（陕西宝鸡·一模）Whether from news reports or social media articles, you may know that 5G is coming.
5G is the 5th generation network. It is a new network after 1G, 2G, 3G and 4G. It can connect everyone and everything together. 5G networks will cover many cities in China soon. 5G means super-fast data speed. One can download a two-hour movie for fewer than 10 seconds, and it is making our lives more and more convenient.
5G will make self-driving cars possible. For safety, self-driving cars need super-fast data transmission (传输) to communicate with their nearby environment. 5G is just what makes self-driving cars achieve this. Even airplanes will become “smart” in the near future. Passengers will be able to use 5G networks in the air to connect to the Internet and can order for food and drinks.
5G will be a big help for students who take online classes. Many people live in poor areas in the world where there are no schools. But with 5G, this will change. Students all over the world will be able to see places like the Great Wall without leaving their rooms.
It will be also easier for doctors to treat patients remotely by 5G. It means caring for patients from far away.

When visitors to the Palace Museum feel a need to sit down for a cup of tea or find a bathroom without a long line, they soon will be able to turn to their smart phones for the information they need.
This modern solution comes thanks to an agreement signed on Friday by the museum and Huawei Co., the telecommunication giant, to build a “smart network” using 5G technology. Under the agreement, 5G Wi-Fi signals will cover the Palace Museum, China’s royal palace from 1420 to 1911.
“It’s important to always stay close to the latest technology to better serve the public,” said Shan Jixiang, former director of the Palace Museum. Shan said there is still much room for improvement in the handling of a huge number of cultural relics,such as when the priceless painting “Along the River During the Qingming Festival” is exhibited again in the future. When it was last exhibited in 2015, visitors stood in long lines until 3 am to have a look. The museum ended up preparing fast food to serve the hungry visitors. “I don’t want that scenario to happen again,” Shan said. “Our operation can be done in a more scientific way.
The new system will also make use of the closed-cameras that are set up all over the Palace Museum to safeguard the museum’s precious relics. More than 1.86 million of them are housed at the museum, which recorded nearly 20 million visits from the public last year. “How can we make sure no single visitor who might have evil ideas threatens these treasures ” Shan said. “After adopting the internet of things, we can instantly detect any motion involving the relics to prevent such threats.”
The 5G network also will be used to improve remote meeting through webcams, which will discuss with scholars to jointly find the best answers for repair and store issues.
5．What do we know about the Palace Museum
A．Its visitors won't have to queue up for the bathroom.
B．It has served as China’s royal palace for over 500 years.

（山东济宁·一模）There is much heated discussion today about 5G. Your Internet experience is not pleasant when the net speed is too slow — it takes so long to open a web page and the talk show you’re watching stops every few minutes. But soon it could be a thing of the past. On June 3, 2020, the Chinese government announced (宣布) that 5G services would be provided around the country.
5G is the 5th generation network. It is a new network after 1G, 2G, 3G and 4G and it can connect everyone and everything together. 5G speed can be very fast. In the near future, 5G network will cover many cities in China.
5G will make self-driving cars possible. For safety, self-driving cars need super-fast data transmission (传输) to communicate with their nearby environment. 5G is just what makes self-driving cars achieve this. Even airplanes will become “smart” in the near future. Passengers will be able to use 5G networks in the air to connect to the Internet or order food and drinks.
5G will be a big help for students who take online classes. In the world, many people live in poor areas where there are no schools. But with 5G, this will change. Students all over the world will be able to see places like the Great Wall without leaving their rooms.
In addition, 5G will be used in hospitals. It will be easier for doctors to care for patients who live far away by 5G.
However, 5G has its own weaknesses. According to China National Radio, though 5G will make our lives easier, it will not be perfect. For one thing, 5G will not “travel” far.

