【正确答案】To: Sam, Section Director
From: Li Ming
Subject: Leave of Absence
March 19
Dear Sam,
I would like to know if I could ask for one-day leave because of my frequent headache recently. I want to go to the hospital to have a physical examination.
I have already finished the task for this week and I promise to go back to work tomorrow on time. I'd be obliged if you approve my request.
Sincerely yours,
Li Ming
