled more than 12 hours. They tested components on the station’s robotic arm and used it to practice spacewalk. Wang took part in the first spacewalk on Nov 7, becoming the first female Chinese spacewalker.
The crew members also carried out two science lectures from the space station for Chinese students. In one experiment, Wang used a Bing Dwen Dwen toy, the popular mascot (吉祥物) of the Beijing 2022 Olympic Winter Games, to display how objects fly in weightless environment. The space-based lessons marked the start of the Tiangong Class series, China’s first space lecture series that aims to popularize space science and inspire youngsters to pursue their “science and space dreams”, according to the manned space agency.
1．What mission did the crew members accomplish

（2022·四川·宜宾市教科所三模）SpaceX, a private company, has put 60 Starlink communication satellites into orbit, bringing the total circling Earth to 180. They will bring internet access to underserved areas of the world. But it seems they also mess with telescopes.
When the satellites pass through a telescope’s field of view, they create bright streaks(条痕) that cut through images of the sky, hiding anything that might be behind them and pouring so much light into the telescope that it causes some observations unusable.
“What surprised everyone - the astronomy community and SpaceX - was how bright the satellites are”, said anxiously space experts. Actually SpaceX did talk about the issue elsewhere. The problem for astronomers doesn’t end with SpaceX. Blue Origin, One Web and Amazon plan to launch thousands of communications satellites in the coming years.
In an effort to ease astronomers’ fears, SpaceX is testing one satellite that is a bit different from the others. It was included in the most recent launch and is partially coated in a dark material to make it less shiny and so less visible in telescope images. We don’t have any data yet on whether the coating is working as intended.
Once the satellites are in space, there is no backtracking. While companies like SpaceX do need approval from regulatory bodies(监察机构) for each launch, there is no rule that prevents them from launching an unlimited number of satellites.
“We have to rely on firms such as SpaceX voluntarily cooperating with astronomers to attempt to keep the impacts of their satellite constellations (卫星星座) as low as possible.” said space experts.
With more than 1,500 Starlink satellites scheduled for launch in the near future, that cooperation will need to be speedy if it is going to make any difference.
5．Why does SpaceX launch so many communication satellites
A．To expand internet services worldwide.
B．To make users surf the Internet quickly.
C．To disturb the operation of telescopes.
D．To further present space research.
6．What are space experts worried
A．Satellites are too shiny to be seen.
B．Satellites occupy the area of telescopes.
C．Too many satellites move in outer space.
D．The normal use of the telescopes is affected.
7．What can be inferred from the passage
A．The number of satellite launches will decrease.
B．Coated satellites can effectively weaken brightness.
C．The regulations of satellite launching are not powerful.
D．SpaceX’s cooperation with astronomers remains to be seen.
8．What is probably the best title for the passage
A．Troubles Made by Satellites
B．Satellites Threatening Astronomers
C．SpaceX and Its Future Starlink Plan
D．Cooperation with Astronomy Community

（2022·重庆市涪陵高级中学校模拟预测）Space travelers face a number of health risks. Astronauts have reported loss of bones and muscle and some even have developed immune disorders and heart problems. A new study finds that energy-producing new structures in cells might be to blame for many of these problems.
A systems biologist, Afshin Beheshti, who studies how different parts of the body work together, also a member of a team of researchers that want to know how spaceflight might affect cells and tissues, notes, “It’s a basic question.”
The team looked at NASA GeneLab’s collection of data from past space biology experiments and studied cells and tissues from mice and people and compared space travelers with others that had remained on Earth.
“The idea is not only to look at one type of chemical,”Beheshti says. Rather, they wanted to “look at the living system as a whole”. And in doing that, they found a common theme. After some time in space, mitochondria, the energy powerhouses of cells, often didn’t work as well as they should.
Those findings are consistent with samples from NASA’s Twin Study. Before retiring, astronaut Scott Kelly spent nearly a year aboard the International Space Station. His twin, Mark remained on the ground. Afterward, blood samples from the two showed different mitochondrial activities.
For the latest study, Beheshti and his team studied GeneLab data for many types of cells and tissues. Another focus was related to metabolism. That process includes a mix of chemical activities that supports life in cells, organs and the whole body.
Damage to mitochondria may be a common factor in spaceflight health risks, the team now concludes. Finding similar changes in so many astronauts indeed points to some general effect, agrees Michael Snyder, a systems biologist at Stanford University in California, who worked on Scott and Mark Kelly’s Twin Study but was not part of the new analysis. If mitochondria are the cause, dealing with problems of them could help protect future astronauts. Some diseases cause mitochondrial defects(线粒体缺陷). Dealing with such diseases in different ways may help reduce astronauts’ health risks. Future studies could test if existing drugs prevent mitochondrial problems in cells, animals and people on long deep-space travels.
9．What might cause astronauts to have health problems according to the new study
A．Temperature difference. B．Heart cell increase.
C．Cell problems. D．Tiring work.
10．Which method did Beheshti’s team employ to do the research
A．They did all kinds of tests on astronaut Scott Kelly.
B．They referred to some previous data.
C．They followed some astronauts for many years.
D．They observed behaviors of astronauts in person.
11．What may contribute to the decrease of astronauts’ health risks
A．Treating the diseases which cause mitochondrial defects.
B．Performing fewer long deep-space travels.
C．Letting new structure in cells grow quickly.
D．Making astronauts eat as healthily as possible.
12．What’s the main idea of the text
A．Astronauts face great danger in the space station.
B．Space travels are really dangerous to astronauts’ health.
C．Scientists have found ways to reduce astronauts’ health risks.
D．Space travels may harm health by damaging mitochondria.

（2022·河南·南阳中学三模）Humans have been exploring the infinite abyss (深渊) beyond Earth’s atmosphere. When astronauts explore the vast expanse of outer space, they need to wear high-tech spacesuits to protect them from the freezing conditions of the universe.
Hollywood movies have idealized the iconic suit, its design leading the masses to believe it’s an outfit that can be slipped on within minutes. In fact, the spacesuit which is made up of nearly a half dozen different components and can have up to 16 layers is its own fully functioning spacecraft that takes hours to put on and requires help from one’s colleagues.
The astronauts on the Artemis missions, NASA’s next program to send the first woman and the first person of color to the moon, will wear the latest spacesuit, called the exploration extravehicular mobility unit, also known as xEMU, according to NASA．
Each spacesuit has a portable life support system, which includes a water tank for the cooling garment and carbon dioxide removal system to regulate body temperature, remove excess heat and maintain the astronauts’ health, said Richard Rhodes, the deputy lead for xEMU pressure garment development at NASA．A two-way radio system is also included so the astronauts can communicate during the missions.
“When the Apollo astronauts walked on the moon, they couldn’t bend over and pick up a rock,” said NASA astronaut Mike Fincke. Fortunately, spacesuits have come a long way since then and have a more flexible structure with gloves. The gloves are one of the most complicated parts of the spacesuit, said Cathleen Lewis, curator of the Smithsonian Institution’s National Air and Space Museum. “Gloves are very difficult to design to be protective and also allow the manual dexterity (灵巧) that astronauts need to do meaningful work.” she noted.
The spacesuits will also be getting some upgrades for the latest lunar mission. Richard Rhodes’s team is working on the spacesuit that will allow for more movement to explore the rough terrain of the moon while still being strong enough to protect the wearer.
13．What can we learn about the spacesuit in Hollywood movies
A．It provides the most ideal design. B．It functions as a spacecraft of its own.
C．It can be put on without too much difficulty. D．It can protect the astronauts from the cold in space.
14．In what aspect does Paragraph 4 mainly talk about the latest spacesuit
A．Its operating methods. B．Its component parts.
C．Its existing problems. D．Its initial aims.
15．Why are the Apollo astronauts mentioned in the passage
A．To contrast the Apollo spacesuit with the latest one.
B．To give an example of a successful space mission.
C．To demonstrate the failure of the Apollo missions.
D．To criticize the incompetence of the Apollo astronauts.
16．Which of the following best describes NASA’s spacesuit for the next lunar mission
A．High-tech but impractical. B．Portable and mobile.
C．Costly but well-received. D．Flexible and protective.

