一篇英语作文（关于健康）

我不知道我写的这篇能不能帮到你
Dear Tom,
I am sorry to hear that you are ill at home. You are absent for so many days that make me worried about you. We all know that you have a very poor health. You study hard and have very little exercise. That makes you ill and can't have lessons on time. I think this is also a warning for you. You should have more exercise! Healthy is one of the most important things on human beings! For example, you can go to school and go home on bicycles instead of cars. You can run or rollarskate for some time on weekends. I am worry about you and I hope you can take my advice. I hope you can cure illnesses as soon as possible.
Your friend,
XXXXXXXX
