E

    Artificial intelligence(人工智能), or AI in short, is the science of giving computers and machines ability to think and work like humans. AI scientists and engineers have made a lot of cool technologies.

    AI is rapidly catching up with the human ability to read faces. As a result, facial recognition(识别)is used a lot in the world. Chinese police use this technology to identify criminals(罪犯).Once they caught a criminal when he attended a concert. It also checks the ID of ride-hailing(网约车)drivers and lets people pay for things with a smile.

    AI is also used in self-driving cars, which are believed to be the future of driving. Most drivers may wave or nod at passers-by to let them cross the street, but self-driving cars don't have this ability. Carmakers are testing a light signal system to help them "speak" to humans. The system can show what self-driving cars will do. For example, if a driverless car is yielding(让路), it will flash two white lights side to side. A rapidly flashing light tells passers-by that the car is about to speed up.

    Service Robots also show you know powerful AI is. Imagine this—you come back home from school and your robot housekeeper is waiting for you at the door. After dinner, he teaches you to play the piano, just like a real music teacher. Such thoughts will soon happen in the real world. In the future, more and more service robots will become good home helpers.

    AI is so powerful that it can help human beings and even replace us in many jobs.

David Strayer never texts or talks on a phone when he is driving. Strayer is a famous psychologist (心理学家) at the University of Utah. His research shows that, when driving using a phone can be as dangerous as drinking wine.

Strayer and other scientists warn against multitasking (多任务处理). When we do many things at the same time, Strayer says our brain becomes tired easily. So we may make mistakes and lose attention.When we spend hours on digital devices like videos and computers, our productivity reduces. Too much multitasking reduces our ability to think clearly and creatively. This can result in stress (压力).

What is the best way to help us lower too much stress? David Strayer says the answer is simple: Spend some time in nature.

Strayer and other scientists are studying nature's effect on our brains and bodies. When we are in natural environment, the brain's control center relaxes. Studies show that when people can see trees and grass, they do better on different tasks.

Other psychologists are also studying "nature therapy (疗法) ". In a study at Chiba University in Japan, a researcher named Yoshifumi Miyazaki found that forest walkers did better than the city walkers. He has an explanation for these results. "Our bodies relax in the natural environment," he says. "Humans evolved (进化) in that environment, not in places with tall buildings and lots of traffic. This allows our brains to rest and recover from the stresses of city life. Imagine a therapy that could improve your cognitive (认知的) ability at zero cost. Why not try it at once?

China's Tiangong space station can help scientists study space. It is also a place for astronauts to live and work. How much do you know about the lives of astronauts working in the space station?

For astronauts in space, exercise is important. The environment is very different in space. Doing sports helps astronauts stay healthy. How do they exercise? There are good exercise machines in the space station. They make it easy for astronauts to keep healthy. 

There is no gravity, so astronauts can't take showers like us. Is there a bathroom in the space station? How do they keep themselves clean? Tiangong has a special bathroom. Astronaut s can clean themselves with a wet towel (毛巾). 

What do astronauts eat in the space station? There is bread and milk for breakfast. There are also tasty Chinese dishes, like Kung Pao Chicken, fried rice and fried noodles. There is a special "fridge" to store (储存) food. The food stays cool in it. 

What if astronauts miss their families? There is special communication equipment (交流设备) in the space station. Astronauts can have private (私人的)"sky- to- earth" calls with their families. The astronauts often wear a headset (耳机). It not only helps them talk with each other, but also makes it possible for them to talk to the ground from any place.
