55、ing,everything,somebody,someone,anybody,anyone,nothing,nobody,no one,none,everybody,everyone.等。2)不定代词的功能与用法a.除every和no外不定代词既可用作名词,也可用作形容词。every和no在句中只能作定语。I have no idea about it.b.all都,指三者以上。all的主谓一致:all的单复数由它所修饰或指代的名词的单复数决定。All goes well.一切进展得很好。all通常不与可数名词单数连用,如:不说all the book,而说the whole book。但a

56、ll可与表时间的可数名词单数连用,如all day,all night,all the year;但习惯上不说all hour,all century。all还可以与一些特殊的单数名词连用,如all China,all the city,all my life,all the way3)both都,指两者。a.both与复数动词连用,但bothand可与单数名词连用。b.both,all都可作同位语,其位置在行为动词前,be动词之后。如果助动词或情态动词后面的实义动词省去,则位于助动词或情态动词之前。Who can speak Japanese?We both(all) can.4)neith

57、er两者都不a.neither作主语时,谓语动词用单数。b.作定语与单数名词连用,但neithernor用作并列连词,可与复数名词连用。其谓语采用就近原则。c.可用于下列句型,避免重复。She cant sing,neither(can) he.neither与nord.如前句是否定式从句,则主句用neither,而不用nor。If you dont do it,neither should I.如果你不干,我也不干。e.如后连续有几个否定句式,则用nor,不用neither。He cant sing,nor dance,nor skate.3.13none,few,some,any,one,

61、3.14代词比较辩异one,that和itone表示泛指,that和it表示特指。that与所指名词为同类,但不是同一个,而it与所指名词为同一个。I cant find my hat.I think I must buy one.(不定)我找不到我的帽子了。我想我该去买一顶。The hat you bought is bigger than that I bought.(同类但不同个)你买的那顶帽子比我买的大。I cant find my hat.I dont know where I put it.(同一物)我找不到我的帽子。我不知道我把它放在哪了。3.15one/another/theo

63、但不是全部时,也用others。3.16“the”的妙用He is one of the students who help me.He is the one of the students who helps me.他是帮我的学生之一。第一句定语从句与the students一致。第二句定语从句与the one一致。3.17anyone/any one;no one/none;every/each1anyone和any oneanyone仅指人,any one既可指人,也可指物。2no one和nonea)none后跟of短语,既可指人又可指物,而no one只单独使用,只指人。b)none

64、作主语,谓语动词用单,复数均可,而no one作主语谓语动词只能是单数。None of you could lift it.你们中没有人可举起它。-Did anyone call me up just now?-刚才有人打电话给我吗?-No one. -没有。3every和each1)every强调全体的概念,each强调个体概念。Every student in our school works hard.我们学校的学生都很用功。Each student may have one book.每个学生都可有一本书。2)every指三个以上的人或物(含三个),each指两个以上的人或物(含两个)

65、。3)every只作形容词,不可单独使用。each可作代词或形容词。Every student has to take one.Each boy has to take one.Each of the boys has to take one.4)every不可以作状语,each可作状语。5)every有反复重复的意思,如every two weeks等;each没有。6)every与not连用,表示部分否定;each和not连用表示全部否定。Every man is not honest.并非每个人都诚实。Each man is not honest.这儿每个人都不诚实。3.18both,e

66、ither,neither,all,any,none这些词都可用作代词或形容词。其位置都在be动词之后,行为动词之前或第一助动词之后。1)both(两者都),either(两者中任何一个),neither(两者都不)。以上词使用范围为两个人或物。Neither of the two boys is clever.两个男孩都不聪明。2)both,eitherboth与复数连用,either与单数连用。Both the boys are clever.两个男孩都很聪明。Either of the two boys is clever.两个男孩都很聪明。There are flowers on bo

67、th sides of the street.(两岸)There are flowers on either side of the street.(岸的两边)路边长满了野花。3)all(所有的,全部的人或物),any(任何一个),none(都不)。以上词使用范围为三者以上。All the flowers are gone.所有的花都谢了。I dont like any of the flowers.这些花我都不喜欢。I like none of the flowers.这些花我都不喜欢。注意:all与none用法一样。跟单数名词,用单数动词;跟复数名词,用复数动词。All of the st

68、udents are there.所有的学生都在那。All(of) the milk is there.所有的牛奶都在那。3.19many,muchMany,much都意为许多,many+可数名词,much+不可数名词。How many people are there at the meeting?How much time has we left?Many of the workers were at the meeting.Much of the time was spent on learning.3.20few,little,afew,alittle(a)few+可数名词,(a)li

70、.本句为although引导的让步状语从句,由句意知后句为否定含义,因此应用little表示几乎不。固定搭配:only a few(=few)not a few(=many)quite a few(=many)many a(=many)Many books were sold.Many a book was sold.卖出了许多书。4.形容词和副词4.1形容词及其用法形容词修饰名词,说明事物或人的性质或特征。通常,可将形容词分成性质形容词和叙述形容词两类,其位置不一定都放在名词前面。1)直接说明事物的性质或特征的形容词是性质形容词,它有级的变化,可以用程度副词修饰,在句中可作定语、表语和补语。

71、例如:hot热的。2)叙述形容词只能作表语,所以又称为表语形容词。这类形容词没有级的变化,也不可用程度副词修饰。大多数以a开头的形容词都属于这一类。例如:afraid害怕的。(错)He is an ill man.(对)The man is ill.(错)She is an afraid girl.(对)The girl is afraid.这类词还有:well,unwell,ill,faint,afraid,alike,alive,alone,asleep,awake等。3)形容词作定语修饰名词时,要放在名词的前边。但是如果形容词修饰以-thing为字尾的词语时,要放在这些词之后,例如:so

108、成一般疑问句,例如:Do you want to pass the CET?你想通过大学英语测试吗?Did you study German?你们学过德语吗?2)do+not构成否定句,例如:I do not want to be criticized.我不想挨批评。He doesnt like to study.他不想学习。In the past,many students did not know the importance of English.过去,好多学生不知道英语的重要性。3)构成否定祈使句,例如:Dont go there.不要去那里。Dont be so absent-min

109、ded.不要这么心不在焉。说明:构成否定祈使句只用do,不用did和does。4)放在动词原形前,加强该动词的语气,例如:Do come to my birthday party.一定来参加我的生日宴会。I did go there.我确实去那儿了。I do miss you.我确实想你。5)用于倒装句,例如:Never did I hear of such a thing.我从未听说过这样的事情。Only when we begin our college life do we realize the importance of English.只有在开始大学生活时我们才认识到英语的重要性。

110、说明:引导此类倒装句的副词有never,seldom,rarely,little,only,so,well等。6)用作代动词,例如:-Do you like Beijing?-你喜欢北京吗?-Yes,I do.-是的,喜欢。(do用作代动词,代替like Beijing.)He know show to drive a car,doesnt he?他知道如何开车,对吧?5.6助动词shall和will的用法shall和will作为助动词可以与动词原形一起构成一般将来时,例如:I shall study harder at English.我将更加努力地学习英语。He will go to Sh

111、anghai.他要去上海。说明:在过去的语法中,语法学家说shall用于第一人称,will只用于第二、第三人称。现在,尤其是在口语中,will常用于第一人称,但shall只用于第一人称,如用于第二、第三人称,就失去助动词的意义,已变为情态动词,试比较:He shall come.他必须来。(shall有命令的意味。)He will come.他要来。(will只与动词原形构成一般将来时。)5.7助动词should,would的用法1)should无词义,只是shall的过去形式,与动词原形构成过去将来时,只用于第一人称,例如:I telephoned him yesterday to ask

112、what I should do next week.我昨天给他打电话,问他我下周干什么。比较:What shall I do next week?I asked.我下周干什么?我问道。(可以说,shall变成间接引语时,变成了should。)2)would也无词义,是will的过去形式,与动词原形构成过去将来时,用于第二、第三人称,例如:He said he would come.他说他要来。比较:I will go,he said.他说:我要去那儿。变成间接引语,就成了:He said he would come.原来的will变成would,go变成了come.。5.8短语动词动词加小品

