作文
How to Keep Healthy
Everyone wants to be healthy. Firstly, I think a good eating habit is very important. We should eat lots of vegetables and fruit. We shouldn’t eat too much junk food. Drinking milk is also good for health. Secondly, we should have enough sleep. Usually we need at least eight hours’ sleep every night. Thirdly, we need to exercise, such as walking, running and playing ball games. Exercise is good for the mind and the body. Of course there are many other ways to keep healthy. But I think having good habits is the most important.

Here are the results of the student activity survey in class13, grade 8.
Ninety percent of the students watch TV every day. Only ten percent of them watch TV once or twice a week. None of them watch TV three or four times a week at all. As for using the Internet, eighty percent of the students use the Internet every day. The other twenty percent of the students use it three or four times a week. Most students use it for fun and not for homework. The results about playing sports are also interesting. Thirty percent of the students play sports every day. Twenty percent of the students do is once or twice a week. Fifty percent of the students do it three or four times a week.
It’s good to relax by using the Internet or watching TV, but I think playing sports is the best way to relax. It’s good for our health.
