18、oney again?a. needntb. cantc. shouldntd. 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那true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

19、：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能性 (即从理论上看是可能的，但实际未必会发生 )，或表示 “有时 ” 之意。如：even experienced teachers can make mistakes.即使是有经验的教师也可能出错。she can be very unpleasant.她有时很令人讨厌。(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 could have gone home.他可能已经回家了。he can t couldnt have un

20、derstood他不.可能理解了。3why does he know this? can could someone have told him about it? 他怎么知道 ? 会是哪个人告诉他了吗 ?(3) “could+完成式 ”除表示对过去的推测外，还有以下重要用法： 表示过去没有实现的可能性，常译为“本来可以 ”。如：i could have lent you the money why didn t you ask me? 我本来可以借这笔钱给你的。你为什么不向我提出 ? 用来委婉地责备某人过去应该做某事而没有去做，常译为 “本来应该 ”。如：you could have hel

21、ped him.你本来应该帮助他的。 表示 “差点儿就要 ”。如：i could have 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 mi

22、ght not believe you.他可能不会相信你。and who may might she 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，

23、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：4it was really very dangerous. i might have killed myself.那真的是太危险了，我差点没命了。a lot of men died who might have been saved 很多人本来可以获救的却死了。 表示委婉的批评或责备。如：you might have made greater progress. 你的进步本来可更大一些的。you might at least have answered my letter. 你至少可以回我一封信嘛。3. must 表示推测的用法

24、must 表示很有把握的推测，其意为 “一定会 ”“肯定会 ”，只用于肯定句，一般不用于否定句或疑问句。 表示对现在或未来的情况作推测，后接动词原形；表示对过去情况的推测，接动词完成式。如：i must be the happiest woman on earth! 我一定是世界上最幸福的女人了。no, he must be lying.不，他一定在撒谎he must have mistaken my meaning.他一定误会了我的意思。4. should have done的用法should have done 只用于谈论过去情况，主要有两个用法：一是用于推测过去已经发生的情况， 二是用于

25、指本该发生而实际上未发生的情况。如：you should have told me so before.你早就应该告诉我。he should have arrived by now.此时他本该到了。look at the time! we should have been at the theatre ten minutes ago. 瞧都什么时候了 ! 十分钟前我们就该到戏院了。5. need have done的用法need have done 结构主要用于否定句或疑问句， 一般不用于肯定句。用于否定句时，表示本来不必做某事，但实际上却做了；用于疑问句时，用于询问某一过去动作的必要性。如：

26、you needn t have hurried. 你当时实在不必那么匆忙。5she needn t have come in person aletter would have been enough. 她本不必亲自来 写封信来就足够了。need you have paid so much?你当时真须要付那么多钱吗?need they have sold the farm?他们那时非得把农场卖掉不可吗?历届 nmet 中表推测的情态动词的用法情态动词是中学英语学习中的一个重点和难点， 也是高考的重点考察内容之一。其中表示推测用法的情态动词在近几年的高考中更是屡见不鲜。现结合近几年的高考题目，

27、 对表推测的情态动词的用法作一归纳，希望对各位考生会有所帮助：【考例】 1. naturally,afteri toldher what todo, mydaughter_ 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 pos

28、sible that the railways will be improved.=perhaps/maybe/possibly the 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

29、。比如：even expertdriverscan make mistakes. 甚至是很熟练的驾驶员也可能会犯错。=even expert drivers 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

30、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 seems6certain that）.:they must be very tired now, for they have been working the whole morning.他 在一定是非常累了，因 他 整个上午都在工作。析：填 c.must 。意思是 ”不出所料，当我告 女儿要做的事 ，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.mustn

31、t b.shouldn t c.can td.may not 2、.-is john coming by train? (nmet 2002 tianjing )-he should,but he _ not.he likes driving his car.a must b.can c.need d.may【分析】 may 用于否定 ， not 不是否定 may ，而是否定句中的 ， 一点与 can 不同， 比 ：he maynotknowthe truth. 他可能不知道事情的真相。（=it ispossible that he didnt know the truth）.he canno

32、t know the truth.他不可能知道事情的真相。must表示推 的 种用法通常用在肯定句中，在疑 句中常用can( 可能 )，在否定句中常用cant(不可能，不会是 )，而不用 mustnt。例如：- somebody is knocking at the door. who can it be ? it must be wang hong.- no, it can bet wang hong, because she left for shanghai this morning.-有人在敲 。会是 呢？一定是王 。-不，不会是王 ，因 她今天早晨就 身去上海了。因而 you mus

33、t be joking. 在意 上相当于 you cant be serious. 析：1、填 c。意思是 ” 不可能在巴黎。几分 前我 看 她在 上。 2、填 d。意思是 ”- 翰会坐火 来 ？ - 会，但他可能不会。他喜 开 。 ”【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 bed.mustnt be【分析】 co

34、uld,might表示 去的可能性。i thought it might be true.我本 那是真的。he could be very unreasonable.他有 可能毫不 理。析：填 c。它是 去年冬天所 生的事 行 价。【考例】 1.- are you coming to jeffs party? (nmet 2000)7-i m 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 po