（2022·青海·模拟预测）An experimental cleanup device called RemoveDebris has successfully cast a net around adummy (仿造的) satellite, simulating (模拟) a technique that could one day collect spaceborne garbage.
The test, which was carried out this week, is widely believed to be the first successful demonstration of space cleanup technology, experts told CNN. And it signals an early step toward dealing with what is already a key problem: rubbish in space.
Millions of pieces of junk are turning around in orbit, the result of 50 years of space travel and few regulations to keep space clean. At orbital speeds, even a small bit of paint crashing with a satellite can cause serious damage.
Various companies have plans to send thousands of new satellites into low-Earth orbit, already the most crowded area.
The RemoveDebris experiment is run by a company and researchers led by the UK’s Surrey Space Centre and includes Airbus, Airbus-owned Surrey Satellite Technology Ltd. and France’s Ariane Group.
Guglielmo Aglietti, the director of Surrey Space Centre, said that an operational version of the RemoveDebris technology would cast out a net that remains fastened to the main satellite so the debris can be dragged out of orbit. It could target large pieces of junk, including dead satellites up to 10meters long.
The RemoveDebris satellite will conduct a few more experiments in the coming months, including testing navigation systems that could help guide the satellite to a specific piece of debris. Jonathan McDowell, an astrophysicist at the Harvard Smithsonian Centre for Astrophysics, said the success of this week’s experiment was exciting, but he cautioned against “over-publicizing” it. There are still big barriers to clear before operational cleanup tasks will be underway, he said, and the biggest challenge is figuring out how to fund such projects.
Aglietti, the Surrey professor who helped lead the RemoveDebris project, said “the challenge will be to convince the relevant authorities to sponsor these tasks”. Aglietti said he hopes RemoveDebris will conduct a few cleanup tasks per year, targeting the largest pieces of rubbish in the most crowded orbits. Aglietti is hopeful.
17．What attracts people to invent RemoveDebris
A．Exploring space. B．Testing an orbit.
C．Cleaning satellites. D．Removing waste in space.
18．How does the RemoveDebris work
A．It throws a net to take junk from orbit. B．It fastens junk to the main satellite.
C．It targets large pieces of junk carefully. D．It drags junk up to 10 meters long.
19．What do we know about RemoveDebris
A．It is successful in cleanup tasks.
B．It still needs to be broadcasted widely.
C．It should get some financial help from authorities.
D．It helps researchers to find a specific junk.
20．What’s the best title of the text
A．Space Garbage Causes Severe Damage
B．Researchers Advertise Waste Collecting Satellite
C．Authorities Sponsor RemoveDebris Project
D．Satellite First Time Collects Waste

（2022·四川省泸县第四中学模拟预测）A satellite is about to demonstrate a new way of capturing space junk with magnets for the first time. With the frequency of space launches dramatically increasing in recent years, the potential for a disastrous collision above Earth is continually growing. Now, Japanese orbital clean-up company Astroscale is testing a potential solution.
The firm’s End-of-Life Services by Astroscale demonstration mission is scheduled to lift off on 20 March aboard a Russian Soyuz rocket. It consists of two spacecraft: a smaller “client” satellite and a larger “servicer” satellite, or “chaser”. The smaller satellite is equipped with a magnetic (磁力的) plate which allows the chaser to dock with it.
The two stacked spacecraft will perform three tests once in orbit, each of which will involve the servicer satellite releasing and then recapturing the client satellite. The first test will be the simplest, with the client satellite drifting a short distance away and then being recaptured. In the second test, the servicer satellite will set the client satellite tumbling before catching up with it and matching its motion to grab it.
Finally, if those two tests go well, the chaser will live up to its name by letting the client satellite float a few hundred metres away before finding it and attaching to it. All of these tests will be performed autonomously, with little to no human input once they are set in motion.
“These kinds of demonstrations have never been done before in space - they are very different to, say, an astronaut controlling a robotic arm on the International Space Station,” says Jason Forshaw at Astroscale UK. “This is more of an autonomous mission.” At the end of the tests, both spacecraft will burn up in Earth’s atmosphere.
If companies wanted to use this capability, they would have to attach a magnetic plate to their satellites so they could be captured later. Because of the growing space garbage problem, many countries now require firms to have a way to bring back their satellites once they run out of fuel or fail, so this could be a fairly simple likely plan, Forshaw says. Right now, each chaser can only nab one satellite, but Astroscale is working on a version that could drag three or four out of orbit at once.
21．Which of the following can replace the underlined word “dock with” in Paragraph 2
A．deal with B．keep up with C．join together D．crash
22．Why many countries now require firms to have a way to bring back their satellites
A．Because of the growing space waste problem.
B．Because the frequency of space launches are dramatically increasing.
C．Because they can earn large profits from it.
D．Because Astroscale has found a new method of capturing the space garbage.
23．What will Astroscale do to solve the space junk problem
A．An astronaut controls a robotic arm on the International Space to capture the “client” satellite
B．Through a magnetic plate remotely controlled by humans on the ground to catch the “client” satellite
C．Finding the “client” satellite and attaching to it with a magnetic plate automatically
D．Tumbling to match the motion of “client” satellite the drag three or four satellites out of its orbit into atmosphere.
24．What can we infer from the passage
A．people will burn the space junk up in Earth’s atmosphere in the future
B．Japan and Russia will conduct space debris cleanup experiment together
C．These kinds of demonstrations have never been done before.
D．the demonstration mission will be divided into three phases

（2022·湖南·长郡中学二模）China’s historic 23-day Chang’e 5 mission has not only obtained precious rock and soil samples from the moon, but has also brought back a group of seeds that traveled the furthest in the nation’s agricultural and forestry histories. More than 30 kinds of seeds were placed inside Chang’e 5 spacecraft and orbited around the moon for about 15 days.
Scientists wished to check what would happen to the seeds after being exposed to extraterrestrial(地外的)forces in lunar orbit and also hoped they could develop beneficial mutations (突变). This mission offered good opportunities to scientists, which enabled them to deepen their studies on the effect of cosmic rays on the growth and evolution of life on Earth.
Space-based mutation breeding refers to the process of exposing seeds to forces such as micro gravity, vacuums and cosmic radiation during a spaceflight and then sending them back to Earth for further observation and planting. Researchers observe and examine several generations of plants grown from space-bred seeds and investigate their mutations—some are positive and desirable while others are negative. Those with positive mutations will be kept and analyzed, and will be introduced to farmers after their certification and approval.
Space breeding can generate mutations faster and more conveniently than ground-based experiments and can bring about some desirable traits that are otherwise hard to pared with natural or conventionally bred types of plants, space-developed versions with positive mutations usually feature higher nutritional content, greater annual yields, shorter growth periods and better resistance to diseases and insect pests.
China conducted its first space breeding experiment in 1987. Since then, hundreds of kinds of seeds and seedlings have traveled with dozens of Chinese spaceships. Space breeding has helped to produce more than 200 new types of mutated plants in China that have been approved for large-scale cultivation, ranging from grains to vegetables and fruits. The Chang’e 5 robotic mission returned 1,731 grams of lunar rock and soil to Earth, marking a historic accomplishment 44 years after the last lunar substances were taken back.
25．Why were the seeds placed inside Chang’e 5
A．To pick out the fittest for mutations.
B．To understand extraterrestrial forces.
C．To study the intensity of cosmic rays.
D．To expose them to a special environment.
26．What do we know about space-based mutation breeding
A．It is not a time-consuming process.
B．Mutations develop in a random way.
C．It often brings about desirable effects.
D．Approval will be granted to mutated plants.
27．What’s the author’s attitude toward space breeding
A．Skeptical. B．Cautious.
C．Objective. D．Appreciative.
28．What is the best title of the passage
A．Space-bred Seeds Offer Great Chances B．Chang’e 5 Returns with a Big Package
C．Plant Mutations Result in a Better Life D．Seeds from Space Mark a New History