（浙江·模拟预测）
These days, both augmented reality (AR)* and virtual reality(VR)* are still something new and they are just toys because of their high cost and data usage. However, not too long from now, 5G will make them much more common both at work and in our homes. You might see people wearing AR glasses or VR headsets* while waiting for the bus or sitting in the office.
One of the most expected changes will be VR and AR’s influence on the gaming industry. Nowadays, most VR games are limited when compared to the latest console games*. With the power of 5G, VR gamers will be able to see, hear, and feel virtual environments without waiting. What’s more, if you want to play a game using a VR headset, you need a machine such as a PC or a gaming console that has a large amount of storage. This means you usually have to stay in one place while playing VR games. The arrival of 5G means we will be able to move advantages and disadvantages away from the PC and into the cloud so that we only need a headset. You will be able to play VR games anywhere in real time with a headset.
Such headsets and other 5G wearables will also bring great changes to the workplace. In 5G smart factories, for example, all of the equipment is connected to a single network. Workers can use 5G headsets when solving problems. Using AR headsets, they can be informed about a problem and shown how to fix it through a heads-up display.
AR adds digital elements* to real-world environments through a smartphone or a pair of smart glasses. One example is Nintendo’s AR Pokemon Go game, which uses a phone’s GPS to show Poké mon as if they are actually in the real world. VR is total immersion* in a 3D computer-generated environment. Users can interact with the environment using VR headsets and gloves. VR is typically used for computer games or in exhibitions.
42．In Paragraph 1, we know that ________.
A．It is common to see people wearing AR glasses now
B．5G will make AR and VR technology more popular
C．VR and AR technologies solved lots of problems in offices
D．people will use AR and VR for games only in bus stations

（陕西宝鸡·一模）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” of your mobile network. But the symbols will become things of the past after 5G networks fully arrive.
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 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-when they found something in front, that is too late to stop at once. When the car “sees” something in front, 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(滞后), the cars might crash because they don’t receive instruction in time. With 5G, this lag will be greatly lowed, 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 IOT could be used in a lot of ways. For example, with IOT, your refrigerator could automatically place an order online for eggs when it finds that there are no eggs left inside.
46．According to the passage, people in Shanghai ________.
A．have used 5G networks
B．have tested 5 in Nokia Company
C．have tested 5G networks under the leadership of Wu

（四川达州·中考真题）
In 1987 a small company named Huawei was started in Shenzhen. After more than 30 years of development, the company has now beaten Apple and become the world’s second largest maker of smartphones. It has also become the world’s supplier (供应者) of 5G. In China and even in the world, Huawei is a wonder. Although it started producing mobile phones not many years ago, it has become one of the most famous phone companies.
But recently, Huawei faces some difficulties. The US government made a law to stop its sales in America. American officials said Huawei gave information that it collected to the Chinese government. At the same time, the US government planned to stop selling parts and services to Huawei. They believed that Huawei’s business would be hurt this way.
“We have never received such a request from the Chinese government and we have never tried to get into other systems to collect information,” Ren Zhengfei, Huawei’s president said. “The law would have little effect on our company. Huawei has enough ability to deal with the problems,” Ren added.
In an interview several years ago, Ren Zhengfei said, “I started Huawei with only 4000 at the beginning, but now it has become a 100 billion company. The experience was not as romantic as you imagine.”
Facing the law of the US, Huawei is growing. Huawei’s smartphone sales around the world rose 50 percent compared with a year earlier in the first three months of 2019. At the same time, sales from both Samsung and Apple fell. So far Huawei has grown into the world’s largest telecommunication equipment supplier (供应商), selling in 170 countries. It may beat Samsung as the largest smartphone maker in the near future.

（江苏江苏·一模）Do you know 5G It is the fifth generation of mobile network technology. These new networks are coming.
China just issued commercial licenses （发放商用牌照）for 5G on June 6, 2020. This means that China’s telecom companies were soon 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（毫秒）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 dur 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+transportation
5G will also bring us safer self-driving cars. These cars can send signals （信号）to each other. They also talk to traffic lights and road sensors （传感器）. 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（自动地）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.
59．What does the underlined word “delay” in Paragraph 4 probably mean in Chinese
A．传输 B．延时 C．断开 D．卡顿
60．5G will change people’s lives in many ways EXCEPT ________.
A．entertainment B．transportation C．smart homes D．health
61．What’s the main idea of the passage
A．Mobile phone users can use 5G networks.

China announced the start of 5G in 2019 and now we can use 5G in many cities. As we can see, 5G has brought some great changes.
As a result of the increased size of networks, data transfer (数据传递) becomes much faster. 5G is 10 to 100 times faster than the speed of the 4G network. It may make many new uses possible. For example, you can download a film in just 3 seconds. This used to take a few minutes with a 4G network. What’s more, there will be enough capacity (容量) for everyone to chat online and watch movies on their phones. Scientists say 5G will help the development of self-driving cars and the “5G man-like robot” as well. Most importantly, 5G will help us build the Internet of Things ( IoT, 物联网).For example, on a hot summer day, you could turn on your air conditioning with IoT before you go home. All of these things need very fast Internet speeds. 5G will be the key.

