英语作文书信给同学（汇集20篇）

In my primary school life, I met a lot of small partners, but there was a little buddy. How could I not forget it? His impression in my mind is too deep to be deep.

I remember when I started school soon, I and he was a good friend, then we often play a lot of trouble, but now we have become very good. He was very tall, medium (i.e. standard oh), lips looks funny, eyes always sparkle, do not know who thought he was in the discharge of it, ha ha.

He is a mysterious man, but he is always able to do something very delicate, so that my good friend has to admire it. Sometimes at night, he always call me, because he knows that my mom and dad went to the field, he must be very lonely, so he called me up, I appreciate him very much. I remember one time when my hand was hurt. He was very concerned about me. He always asked me right and left to ask. I saw he looked at me with concern and I didnt cry.

Well, to speak of my friend, he is an example of my heart.

Dear Sue,

I’m Li Hua, one of your students in China. It’s almost a month since you left us. We all miss you and are very grateful for what you did for us.

We are busy as usual. We had an English speech contest the other day. I won the first prize! This again reminds me of all your kind help. Do you still remember the trees we planted together on the hill behind the school? Yesterday, we went there and watered them. The tree you planted yourself is growing well, and the whole class decided to name it Sue Wood. Will you come back to see Sue Wood?

How is everything with you lately? We hope to know more about you and your American students. Hope to keep in close touch.

All the best.

Yours，

Li Hua

Best wishes to you！

yours，

Dear Sue,

How are you doing?

I am writing this letter to say "thank you." First and foremost, it is

clear that you, just like "our foreign mother", were very patient to us.

Additionally, needless to say, you taught me a lot, not only English knowledge

but also your life wisdom;consequently, all of us have fallen in love with

English and study. Last but certainly not least, there is no doubt that we had a

great time together, which we will keep in mind forever.

By the way, I cant wait to tell you something new about my class. After

you left for the America, we had an English competition. We all did very well,

using the knowledge you told us. No one can deny you helped us so much!

Sue, can you give me some information about your life in America? I miss

you so much. I am looking forward to your early reply!

Best wishes!

Yours truly,

Li Hua

Dear Mary,

Thanks for your last letter. Im so glad that you have been able (at last! ) to arrange a holiday in Australia. As I fear I wont be able to meet you at the airport when you arrive, nor will I be able to be home until later in the afternoon, so here are some instructions and suggestions. There is a bus from the airport to the city. It is much cheaper than a cab. Take the bus to the city and ask to get off at Town Hall railway station. To get to my place in the eastern suburbs you have three options. You can either take a cab, a bus or the train. I suggest you take the train, since the airport bus will leave you right at the station. Get off at Cliff Station. From there you can either walk to my place (about ten minutes) or take a taxi. Probably you should take a taxi as you will have luggage.

When you arrive at my flat, ring the intercom for Flat 2. My friend Lillian will be at home and she will open the front door for you and let you into my flat. Presumably you will be tired and want to sleep. But if you feel like some exercise after that long flight, you could stroll down to Cooper Park, which is only ten minutes away ? you can see it from the window. Cheers and looking forward to seeing you.

Yours sincerely,

Annie

P.S. I will leave something for breakfast in the fridge. Help yourself to anything you want.

给Tom的一封信

Dear Tom，

Your letter reached me yesterday.Im so sorry.And these are my some

thoughts.

Advantage of the cellphone is we can in touch with eath other

convinentely,however,there are some disadvantages about it.For example,if you go

to school with the cellphone ,it would make bad influence on teaching.Whats

more,the cellphone is harmful to your health,your eyes will be worse and

worse,your body will be weaker and weaker and so on.So,I dont think its

terrible for you to use the cellphone at the school.

These are my thoughts,I hope they will be useful for you.

Li Yangis my classmate. She is a good student and always ready to help others.

One day on she way to school, she saw a little girl crossing the road. A car was coming towards her quickly and the girl was too frightened to move. The car nearly hit her. Just then Li Yang rushed up to her and caught her by the arm. The little girl was saved. She told him where she lived, and he took her home. When Li Yang hurried into the classroom, the teacher had already begun his lesson. She told the teacher why he was late.

