单选题 Speaker A: Well, you can see dolphins ahead of you if we don't run out of fuel.
Speaker B: Is that right? ______
Speaker A: Maybe about another two and a half hours.
  • A. I couldn't wait to see them.
  • B. When would it be?
  • C. How long will it take?
  • D. How fast should we go?
【正确答案】 C
【答案解析】[考点] 根据应答推断话语 [解析] 说话人A的回复Maybe about another two and a half hours(也许还要大约两个半小时)显示的是一个时间段，而不是一个时间点，由此可知，说话人B的话应与时间有关，可排除表示急迫心情的A项和表示速度的D项。B项问题的恰当回复应是一个时间点，如两小时后或两点钟，因此从答复来看，B项也是错误选项。正确答案为表示时间段的C项。
