单选题 Woman: Do you really think Prof. Green will make you re-do the entire experiment?
Man: I don't know. I'll cross the bridge when I come to it.
Question: What's the man planning to do?

【正确答案】 D
【答案解析】[解析] 此题考查对习语的理解和运用。“cross the bridge when…come to it”“到了桥边再过桥”,意思是“走着瞧,到时候再说”。所以D项更符合男士的意思。A项意为“推迟现在应该做的事”。C项意为“时刻听从教授的指示”。
