假设你是李华,你的朋友Jenny向你询问如何保持健康。请你给她发一个邮件提些建议。内容要点如下:

Dear Jenny,
　　 How nice to hear from you! In your letter you asked me how to keep healthy. I would like to give you some advice.
　　 As you know, we teenagers grow very fast, so we need plenty of nutritious foods, such as fish, meat, and beans, especially fresh vegetables and fruits. You’d better not eat too much sweet. Also, you should take physical exercise regularly instead of studying in the classroom all the time. For example, you can play basketball or swim after school. What’s more, having enough sleep is very important. So I advise you to have at least eight hours of sleep every day and not to stay up too late. Only in this way can you keep fit.
Yours,
Li Hua

这是一篇邮件，文章的要点已经基本给出，时态为现在时为主，同学们基本上只要需要翻译成中文即可，要注意选择较高级的词汇如regularly，再使用适当的连词如What’s more 等可以让文章成为一个整体，更为流畅。
