Question

【题目】 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.

【1】The underlined word “epoch” in Para 2 means ________.

A.技术B.时代C.设备D.讯号

【2】5G technology can help improve self-driving technology because ________.

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

B.it helps to connect the cars with the Internet

C.it helps the cars avoid obstacles and move on driving routes

D.it helps the cars control the traffic lights and CCTV cameras

【3】Factories can produce more macro base stations so that ________.

A.people can pay less for 5GB.5G can be compared with 4G

C.the “5G epoch” can come soonerD.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?

A.The “5G Epoch” is coming.B.The latest 5G products have been invented.

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

Answer 1

【答案】

【1】B

【2】C

【3】A

【4】D

【5】D

【解析】

本文主要讲了人们对5G的了解甚少，只知道它的速度快。事实上除了速度外，5G还有更多的优势。它至少可以用于两个目的——连接所有的东西和消除延迟。

【1】词句猜测题。根据上文They have also announced that 5G technology would be widely used by 2020, causing some experts to say the “5G epoch” is coming. 他们还宣布，到2020年，5G技术将得到广泛应用，导致一些专家认为…即将到来。由2020年广泛使用5G，可知5G的时代来了，故选B。

【2】细节理解题。根据上文In this way, these cars can avoid obstacles(障碍) and move on driving routes, which will help improve self-driving technology. 通过这种方式，这些汽车可以避免障碍，并在驾驶路线上行驶，这将有助于提高自动驾驶技术。故选C。

【3】细节理解题。根据上文Factories can produce more macro base stations to allow more people to use. The more users, the lower cost. 工厂可以生产更多的宏基站，让更多的人使用，用户越多，成本越低。故选A。

【4】推理判断题。A. people know a lot about 5G.根据上文“when reporting … only described it as a “much faster” technology than 4G, …5G is that they could “download a movie within one second”.可知人们对5G的了解甚少，只知道它的速度快。所以此项说法错误，排除A；B. 5G is much faster but more expensive than 4G.根据上文 5G technology won’t cost as much as they thought. 5G技术的成本不会像他们想象的那么高。所以此项说法错误，排除B；C. connecting everything is the strongest function of 5G. 根据上文Connecting everything is one of the strongest functions of 5G. 连接一切是5G最强的功能之一。所以此项说法错误，排除C；D. online game players can enjoy continuous high speed of 5G. 根据上文This problem can be solved with 5G technology, because it will make sure of continuous high speed. 这个问题可以用5G技术解决，因为它将确保连续高速。可知此说法正确，故选D。

【5】主旨大意题。根据上文Actually, 5G technology has many more advantages than 4G besides the speed. 事实上，5G技术除了速度外，还有更多的优势。通读全文，可知主要讲了5G除了速度快之外，还有很多优势，故选D。

在做细节理解题时一定要找到文章中的原句，和题干进行比较，再做出正确的选择；在做推理判断题时不要以个人的主观想象代替文章的事实，要根据文章事实进行合乎逻辑的推理判断。
