语法讲解:名词性从句

俗话说,磨刀不误砍柴工。作为高中教师就要精心准备好合适的教案。教案可以让学生更好的吸收课堂上所讲的知识点,帮助高中教师提高自己的教学质量。你知道如何去写好一份优秀的高中教案呢?小编特地为大家精心收集和整理了“语法讲解:名词性从句”,仅供参考,大家一起来看看吧。

语法讲解:名词性从句
名词性从句相当于名词,可分别作主句的主语、表语、宾语和同位语。因此,名词性从句可分为主语从句、表语从句、宾语从句和同位从句。
一、引导名词性从句的连接词
1.连接代词:who,whose,whom,what,which.有词义,在从句中担任成分,如主语、表语、宾语、或定语等。
2.连接副词:when,where,why,how.有词义,在从句中担任成分,作状语。
3.连接词:that,whether,if,asif.that无词义,在从句中不担任成分,有时可省略;if(whether),asif虽有词义,但在从句中不担任成分。
注意:连接代词与连接副词在句中不再是疑问句,因而从句中谓语不用疑问式。连接代词与连接副词在从句充当句子成分,连接词whether和if(是否),asif(好像)在从句中不充当句子成分,只起连接作用。根据句义,如果连接代词与连接副词,whether、if和asif都用不上时,才用that作连接词(that本身无任何含义)。
二、主语从句
1.主语从句在复合句作主语。
e.g.Whowillgoisnotimportant.
2.用it作形式主语,主语从句放在句末。
e.g.Itdoesn‘tmattersomuchwhetheryouwillcomeornot.
3.that引导主语从句时,不能省略。
e.g.Thathesuddenlyfellilllastweekmadeussurprised.
三、表语从句
1.表语从句在复合句中作表语,位于系动词之后。
e.g.Thequestionwaswhocouldgothere.
2.引导表语从句的连接词that有时可省去。
e.g.Myideais(that)wecangetmorecomradestohelpinthework.
四、宾语从句
1.宾语从句在复合句中作宾语。引导宾语从句的连词that一般可省略。
e.g.Ihope(that)everythingisallright.
2.介词之后的宾语从句,不可用which或if连接,要分别用what或whether.
e.g.Iminterestedinwhetheryouvefinishedthework……
Iminterestedinwhatyouvesaid.
3.whether与if都可以引导宾语从句,常可互换。但下面情况不能互换。
(1)宾语从句是否定句时,只用if,不用whether.
e.g.Iwonderifitdoesntrain.
(2)用if会引起误解,就要用whether.
e.g.Pleaseletmeknowwhetheryouwanttogo.(此句如果把whether改成if,容易当成条件句理解)
(3)宾语从句中的whether与ornot直接连用,就不能换成if;不直接连用,可换。
e.g.Idontknowwhetherornotthereportistrue.
Idontknowwhether/ifthereportistrueornot.
(4)介词后的宾语从句要用whether引导。whether可与不定式连用。whether也可引导主语从句、表语从句、同位语从句,还可引导让步状语从句,以上均不能换成if.但引导条件从句时,只能用if,而不能用whether.
e.g.Itdependsonwhetherwehaveenoughtime.
Theydontknowwhethertogothere.
Pleasecometoseemeifyouhavetime.
五、同位语从句
同位语从句在句中作某一名词的同位语,一般位于该名词(如:news,fact,idea,suggestion,promise等)之后,说明该名词的具体内容。
e.g.Ihavenoideawhenhewillbeback.
Thefactthathehadnotsaidanythingsurprisedeverybody.<m.jAB88.Com/p>

一名优秀的教师在每次教学前有自己的事先计划,作为高中教师就要早早地准备好适合的教案课件。教案可以让学生能够在教学期间跟着互动起来,减轻高中教师们在教学时的教学压力。高中教案的内容要写些什么更好呢?下面是小编帮大家编辑的《高考英语名词性从句语法复习》,欢迎大家阅读,希望对大家有所帮助。

高中英语语法之名词性从句
在句子中起名词作用的句子叫名词性从句(NounClauses)。名词性从句的功能相当于名词词组,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,名词性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。
一、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:
连词:that(无任何词意)whether,if(均表示“是否”表明从句内容的不确定性)asif,asthough(均表示“好像”,“似乎”)以上在从句中均不充当任何成分
连接代词:what,whatever,who,whoever,whom,whose,whichever,whomever
连接副词:when,where,how,why,howmany,howmuch,howoften
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。
Thatshewaschosenmadeusveryhappy.Weheardthenewsthatourteamhadwon.
