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 findthe 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'1l do a good job and both of us will be grateful.
thanks. your kind permission will be greatly appreciated.

An Application For Annual Leave
To: Mr. John Smith， General Manager
From: George Chen， Accounting Department
Date: January 22， 2003
Subject: Application for annual leave
Dear Mr. Smith，
I would like to apply for an annual leave from January 25th to 31st.
As you may know the Spring Festival is falling on February 1st this year. It's the most important holiday in China and offers the best occasion for family reunion. However， over the past 3 years I missed the reunions due to tight work schedule. Now that I have wrapped up my work for this year， I would like to go back to my hometown to pay filial piety to my parents and help my sole brother prepare his wedding on January 28th.
It's indeed double happiness for my family that I would like to be part of. Coupled with the official holidays for the Spring Festival， I will have two weeks off which will definitely gear me up for better work in the new year. I'm looking forward to your kind answer.
dear ms wang，i beg to apply for seven days'leave/one week's leave of absence from the 4th to 10th of this month.because my father is seriously ill now，so i want to return home to see him.
to support my application，i enclose the fax my sister sent.
