Dear Sir，
Thank you for you offer of invite me to the summer English course in your school.As for your choice between the two courses,I prefer the four-week course for 60 hours of study.Because of this would allow me more times to do some travelling and make a few new friends either.Of all the subjects I’m learning at school,I like English best.I had been learning English for 6 years but my spoken English remains poorly.So I hope to take this chance to improve it.If is possible,I’d like to stay with a family for a couple of days in order I can know some customs in England.I believe I will have wonderful time this summer.
Yours truly,
Li Hua
