星期五 晴朗
近些年来，各地高考英语书面表达多采用书信类题材。书信类作文是要求考生以书信形式向别人传递某种信息、表达一种态度或者说明某件事情。
书信类首句写作时重点掌握以下两点：
一、人称定位---第一人称
书信总是以第一人称出现，因而写作时常用这样的词汇或句型
I’m writing to ...
I‘m so glad that you....
Sample 1
Dear Ms Jenkins,
I'm Li Hua from your English writing class last term. I'm writing to ask for your help.
Sample 2
Dear David,
I’m writing to invite you to the lecture on Chinese calligraphy
which is the art of writing Chinese characters and especially
refers to the rules of writing with a brush.
Sample 3
I’m so glad to receive your last letter.I can’t thank you enough for your advice and helpin my English study，
Dear Editor,
As a student reader, I am writing to talk about the English textbooks published by your house.
Sample 4
DearJack，
Thank youfor your letter asking about our discussion on low-carbonlifestyle.
二、使用非谓语中动词不定式表达写信的目的，即某种类别的书信
Sample 1
Here，I‘m writing to thank you ...
to thank you不定式短语表示感谢--感谢信
Sample 2
Dear Frank:
I am writing to apologize that I have lost the valuable book you were so kind to lend me last week.
to apologizethat...一封道歉信：.
Sample 3
I'm writing to apply for the job which you ....
to apply for the job申请一份工作---申请信
一句话，写作书信的首句时必须完成两项任务：
1、我在做什么？
2.我写信的目的是什么？
