• 作文范文（要求：全文背诵）

How to keep healthy

( How to keep in good health )

Tom is a middle school student. He is an 11-year-old boy. He has some good habits. He also has a few bad habits. He watches TV for at least two hours every day. He often stays up late. Also, he eats junk food four times a week.

I think, first of all, he should spend less time watching TV. Then he will have more time to read. Second, he should go to bed early and get up early. It is bad for our health to stay up late. Third, he can’t eat too much junk food. He should eat more vegetables and fruit. And it’s healthy to drink a lot of water every day.

To keep healthy, we should do more exercise.
