Question

【題目】 Do you know 5G? It is the fifth generation (代) of mobile network technology. These new networks are coming.

China just issued commercial licenses (發(fā)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 (娛樂)

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 (信號(hào))to each other. They also talk to traffic lights and road sensors (傳感器). 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 (自動(dòng)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】

本文介紹了5G網(wǎng)絡(luò)，是指第五代移動(dòng)通信網(wǎng)絡(luò)，5G網(wǎng)絡(luò)不僅讓網(wǎng)絡(luò)速度更快，也改變了我們的生活。比如5G娛樂，5G交通和智能家庭。

【1】

細(xì)節(jié)理解題。根據(jù)第二段第一句“China just issued commercial licenses (發(fā)放商用牌照) for 5G on June 6.”可知，6月6日中國(guó)將發(fā)放商用牌照。故選B。

【2】

詞義猜測(cè)題。根據(jù)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在接收發(fā)送信息之間只有非常短的延遲，4G網(wǎng)絡(luò)用100-200毫秒收發(fā)數(shù)據(jù)，但是5G網(wǎng)絡(luò)用不了一毫秒就能收發(fā)信息，真的很快了。所以只有很短的延遲。故選A。

【3】

細(xì)節(jié)理解題。根據(jù)三個(gè)黑色的小標(biāo)題，在娛樂，交通，智能家庭方面都能改變?nèi)藗兊纳�活�?/span> 故選D。

【4】

細(xì)節(jié)理解題。根據(jù)第一個(gè)黑色小標(biāo)題“5G networks are about 100 times faster than 4G. This means you can download a movie in seconds using 5G.”可知，下載電影用5G網(wǎng)絡(luò)會(huì)更快。A正確；根據(jù)第二個(gè)黑色小標(biāo)題第二句“These cars can send signals (信號(hào))to each other.”可知，車輛之間可以發(fā)送信號(hào)。不是司機(jī)，故B不對(duì)；根據(jù)最后一句話“And if its sensor feels the air becoming dry, a smart sprinkler could water your plants by itself.”可知，傳感器感到空氣干燥的時(shí)候，智能噴灑器就能自動(dòng)澆灌植物。C爭(zhēng)��；D選項(xiàng)即為文章內(nèi)容5G網(wǎng)絡(luò)更快，更強(qiáng)大。故選B。

【5】

文章大意題。文章講解了5G網(wǎng)絡(luò)的便捷，同時(shí)指出在娛樂，交通以及智能家庭方面給人們生活帶來的改變。故選C。
