怎样写英文请假条Written Request for Leave

春天是感冒，包括很多传染病的多发季节，万一得了病，如何用英语写请假条呢?请假条(written request for leave)，包括病假条(note for sick leave)和事假条(leave of absence)。

一般格式为：

To：某某(假条是递给谁的)

From：某某(请假人)

Date：某年某月某日(写假条的日期而不是请假的日期)

Subject：标题(写上请假字样)

参考例文

To： James Zhao， Manager

From： Kaven Han， assistant

Date： March 27th， 2006

Subject： note for sick leave

Dear Mr. James Zhao，

I would like to know if I could ask for a sick leave for one day on March 29th.

I just caught a cold， then I hope I can go to hospital that day. And I will try my best to finish my work on March 28th.

Many thanks. Im looking forward to your kind answer.
