問題詳情:
Do you get enough sleep? With so much homework it's often difficult to get the rest you need. But you need to try, because sleep keeps you healthy and it stops you getting fat.
Recently, a group of US scientists did a study (調查) of kids aged between 8 and 13. The study found that if kids sleep for just one extra (額外的) hour each day, the chance of their getting fat is cut by about 30 percent (30%).
Why? When people don't get enough sleep, they become tired. When they are tired, they don't exercise enough. Also, kids like snacks: If they are awake (醒着的) an extra hour or two each day, they have more time to eat snacks or other unhealhy foods.
So, how much sleep should you get? Scientists suggest 10 to 11 hours a night for kids aged 5 to 12. For older kids,eight to nine hours will do.
1. How many reasons are given why people might get fat without enough sleep?
A. 3. B. 2. C. 1 D. None.
2. If you are under 10, how long do the scientists advice you to sleep?
A. 10 to 11 hours. B. 8 to 9 hours.
C. 8 to 13 hours. D. As long as possible.
3. Where was the study done by the scientists?
A. In China. B In Britain. C. In America. D. In Japan.
4. What does" eight to nine hours will do" mean?
