如何与国外老师发邮件？
我大概和100多个国家的同学、导师发过email，就我个人而言，总结起来就是“投其所好”四个字——你希望得到哪个国家导师的青睐？英美的？澳洲新加的？还是欧洲大陆的？
首先，你要对目标导师的个人兴趣有所了解（一般导师个人资料里都会有显示），比如是否发表过某某文章，是否担任XX主席等等。然后就可以投其所好了。举个例子，假设你想申请UCSD的生物，对你来说就比较简单了，因为UCSD的生物系可以说是整个SD最“英国化”的，所以如果你想给英国导师留下好印象的话，那么你的邮件就可以这样写
Dear xxx， Thank you very much for your time and consideration in accepting me as a PhD student in the fall. As you can see from my CV， I have a strong background in molecular biology with an emphasis on cell and developmental biology. I am writing to inform you that I will be applying to the Program X of the School Y(学校Y的X项目)， which is also your area of expertise （我是这样引用的你的一篇论文）. I would be very honoured to have the opportunity to work with you and learn about genomics/molecular biology/cellular biology etc from you first-hand！I wish you every success with Program X and look forward to hearing back from you soon！
祝好！
当然可能用不上这么正式，但是大致方向是这样，如果再加上一点你申请的项目的进度就更好了（表明你是一个积极的人）。另外切记一定要写英文邮件！
