　　要点精析

　　一、倒装

　　1．完全倒装

　　谓语动词完全搬到主语之前的句子，便是完全倒装句。这类句型主要有两种：

　　(1)表示方式或方位的副词或介词短语，如here, there, now, then, up, down, in, away, off, out, in the room, on the wall等，置于句首时。

　　In a lecture hall of a university in England sits a professor.

　　在英格兰一所大学的讲堂里坐着一位教授。

　　South of the river lies a small factory.

　　一个小型工厂坐落在河的南岸。

　　Here is the book you want.

　　你要的书在这儿。

　　Then came the order to take off.

　　起飞的命令到了。

　　Now comes your turn.

　　现在轮到你了。

　　注意：上述情况中，若主语是人称代词，则不用倒装。

　　Away they went.

　　他们走了。

　　Over it turns!

　　它翻过来了。

　　例　(2009·上海)Hearing the dog barking fiercely, away_____ ___.

　　A. fleeing the thief

　　B. was fleeing the thief

　　C. the thief was fleeing

　　D. fled the thief

　　解析：本题考查了全部倒装句。句意：听到狗的狂叫声，小偷逃掉了。表地点方位的副词away放于句首时，句子要全部倒装。正常的语序是“The thief fled away.”故选D。

　　答案：D

　　(2)表语位于句首时，其倒装结构为“表语＋连系动词＋主语”。

　　Present at the meeting were some scientists from China.

　　许多来自中国的科学家出席了会议。

　　Gone are the days when we were poor.

　　我们贫穷的日子一去不复返了。

　　2．部分倒装

　　(1)only修饰副词、介词短语或状语从句，且放在句首时。

　　Only then did we decide to answer violence with violence.

　　直到那时，我们才决定以暴制暴。

　　Only in this way can we learn English well.

　　只有以这种方法，我们才能学好英语。

　　Only when he returned did we find out the truth.

　　只有当他回来时，我们才能查明事实真相。

　　注意：only修饰主语时，句子不可倒装。

　　Only you can solve the problem.

　　只有你能解决这个问题。

　　例　(2011·新课标，28)Only when he reached the tea­house ________ it was the same place he'd been in last year.

　　A．he realized

　　B．he did realize

　　C．realized he

　　D．did he realize

　　解析：本题考查倒装句。句意：只有当他到达茶屋时，他才意识到这和他去年去的是同一个地方。“only＋状语”置于句首时，句子用部分倒装语序，故D项正确。

　　答案：D

　　(2)否定副词never, nor, not, hardly, little, seldom, scarcely, rarely及表否定意义的介词短语at no time, under/in no circumstances, in no case, by no means, on no condition等置于句首时。

　　Never before have I seen such a moving film.＝I have never seen such a moving film before.

　　以前我从未看过这么感人的电影。

　　Not a single mistake did he make.＝He didn't make a single mistake.

　　他一个错误也没犯。

　　例　(2011·福建，29)—It's nice.Never before ______such a special drink!

　　—I'm glad you like it.

　　A．I have had

　　B．I had

　　C．have I had

　　D．had I

　　解析：本题考查倒装与动词时态。句意：——太好喝了。我以前从未喝到这么特别的饮料！——你能喜欢我很高兴。否定词never置于句首，句子需用部分倒装，排除A，B两项，又由时间状语before可知，句子要用现在完成时，故C项正确。

　　答案：C

　　(3)hardly...when..., no sooner...than..., not only...but also...等引导两个分句时，前一个分句用部分倒装，后一个分句不变。但当neither...nor...引导两个分句时，两个分句都要部分倒装。

　　Hardly had he begun to speak when his father stopped him.

　　他刚一开始说话他父亲就制止了他。

　　Neither do I know, nor does she.

　　我不知道，她也不知道。

　　(4)so/neither/nor置于句首，意为“也(不)”，表示前面所说的情况也适用于另一个人或事物时，要用部分倒装，其句型为：so/neither/nor＋be动词/助动词/情态动词＋主语。so与前面的肯定句呼应；neither, nor与前面的否定句相呼应。

　　They love having lots of friends; so do those with disabilities.

