信函和备忘录是商界广泛采用的形式

The overall appearance of a letter, memo, or report affects, to a considerable extent, the reception of the intended message. Attractively displayed messages create a positive image, leaving an impression on the addressee of courtesy, care, and competence to the work involved.

信函，备忘录或者报告的表现形式在很大程度上影响着收件人的接收。有吸引力的版面设置可以构造一个积极的形象，给收件人留下一个礼貌谨慎的印象并且使你的内容很有力。

A couple of acceptable formats for letters are commonly adopted in current business world, preference of one over another is purely a matter of personal taste. Despite their apparent differences, they must serve the same purpose: the recipient should be able to tell - at a glance - when, where, and by whom the letter was written, exactly for whom it is intended, and how its writer should be addressed in reply.

信函有两种可接受的格式目前被商界广泛采用，偏爱其中一个则是个人爱好。尽管它们有明显不同，它们的目的是一样的：接收者应该能马上获得时间，地点，和写信人是谁这些信息。尤其对那些特定收件人，一定要注明回信地址。