113、构成的起动词作用的短语叫短语动词(Phrasal Verb)。例如:Turn off the radio.把收音机关上。(turn off是短语动词)短语动词的构成基本有下列几种:1)动词+副词,如:black out;2)动词+介词,如:look into;3)动词+副词+介词,如:look forward to。构成短语动词的副词和介词都统称为小品词(Particle)。5.9非谓语动词在句子中充当除谓语以外的句子成分的动词形式叫做非谓语动词。非谓语动词分为三种形式:不定式,动名词,和分词(分词包括现在分词和过去分词)。1)不定式时态语态主动被动一般式to doto be done完成式t

169、he decided to write again.A.Not receivingB.Receiving notC.Not having receivedD.Having not received答案C.本题考查分词的时态与分词的否定式。根据题意判断,分词的动作(接信)发生在谓语动词的动作(决心再写信)之前,因此用分词的完成式。分词的否定式的构成为not+分词,故选C。该句可理解为:Because he had not received a reply,he decided to write again.9.8分词的语态1)通常,现在分词表示主动,过去分词表示被动,例如:He is the m

170、an giving you the money.(=who gave you)他就是给你钱的那个人。He is the man stopped by the car.(=who was stopped by)他就是那个被车拦住的人。2)不及物动词的过去分词表示动作已经发生gone,fallen,retired,grown-up,escaped,faded,returned例:a well-read person.一个读过许多书的人a much-travelled may一个去过许多地方的人a burnt-out match烧完了的火柴10.独立主格10.1独立主格(一):独立主格结构的构成:名

171、词(代词)+现在分词、过去分词;名词(代词)+形容词;名词(代词)+副词;名词(代词)+不定式;名词(代词)+介词短语构成。(二)独立主格结构的特点:1)独立主格结构的逻辑主语与句子的主语不同,它独立存在。2)名词或代词与后面的分词,形容词,副词,不定式,介词等是主谓关系。3)独立主格结构一般有逗号与主句分开。举例:The test finished,we began our holiday.=When the test was finished,we began our holiday.考试结束了,我们开始放假。The president assassinated,the whole cou

172、ntry was in deep sorrow.=After the president was assassinated,the whole country was in deep sorrow.总统被谋杀了,举国上下沉浸在悲哀之中。Weather permitting,we are going to visit you tomorrow.如果天气允许,我们明天去看你。This done,we went home.工作完成后,我们才回家。The meeting gone over,everyone tired to go home earlier.会议结束后,每个人都想早点回家。He cam

173、e into the room,his ears red with cold.他回到了房子里,耳朵冻坏了。He came out of the library,a large book under his arm.他夹着本厚书,走出了图书馆10.2With的复合结构作独立主格表伴随时,既可用分词的独立结构,也可用with的复合结构。with+名词(代词)+现在分词/过去分词/形容词/副词/不定式/介词短语举例:He stood there,his hand raised.=He stood there,with his hand raise.典型例题The murder was brought

174、 in,with his hands_behind his back。A.being tiedB.having tiedC.to be tiedD.tied答案D.with+名词(代词)+分词+介词短语结构。当分词表示伴随状况时,其主语常常用with来引导。由于本句中名词手与分词绑是被动关系,因此用过去分词,选D.注意:1)独立主格结构使用介词的问题:当介词是in时,其前后的两个名词均不加任何成分(如物主代词或冠词),也不用复数。但with的复合结构不受此限制A robber burst into the room,knife in hand.(hand前不能加his)。2)当表人体部位的词做

175、逻辑主语时,及物动词用现在分词,不及物动词用过去分词。He lay there,his teeth set,his hand clenched,his eyes looking straight up.典型例题:Weather_,well go out for a walk.A permittedB permittingC permitsD for permitting答案B.本题中没有连词,它不是复合句,也不是并列句。句中使用了逗号,且we小写,可知其不是两个简单句。能够这样使用的只有独立主格或with的复合结构。据此判断,本句中使用的是独立结构,其结构为:名词+分词。由于permit在这里

176、翻译为天气允许,表主动,应用现在分词,故选B。如果不会判断独立结构作状语的形式,不妨将句子改为条件句,例如本句改为If weather permits,well go out for a walk.然后将if去掉,再将谓语动词改为非谓语动词即可。11.动词的时态11.1一般现在时的用法1)经常性或习惯性的动作,常与表示频腮度的时间状语连用。时间状语:every,sometimes,at,on SundayI leave home for school at 7 every morning.2)客观真理,客观存在,科学事实。The earth moves around the sun.Shang

195、his letter for a month.(对)I havent received his letter for almost a month.11.12比较since和forSince用来说明动作起始时间,for用来说明动作延续时间长度。I have lived here for more than twenty years.I have lived here since I was born.My aunt has worked in a clinic since 1949.Some new oil fields have been opened up since 1976.I hav

197、式转化,很容易就能排除非延续动词在完成时中的误使。1)(对)Tom has studied Russian for three years.=Tom began to study Russian three years ago,and is still studying it now.2)(错)Harry has got married for six years.=Harry began to get married six years ago,and is still getting married now.显然,第二句不对,它应改为Harry got married six years

236、shall we/shant we?=Shall we have another try?b.Let us不包括说话者Let us have another try,will you/wont you?=Will you please let us have another try?否定结构:Lets not talk of that matter.Let us not talk of that matter.13.2感叹句结构感叹句通常有what,how引导,表示赞美、惊叹、喜悦、等感情。what修饰名词,how修饰形容词,副词或动词,感叹句结构主要有以下几种:掌握它的搭配,即掌握了感叹句的

237、重点。How+形容词+a+名词+陈述语序How+形容词或副词+ 陈述语序What+名词+陈述语序What+a+形容词+名词+ 陈述语序What+形容词+复数名词+ 陈述语序What+形容词+不可数名词+ 陈述语序How clever a boy he is!How lovely the baby is!What noise they are making!What a clever boy he is!What wonderful ideas(we have)!What cold weather it is!感叹句的省略形式为:What a clever boy(heis)!典型例题1)_fo

238、od youve cooked!A.How a niceB.What a niceC.How niceD.What nice答案D.由于How修饰形容词,副词;what修饰名词。且food为不可数名词,因此A,B排除。CHow+adj.后面不能再加名词,因此只有D正确,其句型为What+adj.+n.(不可数)2)_terrible weather weve been having these days!A.WhatB.What aC.HowD.How a答案A.weather为不可数名词,B,D排除。C为how+adj.后面不应有名词。只有A,符合句型What+形容词+不可数名词。3)-_I

239、 had!-You really suffered a lot.A.What a timeB.What timeC.How a timeD.how time答案A.感叹句分两类:1:What+n.+主谓部分2:How+adj./adv./v.+主谓部分。本题属第一种,但省略了bad,相对于What a bad time I had!这是个习惯用语。13.3强调句结构常考的强调句结构是it引导的句子。It is(was)被强调部分+that(who)+句子其他部分。此结构强调的成分仅限于主语,宾语和状语。It is from the sun that we get light and heat.

240、It was not until I had ready our letter that I understood the true state of affairs.典型例题1)It was last night_I see the comet.A.thetimeB.whenC.thatD.which答案C.强调句的结构是:It+be+强调部分+that(who)+主谓句。强调句的连词只有两个,that和who。当强调的部分是人,且为句子的主语时,才用who,其余用that。原句:My father did the experiment in the lab yesterday evenin

241、g.强调主语:It was my father who did the experiment in the lab yesterday evening.强调宾语:It was the experiment that my father did in the lab yesterday evening.强调时间:It was yesterday evening that my father did the experiment in the lab.(注意不用when)强调地点:It was in the lab that my father did the experiment yesterd

242、ay evening.2)It is ten years_Miss Green returned to Canada.A.thatB.whenC.sinceD.as答案C.考点是连词用法。本题易误选为A.that.其实本句不是强调句。若是,去掉Itbethat还应是一个完整的句子。而本句去掉It isthat,只剩下ten years Miss Green returned to Canada.不成句。因此本句不是强调句。It is/was+时间+since其中is has beenwas had been.13.4用助动词进行强调强调句还有一种类型,就是用助动词do(did,does)强调谓

243、语。She does like this horse.她的确喜欢这匹马。Please do take care of yourself.千万保重。13.5反意疑问句1)陈述部分的主语是I,疑问部分要用arent I.Im as tall as your sister,arent I?2)陈述部分的谓语是wish,疑问部分要用may+主语。I wish to have a word with you,may I?3)陈述部分用no,nothing,nobody,never,few,seldom,hardly,rarely,little等否定含义的词时,疑问部分用肯定含义。The Swede ma