比较:whether与if均为"是否"的意思。但在下列情况下,只可用whether:
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"ornot"
Whetherhewillcomeisnotclear.
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。
Itisnotimportantwhowillgo.Itisstillunknownwhichteamwillwinthematch.
二.主语从句
1、作句子主语的从句叫主语从句。主语从句通常由从属连词that,whether,if和连接代词what,who,which,whatever,whoever以及连接副词how,when,where,why等词引导。that在句中无词义,只起连接作用;连接代词和连接副词在句中既保留自己的疑问含义、又起连接作用,在从句中充当从句的成分。例如:
Whathewantstotellusisnotclear.他要跟我们说什么,还不清楚。
Whowillwinthematchisstillunknown.谁能赢得这场比赛还不得而知。
Itisknowntoushowhebecameawriter.我们都知道他是如何成为一名作家的。
WheretheEnglisheveningwillbeheldhasnotyetbeenannounced.英语晚会将在哪里举行,还没有宣布。
有时为避免句子头重脚轻,常用形式主语it代替主语从句作形式主语放于句首,而把主语从句置于句末。主语从句后的谓语动词一般用单数形式。常用句型如下:
(1)It+be+名词+that从句(2)It+be+形容词+that从句(3)It+be+动词的过去分词+that从句(4)It+不及物动词+that从句
另注意在主语从句中用来表示惊奇、不相信、惋惜、理应如此等语气时,谓语动词要用虚拟语气“(should)+do”,常用的句型有:Itisnecessary(important,natural,strange,etc.)that…Itissuggested(requested,proposed,desired,etc.)that…
2、第一部分:常规主语从句,即句子在复合句中充当一个主语
主语从句的时态:不受主句的时态影响和限制。
(1)Thathefinishedwritingthecompositioninsuchashorttimesurprisedusall.
(2)Whetherwewillgoforanoutingtomorrowremainsunknown.
(3)Whowillbeourmonitorhasntbeendecidedyet.
(4)Whomwemuststudyforisaquestionofgreatimportance.
(5)Whatcausedtheaccidentremainsunknown.
(6)Whateveryoudidisright.
(7)Whothewatchbelongstowaslostisunknown.
(8)Whatweneedistime.
(9)Whatweneedaregooddoctors.
小结:(1)引导主语从句连词有that,whether,who,what,whatever等(2)连词位于句首不能省略(3)主语从句大多数情况下视为三单,但也有例外,如例9
第二部分:为了防止句子头重脚轻,通常把形式主语it放在主语位置,真正主语搁置于句末
(1)Itiscertainthathewillwinthematch.
(2)Itistruethathehasmadeaveryimportantdiscoveryinchemistry.
(3)Itisverylikelythattheywillholdameeting.
(4)Itisstrangethatheshoulddothat.
(5)Itisimportantthatweallshouldattendthemeeting.
(6)Itisstrangethatthemanshouldhavestucktohissillyideas.
(7)Itisapitythatwewontbeabletogotothesouthtospendoursummervacation.
(8)Itisstillamysterywhatcausedtheaccident.
(9)Itissaidthathehasgonetoshanghai.(=Heissaidtohavegonetoshanghai)
(10)ItisknowntoallthatthegunpowderwasfirstinventedbytheChinese.
(11)Itissuggestedthattheworkshouldbedonewithgreatcare.
(12)Itseemsthathehasseenthefilm.(=Heseemstohaveseenthefilm)
(13)Ithappenedthatthetwocheatswerethere.(=Thetwocheatshappenedtobethere)
小结:(1)以that引出的主语从句,常以形式主语it引导.Itis+形容词/名词/某些动词ed+that从句.(2)在有些that从句中要用虚拟语气(should+do/should+havedone)例句4,5,6,11.
