  2) 表示请求和允许。 KEJ易文君-文库范文网

  例如:-----can i go now? ---yes, you can. / no, you can’t. 此时可与may互换。在疑问句中还可用could, might代替,但could, might 并不表示过去式,只是语气更委婉。它们不能用于肯定句和答语中。KEJ易文君-文库范文网

  【专题突破】情态动词和虚拟语气密不可分,情态动词表示推测的考查,虚拟语气中对情态动词的考查,这些都是需要注意的地方,要想突破,可以从语境、语义、说话者的语气等方面着手,具体说:KEJ易文君-文库范文网

  1.根据时间确定时态、时间段KEJ易文君-文库范文网

  即要分清情态动词表推测时涉及的是现在情况还是过去情况。原则上说,若对现在情况进行推测,情态动词后接动词原形或进行式;若对过去情况进行推测,则后接动词的完成式(这通常是高考的重点);若是对正在发生的情况进行推测,后接动词的进行式;判断出时间段套用现在、过去、将来虚拟语气的句式。KEJ易文君-文库范文网

  2.充分利用句子语境、语义KEJ易文君-文库范文网

  综观历年高考英语情态动词和虚拟语气的考查情况,有相当一部分考题从本质上看都是在考查情态动词在具体语境、语义中的运用,即只要考生能弄清各个被考查情态动词的意思,就可作出正确选择。KEJ易文君-文库范文网

  3.注意分清适用句型KEJ易文君-文库范文网

  即要分清所考查的情态动词是用于肯定句型,还是用于疑问句型或否定句型,同时还要注意情态动词在某些特殊情况下所使用的特殊句型。KEJ易文君-文库范文网

  4.弄清说话者的语义、语气推断属于哪个时间段的情况,正确把握隐含、混合等虚拟语气。KEJ易文君-文库范文网

  5.掌握固定句式,从固定句式着手,套用虚拟语气句型。KEJ易文君-文库范文网

  1.—catherine, i have cleaned the room for you.KEJ易文君-文库范文网

  —thanks. you _________it. i could manage it myself. KEJ易文君-文库范文网

  a. needn’t do       b. needn’t have doneKEJ易文君-文库范文网

  c. mustn’t do       d. shouldn’t have doneKEJ易文君-文库范文网

  【解析】b 句子的语境是:“我自己能做”,所以“你本不必做的”。选a还是b呢?根据前面一句中的 have cleaned 可知,动作已经发生,所以此处谈论的是一个过去情况,故选 needn’t have done。KEJ易文君-文库范文网

  2. this cake is very sweet. you _________ a lot of sugar in it.KEJ易文君-文库范文网

  a. should put    b. could have put c. might put          d. must have putKEJ易文君-文库范文网

  a. can’t        b. mustn’t    c. needn’t             d. shouldn’t KEJ易文君-文库范文网

  参考答案和解析KEJ易文君-文库范文网

  1.【解析】c as if 引导的句子,有时用虚拟语气,有时不用。原则上说,若指事实或可能为事实,不用虚拟语气;若指现在,从句谓语动词用一般过去时(be 用 were);若指过去用过去完成时,若指将来用过去将来时或用 were to do sth. KEJ易文君-文库范文网

  2.【解析】c but for 的意思是“若不是,要不是”,用于引出与事实相反的假设,通常与虚拟语气连用。根据句中的 the help you gave me,可知它表示与过去事实相反,故选c.KEJ易文君-文库范文网

  3.【解析】b根据上文的语境可知句中的 or 隐含有一个虚拟的条件,即 or=if i didn’t forget where i read the article(要是我没忘记我在哪儿读过这篇文章的话——但事实上忘了)。KEJ易文君-文库范文网

  4.【解析】d关键信息是it looks as if he were drunk 中的虚拟语气,句子既然用了虚拟语气,也就是说,“他喝醉了”不是事实,只是他的言行好像是醉了,所以此题的最佳答案是d. KEJ易文君-文库范文网

  5.【解析】d 由于空格后的 if 条件状语从句的谓语用的是虚拟语气(这是很重要的信息),所以主句要用 would 而不用 will,即答案应选d. KEJ易文君-文库范文网

  6.【解析】c 按照英语习惯,would rather 后接that 从句时,从句谓语通常要用虚拟语气,即用过去式表示现在或将来,用过去完成时表示过去。KEJ易文君-文库范文网

  7.【解析】d insist后的从句谓语有时用“should+动词原形”这样的虚拟语气,有时不用,具体要看该谓语动词所表示的含义。一般说来,若该谓语动词所表示的动作尚未发生,或尚未成为事实,则用虚拟语气;若该谓语动词所表示的动作已经发生,或已经成为事实,则要用陈述语气。分析上题的句意,可知只有选d最合适。KEJ易文君-文库范文网

  8.【解析】b是因为时态前后有矛盾。由于主句谓语是would not have got,这表明是对过去事实作出的假设,所以从句谓语应该是 had given up,而不是像d项那样用一般过去时。另外,当虚拟条件句中有 had, should, were 等词时,通常可以省略 if,并将 had, should, were 提前置于句首。KEJ易文君-文库范文网

