有好几个人问了，我想干脆贴出来吧，这是导师写的，愿意做我回来以后的推荐人的其实很简单：
It is my pleasure to have Ms. LIU Shanshan as my graduate student and research assistant in our department from 2000 till now. As her advisor, I was impressed by her diligence and talent in her study and research work. She is the only one to graduate one year in advance in her class this year.
As a returnee from USA, I know the education there could do what a great help for working in China. I encouraged her to pursue her PHD degree in the United States with the highest enthusiasm. I believe she deserves such opportunity to learn more advanced knowledge there.
And I have talked about her future plan with her. I will be her reference after she gets her PHD degree and comes back to realize her plan. I really hope she could join our department, but I know her ambition is not only to do the research, but also to emerge her research result into industry application in China. Upon her request, I will recommend her to the R&D center founded by leading company, such as Delta, GE, HUAWEI and UTRC. I personally have good relationship with these companies and have cooperated with their R&D center. I am sure Shanshan will surely get her position there, along with her excellent academic performance and overall ability.
I would like to provide more information upon your request.
