其實商務信函對於寫作者的基本要求不外乎幾點，語法準確、陳述事實、編排合理。在撰寫商務信函之時，由於細節頗多，不知道該如何抒發，那麼應該如何邏輯清晰地安排信函內容?Shirley Taylor在她的書(《Model Business Letters, Emails & Other Business Document》)中提出了基本的四點方案：
這個四點方案有助於我們在撰寫時保持清晰的頭腦，不漏掉重要的資訊，同時也可以保證一定的`邏輯。在進行BEC考試時，也可以使用這種方法，將要求表達的內容排個順序，然後不慌不忙地完成~
1. Opening or introduction 開頭或簡述
第一段陳述寫信的原因，基本明確信件內容。可包括以下內容：告知收到來信/提及一次見面或接觸/引出要談論的事情
Examples
Thank you for your letter of…
It was good to meet you again at last week’s conference.
We wish to hold out annual conference at a London hotel in September.
2. Central section (details) 主體部分(細節)
每部分內容獨立成段，細節陳述簡單清楚。最終應導向一個符合邏輯、自然而然的結論。
3. Conclusion (action or response) 結論(行動或迴應)
這部分應得出符合邏輯的結論：表明希望收信人採取何種行動/說明鑑於上述情況你將採取什麼行動
Examples
Please let me have full details of the costs involved, together with some sample menus.
If payment is not received within seven days, this matter will be placed in the hands of our solicitor.
4. Close 結尾
通常只需要簡單一行字，與信件內容呼應。
Examples
I look forward to meeting you soon.
I look forward to seeing you at next month’s conference.
I would appreciate your prompt reply.
Please call me if you have any question.
