英语论文答辩没听清老师问题

你说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^

Sorry but I can't follow you.

先用pardon来暗示自己没有听清，让老师以为你并不是不懂在老师重复一遍问题后，可以说all right， as we all know that this question is so controversial that may there be so many different answers. i'd like to think for a while, and you can ask somebody else for now.然后就听别人回答就好了
