根據這封推薦信，我們可以對推薦信的內容，結構和模式有非常直觀的認識。
第一， 從內容來看，推薦信包括以下幾個部分：
1. 推薦人和申請者之間的關係；
推薦人和申請者的關係一般有以下幾種：
1）師生關係（導師和學生，任課老師和學生，班主任和學生，系院領導和學生）；
2）上級和下屬關係；
3）同事關係；
4）實習單位領導和實習生的關係。
2. 兩人認識時間、經過；
3. 申請者的哪些素質給推薦人留下了深刻的印象（推薦人讚賞你哪些品質這是推薦的核心）；
4. 對申請者寄予什麼樣的希望（寄予的希望一般都會是希望申請者在申請的領域裡繼續深造，最終有所成就）。
第二，從整體結構來看,通常說來一封推薦信可以分別用以下三種結構來體現：
1. 總分總結構
2. 總分結構
3. 分總結構
而從單獨的段落來講，也可以是這三種結構。
但是由於申請材料眾多,為了讓評審的教授能夠在很短的時間內對你的特點有所印象，建議大家不管是整體的結構還是段落的結構都使用前面兩種：
1 總分總結構
2 總分結構。
這封推薦信在總體結構上採用了總分總的機構，在具體特點的推薦上採用了總分的結構。
第三，推薦信其格式有些模式可循，以下將針對各段提供模式作參考：
（一）抬頭可用的格式有：
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：這段可以提供最實質的內容。譬如，如果推薦人是教授，解釋學生在他門下所修的課程。
“(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”.”
接下來，教授寫一些有關申請人在課堂上的表現，如完成的研究計畫、實驗室研究、研究報告、考試的成績、課堂態度、討論課的參與等，舉出實例。
“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.”
如果推薦人是工作主管，首先一定要仔細陳述申請人的工作職責，並對申請者的工作表現做一評估。如果可能的話儘量列舉實例。
“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.”
第二段最後一段：可以提及申請人在班上（或公司里）的比較表現（譬如排名）：
“i was rate (name)’s academic ability as in the top 10% of his/her class.”
