1 . Do you know 5G? It is the fifth generation (代) of mobile network technology.
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 (数据). But 5G can 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 second s using 5G.
5G+ transport
5G will also bring us safer self-driving cars. These cars can send signals (信号) to each other. They also talk to traffic lights and road sensors (传感器). 5G will allow cars to react (反应) even faster than human drivers.
5G+ smart homes
5G also makes the Internet of things possible. Internet of things is a large network that connects everything to the Internet. Smart homes are part of it.
Choose the best choice from A, B or C according to what you read.

2 . More and more people are using mobile phones now. Smart phones are used as televisions, cameras, and music players. They are also used for sending e-mails or surfing the Internet. If someone talks about mobile phones, many Chinese will think of Huawei.
In China, even in the world, Huawei is a wonder (奇迹). Ren Zhengfei built up (创建) Huawei company in 1987. The company sold 58.4 million smart phones in the first season of 2019. Huawei has got the second place at the mobile market.
Now, Huawei has been the leader in 5G field. It has more than 75,000 top engineers and scientists on research. They try their best to bring digital (数码) and high technology to every person and place. It’s more convenient for modern people to live in a rapid way. What a useful technology 5G is!
We are looking forward to seeing a stronger Huawei. It provides a faster and better communication way for us. It also brings “Created in China” to the world.
判断句子正(T)误(F)
1. You can use Huawei mobile phones to take photos.2. Ren Zhengfei set up Huawei company in 1987.
3. Huawei has got the first place at the mobile market.
4. Few top engineers and scientists work on research in Huawei company.

3 . On the morning of May 30th, 2019, Huawei helped the BBC use 5G to report news. It was the first time that 5G was used in the world! Actually, China just began to use 5G in June 2019. What’s the most special about 5G? 5G lets us send and receive information in a very short time. Now, 4G takes about 100 to 200 milliseconds(毫秒) to send and receive information. But 5G will help the time down to 1 millisecond or less. The big change that 5G brings will not only make our mobile network faster, but also deeply change our lives in many ways.
First, 5G can connect with amusements. 5G is about 100 times faster than 4G. This means you can download a movie in seconds by using 5G. Also, VR games will become more popular with 5G. 5G will make people feel the games even more real.
Second, 5G can connect with traffic. 5G will also make self-driving cars safer. These cars can send messages to each other. They also “talk” to traffic lights and road sensors(传感器). 5G will allow self-driving cars to have faster reaction(反应) than human drivers.
Third, 5G can connect with smart homes. 5G also makes the IOT possible. IOT is a large network that connects everything to the Internet. Smart homes are part of it. Smart homes can make the machines automatic. For example, if the sensor feels the floor becoming dirty, a smart floor cleaning robot will sweep the floor by itself. And your bread maker could start making breakfast ahead of time or before you get up.
Although not everyone can use 5G networks now, China is trying its best to let everyone use 5G as soon as possible!

4 . Do you know who Shen Yifei is? No? You need to know about this young man. He is one of China’s youngest and greatest 5G scientists. He is only in his twenties. He is really a gifted man.
Shen Yifei was born in Handan, Hebei Province in 1997. He seemed to be born with the ability to learn. At the age of five, he started school. He used only 10 years to finish primary school, junior and senior high school. After he became a 15-year-old university student in Chien-Shiung Wu College, Southeast University, he realized, “No matter how strong you are, there is always someone stronger. All you know is just the tip of the iceberg.” So he was more hard-working than before. He passed all the exams with flying colors.
Since he finished university, he has got three great patents in science and technology. These patents are really important for the development of 5G. What he is doing in 5G will make a big difference to the world.
“If the young people are strong, the country will be strong.” With Liang Qichao’s famous saying in mind, Shen Yifei keeps working hard in science study. We believe this young man will have a bright future and hopefully our country have more and more excellent scientists like him.
