大家都知道美国留学至少要写三篇推荐信，那么怎么写，从哪里下手，想必许多同学还不是很清楚。接下来和出国留学网小编一起来看看2019美国留学推荐信书写指南。
第一：我们来看看它的书写内容。
1、申请者的学业成绩或特质，是否具有领导才能，是否具有很强的分析能力等。在这一点上要注意适度，不能因为谦虚对优点加以掩盖，也不能夸夸其谈过高的估计申请者。
2、挖掘申请者自身的特殊之处，例如有很强的沟通能力，或者是擅长某种语言等。
3、就你所了解的范围而言，该申请者有什么比较重要的成绩或是成就，学业上的或是其他方面的。
4、该申请者是否有何弱项，例如之前有过某些方面的挫折，但是从这个失败的经历中获得了什么经验教训等。
5、对申请者未来潜力的描述，即解释推荐人愿意对该申请者做出推荐的原因，以及一旦该申请者获得到该校继续深造的机会会有什么发展等。
第二：接着来看看它的书写技巧。
1、宜早不宜迟：推荐信需要时间写，何况又得配合老师的时间。所以尽快起草你的推荐信，以便使你的推荐者有充裕的时间为你的推荐信效力。
2、提供充份的信息给推荐者：如果你要推荐者能掌握你的优点，你得提供充份的信息。自然，要尽量具体避免空洞地陈述。同时，你也该提供你申请学校截止日期给推荐者参考，以免推荐者耽误了你的申请。
3、推荐信的打字书信字体，宜选不同的型式，以示不同的推荐者。属需要圈选的表格者，可以直接以手稿填入。
4、在逻辑推理下，推荐者不可能知道或了解你的特质，请勿提及。譬如说，学生课外活动的表现就不适于平常教授正式科目的教授提及，除非教授也参与其中。又如其它课堂的表现，除非其它教授曾经提及过，否则不适合此科教授评论学生在其它科目的表现。再如，学生如何在图书馆查数据、写报告花费的时间，一般老师是不可能知之甚详，除非实在太特殊而略有耳闻，故也不适合在推荐信中提及。
5、推荐信的内容尽量简短有力：不要虚无空洞的形容词，勤劳、负责、认真、为人谦虚、诚恳等语句，不宜多引用，最好讲出具体事实，才不流于形式，尤其不要抄袭市面的书信范例，以免流于陈腔滥调，落入俗套。
6、如果可能的话，推荐者最好与你修的科目或学校相关。譬如说：如果你将来计划主修英文，最好推荐人之一是英文老师。又如，如果你申请常春藤名校（IVY LEAGUE SCHOOL），推荐者若也是常春藤名校出身，则其推荐信将更有力。
7、适当提及自己的“缺点”。一封推荐信如果阐述的完全是被推荐的同学的优点，不免让人觉得有粉饰之嫌，如果能恰当地加入一些“缺点”，不仅能令推荐信真实，还会通过“似贬实褒”，反而突出了被推荐人的特殊气质。
第三：带来参考范文一篇。
In capacity as Professor of Mathematics at Fudan University？I＇m writing to recommend Mr. Wang？Gesintosyour PhD program in Computer Science. I have known Mr. Wang since his sophomore year of college？and have acted as his thesis advisor and mentor. In my experience？he is a gifted and diligent student？and an admirably hard worker.
Wang is an impressive student because he has been forced to overcome the significant challenge of a serious illness during his freshman year. When I first met Wang in my Discrete Math class？he did not appear to be anything special to me. While his exam scores were good？they were not as high as I would now expect of him. What I didn＇t know then was that due to his illness？Wang was attempting to take all of the difficult early mathematics courses at one time？including Discrete Mathematics？Advanced Mathematics？Linear Algebra？and Possibilities. While most students found preparing for just one set of these exams difficult？Wang was overwhelmed by four of them. But in the end？he achieved an impressive score on the final exam？which made me conscious of his unusual determination he demonstrates when confronting difficult challenges.
Mr. Wang and I have often talked about a variety of mathematics and computer science concepts and problems. During these discussions？I always found him to be delightfully intelligent. Not only does he quickly understand the concepts and problems presented to him？he is able to analyze these problems and present solutions. But perhaps most important is that Wang＇s thinking is intensely rigorous. When looking at any question？he carefully scrutinizes it and if he finds any uncertain issues？he clears them up immediately. I believe this kind of thought is essential to become an excellent computer programmer.
Serving as his thesis advisor？I had a first-hand opportunity to observe the way in which Wang＇s mind works. In his senor thesis？Mr. Wang mainly discussed two challenging questions in regards to″ANN″. In our books in China？knowledge of ANN and its uses are very rare. Few people in China have studied this topic and consequently？the materials that are available on ANN are limited. Working on this difficult project？not only did Mr. Wang rise to the challenge？but he went above and beyond the call of duty to analyze his secondary sources and test them for accuracy in practice. In this way？he found mistakes in the book that we use. His diligence and hard work made me extremely proud of him.
Mr. Wang is an intelligent？motivated？and industrious individual. Teaching and advising him has been a delightful pleasure. I know that if given the chance to study abroad in America？he will arm himself to become a great programmer he dreams of being. He has the intelligence and background to achieve these goals - now all he needs is the opportunity. I ask that you look upon his application favorably and grant him a chance to study in your university.
