> 实例一：如何向教授要邀请信？
Professor [Name]/ Dear Dr. [Name],
(I hope this email finds you well.)
邮件开头的常用客套话，也可省略
My name is […]. I took your [Course name] course last semester.
简要介绍自己及与教授的联系
You may remember me [e.g.coming to your office hours after every test to go over some of my wrong answers/ discuss essay prompts / etc.]
如果和教授在课下有过一定接触，可以写进来；
You may not remember me [e.g. because I tend to put my nose to the grindstone and study on my own.]
如果和教授从没有课下的接触,可以简要地为自己开脱；
[Course name] was a very challenging subject for me and I was proud of the [Grade, e.g. A-] I received in your class.
写出自己本课的成绩（一般会选择成绩较好的课的任课老师写推荐信）
I am currently in the process of applying to [University/College/School name] and I am trying to gather a few letters of recommendation.
另起一段，写明来意：准备申请某学校，因此需要邀请信。
Because I enjoyed [ e.g. your class and teaching style so much/ your research/ etc. ], I decided to start by asking you. Would you be able to write me a strong letter of recommendation for my [University/College/School name] application?
如果和教授有过一定接触，可以这么写；
Because of the way I study it has been difficult for me to develop a relationship with my professors . I enjoyed your classroom and teaching style [ your research, etc. ] , so I decided to ask you first. Can We meet to discuss the possibility of you writing me a strong recommendation[medical school] application?
如果和教授从没有接触，可以先提出面谈邀请信的事宜，让对方先了解你；且用语更加委婉）
I would be more than happy to meet with you at your convenience. Of course I would also provide my personal statement, CV, and any other material that you would like.
另起一段，陈述把自己现有的资料（除了PS、CV外，还可以提供自己做过的research/project/paper的资料）提供给导师，保证对方有内容可写而不是仅凭上课对你的记忆。*有时也有自己先写好推荐信、让教授过目修改的操作（需和教授讨论）
If you don’t feel comfortable writing me a strong letter of recommendation, please don’t feel obligated to say yes. I completely understand.
另起一段，如果和导师有过接触（但还是不太熟），可以参考如上表述；don’t destroy the professor’s negative face给对方留出选择余地。
I realize that writing a letter of recommendation would be a burden on your time and it means a lot to me that you would take the time to read and consider my request.
但如果你是课堂上的隐形人，和导师完全没接触，就要把自己的要求写的更加的委婉，给对方留出选择余地的同时表达出迫切和感激。
Sincerely,
[Your Full Name]
结尾附上自己的全名（可以加上自己的联系电话、Student Number等有关信息）
实例二：如何和教授套磁？
Dear Professor XXX,
(I hope this email finds you well/ I hope this email finds you in good health)
同邮件开头的常用客套话，也可省略
My name is XXX and I am writing to you as a prospective student in your Bioengineering Ph.D. program at Stanford, commencing in the Fall of 2012. I attended your presentation in Langer Lab Seminar this November and I am particularly interested in your research that is directed towards designing novel approaches in decoupling biochemical and mechanical properties of cell scafoulds using the microribbon-like hydrogels, and mixed co-culture enhanced cartilage matrix production.
套磁第一步：
1)简要阐明自己的身份
2)套磁的动机(a prospective student in your Bioengineering Ph.D. program at Stanford)
3)自己与教授认识的契机(attended your presentation in Langer Lab Seminar this November and I am particularly interested in your research that…）
Currently, I am a graduate Materials Science student at the University of XXXX and currently carrying out my master research at the University of XXX, focusing on novel formulations for ultrasound-mediated drug delivery mechanisms in gastrointestinal tract. As a side project of interest, I also brainstormed and designed a research plan of developing a biomimetic scaffold for interstitial cells in GI smooth muscle to study its electrical-signal properties for the purposes of treating obesity and GI disorder. I would like to pursue doctoral researches in an area that combines both engineering and biology, and am fascinated by the research that is being conducted in your group.
套磁第二步：建立“连系”
1)简要阐述自己的研究领域、背景
2)之后的研究方向是如何与目标教授相关的
During my undergraduate experience in Oxford and summer internships, I have acquired a wide range of laboratory techniques including scanning electron microscopy, confocal microscopy, rheology, electrospinning and tissue dissection. I seek your guidance on opportunities for research in your group as a new PhD student in the Fall of 2016, and your opinion on how my research interests align with those of your lab. I am attaching my CV and would be grateful for the opportunity to speak with you in the future.
套磁第三步：
1)大概阐述自己的技能
2)以及这些技能如何辅佐自己胜任职位
3)附上CV！！！说再多的话教授就不会看了，顶多扫一眼你的CV，感兴趣了就会联系你， 静候佳音即可。
Thank you for your time and consideration.
Best regards,
XXX
