一个人的力量是微弱渺小的，因此在我们不断成长的工作生活中，或多或少总会得到别人的帮助，使得自己在一时困顿之下突破迷雾渡过难关，实现学业或者事业进步。
受过帮助后，礼貌的你一定会说声“Hey, thanks for the assist!”。一声感谢虽然温馨，但毕竟太轻，留不下痕迹。如果你能够静下来用心写一封感谢信（Letter of Appreciation），既可以充分表达自己的衷心，又足以让帮助你的人暖心，还可以激励他们坚持助人为乐的善心。更有甚者，说不定哪一天你的感谢信还将有可能帮对方一回（文末有案例）。
一、感谢信写作解析
一封优质的感谢信不需要太长，也不要过分宣泄自己的感激之情，简单诚挚就好。
1. 问候
在多数情况下，“Hi [Name]”就够了。不过在稍微正式的语境下，比如写给你的领导、人事经理或者你的教授，用“Dear [Name]”会更合适。但如果是在非常正式的语境下，则应使用“Dear Ms/Mr. [Last Name],”。
2. 正文
首先说明收件人具体帮了你什么。虽然偶尔使用笼统的感谢也可以，但具体说明帮助的内容会显得更实诚。比较一下以下两种说法：
- 笼统感谢：Thanks for always being willing to lend a hand when I need you
- 具体感谢：Thanks for putting in extra time to make our presentation a success.
然后列举一下帮助的相关细节，包括对方做了哪些你觉得特别有用的事，或者说哪方面的帮助是远超过普通人的。不要小看细节，这些细节的娓娓道来，将使收件人充分感受到你是多么重视他（她）的付出。
3. 结尾
一般在信的末尾写上“Thanks again”，并附上你的签名就够了。
小贴士
如果你想快速将感谢信发给对方的话，使用电子邮件是个不错的选择。但如果是对于一些重要场合的帮助，比如律师事务所的面试，寄送一封亲笔手写的感谢信则会更佳。考虑一下你收到帮助的场景并做出合适的选择。
二、感谢信案例精选
下面为大家提供一些感谢信的参考案例，但请注意感谢信切忌照搬照抄，而是信的内容要充分与你的实际情况和内心感受相关，否则一封虚情假意的感谢信只会带来适得其反的效果。
1. 感谢工作表现优异
Hi Mark,
Thank you for escorting our guest speakers during the workshop last week. You went out of your way to make everyone feel comfortable, which allowed me to focus on setting up the AV equipment and running sound checks.
I spotted you not only getting people their presentation materials but also fetching water and coffee. If anyone needed anything, you were there to provide it for them. All of our speakers mentioned how helpful you were. Your thoughtfulness and attention to detail helped forge lasting relationships. We couldn’t have done it without you!
Thanks again,
Jill
2. 感谢领导（正式口吻）
Dear Ms. Latham,
I’d like to express my deepest appreciation for your excellent mentoring during my internship at Latham & Sons. You not only celebrated my wins, you turned every mistake into a learning opportunity. Your guidance has been influential, and I know it will shape my developing skills and habits as I move into my professional career.
Warmest regards,
Mitchel
3. 感谢员工
Hi Imani,
I want to tell you how much I appreciate your help getting our store ready for opening day. You worked hard, and you were always willing to put in extra time if the situation called for it. I’m grateful for your attention to detail—our displays look amazing as a result of your skills.
I’m confident you’ll be a great asset to the business and an excellent resource for customers now that we’ve opened our doors to the world. Keep up the good work!
Thanks again,
Daniel
4. 感谢支持
Dear Jordan,
Thank you for your support during my family crisis. I’m deeply grateful not only for you covering my workload while I was away but also for the times you checked in on me. Knowing you had my back allowed me to focus on my family’s needs, which is a kindness I’ll never forget. I appreciate everything you’ve done more than you’ll ever know.
Thanks again,
Hailey
无论你是领导还是员工，请将感谢信归档存好。对于领导来说，这有助于你评价员工的表现。对于员工而言，你永远不会知道什么时候这些感谢信会在某个关键时刻突然就派上了用场。
多年前我在一个经济崩盘失业率高企的非洲国家工作，需要招聘一名打理住所的佣人。面试了几个年轻人后，来了一个举止得体的黑人大爷，他报出的薪水要求竟是年轻人的两倍多。在我们准备拒绝他的时候，多看了一眼他材料里几封昔日白人雇主留下的手写感谢信，文字上用情真切，内容是赞赏有加，最后因此我们录用了他，并且他的表现也没有让我们失望。
最后，再啰嗦一句，感谢信归感谢信，更重要的还要看今后的实际作为。这句话是约翰·肯尼迪总统说的：
As we express our gratitude, we must never forget that the highest appreciation is not to utter words, but to live by them.
当我们表达感谢时，我们绝不能忘记感恩的最高形式不是说出的话，而是实际的作为。
