If you look at the top of your phone, you’ll usually see a little symbol that says 3G or 4G.1. But these symbols will become things of the past after 5G networks fully arrive.
On March 30, 2019, Shanghai vice mayor Wu Qing made the first 5G video call on a Huawei Mate X Smartphone.2.
About 100 times faster than 4G networks, 5G will let people download(下载) and upload data (数据) faster than ever before. But 5G won’t just bring faster mobile internet.3.
For example, 5G will help to make self-driving cars safer. Today’s self-driving test cars have one problem—lag(延迟). When the car “sees” an obstacle(障碍物), it sends this information to a data center and receives instructions.4.With this kind of lag, the cars might hit each other because they don’t receive instructions in time. With 5G, this lag will be greatly lowered, making the cars safer.
5G could also be used to help the internet of things(IoT). IoT is a large online network that connects all things and people. Fast internet speeds will be the key to developing this technology. 5.For example, with IoT, your refrigerator could automatically(自动地) place an order online for eggs when it finds that there are no eggs left inside.
A.Shanghai has also become the first city in China to start testing 5G networks.
B.5G will help us buy eggs quickly.
C.People can use it for many other things as well.
D.However, it takes time to send and receive this information.
E.The “G” is the “generation(代)” of your mobile network.
F.The IoT could be used in a lot of ways.
G.5G networks are much faster than 4G or 3G.
Has anyone ever told you that eating carrots will help you see in the dark?This is just one of many incorrect beliefs you may have heard. Below, TEENS has picked out scientific explanations for three mistakes that people make about their eyes. Let’s take a look.
Can eating carrots improve your eyesight?
Carrots are rich in vitamin A, which helps the eyes to turn light into information for your brain. This allows people to see in darker places.However, eating more carrots won’t help you see better. A certain minimum amount will help, but a large number of carrots will not give you superhuman vision.
If your parents have bad eyesight, will you have bad eyesight, too?
Myopia(近视)can be passed from parents to children. A study by the American Optometric Association found that if both parents are myopic, there’s a 33 to 60 percent chance that their child will be. For children who have one parent with myopia, the chance is 23 to 40 percent, and it’s down to 6 to 15 percent for kids with non-myopic parents. So if your eyesight is bad, your children might still have good vision.
Do color blind people see the world in black and white?
Color blindness doesn’t usually mean that people see the world like an old movie. They usually can’t tell certain colors apart, especially green and red. Another commonly confused pair of colors is yellow and blue.Our eyes have cone cells(视锥细胞)that sense different wavelengths (波长)of light. If these cells don’t work properly, color blindness occurs.
There are different levels of color blindness. Some people are only color blind in low light.
However, in the most serious form of color blindness, everything is shades of gray.
1.Which can help the eyes to turn light into information for the brain?
A.vitamin A B.vitamin B C.vitamin C D.vitamin D
2.According to the article, eating carrots_____.
A.stops the brain from seeing
B.doesn’t help you see better at all
C.will give you superhuman vision.
D.is good for your eyes to some degree
3.If both parents have myopia, their child’s chance of having good eyesight is_____.
A.40-67% B.33-60% C.23-40% D.6-15%
4.What is the cause of color blindness, according to the text?
A.Watching movies for too long.
B.Getting too little exercise.
C.Cone cells not working properly.
D.Changes in the wavelength of light.
5.What is the purpose of the article?

When you travel in China, you can often see some very special puppets (木偶) in many gift shops. They are thin, colorful, made of animal skin (皮) and in all kinds of shapes. They are traditional Chinese shadow puppets.
The Chinese shadow puppet play (皮影戏) is an old art. It's also called "the business of the five", because a shadow puppet play group is usually made up of five people. One moves the puppets, one sings and the other three play instruments.
How did this art start? There is a story behind it. It is said that more than 2 000 years ago, the wife of Emperor Wu of Han died from illness. The emperor was very sad. His minister (大臣), Li Shaoweng, one day saw children playing with dolls and the shadows of the dolls were dancing on the wall. Then Li went back home and made a puppet of emperor's wife. He put sticks (技条) on the puppet's hands and feet to make it easy to move.
When night came, he put up a curtain (帘), lit a candle, and invited the emperor to sit before the curtain. Li moved the puppet from behind the curtain. The emperor felt like he was seeing his wife again and was very happy. After that the shadow puppet play became the emperor's favorite pastime.
