他不戴眼镜。
考查情态动词表推测。
否定推测用can’t/couldn’t;肯定推测用must, may, might, must意思是“一定、准是”,语气较肯定,较有把握。
may, might表示推测“可能性”时,意思是“可能”、“也许”,语气没有 must肯定。
mustn't的意思禁止做某事。
根据下文He doesn't wear glasses.(他不戴眼镜。
)可以推测这副眼镜不是丹尼的;结合句意和语境可知选A。
2.A解析:A【解析】【详解】句意:请你说大点声好吗?我不能很好地听到你说的话。
考查情态动词辨析。
can't不能,表示不能够;mustn't不许,表禁止;shouldn’t不应该,表劝诫;needn’t无需,表示没必要。
本句表示“不能够”,根据句意语境,可知BCD三项意思都与句意不合,故选A。
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:——你认为网上购物安全么?——我觉得是的。
淘宝上,消费者可以无理由退货,但是他们要承担运费。
考查情态动词辨析。
A. can’t; can不能,能;B. must; must必须,必须;C. can; have to可以,不得不;D. mustn’t; can禁止,能。
根据句意表示的是顾客能退货,是可以,第一空用can;但是不得不承担运费,非主观情愿用have to。
故选C。
5.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。
6.C解析:C【解析】【详解】句意:--这栋楼是多么好呀!它用来做什么的?--它可能是一个旅馆,我不确定。
A. must be一定是;B. have to be 不得不;C. may be也许是;D. can be可能是。
根据But I'm not sure可知,这里表示的可能性小;can 表示推测的是用于否定句或疑问句,故选C。
7.A解析:A【解析】【详解】句意:牛奶味道不好。
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。
8.B解析:B【解析】【分析】【详解】句意:我看不到黑板了。
我需要戴眼镜。
考查情态动词。
根据后句“I need to have my glasses.”可知看不到黑板,所以需要戴眼镜。
can能够;can’t不能够;must必须;mustn’t禁止。
根据句意可知,此处表示“不能够”,故选B。
9.D解析:D【解析】【分析】【详解】句意:——看!史密斯太太正站在教学楼的前面。
——不可能是他。
她去埃及度假了。
考查情态动词表示推测。
must be一定是;mustn’t be禁止是;can be可能是;can’t be不可能是。
根据She has gone to Egypt for her holiday.可知她去了埃及,不可能站在教学楼前,故选D。
