Dear Jack，
I'm sorry to hear that you have a headache， sore eyes and a sore back. And you don't sleep well at night. You play video games too much. That's probably why you are not feeling well. I think you should take breaks away from the computer. You shouldn't use the computer for a long time. You should do eye exercises to relax your eyes every day. You shouldn't sit in the same way for too long without moving. And you should get lots of exercise.
I hope you get well soon.
Yours，
Li Hua

Dear Lisa，
I went to an old people's home with some volunteers. We did many things for the old people. We brought them some flowers and fresh fruit. And we helped clean their rooms. After that， some of us sang songs and danced for them. Some of us read newspapers to them. Others talked with them. How happy they were！
I think this activity is very meaningful. I learned that we should care for the old around us.
Yours，
Wang Wei

Dear Sir or Madam，
I think we teenagers should help our parents with housework.
First， doing housework helps us to develop independence. We can't depend on our parents all the time. We should learn how to take care of ourselves now.
Second， doing housework is a kind of exercise. It helps us stay healthy and strong.
Third， since we live with our parents， it's fair for us to help to make the house clean and comfortable.
All in all， doing housework helps us to learn life skills. So it's important for us to do some housework.
Yours，
Zhang Yun
