英语请假条怎么写内容是生病了,不能去上学

To: Peter Stone,
From: Lynn Chen, Financial Department
Date: April 2nd, 2006
Subject: Casual Leave of Absence
Peter, I would like to know if I could ask for a casual leave of absence for one day on April 4th, this Wednesday.
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.
Thanks. I will call you at 1:30p.m. or you can call me at any time.
