Letters of Invitation (邀请信)
在涉外交往、亲友通信的社交活动中，总免不了写请帖或邀请信。

邀请信分两种：一种是正式的，也叫请帖或请柬；一种是非正式的，就是一般的邀请信。

一般的邀请信与普通书信相同，虽不像请帖那样正规、庄重，但也要措辞婉转、诚恳有礼，使对方看后有亲切的感觉。

写好邀请信，需注意以下几点：
1. 邀请信一定要写得明确、完整，不可留下任何疑问使被邀请者捉摸不定。

要写明场合、地点、时间（年、月、日及钟点）。

2. 要写明请人来的目的。

2. 邀请者如有妻子，需将夫妇姓名都写上，对被邀请者也是如此。

3. 别人邀请你是对你的尊重，应该给予及时的、有礼貌的答复。

邀请信中常用的句型有：
I’d like you to come to dinner on Wednesday, May the eleventh.
Will you have a party with us at our home on Sunday, June the tenth, at six o’clock?
I do hope you can make it.
We are looking forward to seeing you both.
Example Letter of Invitation
Although many people now prefer the convenience of telephoning a response, it’s always better form to answer by note when invited by note.
