怎么感谢朋友感谢信（精选3篇）
Dear David,
I would like to take this opportunity to express my heartfelt gratitude to you for your very active participation in our recent conference in Montreal on the “future of aviation”. The chairman and board members have also asked me to pass on their sincere appreciation for your efforts in supporting the institute in this important undertaking.
Your skill in chairing the controversial panel on “the role of developing countries in the future of aviation management” was highly appreciated by those representing all sides of that extremely sensitive topic. As well, we have received numerous post-conference requests for the paper you delivered on “the critical issue of cooperation between airlines and airports”. It appears that you my have penned a best-seller with that one!
On both a professional and a personal level, I really appreciated the time that the two of us were able to spend together for fun and reflection during conference down times. I certainly learned a lot about the unique aspects of aviation operation in your part of the world (not to mention the things you taught me about the backhand on the squash court!)
We are currently hard at work producing the “compendium of conference proceedings” document, and we expect to be sending it out to all participants early in the new year.
Again, thanks so much for your enthusiastic participation in our conference. I have no doubt that it would not have been the success that it was without your presence.
Please keep in touch ,and drop in and visit us whenever you are in this part of the world.
Very sincerely
Peter Smithfield

亲爱的李卓识：
你现在在干什么?近几天你经历过什么有趣的事吗?
啊!作为你的好伙伴，好搭档，我想对你说的话简直太多太多了，借这次给你写信的机会，我就一吐为快吧。
我很喜欢看你笑，因为在我认识你之前，你的脸上总是挂着一副严肃沉思的表情，看起来好像很“难”见到你笑似的。和你交了朋友后，不但由于你的影响我的成绩提高了很多，你也经常笑了。
说实话，能和你交朋友，我真的很荣幸。想到以前，我还是一个中游的学生，交了不少坏朋友，还常说脏话(太夸张了点)，觉得跟你学习这么好的同学根本沾不上边，只能看着眼馋罢了。没想到偶然的一次机会，咱们两个竟然交了朋友，并且两人之间的友谊越来越深厚了。自从交了你这位高尚之友，我的学习成绩不但提高了，坏习惯们也都改了，还被老师评为“优等生”。要是没有你的指点与帮助，哪里来的我现在的成就(当然，也有其他人的帮助与指点，不过我还是觉得你对我的帮助是最深刻的)!从你身上我学到了好多，认识到了好多。看来，你和那些曾经帮助过我的人都是我成功的“加油站”呀!
话回到现在的校园生活，看来这时我们已经成为最亲密的伙伴了，上课我们积极地回答问题，比赛谁把老师的问题理解的更彻底，更具体;下课我们总是几个人凑在一堆儿，做一下课后总结或者玩游戏，生活过得紧张而快乐，忙碌而充实，我甚至已经觉得学习是一种放松，一种享受。
呵呵，老说你了。除了你，我还要感谢赵文悦、彭桢哲，他们在学习上也给了我莫大的帮助。赵文悦也是我最亲密的朋友之一，他总是热情地帮助我，帮我解决不会的难题，我一有什么心事总是最先向他说。彭桢哲虽然很顽皮，但他的内心却是渊博的，他平常都读很多书，积累了很多知识和好词好句，等到学哪方面知识的时候正好能派上用场，也给了我们很多启示。
啊!天色不早了，我也该停笔了，再见，李卓识，希望我们的友谊会永远地延续下去……

李崚玮:
你好!
早就想给你写信了。我们已经认识快两年了，你可是我最好的朋友。
两年里，可发生了不少事。有几件事我仍然记忆犹新。
记得有一次，我生日那天你来给我过生日，送给我一条十字架形状的项链。你说你也有一条，和这一条是一样的，还说这是友谊链。我知道友谊链象征的意义，只要两个人戴上它，就会做一辈子的朋友。至今那条项链我保存的完好无损，这条项链是你第一次送给我的礼物，我可不希望这是最后一次。
每次我无聊的时候，就把比较珍贵的东西拿出来，看一看。让我的目光停留的时间最长的，就是这条项链。每次我看到这条项链，我都会想起我们的欢笑，我们的点点滴滴。
在班里，我最佩服的人就是你啦。因为不管你的事情多得数不过来，自己忙得不可开交，你还是能沉下心来，有条有理的把事情做完。每次你管班的时候，总是威风凛凛，让人没有选择的余地，只能按照你说的做。我在这给你提一个意见，你别等还没弄清楚事情的真相，就乱指证谁对谁错。这也是你一个比较大的缺点，这个缺点很有可能成为你人生路上的一块绊脚石。
你因为要带鼓号队练习，所以很晚才能回家，所以让我给你记作业。每次我都把作业记到一张纸上，所以你准备了几个小本子，让我记到本子上。你永远都那么细心，替别人想得那么周全，却把自己忘得一干二净。有些事，如果没有你的帮忙，我恐怕要等到花儿都谢了还没想出个是非来。我真为有你这样一个朋友感到庆幸。
你还不知道吧，前两天你带鼓号队练习时，我在楼上偷笑你呢，因为你的动作很搞笑。不过，看见你指挥完后的手又红又肿，就可以看出你在练习时多么投入，多么认真。
眼看就要毕业了，我们就要分开了，也许我们再也不能像以前那样一块儿笑，一块儿闹了。我真希望时间能过得慢一点，让我们做好朋友的时间长点儿。
希望我们是永远的朋友。
祝：
身体健康，学习进步，心想事成。
