I am Turere. I come from Kitengela, a farming community on the edge (边缘) of Nairobi National Park of Kenya (肯尼亚). Since the age of nine, I have helped to look after my family’s cows. As a child, in my free time, I enjoyed playing with electronics. I made my own inventions, such as electronics toys from car parts and other things. I also built other electronic devices (仪器) for my neighbors.
At the age of 13, I invented something that changed my life. It also changed the lives of many people in my community. One night, a lion from the park came into my family’s farm and killed one of our cows. I was angry. However, killing the lion, I thought, was not the best way to solve the problem. Instead, I decided to invent a solution.
The first idea I got was to use fire, because I thought lions were scared of fire. But I came to realize that didn't really help, because it was even helping the lions to see through the cowshed (牛棚). So I didn't give up. I continued.
And a second idea I got was to use a scarecrow (稻草人). I was trying to trick the lions [into thinking] that I was standing near the cowshed. But lions are very clever. They will come the first day and they see the scarecrow, and they go back. But the second day, they'll come and they say, this thing is not moving here, it is always here! So he jumps in and kills the animal.
So one night, I was walking around the cowshed with a torch (手电筒), and that day the lions didn’t come. And I discovered that lions were afraid of a moving light. So I had an idea ...

The world’s largest radio telescope was finished on Sept. 25, 2017 in China.
FAST is a five-hundred-meter telescope. It is also called Tian-yan (“The Eye of Heaven”), with a dish the size of 30 football grounds, deep in the mountains of southwest China’s Guizhou Province. The giant dish is built on a bowl-like valley.
The surrounding area has “radio silence” as there are no towns and cities within a 5-kilometer radius(半径范围) and only one county center within 25 kilometers.
FAST is made up of 4, 450 panels(面板). The second largest radio telescope is in Russia. The bigger dish will be able to pick up weaker signals(信号).
The radio telescope is like an ear, listening to tell meaningful radio messages from white noise in the universe. With the help of the telescope, we can receive weaker and more radio messages far away in space. It will help us to search for intelligent life outside of the Galaxy(银河系) and explore the origins(起源) of the universe. “Any of its discoveries will lead to a Nobel Prize,” said Joseph Taylor, a Noble Prize winner.
The FAST project began in 2011. And the telescope is expected to remain the global leader for the next 10 to 20 years.
41. Where was FAST developed?
A. In China. B. In Russia. C. In America.
42. The underlined word “giant" probably means “_________” in Chinese.
A. 神秘的 B. 巨大的 C.宽广的
43. FAST is used to _________.
A. explore the origins of human beings
B. receive distant radio messages from the universe
C. watch the beautiful scenery of the Galaxy
44. From the passage, we can know that __________.
A. FAST is the largest radio telescope all over the world so far
B. Noisy towns are around the telescope within a 5-kilometer radius
C. The second-largest radio telescope is made up of 4, 450 panels
45. How long did it take to finish the FAST project?
A. About twenty years. B. About ten years. C. About six years.

We all need cash (现金) in order to live our lives. However, something called digital currency is slowly taking the place of cash. A currency is a kind of money. Usually, we use currency when we talk about a country’s money. If something is digital, it only exists (存在) on a computer. So “digital currency” means money that only exists on computers.
Lots of people have digital currency accounts (账户). they use a credit card (信用卡) to change their real money into digital money, and then the money goes into the digital currency account. A lot of people wonder, “Why in the world should I change my real money into digital currency?” this is a fair question, but there’s a good answer. If you want to buy something online, then you usually have to use digital currency. For example, if you’re in China and you want to buy something in Canada, then you’ll have to pay with digital currency.
Many people still don’t trust digital currency. Some people think that if they can’t hold their money in their hand, then it doesn’t seem real. These people don’t feel comfortable when they see numbers on a computer screen. The computer tells them that their money is safe but these people don’t really feel safe. Another problem is security (安全). There are hackers all over the world. A hacker is a person who steels computer information. If a hacker gets the password of your digital currency account, he or she can steal your money.
You have to decide whether or not you trust this new invention. Just remember one thing: If you want to buy something online, then you probably won’ have a choice. You’ll have to digital currency.
?27.?What does Para.1 mainly tell us?
A. What digital currency is. B. How to use digital currency.
C. Why we all need cash to live. D. Where to find digital currency.
28. What is the “good answer” to the question in Para.2?
A. You cannot shop online without digital currency.
B. You cannot buy anything in China with real money.
C. You cannot buy anything in Canada without digital currency.
D. You can use both real money and digital currency to shop online.
29. What is the first problem mentioned in Para.3?
A. Digital currency is not safe enough.
B. Many people still don’t trust digital currency.
C. Some people can’t hold their money in their hand.
D. Some people don’t feel comfortable with numbers.
30. Which of the following is the best title for the passage?
A. Two kinds of money B. The end of real money
C. Currency around the world C. Money that you can’t touch

