Dear Mr. Smith
Thank you most sincerely for your kind letter inviting me to go and stay several days with you in Nanjing. But I am terribly sorry to say that I can't go in this coming summer vacation, for I've promised to go and spend the holidays with my grandmother, who lives in the countryside and is missing me so much.
I'd like to tell you that I am getting on well with my study. And I must owe the success in my English study to your help. At present I'm busy all day long preparing for the examinations and I feel sure I can get high marks.
I do hope we can meet each other again in the near future.
With best regards to you and Tom.
Sincerely yours,
Wang Li.
