Dear Sir／Madam,

　　I'm writing to ask for some more detailed information on your school. I have a great interest in it and want to learn about it.

　　First, I would like to know what qualifications the teachers there have. Second, how many students are there in a class and what form does the teaching usually take? Third, how can students choose the right course and what's the timetable like? Besides, I wonder how many teaching buildings there are and how they are equipped. And where do the students in your school sleep?

　　I'm waiting for your early reply and I would appreciate it if your reply includes any other useful information.

Yours sincerely,

Li Hua
