英语请假条应该怎么写?

假条的上方应该按照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
例如：
To:Peter Stone,
From:Lynn Chen,Financial Department
Date:April 2nd,2006
Subject:Casual Leave of Absence
This morning I received a telephone call from my dentist,urging me to come to his practice for immediate treatment of my teeth.I have been experiencing a stinging pain,depriving me of my sleep during the past fortnight.The situation could worsen,should infection occur.
Concerning my workload:As Wednesday is not as busy as the other weekdays,I think a one-day leave this Wednesday may be the best solution.I apologize for the inconvenience my absence from work may cause.
