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

4.Which of the following is NOT true according to the passage?

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

B.Self-driving cars will become safer because of the use of 5G.

C.Using 5G to download something doesn't take any time at all.

D.5G can make people download an entire HD movie in a second.

If you look at the top of your phone, you will usually see a little symbols that says 3G or 4G. The G means "generation" of your mobile network. But these symbols will become things of the past after 5G networks fully arrive.

On March 30, Shanghai vice-mayor (副市长) Wu Qing made the first 5G video call on the Huawei Mate X Smartphone. Shanghai has also become the first city in our country to start testing 5G networks.

More and more people started to learn about 5G because it has many advantages. 5G will let people download and upload the data (上传数据) faster than before. 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 take time to send the information and the receiving instructions. They can't react in time. With the help of 5G, this can be greatly improved.

People could also use 5G to power the Internet of Things (IOT 物联网). It's a large online network that connects all things and people. Fast Internet speed will be the key to developing this technology.

5G is on the way. It will lead us to a new world. Are you ready?

Each mobile network generation is faster and more powerful than the one before it. 1G let us talk to each other. 2G let us send messages. 3G gave us data（数据）and the Internet. And 4G made all of these things faster. What's special about 5G?

5G has a very short delay between sending and receiving information. Now, 4G takes about 100 to 200 milliseconds（毫秒）to send and receive data. But 5G will get it down to 1 millisecond or less-this is almost real-time.

'This big change will not only make our mobile Internet faster，but also deeply change our lives. Read on to find out how.

5G + entertainment（娱乐）

5G networks are about 100 times faster than 4G. This means you can download a movie in seconds using 5G.

Also, virtual reality（VR）games will become more popular with 5G. The short delay of 5G will make the games feel even more real.

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

九年级英语阅读单选中等难度题查看答案及解析

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.

1.According to the passage, what can 3G do?

A.People can send messages. B.People can talk to each other.