248、is not the man who gave us a talk,is he?He said he wanted to visit Japan,didnt he?c.上述部分主句谓语是think,believe,expect,suppose,imagine等引导的定语从句,疑问部分与宾语从句相对应构成反意疑问句。Idont think he is bright,is he?We believe she can do it better,cant she?15)陈述部分主语是不定代词everybody,anyone,somebody,nobody,noone等,疑问部分常用复数they,有时也

249、用单数he。Everyone knows the answer,dont they?(does he?)Nobody knows about it,do they?(does he?)16)带情态动词dare或need的反意疑问句,疑问部分常用need(dare)+主语。We need not do it again,need we?He dare not say so,dare you?当dare,need为实义动词时,疑问部分用助动词do+主语。She doesnt dare to go home alone,does she?17)省去主语的祈使句的反意疑问句,疑问部分用will you

250、。Dont do that again,will you?Go with me,will you/wont you?注意:Lets开头的祈使句,后用shall we?Let us开头的祈使句,后用willyou?Lets go and listen to the music,shall we?Let us wait for you in the reading-room,will you?18)陈述部分是there be结构的,疑问部分用there省略主语代词。There is something wrong with your watch,isnt there?There will not

251、be any trouble,will there?19)否定前缀不能视为否定词,其反意疑问句仍用否定形式。It is impossible,isnt it?He is not unkind to his classmates,is he?20)must在表推测时,根据其推测的情况来确定反意疑问句。He must be there now,isnt he?It must be going to rain tomorrow,wont it?快速记忆表陈述部分的谓语 疑问部分Iarent IWish may+主语no,nothing,nobody,never,few,seldom,hardly,肯

254、句14.倒装14.1倒装句之全部倒装全部倒装是只将句子中的谓语动词全部置于主语之前。此结构通常只用与一般现在时和一般过去时。常见的结构有:1)here,there,now,then,thus等副词置于句首,谓语动词常用be,come,go,lie,run。There goes the bell.Then came the chairman.Here is your letter.2)表示运动方向的副词或地点状语置于句首,谓语表示运动的动词。Out rushed a missile from under the bomber.A head sat an old woman.注意:上述全部倒装的句

255、型结构的主语必须是名词,如果主语是人称代词则不能完全倒装。Here he comes.Away they went.14.2倒装句之部分倒装部分倒装是指将谓语的一部分如助动词或情态倒装至主语之前。如果句中的谓语没有助动词或情态动词,则需添加助动词do,does或did,并将其置于主语之前。1)句首为否定或半否定的词语,如no,not,never,seldom,little,hardly,at no time,in no way,not until等。Never have I seen such a performance.No where will you find the answer to

256、 this question.Not until the child fell asleep did the mother leave the room.当Not until引出主从复合句,主句倒装,从句不倒装。注意:如否定词不在句首不倒装。I have never seen such a performance.The mother didnt leave the room until the child fell asleep.典型例题1)Why cant I smoke here?At not ime_in the meeting-roomA.is smoking permittedB.

257、smoking is permittedC.smoking is it permittedD.does smoking permit答案A.这是一个倒装问题。当否定词语置于句首以表示强调时,其句中的主谓须用倒装结构。这些否定词包括no,little,hardly,seldom,never,not only,not until等。本题的正常语序是Smoking is permitted in the meeting-room at no time.2)Not until the early years of the 19th century_what heat is.A.man did know

258、B.man knowC.didnt man knowD.did man know答案D.看到Notuntil的句型,我们知道为一倒装句,答案在C,D中选一个。改写为正常语序为,Man did not know what he at is until the early years of the 19th.现在将not提前,后面就不能再用否定了,否则意思就变了。14.3以否定词开头作部分倒装如Not onlybut also,Hardly/Scarcelywhen,No soonerthanNot only did he refuse the gift,he also severely crit

259、icized the sender.Hardly had she gone out when a student came to visit her.No sooner had she gone out than a student came to visit her.典型例题No sooner_than it began to rain heavily.A.the game beganB.has the game begunC.did the game beginD.had the game begun答案D.以具有否定意义的副词放在句首时,一般采用倒装句(谓语前置)。这类表示否定意义的词有

260、never,seldom,scarcely,little,few,not,hardly,以及not onlybut(also),no soonerthan,hardlywhen scarcelywhen等等。注意:只有当Not onlybut also连接两个分句时,才在第一个分句用倒装结构。如果置于句首的Not onlybut also仅连接两个并列词语,不可用倒装结构。Not only you but also I am fond of music.14.4so,neither,nor作部分倒装表示也、也不的句子要部分倒装。Tom can speak French.So can Jack.

261、If you wont go,neither will I.典型例题-Do you know Jim quarrelled with his brother?-I dont know,_.A.nor dont I careB.nor do I careC.I dont care neitherD.I dont care also答案:B.nor为增补意思也不关心,因此句子应倒装。A错在用dont再次否定,C neither用法不对且缺乏连词。D缺乏连词。注意:当so引出的句子用以对上文内容加以证实或肯定时,不可用倒装结构。意为的确如此。Tom asked me to go to play fo

262、otball and so I did.-Its raining hard.-So it is.14.5only在句首要倒装的情况Only in this way,can you learn English well.Only after being asked three times did he come to the meeting.如果句子为主从复合句,则主句倒装,从句不倒装Only when he is seriously ill,does he ever stay in bed.14.6as,though引导的倒装句as/though引导的让步从句必须将表语或状语提前(形容词,副词

263、,分词,实义动词提前)。注意:1)句首名词不能带任何冠词。2)句首是实义动词,其他助动词放在主语后。如果实义动词有宾语和状语,随实义动词一起放在主语之前。Try hard as he will,he never seems able to do the works at is factorily.注意:让步状语从句中,有though,although时,后面的主句不能有but,但是though和yet可连用。14.7其他部分倒装1)sothat句型中的so位于句首时,需倒装。So frightened was he that he did not dare to move an inch.2)

264、在某些表示祝愿的句型中:May you all be happy.3)在虚拟语气条件句中从句谓语动词有were,had,should等词,可将if省略,把were,had,should移到主语之前,采取部分倒装。Were I you,I would try it again.典型例题:1)Not until the early years of the 19th century_what he at isA.man did knowB.man knewC.didnt man knowD.did man know答案为D.否定词Not在句首,要求用部分倒装的句子结构。2)Not until I

265、began to work_how much time I had wasted.A.didnt I realizeB.did I realizeC.I didnt realizeD.I realize答案为B。3)Do you know Tom bought a new car?I dont know,_.A.nor dont I careB.nor do I careC.I dont care neitherD.I dont care also解析:答案为B.句中的nor引出部分倒装结构,表示也不。由so,neither,nor引导的倒装句,表示前一情况的重复出现。其中,so用于肯定句,而

266、neither,nor用在否定句中。15.主谓一致主谓一致是指:1)语法形式上要一致,即单复数形式与谓语要一致。2)意义上要一致,即主语意义上的单复数要与谓语的单复数形式一致。3)就近原则,即谓语动词的单复形式取决于最靠近它的词语,一般来说,不可数名词用动词单数,可数名词复数用动词复数。There is much water in the thermos.但当不可数名词前有表示数量的复数名词时,谓语动词用复数形式。Ten thousand tons of coal were produced last year.15.1并列结构作主语时谓语用复数Reading and writing are

267、very important.注意:当主语由and连结时,如果它表示一个单一的概念,即指同一人或同一物时,谓语动词用单数,and此时连接的两个词前只有一个冠词。Their on and steel industry is very important to our life.典型例题The League secretary and monitor_asked to make a speech at the meeting.A.isB.wasC.areD.were答案B.注:先从时态上考虑。这是过去发生的事情应用过去时,先排除A.,C.。本题易误选D,因为The League secretary

268、 and monitor好象是两个人,但仔细辨别,monitor前没有the,在英语中,当一人兼数职时只在第一个职务前加定冠词。后面的职务用and相连。这样本题主语为一个人,所以应选B。15.2主谓一致中的靠近原则1)当there be句型的主语是一系列事物时,谓语应与最邻近的主语保持一致。There is a pen,a knife and several books on the desk.There are twenty boy-students and twenty-three girl-students in the class.2)当eitheror与neithernor,连接两个