3、主语从句的用法
主语从句是在复合句中充当主语的从句,通常放在主句谓语动词之前或由形式主语it代替,而本身放在句子末尾。
1.It作形式主语和it引导强调句的比较
It作形式主语代替主语从句,主要是为了平衡句子结构,主语从句的连接词没有变化。而it引导的强调句则是对句子某一部分进行强调,无论强调的是什么成分,都可用连词that。被强调部分指人是也可用who/whom。例如:Itisapitythatyoudidn’tgotoseethefilm.
2.用it作形式主语的结构
(1)Itis+名词+从句
Itisafactthat…事实是…Itisanhonorthat…非常荣幸
Itiscommonknowledgethat…是常识
(2)itis+形容词+从句
Itisnaturalthat…很自然…Itisstrangethat…奇怪的是…
(3)it+不及物动词+从句
Itseemsthat…似乎…Ithappenedthat…碰巧…
(4)itis+过去分词+从句
Itisreportedthat…据报道…Ithasbeenprovedthat…已证实…
3.主语从句不可位于句首的五种情况
(1)if引导的主语从句不可居于复合句句首。
(2)Itissaid,(reported)…结构中的主语从句不可提前。例如:
ItissaidthatPresidentJingowillvisitourschoolnextweek.
(3)Ithappens…,Itoccurs…结构中的主语从句不可提前。例如:
Itoccurredtohimthathefailedintheexamination.
(4)Itdoesn’tmatterhow/whether…结构中的主语从句不可提前。例如:
Itdoesn’tmatterwhetherheiswrongornot.
(5)含主语从句的复合句是疑问句时,主语从句不可提前。例如:
Isitlikelythatitwillrainintheevening?
4.What与that在引导主语从句时的区别
What引导主语从句时在从句中充当句子成分,如主语.宾语.表语,而that则不然。例如:Whatyousaidyesterdayisright.
三、宾语从句
名词句用作宾语的从句叫宾语从句。引导宾语从句的关联词与引导主语从句表语从句的关联词大致一样,在句中可以作谓语动词或介词及非谓语动词的宾语。
1.由连接词that引导的宾语从句
由连接词that引导宾语从句时,that在句中不担任任何成分,在口语或非正式的文体中常被省去,但如从句是并列句时,第二个分句前的that不可省。例如:
HehastoldmethathewillgotoShanghaitomorrow.他已经告诉我他明天要去上海。
Wemustneverthink(that)wearegoodineverythingwhileothersaregoodinnothing.我们决不能认为自己什么都好,别人什么都不好。
注意:在demand、order、suggest、decide、insist,desire,request,command等表示要求、命令、建议、决定等意义的动词后,宾语从句常用“(should)+动词原形”。例如:
Iinsistthatshe(should)doherworkalone.我坚持要她自己工作。
Thecommanderorderedthattroops(should)setoffatonce.司令员命令部队马上出发。
2.用who,whom,which,whose,what,when,where,why,how,whoever,whatever,whichever等关联词引导的宾语从句相当于特殊疑问句,应注意句子语序要用陈述语序。例如:Iwanttoknowwhathehastoldyou.我想知道他告诉了你什么。
Shealwaysthinksofhowshecanworkwell.她总是在想怎样能把工作做好。
Shewillgivewhoeverneedshelpawarmsupport.凡需要帮助的人,她都会给予热情的支持。
3.用whether或if引导的宾语从句,其主语和谓语的顺序也不能颠倒,仍保持陈述句语序。此外,whether与if在作“是否”的意思讲时在下列情况下一般只能用whether,不用if:
a.引导主语从句并在句首时;b.引导表语从句时;c.引导从句作介词宾语时;d.从句后有“ornot”时;e.后接动词不定式时。例如:
Whetherthereislifeonthemoonisaninterestingquestion.月球上有没有生命是个有趣的问题。Thequestioniswhethersheshouldhavealowopinionofthetest?现在的问题是她是否应该有一个低意见的测试?Everythingdependsonwhetherwehaveenoughmoney.一切要看我们是否有足够的钱。Iwonderwhetherhewillcomeornot.我想知道他来还是不来。Canyoutellmewhethertogoortostay?你能否告诉我是去还是留?
