What is 5G? It is the fifth generation of mobile network technology. In the past, 1G let us talk with each other. 2G let us send messages. 3G gave us the Internet. And 4G made all of these things faster. What's special about 5G?

5G + entertainment

5G networks are about 10 times faster than 4G. This means you can download a movie in seconds using 5G. Also, VR games will become more popular with 5G.　 5G will make the VR games even more real.

5G + smart home

5G also makes the Internet of Things（物联网）possible. Smart home is part of it. For example, your bread maker could make breakfast by itself after your alarm rings. And if the air in your room is too dry, a smart sprinkler could water your plants by itself when you are not at home.

So you just need to buy a new mobile phone to use 5G. But a 5G phone costs about 8,000 yuan right now. It is said that about one year from now, the price could go down to around 2,000 yuan.

1.________

九年级英语信息归纳中等难度题查看答案及解析

You might have noticed that sometimes, when you're playing mobile games or making a video call, the picture suddenly freezes (卡顿) because the network speed is too slow. When you try to download a movie on your phone, it seems to take forever.

These annoying things will soon become things of the past, as China just issued commercial licenses (发放商业牌照) for 5G networks on June 6. This means that China's telecommunications (电信) companies will be able to offer 5G network speeds for mobile phone users.

The "G" stands for generation (代). 1G let us talk to each other, 2G let us send messages, 3G gave us mobile data and Internet, and 4G made all of these things faster. So what will 5G bring?

First of all, 5G is so fast that it will allow us to download an entire HD movie in a second. The delay (延时) between sending and receiving data will be shortened. Now, 4G takes about 100 to 200 milliseconds (毫秒), while humans have a reaction time of about 200 to 300 milliseconds. But 5G will get the delay down to 1 millisecond or less, which is almost real-time.

Because of this increase in speed, it will possible to create and use new kinds of technology. Robots will be used to do operations because doctors will be able to control them from somewhere else without any delay. Self-driving cars will be able to drive more safely because they can smoothly communicate with other cars, traffic lights and road sensors (传感器). 5G also makes the Internet of Things (IOT, 物联网) possible.

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.

1.From the first paragraph that ________.

A.people can't download a movie at all on the phone

B.making a video call is impossible for phone users

C.sometimes the network speed is too slow to use

D.mobile games can't be downloaded on the phone

2.What happened on June 6 according to the passage?

A.China just gave commercial licenses officially for 5G networks.

B.Every mobile phone user could improve the network speed.

C.Most mobile phone users didn't use 4G anymore.

D.All the mobile phones are much cheaper than before.

3.The underlined word "them" refers to "___________".

A.operations B.robots C.5G phones D.speeds

A.5G will make people's life much easier and more convenient.

When was the last time you used a phone booth on the street? With the rise of mobile phones, they have become something out of date. But Shanghai is trying to bring new life to the old phone booths by turning them into mini-libraries.

Shanghai plans to divide 263 phone booths in Xuhui District into six new types. One type will each offer 60 books for people to read or borrow. A second type will allow users to listen to audiobooks and even record their own voices. A third type will become “Celebrity Exhibition Halls (名人亭)”, showing old photos and works of famous artists like Ba Jin and Zhang Leping.

Shanghai is not the only city trying to save the old phone booths. The British care about them even more, since the red phone booths have long been a part of the country’s identity*. The world’s first phone booth was built in the 1880s in Germany. But in the 1930s the UK painted them red and made them a special attraction in cities.

In recent years the country has come up with many ideas to help phone booths stay useful. The UK company British Telecom has added screens and free WiFi to some booths.

Since 2009, more than 1,500 phone booths have been turned into flower shops, mini-cafés, art museums and even shower rooms, according to the Sina News. Besides, the town has made it into a museum to show visitors the local history. Today the phone booths is filled with photographs, ancient jewelry, and paintings, which anyone can stop in to admire. Every three months, they will change for a new theme.

Maybe in the future phone booths will become city attractions once again, but in a more creative way.
