在面对考研复试英语问答时，如果你不确定答案，可以采取以下几种策略：
1. 表达不确定但愿意尝试的态度：“I'm not entirely sure about that, but I would like to give it a try and see if I can provide a reasonable answer.”
2. 转移话题，请求时间思考：“I appreciate the question, but it requires some thought. Could I have a moment to consider it?”
3. 诚实表达：“I'm sorry, I'm not sure about the answer to that. However, I can certainly discuss the topic and share my understanding of it.”
4. 引导话题到已知领域：“I'm not sure about the specific answer, but I do know about [related topic]. Would it be possible to explore that instead?”
5. 提出假设性回答：“I'm not certain, but I would speculate that [guess] might be the case. Would that be a reasonable assumption?”
