The difference between letters of reference and recommendation is slim. A recom- mendation is an endorsement while a reference is simply a report. A recommendation is persuasive while a reference verifies facts. Both types of letters start out the same. Each should include:
(1) a statement of the letters purpose;
(2) an account of the duties performed by the applicant or of the applicant's general qualifications.
A letter of recommendation usually adds a concluding statement specifically recommending the applicant for the particular position.
证明和推荐信之间的差别很小。推荐信是一种认可，而证明只是一份报告。推荐信是有说服力的，而证明只是验证事实。两种类型的信件都是相同的。各应包括：
（1）信函目的声明；
（2）申请人履行的职责或者申请人的一般资质的说明。
推荐信通常加上一个结论性陈述，特别推荐应聘者担任特定职位。