今天的英语课上，来了一位新同学，他奇奇怪怪地来，又糊糊涂涂地走了。

就在上课前，那位同学提着书袋进了教室，Borling老师问了一句：“你是学习几级的？”他满脸惊讶地说：“我是学初级的。”同学们立马嚷道：“我们学二级。”那位同学带着奇怪的眼神跑出了教室。

我们准备了一下，要上课了，那个同学又回来了。我真佩服他，他最配得上灰太狼那句经典台词：“我会回来的。”不过，这次在他的身后还跟着两个大人，一个是剑桥英语的老师，另一个好像是他的妈妈。经过她们两个大人的一番唠叨，我终于明白了，原来他已经上四年级了，以他这个年龄，他妈妈想让他插班进二级班，Borling知道情况后安排他坐下了。

课马上开始上了，突然Borling想起了什么，问新同学：“你有没有英语名字？”“没有。”那你就叫……叫‘Tom’吧。”就这样，Tom来到了我们班。

课间，Borling把Tom叫来接受学前测试。二级书上，他连“this”都读不出来，Lacy笑了笑。Borling就说他是害羞。考了几个，Tom都不会，Borling把一级书拿来让他读，他又连读“red”都犹豫半天。最后被Borling送到一级班去了。他离去时的眼神，还是带有一些疑惑。

到现在，我都不知道Tom的真实英语水平。

亲爱的陈紫函同学

你好！我叫韩书莲。嘿嘿！我们俩见面应该不止一次了吧！不知道你记得我吗？我很想和你做好朋友，你愿意吗？

你是不是很奇怪我给你写信啊！告诉你吧！其实就是为了今天这个事儿。陈紫函啊！你微笑的时候总是能迷住我，可是今天你怎么会哭起来了啊！我知道今天有人故意撞了你一下，而且还是个男生，我也亲眼瞩目这事情发生的过程，我知道你心里其实一点儿也不好受，但是你没在我们面前表现出来。谁也没料到你竟然一个人跑到操场哭了起来了！幸好我发现了，就才把彭青青、张诗艳叫来劝你！你作为新同学的身份来到我们班，第一天就让你过得不开心，这以后你可怎么办啊！放心吧！还有我在呢！你以后有什么伤心的事啊！你也可以给我说，我会帮你分担，给你安慰，这样你也许会好些。假如以后还有男同学欺负你，你不要哭，不要动不动就流眼泪，你可以给老师说，让老师来教训这群家伙！假如老师不在，你也可以忍着，但那个男同学做的太过分了，你可以还手，解心头之恨。反正不要哭鼻子！我最看不惯女生哭了，你哭了，我不开心，你也不开心。对吧！所以呢？你就不要哭，这样大家都开开心心的嘛！这些事情只要你不去理会，不去在意就可以了！

新的学年也刚刚开始，我也希望你微笑面对每一天，开开心心过好每一天，你也不要害羞和我们说话，女同学之间嘛！大方一点没关系的！

祝你

学习一步登天

烦恼扬长而去

你的同班同学：韩书莲

小峻同学

你好！

祝贺你，你在一年前，终于用优异的高考成绩实现了你的理想——跨入了重庆医科大学的校门。

曾记得，你在01年曾获得重庆市“中华杯”征文一等奖的《张开理想的风帆》中想象道：“一个春天的早晨，我按照惯例，来到重庆市中心人民医院上班，……就听到杨院长好！杨院长好！”为此想象，你的这个愿望已实现了初端——考入了重医大。你将来一定会成为一名“神医”，你当年的梦想将逐步成为现实。

再继续努力吧，你的这一远大抱负会进一步实现的。你的小学老师，将继续等候你的佳音。只要继续努力，边学习，边工作，继续深造，争取把研究生或更高的文凭拿到手。目前，在校夯实坚实的医学理论基础知识，待毕业后，再多集累一些医务实践经验，不断反思，不断研究。

小峻同学，我真羡慕你。我从小就想当一名医生。因为医生可以减轻或消除病人痛苦，让病人早日走上康复之路。可惜，这个机遇我不曾相逢。我曾在77年我国招生制度恢复的第一年，报考的是万县中医学校，可生不逢时。由于当时我国差教师，因为我在考前当了一段时间的民师。当时国家要振兴教育事业，凡是考前教过书或代过课的考生，必须读师范专业，因此我与当医生的机会擦肩而过。

本来，我从小就自学过一些中医及针灸的医书。如：“诸药识性。此类最寒，犀角解乎心热，羚羊清乎肺肝……”针灸歌诀：“三里内关穴，胸腹中妙诀……”哎，可惜无缘当医生。然而，你却实现了你当年的梦想，我真羡慕你呀！因为，你有了一个从医的机会，真是太好了！

