高中英语真题:2013年高考第二轮复习英语广东版语法热点突破一、情态动词1．情态动词具有以下三个特点：（1）后面接动词原形。

（2）没有人称和数的变化。

（3）变为疑问句或否定句时不需要加助动词，而是将情态动词移至主语前变为疑问句；在情态动词后加not，构成否定句。

2．“情态动词＋have done”表示推测、必要性They must have_fallen （fall）asleep.I saw Mr. Wang just now.He couldn't have_gone （go）to Beijing.You could have done better，but you were too careless.You should have come to the meeting earlier.3．表示能力，can与be able to一般可互换，但be able to可用于将来时和完成时等时态；在表示过去具体某次能够成功做成某事时，只能用was/were able to。

4．表示请求许可，可说May/Might/Can/Could I ...？但表示给予许可时，不能用might/could，即不说you might/could。

5．must与have to的区别：must强调主观认为“必须”做某事，而have to 强调客观上要求“不得不”做某事；have to 有过去式（had to）和将来时（will have to）等时态；mustn't意为“不准”，don't have to＝needn't，意为“不必”。

另外，must还可表示“硬要，偏要”。

6．should可表示“万一，竟然”。

7．表示“应该，应当”，should和ought to可互换，只是ought to的语气稍重；should强调主观看法，而ought to强调客观要求。

8．shall在陈述句中表示说话者给对方的承诺、决心、警告、威胁等；也可在法令、条约、规章中表示强制，意为“必须，应该”。

【分析】功能：情态动词不能单独作谓语，后跟动词原形共同构成谓语。

形式：情态动词没有人称和数的变化。

否定形式是多数情态动词的否定式是在情态动词的后面加not。

时态：个别情态动词有现在式和过去式两种形式，过去式用来表达更加客气、委婉的语气。

位置：情态动词在谓语之前；谓语动词前若有助动词，则在助动词之前。

疑问句中在主语之前。

【高频考点】1.can/could表能力、请求、可能性(表示可能性用于否定句及疑问句中)；特殊句型：can not...too.../enough(再怎么……也不过分)、can't help but do sth.(不得不做某事)、can't wait to do sth.(迫不及待地做某事)。

2.may/might表较小的可能性；表示请求许可以及祝愿。

句型和搭配：may/might as well do表示“还是……好；最好……”；may well do表示“很可能”；may可以用来表示祝愿，用“may＋主语＋动词原形”结构。

May you succeed.祝你成功。

3.must表示非常肯定的推测；表“偏要；非要……不可”；mustn't意为“禁止”，表示“不必”应用needn't。

4.shall的用法用于第二、三人称的陈述句中，表命令、警告、许诺或威胁等，语气强于should；用于第一、三人称的疑问句中，表示征询意见。

5.should/ought toshould表责任、义务、劝告、建议等，意为“应该”，还可表出乎意料的语气，意为“竟然”；ought to表义务或责任，意为“应该”。

高中英语真题:2013高考英语经典陷阱题大串讲·被动语态1. “Do you like the material?”“Yes, it _________ very soft.”A. is feelingB. feltC. feelsD. is felt【陷阱】此题容易误选D，想当然地根据“这布料摸起来很柔软”这一句意，认为“布料”应是“被摸”，所以 feel 选用被动语态。

【分析】其实，此题正确答案为C，因为 feel 在此为连系动词，而连系动词均为不及物动词，不能用于被动语态，尽管有时其汉语意思有被动意味。

请看以下类似例子 (答案均为D)：(1) Her forehead _________ hot. I’m afraid she is ill.A. is feelingB. feltC. is feltD. feels(2) The new school has been completed. It _________ very bea utiful.A. is lookedB. lookedC. has lookedD. looks(3) The dish _________ nice, but the milk _________ sour.A. is smelt, is smeltB. is smelt, smellsC. smells, is smeltD. smells, smells(4) The story of his life _________ interesting.A. is soundedB. is soundingC. has soundedD. sounds2.

