四六级常考英语语法15要点

强调句百科名片基本语法强调句是一种修辞，是人们为了表达自己的意愿或情感而使用的一种形式。

目录定义常用句型强调形式语法结构练习编辑本段定义强调句(The Emphatic Pattern)是一种修辞，是人们为了表达自己的意愿或情感而使用的一种形式。

通过各种方式对句子中的某个部分进行强调，从而起到修辞的作用。

英语常用的强调结构是"It is (was)+被强调部分(主语、宾语或状语)+who (that)..."。

一般说强调句来,被强调部分指人时,用who;指事物时用that,但that也可以指人。

在美国英语中指事物时常用which来代替that。

编辑本段常用句型1. 陈述句的强调句型It is/ was + 被强调部分（通常是主语、宾语或状语）+ that/ who （当强调主语且主语指人）+ 其他部分。

例子 It was yesterday that he met Li Ping.2. 一般疑问句的强调句型同上，只是把is/ was提到it前面。

例子 Was it yesterday that he met Li Ping?3. 特殊疑问句的强调句型被强调部分（通常是疑问代词或疑问副词）+ is/ was + it + that/ who + 其他部分？例子 When and where was it that you were born?4.not … until …句型的强调句A. 句型为：It is/ was not until + 被强调部分 + that + 其他部分普通句：He didn't go to bed until/ till his wife came back.强调句：It was not until his wife came back that he went to bed.B. 注意：此句型只用until，不用till。

但如果不是强调句型，till, until可通用；因为句型中It is/ was not ... 已经是否定句了，that后面的从句要用肯定句，切勿再用否定句了。

四级语法总结一：时态：所谓的"时态"，就是时间+状态。

谓语动词的时态见下表：1．主动形式2．被动形式❖时间状语从句当中的时态：一般过去时所有的过去用一般现在时表示现在和将来现在完成时现在完成和将来完成一．非谓语动词一．不定式：一）不定式的常考形式：1)一般形式：He decided to work harder in order to catch up with the others.被动形式: He preferred to be assigned some heavier work to do.语法功能：表示与谓语动词同步发生2)完成形式：He pretended not to have seen me.被动形式：The book is said to have been translated into many languages.语法功能：表示发生在谓语动词之前二）不定式常考的考点：1）不定式做定语----将要发生2）不定式做状语----目的3）不定式充当名词功能---To see is to believe.三)不定式的省略1)感官动词 see, watch, observe, notice, look at, hear, listen to, smell, taste, feel+ do表示动作的完整性，真实性；+ doing表示动作的连续性，进行性I saw him work in the garden yesterday.昨天我看见他在花园里干活了。

(强调"我看见了"这个事实)I saw him working in the garden yesterday.昨天我见他正在花园里干活。

（强调"我见他正干活"这个动作）❖感官动词后面接形容词而不是副词：The cake tastes good; It feels comfortable.2) 使役动词 have bid make let 等词后不定式要省略但同1)一样被动以后要还原toI ‘d like to have John do it.I have my package weighed.Paul doesn’t have to be made to learn.3) help help sb do help sb to do help do help to do四)有些动词后只跟不定式如：want，wish，hope，manage，promise，refuse，pretend，plan， offer，decide，agree，expect allow sb to do, cause sb to do , permit sb to do, enable sb to doforce sb to do. be more likely to do love to do warn sb to do be able to dobe ambitious to do. begin to do . start to do五) 有的时候to后面要接-ing形式accustom (oneself) to; be accustomed to; face up to; in addition to; look forward to; object to; be reduced to; resign oneself to; be resigned to; resort to; sink to; be used to; be alternative to; be close/closeness to; be dedication/dedicated to; be opposition/opposed to; besimilarity/similar to.三、need/want 后的-ing形式具有被动的意思。

英语四六级语法总结大全不论是在四级考试中，还是在英语学习中，语法部分始终都是一切的基础，今天小编就给大家分享一下英语的知识大全，大家可以看看哦英语知识一、虚拟语气。

