【正确答案】To：Sam, Section Director
From：Li Ming
Subject:Leave of Absence
March 19
Dear Mr. Sam,
I would like to know if I could ask for one-day leave because of my usual headache recently. I want to go to hospital to do a body check.
I have already finished the task for this week and I promise to go back to work tomorrow on time. I will be very much obliged if you grant me the leave.
Sincerely yours,
Li Ming
