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，也是高考要求掌握的写作话题之一，它包括请病假（note for sick leave）和请事假（leave of absence）。请假条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。
一、写作指南：
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，在高考中，时间、称呼和签名一般会给出。全文一般分为三段。
2.请假条是一种简单的书信文体，其书写格式与书信有很多相似之处，是简化的书信，要有合适的开头和结尾句，同时具备一般书信的人称和时态等特点。
3.请假条要求开门见山、内容简短、用词通俗易懂，口语化。
二、常用句式：
1.i'mwriting to you to ask a sick leave.我在给你写信请病假。
2.i ask you for sick leave of three days.我请3天病假。
3.i'm sorry that i can't go to school today，so i want to ask for two days of sick leave.很抱歉今天我无法上学了，所以我想请两天病假。
4.i wonder if you could give me your permission.你是否同意我请假呢。
5.i hope you can approve my leave.望准假！
6.your kind permission will be greatly appreciated.承蒙惠准，感激不尽。
7.i'11 go back to school as soon as i am well enough.and i'11 do my best to make up for the missing lessons during my absence.我病一好了就会尽快回校。并且我会尽我所能去补上所缺的课程。
8.sick leave 病假a casual/absence leave事假
9.i am very/really/terribly/extremely sorry to tell you that i cannot attend your english classes today.很抱歉我今天不能上您的英语课。

11.i want to ask for four days'leave from tuesday to friday.
我想请假4天，时间是从周二到周五。
12.i enclose a doctor's certificate.我附上了医生证明。（注意：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，写上这句）
三、写作模板：
提出请假+阐述请假事由（并致歉）+希望获准
请假条全文一般分为三段。
第一段：开门见山，有礼貌地提出请假。中心明确，写清楚请假的时间及日期。
第二段：简单明了陈述请假的原因事由。叙述清楚明白，并尽可能表达因此带来的工作
或学习上的不便的歉意。
第三段：希望获准，或等候答复。写上希望获得准假的句子，或者具体等候答复的时间。
