Dear Mr.Black,
I'm very thank to you for inviting me to stay with you in the coming summer vacation.I have been dreamed of seeing you again so that I can get more help from you in my English learning.And I'm afraid I cannot go to your place in this summer.I've promised my grandmother,that lives in the country,to spend this summer with him.She misses me too much that I find difficult to refuse her request.I'm busy prepare for my examinations at present.I planned to visit you in winter if it's convenient to you.
Best wishes,
Yours truly,
Li Ying.
