Dear Miss Zhang,
I am sorry that I am unable to attend the morning classes because of a bad cold and high fever. Enclosed is a certificate from the doctor who said I must stay in bed today. I will go back to school as soon as I recover.
Yours respectfully,
Annie
Dear Sir or Madam: Dear Mr Li/Miss Li/Mrs Li,
I beg to apply for two days’ leave/a week’s leave/7 days’ leave of absence (请假) from the 7th to 8th of this week. Because I was ill, I want to return/go home to see the doctor.
To support my application, I herewith/enclose the sick leave certificate.
I should be very much obliged if you will grant me my application. As regards the lesson to be missed during my absence, I will do my best to make them up as soon as I get back from leave.
Yours respectfully, Li Min
Dear Miss Gao,
I'm sorry I can’t go to school today. I helped the farmers pick apples with my classmates on the farm yesterday. Unluckily, I fell off the ladder and hurt my leg, but I wasn''''t badly hurt. The doctor asked me to stay in bed and have a good rest. So I ask for leave for two days.
Your student
Wang Li