（广东·秀全中学一模）Some people like the freedom of driving their own cars. But others find driving to be inconvenient or even dangerous. Fortunately, the driverless cars we've seen in movies and TV shows are on the way here.
The first driverless car to hit the screen was Herbie, a cute talking car from the 1968 comedy The Love Bug. Herbie could drive by himself and even talk to his human friends He didn't have any advanced technology—just magic.
KITT was another driverless car that appeared on the 1980s TV show Knight Rider. KITT used advanced Al to drive itself and help its rider Michael Knight catch criminals.
While the driverless cars of today can't talk to us, they do have many similarities to the ones we've seen onscreen. Nearly every major car company is working on their own autonomous, vehicle（AV）. Tesla, for example. has developed a driver-assistance system for its cars called Tesla Autopilot.
Tesla Autopilot can complete many of the tasks hat human drivers usually do. It can make sure that your car is centered in the correct lane, as well as park itself and stop if it thinks that a crash might happen. However, it is not fully self-driving.
Google's sister company Waymo seems to be leading the way in the AV area. Its self-driving cars are already being used for taxi services in the US city of Phoenix. It is the only self-driving car service that operates without human backup drivers. It uses common cameras as well as laser radar to determine distance, which allows the cars to get around without risk of crashing.
Although companies are making great progress in developing AV. there is still a lot of work to be done. Year after year, companies promise that fully self-driving cars will become widely available. But nearly all of these promises have fallen through.
One of the problems is that designing a self-driving car that is safe and easy to use is much harder than people realize. Self-driving cars have to analyze millions of data-points in order to prevent accidents and choose the correct route. Humans are used to doing this—but designing an Al that can work like human mind to make a decision quickly is very difficult.
However, as new technologies like 5G develop, fully self-driving cars will come closer to reality.
67．What were Herbie and KITT
A．They were interesting TV shows. B．They were driverless cars onscreen.
C．They were cars using advanced AI D．They were owners of driverless cars

（湖南张家界·一模）China is running ahead in 5G. In March, 2019, the Shanghai Hongqiao Railway Station became world's first "5G railway station". Now, it takes only 20 seconds to download a long movie there.
We are moving closer and closer to the 5G world. However, the new technology is still strange to most of us. What is 5G, after all At first, 5G is fast. 5G will be much faster than today's 4G networks!
The first 5G modem (猫，调制解调器) of the IT company Qualcomm supports speeds of up to 5 Gigabytes (千兆字节) per second. Most of us have never experienced anything close to that speed. And we are only talking about the first generation (一代) of 5G modems. Future models are likely to be even faster.
But 5G is not all about speed. Have you ever been to a large event where your data (数据) connection slowed down That is because 4G networks can only support a certain number of devices (设置) per square meter. 5G networks will be able to do much better. They can support up to a million devices per square kilometer.
Now, you begin to understand why 5G is a huge change over 4G. The technology is not just for the smart phones. It has a strong influence(影响) on every connected device. With 5G, self-driving cars will be able to communicate with the world around them as quickly as possible. Wearables, Pcs and smart home devices will be able to improve as well.

（广东·珠海市前山中学模拟预测）On the morning of May 30th, 2019, Huawei helped the BBC use 5G to report news. It was the first time that 5G was used in the world! Actually, China just began to use 5G in June 2019. What’s the most special about 5G 5G lets us send and receive information in a very short time. Now, 4G takes about 100 to 200 milliseconds（毫秒）to send and receive information. But 5G will the time down to 1 millisecond or less. The big change that 5G brings will not only make our mobile network faster, but also deeply change our lives in many ways.
First, 5G can connect with amusements. 5G is about 100 times faster than 4G. This means you can download a movie in seconds by using 5G. Also, VR games will become more popular with 5G. 5G will make people feel the games even more real.
Second, 5G can connect with traffic. 5G will also make self-driving cars safer. These cars can send messages to each other. They also “talk” to traffic lights and road sensors（传感器）. 5G will allow self-driving cars to have faster reaction than human drivers.
Third, 5G can connect with smart homes. 5G also makes the IOT possible. IOT is a large network that connects everything to the Internet. Smart homes are part of it. Smart homes can make the machines automatic. For example, if the sensor feels the air becoming dry, a smart sprinkler could water your plants by itself. And your toaster could start making breakfast ahead of time or before you get up.
Although not everyone can use 5G networks now, China is trying its best to let everyone use 5G as soon as possible!
