请假条(written request for leave)是英语学习者必须掌握的常用应用文之一，它包括请病假(note for sick leave)和请事假(leave of absence)。请假条是用于向老师或上级领导等因身体状况不好或因某事请求准假的场合。
英文请假条写作需注意三点：
1.英文中请假条的写法和汉语请假条相同， 它一般由四部分组成，即时间、称呼、正文和签名。
2.一般而言，可认定请假条是一种简单的书信文体。请假条一般写在纸上，不用信封。其书写格式与书信有很多相似之处，是书信的大大简化。
3.请假条的特点是要求开门见山、内容简短、用词通俗易懂。

假如你是王立。昨天你和同学们去农场帮助农民们摘苹果，不幸(unluckily)从梯子上摔下来伤了腿，但伤得不重。医生让你在家里好好休息。因此，你向高老师请假两天(ask for leave for two days)。(2002新疆乌鲁木齐中考题)
(参考范文)
Sep.28
Dear Miss Gao,
I''''m sorry I can''''t go to school today. I helped the farmers pick apples with my classmates on the farm yesterday. Unluckily, I fell off the ladder and hurt my leg, but I wasn''''t badly hurt. The doctor asked me to stay in bed and have a good rest. So I ask for leave for two days.

(点评)这是一份采用书信格式写的请假条。日期是September 28, 日期写在正文的右上角。由于请假条的内容大多是当天、近几日因病或因事请假，所以不必写上年份；称呼是Dear Miss Gao，称呼写在左上角。请假条因是向上级请示，一般以Dear...,或My dear...,开头。有时可在Dear之后，用上Mr.或Miss等的称呼加上姓氏。不过，有一点仍要提醒大家，各种称呼后面一般都用逗号。正文谈了一件事：I fell off the ladder and hurt my leg, but I wasn''''t badly hurt. I can''''t come to school. I ask for leave for two days. 简洁明了，用词口语化。写请假条只要把请假的理由和请假时间说清楚即可。有的请假条为了说明其请假事由是真实的，在正文之后另起一行，写上I enclose a doctor''''s certificate.(我附上了医生证明。)；签名为Wang Li。签名(署名)写在右下角，签名(署名)上面一行可以写上Yours, Your student等字样，有时由于写条的人和收条的人彼此一般很熟悉，所以在称呼和签名上比较随便和简单。特别是在签名部分，有时可简单到只写个姓或只写个名就可以了。
第二篇：英文请假条范文
To: John Smith, Supervisor
From: George Chen, Accounting Department
Date: March 11, 2001
Subject: Casual Leave of Absence
John, I would like to know if I could ask for a casual leave of absence from March 23 to 27.
Yesterday I received a letter from my parents, who are both over 70, telling me that a big flood took place at my home village, causing serious damage to my house. As the only son of my parents, I should of back to assess the situation, and help them to get over these difficulties. Though I cannot stay at home for too long a time, I should at least make arrangements for repair work. I believe my relatives in the village and my neighbors will also come to help. Financially I have no difficulties.
I will call you at 1:30p.m. or you can call me at any time.