2013年高考真题英语单项填空题分类详解(情态动词和虚拟语气)1.(2013课标卷I)29.The door open , no matter how hard she pushed.A. shouldn’tB. couldn'tC. wouldn'tD. mightn't【答案】C【解析】考查情态动词。

此处描述主语the door的特点“老是打不开”，其固有的特性，用情态动词would （will）描述，故选C。

句意：不管她怎么用力推，门就是打不开。

2.(2013课标卷II)6.Since nobody gave him any help, he have done the research on his own.A. canB. mustC. wouldD. need【答案】B【解析】考查情态动词。

根据句意，由于没人帮他，因此他定是一个人做的那个研究。

情态动词must表肯定推测。

故选B。

A项表示"本来能够做，过去可能会做"，C项would have done用于非真实条件句虚拟语气的主句中，表示与过去相反，D项表示"需要做"均不符合语境。

句意：因为没有人给他任何帮助，他一定是独自完成这项研究的。

3.(2013北京卷)34.If we a table earlier, we couldn’t be standing here in a queue.A. have bookedB. bookedC. bookD. had booked【答案】D【解析】考查虚拟语气。

首先判断是虚拟，排除所有现在时态A和C，根据句意得知说的是过去的事情，所以选D过去完成时。

句意：如果我们当初早一些预订桌位，我们现在就不可能在这排队了。

4.(2013北京卷)35.—You needn’t take an umbrella. It isn’t going to rain.—Well, I don’t know. It do.A. mightB. needC. wouldD. should【答案】A【解析】考查情态动词。

第一个人说不会下雨，第二人回答I don’t know，因此可知，到底下不下雨是不能肯定的事情，故使用might表推测“有可能”。

【2013湖南】32.He ________ sleep, although he tried to, when he got on such a hunt for an idea until he had caught it.A.wouldn’tB.shouldn’tC.couldn’tD.mustn’t【答案】C【解析】考查情态动词。

故答案选C。

【2013江西】29.When I was a child, I ______ watch TV whenever I wanted to.A.shouldB.couldC.mustD.need【答案】B【解析】考查情态动词。

A项“应该”；B项“能够”；C项“必须”；D项“需要”，根据句意，当我还是孩童的时候，每当我想看电视的时候都能够看。

2. “I’m going to the post office.” “_________ you’re there, can you get me some stamps?”A. As子B. WhileC. BecauseD. If 【陷阱】容易误选A。

【分析】最佳答案选 Bas 不是表示“当……的时候”，其谓语是完全可以用状态动词的。

如： I went to bed early, as I was exhausted. 我很累了，所以很早就上床睡了。

(此句中的 as 表示原因，意为“因为”、“由于”) 请做以下两题，答案均选 while，不选as： (1) _________ you are at home alone, please don’t leave the door open.A. WhileB. AsC. BeforeD. How (2) _________ you are alone with her, tell her that you like her.A. WhileB. AsC. AfterD. How 3. After the war, a new school building was put up _________ there had once been a theatre.A. thatB. whenC. whichD. where 【陷阱】几个干扰项均有可能误选。

第一部分：理论知识情态动词表示说话人对动作或状态的各种观点和态度，如需要、猜测、意愿或怀疑等。

情态动词有词义，但不完全，是所谓的“辅助性”动词，在句中不能单独充当谓语。

一．情态动词的肯定形式：maymightcancouldmusthave toought towillwouldshallshouldneeddareused to二．否定式may notmight notcannot/can notcould notmust notdo not have toought not towill notwould notshall notshould notneed notdare notused not todid not use to三．简略否定式mayn't（老式英语，现在不常见）mightn'tcan'tcouldn'tmustn'tdon't have tooughtn't to（否定句中to可省略）won'twouldn'tshan't（只用于英国英语）shouldn'tneedn'tdaren'tusedn't todidn't use to情态动词除ought to, used to等外，后面只接不带to的不定式。

第二部分：课堂实战1. “I thought you wouldn’t mind.” “Well, as a matter of fact I don’t, but you _____ me first.”A. should askB. should have askedC. must askD. must have asked【答案】B【解析】should 后接动词完成式表示“本来应该做某事，结果未做”，此处含有责备之意。

