Dear Zhang Wen,
I haven't seen you for days. I hear you have had a bad cold. How do you feel now? You asked for sick leave(请病假) several times this term. I think you should do something to improve health. I have some for you.
First of all, you should eat less fast food and more healthy foodas vegetables and fruits. And I have noticed that you don't drink sowater. That's it's easy for you to catch a cold. Second, you'd make sure that you get at least eight hours' sleep every day and a glass of warm milk before bed is a good choice. Don't stay up too late at. Early to bed and early to rise makes a man healthy, wealthy and wise. Last but not least, you shouldan active part in sports. You can do some exercise between classes and play ball games with us after school.
you follow my advice, you will become stronger and healthier. And I wish you will be better soon.
Yours,
Li Hua