　　他们喜欢拥有许多朋友，残疾人也是如此。

　　I don't know who he is, nor do I want to know.

　　我不知道他是谁，我也不想知道。

　　注意：so表示“是的，确实”时，主谓语不倒装。

　　—It is too hot.天太热了。

　　—So it is. 是啊，的确很热。

　　(5)在so/such...that...句式中，如果so/such引导的部分位于句首时，主句中的主语和谓语需要部分倒装。

　　So dark was it that he couldn't see the faces of his companions.

　　天这么黑，他看不见同伴的脸。

　　她如此害怕以至于一句话也说不出来。

　　So loudly did he speak that even the people in the next room could hear him.

　　他说话声音如此大以至于隔壁的人都能听见。

　　例　(2010·东城检测)________that all mountain roads were closed.

　　A．So became the dangerous weather

　　B．So dangerous did the weather become

　　C．So dangerous became the weather

　　D．Dangerous the weather became so

　　解析：考查倒装和固定句式。句意：天气如此危险，所有的山路都被封闭了。在“so...that...”结构中，若so位于句首，从句要倒装。本句相当于“The weather became so dangerous that all mountain roads were closed.”。故选B。

　　答案：B

　　(6)以as引导的让步状语从句，其表语应提到句首，其余部分不变。如果从句的表语是个名词时，要把名词前的冠词去掉。though引导的让步状语从句也可以用这种形式，但也可以用正常结构。其结构一般为“adj./adv./v./v.­ed/v.­ing/n.＋as/though＋主语＋谓语”。

　　Young as/though she is, she has seen much of the world.

　　她虽然年轻，但却见过很多世面。

　　Woman as she is, she is courageous.

　　她虽然是女人，但却很勇敢。

　　例　(2011·新课标，22)Try ________ she might, Sue couldn't get the door open.

　　A．if

　　B．when

　　C．since

　　D．as

　　解析：本题考查连词的用法。句意：尽管苏尝试了，但她还是打不开门。根据句子结构可知，本题考查as引导的让步状语从句，要用倒装语序。其结构为：adj./adv./v./v.­ed/v.­ing/n.＋as/though＋主语＋谓语，故D项正确。

　　答案：D

　　(7)省略if的倒装句型。如果虚拟语气的条件句中谓语有系动词were，助动词had或情态动词should等，可省去if，把were, had或should移到主语之前。

　　Were I you(＝If I were you), I would take his advice.

　　如果我是你，我会接受他的建议。

　　Should it rain tomorrow(＝If it should rain tomorrow), the sports meeting would be put off.

　　万一明天下雨，运动会就会推迟举行。

　　二、强调

　　强调句的基本句型是“It is/was＋被强调的部分＋that/who＋其他部分”。被强调的部分可以是主语、宾语和状语等。强调句型的使用特点主要有以下几个方面：

　　1．被强调的是状语或状语从句时，要用that引导从句，而不能用which，而且通常不能省略。

　　It was in the park that I met him.

　　我是在公园里遇到他的。

　　It was in 1964 that the first telephone satellite was set up by the Group of 17 Countries.

　　17国集团发射第一颗电话卫星是在1964年。

　　例　(2011·重庆，32)—Have you seen the film Under the Hawthorn Tree?

　　—Of course, I have. It was in our village ________ it was made.

　　A．that

　　B．where

　　C．when

　　D．which

　　解析：本题考查强调句型。句意：——你看过电影《山楂树之恋》吗？——当然看过，就在我们的村庄拍摄的。其结构为：It is/was＋被强调部分＋that＋其余部分。此处强调地点状语。

　　答案：A

　　2．被强调的是人时，引导词可用who，也可用that。

　　Was it you that/who let out the secret to her?

　　是你把这个秘密泄露给她的吗？

　　注意：当被强调的是主语时，代词要用主格形式。

　　It was I who put forward the theory first.

　　是我最先提出这个理论的。

　　3．被强调的不管是单数还是复数名词，主句的be动词都用单数is或was。

　　It was Madame Curie and her husband who discovered radium.

