便箋(Short Note)屬于英文信函的一種，實際是一種簡短信函，形式比一般書信簡單，大多使用非正式語體。便箋經常用于熟識的朋友、同事之間，因而臨時性強，內容簡短，格式簡便。寫便箋時需要寫清以下內容：時間、人名及事由。

　　從格式上來講，便箋的稱呼和結尾謙稱部分是比較隨意的，可以直接寫上對方以及自己的名字，省略類似于Mr., Dear, Sincerely yours等禮貌用語。時間的寫法也相對較隨意，寫星期幾或者月日都是可以接受的，同時還可以具體到幾點鐘。

　　便箋的內容一般是涉及請假、預約、通知、訪友不遇留言、接電話留言等等，下面我們列舉一些例子供大家參考。

　　1. 請假條

　　請假條可由別人代寫，也可由請假人自己寫。無論采取何種形式，其內容必須包括請假事由和期限，必要時還需附上醫生的診斷或其他的可以證明請假事由的書面材料。

　　Dear Mr. Black:

　　I am terribly sorry to inform you that I am unable to go to school today owing to a severe headache. I enclose a certificate from the doctor who is attending on me, as she fears it will be two days before I shall be able to resume my study. Could you kindly excuse my absence on Monday and Tuesday? Thanks。

　　Peter

　　2. 約會條

　　約會條主要用于邀朋友相聚等，內容必須包含約會的事由，如果已經確定了時間和地點，則應將具體時間和地點寫在便箋上。

　　Andy,

　　Fred is now with us. He is going to New York tomorrow morning to pursue his graduate study and we will not be able to see him for a long time. We are having a dinner party at 7 p.m. this evening at my home. It would be nice if you could come over and see him。

　　Michael

　　3. 電話留言條

　　電話留言(telephone message)便條是在給別人打來電話時，該人不在場，你替他或她接了電話后留給該人的字條。寫這種便條時，首先要告訴對方誰打來的電話，再把電話內容轉告清楚。

　　Ms Wang,

　　A friend of yours, Zhang Peng, made a long distance call from Shanghai this morning while you went out. He asked you to book an air ticket for Hebei at 2: 30 a.m., February 8, and make a reservation for hotel room tonight. I am sorry that I can’t pass on the message to you in your presence, because I was ordered to do something urgent。
