Question

【题目】--Let's go to Sunshine Street by taxi?

--It's only a ten-minute walk. We take a taxi.

A. needn't B. can't

C. mustn't D. couldn't

Answer 1

【答案】A

【解析】句意：——我们乘出租车去阳光街吧？——步行只需要10分钟，我们不必乘出租车。A. needn't不必；B. can't不能；C. mustn't表示禁止；D. couldn't不能，比can't更委婉一些。根据句意可知步行仅仅十分钟的路程，不是很远，所以不必乘出租车，needn't不必；故答案选A。
