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（代）”of your mobile network. But these symbols will become things of the past after 5G networks fully arrive.

On March 30th,2019, Shanghai vice-mayor（副市長(zhǎng)）Wu Qing made the first 5G video call on a Huawei Mate X smart phone, CGTN reported. Shanghai has also become the first city in China to start testing 5G metworks.

About 100 times faster than 4G networks. 5G will let people download and upload data faster than ever before. But 5G won’t just bring faster mobile Internet. People can use it for many other things as well.

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 the information to a data center and receives instructions. However, it takes time to send and receive information. With this kind of lag, the cars might crash because they don’t receive instructions in time. With 5G, this lag will be great lowered , making the cars safer, according to CNN.

5G could also be used to power the Internet of Things（IoT 物聯(lián)網(wǎng)）. This refers to a large online network that connects all things and people. Fast Internet speeds will be the key to develop this technology.

The IoT could be used in a lot of ways. For example, with IoT, your refrigerator could automatically place an order online for eggs when it finds that there are no eggs left inside.

閱讀短文根據(jù)短文內(nèi)容判斷句子正誤。正確的涂A錯(cuò)誤的涂B

Dear Dr Know,

My mom decides and cares about nearly everything in my life-my clothes, my after-school classes, even who I hang out with. I know she does these because she loves me, but it's really annoying and it makes me stressful, What can I do?

Mike

Dear Mike,

I can understand you.

You're right when you say that she does these things because she loves you. It's quite possible that she does them because she still regards you as a young child.

But on the other hand, as you are getting older, you will need to be more independent. Your mom might not want to hear this. Why not sit down and have a talk with her and explain that you want to exercise your independence more? Tell her that you can deal with some things on your own, and you will ask her for help when needed. Hope my suggestions helpful.

Dr. Know

1.Mike tells Dr. Know his happiness because of his mom' s love.

2.Dr Know can't understand Mike's feelings.

3.Mike wants to make some decisions by himself.

4.Dr. Know thinks communicating is a good way to solve Mike's problem.

5.Mike’ s mom does few things for him in the family.