4.注意宾语从句中的时态呼应,当主句动词是现在时,从句根据自身的句子情况,而使用不同时态。例如:
hestudiesEnglisheveryday.(从句用一般现在时)
hestudiedEnglishlastterm.(从句用一般过去时)
Iknow(that)hewillstudyEnglishnextyear.(从句用一般将来时)
hehasstudiedEnglishsince1998.(从句用现在完成时)
当主句动词是过去时态(could,would除外),从句则要用相应的过去时态,如一般过去时,过去进行时,过去将来时等;当从句表示的是客观真理,科学原理,自然现象,则从句仍用现在时态。例如:TheteachertoldusthatTomhadleftusforAmerica.
5.think,believe,imagine,suppose等等动词引起的否定性宾语从句中,要把上述主句中的动词变为否定式。即将从句中的否定形式移到主句中。例如:
Wedon’tthinkyouarehere.我们认为你不在这。
Idon’tbelievehewilldoso.我相信他不会这样做。
6.时态:1.主句用一般现在时,从句可用任意时态。2.主句用过去时,从句用过去某个时态。
3.主句用过去时,从句是客观真理时,只用一般现在时。
7.宾语从句的连接词
从属连词:连接宾语从句的从属连词主要有that,if,whether.that引导表示陈述句的宾语从句,而if和whether引导表示“是否”的宾语从句.
Hetoldmethathewouldgotothecollegethenextyear他告诉我他明年上大学.
Idon’tknowiftherewillbeabusanymore.我不知道是否还会有公交车.
Nobodyknewwhetherhecouldpasstheexam.没人知道他是否会通过考试.
连接代词:连接代词主要有who,whom,whose,what,whoever,whomever,whosever,whatever,whichever等.连接代词一般指疑问,但what,whatever除了指疑问外,也可以指陈述.

ThebookwillshowyouwhatthebestCEOsshouldknow.
这本书会告诉你最好的执行总裁该了解些什么.

Noneofusknowswherethesenewpartscanbebought.
没有人知道这些的新的零件能在哪里买到.
8.动词的宾语从句

他很高兴在他生病的时候李明能去看望他.
11.if,whether在宾语从句中的区别
①if和whether在作“是否”解时,引导宾语从句常放在动词know,ask,care,wonder,findout等之后,介词后一般不用if②少数动词,如:leave,put,discuss,doubt后的宾语从句常用whether.③whether后可以加ornot,但是if不可以.④在不定式前只能用whether.(如:Ican’tdecidewhethertostay.我不能决定是否留下。)⑤避免歧异时,我们常用whether而不用if.
12.哪些宾语从句不可以省略引导词that
1.当that作learn,suggest,explain,agree,wonder,prove,mean,state,feel,hold等动词的宾语时;2.当宾语从句较长时;3.当主语状语置于主句尾,宾语从句之前时;4.当主语谓语动词(包括非谓语动词)与宾语从句之间有插入语时;5.当一个动词带有两个或两个以上宾语从句时,此时第一个that可以省略,第二个that不可以省略;6.当宾语从句中的主语是this,that或this,that做主语的定语时;7.当宾语从句是双宾语中的直接宾语时;当宾语从句的主语是非谓语动词或主语从句时;8.当主语中的谓语动词是固定词组时;9.当宾语从句有it做其先行词时;10.在直接引语中,转述分句把宾语从句隔开时.
13.宾语从句的否定转移
主句的谓语动词是think,believe,imagine,suppose,consider,espect,fancy,guess等,并且主句的主语是第一人称而且为一般现在时,从句的否定词一般要转移到主句上来,其反义疑问句一般与宾语从句一致.

我们发现他从来不仔细听老师讲课,是不是?
14.宾语从句的时态和语序
当主句为现在时或将来时,宾语从句的时态一般不受主句的时态所影响.
