Dear Mr. Black,
I’m very thank to you for inviting me to stay with you in the e 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, she lives in the country, to spend this summer with her. She misses me too much
that I find difficult to refuse her request. I’m busy with preparing for my examinations at
present. I planned to visit you in winter if it’s convenient to you.
Best wishes,
Yours truly,
Li Ying
