     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 U. S. scientists

did a study (研究) of kids aged between 8 and 13. The study found that if kids sleep for just one extra

(额外的) hour each day, the chance of their getting fat is cut by about 30 percent.

     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 unhealthy 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.