　　是居里夫人和她的丈夫发现了镭。

　　It is the PLA men who/that are safeguarding our country day and night.

　　是解放军战士日夜保卫着我们的祖国。

　　4．对not...until...时间状语从句进行强调时，其句型是：It is/was not until...that从句，即not和until在强调句中总是紧挨着的。注意习惯上不用not till，而且从句不能用when引导。

　　It was not until the last operation was finished that Bethune left the battle hospital.

　　直到做完最后一个手术白求恩才离开战地医院。

　　5．强调句的疑问形式。

　　When was it that he made up his mind to take this course?

　　他什么时候决定选修这一课程的？

　　Why is it that he doesn't like the book?

　　他为什么不喜欢这本书？

　　Was it in 1939 that the Second World War broke out?

　　第二次世界大战是在1939年爆发的吗？

　　Who was it that broke the window?

　　打破窗户的是谁？

　　When was it that you called me yesterday?

　　你昨天给我打电话是什么时候？

　　What is it that you want me to do?

　　你要我干什么？

　　例　(2010·江西九校一模)—________you found out the accident which happened a month ago?

　　—By looking into it.

　　A．It was where that

　　B．Was it how that

　　C．How was it that

　　D．Was it what that

　　解析：考查强调句型在疑问句中的用法。根据回答可以知道应该用how，而在特殊疑问句中语序应该用部分倒装，强调方式的搭配为How is/was it that...。故选C。

　　答案：C

　　例　(2010·石家庄检测)I still remember how many years ago________I last met her in the countryside.

　　A．when it was

　　B．was it that

　　C．when was it

　　D．it was that

　　解析：考查强调句型。remember后的部分是宾语从句，从句中含有一个强调句型，被强调部分是how many years ago。故选D。

　　答案：D

　　6．强调句型与It is/was＋时间＋when从句。

　　在上述句型中it指时间，when引导的是时间状语从句。注意两种句型“时间”表达方式的不同。

　　It was at midnight that I got back home yesterday.

　　昨天晚上我半夜才回到家。

　　It was midnight when I got here yesterday.

　　昨天当我到达这儿时，已是半夜了。

　　三、省略

　　1．状语从句的省略

　　(1)有些时间、条件、方式、让步状语从句中，如果从句的主语和主句主语一致或从句的主语为it，而且从句的谓语动词又包含be，就可以省略从句中的“主语＋be”部分。

　　While(I was)in Beijing, I paid a visit to the Great Wall.

　　在北京时，我去游览了长城。

　　If(you are)asked, you may come in.

　　如果被叫到，你可以进来。

　　(2)还有诸如：if so(如果如此)；if any(如果有)；if in need(如果需要)；if necessary(如果有必要); if not(如果不的话)；if ever(如果曾经的话)；if possible(如果可能的话)。

　　Errors, if(there are)any, should be corrected.

　　如果有什么错误，就应当改正。

　　Come tomorrow if(it is)possible.

　　有可能的话明天来。

　　Get up early tomorrow, if not(you don't get up early), you will miss the first bus.

　　明天早点起床，如果不的话，你会错过早班车。

　　He may not be at home then, if so(he is not at home)，leave him a note.

　　那时他可能不在家，如果这样给他留下字条吧。

　　2．I'm afraid, I think, I believe, I hope, I guess等作答句，后面跟so与not分别等于肯定或否定，宾语从句可省去。

　　—Do you think it will rain?

　　你认为将会下雨吗？

　　我希望不下雨。

　　—Do you believe our team will win?

　　你相信我们的队会赢吗？

　　—I guess so(that our team will win)．

　　我猜会赢。

　　3．不定式省略，单独使用不定式符号to

　　(1)用来代替动词不定式后被省略的动词，常在be afraid, expect, forget, hope, intend, like, love, mean, prefer, refuse, seem, try, want, wish等的后边。

　　I asked him to see the film, but he didn't want to.

　　我请他去看电影，但他不想去。

　　(2)在have, need, ought, be going, used等后面。

　　(3)在某些形容词glad, happy, pleased, delighted等后面。

　　—Will you join in the game?

