题目：
某英语网站进行了一次中学生健康情况调查，发现很多中学生的健康状况令人担忧，主要原因有：饮食结构不合理；体育锻炼不足；心里压力大；不能与人很好的沟通等等。为此，他们发起了题为“How to keep fit”的征文活动，倡导中学生的健康生活方式。请你写一篇80字左右的英语短文，说明如何保持身体健康。（文中不得出现作者本人的真实信息）。 how to keep fit
答案
As we all know, health is very important. But how to keep fit? Firstly, we should have a good diet. That’s eating more fresh fruit and vegetables, but less junk food. Drink more water instead of Coke or other unhealthy drinks. Secondly, it’s good for us to take more exercise, such as running, walking, ball games and so on. At last, we should learn to relax ourselves. We can listen to some light music, chat with families or friends and have a good sleep. To keep fit is not difficult if you care it a lot.
