25、睛：can的基本用法：1. (表示能力、功能)能，会；2. (表示推测)可能，可能会；3.（表示允许，请求）可以；4.（表示客观可能性）有时会。2C【解析】考查情态动词。句意：我仍然记得我幸福的童年，那时妈妈会在周末的时候带我去迪士尼乐园。A.might可能；B.must必须；C.would将，会；D.should应该。would可以表示“过去常常”，强调过去经常发生的事情。根据语境判断此处指过去妈妈经常在周末带他去。故选C项。3C【解析】考查情态动词辨析。句意：-那边的牌子上写的是什么?-任何人不得在本地区吸烟或携带点燃的香烟、雪茄或烟斗。A. will表示现在的意志、愿望等，意为要，希望；

26、 B. may表示许可，或用于请求许可，意为可，可以；C. shall在陈述句中用于第二人称或第三人称，表示说话者的意志、命令、约定、决心、警告、威胁、预言等，意为必须，应该，要，得，给； D. must意为必须, 要,应当。 分析句意可知，词句表示任何都不准在这个区域吸烟或携带点着的香烟、雪茄或烟斗。故选C项。4D【解析】考查情态动词的用法。句意：关于英国人你可以肯定的一点是他们谈论很多的天气。A. need需要；B. must必须；C. should表示责任和义务；D. can可以；能够。根据语境，故选D。5D【解析】考查情态动词辨析。句意：尽管你能在伦敦找到便宜货，但是一般不是购物便宜的

27、地方。A. should应该；B. need需要；C. must必须；D. can能。can用在否定句和疑问句中可以表示具体的可能性，用在肯定句中表示理论上的可能性，本句中在伦敦可能能买到便宜货就是理论上的可能性，用can表示。故选D。6D【解析】考查情态动词。句意：-门怎么了?-钥匙卡在里面出不来了。A. shouldnt不应该；B. mustnt禁止；C. neednt 不需要；D. wont不会。wont表示拒绝时，其主语有时可以是“物”。故选D项。7C【解析】考查情态动词。句意：我来新学校之前本没有必要担心，因为在这里我的同学对我非常友好。neednt have done本没有必要做某

28、事，表示实际上已经做了某事。根据后一句“for my classmates here are very friendly to me.”可知，同学对我非常友好所以我本没必要但心。mightnt也许不；mustnt不允许；couldnt不可能。故选C。8D【解析】考查情态动词。句意：哈里感到很不舒服，他在昨晚的聚会上一定是喝得太多了。must have done用于肯定句，表示对过去情况的肯定猜测。可能性较大，一般有一定根据。A.could have done过去本能够做某事，而实际上未做；B.need have done过去本有必要做某事，而实际上未做；D.would have done过去本

29、想要做某事，而实际上未做。根据 last night并结合语境可知，该句是对过去有把握的推测，而非与过去事实相反的假设或结果。故选C。9C【解析】考查情态动词+have done。句意：乔治不可能走得太远。他的咖啡仍然是温的。cant have done一定不可能做了某事；must have done过去一定做了某事；might have done过去可能做了某事；neednt have done过去本不必做某事。故选C。【点睛】熟练掌握情态动词的用法，对准确理解语法填空、完形填空、阅读理解、听力理解中含有情态动词的句子是很有益处的，并且在写作中也可能会用到情态动词。因此，我们应当学好情态动词

30、，尤其要掌握好常用情态动词的用法。“情态动词+have done”的用法：情态动词无论是表达“推测和可能性”，还是表达“虚拟”这一概念，只要是表达过去已经发生的事情，一律用“情态动词+have done”这一结构；表达现在或将来发生的事情，用“情态动词+动词/系动词原形”。注意不同的情态动词和have done搭配的含义。表示推测的can have done一般用于疑问句和否定句中10D【解析】考查情态动词表推测。句意：我不能找到我的钱包了，昨天我有可能把它落到超市了，但我不确定。根据句中时间状语yesterday可知，是对过去事情的推测，故用情态动词+ have done，再根据后句but

31、Im not sure.可知，此推测为不能肯定的推测，故用情态动词could，表示“可能”。故选D。【点睛】情态动词是每年高考的热点也是难点。本题抓住两点：第一、时态。根据句中时间状语可以判断出是对过去事情的推测，故用情态动词 + have done；如果是对现在事情的推测，才用情态动词+v原形。第二、情态动词的选择。must为肯定推测，表示“一定”，could为不肯定推测，表示“可能”，这样就能选出正确答案。11D【解析】考查情态动词+have done结构。句意：对不起，妈妈，我面试又失败了。噢，那太糟糕了，你应该做好充分准备的。A.must必须；B.can可以；C.would将会；D.s