　　你是海员吗？

　　—No, but I used to be.

　　不，但我过去是。

　　例　(2009·江苏)—What' s the matter with Della?

　　—Well, her parents wouldn't allow her to go to the party, but she still ________.

　　A．hopes to

　　B．hopes so

　　C．hopes not

　　D．hopes for

　　解析：考查不定式的省略。动词不定式省略时，要保留动词不定式符号to。

　　答案：A

　　四、反意疑问句

　　1．陈述部分含有must的反意疑问句

　　must作“一定，准是”讲，可首先将句子改为“I am sure that”从句，反意疑问部分的动词形式根据be sure后的宾语从句的谓语动词形式确定。

　　(1)You must be hungry now，________？→I am sure that you are hungry, aren't you？→You must be hungry now, aren't you?你一定饿了，是吗？

　　(2)You must have heard about it，________？→I am sure that you have heard about it, haven't you？→You must have heard about it, haven't you?

　　你一定听说过这事了，是吗？

　　你昨晚一定看足球赛了，是吗？(陈述部分有表示过去的时间状语last night)

　　2．主句谓语动词think, believe, suppose, guess, expect, imagine的主语为第一人称时，疑问部分的主语和谓语动词与宾语从句的主语和谓语保持一致；若他们的主语为第二、三人称时，后面的反问部分由主句来决定。

　　I don't believe he will succeed, will he?

　　我认为他不会成功，是吗？

　　Tom doesn't believe Jack will succeed, does he?

　　汤姆不相信杰克能成功，对吗？

　　3．祈使句的反意疑问句

　　祈使句中的后半部分附加问句，不表示反意，而表示一种语气。其结构为：

　　(1)否定祈使句，＋will you?

　　(2)肯定祈使句，＋will/won't you?

　　Let's...，＋shall we?

　　Let us...，＋will you?

　　Let＋第三人称．..，＋will you?

　　Open the door, will/won't you?

　　打开门，好吗？

　　Let's go out for a walk, shall we?

　　我们出去散步，好吗？

　　Let us go home now, will/won't you?

　　现在，(您)让我们回家，好吗？

　　A．could he

　　B．didn't I

　　C．didn't you

　　D．could they

　　解析：本题考查反意疑问句。句意：我告诉他们并不是所有的人都和他跑得一样快，是吗？主从复合句变反意疑问句时，反问部分与主句一致。故B项正确。

　　答案：B

　　运用提升

　　1．(2011·湖南，32)Only after

　　they had discussed the matter for several hours ________ a decision.

　　A．they reached

　　B．did they

　　reach

　　C．they reach

　　D．do

　　they reach

　　答案：B　本题考查倒装句式。句意：他们只有在讨论这个问题几个小时后，才决定下来。“only＋状语”放在句首，主句的谓语动词需用部分倒装形式，由句中的had discussed可知此处应用一般过去时态。

　　2．(2011·湖南，35)It's not what we do once in a while ________ shapes our lives, but what we do consistently.

　　A．which

　　B．that

　　C．how

　　D．when

　　答案：B　本题考查强调句式，句意：不是我们偶尔而是我们始终如一做的事情塑造了我们的生活。此处构成It is...that强调句式。

　　3．(2011·辽宁，33)______a strange plant! I've never seen it before.

　　A．Which

　　B．What

　　C．How

　　D．Whether

　　答案：B　本题考查感叹句。句意：多么奇怪的植物！我从来没见过。感叹句结构为：

　　what＋＋主语＋谓语！　How＋故B项正确。

　　4．(2011·四川，15)Was it on a lonely island ________ he was saved one month after the boat went down?

　　A．where

　　B．that

　　C．which

　　D．what

　　答案：B　本题考查强调句型。句意：他是在那艘船沉下去一个月后，被人从那座孤岛上救下来的吗？it is... that...为常用的强调句型，被强调的部分置于it is 之后。

　　5．(2011·陕西，23)It is not how much we do but how much love we put into what we do________benefits our work most.