应着重复习能引起虚拟语气的某些介词、介词短语和连词(如lest, in case, otherwise等);一部分表示建议、主张、命令等概念的词语，由于本身隐含说话人的主观愿望，其后的主语从句、宾语从句、同位语从句往往采用“should+动词原形”;虚拟倒装句;在would rather, wish, as if, it’s time that等句型中使用适当形式表达主观愿望;混合虚拟句。

二、独立主格题。

一般说来，在句子中没有连接词的情况下，逗号是无力连接两个句子的，其中一个分句要么是非谓语形式，要么是独立主格结构。

两种结构都做状语，不同的是独立主格结构有自己的逻辑主语。

三、时态。

英语中共有16个时态。

四级考试中出现最多的是将来完成时、现在完成时、过去完成时和完成进行时。

四、名词性从句。

形容词性的定语从句是考核的重点，用什么引导词，引导词前面的介词形式，引导词在从句中做什么成分，从句的语序等均有可能成为考点。

此外，主语从句、同位语从句、宾语从句也应适当复习。

五、主谓一致。

这类考题灵活性大，需要根据实际情况判断谓语动词的单复数形式。

一部分具有生命意义的集合名词做主语时谓语动词多采用复数形式，如people, poultry, militia等;用and连接的成分表单一概念时谓语动词用单数;就近原则：主语中含有某些连词(如as well as, besides, in addition to等)时，谓语动词的数同第一个主语保持一致。

六、倒装结构。

分为全部倒装和部分倒装。

那些否定词(组)、介词短语能引起倒装句，部分倒装和全部倒装有和区别，as在倒装结构中的用法及意义等等，都是考生应当重视的地方。

七、非谓语动词。

①根据非谓语动词同其所修饰的名词或逻辑主语的一致关系，确定使用主动语态或被动语态，然后考虑采用现在分词、现在分词被动式或过去分词;②非谓语动词同主句谓语动词动作发生的先后关系。

at.在see,hear,feel,watch,notice等动词后,及可用现在分词,也可用不定式构成宾语补足语.用现在分词时,表示动作正在发生,用不定式时表示动作发生了.Do you hear someone knocking at the door?Yes,I did.I heard him knock three times.f)作状语:现在分词作状语时,通常都表示主语正在进行的另一动作,来对谓语表示的主要动作加以修饰或作为陪衬.I ran out of the house shouting.I got home,feeling very tired.Driving to Chicago that night,I was struck by a sudden thought.现在分词短语有时可以用作状语表示原因,相当于一个表示原因的状语从句.get in touch with her.Not knowing her address,we couldn’ｔSeeing nobody at home,she decided to leave them a note.want to go to the cinema.Having already seen the film twice,she didn’ｔ现在分词短语有时可用作时间状语,相当于when引起的从句:help thinking of those memorable days they spent together.Seeing those pictures,he couldn’ｔ如果两个动作是完全同时发生的,多用when或while加分词这种结构.Be careful when crossing the street.When leaving the airport,they waved again and again to us.She got to know them while attending a conference in Beijing.3)前面带有代词或名词的动名词结构:一个动名词前面可以加一个物主代词(或名词的所有格结构),来表示这个动名词逻辑上的主语.Their coming to help was a great encouragement to us.Our sole worry is your relying too much on yourself.Do you mind my reading your paper?They insisted on my staying there for supper.如果不是在句子开头,这个结构常常可以用名词的普通格(或人称代词宾格),这比用所有格更自然一些.I don’ｔm ind him going.She hates people losing their temper.help,mind,admit,enjoy,leave off, 4)只能用动名词作宾语的动词:suggest,finish,avoid,stop,can’ｔrequire,postpone,put off,delay,practise,fancy,excuse,pardon,advise,consider,deny,endure,

