Dear editor，

    I am a student from a key school. Therefore, I find myself tiring of studying all these days, which worries me a lot of. Though I often got high marks in exams, I don't like it at all. I often think all the subject will become useless while I grow up except English. So I am eager to learn and practice English in my spare time. But I have to spend most of my time solve problems in maths, and chemistry to prepare for the college entrance examination. I also can't afford live up to my parents' high expectations. How do you think I should do with this situation?

Yours，

Li Yue