　　A. who

　　B. which

　　C. that

　　D. what

　　答案：C　考查强调句型。句意：不是我们做了多少而是我们向我们所做的投入了多少热忱使我们的工作最受益。去掉it is 和空白处以后，句子可还原为Not how much we do but how much love we put into what we do benefits our work most，由此可见本题考查强调句式“It is＋被强调部分(Not how much we do but how much love we put into what we do)＋that＋其他”，所以C项正确。该结构中只有被强调部分是人时才可用who替代that，其他情况得用that。

　　6．(2011·北京，31)The shocking news made me realize ________ terrible problems we would face.

　　A. what

　　B. how

　　C. that

　　D. why

　　答案：A　本题考查宾语从句引导词的选择。句意：这条令人震惊的消息使我意识到我们将面临多么可怕的问题。根据句意，空白处表示“多么”，有感叹的意味，故排除C、D两项；what引导感叹句时，中心词是名词；how引导感叹句时，中心词是形容词或副词；本题中心词是problems，故用what。

　　7．(2011·海淀第二学期期末，34)Mr. Smith is still not so familiar with the city because it was only two months ago, in March, ________ he started working here.

　　A．before

　　B．when

　　C．that

　　D．which

　　答案：C　句意：Smith先生现在对这座城市依然不熟悉，因为在两个月前也就是三月份他才开始在这里上班。在原因状语从句中考查强调句式。去掉强调框架后句子的主干为：He started working here only two months ago.。

　　8．(2011·海淀期中，24)Although ________ considerable success as an artist, the young man keeps working hard.

　　A．achieving

　　B．achieved

　　C．to achieve

　　D．having achieved

　　答案：D　句意：尽管作为艺术家，他已经取得了相当大的成功，但这位年轻人继续努力工作。考查非谓语动词。此处的although having achieved相当于although the young man has achieved，故选D。句首表示让步的连词although容易影响考生对句子结构的理解。

　　9．(2011·东北三省四市联考，24)If ________ unsolved, this may lead to more serious problems.

　　A．making

　　B．remained

　　C．left

　　D．taking

　　答案：C　句意：如果这个问题不解决，可能会导致更严重的问题。考查非谓语动词及省略句。句子补全为“If it is left unsolved...”故选用过去分词left表被动。易错选B。误认为句子原形是“If it remained unsolved...”，但没有注意动词remain的形式而误选。需用remaining才行。

　　10．(2011·太原基础知识测试，22)—________， ask Mary to help you.

　　—Don't worry. I can make it myself.

　　A．If not

　　B．If necessary

　　C．If only

　　D．In anything

　　答案：B　句意：——如果有必要的话，请求Mary帮助你。——别担心，我自己能做成。考查句子的省略。if necessary为if it is necessary的省略形式；if not中的not代指上文中出现的否定意义的句子。易错选A。误选的原因是没有意识到代词not是代指上文中出现的否定意义的句子，而对话中空格前没有否定句，没有可替代的对象。

　　11．(2011·济南4月模拟，28)Is it that you often play computer games ________ worries your parents?

　　A．why

　　B．that

　　C．which

　　D．what

　　答案：B　句意：是你经常玩电脑游戏使你的父母感到担忧吗？考查强调句的一般疑问句形式。被强调的是主语从句that you often play computer games。

　　12．(2011·江南十校联考，34)The Greens must have been to 2010 Shanghai Expo, ________ they?

　　A．hadn't

　　B．didn't

　　C．can't

　　D．weren't

　　答案：D　句意：格林夫妇肯定曾去过2010上海世博会，是不是？考查反意疑问句。由题干中的must have been to...可知此处表示“对过去曾经发生情况的推测”，而且must后是be动词的完成式，需借助be动词的某种形式构成简略问句，故选D。如：You must be students, aren't you?

　　13．(2011·合肥第二次质检，26)Mary enjoys home­made food, so she seldom, ________， eats out.