Earlier this year, China achieved a new milestone (里程
碑) in space research. On January 3, 2019, Chang’e-4
became the first lunar probe (月球探测器) in history to
successfully land on the far side of the moon.
The Earth’s gravity (重力) shows the moon’s rotation
(自转), matching it to the speed of its orbit (公转). Therefore, the far side of the moon is almost “dark” and has never been seen. It’s this sense of the unknown that makes the far side of the moon such as interesting place for scientific and space research. Being blown by solar (太阳的) winds, the far side may have the special minerals (矿物质). For this reason, Chang’e-4 will study the effect of solar winds on the lunar surface and any mineral found by the spacecraft. Chang’e-4 is also carrying flower seeds, potatoes and silkworm eggs to see whether life is possible on the moon.
If it is, then the moon will become a possible choice for space travel in the future.
However, research of the “dark” side isn’t easy. As the side is blocked (阻断) off from us, radio noise coming off Earth is also blocked. This is why China’s relay satellite (中继卫星) Queqiao was sent up in May, 2018. Thanks to Queqiao, the communication problem between Earth and Chang’e-4 has been well solved.
Power supply (电源供应) is also a challenge to the task. Chang’e-4 gets energy from the sun through its solar panels. As we know, a lunar day has the length of 28 Earth days. After Chang’e-4 was sent up on December 8, 2018, it took the probe over 20 days to orbit the moon to be in a position to be able to land in moon daylight and use its solar panels.
Luckily, everything goes well. Chang’e-4 has worked on the “dark” side for over 5 months. It has sent back many photos of the far side of the moon and has been used to carry out some scientific experiments.
The New York Times used the word “groundbreaking” to praise the task and wrote that “it will offer help to the history and development of the moon.”
47. When was Chang’e-4 sent up?
A. In May, 2018. B. On December 8, 2018.
C. On January 3, 2018. D. The passage doesn’t tell us.
48. The main tasks of Chang’e-4 doesn’t include ______.
A. studying if life is possible on the moon
B. studying the effect of solar winds on the lunar surface
C. studying the communication problem between Earth and other probes
D. researching any mineral found by the spacecraft
49. The meaning of the underlined word “groundbreaking” in the last paragraph is the closest to “______”.
A. harmful B. unpredictable C. risky D. pioneering
50. According to the passage, which of the following statements is NOT true?
A. Chang’e-4 has sent back many photos of the far side of the moon.
B. A lunar day has the length of 28 Earth days.
C. China’s relay satellite Queqiao was sent up in order to offer power to probes.
D. Chang’e-4 is the first lunar probe in history that has successfully landed on the “dark” side of the moon.

Personal computers and Internet give people new choices about how to spend their time．
Some may use this freedom to share less time with certain friends or family members, but the new technology will also let them communicate more with those they care more about．I know this from personal experience．
Email makes it easy to work at home. I spend most weekends and evenings at home．My working hours aren’t much shorter than they once were but I spend fewer of them at the office．This lets me share more time with my young daughter than I might have if she’d been born before Email became such a practical tool．
The Internet also makes it easy to share ideas with a group of friends．Say you do something fun—see a great movie perhaps and there are four or five friends who might want to hear about it．If you use a telephone to call each one, you may tire of telling the story．With Email, you just write one note about your experience, at your convenience, and send it to all the friends you think might be interested．They can read your message when they have time, and read only as they want to．They can reply at their convenience, and you can read what they have to say at your convenience．
Email is also an inexpensive way to communicate with people who live far away．More than a few parents use Email to communicate with their children at college every day．