（2022·湖北·荆州中学三模）A Spanish rice dish; secreto de cerdo with pisto—Ibérico Pork with tomatoes, onions, eggplant, and peppers; and chicken and mushroom paella, will be served aboard the International Space Station (ISS) throughout the next week.
That, at least, is what four of the eleven crew members aboard the ISS will be eating, after a SpaceX Falcon 9 rocket lifts off on April 8,2022 from Cape Canaveral, Florida, carrying the Crew Dragon spacecraft. The flight, sponsored by the Houston-based company Axiom Space and known as Ax-1, is commanded by Axiom vice president and former astronaut Michael López-Alegría. Also on board are three business owners and charitarians: American Larry Connor, Canadian Mark Pathy, and Israeli Eytan Stibbe—each of whom paid an estimated $55 million per seat for their 20-hour journey to the station and the eight days they will spend aboard.
Actually, they are not the first space tourists to the ISS—eleven in total over the past two decades; and all of them were adventurers who paid to fly aboard crewed by professional astronauts. AX-1 is the first fully private mission to the station—but not the last.
In a pre-launch press conference, Connor said, “We’ve spent anywhere from 750 to over 1,000 hours training. We’re going to do some 25 different experiments covering over 100 hours of research.” One such experiment will involve a brain headset that will conduct real-time electroencephalograms (EEGs) of the crew as they fly and experiments on in vitro stem cells.
There will also be time for a moving remembrance. Stibbe, the second Israeli to fly in space, once piloted military jets under the command of Ilan Ramon, the first Israeli astronaut, who died in the 2003 disintegration of the space shuttle Columbia. Several pages from Ramon’s diary survived the crash and Stibbe will carry them into the space.
Space is a hard business, a dangerous business, and an expensive business. But it’s also an emotional one. “Ramon was a good friend,” Stibbe added respectfully, “He was my commander.”
29．Why does the author show the dishes at the beginning
A．To present the whole menu in the space mission.
B．To attract readers’ interest and introduce the topic.
C．To show the enjoyment of the crew members during the flight.
D．To highlight the wealth and social status of the crew members.
30．What’s the main purpose of the mission
A．To maintain the ISS. B．To provide space travel.
C．To help people settle in space. D．To send Spanish food to space.
31．How does Connor think about the mission before he flies
A．Fully-prepared and significant. B．Expensive but worthwhile.
C．Difficult and dangerous. D．Adventurous and challenging
32．Why does Stibbe want to bring Ramon’s diary into the space
A．Because he wants to continue writing the diary.
B．Because he can use Ramon’s diary as instructions.
C．Because he once piloted military jets under Ramon’s command.
D．Because he wants to show respect for Ramon in this way.

（2022·山东师范大学附中模拟预测）Astronomers breathed a sigh of relief as the James Webb Space Telescope(JWST)sprung to life. JWST would not fit into any modern rocket without being folded. However, ultimately the telescope has started returning some of its first images to thrilled audiences back on Earth.
Yet the experience left many astronomers wondering if there was a simpler way to launch telescopes of this size. “We were worried about the unfolding,” says John Blevins of NASA’s Marshall Space Flight Center. But with a larger rocket, “you don’t have to unfold in space. You can do it on the ground”.
As chance would have it, two such rockets are currently sitting on launchpads. The first, NASA’s Space Launch System(SLS), is ready and waiting at Kennedy Space Center in Florida for its voyage this summer. But a reliance on tried-and-true technology could be its Achilles’ heel: some estimates currently keep the SLS’s cost at an $4.1 billion per launch. If approved, though, its massive size could ultimately be a boon for scientists seeking to send larger, more ambitious spacecraft and telescopes throughout the solar system and even beyond.
Over in Texas, Starship, a similarly capable but wildly different rocket being developed by SpaceX, is also in preparation to launch on its first orbital test flight. Usually, each rocket will be deserted after a single use, its components degraded to junk on the seafloor or adrift in space. But Starship is instead built for endurance, landing back on the ground for rapid reuse, which has already dramatically lowered the expense of reaching space.
As big and bold as the SLS may be, experts say that it pales in comparison with what Starship could achieve. “Starship holds the promise of transforming the solar system in a way we can’t really appreciate,” says Alan Stern. “It completely changes the game.”
33．Why was it necessary to simplify the way to launch JWST
A．The size of some rockets was small. B．The launching technology was limited.
C．The unfolding of JWST was impossible. D．The cost of launching JWKT was costly.
34．What does the underlined word “boon” in Paragraph 3 probably mean
A．Benefit. B．Fantasy. C．Concern. D．Disaster.
35．What do we know about Starship in Paragraph 4
A．It will be recycled in space. B．It is not available for launching.
C．It will be abandoned after a single use. D．It has reduced the cost of reaching space.
36．What’s the experts’ attitude towards the future of Starship
A．Hopeful. B．Worried. C．Doubtful. D．Satisfied.

Riding a horse at a high speed on grassland covered with snow while dressed in a red cloak (披风) and a white fur hat isn't something people would normally see a Chinese government official do. So it's not surprising that He Jiaolong, a female official from Xinjiang Uygur Autonomous Region, almost instantly became an online celebrity after she posted such a video.
She came up with the idea to make the video when she was thinking about new ways to let more people know about the famous horse breed (品种) of Zhaosu County, Ili, known as “heavenly horses”.
“I never expected the video to be such a hit. At first, I really didn't like to be called an online celebrity, because l never wanted to be one. But now I'm gradually getting used to using my influence to boost local development, she said.
Besides posting short videos, she has also been promoting local agricultural products and tourist resources via livestreaming (直播). With more followers, she can now help to sell local products worth more than 2 million yuan during a livestream while sales were only about 5,000 yuan each time when she first started to livestream on social media.
While she continues to draw the public's attention to Ili, she also has to keep dealing with the stress brought by criticism, especially often being questioned if being a social media celebrity may affect her work as an official. She said that she had even thought of giving up appearing on social media several times.
“I am, above all, a government official. I will never let what I do on social media affect my job,” she said. “I want to see the locals appreciate my efforts in serving them, which is my duty. I hope people can feel the warmth and positive energy of Xinjiang officials via my videos. I am simply one of them.”