　　A．if never

　　B．if any

　　C．if not

　　D．if ever

　　答案：D　句意：Mary喜欢吃家里做的饭，因此她很少外出吃饭，如果曾经外出吃饭的话次数也不多。考查句子的省略形式。if ever意为“如果有过的话，如果发生过的话”相当于现在完成时句子的省略式。如：He was a great musician if ever there was one.如果曾经有过伟大的音乐家，那他就是一个。She seldom, if ever, goes to the cinema.她难得看电影。易错选B。if any为if there are any的省略形式，意为“如果有的话也不多”。如：There are few trees on the playground if any.操场上如果有树的话，也不多。忽略语境中的信息词seldom，若选if any则意思和seldom重复而造成误选。

　　14．(2011·苏锡常镇一调，26)It was only as I got older ________ I got more curious about my background.

　　A．that

　　B．than

　　C．then

　　D．when

　　答案：A　句意：仅当我逐渐长大时，我才对我的来历好奇起来。考查强调句型。本句是对时间状语从句only as I got older的强调。分析句子成分可知，去掉it was和选项，句子剩下部分是完整的，符合强调句的特点。

　　15．(2011·杭州质检二，19)Be careful when you deal with this chemical, as it will explode when ________ to sunlight.

　　A．being exposed

　　B．to expose

　　C．exposing

　　D．exposed

　　答案：D　句意：处理这种化学物质时要小心，因为它暴露在阳光下时会爆炸。考查时间状语从句的省略。补全后为：...when this chemical is exposed to sunlight.当时间状语从句的主语和主句主语一致，且谓语动词中含be动词的某种形式，为简洁起见常把从句的主语和be动词一起省略。

　　16．(2011·西安八校联考，22)I won't go there. You know, it is already 9 in the evening. ________， it is raining hard.

　　A．Therefore

　　B．However

　　C．Besides

　　D．That is

　　答案：C　句意：我不会去那儿。你知道，已经晚上九点了。此外，天正下着大雨。考查副词和插入语。besides“此外”表示递进关系；therefore“因此，所以”表示因果关系；however“可是，然而”表示转折关系；that is＝that is to say“也就是说”作插入语。

　　17．(2011·乌鲁木齐二诊，26)I've never opposed the project; ________， I've always supported it.

　　A．on the other hand

　　B．on the contrary

　　C．out of the question

　　D．in other words

　　答案：B　句意：我到现在为止从来没有反对过这一方案；相反地，我总是支持它。考查介词短语辨析。on the contrary“正相反”符合逻辑和语境。on the other hand“在另一方面”；out of the question“不可能”；in other words“换句话说”。

　　18．(2011·成都三诊，15)It was not until she had arrived home ________ her appointment with the doctor.

　　A．when she remembered

　　B．and she remembered

　　C．did she remember

　　D．that she remembered

　　答案：D　句意：直到走到家，她才记得和医生有约。考查强调句式，本题被强调部分为not until状语从句，构成It is not until...that...“就是直到……才”。

　　19．(2011·成都三诊，17)It was really dangerous. One more step, ________ the baby would have fallen into the well.

　　A．and

　　B．or

　　C．so

　　D．but

　　答案：A　句意：实在太危险了，再往前走一步，那孩子就会掉进井里。考查典型句式：名词短语/祈使句(相当于一个条件句)＋and/or＋一般将来时的陈述句。此处的名词短语one more step相当于一个祈使句(或条件状语从句的省略形式)。

　　20．(2011·泰州二模，31)While ________ on the ladder, please don't move your body.

　　A．stand

　　B．stood

　　C．being standing

　　D．standing

　　答案：D　考查状语从句的省略。while后省略了句子的主语you和be动词are，所以选D。

　　21．(2011·西安二模，12)—Hi, Kathy. We're going to have a party this Saturday. Will you come?

　　—________. What time?

　　A．I suppose so

　　B．I'd love to

　　A．how; that

　　B．that; what

　　C．whether; what

　　D．what; that

　　答案：D　考查强调句型和名词性从句。分析句子结构可以看出，此处为强调句型，强调主语；第一个词what作do的宾语，引导一个主语从句。

　　23．(2011·贵阳一模，18)I told you that you shouldn't waste your time playing the games, ________？

　　A．didn't I

　　B．did I

　　C．should you

　　A．It was while

　　B．As soon as
