【題目】

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.延遲B.迷路C.暫停D.耗電

【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