（2022·河北保定·高二期末）With the popularity of the Internet in recent years, major webcast platforms are in full swing, especially in this special period, many people are staying at home, crazy to engage in webcast. We should treat this problem in a dialectical way of thinking. Everything that is beneficial will have disadvantages. Today, with the rapid development of the Internet economy, “webcast” has become a means of information spreading. Today, with the popularity of webcast, we should comprehensively analyze its advantages and disadvantages.
“Webcast” has become a hot word, and even derived a series of new industries and new occupations, effectively promoting the development of social economy and the diversification of business forms. For example, in the stage of resumption of work and production after the epidemic was effectively controlled, the live broadcast of network anchors promoted the rapid growth of some regional economies to a certain extent. For example, CCTV invited live broadcast talents such as Li Jiaqi and Weiya to combine with stars to carry out live broadcast in Wuhan and other areas with serious epidemic, which effectively and rapidly promoted the economic development of Wuhan at that time. At the same time, educational live broadcasting can make up for the gap between education in backward areas and advanced areas to a certain extent, give children equal opportunities to learn, promote the national plan of educational equity, and let more children see the outside world.
But webcast also brings many problems. First, the quality of live broadcast goods is uneven. Many live broadcasters push and sell the goods in a template manner without detailed understanding. After customers receive the goods, the goods are not the right board. Because of logistics express fees and other reasons, they are also too lazy to argue, resulting in a gradual decline in public praise. Second, while bringing joy and economic growth, the live broadcast of online celebrity has made the social atmosphere more impetuous. The children’s ideal has become “I want to be an online celebrity”, thinking that there is food by one face. These dregs need to be abandoned. Third, the supervision of webcast is not strict, and vulgar information often appears, which brings bad social atmosphere.
To this end, we should first strengthen the supervision of webcast from the institutional level, especially the examination and approval of live broadcast content, standardize all live broadcast platforms, increase punishment, curb the bad live broadcast atmosphere from the source, and set up relevant vocational skills training according to the situation; Secondly, all broadcasters should effectively choose the live broadcast content, conform to the mainstream social value orientation, ensure the quality and level of live broadcast, and gradually get out of the mindset of echoing others; Finally, all public opinion media should create a positive and sunny attitude at the social level, treat the new thing of “live broadcasting” correctly, and guide public opinion to the right track.
10．What does the second paragraph say about webcast
A．Webcast can promote regional economic development and narrow the gap between urban and rural areas.
B．Webcast allows more children in cities to see the outside world.
C．The goods sold by webcast are of poor quality.
D．We should adhere to the correct guidance of public opinion when dealing with live broadcasting
11．What are the disadvantages of webcast mentioned in the article
A．Cause network congestion. B．Endanger national security.
C．Bring bad social atmosphere. D．Cause death of people.
12．What is the meaning of the underlined words in the third paragraph of the article
A．shabby B．common C．foolish D．silly
13．What is the purpose of the author’s writing the first paragraph
A．Challenge B．Attract reading interest C．Make a summary D．Come to the point

（2022·全国·高三）Do you know 5G It is the fifth generation of mobile network technology. These new networks are coming.
China just issued commercial licenses for 5G on June 6, 2019. This means that China’s telecom companies will be able to offer 5G networks for mobile phone users.
Each mobile network generation is faster and more powerful than the one before it. 1G let us talk to each other. 2G let us send messages. 3G gave us data and the Internet. And 4G made all of these things faster. What’s special about 5G
5G has a very short delay between sending and receiving information. Now, 4G takes about 100 to 200 milliseconds to send and receive data. But 5G will get it down to 1 millisecond or less-this is almost real-time.
This big change will not only make our mobile Internet faster, but also deeply change our lives. Read on to find out how.
5G + entertainment
5G networks are about 100 times faster than 4G. This means you can download a movie in seconds using 5G.
Also, virtual reality(VR) games will become more popular with 5G. The short delay of 5G will make the games feel even more real.
5G + transport
5G will also bring us safer self-driving cars. These cars can send signals to each other. They also talk to traffic lights and road sensors. 5G will allow cars to react even faster than human drivers.
5G + smart homes
5G also makes the Internet of things possible. Internet of things is a large network that connects everything to the Internet. Smart homes are part of it.
For example, your toaster can automatically start making breakfast after your alarm rings. And if its sensor feels the air becoming dry, a smart sprinkler could water your plants by itself.
12．What’s the writer’s purpose in writing the third paragraph
A．To explain 5G is the best of all.
B．To share his knowledge about 5G.
C．To encourage people to use the new network technology.
D．To show the development of mobile network technology.
13．What does the underlined word “delay” in paragraph 4 mean in Chinese
A．卡顿 B．延时
C．暂停 D．掉线
14．Which of the following ways is not mentioned that 5G will change people’s lives
A．Health care B．Entertainment.
C．Transport. D．Smart homes.
15．What’s the main idea of the passage
A．5G will change our lives in many ways.
B．Mobile networks are changing for better.
C．5G will make the Internet of things possible.
D．5G networks for mobile phone users are coming.

（2022·湖北·高二期末）China will have the most 5G connections of any nation by 2025, according to a new study, while Europe will fall behind Korea, the United States and Japan in terms of 5G penetration (渗透) by that year.
5G is the fifth generation of network technology. It is expected to bring unbelievable speeds to Internet users, with some operations running 10 times faster than on 4G networks. 5G is also expected to unlock the potential in a lot of new services, including artificial intelligence, science of robots self-driving cars, and the Internet of things.
The GSMA said that China’s three major mobile operators—China Unicorn, China Mobile, and China Telecom—are already moving ahead with 5G networks. While most nations will have 5G by updating existing foundations, the study noted that China plans to build part of its 5G networks.
One of the most distinguishing factors between Chinese mobile operators and those in the rest of the world is the intention to erect the new and independent 5G networks. That is, China is determined to build a completely advanced 5G. The high cost underlines China’s seriousness about paying whatever it takes.
Korea will lead the world in terms of 5G penetration in 2025, when 66 percent of the nation’s total connections will be 5G, according to GSMA．This compares to 50 percent in the US, 49 percent in Japan, 36 percent in China, 30 percent in Europe, and a global average of 18 percent. Out of the five economies leading on 5G, Europe will have the lowest participation in 2025, as the area is moving more slowly in having its 5G networks.
16．What will 5G bring
A．A completely new pattern for daily life.
B．Excellent networks and national safety.
C．Amazing speeds for public transportation.
D．Realizing the potential of artificial intelligence.
17．What is the future of 5G in China
A．It will develop rapidly. B．It may lack financial support.
C．It will move forward slowly. D．It may fall behind Europe.
18．Which of the following best explains “erect” underlined in paragraph 4
A．bring up B．set up C．take up D．pick up
19．What can we infer from the last paragraph
A．Koreans cannot connect 5G in 2025. B．Some Chinese will have access to 5G in 2025.
C．Only five countries will have 5G in 2025. D．Europe will pay little attention to 5G in 2025.

（2022·江西抚州·高三期末）We have heard some interesting ways that 5G wireless technology might change our lives in the future. 5G technology promises the internet speeds between 50 to 100 times faster than 4G systems. Despite used in some limited areas of America this year, 5G is not widely used until 2023.
One project in Britain, however, is already testing this super-fast technology on an unlikely group Internet users—cows. The project was developed by American technology company Cisco Systems, Inc. It also receives money from the British government. Cisco says the program wants to enlarge the future of 5G in countryside areas around the world.
Testing areas were set up at farms in 3 countryside areas of England. The cows are equipped with 5G devices (装置) that connect to a robotic milking (挤奶) system, which uses sensors (传感器) and machine learning to fully automate the process. System designers say technology takes over after a cow feels ready to be milked and walks towards an automatic gate. During the milking, machines give food for the cow as a reward.
Other technology tools powering the 5G smart farms include automated brushes that turn on when the cow rubs up (蹭) against them. Sensors also control the amount of light to the cows living areas depending on the weather. And, an automatic feeding system makes sure the animals always have enough to eat.
Duncan Forbes, head of a government-funded agricultural engineering organization, told Reuters that the project shows the farm’s cow operation can be greatly improved with 5G technology and that the experiment provided strong evidence that 5G technology can be widely used in the future, not just on farms in Britain, but in countryside across the world.
20．Why does Cisco Systems Inc develop the project
A．To win economic support from the British government.
B．To enlarge the future use of 5G technology in countryside.

