Suppose you were recommended by Professor Sun to get further education in Yale University last June and now you have been admitted by that university. Write a letter to Professor Sun to express your gratitude in about 100 words. Do not sign your own name, using “Li Ming” instead.Dear Professor Sun,
I am writing to extend my gratitude to you—without your help I would not have been a postgraduate student of Applied Mechanics Department of Yale University.
Last June, you helped me with no reservation when I applied for Yale University. You wrote a recommendation letter for me to Professor W, the dean of the department. You gave me instructions on how to fill the application forms and write the application letters. Whats more, you also taught me how to take care of myself and get along with others, which I believe are lifes great lessons.
Your help enabled me to fulfill my dream to pursue my studies in a great university. In the following days I will remember what you have told me and work and study hard to be a capable, conscientious and responsible person.
Yours truly,
Li Ming
感谢信
语言注意点感谢信应充分表达自己的谢意，切不可给对方草率的印象。可借助谈对方的帮助来进一步表达感激之情。言辞应真挚、得体。
Suppose you were taken good care of by Aunt Sun when you pursued your studies in Los Angels where Sun lived. Write a letter in about 100 words to extend your appreciation. Do not sign your own name, using “Li Ming” instead.Dear Aunt Sun,
It is a great pleasure to extend my sincere gratitude to you for your hospitality and consideration while I pursue my bachelors degree at University of California.
As soon as I arrived in Los Angeles, you found me an apartment near my university. When I met with difficulties you often sent your daughter to help me and when I felt homesick you often talked to me patiently. You told me how to improve my efficiency in both work and study and how to get on well with teachers and schoolmates. Furthermore, you invited me to dinner on nearly every weekend.
Without your help, I would not have graduated with honors and found a satisfactory job back here in China. I know I can never repay you for everything you have done for me in the past four years, but you can be sure that Ill never forget it.
Best regards.
Yours faithfully,
Li Ming
