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.
Yours, Wang Li
比较正式的商务型假条
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
Date：写假条的日期(注意不是请假的日期) Subject：写上请假字样(事假或病假)
其次，在您的请假信第一段，应该开门见山但是有礼貌地提出请假。第一段要中心明确，写清您要请假的日期。
然后，在假条的第二段，您应该简单明了陈述请假的原因事由。注意叙述清楚明白，并尽可能表示对此带来工作不便的歉意。
接着，在假条的最后一段，应写上您希望获得准假的句子，或者具体等候答复的时间。

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 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.
