Dear Sir or Madam,

I saw your advertisement for English classes in this month's English Today magazine and I'm interested in coming to your school in the summer.

I have studied English for three years but I have never been to the United States and I feel that this is now necessary, especially 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 accommodation.

I look forward to hearing from you as soon as possible

Sincerely,

John