2. “I called you yesterday. A woman answered, but I didn’t recognize her voice.” “Oh, it _____ my aunt Jean.”A. must beB. must have beenC. might beD. can have been【答案】B【解析】对过去情况的肯定推测，宜用“情态动词 + 动词完成式”，再根据句意，可确定答案为B。

2013---2015年高考英语分项解析精编版专题6 情态动词和虚拟语气1.【2015·北京】29．—Can’t you stay a little longer?—It’s getting late. I really _____go now, My daughter is home alone.A .mayB .canC . mustD .dare2.【2015·北京】34. If I _____it with my own eyes ,I wouldn’t have believed it.A . didn’t see B. weren’t seeing C. wouldn’t see D. hadn’t seen3.【2015·重庆】7.Without his wartime experiences, Hemingway____ his famous novel A Farewell to Arms.A.d idn’t writeB. hadn’t writtenC. wouldn’t writeD. wouldn’t h ave written【答案】D【解析】试题分析：句意：没有他战时的经验，海明威就不可能写出著名的小说永别了武器。

根据without his wartime experience没有战时的经历，可知表示对于过去的否定猜测，故主句用would have done，因此选D项。

【考点定位】考查虚拟语气【名师点睛】虚拟语气是一种动词形式，表示说话人的一种愿望，假设，怀疑，猜测建议等含义，表示的含义不是客观存在的事实，此类的题目一般难度不大，主要找对时间状语，并且看分清时间状语与主句还是从句有关系，再来确定用对现在，过去还是将来的虚拟。

4.【2015·重庆】12. You ____ be Carol. You haven’t changed a bit after all these years.A. mustB. canC. willD. shall5.【2015·浙江】4.

It costs!A .must B. may C. can D. will【答案】A【解析】试题分析：考查情态动词。

【英语】2013高考英语经典陷阱题大串讲：it用法1.Everyone knows that _________ is dangerous to play with fire, but _______ __ is difficult is to prevent children from playing with fire.A.i t,itB.wh a t,wh a tC.it, w h a tD. what, it【陷阱】很容易误选B，认为两空均考查形式主语。

【分析】最佳答案是C，第一空填形式主语，真正的主语是其后的不定式 to play wit h fire。

第二空填what，what is difficult 是主语从句，注意what is difficult 后的谓语动词is。

请做以下类似试题：(1)I know _________ is important to know my own limitations, but _________ is difficult is to help others to know their own limitations.A.i t,itB.wh a t,wh a tC.it, w h a tD. what, it(2)Yes, _________ is difficult to find a job nowadays, but _________ is more difficult is try to find such a job with a high salary but little things to d o.A.i t,itB.wh a t,wh a tC.it, w h a tD. what, it2.I dislike ______ when others laugh at me in public or think poorly of meb ehind.A.t h a tB.t h o s eC.i tD. them【陷阱】几个干扰项均有可能误选。

根据句意：如果我们早点订桌的话，我们就不可能在这里站着排队了。

可知if从句是对过去的虚拟，用过去完成时态。

【2013福建】30. ----Do you think George has passed the driving test?----No. If so, he ______ his car to our college yesterday.A. would driveB. droveC. would have drivenD. had driven【答案】C【解析】考查虚拟语气。

根据句意，如果这样的话（乔治已经通过驾照考试），他昨天就驾车来我们大学了，可知是对过去的虚拟。

If so= If he had passed the driving test，主句使用情态动词+ have done。

故答案选C。

【2013江苏】30. I should not have laughed if I you were serious.A. thoughtB. would thinkC. had thoughtD. have thought【答案】C【解析】考查虚拟语气。

此处为if虚拟条件句，其主句使用的是should have done，可知是对过去的虚拟，故从句用过去完成时态表示对过去的虚拟。

【2013陕西】12. My mom suggests that we eat out for a change this weekend.A. shouldB. mightC. couldD. would【答案】A【解析】考查虚拟语气。

1.“Mike is often absent from class.” “Tell him he _________answer for it if he go es on behaving like that.”A.shallB.willC.wouldD.can【陷阱】几个干扰项均有可能误选。
