1 . In movies, you might see cars that can drive by themselves, you tell them where you want to go, and they take you there as fast as possible. With 5G, cars like this may soon come into our real life because 5G can connect many different smart devices (智能装置) to one network (网络).

Finland’s “robot buses” are a good example. Telecom company Nokia builds 5G transmitters (信号发射器) along a 1 kilometer road. These transmitters are able to control the buses, making them driverless, according to Raconteur Media.

There are also 5G roads. These roads will have many 5G transmitters. They can give you smart services, such as telling you where the nearest oil station is. People can also use them to control traffic on the roads. “People will use a road network in real time, controlling traffic light, traffic numbers through computer programs,” said a scientist.

In south Korea, a subway station builds a smart system. This system has a 3D map, sensors (传感器) and an advanced (先进的) camera system that make the station more useful and safer, according to Arirang News.

And of course, there are driverless cars. These cars can send signals (信号) to each other. They also “talk” to traffic lights and road sensors. 5G will let these car drive more safely because they can communicate (交流) with each other, as well as with traffic lights and road sensors.

2 . Take a look at your parents’ mobile phones. Can you see a small “5G” at the top? Do you know what it is? 5G means “5th generation mobile network (第五代移动通信技术)”.

Each mobile network generation is faster and more powerful than the one before it. In 1980s, with 1G, we made phone calls for the first time. Around ten years later, 2G let us send messages. Then in 2000s, using the Internet, listening to music and sending emails appeared in people’s life for 3G. Later, we could watch films and even buy things in 2010s with 4G. To our surprise, 5G is coming now.

Do you have online classes at home? With 5G, you can have classes outside your home. The class can go as well as the ones you have at home. Students from poor areas can have the chance to study just like you do.

In some movies, you might see cars that can drive by themselves—you tell them where you want to go, and they take you there as fast as possible. With 5G, cars like this may appear in our life. It makes self-driving cars safer. These cars can send messages to each other. They can also “talk” to traffic lights. 5G will make cars move even faster than human drivers.

5G networks are about 100 times faster than 4G. This means you can download (下载) a movie in seconds using 5G, and makes your video calls clearer. What’s more, VR games will become more popular with 5G. It will make the games feel even more real.

All in all, 5G will change the way people live and make our life more comfortable and convenient than ever before. You won’t have to wait too long to enjoy it. Now you can buy a new mobile phone to use 5G networks. 5G phones cost about 8,000 yuan right now. But experts say that about one and a half years later, the price could go down to around 2000 yuan. Why not try 5G?

3 . 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 may drive you crazy. But it could be a thing of the past. Because 5G services are coming.

What is 5G? What difference will it really make to our lives? The “G” in “5G” refers to the generations（代）of mobile network technologies. 1G let us talk to each other, 2G let us send messages, 3G gave us mobile data（数据）and the Internet, and 4G made all of these things faster. Now 5G promises much faster data download and upload speeds. This means that you will be able to download a movie in seconds and only experience a short delay（延迟）between sending and receiving data.

5G will be able to improve many new technologies. With a 5G network, the short delay in information exchange will allow driverless cars to run more safely. And 5G can help doctors know the health condition 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 kilometers away from the nearest transmission base（发射站）and hardly ever lose signals（信号）. But 5G will only cover about 300 meters, meaning that we will need more transmission bases. And in order to use 5G, we will have to buy new products that are quite expensive now.

4 . 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 behind Korea’s Samsung. It has also become the world’s largest supplier (供应商) of 5G.

But recently, Huawei faced some difficulties. The U. S. government ordered a ban (禁令) on its sales in America. American officials said Huawei gave information that it collected to the Chinese government. At the same time, the U. S. government planned to stop selling parts and services to Huawei, which was believed that Huawei's business would be hurt.

“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 founder and president said. “The ban from the U. S. 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 £4,000 at the beginning, but now it has become a $100 billion company. The experience was not as romantic (浪漫的) as you imagine.”

Facing the ban of the U. S., 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 (电信设备) supplier, selling in 170 countries. It may beat Samsung as the largest smartphone maker in the near future.

5 . 阅读下面的短文,用括号内所给词的适当形式填空,必要时可加助动词。

What is 5G? It is the     1     (five) generation of mobile network technology. China’s telecom companies     2     (be) able to offer 5G networks for mobile phone users since 2019.

Do you know the development of mobile network technology? 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     3     (message). 3G gave us data and the Internet. And 4G     4     (make) all of these things faster.What’s special about 5G?