32、hould应该。这里是情态+have done的结构的虚拟语气，can+have+done”表示对过去行为的怀疑，用于疑问句，译成“可能做过吗？”；could+have+done，表示对过去事情的假设，意思是本来能够做某事而没有做；must+have+done”表示对过去事情的肯定推测，译成“一定做过某事”，该结构只用于肯定句；should+have+done意思是“本来应该做某事，而实际没做”。故选D【名师点睛】情态动词是一种本身有一定的词义，表示说话人的情绪、态度或语气的动词，但它不能单独作谓语，只能和其他动词一起构成谓语。情态动词是每年高考的热点也是难点，每年单项填空题必考一题。考点集中

33、在：情态动词表示推测的基本用法及区别，情态动词否定式的用法辨析，“情态动词+have done”的用法区别等。12D【解析】考查情态动词。句意：我的词典在哪里？我记得昨天放在这里了。你或许放错了地方。“might have +动词+ed形式”表示过去可能完成的动作。根据所提供的情景Where is my dictionary? I remember I put it here yesterday.可判断出把词典放在某个地方发生在过去，所以要用“might have +动词+ed形式”。“should have + 动词+ed形式”表示“(过去)本来应该做某事”。must意为“一定”，是肯定的推

34、测，与所提供的情景的矛盾。might put表示现在发生的事。故选D。13C【解析】考查虚拟语气。句意：真遗憾！你错过了这次观光，否则，我们本应该在一起度过一段愉快时光的。根据上文可知，是对过去事情的虚拟，是与过去事实相反的假设。其句子结构为：从句：If+主语+过去完成时+其他，主句：主语+should(would, could, might)+现在完成时+其他，故选C。14D【解析】考查虚拟倒装句。句意：如果我早知道日程安排，可能会省去我一些麻烦。根据题干中might have saved可知主句是对过去的虚拟，从句应用if I had known与主句保持一致。if虚拟条件句中含有had时

35、，可将if省去，同时将had提前构成倒装结构。故选D项。【点睛】虚拟语气重要做题原则：根据题干中主句或从句中动词形式判断所考查的动词的虚拟时间, 一般要保持一致，但要注意错综时间虚拟语气要根据各自所表示的虚拟时间做出调整。另外，当 if 条件句中含有助动词 had，should 或 were 时, 可以省略 if，而将 had, should 或 were提到句首，从而构成倒装虚拟条件句。15B【解析】考查虚拟语气。句意：真奇怪，他竟然没有主人的允许就拿走了这些书。在句型”It is important/necessary/strange/impossible/natural that.”中，

36、其中由that引导的主语从句通常用“should+动词原形”这样的虚拟语气，其中的should可以省略。故选B。点睛：本题考查虚拟语气。It is important/necessary/strange/impossible/natural that. 主语从句多数情况下用虚拟语气，表达一种要求、命令或者责备、建议或主观看法。但是如果只是表示陈述一个事实而不是强烈的感情，完全可以用一般的陈述语气。试比较：It is strange that he had made a mistake.（陈述一个事实：他犯了错误让人有点奇怪。）It is strange that he (should) hav

37、e made a mistake. （虚拟语气，说话者是在责备他本不应该犯错。）16B【解析】考查虚拟语气的省略。句意：要不是老师们的支持，该生是无法克服她自己的困难的。根据句意可知，表示与过去相反的虚拟语气，虚拟语气中，be动词统一用were；虚拟语气的省略形式主要是把if省略，同时把were/should/had提前，即Were /Should/ Had +主语.，故选B。17A【解析】考查虚拟语气。句意：在这个村里有很好的社交生活，并且我希望我再有一次机会去更多的参与。本题考查wish引导的宾语从句，表示与现在事实相反的愿望，所以从句用一般过去时。故选A。点睛：本题考查wish引导的虚拟

38、语气。由wish引起的表示愿望的虚拟语气：1用wish表示对现在的愿望时，它所引起的宾语从句中谓语动词形式为：过去式（be动词用were）。2用wish表示对将来的愿望时，它所引起的宾语从句中谓语动词形式为：would, could, might+ 动词原形。3wish用于对过去的事实表示一种不可能实现的愿望时，宾语从句中的谓语动词形式为：had+动词过去分词或could, would + have +done。分析此题需抓住前句There is a good social life in the village的时态是一般现在时，可以判断出此题wish用于表示现在不可能实现的愿望。18D【解

39、析】考查虚拟语气。句意：如果政府和科学家不共同努力，与艾滋病相关的死亡就不会从2005年的最高点下降。根据句意可知，使用虚拟语气表示与过去相反的事实，if条件句用had done，省略if，将had提前，主句用would have done表示对过去情况的虚拟，故选D。19B【解析】考查虚拟语气。句意：Jane真希望她在大学时学的是外贸而不是文学。wish后接宾语从句，从句用虚拟语气，若表示与过去相反的愿望，从句谓语用过去完成时或would / could+have +过去分词。由“when she was in college”可知，本句表与过去事实相反的假设，所以从句为过去完成时。故选B项

