Question

【题目】一Must I leave now? It's still raining hard outside.

一No, you . You can wait till the rain stops.

A. don't have to B. couldn't C. can't D. shouldn't

Answer 1

【答案】A

【解析】句意：-我必须现在离开吗？外面还在下着大雨。-不，你不必，你可以等到雨停。don’t have to不必，没有必要；couldn’t不能，是can的过去式；can’t不能；shouldn’t不应该。一般疑问句中用的是must，否定回答应用needn’t或者是don’t have to。故选A。
