【题目】阅读与表达(问答式)

Today, young people spend about six hours a day in front of a TV or a computer and less than four minutes playing outdoors. It is not healthy for the mind and the body when time spent using technology replaces outdoor time.

Some health experts(专家) call green time "vitamin G". Kids who don't get outdoors much are likely to have trouble in school. Doctors believe that is because being outdoors excites the mind more than sitting around indoors. Even those who usually spend a lot of time outdoors notice a difference when they don't get green time. Madelyne P., 14, says, "I feel more tired when I don't get outdoors."

Researchers believe the positive(积极的) effects of green time come from the physical activity in pastimes such as hiking or boating. Exercise produces brain chemicals that improve learning, mood, and sleep. It also improves learning by increasing connections between nerve cells that are important in learning and memory. Some schools hold classes outside for those reasons. Student Hannah Smith, 18, says she believes the outdoors helps her focus and gets her to learn. Learning in a forest sparked her interest in art and photography, too.

Even doctors are helping give their patients a dose of vitamin G.Miller writes "park prescriptions(处方)" for her patients because,she says, "being outdoors is good for health." She finds that when she gives patients park prescriptions, they are likely to continue with them.

Getting outdoors can be simple, just like calling together your family for a picnic lunch. All it takes is five minutes or more of green time. Get outside, and get your vitamin G!

【题目】 There is a famous English saying “You are what you eat”, and it means what you put in your mouth will become part of you. Many experts (专家) use it to tell people it’s important to have a good eating habit. For example, too much sweet food makes a person overweight. To avoid being fat, kids are told to keep off sweet food. However, a team of American scientists have discovered something new about eating sweet food.

“When we say some people are ‘sweet’, we mean they are kind and friendly to us. Perhaps this word can help us learn more about people’s feelings and acts.” said Brian Meier, a scientist from the study team. “Taste is something we experience every day. What we have done is to find whether we can know someone’s character and behavior depending on their taste.”

In one of their experiments, college students were asked questions about their character — whether, for example, they were soft-hearted or not. Then they were asked to make a list of their favorite food. According to their answers, the scientists found that the students who liked sweet food were nicer.

In their another experiment, the scientists found that people who preferred sweet food such as cookies and chocolate were more willing to help other people in need, and those who ate non-sweet food such as chips weren’t. For example, people with a sweet tooth were more likely to volunteer to clean up their city, visit sick children in the hospital and so on.

The result of the experiments is that people’s helpfulness or being nice has something to do with their taste for sweet food. So eating sweet food is a useful way to make people nice and helpful. Next time, try some ice-cream.