（2021·江西·贵溪市实验中学高三阶段练习）Do you know 5G It is the fifth generation of mobile network technology. These new networks are coming.
China just issued commercial licenses for 5G on June 6, 2019. This means that China's telecom companies will be able to offer 5G networks for mobile phone users.
Each mobile network generation is faster and more powerful than the one before it. 1G let us talk to each other. 2G let us send messages. 3G gave us data and the Internet. And 4G made all of these things faster. What's special about 5G
5G has a very short delay between sending and receiving information. Now, 4G takes about 100 to 200 milliseconds to send and receive data. But 5G will get it down to 1 millisecond or less-this is almost real-time.
This big change will not only make our mobile Internet faster, but also deeply change our lives. Read on to find out how.
5G + entertainment
5G networks are about 100 times faster than 4G. This means you can download a movie in seconds using 5G.
Also, virtual reality(VR) games will become more popular with 5G. The short delay of 5G will make the games feel even more real.
5G + transport
5G will also bring us safer self-driving cars. These cars can send signals to each other. They also talk to traffic lights and road sensors. 5G will allow cars to react even faster than human drivers.
5G + smart homes
5G also makes the Internet of things possible. Internet of things is a large network that connects everything to the Internet. Smart homes are part of it.
For example, your toaster can automatically start making breakfast after your alarm rings. And if its sensor feels the air becoming dry, a smart sprinkler could water your plants by itself.
24．What's the writer's purpose in writing the third paragraph
A．To explain 5G is the best of all.
B．To share his knowledge about 5G.
C．To encourage people to use the new network technology.
D．To show the development of mobile network technology.
25．What does the underlined word “delay” in paragraph 4 mean in Chinese
A．卡顿 B．延时 C．暂停 D．掉线
26．Which of the following ways is not mentioned that 5G will change people's lives
A．Health care B．Entertainment. C．Transport. D．Smart homes.
27．What will people do possibly with 5G according to the passage
A．Download a movie in minutes. B．Put everything onto the Internet.
C．Make self-driving cars safer. D．Make food more easily and faster.
28．What's the main idea of the passage
A．5G will change our lives in many ways. B．Mobile networks are changing for better.

（2021·甘肃·民勤县第四中学高三期中）Your Internet experience is terrible when the net speed is too slow—it takes so long to open a web page and the film you’re watching stops every few minutes. That can be very annoying. But it could be a thing of the past. In the near future, major telecom carriers will start to provide 5G services.
What is 5G What difference will it really make to our lives The “G” in “5G” refers to the generations of mobile network technologies.
1G let us talk to each other, 2G let us send messages, 3G gave us mobile data and the Internet, and 4G made all of these things faster. Now 5G promises much faster data download and upload speeds, and more stable connections. This means that you will be able to download an entire HD movie in seconds and only experience a short delay between sending and receiving data. For example, when you have a video chat with your friend, there is generally a 200 milliseconds delay with 4G, but 5G will reduce the delay to 1 millisecond, which is almost real time.
5G will be able to improve many advanced technologies, such as driverless cars, wearable devices and entertainment. With a 5G network, the short delay in information exchange will allow driverless cars to run more safely, as they will be able to communicate in real time and avoid dangers. Meanwhile, 5G-enabled wearable devices will keep doctors updated on the health status of their patients, so doctors can give patients advice immediately if there’s something wrong. Besides, VR games will become more popular with 5G.The short delay of 5G will make the games feel even more real.
Though 5G will make our lives more convenient, it will not be perfect. For one thing, 5G will not “travel” far. On 4G networks, you can be 10 kilometres away from the nearest transmission base and barely lose signals. But 5G will only cover about 300 metres, meaning that we will need more transmitters so that we can get signals. And in order to use 5G, we will have to buy new products specifically designed for 5G that are currently expensive.
29．What does the “G” in “5G” refer to
A．Games. B．Groups. C．Grades. D．Generations.
30．What question does Paragraph 4 answer
A．How much does 5G cost in real time. B．Why will 5G reduce the delay.
C．How will 5G improve the driverless cars. D．What changes will 5G bring us
31．Which of the following is NOT true
A．3G gave us mobile data and the Internet.
B．5G will allow driverless cars to run more safely.
C．5G will cover about 300 metres to 1,000 metres.
D．5G will make the VR games feel even more real.
32．Where is the article possibly from
A．A diary. B．A magazine. C．A storybook. D．A novel.

（2022·辽宁丹东·二模）After circling Earth for six months, the three crew members of China’s Shenzhou XIII mission have departed from the Tiangong space station and returned to the mother planet on Saturday morning, finishing the nation’s longest manned spaceflight.
Zhai Zhigang, who was the mission commander, Wang Yaping and Ye Guangfu breathed fresh air for the first time after the half-year space journey as ground recovery staff opened the door of their reentry capsule (返回舱) at 10: 03 am.
Medical service workers on the site told China Central Television that the astronauts are in good condition. Carrying the mission crew, the Shenzhou XIII spacecraft left from the Tiangong station at 12: 44 am. In the last hours of their stay inside the Tiangong, the astronauts worked with ground controllers to adjust the station, sending some experimental data back to Earth and sorting out materials.
The crew has set a new record for China’s longest spaceflight, almost doubling the previous record of 92 days created by their colleagues in the Shenzhou XII mission who travelled with Tiangong from mid-June to mid-September last year.
During the Shenzhou XIII mission, the astronauts carried out two spacewalks that totaled more than 12 hours. They tested components on the station’s robotic arm and used it to practice spacewalk. Wang took part in the first spacewalk on Nov 7, becoming the first female Chinese spacewalker.
The crew members also carried out two science lectures from the space station for Chinese students. In one experiment, Wang used a Bing Dwen Dwen toy, the popular mascot (吉祥物) of the Beijing 2022 Olympic Winter Games, to display how objects fly in weightless environment. The space-based lessons marked the start of the Tiangong Class series, China’s first space lecture series that aims to popularize space science and inspire youngsters to pursue their “science and space dreams”, according to the manned space agency.

（2022·四川·宜宾市教科所三模）SpaceX, a private company, has put 60 Starlink communication satellites into orbit, bringing the total circling Earth to 180. They will bring internet access to underserved areas of the world. But it seems they also mess with telescopes.
When the satellites pass through a telescope’s field of view, they create bright streaks(条痕) that cut through images of the sky, hiding anything that might be behind them and pouring so much light into the telescope that it causes some observations unusable.
“What surprised everyone - the astronomy community and SpaceX - was how bright the satellites are”, said anxiously space experts. Actually SpaceX did talk about the issue elsewhere. The problem for astronomers doesn’t end with SpaceX. Blue Origin, One Web and Amazon plan to launch thousands of communications satellites in the coming years.
In an effort to ease astronomers’ fears, SpaceX is testing one satellite that is a bit different from the others. It was included in the most recent launch and is partially coated in a dark material to make it less shiny and so less visible in telescope images. We don’t have any data yet on whether the coating is working as intended.
Once the satellites are in space, there is no backtracking. While companies like SpaceX do need approval from regulatory bodies(监察机构) for each launch, there is no rule that prevents them from launching an unlimited number of satellites.
“We have to rely on firms such as SpaceX voluntarily cooperating with astronomers to attempt to keep the impacts of their satellite constellations (卫星星座) as low as possible.” said space experts.
With more than 1,500 Starlink satellites scheduled for launch in the near future, that cooperation will need to be speedy if it is going to make any difference.
5．Why does SpaceX launch so many communication satellites
A．To expand internet services worldwide.
B．To make users surf the Internet quickly.
C．To disturb the operation of telescopes.
D．To further present space research.
6．What are space experts worried
A．Satellites are too shiny to be seen.
B．Satellites occupy the area of telescopes.
C．Too many satellites move in outer space.
D．The normal use of the telescopes is affected.
7．What can be inferred from the passage
A．The number of satellite launches will decrease.
B．Coated satellites can effectively weaken brightness.
C．The regulations of satellite launching are not powerful.
D．SpaceX’s cooperation with astronomers remains to be seen.

