订购信

订购信一般用于订购某种货物或机票、车票，属于事务信件。在书写订购信的时候，最重要的是要清新明白地说明所要订购的对象的数量、价格、规格等等，如果是机票、车票等，则须说明出发地、目的地、出发时间等。此外，写明你自己的名字、地址、邮编，以及你期望的送货方式等也是非常重要的。要避免写冗长的句子，因为此类信函以传达信息为主，所以能让对方明白你的意图是最重要的。

下面是一封订购飞机票的信函：

Dear Sir or Madam:

I am on an urgent mission and want to get to Hong Kong as soon as possible. Please reserve for me a seat in the plane leaving Guangzhou for Hong Kong at 8 a.m. tomorrow. A seat by the window in the economic section is preferred. I shall be very grateful if you would deliver the ticket to Room 418 of the Baiyun Hotel where I am staying.

If there is no seat available at 8 a.m. tomorrow, please inform me as soon as possible, so that I can change a flight.

Thank you very much!

Yours faithfully,

Steve Brown
