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。
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.
Yours, Wang Li
首先，假条的上方还是应该按照半正式的格式写上如下信息： To：假条是递给谁的 From：请假人
To: John Smith, Supervisor
From: George Chen, Accounting Department Date: March 11, 2015
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 go back to assess the situation, and help them to get over these difficulties. Though I cannot stay at home for too long, I should at least make arrangements for maintenance 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.
