填空题
Early to bed, early to rise, makes a man healthy, wealthy (富有的) and wise (聪明的).
This is an old English saying. Have you ever heard it before? It means that we must go to bed early and get up early in the morning. Then we shall be healthy, and we shall also be rich and clever. This is true. The body must have enough sleep to be healthy. Children at young ages should have ten hours' sleep every night. Children who do not have enough sleep can not do their work very well. They will not be clever and they may not become rich.
The body also needs exercise. Walking, running, jumping, swimming and playing games are all exercise. Exercise keeps the body strong. Exercise also helps the blood (血液) to move around inside the body. This is very important. Our blood takes food to all parts of our body. The head also needs blood. Exercise helps us to think better.
