18、. shouldnt D. mustnt情态动词表推测用法总结及专项练习1.can / could用于表推测的用法(1) 从使用句型上看，can 通常只用于否定句或疑问句，一般不用于肯定句，而could 可用于肯定句、否定句和疑问句。两者没有时间上的差别，只是could 比 can 更委婉，更不确定。如：It cant couldnt be true. 那不可能是真的。What can could they be doing? 他们会在干什么呢?We could go there this summer. 今年夏天我们可能要去那儿。注：can 有时也用于肯定句中表示推测，主要用于表示理论上的可

21、e died laughing. 我差点儿笑死了。2. may / might用于表推测的用法表示推测，两者都可用，只是 might 比 may 语气更不确定，表示的可能性更小。(1) 在句型使用方面：两者均可用于肯定句和否定句，但用于疑问句时，may通常不用于句首，但可用于疑问句的句中（如特殊疑问句等），而might尽管可以用于疑问句的句首，但不算普通，通常会改用其他句式（如用could等）。如：He may might know the answer. 他可能知道答案。He may might not believe you. 他可能不会相信你。And who may might she

22、be? 那么她会是哪一位呢？(2) 从时间关系看，对现在或将来情况作推测，后接动词原形；对正在进行的情况作推测，后接 be doing 结构；对过去情况作推测，后接动词完成式。如：He may might tell his wife. 他也许会告诉他妻子。He may might be writing a letter. 他可能在写信。She may might have read it in the papers. 她可能在报上已读到过此事。(3)“might+完成式”除表示对过去的推测外，还有以下重要用法： 表示过去某事可能发生而实际上却并没发生。如：It was really very

25、应该告诉我。He should have arrived by now. 此时他本该到了。Look at the time!

Naturally, after I told

27、 her what to do, my daughter _ go and do the opposite! A. may B. can C. must D. should (2003年普通高等学校春季招生统一招生考试英语试题（安徽卷）)【分析】Can,may,must都可用来表示”推测”，但侧重点各有不同：May常用来指”事实上的可能性”，而can则表示一种”理论上的可能性”例如：The railways may be improved.=It is possible that the railways will be improved.=Perhaps/Maybe/Possibly the

28、 railways will be improved.铁路可能会得到改进。（意味着已有具体的改进计划或方案。）The railways can be improved.=It is possible for the railways to be improved.铁路可以得到改进。（意思是铁路还不完善，尚有问题存在。）理论上的可能性(can)比事实上的可能性(may)更弱。在一般的陈述句，can与sometimes几乎相同，表示一种偶然的可能性。比如：Even expert drivers can make mistakes.甚至是很熟练的驾驶员也可能会犯错。=Even expert driv

29、ers sometimes make mistakes.=It is possible for the expert drivers to make mistakes.因此，如果讲的是一种特殊情况，不是一般情况，就用may,试比较：Mr Reed looks pale.He may be ill.Mr Reed is in poor health.He can be ill at any time.Must指逻辑必然,作“想必”、“准是”、“一定”解，用来表示我们对某事有把握的推论或揣测。（考虑到迹象如此，再无别的结论=It seems certain that.）:They must be

30、very tired now, for they have been working the whole morning.他们现在一定是非常累了，因为他们整个上午都在工作。析：填C.must。意思是”不出所料，当我告诉女儿要做的事时，她准会去做相反的事。”【考例】1、Mary _ be in Paris.I saw her in town only a few minutes ago.(NMET1994) A.mustnt B.shouldnt C.cant D.may not 2、.-Is John coming by train? (NMET 2002 Tianjing ) -He sho

31、uld,but he _ not.He likes driving his car.Amust B.can C.need D.may【分析】May用于否定时，not不是否定may，而是否定句中的动词，这一点与can不同，试比较：He may not know the truth.他可能不知道事情的真相。（=It is possible that he didnt know the truth.）He cannot know the truth.他不可能知道事情的真相。must表示推测的这种用法通常用在肯定句中，在疑问句中常用can(可能)，在否定句中常用cant(不可能，不会是)，而不用mus

32、tnt。例如：- Somebody is knocking at the door. Who can it be ? It must be Wang Hong.- No, It cant be Wang Hong, because she left for Shanghai this morning.-有人在敲门。会是谁呢？一定是王红。-不，不会是王红，因为她今天早晨就动身去上海了。因而You must be joking.在意义上相当于You cant be serious.析：1、填C。意思是”玛丽不可能在巴黎。几分钟前我还看见她在镇上。2、填D。意思是”-约翰会坐火车来吗？-应该会，但他

33、可能不会。他喜欢开车。”【考例】1.-I heard they went skiing in the mountains last winter. (NMET 2002Beijing ) -It _ true because there was little snow there. A.may not be B.wont be C.couldnt be D.mustnt be 【分析】Could,might表示过去的可能性。I thought it might be true.我本认为那是真的。He could be very unreasonable.他有时可能毫不讲理。析：填C。它是对去年

