【正确答案】[范文] March 15, 2011
Dear Tracy,
How have you been? Haven't seen you for nearly two years after graduation. I heard that you would come to Nanjing for a business trip. How about coming to see me and letting me accompany you to visit Xuanwu Lake and Dr. Sun Yat-sen's Mausoleum?
Hope to hear from you soon!
Yours,
Sharon

Dear Sharon,
Thank you very much for your kind invitation! It will be a great pleasure for me to meet you. I still keep in mind those good days of being with you at university. So I'll come to Nanjing at early April. I'll call you when I arrive.
Hope to see you soon!
Yours,
Tracy