269、主语时,谓语动词与最邻近的主语保持一致。如果句子是由here,there引导,而主语又不止一个时,谓语通常也和最邻近的主语一致。Either you or she is to go.Here is a pen,a few envelops and some paper for you.15.3谓语动词与前面的主语一致当主语后面跟有with,together with,like,except,but,no less than,as well as等词引起的短语时,谓语动词与前面的主语一致。The teacher together with some students is visiting th

270、e factory.He as well as I wants to go boating.15.4谓语需用单数1)代词each和由every,some,no,any等构成的复合代词作主语,或主语中含有each,every,谓语需用单数。Each of us has a tape-recorder.There is something wrong with my watch.2)当主语是一本书或一条格言时,谓语动词常用单数。The Arabian Night is a book known to lovers of English.是英语爱好者熟悉的一本好书。3)表示金钱,时间,价格或度量衡的

271、复合名词作主语时,通常把这些名词看作一个整体,谓语一般用单数。(用复数也可,意思不变。)Three weeks was allowed for making the necessary preparations.Ten yuan is enough.15.5指代意义决定谓语的单复数1)在代词what,which,who,none,some,any,more,most,all等词的单复数由其指代的词的单复数决定。All is right.(一切顺利。)All are present.(所有人都到齐了。)2)集体名词作主语时,谓语的数要根据主语的意思来决定。如family,audience,cre

272、w,crowd,class,company,committee等词后用复数形式时,意为这个集体中的各个成员,用单数时表示该个集体。His family isnt very large.他家不是一个大家庭。His family are music lovers.他的家人都是音乐爱好者。但集合名词people,police,cattle,poultry等在任何情况下都用复数形式。Are there any police around?3)有些名词,如variety,number,population,proportion,majority等有时看作单数,有时看作复数。A number of+名词复

273、数+复数动词。The number of+名词复数+单数动词。A number of books have lent out.The majority of the students like English.15.6与后接名词或代词保持一致1)用half of,part of,most of,a portion of等词引起主语时,动词通常与of后面的名词,代词保持一致。Most of his money is spent on books.Most of the students are taking an active part in sports.2)在一些短语,如manya或more

274、 than one所修饰的词作主语时,谓语动词多用单数形式。但由more thanof作主语时,动词应与其后的名词或代词保持一致。Many a person has read the novel.许多人都读过这本书。More than 60 percent of the students are from the city.百分之六十多的学生都来自这个城市。16.虚拟语气1)概念虚拟语气用来表示说话人的主观愿望或假想,所说的是一个条件,不一定是事实,或与事实相反。2)在条件句中的应用条件句可分为两类,一类为真实条件句,一类为非真实条件句。非真实条件句表示的是假设的或实际可能性不大的情况,故采用

275、虚拟语气。16.1真实条件句真实条件句用于陈述语气,假设的情况可能发生,其中if是如果的意思。时态关系句型:条件从句主句一般现在时shall/will+动词原形If he comes,he will bring his violin.典型例题The volleyball match will be put off if it_.A.will rainB.rainsC.rainedD.is rained答案B。真实条件句主句为将来时,从句用一般现在时。注意:1)在真实条件句中,主句不能用begoingto表示将来,该用shall,will.(错)If you leave now,you are

276、never going to regret it.(对)Ifyouleavenow,youwillneverregretit.2)表示真理时,主句谓语动词便不用shall(will)+动词原形,而直接用一般现在时的动词形式。16.2非真实条件句1)时态:可以表示过去,现在和将来的情况。它的基本特点是时态退后。a.同现在事实相反的假设。句型:条件从句主句一般过去时should(would)+动词原形If they were here,they would help you.b.表示于过去事实相反的假设。句型:条件从句主句过去完成时should(would) have+过去分词If she had

277、 worked harder,she would have succeeded.The rice would not have been burnt if you had been more careful.If my lawyer had been here last Saturday,he would have prevented me from going.If he had come yesterday,I should/would have told him about it.含义:He did not come yesterday,so I did not tell him abo

278、ut it.If he had not been ill and missed many classes,he would have made greater progress.含义:He was ill and missed many lessons,so he did not make greater progress.c.表示对将来的假想句型:条件从句主句一般过去时should+动词原形were+不定式would+动词原形should+动词原形If you succeeded,everything would be all right.If you should succeed,ever

279、ything would be all right.If you were to succeed,everything would be all right.16.3混合条件句主句与从句的动作发生在不同的时间,这时主,从句谓语动词的虚拟语气形式因时间不同而不同,这叫做混合条件句。If you had asked him yesterday,you would know what to do now.(从句与过去事实相反,主句与现在事实相反。)If it had rained last night(过去),it would be very cold today(现在).16.4虚拟条件句的倒装虚

280、拟条件句的从句部分如果含有were,should,或had,可将if省略,再把were,should或had移到从句句首,实行倒装。Were they here now,they could help us.=If they were here now,they could help us.Had you come earlier,you would have met him=If you had come earlier,you would have met him.Should it rain,the crops would be saved.=Were it to rain,the cr

281、ops would be saved.注意:在虚拟语气的从句中,动词be的过去时态一律用were,不用was,即在从句中be用were代替。If I were you,I would go to look for him.如果我是你,就会去找他。If he were here,everything would be all right.如果他在这儿,一切都会好的。典型例题_to do the work,I should do it some other day.A.If were IB.I wereC.Were ID.Was I答案C.在虚拟条件状语中如果有were,should,had这三个

282、词,通常将if省略,主语提前,变成were,should,had+主语的形式。但要注意,在虚拟条件状语从句中,省略连词的倒装形式的句首不能用动词的缩略形式。如我们可说Were I not to do.,而不能说Werent I to do.16.5特殊的虚拟语气词:should1)It is demanded/necessary/apity+that结构中的主语从句的谓语动词要用should加动词原形,should可省略。句型:(1)suggestedIt is(2)importantthat+(should)do(3)a pity(1)suggested,ordered,proposed,r

283、equired,demanded,requested,insisted;+(should)do(2)important,necessary,natural,strange,a pity,a shame,no wonder(3)It is suggested that we (should)hold a meeting next week.It is necessary that he(should) come to our meeting tomorrow.2)在宾语从句中的应用在表示命令、建议、要求等一类动词后面的从句中。order,suggest,propose,require,deman

284、d,request,insist,command,insist+(should)doI suggest that we(should) hold a meeting next week.He insisted that he(should) be sent there.注意:如suggest,insist不表示建议或坚持要某人做某事时,即它们用于其本意暗示、表明、坚持认为时,宾语从句用陈述语气。The guard at gate insisted that everybody obey the rules.判断改错:(错)You pale face suggests that you (sho

285、uld)be ill.(对)Your pale face suggests that you are ill.(错)I insisted that you (should)be wrong.(对)I insisted that you were wrong.3)在表语从句,同位语从句中的应用在suggestion,proposal,idea,plan,order,advice等名词后面的表语从句、同位语从句中要用虚拟语气,即(should)+动词原形。My idea is that we (should)get more people to attend the conference.I ma

286、ke a proposal that we (should)hold a meeting next week.16.6wish的用法1)用于wish后面的从句,表示与事实相反的情况,或表示将来不太可能实现的愿望。其宾语从句的动词形式为:真实状况wish后从句动作先于主句动词动作现在时过去时(be的过去式为were)从句动作与主句动作同时发生过去时过去完成时(had+过去分词)将来不大可能实现的愿望将来时would/could+动词原形I wish I were as tall as you.我希望和你一样高。He wished he hadnt said that.他希望他没讲那样的话。I w

287、ish it would rain tomorrow.我希望明天下雨就好了。2)Wish to do表达法。Wish sb/sth to doI wish to see the manager.=I want to see the manager.I wish the manager to be informed at once.(=I want the manager to be informed at once.)16.7比较if only与only ifonly if表示只有;if only则表示如果就好了。If only也可用于陈述语气。I wake up only if the al

288、arm clock rings.只有闹钟响了,我才会醒。If only the alarm clock had rung.当时闹钟响了,就好了。If only he comes early.但愿他早点回来。16.8It is(high) time thatIt is(high) time that后面的从句谓语动词要用过去式或用should加动词原形,但should不可省略。It is time that the children went to bed.It is high time that the children should go to bed.16.9need不必做和本不该做did

