Dear Ms Li

I'；m very glad to write to you. I have lot of homework to do at school. I don'；t have enough time to sleep. I nearly have no time to do sports. My friend and I can hardly find time to talk， or play together. When I get back home from school， I'；m not allowed to watch TV， surf the Internet or listen to my favorite music. I feel worried about them. I don'；t know what I should do. Could you please give me some suggestions

Best wishes

Zhang Meng
