邀請(qǐng)信分為兩種：一種屬于個(gè)人信函，例如邀請(qǐng)某人共進(jìn)晚餐、參加宴會(huì)、觀(guān)看電影、出席典禮等。另一種邀請(qǐng)信則屬于事務(wù)信函，一般是邀請(qǐng)參加會(huì)議、學(xué)術(shù)活動(dòng)等等。

　　一、普通邀請(qǐng)信

　　第一種邀請(qǐng)信邀請(qǐng)的對(duì)象一般是朋友、熟人，所以?xún)?nèi)容格式上的要求都比較松，可以寫(xiě)得隨便一些。只要表明邀請(qǐng)的意圖，說(shuō)明活動(dòng)的內(nèi)容、時(shí)間、地點(diǎn)等等。但既然是邀請(qǐng)信，那么就一定要在信中表達(dá)非常希望對(duì)方能夠參加或者出席的愿望。這種邀請(qǐng)信的篇幅可以非常短，下面以一封邀請(qǐng)看電影的短信為例：

Dear Jane,

We have four tickets for a famous film shown at Guangming Cinema, The Longest Day, Friday, the ninth. Will you join us? We'll be looking for you at eight sharp Friday night in front of the cinema, so don't disappoint us!

Warmest regards.

Alice


　　二、正式邀請(qǐng)信

　　第二種邀請(qǐng)信一般由會(huì)議或?qū)W術(shù)活動(dòng)的組委會(huì)的某一個(gè)負(fù)責(zé)人來(lái)寫(xiě)，以組委會(huì)的名義發(fā)出，而且被邀請(qǐng)者通常也是屬于比較有威望的人士。因此，這類(lèi)邀請(qǐng)信的措辭要相對(duì)正式一些，語(yǔ)氣要熱情有禮。

　　這一類(lèi)邀請(qǐng)信通常要包括以下內(nèi)容：首先表明邀請(qǐng)對(duì)方參加的意圖以及會(huì)議或?qū)W術(shù)活動(dòng)的名稱(chēng)、時(shí)間、地點(diǎn)；然后要對(duì)被邀請(qǐng)者的威望和學(xué)術(shù)水平等表示推崇和贊賞，表明如果被邀請(qǐng)者能夠接受邀請(qǐng)，會(huì)給會(huì)議或者活動(dòng)帶來(lái)很好的影響；接著要說(shuō)明會(huì)議或活動(dòng)的相關(guān)事宜，最好是能引起對(duì)方興趣的事宜；當(dāng)然不能忘了表達(dá)希望對(duì)方能夠參加的誠(chéng)意；最后還要請(qǐng)收信人對(duì)發(fā)出的邀請(qǐng)做出反饋，如確認(rèn)接受邀請(qǐng)。下面是一封邀請(qǐng)對(duì)方參加學(xué)術(shù)會(huì)議的信函：

Dear Professor Wang,

On behalf of the Ohio State University and the IEEE Computer Society, I would be very pleased to invite you to attend and chair a session of the forthcoming 2004 International Conference on Parallel Data Processing to be held in Bellaire, Michigan, from October 25 to October 28, 2004.

You are an internationally acclaimed scholar and educator. Your participation will be among the highlights of the Conference.

We sincerely hope that you could accept our invitation. As you know, this is the 10th anniversary of the Conference and we plan to make it a truly international meeting. We have accepted many papers from several foreign countries, including two from China.

If you can come, please let us know as soon as possible, since we have to prepare the final program soon. We are looking forward to your acceptance.

Sincerely yours,

Peter White

　　三、邀請(qǐng)信的回復(fù)

　　無(wú)論是收到哪種邀請(qǐng)信都要復(fù)信，明確表示接受與否。而且無(wú)論接受與否都要對(duì)邀請(qǐng)者表示感謝。接受邀請(qǐng)的回信一般包含以下內(nèi)容：首先感謝對(duì)方的邀請(qǐng)，并重述邀請(qǐng)信中的主要內(nèi)容；然后愉快地表示接受邀請(qǐng)，并簡(jiǎn)要說(shuō)明自己的打算；最后表示期待赴會(huì)和與對(duì)方見(jiàn)面的心情。下面是一封接受邀請(qǐng)的信，與上面第一封邀請(qǐng)信相對(duì)應(yīng)：

Dear Alice,

Thank you very much for your invitation. It will be great pleasure for me to join you on Friday for the wonderful film. I will arrive at the cinema before eight. I look forward to meeting you on Friday.

Thank you for thinking of me.

　　謝絕邀請(qǐng)的回信一般包含以下幾方面的內(nèi)容：首先還是要對(duì)對(duì)方的邀請(qǐng)表示感謝；然后具體說(shuō)明自己無(wú)法接受邀請(qǐng)的原因，并對(duì)無(wú)法出席表示遺憾；最后表達(dá)自己的祝愿，即祝愿自己未能參加的會(huì)議或者活動(dòng)能夠順利進(jìn)行。下面是一封謝絕邀請(qǐng)的信，與上面的第二封邀請(qǐng)信相對(duì)應(yīng)：

Dear Professor White,

Many thanks for your letter dated 15th August, inviting me to attend and chair a session of the forthcoming 2004 International Conference on Parallel Data Processing to be held in Bellaire, Michigan, from October 25 to 28, 2004.

Much to my regret, I shall not be able to honor the invitation because I have been suffering from a disease since this summer. I am firmly advised that it would be unwise to undertake any distant and long travel in the near future.

I feel very sad to miss the opportunity of meeting you and many others in the field of Computer Science. I wish the conference a complete success.

Faithfully yours,
