Jack, a middle school student, used to work hard at all his lessons. He usually got up earliest and
went to bed latest of the family. He hardly ever did outdoor activities. His parents worried about his
health. They asked him to get relaxed by watching TV or playing sports, but he wouldn't follow them.
Finally, one day he fell ill and had to stay in hospital for several weeks. Now Jack is in poor health.
Though he goes to school every day, he doesn't do so well in his studies as before.
     From Jack's story, we can see that health is very important. If you become sick, you may not go
on with your education, and then you can't make your dreams come true. On the other hand, if you are
strong, you can enjoy yourselves to do everything well.
     Then how should you keep fit? First, you should spend some time exercising every day to keep fit.
Second, you must go to bed and get up early. If you get up early, you can breathe fresh air (呼吸新
鲜空气) and make your heads cleverer. In a word, health is no less important than working hard for
us. So we should, on the one hand, work hard, and on the other hand, pay much attention to our health.
