Dear Sir，

Thank you for invite me to the summer English course in your school.As for your choice between the two courses, I prefer the four­week course because of this will allow me more time to do some traveling but make a few new friends.Of all the subject I’m learning at school, I like English best.I had been learning English for eleven years but my spoken English remains poorly.So I really hope to take this chance improve it.If possible, I’d like to stay with a family for a couple of days in order that I can know some customs in England, that I’m particularly interested in.I believe I will have wonderful time this summer.