notebooks with me.I regret not having accepted your advice.I regret to say I haven’ｔgiven you enough help.want(need)to come.She doesn’ｔThe house wants(needs)cleaning.We must try to get everything done in time.t ry doing the work some other way.Let’ｓ6)悬垂修饰:分词作状语时,表示的必须是主语的一个动作或状态.Walking through the park,we saw a lot of flowers.(walking是we的动作,正确)Walking through the park,the flowers looked very beautiful.(错误)Standing on the tower,we could see the whole city.(正确)Standing on the tower,the whole village could be seen.(错误)3.分词1)意义:过去分词通常来自及物动词,带有被动意义和完成意义;而现在分词有的来自及物动词,有的来自不及物动词,通常带有主动意义和未完成意义.frozen food a freezing winda bored traveller a boring journeya lost cause a losing battlea conquered army a conquering armya finished article the last finishing touchthe spoken word a speaking birda closed shop the closing houra recorded talk a recording machine来自不及物动词的过去分词很少能单独用作前置修饰语,能作这样用的仅限于下面几个词,仅表示完成意义,不表示被动意义.the risen sun,fallen leaves,faded/withered flowers,returned students,retired workers,departed friends,escapedprisoners,the vanished jewels,newly-arrived visitors用作后置修饰语的过去分词一般都带有修饰语或其他成分,在意义上相当于关系分句.Most of the people invited to the reception were old friends.2)句法作用a)作定语:distinguished guest贵宾,unknown heroes无名英雄,armed

marked rise in total production.间或也可表示一个假设的情况,相当于一个条件从句.Given closer analysis,we can see this is totally wrong.偶尔也可用来代替一个“让步”状语从句.Picked20years a year,it grows tired only after40or50years.d)独立结构:在用分词短语作状语时,它逻辑上的主语一般必须与句子的主语一.致.但有时它也可以有自己独立的逻辑上的主语,这种结构称为独立结构,一般表示一种伴随的动作或情况.He rushed into the room,his face covered with sweat.有时可以表示时间:Late that autumn,his work finished,he prepared to return to his institute.表示原因:Her eyesdimmed with tears,she did not see him enter.条件:All things considered,her paper is of greater value than yours.Ⅲ虚拟语气1.that从居中:1)wish,would

talked(are talking)as if they had been friends for years.It seems as if it was(were)spring today.He acts(acted)as if(though)he were(was)an expert.3)以lest,for fear that和in case引起的从句(这时谓语多用should+动词原形):He took his raincoat with him lest it should rain.He put his coat over the child for fear that(或lest)he should catch cold.I’ll keep a seat for you in caseyou should needit.4)以whatever,whoever,no matter what这类代词或词组引起的从句(这时,谓语多用may加动词原形构成):Whatever defects he may have,he is an honest man.Come what may,we will go ahead.不管发生什么情况,我们都要干下去.I accept that he is old and frail;be that as it may,he’ｓs till a good politician.我承认他年老体衰,然而尽管如此,它仍是优秀的政治家.3.条件句1)虚拟条件句主要有下面两类:a)表示现在及将来情况(表示纯然假设或实现的可能性不大的情况):谓语主要形式如下(be多用were这个形式):从句主句过去式would+动词原形If I were you,I wouldn’ｔl ose heart.How nice it would be if you could stay a bit longer.b)表示过去情况的虚拟条件句(与事实完全相反的假设情况),谓语主要形式如下:从句主句had+过去分词would have+过去分词She would have come if we had invited her.taken your advice,I would havemade a bad mistake,If I hadn’ｔYou wouldn’ｔh ave caught cold if you had put on more clothes.2)有时候,条件从句表示的动作和主句表示的动作,发生的时间是不一致的(如一个是过去发生的,一个是现在发生的).这时,动词的形式要根据表示的时间来调整.这种句子可以称为错综时间条件句.If he had received six more votes,he would be our chairman now.got everything ready by now,we should be having a terrible time tomorrow.If we hadn’ｔ3)有时假设的情况并不以条件从句表示,而是通过一个介词短语来表示.Without music,the world would be a dull place.We could have done better under more favorable conditions.That would have been considered miraculous in the past.But for the storm,we should have arrived earlier.4)如果条件句从句中包含有were,had,should或could,有时可把if省略掉,并把were,had,should或could放在主语前面.Had we made adequatepreparation,we might have succeeded.Should there be a flood,what should we do?Were it not for

can safely depend on.The people(who/that)you were talking to were Swedes.There are some people here who I want you to meet.但在介词后只能用whom:This is the man to whom I

girl(who/that)I spoke to is my cousin.2)限制性定语从句如果修饰“物”,用关系代词that的时候较多,也有时用which..当这个代词在从句中是用作宾语时,在绝大多数情况下都是省略的,特别是口语中(尤其是当被。
