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．
