Dear my friend， Tommy：
Thank you for your last letter.here are photos of me and my sister twin Coco. As you can see ， in some ways we look the same，in some ways we look different. We both have black hair and black eyes.Alough my hairs is shorter than hers.She is more outgoing，I am quieter.I think I am smarter than her.WE both like sports， alough she is more athletic than me.I think I am smarter than her.My favorite sbujects are phycics and chmistry 。 Her favorit subject is P.E. However， we both like going to the parties.
Is it surprising that I write the letter for you ? Not one time had I wanted to express my heartfelt gratitude for you face to face . But I’m so shy that I can’t do that .Thus , I decide to say thank you in this way .
Meeting you is the most fortunate thing in the world . Your emergence brightens my life deeply . You know ,I used to be such a shy ,a quiet girl . I was afraid of contacting with others so that I merely had pretty few friends . All days I stayed at home , and my life was dull . It was not until you volunteered to assist me that my life set out changing . You took me to wander the streets to observe the world which greatly broadened my eyes . You encouraged me to take part in kinds of activities that promoted my courage and confidence . You were always enthusiastic to introducing me to your friends when I was fear of expressing myself in public . The wonderful characters you own deserve me to learning .Your optimism and vigour impress me so much .
Now , I have become confident and outgoing . I can firmly confront the difficulties ,never shrink . My dear friend ,thanks for leading me to a new world , thanks for letting me feel shiny warmth and never making me lonely . Comparing to what you have dong for me , simple thanks seem to be minor , but it’s my sincere appreciation and gratefulness .
Blessing you happy forever .
在考研英语的Part A 小作文部分，书信作为考查的重点所在，种类繁多。在前面我们曾就以题目为例，详细地解析过建议信、投诉信和咨询信的写作方法及其注意事项。今天本文就对考研英语小作文中的第四类书信——感谢信——进行深入的分析。
感谢信，英文中称为 letter of thanks或letter of gratitude。顾名思义，就是写信人因得到某人或某单位的帮助、支持或关心而向对方表示感谢的信件。书写时语言要真诚感人，表达感激时要恰到好处，切忌过于夸张、让人心生虚伪之感。
Suppose your 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.
You should write neatly on ANSWER SHEET 2.
Do not sign your own name at the end of the letter. Use “Li Ming” instead.
Do not write the address.
首段：I would like to convey in this letter my hearty gratitude to you for your recommendation for me. Without your help, I wouldn't have been a postgraduate of Applied Mechanics Department of Yale University.
第一句话直接表明写信目的，即向对方表示衷心的感谢，之后再简要陈述事由，即为了什么事情向对方表示感谢。此句之后，为了让自己的感谢之情表现得更为真诚和强烈，第二句需进行进一步的强调，可用Without your help, I wouldn't have done??。
中段：Last June, when I applied for Yale University, you wrote a recommendation letter for me to Professor Washington, the dean of the department. What’s more, you also taught me how to take care of myself and get along with others, which for me are of great significance.
