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

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 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.

七、任务型阅读

Good morning, boys and girls. Today I’ll give you a talk about going online.

We know that there are too many net bars（网吧）around us. The Internet makes our lives interesting and enjoyable. Many of us like going online very much because we can learn how to use the computer. We can learn English and read some newspapers and magazines to know more information around us. It can make us clever in playing computer games. Also when we send e-mails to our friends, they can get them right away. It can help us keep in touch with people from all over the world.

But some students spend too much time in playing computer games and some stay in the net bars all day and all night. It takes them too much time to chat online, so they don’t do better 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. I think we should get online with our teachers or parents.

At the same time, if we have lots of free time, we can do some activities after school. We usually have activities from 4:50 to 5:50 in the afternoon. We can play basketball or football. We also have some interest groups in school, such as drawing, singing and dancing. We can go to the English corner on Monday afternoon. I 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.

That’s all! Thank you.

What is 5G?

The “G” in “5G” refers to the generations 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. For example, when you have a video chat with your friend, there is generally a 100 to 200 milliseconds delay with 4G, but 5G will reduce the delay to 1 millisecond(毫秒) or less.

What changes will 5G bring us?

According to the Straits Times, 5G will be able to improve many advanced technologies, such as driverless cars, wearable devices and entertainment.

Does 5G have any disadvantages?

According to the 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 and barely lose signal. 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 specifically designed for 5G that are currently expensive.

You've been learning words since you were a tiny baby. At first, you learned them only by hearing other people talk. Now that you're a reader, you have another way to learn words. What should you do when you come to a word and you think you don't know what it means? 1..

Say it

First sound it out. Then say it to yourself. 2.. Sometimes you know a word in your head but you don't know what it looks like in print. So if you match up what you know and what you read - you have the word!

Use context

If this doesn't work, take the next step: look at the context — the other words and sentences around it. Read this sentence: When it rained, the dog looked for shelter in the doorway. 3.. Rain and in the doorway might give you helpful information.

4.

If the context doesn't help, look at the parts of the word. Does it have any parts you know? These can help you understand what it means. If you don't know the meaning of miner, try looking at parts of the word. You might know that a mine is a place underground where people get coal and other valuable things. A lot of times, -er at the end of a word means "a person who does something". So a miner might be someone who works in a mine.

Look it up

If the three steps above don't work, you can look it up.5. — either a book or online.

Nobody knows the meaning of every word, but good readers know how to understand words they don't know.

A.Use word parts

B.Look at the words

C.It might sound like a word you know

D.You can find the word in a dictionary

E.Following some easy steps can help you

F.If the word shelter doesn't look familiar. look at the words around it
