在考研复试口语中，如果听不懂考官的问题，可以采取以下策略：
请求重复
Excuse me, I can’t quite follow you. Would you please say it again？
I beg your pardon？
Could you please repeat the question？
以反问形式弄清问题
Could I understand your question like this...？
I think you were asking me about... Am I right？
Well, let me see...
表达自己没听清
Sorry, I lost you. Could you repeat this question？
I'm so sorry, I didn't hear the question clearly. Could you please repeat it？
请求解释或澄清
There is a word in... sentence that I didn't understand. Could you tell me what it means？
Could you explain it a little bit？
保持冷静
不要因为紧张而害怕请求重复，这反而能让考官知道你有在认真听，并且有机会重新组织答案。
通过以上方法，可以有效应对在考研复试口语中因听不懂问题而产生的困扰，从而提高你的应答表现。
