英语作文：how to keep healthy

 There're many ways to keep healthy. First of all, we should keep taking exercises every day. We can walk to school instead of taking a bus. After school, we can spend an hour playing ball games.  If we live in a high-rise,  we can walk upstairs or downstairs. Second, we should have a balanced diet. Finally, we must remember: "Early to bed, early to rise is the way to keep healthy, wealthy and wise."
