Ｗｅ Ｍｕｓｔ Ｋｅｅｐ Ｕｓ Ｈｅａｌｔｈｙ

As we all know， it is important to keep us healthy. We should go to bed early and get up early. In the morning there is fresh air， and we can do running and morning exercises in the gardens. We should not watch TV too late. It’s very important to keep water and air clean. We should plant more trees and flowers and fight against pollution（污染）.