当主句为过去时
①从句用一般过去时或过去进行时表示与主句谓语动词动作同时发生
Ionlyknewhewasstudyinginawesterncountry,butIdidn’tknowwhatcountryhewasin.
我只知道他当时在西方的一个国家读书,可不知道是哪个国家.

你认为今年公众会选谁为他们最喜欢的歌手.
四、表语从句
1、在句中作表语的从句叫表语从句。引导表语从句的关联词与引导主语从句的关联词大致一样,表语从句位于连系动词后,有时用asif引导。其基本结构为:主语+系动词+that从句。例如:
Thefactisthatwehavelostthegame.事实是我们已经输了这场比赛。
That’sjustwhatIwant.这正是我想要的。
Thisiswhereourproblemlies.这就是我们的问题所在。
Thatiswhyhedidn’tcometothemeeting.那就是他为什么不到会的原因。
Itlooksasifitisgoingtorain.看上去天要下雨了。
需要注意的,当主语是reason时,表语从句要用that引导而不是because。例如:
Thereasonwhyhewaslatewasthathemissedthetrainbyoneminutethismorning.
whether可引导表语从句,但与之同义的if却通常不用于引导表语从句。
2、简介
定义:A表语从句就是用一个句子作为表语。说明主语是什么或者怎么[1]样,由名词、形容词或相当于名词或形容词的词或短语充当,和连系动词一起构成谓语。
Theproblemispuzzling.这问题令人困惑
主语连系动词形容词作表语
Theproblemiswhenwecangetapayrise.问题是什么时候我们可以得到加薪.
主语连系动词一个句子作表语---表语从句
B连接表语从句的连接词有:that,what,who,when,where,which,why,whether,how.
Hehasbecomeateacher.他已经成为一名教师。
Hehasbecomewhathewantedtobetenyearsago.他已经成为了他10年前想成为的。
Shehasremainedthereforanhour.她曾在那里停留了一个小时。
ShehasremainedwhereIstoodyesterdayforanhour.她一直在我昨天站的地方站了一个小时。
Hissuggestionisgood.他的建议是好的。
Hissuggestionisthatweshouldstaycalm.他的建议是,我们应该保持冷静。
Thequestionisconfusing.这个问题令人困惑.
Thequestioniswhenhecanarriveatthehotel.问题是,他什么时候可以到达酒店。
whowilltravelwithmetoBeijingtomorrow.谁与我明天将前往北京。
whyhecriedyesterday.昨天他为什么哭。
howIcanpersuadehertojoinusintheparty.我怎么能说服她加入我们的派对。
whethertheenemyismarchingtowardsus.是否敌人正向我们行进.
注意:
A表语从句一定要用陈述语序。
False:Thequestioniswhencanhearriveatthehotel.
Right:Thequestioniswhenhecanarriveatthehotel.
B不可以用if,而用whether连接表语从句(asif例外)。
引导宾语从句时可以互换if/whether位于介词后要用whether
位于句首时要用whether
引导表语从句,主语从句,同位语从句时要用whether
False:Thequestionisiftheenemyismarchingtowardsus.
Right:Thequestioniswhethertheenemyismarchingtowardsus.
Right:Itlookedasifhehadunderstoodthisquestion.
C不像宾语从句,在有表语从句的复合句中,主句时态和从句时态可以不一致。
Right:ThequestioniswhowilltravelwithmetoBeijingtomorrow.
Right:Thequestioniswhyhecriedyesterday.