289、nt need to do表示:过去不必做某事,事实上也没做。.neednt have done表示:过去不必做某事,但事实上做了。John went to the station with the car to meet Mary,so she didnt need to walk back home.约翰开车去车站接玛丽,所以她不必步行回家了。John went to the station with the car to meet Mary,so she neednt have walked back home.约翰开车去车站接玛丽,所以她本不必步行回家了。(Mary步行回家,没有遇上J

290、ohn的车。)典型例题There was plenty of time.She_.A.mustnt have hurriedB.couldnt have hurriedC.must not hurryD.neednt have hurried答案D。neednt have done.意为本不必,即已经做了某事,而时实际上不必要。Mustnt have done用法不正确,对过去发生的事情进行否定性推断应为couldnt have done,不可能已经。must not do不可以(用于一般现在时)。17.名词性从句在句子中起名词作用的句子叫名词从句(NounClauses)。名词从句的功能相当

291、于名词词组,它在复合句中能担任主语、宾语、表语、同位语、介词宾语等,因此根据它在句中不同的语法功能,名词从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。17.1引导名词性从句的连接词引导名词性从句的连接词可分为三类:连接词:that,whether,if不充当从句的任何成分)连接代词:what,whatever,who,whoever,whom,whose,which.连接副词:when,where,how,why不可省略的连词:1.介词后的连词2.引导主语从句和同位语从句的连词不可省略。That she was chosen made us very happy.We heard

292、the news that our team had won.比较:whether与if均为是否的意思。但在下列情况下,whether不能被if取代:1.whether引导主语从句并在句首2.引导表语从句3.whether从句作介词宾语4.从句后有or notWhether he will come is not clear.大部分连接词引导的主语从句都可以置于句末,用it充当形式主语。It is not important who will go.It is still unknown which team will win the match.17.2名词性that-从句1)由从属连词th

293、at引导的从句叫做名词性that-从句。That只起连接主句和从句的作用,在从句中不担任任何成分,本身也没有词义。名词性that-从句在句中能充当主语、宾语、表语、同位语和形容词宾语,例如:主语:That he is still alive is sheer luck.他还活着全靠运气。宾语:John said that he was leaving for Londonon Wednesday.约翰说他星期三要到伦敦去。表语:The fact is that he has not been seen recently.事实是近来谁也没有见过他。同位语:The fact that he has

294、 not been seen recently disturbs everyone in his office.近来谁也没有见过他,这一事实令办公室所有的人不安。形容词宾语:I am glad that you are sat is fied with your job.你对工作满意我感到很高兴。2)That-从句作主语通常用it作先行词,而将that-从句置于句末,例如:It is quite clear that the whole project is doomed to failure.很清楚,整个计划注定要失败。Its a pity that you should have to l

295、eave.你非走不可真是件憾事。用it作形式主语的that-从句有以下四种不同的搭配关系:a.It+be+形容词+that-从句It is necessary that有必要It is important that重要的是It is obvious that很明显b.It+be+-ed分词+that-从句It is believed that人们相信It is known to all that从所周知It has been decided that 已决定c.It+be+名词+that-从句It is common knowledge that是常识It is a surprise that

296、令人惊奇的是It is a fact that事实是d.It+不及物动词+that-分句It appears that似乎It happens that碰巧It occurred to me that 我突然想起17.3名词性wh-从句1)由wh-词引导的名词从句叫做名词性wh-从句。Wh-词包括who,whom,.whose,whoever,what,whatever,which,whichever等连接代词和where,when,how,why等连接副词。Wh-从句的语法功能除了和that-从句一样外,还可充当介词宾语、宾语补语和间接宾语等,例如:主语:How the book will

297、sell depends on its author.书销售如何取决于作者本人。直接宾语:In ones own home one can do what one likes.在自己家里可以随心所欲。间接宾语:The club will give whoever wins a prize.俱乐部将给得胜者设奖。表语:My question is who will take over president of the Foundation.我的问题是谁将接任该基金会主席职位。宾语补足语:She will name him what ever she wants to.她高兴给他起什么名字就取什么

298、名字。同位语:I have no idea when he will return.我不知道他什么时候回来。形容词宾语:Im not sure why she refused their invitation.我尚不能肯定她为什么拒绝他们的邀请。介词宾语:That depends on where we shall go.那取决于我们去哪儿。2)Wh-从句作主语也常用先行词it做形式主语,而将wh-从句置于句末,例如:It is not yet decided who will do that job.还没决定谁做这项工作。It remains unknown when they are go

299、ing to get married.他们何时结婚依然不明。17.4if,whether引导的名词从句1)yes-no型疑问从句从属连词if,whether引导的名词从句是由一般疑问句或选择疑问转化而来的,因此也分别被称为yes-no型疑问句从句和选择型疑问从句,其功能和wh-从句的功能相同,例如:主语:Whether the plan is feasible remains to be proved.这一计划是否可行还有等证实。宾语:Let us know whether/if you can finish the article before Friday.请让我们知道你是否能在星期五以前

300、把文章写完。表语:The point is whether we should lend him the money.问题在于我们是否应该借钱给他。同位语:They are investigating the question whether the man is trust worthy.他们调查他是否值得信赖。形容词宾语:Shes doubtful whether we shall be able to come.她怀疑我们是否能够前来。介词宾语:I worry about whether he can pass through the crisis of his illness.我担心他

301、是否能度过疾病的危险期。2)选择性疑问从句选择性疑问从句由关联词if/whetheror或whetheornot构成,例如:Please tell me whether/if they are Swedish or Danish.请告诉我他们是瑞典人还是丹麦人。I dont care whether you like the plan or not.我不在乎你是否喜欢该计划。17.5否定转移1)将think,believe,suppose,expect,fancy,imagine等动词后面宾语从句的否定词转移到主句中,即主句的谓语动词用否定式,而从句的谓语动词用肯定式。I dont think

302、 I know you.我想我并不认识你。I dont believe he will come.我相信他不回来。注意:若谓语动词为hope,宾语从句中的否定词不能转移。I hope you werent ill.我想你没有生病吧。2)将seem,appear等后的从句的否定转移到前面。It doesnt seem that they know where to go.看来他们不知道往哪去。It doesnt appear that well have a sunnyday tomorrow.看来我们明天不会碰上好天气。3)有时将动名词,介词短语或整个从句的否定转变为对谓语动词的否定。I do

303、nt remember having ever seen such a man.我记得从未见过这样一个人。(not否定动名词短语having)Its not a place where any one would expect to see strange characters on the street.在这里,人们不会想到在街上会碰上陌生的人。(anyone作主语,从句中的谓语动词不能用否定形式。)4)有时状语或状语从句中否定可以转移到谓语动词前。The ant is not gathering this for itself alone.(否定状语)蚂蚁不只是为自己采食。He was n

304、ot ready to believe something just because Aristotle said so.(否定because状语)他并不因亚里斯多德说过如何如何,就轻信此事。She had not been married many weeks when that mans younger brother saw her and was struck by her beauty.(否定状语many weeks)她结婚还不到几个月,这个人的弟弟就看见她了,并对她的美貌着了迷。18.定语从句定语从句(Attributive Clauses)在句中做定语,修饰一个名词或代词,被修饰

305、的名词,词组或代词即先行词。定语从句通常出现在先行词之后,由关系词(关系代词或关系副词)引出。关系代词有:who,whom,whose,that,which等。关系副词有:when,where,why等。18.1关系代词引导的定语从句关系代词所代替的先行词是人或物的名词或代词,并在句中充当主语、宾语、定语等成分。关系代词在定语从句中作主语时,从句谓语动词的人称和数要和先行词保持一致。1)who,whom,that这些词代替的先行词是人的名词或代词,在从句中所起作用如下:Is he the man who/that wants to see you?他就是你想见的人吗?(who/that在从句中

306、作主语)He is the man whom/that I saw yesterday.他就是我昨天见的那个人。(whom/that在从句中作宾语)2)Whose用来指人或物,(只用作定语,若指物,它还可以同of which互换),例如:They rushed over to help the man whose car had broken down.那人车坏了,大家都跑过去帮忙。Pleasepassmethebookwhose(ofwhich)coverisgreen.请递给我那本绿皮的书。3)which,that它们所代替的先行词是事物的名词或代词,在从句中可作主语、宾语等,例如:A p