If you look at the top of your phone, you’ll usually see a little symbol that says 3G or 4G. The “G” stands for the “generation”(代) of your mobile network. But the symbols will become things of the past after 5G networks fully arrive.
On March 30, Shanghai vice-mayor Wu Qing made the first 5G video call on a Huawei Mate X Smartphone. Shanghai has also become the first city in China to start testing 5G networks.
About 100 times faster than 4G networks, 5G will let people download and upload data (数据) faster than ever before. But 5G won’t just bring faster mobile internet. People can use it for many other things as well.
For example, 5G will help to make self-driving cars safer. Today’s self-driving test cars have one problem—lag (延迟). When the car “sees” an obstacle(障碍物), it sends this information to a data center and receives instructions. However, it will be some time before it sends and receives this information. With this kind of lag, the cars might crash because they don’t receive instructions in time. With 5G, this lag will be greatly lowered, making the cars safer.
5G could also be used to power the internet of things (IoT), that is, a large online network that connects all things and people. Fast internet speeds will be the key to developing this technology. The loT could be used in a lot of ways. For example, with IoT, your refrigerator could automatically (自动地) place an order online for eggs when it finds that there are no eggs left inside.
61. Which city was 5G tested for the first time?
A. Beijing. B. Shanghai. C. Shenzhen.
62. What can we infer (推测) according to the passage?
A. 5G is widely used in China now.
B. 5G networks will make our lives more convenient.
C. There are no symbols at the top of our phones.
63. The writer used self-driving cars as an example to ________.
A. explain how 5G’s fast speed can be helpful
B. warn about the possible dangers of self-driving cars
C. explain how self-driving cars work
64. What is IoT according to the passage?
A. A robot that can do housework.
B. An online store where you can buy anything.
C. A large online network that connects things and people.
65. Which sentence is right according to the passage?
A. 5G will help us buy eggs quickly.
B. Robots can help us buy eggs online.
C. Our refrigerator can order eggs online for us.

“Made in China” is having its moment now—and it’s a fashionable one.
The story of Chinese fashion began in 2011 when Feiyue and Huili, both Chinese sports shoe brands(品牌), suddenly got international attention. Their products were seen all over the world. Chinese sportswear brand Li Ning was at the New York Fashion Week in September, 2018. They showed their new designs—sweaters and jackets with Chinese characters.
Shaun Rein, managing director of China Market Research Group, said that the latest Chinese brands no longer catch customers’ eye by low price. He told CNN, “They are sure that they can go head to head with foreign brands.”
Maybe it is because China’s young people are now more confident about their own culture. They don’t show immediate interest in western culture any more.
“Today’s young people in China are crazy about Chinese cultural elements(元素),” Jin Qu, the manager of a clothing shopping website, said at a cultural festival in 2018. “They like these elements printed on their clothes, even the brand picture of Laoganma in China, which was once seen as outside of fashion. But now young people are proud of these Chinese symbols.”
In fact, many stars in the West are now interested in Chinese cultural elements in fashion. Rihanna, a US singer, for example, wore a Chinese red dress to the 2015 Met Gala in New York. The dress was designed and made by Chinese designer Guo Pei.
“We have to move from making to creating,” Chinese-American designer Aric Chen once told The New York Times. “We want to replace the words ‘Made in China’ with ‘Designed in China’.”
34. The new designs of Li Ning Company in September, 2018 were ________.
A. coats and scarves in Chinese red
B. sweaters and jackets with English words
C. coats and scarves with American symbols
D. sweaters and jackets with Chinese characters
35. The underlined word “They” in Paragraph 5 refers to ________.
A. today’s young people in China
B. the workers in Jin Qu’s shop
C. some famous stars in the West
D. Directors of some Chinese companies
36. What can be the best title for the passage?
A. Chinese Clothes Brands B. Sports in China
C. Chinese Cultural Festival D. Designed in China
37. The passage above may be taken from a(n) ________.
A. newspaper B. guidebook C. novel D. ad

