每年的申请中，美国出国申请人都会因为各种各样的原因对美国本科申请文书准备不全、不符合标准，甚至写作方式不正确而影响录取。美国本科申请文书由三大组成部分，下面我们介绍一下美国本科申请文书之推荐信吧。
美国大学留学申请文书——推荐信
1、根据所申学校要求选择推荐老师或是同龄人撰写推荐信。一般是三封，具体数量和要求根据学校要求而定。
2、有些学校需要推荐人在网上提交推荐信，需要推荐人提供自己的邮箱地址。申请者可以选择帮助推荐人申请一个邮箱，或者让推荐人将收到的邮件转发给自己处理。
3、推荐信要用推荐人所在单位抬头纸打印，落款处签字，放入推荐人所在单位信封里(若所在单位没有自己信封可用普通的信封代替)，并在信封两边封口处签字。
4、申请过程中，需要推荐人写一封推荐信的同时填写一些英文表格，由于表格杂且多，需要提前和推荐人打招呼，并和推荐人商量是否可以找人代签。
5、推荐信一般与其他资料一并寄出，建议在11月之前完成。
6、有的学校要求推荐信由推荐人处寄出，如果有此条件可这样操作，如果没有，即可把密封的成绩单放入所有材料内一并寄出。
美国本科转学推荐信如何写
在美国本科转学的申请材料中，推荐信是其中一个重要的申请材料。找对推荐人会为转学申请加分。那么，美国本科转学的推荐信找谁写呢?
第1位是大学的任课老师，班主任或院长等，作为大学的升学指导老师来完成大学的推荐表格和推荐信。
第2位是高中的老师，可以是你的班主任，任课老师或校长，作为高中的升学指导老师来完成高中的推荐表格和推荐信。
第3位可以是大学的任课教授或者是实习时的领导，他们可以从专业或者实践的角度来写推荐信，以便全面的展现申请人的多方面能力。比如有的转学生是大专已经毕业了的，那这种情况下最后能够出示一封你毕业后实习单位的推荐信。
美国留学专家提醒，申请美国本科转学，前面这两位推荐人是必需的，而且最好都是任课老师。

Dear Professor:
I understand that XXX is applying for admission to your Postgraduate Master’s Program, and has requested that I write this letter of recommendation for her.
I have known XXX as a resourceful and goal-oriented individual ever since she attended my Instrumental Analysis course(score:84) in her fourth academic semester. She often raised thought-provoking questions during the course lectures. Thus,it is natural that I like discussing with this young girl and enjoy becoming more familiar with her and her aspirations. In her sixth academic semester, she took my course of Electrochemical Analysis(score:89).The more I get to know her, the more I find she is talented at chemistry. With her outstanding talent and solid background in chemistry, she also did quite well in most of her other courses during her undergraduate study. I feel strongly that XXX’s unusual talents and abilities will stand her in good stead for a quality chemistry education, and your university will provide the best opportunities for her.
While at XXX University, XXX had excellent performances in all subjects of her studies and demonstrated great potential, but she is more than a knowledgable bookworm;she is an outstanding leader. She is not only the President of the Student Union in the College of Chemistry, but also the Minister of Commonweal Department of Students’ Association Union of XXX University. She is adept in speech and debate, which give her great capabilities for expression, abstract reasoning， and cooperation. She also took part in and organised many extracurricular activities, such as “Dream Fly” Party of College of Chemistry and Chemical Knowledge Contest of XXX University.
We at XXX University see an optimistic, highly independent， and easy-going character in XXX, with highly unusual determination. She is not to be defeated by any difficulties. She believes that , with hard work, she can achieve anything she wants. I think her confidence in herself is well grounded in her track record.
Judging by what I know of her, I think XXX is fully qualified to pursue a Master’s degree in your program. Therefore，I recommend her with much enthusiasm and I shall greatly appreciate your favorably consideration for her application for admission.