307、rosperity which/that had never been seen before appears in the countryside.农村出现了前所未有的繁荣。(which/that在句中作宾语)The package(which/that)you are carrying is about to come unwrapped.你拿的包快散了。(which/that在句中作宾语)18.2关系副词引导的定语从句关系副词可代替的先行词是时间、地点或理由的名词,在从句中作状语。1)when,where,why关系副词when,where,why的含义相当于介词+which结构,因此常

308、常和介词+which结构交替使用,例如:There are occasions when(on which)one must yield.任何人都有不得不屈服的时候。Beijing is the place where(in which) I was born.北京是我的出生地。Is this the reason why(for which) he refused our offer?这就是他拒绝我们帮助他的理由吗?2)that代替关系副词that可以用于表示时间、地点、方式、理由的名词后取代when,where,why和介词+which引导的定语从句,在口语中that常被省略,例如:His

309、 father died they ear(that/when/in which)he was born.他父亲在他出生那年逝世了。He is unlikely to find the place(that/where/in which) he lived forty years ago.他不大可能找到他四十年前居住过的地方。18.3判断关系代词与关系副词方法一:用关系代词,还是关系副词完全取决于从句中的谓语动词。及物动词后面无宾语,就必须要求用关系代词;而不及物动词则要求用关系副词。例如:This is the mountain village where I stayed last yea

310、r.Ill never forget the days when I worked together with you.判断改错(注:先显示题,再显示答案,横线;用不同的颜色表示出。)(错)This is the mountain village where I visited last year.(错)I will never forget the days when I spent in the countryside.(对)This is the mountain village(which) I visited last year.(对)Ill never forget the day

311、s(which) I spent in the countryside.习惯上总把表地点或时间的名词与关系副词where,when联系在一起。此两题错在关系词的误用上。方法二:准确判断先行词在定语从句中的成分(主、谓、宾、定、状),也能正确选择出关系代词/关系副词。例1.Is this museum_you visited a few days age?A.whereB.thatC.onwhichD.theone例2.Is this the museum_the exhibition was held.A.whereB.thatC.on whichD.the one答案:例1D,例2A例1变为

312、肯定句:This museum is_you visited a few days ago.例2变为肯定句:This is the museum_the exhibition was held.在句1中,所缺部分为宾语,而where,that,onw hich都不能起到宾语的作用,只有the one既做了主句的表语,又可做从句的宾语,可以省略关系代词,所以应选D。而句2中,主、谓、宾俱全,从句部分为句子的状语表地点,既可用副词where,又因in the museum词组,可用介词in+which引导地点状语。而此题中,介词on用的不对,所以选A。关系词的选择依据在从句中所做的成分,先行词在从

313、句中做主、定、宾语时,选择关系代词(who,whom,that,which,whose);先行词在从句中做状语时,应选择关系副词(where地点状语,when时间状语,why原因状语)。18.4限制性和非限制性定语从句1)定语从句有限制性和非限制性两种。限制性定语从句是先行词不可缺少的部分,去掉它主句意思往往不明确;非限制性定语从句是先行词的附加说明,去掉了也不会影响主句的意思,它与主句之间通常用逗号分开,例如:This is the house which we bought last month.这是我们上个月买的那幢房子。(限制性)The house,which we bought la

314、st month,is very nice.这幢房子很漂亮,是我们上个月买的。(非限制性)2)当先行词是专有名词或物主代词和指示代词所修饰时,其后的定语从句通常是非限制性的,例如:Charles Smith,who was my former teacher,retired last year.查理史密斯去年退休了,他曾经是我的老师。My house,which I bought last year,has got a lovely garden.我去年买的的那幢房子带着个漂亮的花园。This novel,which I have read three times,is very touchi

315、ng.这本小说很动人,我已经读了三遍。3)非限制性定语从句还能将整个主句作为先行词,对其进行修饰,这时从句谓语动词要用第三人称单数,例如:He seems not to have grasped what I meant,which greatly up sets me.他似乎没抓住我的意思,这使我心烦。Liquid water changes to vapor,which is called evaporation.液态水变为蒸汽,这就叫做蒸发。说明:关系代词that和关系副词why不能引导非限制性定语从句。18.5介词+关系词1)介词后面的关系词不能省略。2)that前不能有介词。3)某些

316、在从句中充当时间,地点或原因状语的介词+关系词结构可以同关系副词when和where互换。This is the house in which I lived two years ago.This is the house where I lived two years ago.Do you remember the day on which you joined our club?Do you remember the day when you joined our club?18.6as,which非限定性定语从句由as,which引导的非限定性定语从句,as和which可代整个主句,相当

317、于and this或and that。As一般放在句首,which在句中。As we know,smoking is harmful to ones health.The sun heats the earth,which is very important to us.典型例题1)Alice received an invitation from her boss,_came as a surprise.A.itB.thatC.whichD.he答案C.此为非限定性从句,不能用that修饰,而用which.,it和he都使后句成为句子,两个独立的句子不能单以逗号连接。况且选he句意不通。2)

318、The weather turned out to be very good,_was more than we could expect.A.whatB.whichC.thatD.it答案B。which可代替句子,用于非限定性定语从句,而what不可。That不能用于非限定性定语从句,it不为连词,使由逗号连接的两个句子并在一起在英语语法上行不通。3)It rained hard yesterday,_prevented me from going to the park.A.thatB.whichC.asD.it答案B.as和which在引导非限制性定语从句时,这两个关系代词都指主句所表达

319、的整个意思,且在定语从句中都可以作主语和宾语。但不同之处主要有两点:(1)as引导的定语从句可置于句首,而which不可。(2)as代表前面的整个主句并在从句中作主语时,从句中的谓语必须是系动词;若为行为动词,则从句中的关系代词只能用which.。在本题中,prevent由于是行为动词,所以正确选项应为B。As的用法例1.the sameas;suchas中的as是一种固定结构,和一样。I have got into the same trouble as he(has).例2.as可引导非限制性从句,常带有正如。As we know,smoking is harmful to ones he

320、alth.As is know,smoking is harmful to ones health.As是关系代词。例1中的as作know的宾语;例2中,它充当从句的主语,谓语动词know要用被动式。18.7先行词和关系词二合一1)Whoever spits in public will be punished here.(Whoever可以用anyone who代替)2)The parents will use what they have to send their son to technical school.(what可以用all that代替)18.8what/whatever;t

321、hat/what;who/whoever1)what=the thing which;whatever=anythingWhat you want has been sent here.Whatever you want makes no difference to me.2)who=thepersonthatwhoever=anyone who(错)Who breaks the law will be punished.(错)Whoever robbed the bank is not clear.(对)Whoever breaks the law will be punished.(对)W

322、ho robbed the bank is not clear.3)that和what当that引导定语从句时,通常用作关系代词,而引导名词性从句时,是个不充当任何成分的连接词。宾语从句和表语从句中的that常可省略。What只能引导名词性从句,用作连接代词,作从句的具体成分,且不能省略。I think(that) you will like the stamps.What we need is more practice.18.9关系代词that的用法1)不用that的情况a)在引导非限定性定语从句时。(错)The tree,that is four hundred years old,is

323、 very famous here.b)介词后不能用。We depend on the land from which we get our food.We depend on the land that/which we get our food from.2)只能用that作为定语从句的关系代词的情况a)在there be句型中,只用that,不用which。b)在不定代词,如:anything,nothing,the one,all,much,few,any,little等作先行词时,只用that,不用which。c)先行词有the only,the very修饰时,只用that。d)先

324、行词为序数词、数词、形容词最高级时,只用that。.e)先行词既有人,又有物时。举例:All that is needed is a supply of oil.所需的只是供油问题。Finally,the thief handed everything that he had stolen to the police.那贼最终把偷的全部东西交给了警察。19.状语从句19.1地点状语从句地点状语从句通常由where,wherever引导。Where I live there are plenty of trees.我住的地方树很多。Wherever I am I will be thinking

325、 of you.不管我在哪里我都会想到你。19.2方式状语从句方式状语从句通常由as,(just)asso,as if,as though引导。1)as,(just)asso引导的方式状语从句通常位于主句后,但在(just)asso结构中位于句首,这时as从句带有比喻的含义,意思是正如,就像,多用于正式文体,例如:Always do to the others as you would be done by.你希望人家怎样待你,你就要怎样待人。As water is to fish,so air is to man.我们离不开空气,犹如鱼儿离不开水。Just as we sweep our r

