i saw your advertisement for English classes in this month's English Today magazine and I am interested in coming to your school this summer.
I studied English for six year at school and I have to use English frequently in my job. However, I now feel that it is necessary to continue my studied. I would especially like to improve my pronunciation. Please could you send me more information about your courses, and an application form ? I would also like some information about housing.
I look forward to hearing from you soon.
Sincerely,
