A. didn’t steal; would be released
B. didn’t steal; released
C. hadn’t stolen; is released
D. hadn’t stolen; be released
【答案】D
【解析】句意：老人坚持说他没有偷钱，并且坚持要求被释放。本题考查 insist后接宾语从句的用法；
insist表示"坚持要求"时从句中的动词用"should+do"，should可以省略；但是insist表示"坚持说，坚持
认为"时，宾语从句该使用什么时态就用什么时态；根据句意，本题第一句是“他坚持认为”的意思，
并且主句动词insist是过去时，从句的动作“偷”是在坚持认为前发生，是过去的过去，从句应该用
过去完成时，所以排除A和B；第二部分表示"坚持要求被释放"，所以从句中的动词用"（should）
+do"。故选D。

A. dare not B. dares not C. dares not to D. not dare
【答案】A
【解析】句意：他不敢穿过这片树林。dare用作实义动词时，后接动词不定式，不定式可带to也可不
带to，且dare有人称和数以及时态的变化，在dare前加助动词加not，构成否定形式，故B、C、D项
不正确；dare用作情态动词时，后接动词原形，在dare后加not，构成否定式。故选A。
73. (2021·澳门特别行政区·单元测试)Looking at my determined face, the boy ______ pick up the fight.
A. dares not B. dare not C. doesn't dare D. dares not to
【答案】B
【解析】考查情态动词。句意：看着我坚定的脸，那个男孩不敢挑起争端。dare做情态动词时，否定
式是“dare not”，dare没有人称和数的变化，故A、D项错误；当dare做实义动词时，有时态和人称
的变化，用do, does或did来构成否定句；根据语境可知，此处讲述过去发生的事情用过去时，故用didn't dare to do的结构，故C项错误。B选项中dare用作情态动词，结构正确，故选B。
74. (2021·澳门特别行政区·单元测试)—______ touch a snake?

C. Dares she; doesn't dare D. Dares she; dare not to

doesn't dare to。根据分析，故选A。

故选B。

—She ______ them away. They must be somewhere.
A. can; mustn't have thrown B. must; needn't have thrown
C. could; couldn't have thrown D. should; might not have thrown
【答案】C
【解析】句意：——玛丽把空瓶子放在哪里呢？——她不可能扔了的，一定是在什么地方。根据情态动词的用法可知，can用来表示推测的时候，can用于疑问问和否定句。第一空是用于疑问句里，所以
用can；根据答语They must be somewhere.可知，Mary没有扔掉那个瓶子。所以第二个空格上的词是
用于否定句的，短语couldn't have done sth.表示过去不可能做了某事，故选C。
78. (2021·澳门特别行政区·单元测试)Mike _____ his car ,for he came to work by bus this morning .
A. can′t find B. mustn′t have found
C. couldn′t have found D. should have found

【解析】句意：迈克不可能发现他的车，因为今天早上他是做公共汽车上的班。couldn't have done是

际）没有做。故选C。

C. should have been laid off D. might have been laid off
【答案】D
【解析】考查情态动词。句意：——丹尼尔看起来很沮丧，怎么了？——我不知道。我想他可能被研
究所解雇了。should have done表示本应该做某事。情态动词might+have done表示对过去事情的推测。
结合句意可知，此处表示对过去发生的事情的可能性的推测，此处是被动语态，因此要用 might have
been laid off。故选D。
80. (2019·天津市市辖区·月考试卷)It is really a pleasant surprise! I had thought I in the final exam， but
it turned out that I ranked third in my class.
A. should have failed B. couldn't have failed
C. might have failed D. needn't have failed
【答案】C
【解析】句意：真是个惊喜！我原以为期末考试会不及格，结果我在班上名列第三。根据句意和结构
可知这里使用might have done意为"过去可能做了什么，时间没有"，should have done过去本应该做
某事而没有；couldn't have done过去不可能做某事；needn't have done过去本不必做而做了，故选C。
81. (2019·江苏省镇江市·月考试卷)—How do you find the club?
—I ____ it. Everyone is saying its management is going from bad to worse.
A. couldn't have joined B. might have joined
C. would rather not have joined D. would like to have joined
【答案】C
【解析】考查虚拟语气。句意：——你觉得这个俱乐部怎么样? ——我要是没参加就好了。每个人都
说它的管理越来越糟。A.couldn't have joined不可能参加过；B.might have joined可能参加过；C.would
rather not have joined宁愿没有参加过；D.would like to have joined本想要参加。would rather（not）
have done表示“宁愿做过某事但事实没做”或“宁愿没做过某事但事实却做了”，表示事实与愿望
相反。根据Everyone is saying its management is going from bad to worse 可知，第二个说话人后悔参加
了那个俱乐部，因此空格处意为“宁愿没有参加过”符合语境，故选C。

A. may have been taken away B. may leave
C. may take away D. must have taken away
【答案】A
【解析】考查情态动词和被动语态。句意：我在房间里找不到录音机。它可能被人拿走了。根据句意
可知，it和take away之间是被动关系，要用被动语态，故排除BCD。且根据I can't find the recorder in
the room. 可知，我在房间里找不到录音机，所以推测它可能被人拿走了。may have done推测过去时
间里可能发生的事情。故选A。
83. (2019·天津市市辖区·单元测试) Someone ______ the tap on, for the water was running over and
flooding the bathroom.
A. could leave B. must have left
C. might leave D. should have left
【答案】B
【解析】句意：一定是有人开着水龙头，因为水溢出来了，冲进了浴室。由后文谓语动词可知，此处
表示对过去发生的情况的一种推测，所以此处需用情态动词+have done，所以选项A和C错误；由后文句意可知，此处表示过去一定做了某事，所以空处需用must have left；should have left表示本应该
做某事，但实际未做，不符合题意。故选B。
84. (2021·澳门特别行政区·单元测试)—Is this your wallet? We found it in the restroom.

C. must have been sleeping D. must have slept
【答案】C
【解析】句意：——昨晚你为什么不接电话？——你打电话的时候我一定是在睡觉。由句中的when
you called可知，主句表示对过去的推测，需用情态动词+have done；must用于肯定句推测。且此处表
示当时正在睡觉。综上可知，需用must have been doing的形式。故选C。87. —I was lucky to win a gold medal in the 800-metre race.

A. must go B. should go
C. must have gone D. should have gone
【答案】C
【解析】考查情态动词+have done的形式。句意：——我很幸运在800米赛跑中获得了一枚金牌。
——你一定受过艰苦的训练。A.must go一定；B.should go应该；C.must have gone对过去发生的事情
的肯定推测；D.should have gone本应该做某事，其实没做。根据句意，可知一定是过去受过艰苦的训
练才能获得金牌，故该句是对过去发生的事情的肯定推测，故选C。

测”，表示“本应该做却没有做”使用should have done。故选C。

事；B.mustn't have gone 本不准去；C.shouldn't have gone本不应该去却去了；D.wouldn't have gone本

【答案】C
【解析】考查情态动词。句意：——玛丽的文章写完了吗？——没有，它本应该在下课之前完成的。
it和finish之间是被动关系，所以排除BD项；由从句的谓语动词was可知，事情发生在过去，所以此
处表示“过去本应该做了某事（但没做成）”，即ought to/should have done，结合被动语态，所以只
有C项符合。故选C。

符合语境；B.bought 为一般过去时，是真实语气；I bought．表示"我买了"，与上文矛盾，排除；
C.would like to 想要，表示现在或将来的愿望，不符合语境，但是可以用would like to have（本想要）；