326、ooms,so we should sweep backward ideas from our minds.正如打扫房屋一样,我们也要扫除我们头脑中落后的东西。2)as if,as though两者的意义和用法相同,引出的状语从句谓语多用虚拟语气,表示与事实相反,有时也用陈述语气,表示所说情况是事实或实现的可能性较大。汉译常作仿佛似的,好像似的,例如:They completely ignore these facts as if(as though)they never existed.他们完全忽略了这些事实,就仿佛它不存在似的。(与事实相反,谓语用虚拟语气。)He looks as if(

327、as though)he had been hit by lighting.他那样子就像被雷击了似的。(与事实相反,谓语用虚拟语气。)It looks as if the weather may pick up very soon.看来天气很快就会好起来。(实现的可能性较大,谓语用陈述语气。)说明:as if/as though也可以引导一个分词短语、不定式短语或无动词短语,例如:He stared at me as if seeing me for first time.他目不转睛地看着我,就像第一次看见我似的。He cleared his throat as if to say somet

328、hing.他清了清嗓子,像要说什么似的。The waves dashed on the rocks as if in anger.波涛冲击着岩石,好像很愤怒。19.3原因状语从句比较:because,since,as和for1)because语势最强,用来说明人所不知的原因,回答why提出的问题。当原因是显而易见的或已为人们所知,就用as或since。I didnt go,because I was afraid.Since/As the weather is so bad,we have to dela your journey.2)由because引导的从句如果放在句末,且前面有逗号,则可

329、以用for来代替。但如果不是说明直接原因,而是多种情况加以推断,就只能用for。He is absent today,because/for he is ill.He must be ill,for he is absent today.19.4目的状语从句表示目的状语的从句可以由that,so that,in order that,lest,for fear that,in case等词引导,例如:You must speak louder so that/in order that you can be heard by all.He wrote the name down for fea

330、r that(lest) he should forget it.Better take more clothes in case the weather is cold.19.5结果状语从句结果状语从句常由sothat或suchthat引导,掌握这两个句型,首先要了解so和such与其后的词的搭配规律。比较:so和such其规律由so与such的不同词性决定。such是形容词,修饰名词或名词词组,so是副词,只能修饰形容词或副词。so还可与表示数量的形容词many,few,much,little连用,形成固定搭配。so foolishsuch a foolso nice a flowersu

331、ch a nice flowerso many/few flowers such nice flowersso much/little money. such rapid progressso many peoplesuch a lot of people(so many已成固定搭配,a lot of虽相当于many,但a lot of为名词性的,只能用such搭配。)sothat与suchthat之间的转换既为so与such之间的转换。The boy is so young that he cant go to school.He is such a young boy that he ca

332、nt go to school19.6条件状语从句连接词主要有if,unless,as/so long as,on condition that等。if引导的条件句有真实条件句和非真实条件句两种。非真实条件句已在虚拟语气中阐述。unless=if not.Lets go out for a walk unless you are too tired.If you are not too tied,lets go out for a walk.典型例题You will be late_you leave immediately.A.unlessB.untilC.ifD.or答案A。句意:除非你立

333、即走,否则你就回迟到的。可转化为If you leave immediately,you will be late.B、D句意不对,or表转折,句子如为You leave immediately or you will be late.19.7让步状语从句though,although注意:当有though,although时,后面的从句不能有but,但是though和yet可连用Although its raining,they are still working in the field.虽然在下雨,但他们仍在地里干活。He is very old,but he still works v

334、ery hard.虽然他很老,但仍然努力地工作。Though the sore be healed,yet a scar may remain.伤口虽愈合,但伤疤留下了。(谚语)典型例题1)_she is young,she knows quite a lot.A.WhenB.HoweverC.AlthoughD.Unless答案:C。意为虽然她很年轻,却知道许多。2)as,though引导的倒装句as/though引导的让步从句必须表语或状语提前(形容词、副词、分词、实义动词提前)。Child as/though he was,he knew what was the right thing

335、 to do.=Though he was a small child,he knew what was the right thing to do.注意:a.句首名词不能带任何冠词。b.句首是实义动词,其他助动词放在主语后。如果实义动词有宾语和状语,随实义动词一起放在主语之前。Try hard as he will,he never seems able to do the works at is factorily.=Though he tries hard,he never seems虽然他尽了努力,但他的工作总做的不尽人意。3)ever if,even though.即使Well ma

336、ke a trip even though the weather is bad.4)whetheror-不管都Whether you believe it or not,it is true.5)no matter+疑问词或疑问词+后缀everNo matter what happened,he would not mind.What ever happened,he would not mind.替换:no matter what=whateverno matter who=whoeverno matter when=wheneverno matter where=whereverno m

337、atter which=whicheverno matter how=however注意:no matter不能引导主语从句和宾语从句。(错)No matter what you say is of no use now.(对)Whatever you say is of no use now.你现在说什么也没用了。(Whatever you say是主语从句)(错)Prisoners have to eat no matter what theyre given.(对)Prisoners have to eat what ever theyre given.囚犯们只能给什么吃什么。19.8比

338、较while,when,as1)as,when引导短暂性动作的动词。Just as/Just when/When I stopped my car,a man came up to me.2)当从句的动作发生于主句动作之前,只能用when引导这个从句,不可用as或while。When you have finished your work,you may have a rest.3)从句表示随时间推移连词能用as,不用when或while。As the day went on,the weather got worse.日子一天天过去,天气越变越坏。19.9比较until和till此两个连词意

339、义相同。肯定形式表示的意思是做某事直至某时,动词必须是延续性的。否定形式表达的意思是直至某时才做某事。动词为延续性或非延续性都可以。正确使用这两个连词的关键之一就在于判断句中的动词该用肯定式还是否定式。肯定句:I slept until midnight.我一直睡到半夜时醒了。Wait till I call you.等着我叫你。(在肯定句中可用before代替Lets get in the wheat before the sun sets.)否定句:She didnt arrive until 6 oclock.她直到6点才到。Dont get off the bus until it h

340、as stopped.公共汽车停稳后再下车。I didnt manage to do it until you had explained how.直到你教我后,我才会做。1)Until可用于句首,而till通常不用于句首。Until you told me,I had heard nothing of what happened.直到你告诉我以前,出了什么事我一点也不知道。2)Until when疑问句中,until要放在句首。-Until when are you staying?你呆到什么时候?-Until next Monday.呆到下周一。注意:否定句可用另外两种句式表示。(1)No

341、t until在句首,主句用倒装。Not until the early years of the 19th century did man know what heat is.直到19世纪初,人类才知道热能是什么。Not until I began to work did I realize how much time I had wasted.直到我开始工作,我才认识到了我已蹉跎了几多岁月。(2)It is not untilthat19.10表示一就的结构hardly/scarcelywhen/before,no soonerthan和as soon as都可以表示一就的意思,例:I h

342、ad hardly/scarcely got home when it began to rain.I had no sooner got home than it began to rain.As soon as I got home,it began to rain.注意:如果hardly,scarcely或no sooner置于句首,句子必须用倒装结构:Hardly/Scarcely had I got home when it began to rain.No sooner had I got home than it began to rain.20.连词连词是一种虚词,它不能独立担

343、任句子成分而只起连接词与词,短语与短语以及句与句的作用。连词主要可分为两类:并列连词和从属连词。并列连词用来连接平行的词、词组和分句。如:and,but,or,nor,so,therefore,yet,however,for,hence,as well as,bothand,not onlybut also,eitheror,neithernor,(and)then等等。20.1并列连词与并列结构并列连词引导两个并列的句子。1)and与or判断改错:(错)They sat down and talk about something.(错)They started to dance and sa

344、ng.(错)I saw two men sitting behind and whisper there.(对)They sat down and talked about something.(对)They started to dance and sing.(对)I saw two men sitting behind and whispering there.解析:第一句:and连接两个并列的谓语,所以talk应改为talked。第二句:and连接两个并列的动词不定式,第二个不定式往往省略to,因此sang应改为sing。第三句:and连接感观动词saw后面的用作的宾补的两个并列分词结构

