Dear Editor I am writing to you to 1 you about my problems with my family. I am very 2 now and I need your help. I don’t think my parents 3 me. They don’t care what I like doing, but always talk about how 4 study. They don’t let me 5 out with my friends at weekends. They always ask me 6 home and study. I’m sure I could still study very well even if I had more time to play, but they just 7 me. We often argue(争论) with 8 . I really hope that my parents can 9 my friends. What shall I do ? How can I get them to understand me? Please give me 10 . Thank you ! Yours Michael
