（2022·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.

Chinese companies lead in global 5G patent applications with Huawei taking the crown, according to a report by IPlytics, an authorized patent data company. Three companies from China were included in the top 10 list of 5G Standards-Essential Patents (SEPs) family owners, Huawei ranked first. ZTE Corp and China Academy of Telecommunications Technology (CATT) grabbed fifth and ninth places.
Chinese companies topped the list with most 5G SEPs applications in communication systems by the end of April 2019, accounting for 34 percent of the world’s total. Chinese tech giant Huawei has taken a leading role by owning 15 percent of SEPs, according to the report “Who Is Leading the 5G Patent Race?”
SG SEPs are patents that any company will have to use when carrying out 5G and no one can avoid them.
Different from 3G and 4G technologies, 5G technology will influence various industries and encourage the appearance of many new products, services and industries.
The automotive sector will most likely be one of the first industries to depend on 5G, which will connect vehicles to other vehicles, roadsides, traffic lights buildings and the Internet according to the report.
“It is 5G that is going to be a huge jump forward for communication systems because only with 5G’s higher bandwidth can a number of applications be more advanced and used by most consumers,” said Nicole Peng, senior director of the market research company Canalys.
As 5G technology has combined various industries and technologies, the number of 5G SEPs rose to more than 60,000 globally by the end of April 2019, the report said.

（2021·江苏盐城·二模）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 these symbols will become things of the past after 5G fully arrives.
On March 30th, 2019, Shanghai vice-mayor Wu Qing made the first 5G video call on a Huawei Mate X smartphone, CGTN reported. Shanghai has also become the first city in China to start testing 5G networks.
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 big change will not only make our mobile Internet faster. It can be used in many other ways as well.
For example, 5G will help to make self-driving cars safer. Today’s self-driving test cars have one problem—lag. When the car “sees” an obstacle (障碍物), it sends this information to a data center and receives instructions. However, it takes time to send and receive 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, according to CNN.
5G could also be used to power the Internet of Things (IOT). This refers to a large online network that connects all things and people. Fast Internet speeds will be the key to developing this technology. For example, with IOT under 5G, your fridge could automatically (自动地) place an order online for eggs when it finds that there are no eggs left inside.
All in all, 5G will shape every type of technology that it touches. And you won’t have to wait too long for that to happen.
41．The writer uses self-driving cars as an example to ________.
A．explain how self-driving cars work B．show us the advantages of self-driving cars
C．warn about the possible dangers of self-driving cars D．explain how 5G’s fast speed can be helpful
42．The underlined word “lag” probably means “________” in Chinese.
A．延迟 B．迷路 C．暂停 D．耗电
43．The fridge is mentioned to ________.
A．describe the importance of IOT B．encourage people to try the new product
C．introduce how to use the Internet of Things D．show 5G would make IOT more powerful
44．Which of the following would be the best title of the passage?