34、冬天所发生的事进行评价。【考例】1.-Are you coming to Jeffs party? (NMET 2000) -Im not sure.I_go to the concert instead. A.must B.would C.should D.might 2.-Look!The clouds are gathering. -Yes.Im afraid it _ be pouring down soon. A,can B,must C,should D,might【分析】could和might表示现在的情况时，更带有不肯定性和慎重味道，构成礼貌或婉转说法，包含或许的意思：A:I

35、wonder where Tom is. B:He may/might/could be in the library.(Perhaps he is in the library.)因此在wonder, fear,be afraid等后接的从句中,通常用may/might/could,表达一种探询的观点：I was afraid you might be out of sorts.我怕你可能心情不痛快。假设性的可能和试探性的可能，也用could和might：Our team might still win the race.(可以意译为：It is possible,though unlike

36、ly,that )析：1、2均填D.might【考例】Mr. Bush is on time for everything. How _ it be that he was late for the opening ceremony? Acan Bshould Cmay Dmust(2001年上海普通高校春季招生考试试卷)【分析】表示推测的may通常不用于一般疑问句，而要用can代替。Can用于一般疑问句时，还可表示惊讶或怀疑，意思是”（到底）可能有这样的事吗？”，比如：“There is the doorbell.”Who can it be at this time of day?”有人按

37、门铃。”这个时候到底会是谁呢？”Must也偶尔用于疑问句：Must there be some good reason for the delay?这个问句设想的是一个肯定的回答，可以解释为”Does there have to be some good reason?”may可用于特殊疑问句或wh-从句，意思是”（到底）是”、”不知是否”：I wonder what it may mean.我不知道这究竟是什么意思。How old may his father be?他父亲到底有多大年纪？（比How old is his father?委婉的说法。）析：填1、A.can.（布什先生做什么事都

38、很按时。他怎么可能会在开幕式上迟到呢？）【考例】1. Sorry Im late. I _ have turned off the alarm clock and gone back to sleep again.( 2000年普通高等学校春季招生考试 (北京、安徽卷) A. might B. should C. can D. will 2.There were already five people in the car but they managed to take me as well. It_a comfortable journey. (NMET95) A.cant beB.sho

39、uldnt be C.mustnt have beenD.couldnt have been【分析】“情态动词have + -ed分词”结构可以表示对已发生的事情进行推测, 就表示的可能性程度而言，must最大，could其次，may更次之，might最小。must + have + -ed分词: 用于肯定句, 表示推测过去某事“肯定,一定，准是”发生了。 其否定形式为：cant / couldnt have v-ed, 表示过去不可能发生某事。 may(might) + have + -ed 分词: 用于肯定句和其他否定句, 表示对已发生事情的不肯定的推测, 意为“可能, 大概”, 其中mi

40、ght较may语气更弱, 把握更小。Can/could用于否定或疑问句中,表示对过去发生的事件的“怀疑或不肯定”。could 比can更表示说话人语气的不肯定。例如： I mailed that letter a week ago. He must have received it.我一周前就发出了那封信, 想必他一定收到了。I cant find my keys. I may / might have left them at the school yesterday.Jack cant have arrived yet,otherwise he would have telephoned

41、me.（上海1997）It couldnt have been Mr. Smith. He has gone to China.不太可能是史密斯先生。他已去了中国。另外，注意may不可用于疑问句，它的这种功能已为can所取代。例如Can they have missed the bus?的答句是：Yes,they may have done.而不是Yes,they can have done.这一点要注意。Must偶尔也能用于否定句：His absence must not have been noticed.此句和His absence cant have been noticed.的意思是

42、一样的。许多评论者认为这类句子是不可能成立的，但它们正在为越我来越多的人所接受和使用，在美国英语中尤其如此。对正在发生的事情进行推测，则采用”情态动词+be+现在分词”结构，其中情态动词的区别与上相同。析：答案A、D。can通常不用于肯定句表猜测；”should+have+-ed分词”表示”过去本来应该做”，但实际上没有做，意思是”本该.”，带有责备口气:I was really anxious about you.You shouldnt have left without a word. (NMET2001) ；”will+have+-ed分词”只是将来完成时的一种形式。【考例】1.Its

43、 nearly seven oclock. Jack _be here at any moment. (NMET95) A.must B.need C.shouldD.can 【分析】should(ought to)表示很可能、预期的意思，指一种尝试性推论，可认为是must的语气较弱的对应词，意思是”应该会、一定。吧”。试比较：Our guests must be home by now.(I am certain)我们的客人现在一定到家了。（根据他们动身的时间、路程远近、速度等具体条件，我能断定/肯定他们现在已经到家了。）Our guests should(ought to) be home

44、 by now.(They probably are,but Im not certain.)我们的客人现在该到家了。（含义是我想他们很可能到家了，但我不能肯定”）与must不同还在于它常常表示将来：-When can I come for the photos?I need them tomorrow afternoon.-They_be ready by 12:00. (NMET1998) A.can B.should C.might D.need表示不太可能可用shouldnt(oughtnt to):There shouldnt(oughtnt to) be any difficulties.不该有任何困难。析：填C。意思是”将近七点了。杰克很可能随时会到
