首先写抬头 XX proof
然后写 It is hereby to certify that there's no accident happen to XX's（填要证明的人的名字） car during the drive in China.
英语证明信常采用书信格式，但多略去收信人的姓名、地址和结束语。称呼用语多用"T h it many cncern" ，意为“执事先生”有关人士” “负责人” ，但此项也可省去，直接开始正文。正文起首句多用This is t certify that？结构。
比如： American Embassy To whom it may concerned, We hereby confirmed that Mr。（你的名字）is a staff of our company。
He has worked in our company for more than (5) years till present and will continue his obligation after he come back at YYY/ZZZ。 （你回国的年月日） Any question regarding his working history please do not hesitate to contact us at fax number____, tel number______。
Best regards， （你经理的名字） （你公司的名字） ————此处盖章。 2006/01/14。
称呼用语多用“To whom it many concern”，意为“执事先生”“有关人士”“负责人”，但此项也可省去，直接开始正文。
正文起首句多用This is to certify that„结构。 证明内容简洁明了，实事求是，不必多用客套语。 正文右下方注明证明人头衔及姓名或证明机构名称。
进行相应的格式调整 恰当使用目的语套语 用词准确恰当

I'm confident that I can succeed.Now i will introduce myself brieflyI am 26 years old,born in shandong province .I was graduated from qingdao university. my major is electronic.and i got my bachelor degree after my graduation in the year of 2003.I spend most of my time on study,i have passed CET4/6 . and i have acquired basic knowledge of my major during my school time.In July 2003, I begin work for a small private company as a technical support engineer in QingDao city.Because I'm capable of more responsibilities, so I decided to change my job.And in August 2004,I left QingDao to BeiJing and worked for a foreign enterprise as a automation software test engineer.Because I want to change my working environment, I'd like to find a job which is more challenging. Morover Motorola is a global company, so I feel I can gain the most from working in this kind of company ennvironment. That is the reason why I come here to compete for this position.I think I'm a good team player and I'm a person of great honesty to others. Also I am able to work under great pressure.That's all. Thank you for giving me the chance。
Hello Mike, long time no see. How are things with you?
Let me say something about me first. I'm pretty good recently. I dumped my ex-girl friend and made a new one, who is much younger than the ex. We just come back from our exicited holiday. Can you see my tanning face that is a witness of our wonderful time. I also had a promotion in my job. Of course, my pay is up accordingly. I do enjoy all of these.
I hope you are well too, Mike.
1.比较对照 比较对照有两种，一是逐点比较，二是整块比较，即AB交错或先A后B:1）逐点比较：多数人认为这种AB交错的方式可以避免行文的单调沉闷，对比的效果更鲜明突出。如：There are basic differences between largeand small enterprises. In a small enterprise, you operated mainly throughpersonal contacts. In a large enterprise, you have established “policies” ,“channels” of organization, and fairly strict procedure. In the smallenterprise you have immediate effectiveness in a very small area. You can seethe effect of your work and of your decisions ground. In the large organizationyou are normally taught one thing thoroughly. In the small one the danger is ofbecoming a Jack-of-all-trades-but-master-of-none. In the large it is ofbecoming the man who knows more and more about less and less.2） 整块比较 It is easy to be a winner. A winner canshow his joy publicly. He can laugh and sing and dance and celebrate hisvictory. People love to be with winners. Winners are never lonely. Unlikewinners, losers are the lonely ones of the world. It is difficult to facedefeat with dignity. Losers can not show their disappointment publicly. Theycan not cry or grieve about their defeat. They may suffer privately, but theymust be composed in public. They have nothing to celebrate and no one to sharetheir sadness.2.分类 分类是人类认识客观世界的重要手段之一，也是描写事物、解释观点最有效的方式之一。
如：1) As far as political views are concerned, people fall into threecategories. First are the conservative people. Conservatives are opposed tosudden or great changes. Second are the liberal people.These people are infavor of progress and reform. But their opinions often seem to idealistic. Thethird type is the moderate people. The moderates keep everything withinreasonable limits. They are more practical in this hard world. In my opinion,most people seem to belong to this group.本段采用平行排列的方式，按人的政治观点分为三类：保守、自由和温和。2) These are several reasons why I decidedtom attend Bingston University . First of all, the tuition is reasonable.Secondly, the university has a deferred payment plan., which lessons the loadof peasant families like mine. Another reason is that Bingston has the finestteachers in its graduate program. My chief reason, however, is Bingston'sprogram in agriculture, my chosen field, which is recognized as the leader inthis area.该段采用主次排列的方式，分析了作者决定上Bingston大学的原因。
3) According to Mr. Li, the fifteenstudents of his cLASS fall into three groups. Seven of them work hard and studywell. They always get good marks in examinations and are often praised by theteachers. Li calls them “good students”. The monitor, the secretary of theYouth League, and the captain of the cLASS volleyball team, are quick infinding out what their fellow students are interested in or what they should doas a collective. They always organize proper activities at the proper time. SoLi calls them “good organizers”. Four other students are very kind to theircLASSmates, always ready to lend them a helping hand. They help to clean thecLASSroom and the corridor even when they are not on duty. Li says that theyare “ good comrades”. “What about yourself?” someone asks him. “I'm a group bymy self ——a good observer”.该段不同于以上两段，不是先分类再解释，而是先说明其特点，然后定义分类。虽分类并不科学，却达到了其幽默之目的。
例证型段落的写作方式多为先提出主题再列举事例。在事例之前一般有For example或For instance。
例证后面，根据情况还可以加上结论句。如：In order to prevent non-smokers from beingaffected, measures must be taken to reduce the chances of smoking. A lot ofwork can be done concerning this. For example, in 。
看你是什么情况了， 如果已经毕业，就用 ：
It is to verify that Student ### used to studied in our school from 2005 to 2007.
Hereby to certificate!
It is to verify that Student ### has been studying in our school from 2005 to 2007.