345、,因此whisper应改为whispering。注意:and还可以和祈使句或名词词组连用表示条件。(or也有此用法)Make up your mind,and youll get the chance.=If you make up your mind,youll get the chance.One more effort,and youll succeed.=If you make one more effort,youll succeed.2)bothand两者都She plays (both)the piano and the guitar.3)not onlybut(also),as

346、 well as不但而且)She plays not only the piano,but(also) the guitar.注意:not onlybut also关联两个分句时,一个分句因有否定词not而必须倒装。Not only does he like reading stories,but also he can even write some.4)neithenor意思为既不也不谓语动词采用就近原则,与nor后的词保持一致。Neither you nor he is to blame.20.2比较and和or1)并列结构中,or通常用于否定句,and用于肯定句。2)但有时and也可用

347、于否定句。请注意其不同特点:There is no air or water in the moon.There is no air and no water on the moon.在否定中并列结构用or连接,但含有两个否定词的句子实际被看作是肯定结构,因此要用and。典型例题-I dont like chicken_fish.-I dont like chicken,_I like fish very much.A.and;andB.and;butC.or;butD.or;and答案C。否定句中表并列用or,but表转折。判断改错:(错)We will die without air an

348、d water.(错)We cant live without air or water.(对)We will die without air or water.(对)We cant live without air and water.20.3表示选择的并列结构1)or意思为否则。I must work hard,or Ill fail in the exam.2)eitheror意思为或者或者。注意谓语动词采用就近原则。Either you or I am right.20.4表示转折或对比1)but表示转折,while表示对比。Some people love cats,while ot

349、hers hate them.典型例题-Would you like to come to dinner tonight?-Id like to,_Im too busy.A.andB.soC.asD.but答案D。but与前面形成转折,符合语意。而表并列的and,结果的so,原因的as都不符合句意。2)notbut意思为不是而是not和but后面的用词要遵循一致原则。They were not the bones of ananimal,but(the bones)of a human being.20.5表原因关系1)for判断改错:(错)For he is ill,he is absen

350、t today.(对)He is absent today,for he is ill.for是并列连词,不能置于含两个并列分句的句子的句首,只能将其放在两个分句中间。2)so,there foreHe hurt his leg,so he couldnt play in the game.注意:a.两个并列连词不能连用,但therefore,then,yet.可以和并列连词连用。You can watch TV,and or you can go to bed.He hurt his leg,and so/and therefore he couldnt play in the game.b

351、.althoughyet,但although不与but连用。(错)Although he was weak,but he tried his best to do the work.(对)Although he was weak,yet he tried his best to do the work.20.6比较so和such其规律由so与such的不同词性决定。such是形容词,修饰名词或名词词组,so是副词,只能修饰形容词或副词。so还可与表示数量的形容词many,few,much,little连用,形成固定搭配。so+adj.such+a(n)+n.so+adj.+a(n)+n. su

352、ch+n.(pl.)so+adj.+n.(pl.) such+n.(pl.)so+adj.+n.不可数 such+n.不可数so foolish such a foolso nice a flower such a nice flowerso many/few flowerssuch nice flowersso much/little money.such rapid progressso many people such a lot of peopleso many已成固定搭配,a lot of虽相当于many,但a lot of为名词性的,只能用such搭配。sothat与suchtha

353、t之间的转换既为so与such之间的转换。21.情态动词21.1情态动词的语法特征1)情态动词不能表示正在发生或已经发生的事情,只表示期待或估计某事的发生。2)情态动词除ought和have外,后面只能接不带to的不定式。3)情态动词没有人称,数的变化,即情态动词第三人称单数不加-s。4)情态动词没有非谓语形式,即没有不定式,分词,等形式。21.1情态动词的语法特征1)情态动词不能表示正在发生或已经发生的事情,只表示期待或估计某事的发生。2)情态动词除ought和have外,后面只能接不带to的不定式。3)情态动词没有人称,数的变化,即情态动词第三人称单数不加-s。4)情态动词没有非谓语形式,

357、so I had to call the doctor in the middle of the night.我弟弟病得很厉害,我只得半夜里把医生请来。(客观上需要做这件事)He said that they must work hard.他说他们必须努力工作。(主观上要做这件事)2)haveto有人称、数、时态的变化,而must只有一种形式。但must可用于间接引语中表示过去的必要或义务。He had to look after his sister yesterday.3)在否定结构中:dont have to 表示不必,mustnt 表示禁止。You dont have to tell

362、 found his car,for he came to work by bus this morning.迈克一定还没有找回他的车,因为早上他是坐公共汽车来上班的。注意:could,might表示推测时不表示时态,其推测的程度不如can,may。21.7情态动词+have+过去分词1)may(might)have+done sth,can(could)have+done sth表示过去,推测过去时间里可能发生的事情。Philip may(might) have been hurt seriously in the car accident.Philip can(could) have be

363、en hurt seriously in the car accident.2)must have+done sth,对过去时间里可能发生的事情的推测,语气较强,具有肯定,谅必的意思。-Linda has gone to work,but her bicycle is still here.-She must have gone by bus.3)ought to have done sth,should have done sth本应该做某事,而事实上并没有做。否定句表示不该做某事而做了。You ought to(should) have been more careful in this

365、1.8should和ought toshould和ought to都为应该的意思,可用于各种人称。-Ought he to go?-Yes.I think he ought to.表示要求,命令时,语气由should(应该)、had better最好)、must(必须)渐强。21.9had better表示最好had better相当于一个助动词,它只有一种形式,它后面要跟动词原形。had better do sthhad better not do sthIt is pretty cold.Youd better put on my coat.Shed better not play wit

366、h the dog.had better have done sth表示与事实相反的结果,意为本来最好。You had better have come earlier.21.10would rather表示宁愿would rather dowould rather not dowould ratherthan宁愿而不愿。还有would sooner,had rather,had sooner都表示宁愿、宁可的意思。If I have a choice,I had sooner not continue my studies at this school.I would rather stay

367、 here than go home.=I would stay here rather than go home.典型例题-Shall we go skating or stay at home?-Which_do?A.do you ratherB.would you ratherC.will you ratherD.should you rather答案B。本题考查情态动词rather的用法,would rather+do sth意为宁愿,本题为疑问句,would提前,所以选B。21.11will和would注意:1)would like;Would like to do=want to想

368、要,为固定搭配。Would you like to go with me?2)Will you?Would you like?表示肯定含义的请求劝说时,疑问句中一般用some,而不是any。Would you like some cake?3)否定结构中用will,一般不用would,wont you是一种委婉语气。Wont you sit down?21.12情态动词的回答方式问句 肯定回答 否定回答Need you?Yes,I need.No,I needntMust you?Yes,I must.No,I needntNo,I dont have to.典型例题1)-Could I bo

369、rrow your dictionary?-Yes,of course,you_.A.mightB.willC.canD.should答案C.could表示委婉的语气,并不为时态。答语中of course,表示肯定的语气,允许某人做某事时,用can和may来表达,不能用could或might。复习:will与you连用,用来提出要求或下命令。should与you连用,用来提出劝告。2)-Shall I tell John about it?-No,you_.Ive told him already.A.needntB.wouldntC.mustntD.shouldnt答案A。neednt不必,

371、们的疑问,否定形式应予以注意:Do they have to pay their bill before the end of the month?She didnt use to play tennis before she was fourteen.You ought not to have told her all about it.Ought he to see a heart specialist at once?ought to本身作为情态动词使用。其他的词作为实义动词使用,变疑问,否定时,须有do等助动词协助。典型例题Tom ought not to_me your secret

372、,but he meant no harm.A.have toldB.tellC.be tellingD.having told答案A。由于后句为过去时,告诉秘密的动作又发生在其前因,此地应用过去完成时,但它在情态动词ought to后,所以用have。21.14比较need和dare这两词既可做实义动词用,又可做情态动词用。作为情态动词,两者都只能用于疑问句,否定句和条件句。need作实义动词时后面的不定式必须带to,而dare作实义动词用时,后面的to时常可以被省略。1)实义动词:need(需要,要求)need+n./to do sth2)情态动词:need,只用原形need后加do,否定形式为need not。Need you go yet?Yes,I must./No,I neednt.3)need的被动含义:need,want,require,worth(形容词)后面接doing也可以表示被动:need doing=need to be done
