Dear Prof。 Herthwell，
Many thanks for your kind hospitality and the honor you showed me during our delegation’s recent visit to your university。
It was nice of you to introduce me to so many of your famous professors and celebrated scholars at your university。 We had a safe and sound trip home。 Now we have resumed our work。
Meanwhile， I hope you will someday pay a short visit to our university and give us some lectures on “Modern Western Economics”。
Please have no hesitation in writing to me if you want me to do something for you in China。
With best wishes。
Dear Mr Li，
I’m very excited to write to express my thanks to you。 I am now a freshman of Wuhan University， which I have been dreaming about。 Mr Li， I still remember the days when you taught me English。 My English has been improved greatly because of your creative work。 However， at one time， the pressure of examinations， too much homework and the high expectations made me depressed。 I was tired of the warning that if I didn’t do my best， I wouldn’t have the chance to go to college。 Thanks for your encouragement; if not， I wouldn’t have realized my dream。 And now I really understand you。 I wish more and more of your students could go to their ideal colleges。 Are you still so busy? How I miss you!
Hoping to hear from you soon。
