Dear Mr Zhao,
    I'm a student from Class 2 Grade 6. I want to join the English club. I like English very much, but I'm not good at it, so I want to join the club to improve my English. I think it's a good place for me both to practise my English and to make friends.
    If it's possible, please call me at 3366823. Thanks.
    Yours sincerely,
    Zhang Lei
