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(近視)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.

At the Fire Science Academy, students learn how fire behaves, how to use firefighting tools, how to save people, and of course, how to put out a fire.

The academy recently received a fire truck that will help students become familiar with the trucks used by real firefighters, according to Mark Davis, a teacher at the academy.

“It’s an important part of the program,” Davis said. “It allows our students to understand the everyday tools used in the fire service. It also gives them a sense of pride to enter into public service.” The fire truck will also help students practice before taking the state firefighter test, Davis said.

Schmidt said she was interested in the opportunities the academy presented.“It was my decision to go into this program,” she said. “My dad has been in this service for almost 25 years and I wanted to follow in his footsteps and learn and understand what he goes through in his day-to-day life.”

“The academy is strict and students have to be comfortable with standing to attention for most of the day,” Davis said. “I like the discipline(紀律) aspect because I feel like a lot of high school students sometimes go the wrong way, and with this, it’s not possible,” Schmidt said.

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(下載) and upload data (數(shù)據(jù)) 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(延遲). When the car “sees” an obstacle(障礙物), 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(自動地) 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.
