【正确答案】 Dear Zhichao,
Congratulations on your being admitted to the Graduate College of Cornell University! Are you going to further studies in the same field as you've been taking up in the undergraduate years?
It has been nearly four years since we met last time at the graduation ceremony. Will you be back during this summer vacation? You know, Facebook could never compare with a face-to-face chat. I still have a vivid recollection of the days when we studied and lived in the same dorm and you were always the best joke-teller.
Looking forward to hearing from you as soon as possible. Congratulations and best wishes for an even more prosperous future!
Yours truly,
Li Ming
