Dear Mr/Ms XXX;
Today I'm writing to you to ask for a five-day leave, for I've got cold last night with carlessness.
This morning my mother took me to see the doctor,who told me to stay in bed for some days. So I am very sorry to be absent from school, especially your interesting lessons. I'll be sure to make up for the missed lessons after I recover from the illness.
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.

Dear Mr. Black:
I am terribly sorry to informyou that I am unable to go to school today owing to a severe headache. I enclosea certificatefrom the doctor who is attending on me, as she fears it will be two days before I shall be able to resumemy study. Could you kindly excuse my absence on Monday and Tuesday? Thanks.

A friend of yours, Zhang Peng, made a long distance call from Shanghai this morning while you went out. He asked you to book an air ticket for Hebei at 2: 30 a.m., February 8, and make a reservationfor hotel room tonight. I am sorry that I can’t pass on the message to you in your presence, because I was ordered to do something urgent.
