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(lè)）

5G networks are about 100 times faster than 4G. This means you can dowload 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.

【1】What does the underlined word “delay” in Paragraph 4 probably mean in Chinese?.

A.延時(shí)B.暫停C.斷開(kāi)D.卡頓

【2】5G will change people’s lives in many ways EXCEPT _________.

A.entertainmentB.transportationC.smart homesD.health

【3】Which of the following is NOT true according to the passage?

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.

【4】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】A

【2】D

【3】B

【4】C

【解析】

文章主要介紹了5G給我們的生活帶來(lái)的變化：娛樂(lè)，交通和智能家居。

【1】

詞義猜測(cè)題。根據(jù)文中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. 5G在發(fā)送和接收信息之間有很短的……�，F(xiàn)在，4G發(fā)送和接收大約需要100到200毫秒數(shù)據(jù)。但是5G將把它降低到1毫秒或更少這幾乎是實(shí)時(shí)的�？芍�這里的delay指的是“延時(shí)”，故選A。

【2】

細(xì)節(jié)理解題。根據(jù)文中This big change will not only make our mobile Internet faster, but also deeply change our lives. Read on to find out how.以及文中的介紹5G+entertainment，5G+transportation，5G+smart homes可知，這里沒(méi)有介紹5G對(duì)健康的改變，故選D。

【3】

細(xì)節(jié)理解題。根據(jù)文中5G will also bring us safer self-driving cars. These cars can send signals(信號(hào)）to each other. 5G也將給我們帶來(lái)更安全的自動(dòng)駕駛汽車。這些汽車可以互相發(fā)送信號(hào)�？芍�并不是人類司機(jī)可以在紅綠燈處發(fā)出信號(hào)。所以是錯(cuò)誤的，故選B。

【4】

最佳標(biāo)題題。根據(jù)文章的開(kāi)頭Do you know 5G? It is the fifth generation(代）of mobile network technology. These new networks are coming.以及整個(gè)文章的理解可知，主要是介紹的是5G給我們的生活帶來(lái)的一些變化，并列舉例在娛樂(lè)，交通以及智能家居方面的具體的改變可知，文章主要是介紹5G對(duì)我們生活的改變的，故選C。