Dthat在表语从句中不可以省掉。
3、基本用法
表语从句只能置于主句之后,而主句的动词只能是联系动词。
名词性从句在be等系动词后作表语时被称为表语从句,例如:Theproblemishowwecangetthethingsweneed.问题是我们怎样能弄到我们需要的东西。(how在表语从句中充当方式状语)//ThescissorsarenotwhatIneed.这把剪刀不是我所需要的。(what在表语从句中充当宾语)//WhatItoldhimwasthatIwouldfindhimagoodplay.我告诉他的是我会给他找个好剧本。(what在主语从句中作直接宾语,that作为表语从句的引导词在该表语从句中不充当句子成分,不能省略)//ThatiswhatIwanttotellyou.那就是我想要对你讲的。(what在表语从句中充当直接宾语)//Thatiswhyshefailedtopasstheexam.那就是她考试不及格的原因。(why在表语从句中充当原因状语)
注意:“Thatiswhy...”是常用句型,意为“这就是……的原因/因此……”,其中why引导的名词性从句在句中作表语,该句型通常用于针对前面已经说明过的原因进行总结,又如:Thatiswhyyouseethisoldwomanbeforeyouknow,Jeanne.珍妮,这就是现在这个老太婆出现在你面前的原因。(前文提到Jeanne对老妇人显得苍老憔悴深感诧异,说话人对她讲述了其中的原因之后,用这一句来进行概括)。//ThatiswhyIcame.这就是我来的原因。
下面是两个与“Thatiswhy...”形式相似的结构,它们与“Thatiswhy...”结构之间的关系要能够辨析清楚:
(1)“Thatiswhy...”与“Thatisthereasonwhy...”同义,只不过从语法结构上讲,“Thatisthereasonwhy...”中why引导的是—个定语从句,将其中的thereason去掉则与“Thatiswhy...”结构一样,例如:Thatis(thereason)whyIcannotagree.这就是我不能同意的理由。
(2)“Thatisbecause...”句型中从属连词because引导的名词性从句在此作表语,这也是个常用句型,意为“这就是为什么……/因为……”。“Thatisbecause...”与“Thatiswhy...”之间的不同在于“Thatisbecause...”指原因或理由,“Thatiswhy...”则指由于各种原因所造成的后果,例如:Hedidnotseethefilmlastnight.Thatisbecausehehadtohelphislittlesisterwithherhomework.昨天晚上他没有去看电影,那是因为他得帮助他的妹妹做作业。(第一句话说明结果,第二句话说明原因)
Hehadseenthefilmbefore.Thatiswhyhedidnotseeitlastnight.他以前曾看过那部电影,因此他昨天晚上没有去看。(第一句话说明原因,第二句话说明结果)
五、同位语从句
1、同位语从句说明其前面的名词的具体内容。同位语从句通常由that引导,可用于同位语从句的名词有advice、demand、doubt、fact、hope、idea、information、message、news、order、problem、promise、question、request、suggestion、truth、wish、word等。例如:
Thenewsthatwewonthegameisexciting. 我们赢得这场比赛的消息令人激动。
Ihavenoideawhenhewillcomebackhome.我不知道他什么时候回来。
ThethoughtcametohimthatMaryhadprobablyfallenill.他想到可能玛丽生病了。
同位语从句和定语从句的区别:
that作为关系代词,可以引导定语从句,充当句子成分,在从句中作宾语时可以省略;that引导同位语从句时,起连词的作用,没有实际意义,不充当句子成分,一般不能省略。
试比较下面两个例句:
Ihadnoideathatyouwerehere.(that引导同位语从句,不能省略)
Haveyougottheidea(that)thisbookgivesyouoflifeinancientGreece?(that引导定语从句,作宾语,可以省略)
2、简介
同位语部分是个句子,就是同位语从句,这种用法比较"固定",把关键的几个词背下来.
一、在复合句中用作同位语的从句叫同位语从句。它一般跟在某些名词后面,用以说明该名词表示的具体内容。如:
Iheardthenewsthatourteamhadwon.我听到了我们队获胜的消息。
Ihadnoideathatyouwerehere.我不知道你在这里。
二、可以跟同位语从句的名词通常有news,idea,fact,promise,question,doubt,thought,hope,message,suggestion,words(消息),possibility等。如:
I’vecomefromMrwangwithamessagethathewon’tbeabletoseeyouthisafternoon.我从王先生那里来,他让我告诉你他今天下午不能来看你了。
三、英语中引导同位语从句的词通有连词that,whether,连接副词how,when,where等。(注:if,which不能引导同位语从句。)如:
lhavenoideawhenhewillbeback.我不知道他什么时候回来。
Hemustanswerthequestionwhetherheagreestoitornot.
他必须回答他是否同意这样一个问题。
四、有时同位语从句可以不紧跟在说明的名词后面,而被别的词隔开。如:
Severalyearslater,wordcamethatNapoleonhimselfwascomingtoinspectthem.
