你最好把它扔掉。
考查had better和人称代词宾格。
throw away意为“扔掉”,根据所给空前面的had better后面接动词原形,排除B和D,由milk是不可数名词,所以用it来代指,排除C,故选A。
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】【详解】句意:——我驾照考试又失败了。
——别担心。
就像天气一样,生活也不可能一直是美丽的。
考查情态动词。
can't不可能;needn't不必;shouldn't不应该;mustn't一定不能。
根据句意,应是不可能一直美丽。
故选A。
4.B解析:B【解析】【分析】考点:考查动词。
【详解】试题分析:句意:我希望你能来参加我的生日聚会。
hope to do sth希望做某事;hope that 从句,希望……。
但不能说hope sb to do sth;从句主语you,所以谓语动词不能用comes单数形式;come是实意动词,前面不能用are;所以选B。
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。
6.A【解析】【详解】句意:——你的房子必须现在打扫吗?——不,不必。
可以今天下午打扫。
考查情态动词辨析。
must 必须;may 可以;can 能。
根据下文回答needn't 不必,可知,上文的一般疑问句中用助动词must表示“必须”。
故选A。
【点睛】情态动词must表示“必须”,由must引起的疑问句中,肯定答语用must,否定答语用needn’t或don’t have to,表示“不必”。
7.D解析:D【解析】【分析】【详解】句意:-我们现在能过马路了吗?-不,我们不能,我们要等到交通灯变绿。
couldn’t不能;needn’t不需要,不必;shouldn’t不应该;mustn’t禁止,不要。
根据句意We have to wait until the light turns green可知,在红灯的时候是禁止过马路的,因此这里的语气比较强,故应选D。
8.D解析:D【解析】【分析】【详解】句意:——妈妈,我今天必须完成作业吗?——不,你不必这么做。
明天是星期天,你今天可以休息一下。
考查情态动词辨析。
A. shouldn’t不应该,表建议;B. mustn’t一定不,表禁止;C. can’t不能,表示不允许;D. don’t have to不必,指没有必要。
回答must引起的一般疑问句,如果要作否定回答,一般是用needn’t(不能用mustn’t)或not have to。
