     现代社会。社交很重要。写一篇英文邀请函也是证明一个人礼貌与素质的一种表现！所以，以便好的英文邀请函，可以绝对别人对你的看法，甚至可以影响到社会中的地位。

     我认为，英文邀请函可以分为两种。一种为正式的，正式的邀请函形式比较固定，内容也比较具体。一般会是这样的，请看示例：开头应该先是Dear  Mr/Miss  ，然后就是正文，我麽开以这样开头，It  is  our  honor to invite you to …然后就可以说具体内容了，最后说明时间，地点日期 然后写上署名。非正式的邀请函就简单了，它的格式相对来说不那么严格。可以使用第一人称，称呼语气上也比较自由。其实也和正的邀请函区别不大。可以自由些比如说开头可以写，日期 ，地址等等…份额知政事的不用太注意格式的变化，随意就好。但是也应该注意语言的运用。
