考查情态动词。

can’t不能;mustn’t禁止;don’t助动词,不要;needn’t不需要,不必。

“Must…?”的否定回答是“No, …needn’t/don’t have to.”。

故选D。

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.B解析:B【解析】【详解】句意:——吉姆坐火车来吗?——我不确定,他可能开自己的车。

考查情态动词辨析。

A项,必须,一定,表示肯定推测;B项,也许,表示有可能;C项,需要;D项,应该。

根据回答部分I’m not sure.可知,此处并不确定吉姆是开车来还是乘坐火车来,所以此处是“可能”。

故选B。

【点睛】must意为“必须,应该”,可以表示主观上一定要做什么或者肯定推测。

例如:I must go home to look after my mum. This pair of shoes must be hers. may意为“可以,也许”,可以表示请求或者推测(无法断定)。

例如:May I come in? It may be hers,but I’m not sure. need意为“需要”,既是情态动词也是行为动词。

例如:You needn’t finish your homework right now. You need to tell him the truth. should意为“应该”,表示责任或者义务。

例如:You should finish practising playing the piano at first.4.B解析:B【解析】【详解】句意:从2013年3月23日开始,14岁以下的人禁止单独去迪士尼乐园。

考查情态动词词义辨析。

couldn’t不能;mustn’t禁止,不允许;needn’t不必;mightn’t可能不。

根据题意可知14岁以下的人禁止单独去迪士尼公园,表达一种强制规定,用mustn’t禁止,不允许。

故选B。

5.C解析:C【解析】【详解】句意:——你能告诉我一些在加拿大或者在美国的生活吗?——抱歉,我不知道,我来自澳大利亚。

could可以是can的过去式,但是在位于句首表示请求对方做某事的时候,表示礼貌而非过去时态。

can表示能力,表示能够做某事。

在空格一中,表示礼貌请求对方做某事,用could表示委婉语气;空格二中can’t表示回答者做不到,因为回答者来自澳大利亚而非加拿大或者美国。

故选C。

6.D解析:D【解析】【分析】【详解】句意:——Jenny,我们不需要给母亲买礼物,我们可以从上到下打扫房子。

——好主意,这是母亲节的一个特殊的礼物。
