再问： 高一英语100字
再答： Dear friend,
My name is Zhang Lin. I am fifteen years old. I am in the City of Guigang. I am a boy student in Ming Yang Middle School. I like collecting stamps, playing football and computer games. I often sing English songs with my classmates. I enjoy traveling with my parents or friends. I don,t like dancing. I think staying at home all day is terrible. I,m not interested in playing the piano at all.
To improve my English, I want to find a pen-friend in America. If you want to be a friend of mine, please send an e-mail to me soon.
Yours
Zhang Lin
