【答案】D
【详解】句意:——在新冠肺炎疫情期间,您认为我们老百姓能为祖国做些什么?——我认为我们不需要做任何事情,除了待在家里和做一些锻炼来保持健康。
考查情态动词辨析。must必须;can’t不能够;may可能;mustn’t禁止;need必须;shouldn’t不应该;can能够;needn’t不必。根据“What do you think we common people … do for our motherland during the Covid-19 breakout”可知,此处询问能做些什么;根据“I think we … do anything except staying at home and do some exercise to keep ourselves fit”可知,不需要其他的事情,只能待在家里和做锻炼,故选D。
46.(2022·江苏无锡·二模)We ________ never pay too much attention to protecting ourselves from catching the virus.
A.should B.must C.may D.can
【答案】D
【详解】句意:我们再怎么注意保护自己不被病毒感染也不为过。
考查情态动词。should应该;must必须;may可能;can会,能;can not/never pay too much attention to doing sth“无论多么注意做某事都不为过”,是固定短语,故选D。
47.(2022·江苏镇江·二模)You ________ pay too much attention to your pronunciation, as it is so important in oral test.
A.shouldn’t B.mustn’t C.can’t D.needn’t

【详解】句意:你再怎么重视你的发音也不为过,因为它在口试中是如此重要。
考查情态动词。shouldn’t不应该;mustn’t不允许;can’t不能;needn’t不必。can’t…too much“再怎么样也不为过”,固定搭配,根据“as it is so important in oral test”可知,因为口试中发音很重要,所以再怎么注意也不为过。故选C。
48.(2022·浙江温州·三模)—Is the lady waiting at the school gate your mother, Alex?
—No, it ________ be her. She has gone to Hainan on business.
A.mustn’t B.can’t C.needn’t D.shouldn’t
【答案】B
【详解】句意:——亚历克斯,在学校门口等着的那位女士是你妈妈吗? ——不,不可能是她。她因公去了海南。
考查情态动词。mustn’t绝对不能;can’t不可能;needn’t不必;shouldn’t不应该。根据“She has gone to Hainan on business.”可知,在学校门口等着的那位女士“不可能”是亚历克斯的妈妈,这里是否定的推测,用can’t be。故选B。
49.(2023·天津河东·二模)—There is someone knocking at the door. I wonder who it ________ be.
—It ________ be Peter. He phoned to tell me he would come here soon.
A.must; must B.could; must C.might; can’t D.might; mustn’t
【答案】B
【详解】句意:——有人在敲门。我想知道可能是谁。 ——一定是彼得。他打电话告诉我他很快就会来这里。
考查情态动词。此题先考虑第二个空,must一定;can’t不可能;mustn’t禁止。根据“He phoned to tell me he would come here soon.”可知,敲门的“一定”是弗兰克,填must。C/D不正确。第一个空,must必须、一定;could能、可能。根据“I wonder who it…be.”可知,这里表示推测。A不正确。故选B。
50.(23-24九年级·江苏无锡·阶段练习)If you are feeling life just ________ be any worse for you, it will be challenging to think something cheerful.
A.can’t B.mustn’t C.should D.may

考查情态动词。can’t不能;mustn’t禁止;should应该;may也许。“can’t be+比较级”表示“再没有更……的了”,结合语境,故选A。
