请假条(asking for a sick leave or a business leave)一、请假条的基本构成请假条包括病假条(sick leave)、事假条（因公business leave和因私casual leave）、续假条(extension of leave )等。
写请假条主要把请假原因和请假时间写清楚，请假的理由要讲充分。
同时也要注意内容要简单明了，开门见山说明情况，不必赘述。
如果有证明请假原因的证据，如医生证明、电报等最好随条附上。
请假条是便条的一种，主要用于因病或因重要事情须向领导请示批准某一特定时间的假。
应包括以下四部分内容： (1)日期日期通常应在正文右上角，因请假条涉及到的是最近时间内的事情，故可直接用几月，几日或星期几来表示，如april 10或10 april或thursday。
(2)称呼称呼常用常规信中的称呼语，如dear?，mr.?，professor?，dr?等。
(3)正文正文是请假条的核心部分，主要涉及到请假原因、请假时间，结尾时需用—些表示感谢或请求批准的话语。
切记理由要充分，在必要时应附上相应的证明。
(4)结束语与署名结束语常用yours faithfully 或 yours sincerely 或 yours truly等。

)concerning my workload: as wednesday is not as busy as the other weekdays, i thinka one-day leave this wednesday may be the best solution. i apologize for theinconvenience my absence from work may cause. (在假条的最后一段，要写上你希望获得准假的请求，或者具体等候答复的时间。
) thanks. i will call you at 1:30p.m. or you can call me at any time. yoursjames wang二、常用句型1、起首用语请假条中起首句常用来说明请假原因或请假时间，常用句型如下：i’d like to apply for three days leave of absence，starting from?，and finishingon? i am writing to ask for sick leave of?days，starting from?to? i’m sorry i can’t attend the meeting because／as? owing to?／as?，i shall be unable to? 2、结尾常用语请假条中结尾用语常用来表示感谢、请予批准等。
常用句型如下： i should be veryobliged／grateful if you grant me the leave．i hope you will grant me theleave． hoping you will excuse my non-attendance．i’ll certainly do my best to make up?once／as soon as? now i enclose a doctor’s certificate／a medical certificate from／issued by thedoctor． now i enclose the telegraph from my father．三、范文分析[范文] 事假条aapril 25thsecretary frick，as my brother is moving to canada tomorrow，i shall be very much obliged if youwill grant me my application for one day’s leave tomorrow．yours respectfully robin ford[分析] 这是robin ford给秘书frick的一张请假条。
其中包括日期(april 25)、称呼语(secretary frick)、结束语(yours respectfully)、署名(robin ford)以及核心部分——正文。
就正文而言，一个主从复合句就给出了请假条正文所应包含的所有的信息，如请假理由：“my brother is moving tocanada tomorrow，请假时间区间为tomorrow，表示感谢的话语：“i shall be very muchobliged，请求批准的话语：you grant me application for one day’s leave”。
从这些方面来看，该请假条体现出了请假条简单明了这一特点。
正文开头以“as?”引导的原因状语从句引出请假理由，这样的开头使人一目了然。
[范文] 病假条(english 2nd year，class b) april 21(to department office) ms. smith，owing to a severe headache, i shall be unable to attend classes today. i enclosea medical certificate from the doctor. hoping you will excuse my non-attendance. yours respectfullyli ming[分析] 该请假条从基本格式到内容都符合请假条的要求，包括请假条中的信头(系、年级、班级和写假条的日期)，收假条部门以及收假条人名，其中的系、年级、班级和收假条部门也可省略，直接用最简单的请假条格式，从内容中可推断出写请假条人与收请假条人是师生关系。
正因如此，请假人写上了“i enclose a medical certificate from the doctor”以示请假理由并非借口，以介词短语“owing to?”引出请假理由，以句子“i shall be unable to attend classes today引出了请假时间区间即today，开门见山，直截了当。
