Dear Mr Li,
I’m sorry to tell you that I have to ask for sick leave for the whole afternoon class. Because I have a heavy headache now and feel very sick. I think I have to ask for sick leave to go to hospital for medicine. I will attend the next day classes on time.
Dear Prof. Wang，
I am very sorry to apprise you that I am unable to attend school today owing to a bad cold. I enclose doctor’s certificate and ask you for sick leave of three days.
Dear Mrs Brown，
My grandma suddenly fell ill last night. My parents happened to be out on business. I had to send her to hospital and look after her. I 'm writing to ask for leave of absence for three days.
I shall be very grateful if you will grant me my leave. I '11 try my best to make up my lessons missed during my absence as soon as I get back from leave.
4th March Dear Mr. Li,
I am writing to ask for a sick leave of three days, starting from today to 6th March, both days inclusive. (adj. 用于n..之后BrE 所有数目或首末日包括在内的.) I enclose the doctor’s certificate and hope that you will grant me the leave.
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.
I am going back to my hometown to join my brother's wedding, so I want to ask for 3 days' leave, I am sorry I can't take your classes from 14th to 16th, I will try my best to learn the lessons well. Thank you!
Dear Mr/Ms Wang
I was unable to come to 1st and 2nd period today.Due to the rain yesterday, I was wet and had temperature at night. The doctor adviced me to rest for several days and after my recovery, I will attend school as soon as possible.
I am sincerely sorry about the inconvenience. However, I would like to have your permission. Also, afterwards I would phone you and there's the certificate by the doctor.

Subject： Casual Leave of Absence
William， 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 1：30p.m. or you can call me at any time （3218）。
I won't be able to attend school for today and tomorrow because i just got a call from my sister saying that our mother fell ill and is going to be in the hospital for few days. I am very sorry for the fact that i'll be absent for two days because i have to go and take care of my mother, but i'll be back in school as soon as she gets better and catch up with the rest of the students.
Thank you for your consideration.