Brooke wanted a dollhouse and some sugar cookies. So the 6-year- old asked Alexa to get them. Alexa wasn’t her mom or babysitter. It was a voice-activated home assistant powered by AI (人工智能). And it made Brooke’s wishes come true. A few days later, much to her parents’ surprise, a $ 170 dollhouse and four pounds of cookies showed up. They ate the cookies and gave away the dollhouse to a local hospital. And that’s not the end of the story. When a news reporter told the story of what happened on TV. Alexa devices (设备) in many listeners homes woke up and tried to order dollhouses!
Alexa isn’t the only AI willing to serve you. Apple Homepod has Siri, Google Home has its Assistant, and the upcoming Galaxy Home device will have Bixby. People who have these devices use them mainly for listening to music, checking the weather, and setting timers. According to a report from The Information, nowadays voice shopping is rare. But many scientists predict a boom (增长) in voice shopping in the near future. Is that a good thing?
.You can shout out an order as soon as you think of it, even if you are cooking, cleaning, or driving. In addition, people with disabilities who are unable to use a keyboard or mouse can shop without any help.
But voice shopping has its disadvantages. Unwanted dollhouses aren’t the biggest problem. It’s usually very easy to cancel an order or return products. The thing that worries some people is that these assistants are always listening. They have to be able to respond when you want them. So they listen for “Alexa” or “OK Google” or another order. When they hear it, they start recording the conversation. Some have worried about what happens shopping habits? And what if someone hacks (入侵) the device? The CIA found a way to hack smart TVs to turn them into spies that listen all the time. Others could do the same with any smart device.
What do you think? Are you ready to start voice shopping?

Many objects in the universe are invisible*, but they send radio waves. The radio telescope* thus appeared, and it is considered one of the greatest inventions in the twentieth century. Reber built the world’s first radio telescope in 1937. Ryle and Hewish developed radio telescope systems for the location of weak radio sources, and they shared the Nobel Prize for Physics in 1974.
A radio telescope is usually made up of:
◆One or more antennas to collect the radio waves. Most antennas are made in the shape of a dish to collect and reflect* the radio waves to the sub-reflector, in the same way as a curved mirror focuses visible light to one point.
◆A receiver and amplifier to receive the radio waves from the sub-reflector, and make these weak radio waves strong enough to be recorded and turned into electronic signal*. To make an amplifier sensitive enough, it is usually cooled to very low temperatures (e.g. as low as ―270℃).
◆A recorder to keep a record of the electronic signals. Most radio telescopes today keep the signals to the computer’s memory disk for astronomers to analyze later.
Radio wavelengths are much longer than those of visible light, and the radio waves from deep space are always weak. To catch these waves, radio telescopes usually have huge antennas. The sizes of most antennas in use today are around 50 to 300 metres in diameter. The antenna of FAST in Guizhou, China, the latest and largest radio telescope in the world, is 500 metres in diameter, as large as the size of 30 football fields.
To avoid interference, and keep the telescopes sensitive, radio telescopes are built in places where there are no human radio waves or electronic signals. For example, FAST is 5 kilometres away from the closest village and 25 kilometres away from the nearest town.
Radio telescopes create pictures of the sky, not in visible light, but in radio waves. This is extremely useful, because there are objects that can’t be seen, objects that we wouldn’t even know were there without telescopes.
33.Radio telescopes help collect ________ from the universe.
A. light B. objects C. radio waves D. visible signals
34. Most antennas of radio telescopes are made in the shape of dish to________.
A. make the antennas strong enough B. increase the number of radio waves.
C. turn radio waves into electronic signals D. focus radio waves on the sub-reflector. 35. The underlined word “Interference” in the passage refers to________.
A. the noises made by villagers and animals
B. the sounds from the radios and televisions
C. the people who go to Guizhou to watch FAST work.
D. the radio waves and electronic signals from humans
36.What have we done with the help of radio telescopes?
A. We have received pictures of deep space.
B. We have discovered unknown lives in the universe.
C. We have found some unknown objects in the universe.
D. We have turned the radio waves from space into light.
