根据这封推荐信，我们可以对推荐信的内容，结构和模式有非常直观的认识。
第一， 从内容来看，推荐信包括以下几个部分：
1. 推荐人和申请者之间的关系；
推荐人和申请者的关系一般有以下几种：
1）师生关系（导师和学生，任课老师和学生，班主任和学生，系院领导和学生）；
2）上级和下属关系；
3）同事关系；
4）实习单位领导和实习生的关系。
2. 两人认识时间、经过；
3. 申请者的哪些素质给推荐人留下了深刻的印象（推荐人赞赏你哪些品质这是推荐的核心）；
4. 对申请者寄予什么样的希望（寄予的希望一般都会是希望申请者在申请的领域里继续深造，最终有所成就）。
第二，从整体结构来看,通常说来一封推荐信可以分别用以下三种结构来体现：
1. 总分总结构
2. 总分结构
3. 分总结构
而从单独的段落来讲，也可以是这三种结构。
但是由于申请材料众多,为了让评审的教授能够在很短的时间内对你的特点有所印象，建议大家不管是整体的结构还是段落的结构都使用前面两种：
1 总分总结构
2 总分结构。
这封推荐信在总体结构上采用了总分总的机构，在具体特点的推荐上采用了总分的结构。
第三，推荐信其格式有些模式可循，以下将针对各段提供模式作参考：
（一）抬头可用的格式有：
Dear Sir/Madam/To Whom It May Concern:
（二）第一段：引文句子。可以引用如：
“It is a pleasure to recommend to you (name), a former student of mine at (name of university).”
“I am very happy to have this opportunity to recommend (name), who is presently applying for admission to your graduate (or undergraduate) program in (name of program).”
“I understand that (name) is applying for admissions to your graduate (undergraduate) school, and has requested that I write this letter of recommendation for her/him.”
“In my capacity as professor at xxxx University, I have known xxx for three years, as both his/her advisor and professor.”
（三）第二段：这段可以提供最实质的内容。譬如，如果推荐人是教授，解释学生在他门下所修的课程。
“(name) took two of my courses during the 1998-99 academic year, as follows; “xxxxx” and “xxxxx”.”
“(Name) was enrolled in three of classes from September 1998 to June 1999 “xxx” and “xxx”.”
接下来，教授写一些有关申请人在课堂上的表现，如完成的研究计划、实验室研究、研究报告、考试的成绩、课堂态度、讨论课的参与等，举出实例。
“In my class (es), (name) did excellent work. She always listened attentively, participated actively in class, and handed in very good written assignment.
“In particular, his/her research paper on (topic) was of exceptionally high quality, and showed that s/he fully understands and has a strong background in his/her field.”
如果推荐人是工作主管，首先一定要仔细陈述申请人的工作职责，并对申请者的工作表现做一评估。如果可能的话尽量列举实例。
“When (name) held the position of (job title) in this company she was one s/he was one of my best employees. His/her job responsibilities included (describe them), and s/he carried out his/her duties with exceptional skill and professionalism.”
“S/he not only did his/her own work, but also helped other employees, and made many valuable contributions to the efficient running to our firm.”
第二段最后一段：可以提及申请人在班上（或公司里）的比较表现（譬如排名）：
“I was rate (name)’s academic ability as in the top 10% of his/her class.”