35、uring down soon.a,can b,must c,should d,might【分析】 could 和 might 表示 在的情况 ，更 有不肯定性和慎重味道，构成礼貌或婉 法，包含或 的意思：a:i wonderwhere tomis.b:hemay/might/couldbe in thelibrary.(perhaps he is in the library.)因 此 在 wonder,fear,beafraid等 后 接 的 从 句 中 , 通 常 用may/might/could,表达一种探 的 点：i was afraid you might be out of so

36、rts.我怕你可能心情不痛快。假 性的可能和 探性的可能，也用could和 might ：our teammightstillwin therace.( 可 以 意 译 为 ： it ispossible,though unlikely,that)析： 1、 2 均填 d.might【考例】 mr. bush is on time for everything. how _ itbe that hewaslate for the openingceremony?a canbshouldcmaydmust(2001 年上海普通高校春季招生考 卷 )【分析】表示推 的 may 通常不用于一般疑 句

37、， 而要用 can 代替。can 用于一般疑 句 ， 可表示惊 或 疑，意思是”（到底）可能有 的事 ？ ”，比如：“there is the doorbell.” who can it be at this time of day? 有”人按 。 ” 个 候到底会是 呢？ ”must 也偶 用于疑 句： must there be some goodreason forthe delay? 个 句 想的是一个肯定的回答，可以解 ”doesthere have to be some good reason ?”may 可用于特殊疑 句或wh- 从句，意思是 ”（到底）是 ”、”不知是否 ”：i

38、 wonder what it may mean.我不知道 究竟是什么意思。how old may his father be?他父 到底有多大年 ？ （比 how oldis his father?委婉的 法。）析：填 1、a.can. （布什先生做什么事都很按 。他怎么可能会在开幕式上 到呢？）【考例】 1. sorry im late. i _ have turned off the alarmclock and gone back to sleep again.( 2000年普通高等学校春季招生考 (北京、安徽卷 )a. mightb.shouldc. can8d. will2. th

39、ere were alreadyfive peoplein the car but theymanaged to take me as well.it_a comfortable journey. (nmet95)a.cantbeb.shouldntbec.mustnthavebeend.couldnt have been【分析】 “情 have + -ed分 ” 构可以表示 已 生的事情 行推 , 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 : 用于肯定句 , 表示推 去某事 “肯定 ,一定，准是 ” 生

40、了。其否定形式 ： cant / couldnt have-ed,v 表示 去不可能 生某事。may(might) + have + -ed分 : 用于肯定句和其他否定句 , 表示 已 生事情的不肯定的推 , 意 “可能 ,大概 ”, 其中 might 较 may 气更弱 , 把握更小。can/could用于否定或疑 句中 ,表示 去 生的事件的“ 疑或不肯定 ”。could比can 更表示 人 气的不肯定。例如：i mailed that letter a week ago. he must have received it.我一周前就 出了那封信 , 想必他一定收到了。i can t fi

41、nd my keys. i may / might have left them at theschoolyesterday.jack cant have arrivedyet,otherwisehewouldhavetelephoned 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 句，它的 种功能已 can 所取代。例如 can they have missed the bus? 的答句是： yes,theymayhave done.

42、而不是 yes,they can have done. 一点要注意。must 偶 也能用于否定句： his absence must nothavebeennoticed. 此句和 his absence cant have been noticed. 的意思是一 的。 多 者 句子是不可能成立的，但它 正在 越我来越多的人所接受和使用，在美国英 中尤其如此。 正在 生的事情 行推 ， 采用 ”情 +be+ 在分 ” 构，其中情 的区 与上相同。析：答案 a、d。can 通常不用于肯定句表猜 ； ”should+have+ -ed分 ”表示 ” 去本来 做 ”，但 上没有做，意思是”本该 .

43、”， 有 口气:i was really anxiousabout you.youshouldn thaveleftwithoutaword.(nmet2001)；”will+have+ -ed 分 ”只是将来完成 的一种形式。【考例】 1.itsnearlyseven oclock.jack _be hereat any9moment. (nmet95)a.mustb.needc.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

44、 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 homeby now.( they probablyare,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：-whencan i comeforthe photos?ineedthemtomorrowafternoon.-they_be readyby12:0

45、0. (nmet1998)a.canb.shouldc.might d.need表示不太可能可用shouldn t(oughtn t to):there shouldn t(oughtn 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。”另外，在近几年的 nmet中，对情态动词及其它语法项目的考查均放到一定的语境中进行，要求考生利用所学英语各项基础知识进行初步的语言运用，而不再是单纯的语法知识题和短语题。这类试题往往通过题干的其他部分或附加句子提供某个信息，然后让考生根据这个信息进行合理推理，产生新的想法和认识。因此，在做

46、这类题时，除要熟悉所考查的语法规则外， 还要认真分析句子的结构，注意抓住关键词， 分析上下文的逻辑关系。不能单凭语法规则做题。巩固练习1.michael _ be apoliceman, for hes much too short.a. needtb. cantc. shouldd .may2.johnny,you _ play with the knife. you _hurt youself. a.wont,cant b.mustnt,may c.shouldnt,must d.cantt,shouldnt 3.peter _ come with us tonight,but taken
