Your Internet experience is ruined when the net speed is too slow — it takes so long to open a web page and the reality shows you’re watching stops every few minutes. That can be very annoying.

But it could be a thing of the past. On June 3, the Ministry of Industry and Information Technology announced that China’s major telecom carriers(电信公司) would start to provide 5G services.

1 What is 5G?

The “G” in “5G” refers to the generation of mobile network technologies. 1G let us talk to each other, 2G let us send messages, 3G gave us mobile data and the Internet, and 4G made all of these things faster.

Now 5G promises much faster data download and upload speeds, and more stable connections. This means that you will be able to download an entire HD movie in seconds and only experience a short delay(延迟) between sending and receiving data.

2 What changes will 5G bring us?

With a 5G network, the short delay in information exchange will allow driverless cars to run more safely. Meanwhile, 5G-enabled wearable devices(设备) will be of great use in hospitals. Besides, VR games will become more popular with 5G. The short delay of 5G will make the games feel even more real.

3What are the disadvantages of 5G?

According to the BBC, __________, it will not be perfect.

For one thing, 5G will not“travel” far. On 4G networks, you can be 10 kilometers away from the nearest transmission base and hardly lose signal(信号). But 5G will only cover about 300 meters. And in order to use 5G, we will have to buy new products especially designed for 5G that are expensive at present. All in all, there is still much to be done before 5G’s popularization.

1.“G” in “5G” refers to ___________.

A.the speed of the Internet B.the generation of the technology

C.the delay in information exchange D.the game on the smart phone

Your Internet experience will be influenced, when the net speed is too slow-it takes so long to open a web page and the reality show you are watching stops every few minutes. That can be very unpleasant. But it could be a thing of the past after 5G networks fully arrive.

The "G" stands for the "generation" of your mobile network. 1G let us talk to each other, 2G let us send messages, 3G gave us mobile data (数据) and the Internet, and 4G made all of these things faster. About 100 times faster than 4G networks, 5G will let people enjoy a faster Internet speed than ever before. This means that you will be able to download (下载) an HD movie in seconds with a short delay (延迟). But 5G won't just bring faster mobile Internet. People can use it for many other things as well.

With a 5G network, the short delay in information exchange will allow driverless cars to run more safely, as they will be able to communicate in real time and avoid unexpected dangers. At the same time, 5G -enabled wearable devices (设备) will keep doctors know what is happening to their patients and let them know in time if there is something wrong. Besides, VR games will become more popular with 5G. The short delay of 5G will make the games feel even more real.

According to BBC, though 5G will make our lives more convenient, it will not be perfect. For one thing, 5G will not travel "far". On 4G networks, you can be 10 kilometers away from the nearest transmission base (传输基站) and seldom lose signal (信号). But 5G will only cover about 300 meters, meaning that we will need more transmitters so that we can get signals. And in order to use 5G, we will have to buy new products exactly made for 5G that are expensive now.

Good morning, class!

We know that there are too many net bars around us. The Internet is popular and it makes our lives colorful. Many of us like going online very much because we can learn how to use the computer and get more information from the Internet. We can learn English. We can read some good newspapers and magazines. It can make us clever in playing computer games. We can send E-mails to our friends quickly. We can chat(聊天) freely online with our friends. It can help us get in touch with people from all over the world.

But some students spend too much time in playing computer game and some stay in the net bars all day and all night. Teenagers even get to have boyfriends or girlfriends online. They write too many letters to each other. It takes them to much time to chat online so they do worse and worse in their lessons and they don’t study well any more. I think we mustn’t get online when it is time for us to study. We can do it in summer or winter holidays. We should get online with adults(成人)--our teacher or parents.

At the same time, if we have lots of free time, we can do some out-of-class activities at school. We usually have activities from 4:50 to 5:50 in the afternoon. We have different kinds of activities. If you are interested in sports, you can play basketball or football. We can go to the English Corner. We can practice talking in English there. We hope we can spend more time on our subjects or on such activities that we can learn a lot from and less time on the Internet.

Thank you for listening to me. That’s all.
