Dear Ms.Riddle，
I would like to know if I could ask for a casual leave of absence from your Oral English class this Wednesday morning.
Yesterday evening I got a phone call from my cousin, who is now running a small firm in suburbs of this city . He needs an interpreter for two days but cannot find the most reliable person， so he wants me to have a try. Personally ， I regard this as a golden opportunity to put what I have learned in your class into practice， but I need your permission of absence . If you think I may go and help him get over the difficulty， I am confident that I ll do a good job and both of us will grateful.
Earnestly yours，
Sam
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