  9.【解析】b it’s time you did 为 it’s time you thanked aunt lucy for her present 之略。按照英语语法,it’s time 后从句通常要用过去式。KEJ易文君-文库范文网

  10.【解析】b第一空填 knew,因为 i wish 后的宾语从句要用虚拟语气(即用过去式表示现在的想法);第二空要填lives,即用陈述语气,因为 where he lives 是一个客观事实,而不是 i wish 的内容。KEJ易文君-文库范文网

  11.【解析】b 此题涉及错综时间虚拟条件句,主句与现在事实相反,条件句与过去事实相反。句意为:要不是在七岁时就迷上了 melinda cox 图书馆,我真不能想像我如今会在做什么。KEJ易文君-文库范文网

  12.【解析】a without 引出的介词短语为一个与现在事实相反的含蓄条件句。KEJ易文君-文库范文网

  13.【解析】c if only 意为“,但愿,要是……就好了”,其后的句子谓语要用虚拟语气,用以表达愿望或非真实条件,同时根据 句意可以得知从句是与过去事实相反KEJ易文君-文库范文网

  14.【解析】b本题考查虚拟语气和表语从句。在it is necessary that…句型中,从句中常常用虚拟语气,其形式为“should+动词原型”,should也可以省略。第二空考查了表语从句。that没有实际的意义,只起一个连接的作用。KEJ易文君-文库范文网

  15.【解析】b考查虚拟语气。从主句的谓语动词及句意推测应选b。其他选项不符合题意。KEJ易文君-文库范文网

  16.【解析】 b 本题考查了虚拟语气的倒装。如果虚拟语气的条件从句谓语动词中含有were, had, should,有时可将if省去,而将条件从句的主语置于were, had, should之后。KEJ易文君-文库范文网

  17.【解析】c虽然前有虚拟条件句, 后有使用了虚拟语气,但the fact不是与事实相反,而是现在的真实情况, 故不用虚拟语气。KEJ易文君-文库范文网

  18.【解析】c,表示机器什么的不能工作了。是一种关于性能方面的,很固定的用法。KEJ易文君-文库范文网

  19.【解析】c can not too...to 是词组,意思是就算怎么样也不过分。KEJ易文君-文库范文网

  20.【解析】b可是根据句子的意思。must have chosen  是本来肯定会------,故答案为b。KEJ易文君-文库范文网

情态动词 篇11

  XX高考英语备考(考点聚焦+名题导解) 情态动词¯一、考点聚焦 1、  情态动词的基本用法 (1)can、be able to 和could ①can和be able to都表示能力,意思上没多大区别。但can只有现在和过去时,而be able to则有更多的形式。但当成功地完成某一具体动作时,通常不用could而用was/were able to来表示。这时was/were able to 相当于managed to,表示经过一番努力,终于能够完成某事。如: can you use chopsticks? the wounded man still was able to get to the village and was saved in the end. ②can和could can和could都可以表示能力、技能、许可、建议或请求和可能性。但比较委婉客气地提出问题或陈述看法,一般用could,回答时则用can。如: could you help me carry the bag? can i help you? (2)may/might ①may/might表示可能,但may比might可能性大。如:-why isn’t he in class?教学资源,完全免费,无须注册,天天更新!">     he may be sick.(生病的可能性较大)—     he might be sick.(生病的可能性较小)②may/might表示“允许”,may用于现在时或将来时,might常用在间接引语中表过去时,但m 教学资源,完全免费,无须注册,天天更新!">ight也可用于现在时间,表示比较委婉的语气,回答用may。如:he says we may leave. he said we might leave. ③may / might 表示建议或请求,但might比may 更客气,意思更肯定而无过去时态的含义。                                  yes, you can / may. —may / might i use your bike?    —                                  no, you mustn’t (3)must ①must表示必须,应该,没有时态变化。如:you must do everything as i do.②must表示肯定的推测。如:the light is still on, so he must be at home.③mustn’t 表示禁止做某事。如:you mustn’t smoke in the office.(4)have tohave to 表示“必须、不得不”,是由于某种外界(客观)原因而“必须”,“不得不”做某事,也可表示经常的或习惯性的事“必须”做。have to的否定形式表示不必。have to可用于多种时态中。如:you will have to clean your own boots when you join the army.i have to be at my office every evening.(5)should / ought to①should和ought to表示应当、应该,前者比后者语气轻。如:you should / ought to work hard.②should / ought to work hard.since she is not here, whe should / ought to be in the classroom.③should / ought to的否定形式表示禁止之意。如:children shouldn’t smoke.④should可表示陈述意见,推出建议或请求;而ought to可以表示劝告之意。如:you ought to respect your parents.h e suggested that they should leave at once.(6)will / would①will 用于各种人称表示“意志”、“意愿”或“决心”等,否定式won’t + 动词。如:i will tell you all about it.tom won’t do such a thing.②will用于疑问句中,常用在第二称时表示说话人向对方提出“请求”或“询问”如:will you please tell her the news when you see her?③will 表示习惯性的动作,有“总是”、“惯于”的含义。如:fish wil l die out of water.④would 表示客气的请求、建议或意愿。如:would you please be quiet?would you like coffee?⑤would 表示过去反复发生的动作。如:when i passed my school i would see my teachers who taught me 5 years ago.(7)needneed 作“必要”讲,既可作情态动词,也可作实义动词。作实义动词时后面的动词不定式要带to,其变化与一般动词相同。如:i need to think it over.—need you go now?       —yes, i must./no, i needn’t (8)daredare表示“敢”的意思。作为情态动词时,主要用在疑问句和否定句中。dare若作实义动词,后面可带to的不定式,此时to也可以省略。dare与need的用法相似。如:how dare you say that?she doesn’t date(to)ask her father.(9)used toused to表示过去常常发生的动作或存在的习惯,但现在已不复存在了。如:he used to smoke.(10 )shall①shall作为情态动词用于第二、三人称,表示说话人的意愿,有“命令”、“警告、威胁、强制”和“允许”等意思。如:we shall do a s our teacher says.you shall have the book as soon as i finish it.②在疑问句中,shall用于征求对方的意见或请求指示,常用于第一、第三人称。如:where shall he wait for us?shall we go out for a walk?2、情态动词表示推测或判断的用法下表即是表示推测的情态动词使用的场合:KEJ易文君-文库范文网