几年以后,有消息传来说拿破仑要亲自视察他们。
Thethoughtcametohimthatmaybetheenemyhadfledthecity.
他突然想起可能敌人已经逃出城了。
六、名词性that-从句
1)由从属连词that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:Thatsheisstillaliveisherluck. 他还活着全靠运气。
宾语:JohnsaidthathewasleavingforLondononWednesday. 约翰说他星期三要到伦敦去。
表语:Thefactisthathehasnotbeenseenrecently. 事实是近来谁也没有见过他。
同位语:Thefactthathehasnotbeenseenrecentlydisturbseveryoneinhisoffice.
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:Iamgladthatyouaresatisfiedwithyourjob.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:
Itisquiteclearthatthewholeprojectisdoomedtofailure. 很清楚,整个计划注定要失败。
Itsapitythatyoushouldhavetoleave. 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
Itisnecessarythat… 有必要……Itisimportantthat… 重要的是……
Itisobviousthat… 很明显……
b.It+be+-ed分词+that-从句
Itisbelievedthat… 人们相信……Itisknowntoallthat… 众所周知……
Ithasbeendecidedthat… 已决定……
c.It+be+名词+that-从句
Itiscommonknowledgethat… ……是常识Itisasurprisethat… 令人惊奇的是……
Itisafactthat… 事实是……
d.It+不及物动词+that-从句
Itappearsthat… 似乎……Ithappensthat… 碰巧……
Itoccurredtomethat… 我突然想起……
七、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:Howthebookwillselldependsonitsauthor. 书销售如何取决于作者本人。
直接宾语:Inonesownhomeonecandowhatonelikes. 在自己家里可以随心所欲。
间接宾语:Theclubwillgivewhoeverwinsaprize. 俱乐部将给得胜者设奖。
表语:MyquestioniswhowilltakeoverpresidentoftheFoundation. 我的问题是谁将接任该基金会主席职位。
宾语补足语:Shewillnamehimwhatevershewantsto.她高兴给他起什么名字就取什么名字。
同位语: Ihavenoideawhenhewillreturn. 我不知道他什么时候回来。
形容词宾语:Imnotsurewhysherefusedtheirinvitation. 我尚不能肯定她为什么拒绝他们的邀请。
介词宾语: Thatdependsonwhereweshallgo. 
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:
Itisnotyetdecidedwhowilldothatjob. 还没决定谁做这项工作。
Itremainsunknownwhentheyaregoingtogetmarried. 他们何时结婚依然不明。
八、if,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:Whethertheplanisfeasibleremainstobeproved.这一计划是否可行还有等证实。
宾语:Letusknowwhether/ifyoucanfinishthearticlebeforeFriday. 请让我们知道你是否能在星期五以前把文章写完。
表语:Thepointiswhetherweshouldlendhimthemoney. 问题在于我们是否应该借钱给他。
同位语:Theyareinvestigatingthequestionwhetherthemanistrustworthy. 他们调查他是否值得信赖。
形容词宾语:Shesdoubtfulwhetherweshallbeabletocome. 她怀疑我们是否能够前来。
介词宾语:Iworryaboutwhetherhecanpassthroughthecrisisofhisillness. 我担心他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/whether…or或whether…ornot构成,例如:
Pleasetellmewhether/iftheyareSwedishorDanish.请告诉我他们是瑞典人还是丹麦人。
Idontcarewhetheryouliketheplanornot.我不在乎你是否喜欢该计划。
if和whether的区别:
1、在动词不定式之前只能用whether。如:
例8Ican’tdecidewhethertostay.我不能决定是否留下。
2、在whether……ornot的固定搭配中。如:
例9Iwanttoknowwhetherit’sgoodnewsornot.我想知道是否是好消息。
3、在介词后,只能用whether。如:
例10Hisfatherisworriedaboutwhetherhelosehiswork.他的父亲担心是否会失去工作。
4、宾语从句放在句首表示强调时,只能用whether。如:
Whetherthisistrueornot,Ireallydon’tknow.这是否真的,我真的不知道。
(例11Whethertheycanfinishtheworkontimeisstillaproblem.他们是否能准时完成这项工作还是个问题。--此例为主语从句,有误,感谢指出)
5、用if会引起歧义时,只用whether。如:
例12Couldyoutellmeifyouknowtheanswer?
