告诉大家如何写出正式的邀请函
1. express that you are looking forward to seeing the person. 表达你殷切的邀请之情。
2. do not use abbreviations and do not use contractions (don't; we'll) except for name titles, such as mr., mrs., etc. 在信件中不要使用缩写和简写（名前称呼除外）。
3. if dinner will be served, state two separate times: the time people can start arriving and the time dinner will be served. 如果您的聚会中包括正餐，请把正餐的时间另外标明，以便客人能够在正餐前赶到。
4. if guests are not from your local area, include a map to the location of the event. 如果客人不熟悉赴宴的路线，最好附上地图或是简单的路线指示。
5. if you are inviting someone to speak at a conference, your invitation should include the following information: 如果是正式会议等的邀请，您可能会邀请某些客人在会议上演讲或致词，那么就要在邀请函中再包括以下要点：
- type of audience; 听众对象
- the type of speech, topic, and how long the speech should be 演讲类型及时间长短
- any accommodations that will be made, including lodging, meals, and transportation; 为演讲客人安排的住房、三餐以及交通设备
- the name of the contact person along with phone numbers and addresses where the person can be contacted 相关联系工作人员的电话等。
一般说来，书写邀请函的注意事项就是这些。邀请函分为三种：正式的，商务的和私人的。
