Question

【題目】Shanghai Begins 5G Trials

Look at the top of your phone. You’ll probably see a 3G or 4G symbol. The G stands for the generation of your mobile network. Now, the age of 5G is coming.

On March 30, Shanghai vice-mayor Wu Qing made the first 5G video call on a Huawei Mate X smart phone. CGTN reported Shanghai has also become the first city in China to start testing 5G networks.

5G is about 100 times faster than 4G. It will bring faster mobile Internet, but people can also use it for many other things, such as self-driving cars. There is a big area of discussion about self-driving cars, which we’ve all seen a lot of news about, but we haven’t seen a lot of real cars driving themselves on the streets because it is not safe enough. However, 5G is so much faster, it could allow cars to talk to each other in time, so they can know clearly when other cars are switching lanes, going off the road, passing another car, going too fast and so on. This will help avoid accidents. So probably there will be more self-driving cars in the near future with the help of 5G.

【解析】

文章主要講上海開始進行5G試驗，詳細(xì)介紹了5G的優(yōu)勢及5G技術(shù)在無人駕駛領(lǐng)域的應(yīng)用。

【1】細(xì)節(jié)理解題。根據(jù)第一段“CGTN reported Shanghai has also become the first city in China to start testing 5G networks.”可知，上海市是第一個測試5G網(wǎng)絡(luò)的城市，故選B。

【2】細(xì)節(jié)理解題。根據(jù)第三段“5G is about 100 times faster than 4G.”可知5G比4G快100倍，故選A。

【3】細(xì)節(jié)理解題。根據(jù)第三段最后一句“So probably there will be more self-driving cars in the near future with the help of 5G.”可知，5G提高自動駕駛汽車的安全性，故選D。
