email的格写英语作文的注意事项：
写邮件的格式：
1、信头：指发信人的地址和日期。写在信纸的右上角，可以从靠近信纸的中央写起。信头上面要留空白。先写发信人地址。地址的写法与汉语不同，要先写小地方，后写大地方。在地址的下面写上日期。日期的顺序是：月、日、年，或者：日、月、年。例如：may 17 XX。在年份之前有一个逗号。
2、称呼：指对收信人的称呼。写在信头之下，从信纸的左边开始。写信给熟悉的人，一般用dear…或my dear…作称呼。如：dear li lei，dear miss thomas或my dear dad。
3、信的正文：指信的主体部分。从称呼的下一行第一段顶边写。从第二段起每段第一个词都缩进3或5个字母写。
4、结束语：指正文下面的结尾客套话。一般从信纸的中央靠右写起，第一个字母大写，末尾用一逗号。在非正式的社交信中，常用yours或sincerely。假如对方是亲密的朋友，可用sincerely yoursyours等。
5、签名：指发信人签名。写在结束语的下面，稍偏右。
写邮件的格式英语作文：
Dear professor Li.
I am a undergraduate from the Department of physics and I fortunately took a major course on which you lectured. Your lessons impressed me deeply.
As a senior, I face the choice between hunting for a job and continuing to study. I prefer to apply for a chance to pursue a Master’s degree abroad.
I have taken required English exams and got excellent scores. What’s more, I have finished my personal statement, which is attached to this letter. I’m now writing to ask if you can write a reference for me, which will greatly facilitate my admission into a U.S. university.
Best wishes for your health.
Your Student.
