First, I'm sorry to bother you, but there's something I need to discuss with you.
If possible,our class hope we can move the English class ahead of the schedule.That is because many of us will go home while there're only a few buses.We will have some trouble if we can't catch the bus. We can move the class to Wednesday or Thursday,or just begin the class at 13:00 on Friday.We hope you can agree on our request. Thank you very much!
我做了一些改动,更符合你的要求.望采纳~