（2022·重庆市涪陵高级中学校模拟预测）Space travelers face a number of health risks. Astronauts have reported loss of bones and muscle and some even have developed immune disorders and heart problems. A new study finds that energy-producing new structures in cells might be to blame for many of these problems.
A systems biologist, Afshin Beheshti, who studies how different parts of the body work together, also a member of a team of researchers that want to know how spaceflight might affect cells and tissues, notes, “It’s a basic question.”
The team looked at NASA GeneLab’s collection of data from past space biology experiments and studied cells and tissues from mice and people and compared space travelers with others that had remained on Earth.
“The idea is not only to look at one type of chemical,”Beheshti says. Rather, they wanted to “look at the living system as a whole”. And in doing that, they found a common theme. After some time in space, mitochondria, the energy powerhouses of cells, often didn’t work as well as they should.
Those findings are consistent with samples from NASA’s Twin Study. Before retiring, astronaut Scott Kelly spent nearly a year aboard the International Space Station. His twin, Mark remained on the ground. Afterward, blood samples from the two showed different mitochondrial activities.
For the latest study, Beheshti and his team studied GeneLab data for many types of cells and tissues. Another focus was related to metabolism. That process includes a mix of chemical activities that supports life in cells, organs and the whole body.
Damage to mitochondria may be a common factor in spaceflight health risks, the team now concludes. Finding similar changes in so many astronauts indeed points to some general effect, agrees Michael Snyder, a systems biologist at Stanford University in California, who worked on Scott and Mark Kelly’s Twin Study but was not part of the new analysis. If mitochondria are the cause, dealing with problems of them could help protect future astronauts. Some diseases cause mitochondrial defects(线粒体缺陷). Dealing with such diseases in different ways may help reduce astronauts’ health risks. Future studies could test if existing drugs prevent mitochondrial problems in cells, animals and people on long deep-space travels.
9．What might cause astronauts to have health problems according to the new study
A．Temperature difference. B．Heart cell increase.
C．Cell problems. D．Tiring work.
10．Which method did Beheshti’s team employ to do the research

B．They referred to some previous data.
C．They followed some astronauts for many years.
D．They observed behaviors of astronauts in person.
11．What may contribute to the decrease of astronauts’ health risks

（2022·河南·南阳中学三模）Humans have been exploring the infinite abyss (深渊) beyond Earth’s atmosphere. When astronauts explore the vast expanse of outer space, they need to wear high-tech spacesuits to protect them from the freezing conditions of the universe.
Hollywood movies have idealized the iconic suit, its design leading the masses to believe it’s an outfit that can be slipped on within minutes. In fact, the spacesuit which is made up of nearly a half dozen different components and can have up to 16 layers is its own fully functioning spacecraft that takes hours to put on and requires help from one’s colleagues.
The astronauts on the Artemis missions, NASA’s next program to send the first woman and the first person of color to the moon, will wear the latest spacesuit, called the exploration extravehicular mobility unit, also known as xEMU, according to NASA．
Each spacesuit has a portable life support system, which includes a water tank for the cooling garment and carbon dioxide removal system to regulate body temperature, remove excess heat and maintain the astronauts’ health, said Richard Rhodes, the deputy lead for xEMU pressure garment development at NASA．A two-way radio system is also included so the astronauts can communicate during the missions.
“When the Apollo astronauts walked on the moon, they couldn’t bend over and pick up a rock,” said NASA astronaut Mike Fincke. Fortunately, spacesuits have come a long way since then and have a more flexible structure with gloves. The gloves are one of the most complicated parts of the spacesuit, said Cathleen Lewis, curator of the Smithsonian Institution’s National Air and Space Museum. “Gloves are very difficult to design to be protective and also allow the manual dexterity (灵巧) that astronauts need to do meaningful work.” she noted.
The spacesuits will also be getting some upgrades for the latest lunar mission. Richard Rhodes’s team is working on the spacesuit that will allow for more movement to explore the rough terrain of the moon while still being strong enough to protect the wearer.
13．What can we learn about the spacesuit in Hollywood movies
A．It provides the most ideal design. B．It functions as a spacecraft of its own.
C．It can be put on without too much difficulty. D．It can protect the astronauts from the cold in space.
14．In what aspect does Paragraph 4 mainly talk about the latest spacesuit
A．Its operating methods. B．Its component parts.

（2022·青海·模拟预测）An experimental cleanup device called RemoveDebris has successfully cast a net around adummy (仿造的) satellite, simulating (模拟) a technique that could one day collect spaceborne garbage.
The test, which was carried out this week, is widely believed to be the first successful demonstration of space cleanup technology, experts told CNN. And it signals an early step toward dealing with what is already a key problem: rubbish in space.
Millions of pieces of junk are turning around in orbit, the result of 50 years of space travel and few regulations to keep space clean. At orbital speeds, even a small bit of paint crashing with a satellite can cause serious damage.
Various companies have plans to send thousands of new satellites into low-Earth orbit, already the most crowded area.
The RemoveDebris experiment is run by a company and researchers led by the UK’s Surrey Space Centre and includes Airbus, Airbus-owned Surrey Satellite Technology Ltd. and France’s Ariane Group.
Guglielmo Aglietti, the director of Surrey Space Centre, said that an operational version of the RemoveDebris technology would cast out a net that remains fastened to the main satellite so the debris can be dragged out of orbit. It could target large pieces of junk, including dead satellites up to 10meters long.
The RemoveDebris satellite will conduct a few more experiments in the coming months, including testing navigation systems that could help guide the satellite to a specific piece of debris. Jonathan McDowell, an astrophysicist at the Harvard Smithsonian Centre for Astrophysics, said the success of this week’s experiment was exciting, but he cautioned against “over-publicizing” it. There are still big barriers to clear before operational cleanup tasks will be underway, he said, and the biggest challenge is figuring out how to fund such projects.
Aglietti, the Surrey professor who helped lead the RemoveDebris project, said “the challenge will be to convince the relevant authorities to sponsor these tasks”. Aglietti said he hopes RemoveDebris will conduct a few cleanup tasks per year, targeting the largest pieces of rubbish in the most crowded orbits. Aglietti is hopeful.
17．What attracts people to invent RemoveDebris
A．Exploring space. B．Testing an orbit.
C．Cleaning satellites. D．Removing waste in space.
18．How does the RemoveDebris work
A．It throws a net to take junk from orbit. B．It fastens junk to the main satellite.