小峻同学，你的父亲，是我们奉节的一位好医生。他医德高尚，医术精湛。希望你将来超过他的业务水平。待将来，边工作，边撰写一写医学专业书籍。待袁老师从网上看到你成长的好消息！待若干年后，成为一名医学专家。

你的母亲——贺同志，是一位从小关爱你成长的好长辈。据街坊传诵，在她工作业余，不知多少次，在厨房窗口等待你回家午餐；不知多少次，拿着雨伞在人民路小学门口焦急地等待你的身影出现。你的母亲既是一位好民警，又是你第一位优秀的启蒙老师。她真是你的一位善良慈母呀！因此，你更要以优异的学业成绩报答她。将来并以优异的学业成绩、精湛的医疗技术、高尚的医德医风孝敬你的二老。这也是一个曾经教过你几年的小学老师的期盼。

小峻同学，你确实找到了一门高尚的职业，我真羡慕你。因为医生越老技术越高超，医术越精湛。

想当初，我的父亲1958年曾在我县一家大型国营煤矿职工医院当医生。当年曾与县内57名医生报考过重庆医科大学【当时为半工半读学制】。他幸运地同县内2人考上了重庆医科大学，但是由于该国营煤矿当时极度缺少医生，被时任厂党委胡名贵书记挽留在岗从医（后来胡升为县劳动局长）。就这样失去了读重医大的机会。

当今，你考入了重医大，真幸运呀！我97年教过的周威、瑾秋同学都在三军医大读过书，周威已在解放军324医院就业，99届小学毕业生（我班学习委员曹旭）在西安四军医大毕业后已在云南一医院从医。

你的机遇真好，以后年龄越增长，医术越高明。试想，其他的职业有这样的优势吗？一般职工退了休，无事可做，但医生退休后，可继续为人民救死扶伤，多自豪呀！我的父亲的老师是一名医生，他曾亲口对我说过一句话：“官不可做医可学。”但我认为，为民办事的好官还是可做的，但医更可以学。学好医，终身受益。你的选择是对的。

4月14日的《夔门报》上刊登了我班学生刘牛写的《二十年后的我》，他在文中想象了他二十年后当医生的情形。此文也供你参考。

21世纪，属于信息时代。建议你在休闲时，可通过在网上搜索母校“奉节县辽宁小学”、“钱直树校长”、“袁祚萱”等词语或其他相关词组关心一下母校，可以通过输入你其他学姐、学兄、学弟、学妹收集信息。如：肖旺、袁老师教过的唐祎（《黄金时代》）、刘显成（西华师范大学）、黄中祥（渝中区市政园林局）、陈奎（巫溪县统战部长等）、你的同桌柯可（留学美国）、李印鹰等……可以看一下母校近四千师生朝气蓬勃的精气神，及每一位校领导认真导、每一位老师认真教，每一位同学勤奋学的新风彩。校园活动精彩纷呈，新大门、新操场、教室干净整洁，花坛四周，花团锦簇，鸟语花香。母校——奉节县辽宁小学真是日新月异面貌新呀！

最后，我用（2005年版）《当代重庆优秀作文精萃》p201中，你在上面发表的作文《张开理想的风帆》一文的简评，作为本次交流的结束语吧

“理想的风帆激励我们去奋斗，实现理想需要我们脚踏实地去努力。”

杨峻同学，你已经努力了，希望你再接再厉，继续腾飞吧！

顺祝

学业有成，将来医术精湛！

你的小学老师：袁xx

10月6日夜

假若你是《21th century》报纸的编辑，有一学生向你写了如下的一封信，请你根据来

信的内容写一封回信，帮他出出主意。字数约为100左右。

Dear Editor,

My physics teacher is very strict with us. I often feel nervous in his classes because we are punished by being made to stand for a few minutes if we cant answer his questions. Its embarrassing (尴尬) to be made to stand in class, so I hate physics classes. However, I really want to do well in physics. What should I do?

Yours sincerely

Zhang Ying

Dear Zhang Ying,

I am sorry you are having difficulty with your physics classes. Teachers have many different ways of encouraging students to put in more effort — it seems as though your physics teacher thinks fear is the best way! He does it because he thinks it will produce results. If you feel that it is stopping you from doing your best then you should tell him. You say you want to do well in physics and if your teacher knows this, he will be pleased. It is only when students are not trying as hard as they can that a teacher is forced to take action. If he is aware of your worries, perhaps he will suggest other ways of helping you improve your work.

