I would like to know if I could ask for a casual leave of absence from March 23 to 27.
Yesterday I received a letter from my parents， who are both over 70， telling me that a big flood took place at my home village， causing serious damage to my house. As the only son of my parents， I should of back to assess the situation， and help them to get over these difficulties. Though I cannot stay at home for too long a time， I should at least make arrangements for repair work. I believe my relatives in the village and my neighbors will also come to help. Financially I have no difficulties.
I will call you at :30p.m. or you can call me at any time.
Dear MrMs XXX;
Today I'm writing to you to ask for a five-day leave, for I've got cold last night with carelessness.
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, eecially 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. Smith，
I am really sorry to tell you that I cannot attend the training course next Tuesday， because ny manager has appointed me to go on a 3-day business trip to Hainan. Will you please record the lecture for me to review later?
Thank you for your consideration.
