参加正式会议的邀请信：

Dear SAVMA House of Delegates:  Spring on the Washington State University campus in Pullman is a special time of the year. The surrounding rolling hills of the Palouse area are serene waving seas of green wheat. Our area has been described as "Paradise" and "One of the Most Beautiful Places in the World" with great reason.  It is in this special locale--a small town with a major university and a superb College of Veterinary Medicine in world-class facilities with state-of-the-art equipment--that I invite the Student American Veterinary Medical Association to hold its 1999 Symposium at Washington State University. Faculty, staff, administrators, alumni, and friends look forward to the opportunity to provide western hospitality--from the opening session to the closing event--to all Symposium attendees. It will be perfect timing since 1999 is also the year in which the WSU College of Veterinary Medicine celebrates its centennial.  I am confident those attending the Symposium will remember their time at WSU for an exceptionally well-run event, for the beautiful environment, and for good feelings emanated by the good people who make our University and Pullman so very special.  Sincerely yours,  Samuel H. Smith  President [附译文]

尊敬的全美兽医学会代表：

春天对于坐落在普尔曼的华盛顿州立大学来说是一个特殊的季节。群山环抱的帕罗斯地区处处是青青麦浪，犹如一片宁静的海洋。我们这里素有“天堂”之称，将它称为“一个世界上最美的地方”也毫不为过。

正是在这样一个特别的地方——一个拥有一座重要大学和设施堪称世界一流，配备十分先进的兽医学院的小城——我向您发出邀请，邀请您前来华盛顿州立大学参加全美兽医学会1999年年会。本校全体教职员工，校友和朋友们都热切期册借此机会向各位与会代表表现他们西部人特有的热情，自始至终地为您提供优质的服务。1999年正值华盛顿州立大学兽医学院的百年华诞，真可谓双喜临门。

我相信，各位代表一定会在华盛顿州立大学度过一段美好的时光，记住这里优美舶环境，记住这里热情好客的人们，记住这一届办得特别好、办得令我们大学和整个普尔曼引以为荣的年会。

校长  塞缪尔  H．史密斯  恭邀尽管就本质而言正式与非正式的邀请信并没有什么区别，但从前文的示例可以看出，它们在形式上还是有差异的。正式的邀请信不仅在遣词造句和语言文体上比非正式的要正规，其表达方式也不完全一样，正式的邀请信比较注意文采，而且往往表现出更大的热诚。正式的邀请信不能就短短的几行，一般至少应该写满一页，信纸信封也比较考究。此外邀请信中还应详细写明各种具体的日程安排以及会议的具体内容，以便受邀请者进行全面的考虑，所以正式的邀请信有时有好几页。
