1 . Technology is developing fast and it has become an important part of our life. Then what will the world be like in the future?
3-D food will be both delicious and nutritious (有营养的). We can use 3-D printers to print some basic materials. And we can go further. Scientists believe that we just need to turn on a printer in the kitchen and then we can enjoy our favorite food whenever we like.
5G network will allow many more people to get information. Big companies like China Mobile and China Unicom will start to offer 5G. It is said that 5G promises download speed 10 to 20 times faster than 4G. For example, we can download a film within just 1 second. But with 4G network, it takes a few minutes. There will be much bandwidth (带宽) and we can get unlimited information.
Underwater cities will provide more space. The earth is becoming more and more crowded. We may turn to underwater homes, which will be built as low as 15 kilometers below the sea. And the different temperatures at the different depths of the sea can be used to provide power for the homes.
Space tour will be a piece of cake. For us common people on the earth, the dream of travelling around space will come true. In the coming years, spacecraft will be as popular as buses, trains and planes. We can leave our home and enter space to take an adventure. And even we will get used to living there.

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. 4G is the forth 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. 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 Smart phone. 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?

3 . China has changed rapidly over the past 72 years. Recently, we asked some students to share their feelings about the rapid changes and developments（发展）of China. Here are some of their answers online:
A few months ago, our school visited the China International Import Expo. In the 5G hall, I was impressed by how quickly people could download（下载）videos. It took just seconds. It was amazing! I also saw a robot with sensors（感应器）in all parts of its body. With the help of 5G technology, the robot can do the same things as people do. I hope I can create something like 5G.

People love to travel. In the 1970s, anyone who was lucky enough to have a bicycle would be the envy（羡慕的对象）of others. Then, green trains came out. But they ran at a speed（速度）of 30km per hour. In the 2010s, the speed of China’s fastest trains had risen to 350km per hour.
For my mom, she had her first train trip when she was 17. But now children at my age can visit many places thanks to the highly developed transportation network. I have visited Beijing, Tibet and Xiamen so far.

Mr. Guo is a teacher in the city of Xi’an. He asked his students to hand in their homework through a QR code. “We spent an hour or two in class learning how to generate the codes, and in the end everything gets easier.” said Guo, “When students finish the homework, they keep it on Wechat. Then, each student makes his own QR code and gives it to me. So I can check their work anywhere using my computer or mobile phone. "
The QR codes can be sent to Mr. Guo by email. QQ and WeChat. When Guo scans his students’ QR codes, their homework appears on his phone. He finds that their homework becomes more creative, with many pictures, music and even videos.
Guo’s students like the new way and think it is interesting. “We are living in the information age. Many students like to work with computers, which makes learning more fun,” said Tingting, a student of Guo’s.
“Paper is not easy to keep, but the code is easy to keep and share.” Guo said, “This new technology is worth trying to use in education. Education itself is a kind of creation. I don’t want my students to fall behind the times.” However, some parents are worried. They are afraid that their children will spend too much time on computers and less time communicating with teachers. But in fact, it’s unnecessary. Students still need to look up information in books and write it down when they do their homework. They only use the codes when they hand in their homework, which doesn’t take them too much time. Also, for teachers, it allows them to check the students’ work at any time. And it’s also an easy way to share homework with other students.
1. How long did it take Mr. Guo to teach his students how to generate the code?2. How can the QR codes be sent to Mr. Guo?
3. What is the advantage of using a OR code to hand in homework compared with paper?
4. What do some parents worry about?
5. Do Guo’s students need to do their homework on WeChat?
6. 书面表达
读了以上短文，你一定对创新有更深的认为，请就这一话题用英语写一篇短文。

Mr. Guo’s story makes me think more about creativity. As we all know, creativity is important to our lives. It brings us many new things and ideas. Without creativity, our lives will never change and become more and more boring.
6 . 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.
Now, 4G takes about 100 to 200 milliseconds (毫秒) to send and receive data (数据). 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 (障碍物), 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 (撞击) because they don’t receive instructions in time. With 5G, this lag will be greatly lowered, 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 refrigerator could automatically (自动地) 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.

7 . There is much heated discussion today about 5G. Your Internet experience is not pleasant when the net speed is too slow — it takes so long to open a web page and the talk show you’re watching stops every few minutes. But soon it could be a thing of the past. On June 3, 2020, the Chinese government announced (宣布) that 5G services would be provided around the country.
5G is the 5th generation network. It is a new network after 1G, 2G, 3G and 4G and it can connect everyone and everything together. 5G speed can be very fast. In the near future, 5G network will cover many cities in China.
5G will make self-driving cars possible. For safety, self-driving cars need super-fast data transmission (传输) to communicate with their nearby environment. 5G is just what makes self-driving cars achieve this. Even airplanes will become “smart” in the near future. Passengers will be able to use 5G networks in the air to connect to the Internet or order food and drinks.
5G will be a big help for students who take online classes. In the world, many people live in poor areas where there are no schools. But with 5G, this will change. Students all over the world will be able to see places like the Great Wall without leaving their rooms.
In addition, 5G will be used in hospitals. It will be easier for doctors to care for patients who live far away by 5G.
However, 5G has its own weaknesses. According to China National Radio, though 5G will make our lives easier, 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 centre and connect the Internet easily. But 5G will only cover about 300 meters. And in order to use 5G, we will have to buy new products specifically designed for 5G that are expensive at present.
1. The underlined word “it” in Paragraph 1 refers to ______.| A．the talk show | B．the slow net speed | C．the web page | D．the heated discussion |
①online classes ②self-driving cars ③“smart” airplanes ④hospitals without doctors

| A．To show 5G is perfect. | B．To give an introduction of 5G. |
| C．To call on people to use 5G. | D．To explain how 5G becomes popular. |
8 . If you look at the top of your phone, you will usually see a little symbol that says 3G or 4G. The “G” stands for the “generation（代）” of your mobile network（网络）. The 5G mobile network is 100 times faster compared with the 4G mobile network.

However, it takes time to send and get this information. With this kind of lag, the car accident might happen because the car doesn’t get instructions in time. With 5G, this lag will be greatly reduced（减少）and make the cars safer.
5G could also be used to make the Internet of Things(IOT) stronger. This refers to a large online network that connects（ 联系）all things and people. For example, with the IOT, your fridge could order eggs online when it finds there are no eggs left inside. How amazing!
