论文答辩听不懂提问怎么用英语道歉

问：英语论文答辩，老师提出问题我确实不知道怎么回答，应该怎么向他说（用英文）？

1. 答：你说高纳的是毕业论文答辩吧？
   如果你确实不知道的话，你就直接回答“I don't know "就好了，免得你胡乱回答了一堆，却不着边竖念旦余扰际
   如果你没听清问题的话，可以说 “pardon?" 或 “May I beg your pardon?"
   记住：答辩时遇到自己未曾准备的问题时千万不要太紧张了^
2. 答：1.Teacher, I'喊悔m really don't know how to answer the question...Sorry.
   2.Sorry,teacher.(记肢渗孝得要历稿先举手哦~）May I beg your pardon?(如上的。）
3. 答：1.Sorry.
   2.Pardon?

问：如果听不懂老师的英语提问该如何机智化解尴尬

1. 答：先用pardon来暗示自己没有听清，让老师以为你并不是不懂
