訂購信在考研英語作文中也較常用到，一般用於訂購某種貨物或機票、車票，屬於事務信件。在書寫訂購信的時候，最重要的是要清楚明白地說明所要訂購的對象的數量、價格、規格等等，要避免寫冗長的句子，因爲此類信函以傳達信息爲主，所以能讓對方明白你的意圖是最重要的。以下是應屆畢業生職場英語網站欄目爲大家整理的信件範文，供大家學習參考。
Directions:
You are preparing for an English test and are in need of some reference books. Write a letter to the sales department of a bookstore to ask for:
1)detailed information about the books you want,
2)methods of payment,
3)time and way of delivery.
Dear Sir or Madam,
(寫作目的) I am writing for information about test preparation materials for the IELTS test.
(改寫三點提綱) I wonder if you have a vocabulary book covering the words required for IELTS, as well as past examination papers with keys and model essays. Besides, how should I pay for these books——by cash, cheque, or any other means? If possible, I would like to use my credit card. Finally, how will these books be shipped and when is the approximate time I can receive them? The express mail is preferable if the additional charge is not much.
(黃金句) I would appreciate it if you would send me a reply at your earliest convenience.
Yours sincerely,
Li Ming
尊敬的.先生或女士：
我寫信是爲了詢問關於雅思考試的考試準備資料的信息。
我想知道您是否有一本包括雅思考試所需詞彙的詞彙書，以及有答案和範文的歷年試卷。其次，我應該如何付款——通過現金、支票還是其他任何方式?如果可能的話，我想使用信用卡。最後，這些書如何送來，我大約什麼時間可以收到?如果額外費用不多的話，請您最好使用特快郵件。
如果您能儘快答覆，我將非常感謝。
您真誠的，
李明
