Big telecommunications companies such as Huawei, Samsung and Qualcomm have announced their latest fifth generation (5G) products. They have also announced that 5G technology would be widely used by 2020, causing some experts to say the “5G epoch” is coming. Yet, when reporting about 5G, many reporters only described it as a “much faster” technology than 4G. As a result, what people know about 5G is that they could “download a movie within one second”.
Actually, 5G technology has many more advantages than 4G besides the speed. It can be used for at least two purposes-for connecting everything and removing delays(消除网络延时).
Connecting everything is one of the strongest functions of 5G. It makes the Internet Things possible. Take driverless smart cars as an example. 5G technology can connect all parts of a transportation system including traffic lights, CCTV cameras and cars to build up perfect coordination(协调). In this way, these cars can avoid obstacles(障碍) and move on driving routes, which will help improve self-driving technology.
And removing delays might be useful especially in online games. Even long after 4G technology was introduced, players still worried about losing games because of low speed. This problem can be solved with 5G technology, because it will make sure of continuous high speed.
And for those people who think that 5G costs will be very high, they need not worry. Compared with 4G macro base station, a 5G macro base station can provide service to more users. Factories can produce more macro base stations to allow more people to use. The more users, the lower cost. Therefore, 5G technology won’t cost as much as they thought.

A.技术 B.时代 C.设备 D.讯号

A.it makes the self-driving car run much faster

3.Factories can produce more macro base stations so that ________.
A.people can pay less for 5G B.5G can be compared with 4G
C.the “5G epoch” can come sooner D.few people can enjoy the 5G technology
4.According to the passage, we can know that ________.
A.people know a lot about 5G
B.5G is much faster but more expensive than 4G
C.connecting everything is the strongest function of 5G
D.online game players can enjoy continuous high speed of 5G
5.What’s the main idea of the passage?

C.5G technology costs less with higher speed. D.5G technology is more than about high speed.
