Dear Mr.Smith,
hello,I'm a student of our school.I'm delighted to hear that our English teacher will start to teach three courses named "Spoken English"、"English Writing" and "America Today".I am really interested in the English writing.So I want to join in it.
My English ability is quite well.But I don't feel proud for it,because I want to improve my English more.
I am weak in English Writing,so i'm eager to improve it.This is why i am interested in this class.I hope that I can study English with the students who want to improve English as I,we can help each other.
Thus,I want to become a student of the English Writing class. I believe I can finish my desire.
I'll appreciate it if you give me admission to the class.
