Question

【题目】 Do you know 5G? It is the fifth generation (代) 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. 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 our lives. Read on to find out how.

5G+entertainment (娱乐)

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.

A.We can download a movie faster with 5G.

B.Human drivers can send signals at traffic lights.

C.The plants can water themselves by a smart sprinkler with 5G.

D.5G is faster and more powerful than 4G.

【5】What's the main idea of the passage?

A.Mobile phone users can use 5G networks.

B.Each mobile network generation has their own advantages.

C.5G will change our lives in many ways.

D.5G will bring us safer self-driving cars.

Answer 1

【答案】

【1】B

【2】A

【3】D

【4】B

【5】C

【解析】

本文介绍了5G网络，是指第五代移动通信网络，5G网络不仅让网络速度更快，也改变了我们的生活。比如5G娱乐，5G交通和智能家庭。

【1】

细节理解题。根据第二段第一句“China just issued commercial licenses (发放商用牌照) for 5G on June 6.”可知，6月6日中国将发放商用牌照。故选B。

【2】

词义猜测题。根据第四段“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.”可知，5G在接收发送信息之间只有非常短的延迟，4G网络用100-200毫秒收发数据，但是5G网络用不了一毫秒就能收发信息，真的很快了。所以只有很短的延迟。故选A。

【3】

细节理解题。根据三个黑色的小标题，在娱乐，交通，智能家庭方面都能改变人们的生活。 故选D。

【4】

细节理解题。根据第一个黑色小标题“5G networks are about 100 times faster than 4G. This means you can download a movie in seconds using 5G.”可知，下载电影用5G网络会更快。A正确；根据第二个黑色小标题第二句“These cars can send signals (信号)to each other.”可知，车辆之间可以发送信号。不是司机，故B不对；根据最后一句话“And if its sensor feels the air becoming dry, a smart sprinkler could water your plants by itself.”可知，传感器感到空气干燥的时候，智能喷洒器就能自动浇灌植物。C争取；D选项即为文章内容5G网络更快，更强大。故选B。

【5】

文章大意题。文章讲解了5G网络的便捷，同时指出在娱乐，交通以及智能家庭方面给人们生活带来的改变。故选C。
