生日、聚会或者婚礼，英语的邀请函格式有什么？下面是小编整理的英语写邀请函的格式，欢迎阅读！
英文邀请信主要分为以下两种：一种属于个人类的信函，例如邀请某人共进晚餐、参加宴会、观看电影或者出席典礼等等。另一种邀请函则属于事务类的信函，一般是邀请参加会议、学术活动等等。
一、普通英文邀请函
第一种邀请信邀请的对象一般是朋友、熟人，所以内容格式上的要求都比较松，可以写得随便一些。只要表明邀请的意图，说明活动的内容、时间、地点等等。但既然是邀请信，那么就一定要在信中表达非常希望对方能够参加或者出席的愿望。这种邀请信的篇幅可以非常短。
二、正式英文邀请函
第二种邀请信一般由会议或学术活动的组委会的某一个负责人来写，以组委会的名义发出，而且被邀请者通常也是属于比较有威望的人士。因此，这类邀请信的措辞要相对正式一些，语气要热情有礼。
这一类邀请信通常要包括以下内容：首先表明邀请对方参加的意图以及会议或学术活动的名称、时间、地点;然后要对被邀请者的威望和学术水平等表示推崇和赞赏，表明如果被邀请者能够接受邀请，会给会议或者活动带来很好的影响;接着要说明会议或活动的相关事宜，最好是能引起对方兴趣的事宜;当然不能忘了表达希望对方能够参加的诚意;最后还要请收信人对发出的邀请做出反馈，如确认接受邀请。
三、英文邀请信的回复
无论是收到哪种邀请信都要复信，明确表示接受与否。而且无论接受与否都要对邀请者表示感谢。接受邀请的回信一般包含以下内容：首先感谢对方的邀请，并重述邀请信中的主要内容;然后愉快地表示接受邀请，并简要说明自己的打算;最后表示期待赴会和与对方见面的心情。
谢绝邀请的回信一般包含以下几方面的内容：首先还是要对对方的邀请表示感谢;然后具体说明自己无法接受邀请的原因，并对无法出席表示遗憾;最后表达自己的祝愿，即祝愿自己未能参加的会议或者活动能够顺利进行。下面是一封谢绝邀请的信，与上面的第二封邀请信相对应：

英语写邀请函的范文【三】
Write a letter to one of your high school classmates who is in a nearby city, and invite him/her to your city at this weekend. Some necessary details must be included. Do not sign your own name at the end of your letter, using “Li Ming” instead.
Sample:
Dear Linda,
We haven’t seen each other for six years after graduation. I am so glad to hear that you have graduated from UCLA and come back to work in Suzhou. If you are free this Saturday, please come to Shanghai and have a good time with me.
We can first go to the Century Park, where the flowers are all in blossom. Let’s go boating on the lake —isn’t it pleasant in the cool breeze? Then I will treat you to dinner at a western restaurant on Huaihai Road—it is small but really nice—I’m sure you will enjoy it. After dinner, let’s go to a concert—you are a music lover, aren’t you?
If you couldn’t come, please notify me before Friday. If you can, please tell me which train you will take and I will meet you at the railway station.
