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 four-week 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 better. I had been learning English for eleven years but my spoken English remains poorly. So I really hope to take this chance to 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, what I’m particularly interested in. I believe I will have wonderful time this summer.
Yours truly,
Grace