Editor

张颖

亲爱的张颖，

我很抱歉你在物理课上遇到了困难。老师们有许多不同的方式鼓励学生投入更多的精力，这似乎是你的物理老师认为恐惧是最好的方式！他这样做是因为他认为这会产生结果。如果你觉得这是阻止你做你最好的，那么你应该告诉他。你说你想在物理方面做得很好，如果你的老师知道这一点，他会很高兴的。只有当学生没有尽可能地努力，他们可以教师被迫采取行动。如果他知道你的担心，也许他会建议其他的方法来帮助你改善工作。

[我的新同学们英语作文

英语书信是英语中最常见的应用文体裁，用途极为广泛。以下是小编整理的大学英语书信作文格式，欢迎阅读参考！

1、信头(heading)

信头是指发信人的姓名(单位名称)、地址和日期，一般写在信纸的右上角。一般公函或商业信函的信纸上都印有单位或公司的名称、地址、电话号码等，因此就只需在信头下面的右边写上写信日期就可以了。

英文地址的写法与中文完全不同，地址的名称按从小到大的顺序：第一行写门牌号码和街名;第二行写县、市、省、州、邮编、国名;然后再写日期。标点符号一般在每一行的末尾都不用，但在每一行的之间，该用的还要用，例如在写日期的时候。

其中日期的写法，如1997年7月30日，英文为：july 30，1997(最为普遍);july 30th，1997;30th july，1997等。1997不可写成97。

2、信内地址(inside address)

其中在一般的社交信中，信内收信人的地址通常省略，但是在公务信函中不能。将收信人的姓名、地址等写在信头日期下方的左角上，要求与对信头的要求一样，不必再写日期。例如：

3、称呼(salutation)

是写信人对收信人的称呼用语。位置在信内地址下方一、二行的地方，从该行的顶格写起，在称呼后面一般用逗号(英国式)，也可以用冒号(美国式)。

(1)写给亲人、亲戚和关系密切的朋友时，用dear或my dear再加上表示亲属关系的称呼或直称其名(这里指名字，不是姓氏)。例如：my dear father，dear tom等。

(2)写给公务上的信函用dear madam，dear sir或gentleman(gentlemen)。注意：dear纯属公务上往来的客气形式。gentlemen总是以复数形式出现，前不加dear，是dear sir的复数形式。

(3)写给收信人的信，也可用头衔、职位、职称、学位等再加姓氏或姓氏和名字。例如：dear prof. tim scales, dear dr.john smith。

4、正文(body of the letter)

位置在下面称呼语隔一行，是信的核心部分。因此要求正文层次分明、简单易懂。和中文信不同的是，正文中一般不用hello!(你好!)

正文有缩进式和齐头式两种。每段书信第一行的第一个字母稍微向右缩进些，通常以五个字母为宜，每段第二行从左面顶格写起，这就是缩进式。

但美国人写信各段落往往不用缩进式，用齐头式，即每一行都从左面顶格写起。商务信件大都采用齐头式的写法。

5、结束语(complimentary close)

在正文下面的一、二行处，从信纸的中间偏右处开始，第一个词开头要大写，句末用逗号。不同的对象，结束语的写法也不同。

(1)写给家人、亲戚，用your loving grandfather，lovingly yours，lovingly等;

(2)写给熟人、朋友，用yours cordially，yours affectionately等;

(3)写业务信函用truely yours(yours truely)，faithfully yours(yours faithfully)等;

(4)对上级、长辈用yours obediently(obediently yours)，yours respectfully(respectfully yours)等。

6、签名(signature)

低于结束语一至二行，从信纸中间偏右的地方开始，在结束语的正下方，在签完名字的下面还要有用打字机打出的名字，以便识别。职务、职称可打在名字的下面。当然，写给亲朋好友的信，就不必再打了。

7、附言(postscript)

如果一封信写完了，突然又想起遗漏的事情，这时用p.s.表示，再写上遗漏的话即可，要长话短说。通常在信末签名下面几行的左方，应于正文齐头。

注意：在正式的信函中，应避免使用附言。

8、附件(enclosure)

如果信件里面有附件，可在信纸的左下角，注上encl：或enc：，例如：encl：2 photos(内附两张照片)。如果福建附件不止一项，应写成encl：或encs。

我们有时可看到在称呼与正文之间有re：或subject：(事由)字样。一般在信纸的中间，也可与“称呼”对齐。还应在底下加横线，以引起读信人的注意，使收信人便于在读信之前就可了解信中的主要内容。事由一般在公务信函中使用，也可以省略。
