我刚收到通知需于7号去参加考试,所以下周二我需请假一天,请悉知,谢谢!
书面说法可以这样:
Kindly noticed that I need 1 day off next Tue.(Sep.7) because I was just informed that I need to take the exam (that day). Thank you!
I just received the notice required to take the exam in the 7th, so I need to take a day off next Tuesday, please be kept informed, thank you!
I just received notice from 7 to test, so I must leave next day, please note, thank you!
