One possible version:

　　Dear John,

　　Thank you so much for your email. I’m very happy to answer your questions.

　　In China, we start our summer vacation at the beginning of July. It lasts about two months. We can do many things to relax ourselves in summer vacation. I often go swimming, surf the Internet and watch TV. I will go to a summer school for a month to study English because it is important and I like it. But what I want to do most is traveling with my parents. We have been to many places. This summer, we are going to Beijing. We always have a good time.（90词）

　　I wish to visit you in Canada one day.

　　Yours,

　　Su Hua
