在考研复试的英语问答中，如果你不确定答案，可以采用以下几种策略：
1. 保持自信，微笑回应：“I'm sorry, I'm not quite sure about that specific answer. However, I can share my thoughts on the topic. [简述你的理解或相关知识点。]”
2. 请求时间：“Could I have a moment to think about that? It's a bit complex, but I do have some ideas.”
3. 转移话题：“That's a great question, but may I redirect the focus to [另一个相关的问题或话题]? I'm more comfortable discussing that area.”
4. 承认不足，展示学习能力：“I'm not certain about the answer, but I'm eager to learn and improve. Could you provide some insight into that topic?”
5. 诚实表达：“I'm not sure about the answer to that question, but I'll do my best to research it further after the interview.”