（2022·四川省泸县第四中学模拟预测）A satellite is about to demonstrate a new way of capturing space junk with magnets for the first time. With the frequency of space launches dramatically increasing in recent years, the potential for a disastrous collision above Earth is continually growing. Now, Japanese orbital clean-up company Astroscale is testing a potential solution.
The firm’s End-of-Life Services by Astroscale demonstration mission is scheduled to lift off on 20 March aboard a Russian Soyuz rocket. It consists of two spacecraft: a smaller “client” satellite and a larger “servicer” satellite, or “chaser”. The smaller satellite is equipped with a magnetic (磁力的) plate which allows the chaser to dock with it.
The two stacked spacecraft will perform three tests once in orbit, each of which will involve the servicer satellite releasing and then recapturing the client satellite. The first test will be the simplest, with the client satellite drifting a short distance away and then being recaptured. In the second test, the servicer satellite will set the client satellite tumbling before catching up with it and matching its motion to grab it.
Finally, if those two tests go well, the chaser will live up to its name by letting the client satellite float a few hundred metres away before finding it and attaching to it. All of these tests will be performed autonomously, with little to no human input once they are set in motion.
“These kinds of demonstrations have never been done before in space - they are very different to, say, an astronaut controlling a robotic arm on the International Space Station,” says Jason Forshaw at Astroscale UK. “This is more of an autonomous mission.” At the end of the tests, both spacecraft will burn up in Earth’s atmosphere.
If companies wanted to use this capability, they would have to attach a magnetic plate to their satellites so they could be captured later. Because of the growing space garbage problem, many countries now require firms to have a way to bring back their satellites once they run out of fuel or fail, so this could be a fairly simple likely plan, Forshaw says. Right now, each chaser can only nab one satellite, but Astroscale is working on a version that could drag three or four out of orbit at once.
21．Which of the following can replace the underlined word “dock with” in Paragraph 2
A．deal with B．keep up with C．join together D．crash
22．Why many countries now require firms to have a way to bring back their satellites
A．Because of the growing space waste problem.
B．Because the frequency of space launches are dramatically increasing.
C．Because they can earn large profits from it.
D．Because Astroscale has found a new method of capturing the space garbage.
23．What will Astroscale do to solve the space junk problem
A．An astronaut controls a robotic arm on the International Space to capture the “client” satellite
B．Through a magnetic plate remotely controlled by humans on the ground to catch the “client” satellite
C．Finding the “client” satellite and attaching to it with a magnetic plate automatically
D．Tumbling to match the motion of “client” satellite the drag three or four satellites out of its orbit into atmosphere.
24．What can we infer from the passage
A．people will burn the space junk up in Earth’s atmosphere in the future
B．Japan and Russia will conduct space debris cleanup experiment together
C．These kinds of demonstrations have never been done before.

（2022·湖南·长郡中学二模）China’s historic 23-day Chang’e 5 mission has not only obtained precious rock and soil samples from the moon, but has also brought back a group of seeds that traveled the furthest in the nation’s agricultural and forestry histories. More than 30 kinds of seeds were placed inside Chang’e 5 spacecraft and orbited around the moon for about 15 days.
Scientists wished to check what would happen to the seeds after being exposed to extraterrestrial(地外的)forces in lunar orbit and also hoped they could develop beneficial mutations (突变). This mission offered good opportunities to scientists, which enabled them to deepen their studies on the effect of cosmic rays on the growth and evolution of life on Earth.
Space-based mutation breeding refers to the process of exposing seeds to forces such as micro gravity, vacuums and cosmic radiation during a spaceflight and then sending them back to Earth for further observation and planting. Researchers observe and examine several generations of plants grown from space-bred seeds and investigate their mutations—some are positive and desirable while others are negative. Those with positive mutations will be kept and analyzed, and will be introduced to farmers after their certification and approval.
Space breeding can generate mutations faster and more conveniently than ground-based experiments and can bring about some desirable traits that are otherwise hard to pared with natural or conventionally bred types of plants, space-developed versions with positive mutations usually feature higher nutritional content, greater annual yields, shorter growth periods and better resistance to diseases and insect pests.
China conducted its first space breeding experiment in 1987. Since then, hundreds of kinds of seeds and seedlings have traveled with dozens of Chinese spaceships. Space breeding has helped to produce more than 200 new types of mutated plants in China that have been approved for large-scale cultivation, ranging from grains to vegetables and fruits. The Chang’e 5 robotic mission returned 1,731 grams of lunar rock and soil to Earth, marking a historic accomplishment 44 years after the last lunar substances were taken back.

（2022·湖北·荆州中学三模）A Spanish rice dish; secreto de cerdo with pisto—Ibérico Pork with tomatoes, onions, eggplant, and peppers; and chicken and mushroom paella, will be served aboard the International Space Station (ISS) throughout the next week.
That, at least, is what four of the eleven crew members aboard the ISS will be eating, after a SpaceX Falcon 9 rocket lifts off on April 8,2022 from Cape Canaveral, Florida, carrying the Crew Dragon spacecraft. The flight, sponsored by the Houston-based company Axiom Space and known as Ax-1, is commanded by Axiom vice president and former astronaut Michael López-Alegría. Also on board are three business owners and charitarians: American Larry Connor, Canadian Mark Pathy, and Israeli Eytan Stibbe—each of whom paid an estimated $55 million per seat for their 20-hour journey to the station and the eight days they will spend aboard.
Actually, they are not the first space tourists to the ISS—eleven in total over the past two decades; and all of them were adventurers who paid to fly aboard crewed by professional astronauts. AX-1 is the first fully private mission to the station—but not the last.
In a pre-launch press conference, Connor said, “We’ve spent anywhere from 750 to over 1,000 hours training. We’re going to do some 25 different experiments covering over 100 hours of research.” One such experiment will involve a brain headset that will conduct real-time electroencephalograms (EEGs) of the crew as they fly and experiments on in vitro stem cells.
There will also be time for a moving remembrance. Stibbe, the second Israeli to fly in space, once piloted military jets under the command of Ilan Ramon, the first Israeli astronaut, who died in the 2003 disintegration of the space shuttle Columbia. Several pages from Ramon’s diary survived the crash and Stibbe will carry them into the space.
Space is a hard business, a dangerous business, and an expensive business. But it’s also an emotional one. “Ramon was a good friend,” Stibbe added respectfully, “He was my commander.”
29．Why does the author show the dishes at the beginning
A．To present the whole menu in the space mission.
B．To attract readers’ interest and introduce the topic.
C．To show the enjoyment of the crew members during the flight.
D．To highlight the wealth and social status of the crew members.
30．What’s the main purpose of the mission
A．To maintain the ISS. B．To provide space travel.
C．To help people settle in space. D．To send Spanish food to space.
31．How does Connor think about the mission before he flies
A．Fully-prepared and significant. B．Expensive but worthwhile.
C．Difficult and dangerous. D．Adventurous and challenging
32．Why does Stibbe want to bring Ramon’s diary into the space
A．Because he wants to continue writing the diary.
B．Because he can use Ramon’s diary as instructions.
C．Because he once piloted military jets under Ramon’s command.