40、。【点睛】动词wish后接宾语从句时，从句谓语要用虚拟语气。若要表示与现在事实相反的愿望，从句谓语用一般过去时或过去进行时；若表示与过去相反的愿望，从句谓语用过去完成时或would / could+have +过去分词；若表示将来没有把握或不太可能实现的愿望，用would (could)动词原形。分析句子可知，由“when she was in college”可知，本句表与过去事实相反的假设，所以从句为过去完成时。20D【解析】考查虚拟语气中的情态动词。句意：真遗憾啊！考虑到他的能力和经验，他也许可以做得更好。can have done较少使用此结构，表示对过去行为的怀疑；用于疑问句时意为“

41、难道真的做了吗”，表示怀疑；need have done需要做某事，实际上却未做（表示虚拟语气）；must have done一定做了某事（表示对过去发生的事情的肯定推测）；might have done表示对发生过的事情的推测，意思是“可能已经”或“也许已经”，用于肯定句中。故D正确。【点睛】本题是高考必考考点，一定要牢记句型意思。must have done过去肯定做了某事。should have done本应该做而实际未做。cant have done过去不可能做了某事；shouldnt have done 本不应该做而实际做了。need have done本有必要做某事而没做；need

42、nt have done本没有必要做某事；注意没有mustnt have done的形式。21D【解析】考查虚拟语气。句意：如果他们知道接下来发生什么，他们会再想一想。本句是一个倒装句，可还原为：if they had known what was coming next, they might have had second thought。根据had known提示，可知是与过去事实相反，因此虚拟语气主句中应该用would/might have done，故选D。拓展练1D【解析】考查虚拟语气。句意：玛丽对这次聚会的描述是如此生动，以至于我觉得我好像去过那里一样。根据句意及句中felt可知

43、，此处描述的是与过去事实相反的情况，应使用过去完成时。故D选项正确。2A【解析】考查虚拟语气。句意：如果这个新的安全系统被投入使用过的话，这个事故就不会发生了。根据主句确定是对过去情况的虚拟，所以从句谓语用had done形式，此外根据句意可知是被动，用被动语态，故A项是正确的。3D【解析】考查虚拟语气。句意：工人们没有被更好的组织起来，否则他们用一半的时间就能完成任务。根据上句the workers were not better organized可知，这是对过去事情的虚拟。表示与过去事实相反的假设，其句子结构为：从句：If+主语+过去完成时+其他，主句：主语+should(would,

44、could, might)+现在完成时+其他，故选D。4D【解析】考查虚拟语气。句意：我当时系着安全带。如果我没有系安全带，我就会受伤了。使用虚拟语气，根据if条件句用的had done可知，主句用would have done表示对过去情况的虚拟，而且I和injure是被动关系。故选D。5A【解析】考查虚拟语气。句意：如果不是因为前几天他的邀请，我现在就不会在这里了。根据下文“我现在不应该在这里”可判断，考查错综时间虚拟条件句，根据从句中的the other day可知，从句表示与过去相反的虚拟语气，使用过去完成时，故A项正确。【点睛】有时条件从句和主句所表示的动作在时间上可以不一致（例如一

45、个与过去事实相反，另一个与现在事实相反），这种虚拟条件句就称为错综时间虚拟条件句。在这种条件句中，动词的形式要根据具体情况进行调整。如： 1.She would never have behaved like that if she had some common sense.如果她有一些常识的话，她就决不会那样做了。 2.If I had a bike (now), I would have lent it to you yesterday.假如我有自行车，昨天就借给你了。6A【解析】考查情态动词。句意：太吵了，以致我们不能够听到我们在说什么？A的意思是不能，B的意思是不应该，C的意思是禁止

46、，D的意思是不需要。该题用到了一个so +形容词+ that的句式，此处句式表示“如此以至于”，因此推断此处表示“不能够”。故选A。7C【解析】考查情态动词的基本用法。句意：我已经点了一些披萨，所以我们回家累了就不用担心做饭了。A. cant表示“无能力”；B. dare not表示“无勇气”；C. neednt意为“无必要”；D. may not表示“推断”。 因为买了比萨饼，无必要担心回家后疲劳还要做饭。故选择C项。8D【解析】考查虚拟语气。句意：我们在那个小村庄里迷了路，否则昨天我们会参观更多的名胜古迹。由语境及otherwise可知，逗号后的部分是一个含蓄条件句，由lost可知，此处表

