Dear Brad ,

I am a boy in the first grades of a senior high school . I feel uneasily recently . At home I feel like prisoner . I am not allowed to watch TV or surf the Internet . The only thing I have to do it is studying . Every time I got a low mark , my parents will scold me sharply . There's a generation gap among my parents and me , but it's always difficult to communicate . Life are supposed to be colorful and wonderful , isn't it ? How should I devote all my time and energy to the study so as to entering a good university ? I am very unhappy and lost . I need your help .

Best wishes ,

Li Ping
