一、选择题

1.C

解析:C

【解析】

【分析】

【详解】

句意:——我可以喝一些酒吗?——不,你不可以。你以后必须开车回家。shouldn't不应

该,needn’t不必,mustn’t禁止,may not可能不。根据You have to drive home later.可知,你必须开车回家,因此表示你不可以喝酒,故用mustn’t。故选C。

2.C

解析:C

【解析】

【详解】

句意:--听! 狼在叫! --它不可能是狼,因为狼从来不会在这个时候出来。

A. mustn’t禁止;B. needn’t没有必要;C. can’t不可能;D. don’t构成一般现在时的否定句。根据“because a wolf never comes out at this time因为狼从来不会在这个时候出来”,可推断它不可能是狼,故选C。

【点睛】

情态动词表推测的用法:can表示“可能”;can’t表示“不可能”;may表示“可能”,must表示“一定”,注意mustn’t表示“禁止”不表示推测,表示否定推测要用can’t.

3.A

解析:A

【解析】

【分析】

【详解】

句意:看这个标志!上面写道“禁止吸烟!“你不能抽烟。这是危险的。mustn’t 禁止,不允许;ought not to不应该,不应当;needn’t不必;don’t have to不必。根据“No Smoking!”可知此处禁止吸烟,所以选A。

4.C

解析:C

【解析】

【详解】

句意:你已经完成了大部分工作,所以你明天不必这么早就开始工作。你可以9点来。

本题考查情态动词。can't不可能,mustn’t禁止,needn’t不必,couldn’t可能不。根据You

have finished most of the work可知,你已经完成了大部分工作,因此明天不必这么早就开始工作,因此用needn’t,故选C。

5.A

解析:A

【解析】

【详解】

句意:—温迪现在在教室吗?—我不确定。她可能不在那里,十分钟前我在图书馆见过她。

考查情态动词表推测。may not可能不;must not一定不要;shall not将不会;would not将要、会、就会,表示虚拟、假设、条件等。根据回答句“I’m not sure”,可推测后句应该是说:她可能不在那里。是对现在情况的推测,may not“可能不”。故选A。