（2022·山东师范大学附中模拟预测）Astronomers breathed a sigh of relief as the James Webb Space Telescope(JWST)sprung to life. JWST would not fit into any modern rocket without being folded. However, ultimately the telescope has started returning some of its first images to thrilled audiences back on Earth.
Yet the experience left many astronomers wondering if there was a simpler way to launch telescopes of this size. “We were worried about the unfolding,” says John Blevins of NASA’s Marshall Space Flight Center. But with a larger rocket, “you don’t have to unfold in space. You can do it on the ground”.
As chance would have it, two such rockets are currently sitting on launchpads. The first, NASA’s Space Launch System(SLS), is ready and waiting at Kennedy Space Center in Florida for its voyage this summer. But a reliance on tried-and-true technology could be its Achilles’ heel: some estimates currently keep the SLS’s cost at an $4.1 billion per launch. If approved, though, its massive size could ultimately be a boon for scientists seeking to send larger, more ambitious spacecraft and telescopes throughout the solar system and even beyond.
Over in Texas, Starship, a similarly capable but wildly different rocket being developed by SpaceX, is also in preparation to launch on its first orbital test flight. Usually, each rocket will be deserted after a single use, its components degraded to junk on the seafloor or adrift in space. But Starship is instead built for endurance, landing back on the ground for rapid reuse, which has already dramatically lowered the expense of reaching space.
As big and bold as the SLS may be, experts say that it pales in comparison with what Starship could achieve. “Starship holds the promise of transforming the solar system in a way we can’t really appreciate,” says Alan Stern. “It completely changes the game.”
33．Why was it necessary to simplify the way to launch JWST
A．The size of some rockets was small. B．The launching technology was limited.
C．The unfolding of JWST was impossible. D．The cost of launching JWKT was costly.

Riding a horse at a high speed on grassland covered with snow while dressed in a red cloak (披风) and a white fur hat isn't something people would normally see a Chinese government official do. So it's not surprising that He Jiaolong, a female official from Xinjiang Uygur Autonomous Region, almost instantly became an online celebrity after she posted such a video.
She came up with the idea to make the video when she was thinking about new ways to let more people know about the famous horse breed (品种) of Zhaosu County, Ili, known as “heavenly horses”.
“I never expected the video to be such a hit. At first, I really didn't like to be called an online celebrity, because l never wanted to be one. But now I'm gradually getting used to using my influence to boost local development, she said.
Besides posting short videos, she has also been promoting local agricultural products and tourist resources via livestreaming (直播). With more followers, she can now help to sell local products worth more than 2 million yuan during a livestream while sales were only about 5,000 yuan each time when she first started to livestream on social media.
While she continues to draw the public's attention to Ili, she also has to keep dealing with the stress brought by criticism, especially often being questioned if being a social media celebrity may affect her work as an official. She said that she had even thought of giving up appearing on social media several times.
“I am, above all, a government official. I will never let what I do on social media affect my job,” she said. “I want to see the locals appreciate my efforts in serving them, which is my duty. I hope people can feel the warmth and positive energy of Xinjiang officials via my videos. I am simply one of them.”
1．Why did He Jiaolong first make her videos
A．To introduce her job.
B．To gain personal fame.
C．To promote a horse breed.
D．To advertise the local scenery.
2．What can we learn from He Jiaolong's words in Paragraph 3
A．She enjoys being called an online celebrity.
B．She is proud of her skills of making short videos.
C．The video's success makes a difference to her life.
D．The video's success damages her image as an official.
3．What changes has He Jiaolong's livestreaming brought to Ili
A．Sales of local products have been increased.
B．Lives of local residents have been disturbed.
C．More local officials join her in livestreaming.
D．More followers make videos of the local scenery.
4．How does He Jiaolong react to people's criticism

B．She apologizes to the local government.
C．She consults experts on dealing with the stress.
D．She continues serving people through her efforts.

（2022·河北保定·高二期末）With the popularity of the Internet in recent years, major webcast platforms are in full swing, especially in this special period, many people are staying at home, crazy to engage in webcast. We should treat this problem in a dialectical way of thinking. Everything that is beneficial will have disadvantages. Today, with the rapid development of the Internet economy, “webcast” has become a means of information spreading. Today, with the popularity of webcast, we should comprehensively analyze its advantages and disadvantages.
“Webcast” has become a hot word, and even derived a series of new industries and new occupations, effectively promoting the development of social economy and the diversification of business forms. For example, in the stage of resumption of work and production after the epidemic was effectively controlled, the live broadcast of network anchors promoted the rapid growth of some regional economies to a certain extent. For example, CCTV invited live broadcast talents such as Li Jiaqi and Weiya to combine with stars to carry out live broadcast in Wuhan and other areas with serious epidemic, which effectively and rapidly promoted the economic development of Wuhan at that time. At the same time, educational live broadcasting can make up for the gap between education in backward areas and advanced areas to a certain extent, give children equal opportunities to learn, promote the national plan of educational equity, and let more children see the outside world.
But webcast also brings many problems. First, the quality of live broadcast goods is uneven. Many live broadcasters push and sell the goods in a template manner without detailed understanding. After customers receive the goods, the goods are not the right board. Because of logistics express fees and other reasons, they are also too lazy to argue, resulting in a gradual decline in public praise. Second, while bringing joy and economic growth, the live broadcast of online celebrity has made the social atmosphere more impetuous. The children’s ideal has become “I want to be an online celebrity”, thinking that there is food by one face. These dregs need to be abandoned. Third, the supervision of webcast is not strict, and vulgar information often appears, which brings bad social atmosphere.
To this end, we should first strengthen the supervision of webcast from the institutional level, especially the examination and approval of live broadcast content, standardize all live broadcast platforms, increase punishment, curb the bad live broadcast atmosphere from the source, and set up relevant vocational skills training according to the situation; Secondly, all broadcasters should effectively choose the live broadcast content, conform to the mainstream social value orientation, ensure the quality and level of live broadcast, and gradually get out of the mindset of echoing others; Finally, all public opinion media should create a positive and sunny attitude at the social level, treat the new thing of “live broadcasting” correctly, and guide public opinion to the right track.
10．What does the second paragraph say about webcast
A．Webcast can promote regional economic development and narrow the gap between urban and rural areas.
B．Webcast allows more children in cities to see the outside world.
C．The goods sold by webcast are of poor quality.
D．We should adhere to the correct guidance of public opinion when dealing with live broadcasting
11．What are the disadvantages of webcast mentioned in the article
A．Cause network congestion. B．Endanger national security.
C．Bring bad social atmosphere. D．Cause death of people.
12．What is the meaning of the underlined words in the third paragraph of the article
A．shabby B．common C．foolish D．silly
13．What is the purpose of the author’s writing the first paragraph
A．Challenge B．Attract reading interest C．Make a summary D．Come to the point

（2022·四川省南充市第一中学高三期末）“Ni Hao! I am your foreign friend. Just have a bite of our organic apples (有机苹果) and place your orders here!” Erik Nilson, a Swedish traveler, greeted through TikTok livestreams (抖音直播) in a village of Jiangxi Province. His livestreams increased that day’s sales greatly. After experiencing a special day of livestreaming, Erik said jokingly. “I wish I could change my job.”
This village is not alone. Nowadays, China’s e-commerce platforms (电商平台) like TikTok and Taobao have helped open up online markets for Chinese farmers’ produce. This has made livestreaming sales a new way to help poor farmers, with mobile phones becoming “new farm tools”.
“How can you make the audience believe that your products are delicious just through the screen in front of you ” The government in Hainan Province invites experts to teach farmers some necessary skills including how to make short videos and how to increase livestreaming sales. “However, at first, only a few villagers gave it a shot. So we helped them get training in livestreaming, short video marketing, and other courses. It wasn’t fancy, but simple, practical, and effective.”
“Everybody, please take a look. This is the best banana. Taste it.” said Pei Yanqin, 59, speaking with a strong local accent but communicating carefully with audience through her livestreaming software. Just over a year ago, she was one of those villagers with the least interest to get training.
Today, the village has developed eight e-commerce livestreaming courtyards. Some farmers work alone, while others are husband and wife teams. In the next step, the government will train more farmers to conduct the livestreams and develop multi-variety online sales.