47、示与过去事实相反的情况，故用would/could/should/might+have done结构。故选D。9C【解析】考查虚拟语气。句意：如果我没有面对那么多的障碍，我现在就不会在这里。分析句子成分可知，此处是错综时间虚拟语气，根据空后where I am可知，此处是与现在事实相反的假设，主句谓语动词应使用would/could/might/should+do。故选C。10B【解析】考查情态动词。句意:吉姆说我们可以住在他的房子里，只要我们保持它干净整洁。A. must必须；B. can能，可以；C. need需要；D. should应该。根据后面的“as long as we leave

48、 it clean and tidy”可知，Jim许可我们待在他的房子里，即:我们”能，可以”待在他的房子里。故选B。11D【解析】考查情态动词+ have done。句意：你本不应该因为他表现不好而责骂他。毕竟，他已经尽力了。根据前后句关系可知此处表示“本不该”是 shouldnt have done指做了本不该做的事，must have done表示对过去发生的事情的肯定性推测；should have done表示应当做某事而实际上未做；mustnt不和have done连用。故选D。【点睛】must have done表示对过去事情的肯定推测，指“一定做过某事”，该结构只用于肯定句：1.

49、 It must have rained last night, for the ground is wet.昨晚一定下雨了，因为地面还是湿的。2. You must have been mad to speak to the servant.你和仆人说话，一定是发疯了。should have done意思是“本来应该做某事，而实际没做。” shouldnt have done表示本来不应该做某事,而实际做了。含有指责对方或自责的含意.1. Tom, you are too lazy. The work should have been finished yesterday.汤姆,你太懒惰了,

50、这项工作本来应该昨天就做完的。 2. Look, Tom is crying. I shouldnt have been so harsh on him.看，汤姆哭了，我本来不应该对他如此严厉。本题是 shouldnt have done的用法。模拟练1A【解析】考查情态动词+完成式。句意：这个女孩成为了第一个登上著名国际舞台的中国歌手。她一定花了不少功夫。固定结构：must have done意思是“一定是做某事了”，表示对过去事情有把握的肯定推测。结合句意，故选A。2B【解析】考查情态动词。句意：有一台计算机来储存照片真是太棒了。不要过度依赖它。它有时候也会出故障，你最好做一个备份。分析句

51、子可知，计算机出故障这是可能的事情，表示客观可能性用can。故选B项。3C【解析】考查情态动词+have done。句意：春节期间我本来想走亲访友，但是因为COVID-19疫情的爆发，我只好呆在家里。would have done是一个固定虚拟语气的用法。表示对过去事情的假设，意为“本来想做、要做但没做”。根据句意可知是对过去的假设，应用would have done。故选C项。4D【解析】考查推测句。句意：他可能告诉过你他是一个合格的代理人，但事实刚好相反。A. must tell肯定告诉；B. could tell可能告诉；C. should have told本应该告诉；D. might

52、 have told可能告诉过。根据句意和宾语从句的was判断，此处是对过去情况不太确定的推测，应用might have done“可能做过某事”，故选D项。5B【解析】考查情态动词用法。句意：友谊是世界上最伟大的事情之一，但友谊有时会很难。A. would将会，表示意志、愿望和决心；B. can可能，能够；C. should应该，可以表示说话人的情感；D. must必须，一定要。结合后文be 可知表示偶尔的可能性，意为“有时会”，其后通常接“be (get, seem, become等)+形容词”应用can。故选B。6D【解析】考查情态动词。句意：我真的不喜欢James。你为什么邀请他？别担

53、心，他可能不会来。他说了他不确定他的计划是什么。A. must not禁止；B. need not不需要；不必C. would not不会；D. might not可能不。根据下文“He said he wasnt certain what his plans are.”可知，他可能不来。故选D。7B【解析】考查情态动词。句意：你为什么这么关心他？你真应该看看他第一次出现时的样子，真是太伤感了。should have done（过去本应该做某事却未做），表达一种责备或内疚的语气；由语境可知，此处指说话的一方指责另一方，过去本应该做却未做的事，即“真应该看看他第一次出现时的样子”。故选B项。8D

54、【解析】考查情态动词+have done。句意：你本不应该因为他表现不好而责骂他。毕竟，他已经尽力了。根据前后句关系可知此处表示“本不该”是shouldnt have done，指做了本不该做的事，故选D。【点睛】must have done表示对过去事情的肯定推测，指“一定做过某事”，该结构只用于肯定句。1. It must have rained last night, for the ground is wet. 昨晚一定下雨了，因为地面还是湿的。2. You must have been mad to speak to the servant. 你和仆人说话，一定是发疯了。should have done意思是“本来应该做某事，而实际没做。” shouldnt have done表示本来不应该做某事，而实际做了。含有指责对方或自责的含意。1. Tom, you are too lazy.