  使 用 场 合KEJ易文君-文库范文网

  mustmust + 动词原形must have done肯定句KEJ易文君-文库范文网

  may / mightmay / might + 动词原形may / might have done肯定句、否定句KEJ易文君-文库范文网

  can /couldcan / could docan / could have done否定句、疑问名(could可用于肯定句)should用来表示一种估计的情况“按理会/估计会”should do/beshould have done肯定句、否定句、疑问句 例如:it must have rained last night.she may not be at home. = it is possible that she is not at home.she can’t be at home. = it is impossible that she is at home.they should be there right now.3、情态动词在虚拟语气中的用法情态动词用于虚拟语气中表示责备的感情色彩,用法如下:(1)should have done表示“本来应该做某事而实际上未做”,而shouldn’t have done则表示“本不应该做某事而实际上做了”。如: you should have told me about it earlier. you shouldn’t have said such words to your parents. (2)ought to have done也表示“本应该……”而ought not to have done则意为“本不应该……”。如: you ought to have told me about it earlier. you ought not to have said such words to your parents. (3)needn’t have done表示“本无必要做某事而实际上做了”。如: you needn’t have walked so quickly since time was enough. (4)could have done表示“本来有可能……而事实上未做到”。如: i could have come on time, but my car broke on the way. ù二、精典名题导解 选择填空 1. i was really anxious about you. you________home without a word. a.mustn’t have               b.shouldn’t have left c.couldn’t have left           d.needn’t have 解析:答案为b。本题考查的是情 态动词在虚拟语气中的用法。题目给出的条件是“我确实非常担心你”,因此后面可知应是责备you不应该没说一句话就离开 了。 2.—are you coming to jeff’s party? —i’m not sure. i __________ go to the concert instead. a.must           b.would          c.should           d.might 解析:答案为d。本题考查情态动词的基本用法。由题目中“i’m not sure”,表明我可能去jeff’s party,也可能去音乐会,故用might。 3. —will you stay for lunch? —sorry, ____________. my brother is coming to see me. a.i mustn’t        b.i can’t          c.i needn’t         d.i won’t 解析:答案为b。本题考查表示请求的英语口语,用will来向第二人称提问的疑问结构,是表示一种请求和意愿,是用疑问的形式来表达较为婉转的祈使语气,意思是“请你……,好吗”,对于这种问句的肯定回答是:suree! gertainly! yes, of course. i’d be glad to 等;否定回答通常是:i’m sorry, i can’t. no, i’m afraid i can’t. i’m sorry, but … i’d like to, but …等。注意情态动词表客气的用法及其在一般疑问句中的问与答。 4.—isn’t that ann’s husband over there?  —no, it         be him i’m sure he doesn’t wear glasses. a. can’t         b. must not         c. won’t        d. may not 解析:答案为a。本题考查情态动词表推测。问:那边的难道不是ann的丈夫吗?答:不是。不可能是他,我确信他不戴眼镜。 5.you          be tired-you’ve only been working for an hour. a. must not      b. won’t           c. can’t         d. may not 解析:答案为c。本题考查情态动词。句中破折号后的内容对前一句进行解释说明:你只工作了一个小时,所以你不可能累的。表否定推测时用can’t。a项表禁止(不许),b项表未来,d 项表不允许。均不可用,故选c。 6.i often see lights in that empty house. do you think i         report it to the police? a. should     b. whatever       c. whichever     d. whenever 解析:答案为a。本题考情态动词。在空房子里看到灯光,是一件奇怪而令人生疑的事,故问:你是否认为我应当把这事儿报告给警察?应用a。KEJ易文君-文库范文网
