事假英文请假条

马振华老师

  dear ms.xxx,

  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,

  xxx