5G has a very short delay (延迟) between sending and receiving information. Now, 4G takes about 100 to 200 milliseconds(毫秒)     5     (send) and receive data. But 5G will get it down to I millisecond or less—this is almost real-time.

This big change will not only make our mobile Internet faster,but also     6     (deep) change our lives. Read on     7     (find) out how.

5G+entertainment

5G networks are about 100 times faster than 4G.This means you can download a movie in seconds by     8     (use) 5G. Also, virtual reality (VR) games will become more popular with 5G. The short delay of 5G will make the games feel even     9     (much) real.

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,if the sensor feels the air becoming dry, a smart sprinkler(洒水器) could water your plants by     10     (it).

6 . If you look at the top of your phone, you will usually see a little symbol that says 3G or 4G. The “G” stands for the “generation”（代）of you mobile network（网络）. But these symbols will mean（意味着）that things of the past after 5G network fully arrives.

The 5G mobile network is 100 times faster and has 1, 000 times more capacity（容）compared with the 4G mobile network.

In recent years, China pays great attention to the commercial（商业）use of 5G and tries to build the infrastructure（基础设施）for a 5G network. On March 30th, 2019, Shanghai vice-mayor（副市长）Wu Qing made the first 5G video call on a Huawei Mate 10 smartphone, CGTN reported. Shanghai is also the first city in China to start testing 5G network.

5G will let people download and upload data（数据）faster than ever before. But 5G will not just bring faster mobile Internet. People can use it for many other things, too. For example, 5G will help to make self-driving cars safer. Today’s self-driving test cars has one problem—the lag（滞后）. When the car “sees” an obstacle, it sends this information to a data center and gets instructions（指示）.

However, it takes time to send and get this information. With this kind of lag, the cars might crash（撞击）because they don’t get instructions in time. With 5G, this lag will be greatly reduced（减少）and make the cars safer.

5G could also be used to make the Internet of Things（IOT）stronger. This refers to a large online network that connects（联系）all things and people. Fast Internet speeds（速度）will be the key to developing this technology（技术）. For example, with the Internet of Things（IOT）, your fridge could order eggs online when it finds there are no eggs left inside. How amazing!

1. We can learn from the story that            .

A．China will pay little attention to the use of 5G

B．there will be no difference between phones

C．we can now buy self-driving cars cheaply

D．the 5G mobile network is much faster than the 4G network

2. The writer uses self-driving as an example to         .

A．make us understand how self-driving cars work

B．show us how fast self-driving cars are

C．tell us the possible dangers of self-driving cars

D．tell us how 5G’s fast speed（速度）can be helpful

3. The underlined word “obstacle” in Para. 4 means            in Chinese.

A．障碍物

B．困难

C．目标

D．警告

4. According to the story, the IOT is          .

A．a robot that can do housework

B．a large online store where you can buy anything you want

C．a large online network that connects everything and everyone

D．a kind of fridge which has IOT technology.

7 . We have recently heard some interesting ways that 5G technology might change our lives in the future. 5G promises Internet speeds between 50 to 100 times faster than 4G system. Such improvements are sure to be popular for 5G users worldwide. While it is stated only in some few areas of the United States this year, much of the rest of the world is not expected to receive this service until 2023.

One project Britain, though, is already testing this superfast technology, but not on humans. Instead, the experimental subjects （实验对象） are cows. The system connects the animals to 5G in order to automate （使自动化） the milking process.

The project was developed by American technology company Cisco Systems. Testing areas were set up at farms in England. The cows are equipped with 5G-connected devices （设备） with a milking system. The system uses sensors （传感器） and machine leaning to fully automate the process.

System designers say technology starts to work after a cow feels ready to be milked and walks towards an automatic gate. The device can recognize each cow. It can put the equipment to the right body position for milking. During the process, machines offer food for the cow as a reward.

One of the test areas is in the town of Shepton Mallet in southwest England. There, about 50 of the farm’s 180 cows are fitted with 5G ear sensors. Project officials say the devices are not bad for the cows and the sensors help farmers find any health problems.

Duncan Forbes, the project leader, told Reuters that so far, he thinks the project shows the farm’s cow operations can be greatly improved with 5G technology.

Forbes added that the experiment provides strong evidence that 5G technology can be widely used in the future “not just on farms, but in other places across the country.”

1. What do we know about 5G technology from the first two paragraphs?

A．It has changed our lives.	B．It has more users than 4G.

8 . 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.

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 ore 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.
