在英语四级考试中，非常容易丢分的作文，也是大家认为最难提升的一项。下面，小编给大家进行详细分析，大家可以作为了解。

一、四级书信格式要求

1、抬头：收件人的姓名

2、正文：三段式

3、落款：祝福(yours sincerely)+写信人名

二、感谢信格式模板:

Dear ______,I am writing to extend my sincere gratitude for __________________(感谢的原因). If it had not been for your assistance in __________________(对方给你的具体帮助), I fear that I would have been___________________(没有对方帮助时的后果). No one would disagree that it was you who___________________________(给出细节). Again, I would like to express my warm thanks to you! Please accept my gratitude. Best wishes. Yours sincerely， Li Ming

(注意：抬头的Dear+人名顶格靠左写，后面一定要加逗号!落款yours sincerely和写信人名顶格靠右写，yours sincerely后面也一定要加逗号!Yours sincerely为书信的惯用套话，这个必须得有!)

三、真题解析

写作要求让自己写一封感谢信来表达你对帮助自己克服困难的朋友的感谢。虽然书信大家可能在复习的时候准备的较少，但其实只要抓住了书信的基本格式，即多了抬头和落款，正文的写作应该较为简单，尤其是第二段，大家可以按照熟悉的原因分析段的方式来写。

1、写作思路：

第一段：表明对朋友的感谢并点题;

第二段：朋友用哪些方式帮我在哪些方面克服了困难

第三段：再次表示对朋友诚挚的感谢并祝愿朋友身体健康。

2、范文：

Dear Tom,

I am writing to extend my sincere gratitude for your great help when I failed that vital English interview. If it had not been for your assistance in giving me those brilliant suggestions and warm encouragement, I fear that I would have lost my way.

No one would disagree that it was you who stayed with me and pulled me through the hard time. First and foremost, you told me it is the priority for me to calm down. This is due to the fact that the ability to stay sober and positive made me come up with quite a few ideas to cope with the consequence that failure triggered. Furthermore, you made me learn to analyze my lack of interview skills and find solutions. Plenty of evidence has shown that this work played an indispensable role in my success the next year. Last but not the least, you helped to build my confidence.

Again, I would like to express my warm thanks to you! Please accept my gratitude. Best wishes.

Yours sincerely,

Li Ming
