考研英语小作文中主要考察的是应用文系列，其中包括了求职信、祝贺信、道歉信、询问信、推荐信、感谢信等二十多种应用文。在此，新东方在线整理2015考研英语小作文中感谢信写作的万能模板。
感谢信属于个人信函，是用来对馈赠礼物或曾经得到某人的关怀、照顾表示感谢，在西方国家用得比较普遍。感谢信在格式上没有很严格的要求，主要是要写得真挚，表达诚挚的感激之情，不能给人一种草率的印象。
由于感谢的对象、原因和内容不同，感谢信的内容也会有所区别。例如，对朋友赠送礼物表示感谢的信，一定要提到所赠的礼物以及自己对礼物的喜爱之情;又如因为曾在对方家里小住而写的感谢信，一定要提到在对方家里居住时候的感受。但是，无论如何，一封感谢信通常都包括感谢的原因、内容以及诚挚的感激知情。具体如下：
一、信函写作：称呼、正文、落款
1、审题—-判断是个人书信&事务公函
决定：
语域使用：正式：使用礼貌表达，不用缩略语(对公)
半正式：可以使用缩略和口语表达(对私)
非正式：(一般不考)——It depends
呼语： 特定的写信对象：Dear XX
不明确收信人：Dear Sir/Madam, or To Whom It May Concern
2、正文
三段(8句)：写作目的段、细化段、感谢或者期待。
3、各种信函内容安排
A.基本结构
Dear…,

感谢缘由及内心感受,希望回报;

Yours sincerely,
Li Ming
B.我们通过范文来实例说明吧：
Dear Jim,
I am writing to express my heartfelt gratitude. I am referring to that unfortunate accident the other day, when I was knocked off my bike by a taxi.
If it had not been for your timely assistance in giving me first aid, I fear that the Consequences might have been much more serious. Everyone agrees that it was your quick-witted response in that emergency that has led to this satisfactory outcome.
Although nowadays people in mounting numbers talk about the need to be unselfish, we see very few people practice what they preach. If there were more people like you, this world would be a much nicer place.
Yours sincerely,
Li Ming
