Question

【題目】 If you look at the top of your phone, you’ll usually see a little symbol that says 3G or 4G.【1】 But these symbols will become things of the past after 5G networks fully arrive.

On March 30, 2019, Shanghai vice mayor Wu Qing made the first 5G video call on a Huawei Mate X Smartphone.【2】

About 100 times faster than 4G networks, 5G will let people download(下載) and upload data (數(shù)據(jù)) faster than ever before. But 5G won’t just bring faster mobile internet.【3】

For example, 5G will help to make self-driving cars safer. Today’s self-driving test cars have one problem—lag(延遲). When the car “sees” an obstacle(障礙物), it sends this information to a data center and receives instructions.【4】With this kind of lag, the cars might hit each other because they don’t receive instructions in time. With 5G, this lag will be greatly lowered, making the cars safer.

5G could also be used to help the internet of things(IoT). IoT is a large online network that connects all things and people. Fast internet speeds will be the key to developing this technology. 【5】For example, with IoT, your refrigerator could automatically(自動地) place an order online for eggs when it finds that there are no eggs left inside.

A.Shanghai has also become the first city in China to start testing 5G networks.

B.5G will help us buy eggs quickly.

C.People can use it for many other things as well.

D.However, it takes time to send and receive this information.

E.The “G” is the “generation(代)” of your mobile network.

F.The IoT could be used in a lot of ways.

G.5G networks are much faster than 4G or 3G.

【解析】

這是一篇說明文，文章介紹5G網(wǎng)絡(luò)的開始測試和使用，以及5G網(wǎng)絡(luò)的優(yōu)勢和用途。

【1】

句意：G代表的是你的手機(jī)網(wǎng)絡(luò)的“代”。

根據(jù)前一句的“3G or 4G”可知此處介紹G代表的含義。故選E。

【2】

句意：上海也成為中國第一個開始測試5G網(wǎng)絡(luò)的城市。

根據(jù)“Shanghai vice mayor Wu Qing made the first 5G video call on a Huawei Mate X Smartphone”可知此處介紹上海開始測試5G的情況。故選A。

【3】

句意：人們也可以用它來做其他的很多事情。

根據(jù)前文“5G will let people download and upload data faster than ever before. But 5G won’t just bring faster mobile internet”可知使用5G下載和上傳數(shù)據(jù)比以前更快，但是5G不僅僅是帶來更快地手機(jī)網(wǎng)絡(luò)，此處表達(dá)還可以做別的其他事。故選C。

【4】

句意：然而，需要花時間來傳送和收到這條信息。

根據(jù)前文“it sends this information to a data center and receives instructions”以及下一句“With this kind of lag”可知此處講述傳送信息和收信息有延遲，需要花時間。故選D。

【5】

句意：物聯(lián)網(wǎng)可以有很多方式被使用。

根據(jù)“For example, with IoT, your refrigerator could automatically place an order online for eggs when it finds that there are no eggs left inside”后文舉一個例子講述物聯(lián)網(wǎng)使用的方式。故選F。
