Question

【题目】

If you look at the top of your phone ,you'll usually see a little symbol that says 3G or 4G. The "G" stands for the "generation" of your mobile network.But these symbols will become things of the past after 5G fully arrives.

On March 30th, 2019, Shanghai vice-mayor Wu Qing made the first 5G video call on a Huawei Mate X smartphone, CGTN reported.Shanghai has also become the first city in China to start testing 5G networks.Monaco became the first country in Europe to use a next-generation 5G mobile phone network based on technology from Chinese company Huawei.

It sounds obvious, but it’s important to understand just how much faster 5G is compared to current 4G speeds. 5G will not only be many, many times faster than your existing connection, it will be greatly faster than the broadband connection you have at home.

Now, 4G takes about 100 to 200 milliseconds* to send and receive data.But 5G will get it down to 1 millisecond or less.This big change will not only make our mobile Internet faster. It can be used in many other ways as well.

For example,5G will help to make self-driving cars safer.Today's self ﹣ driving test cars have one problem ﹣ lag.When the car"sees"an obstacle*, it sends this information to a data center and receives instructions. However, it takes time to send and receive this information. With this kind of lag, the cars might crash because they don't receive instructions in time. With 5G, this lag will be greatly lowered, making the cars safer,according to CNN.

5G could also be used to power the Internet of Things (IOT). This refers to a large online network that connects all things and people.Fast Internet speeds will be the key to developing this technology. For example, with IOT under 5G, your fridge could automatically* place an order online for eggs when it finds that there are no eggs left inside.

All in all, 5G will shape every type of technology that it touches. And you won't have to wait too long for that to happen. Though we’ve seen a lot of positive progress just in the last year, we still have a long way to go before 5G is anywhere near as common as 4G is right now.

【1】From Paragraph ②, we can know that _______.

A.5G is widely used in Shanghai

B.it took lots of efforts to test 5G

C.China and Monaco is working on its 5G networks

D.5G would make it possible to take videos

【2】The underlined word "lag" probably means " _______" in Chinese.

A.延迟B.迷路C.暂停D.耗电

【3】The fridge is mentioned to _______.

A.describe the importance of IOT

B.encourage people to try the new product

C.introduce how to use the Internet of Things

D.show 5G would make IOT more powerful

【4】Which of the following would be the best title of the passage？

A.Can 5G Go Far？

B.How is 5G Changing Our Life？

C.5G is on the Way

D.China is Leading the World in 5G

Answer 1

【答案】

【1】C

【2】A

【3】D

【4】C

【解析】

本文主要介绍了5G的优点和缺点。

【1】

细节理解题。根据第2大段“Shanghai has also become the first city in China to start testing 5G networks.Monaco became the first country in Europe to use a next-generation”上海成为中国第一个开始测试5G网络的城市，摩洛哥成为欧洲第一个使用5G网络的国家。可知，中国和摩洛哥正在建设5G网络。故选C。

【2】

词义猜测题。根据第5大段“With this kind of lag, the cars might crash because they don't receive instructions in time.”用这种lag，汽车可能因为不能及时收到指示而撞车。可知，lag指延时的意思。故选A。

【3】

推理判断题。根据第6大段的中心句“5G could also be used to power the Internet of Things (IOT)”5G可以为IOT提供动力。可知，冰箱的举例是为了说明5G在生活中能为IOT助力，使IOT变得更强大。故选D。

【4】

最佳标题题。根据第7大段“Though we’ve seen a lot of positive progress just in the last year, we still have a long way to go before 5G is anywhere near as common as 4G is right now.”尽管去年我们看到了很多积极的进展，但要让5G像现在的4G一样普及，我们还有很长的路要走；再根据第1大段“But these symbols will become things of the past after 5G fully arrives.”但是当5G完全到来时，这些标志都将会成为过去。可知，本文主要讲述了5G时代即将到来。故选C。