这句话有两种意思:“你能告诉我是否知道答案吗?”或“如果你知道答案,请告诉我,好吗?”。如用whether可避免歧义.
九、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。
IdontthinkIknowyou. 我想我并不认识你。
Idontbelievehewillcome. 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。
Ihopeyouwerentill.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。
Itdoesntseemthattheyknowwheretogo.看来他们不知道往哪去。
Itdoesntappearthatwellhaveasunnydaytomorrow.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。
Idontrememberhavingeverseensuchaman. 
我记得从未见过这样一个人。(not否定动名词短语having…)
Itsnotaplacewhereanyonewouldexpecttoseestrangecharactersonthestreet.
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。
Theantisnotgatheringthisforitselfalone. (否定状语) 蚂蚁不只是为自己采食。
HewasnotreadytobelievesomethingjustbecauseAristotlesaidso.(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。
Shehadnotbeenmarriedmanyweekswhenthatmansyoungerbrothersawherandwasstruckbyherbeauty. (否定状语manyweeks) 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。
十、高考热点透视
1.___isafactthatEnglishisbeingacceptedasaninternationallanguage.(NMET1995)
A.ThereB.ThisC.ThatD.It
答案D。当名词从句在句中作主语时,为避免句子头重脚轻,常用it作形式主语置于句首,而将真正的主语从句放在句尾。此时it只起先行引导作用,本身无实义。此句也可以改写为:ThatEnglishisbeingacceptedasaninternationallanguageisafact.
2.Acomputercanonlydo____youhaveinstructedittodo.(NMET2001)
A.howB.afterC.whatD.when
答案C。从句子结构可知,句子的空白处应该填引导宾语从句的连词,做主句谓语动词do的宾语,同时该连接词还是从句中的do的宾语,因此,此处的连接词应该用what。
3.Heasked____foraviolin.(MET1992)
A.didIpayhowmuchB.IpaidhowmuchC.howmuchdidIpayD.howmuchIpaid
答案:D。宾语从句相当于特殊疑问句,句子语序要用陈述语序。
4.Whatthedoctorsreallydoubtis____mymotherwillrecoverfromtheseriousdiseasesoon.(上海2001年春季招生)
A.whenB.howC.whetherD.why
答案C。这是一个表语从句。根据doubt一词可知,所怀疑的应是是否能治好病,所以要填whether。这句话的意思是“医生真的怀疑我妈妈是否能很快从重病中恢复过来。”
5.Itisgenerallyconsideredunwisetogiveachild_____heorshewants.(NMET1997)
A.howeverB.whateverC.whicheverD.whenever
答案B。根据句意“一般认为孩子要什么就给什么是不好的。”可以看出后面的从句应是一个宾语从句,而从句中wants缺少宾语,A.however和D.whenever是不能作宾语的;排除A和D,whichever表示“无论哪一个,无论哪些”,应表示一定范围内的人或物,此处没有涉及事物的范围,所以应选B.whatever,表示“无论什么”。
6.______leavestheroomlastoughttoturnoffthelights.(MET1988)
A.AnyoneB.ThepersonC.WhoeverD.Who
答案C。本题句子的意思是:无论谁最后离开房间一定要把灯关掉。本题考查连接代词whoever引导的名词性从句,连接代词whoever可以引导名词性从句,并在从句中作主语,相当于anypersonwho或Thepersonwho,意为“一切……的人”。而anyone和theperson均非连词,不能引导从句,况wholeavestheroomlast意为“某个最后离开房间的人”,与题意不符,如果要选A.Anyone或B.Theperson,都必须在它们后面再加上引导定语从句的关系代词who。如果要选D.Who就体现不出“无论谁”的含义了。
7.Sarahhopestobecomeafriendof______sharesherinterests.(Shanghai1995)
A.anyoneB.whomeverC.whoeverD.nomatterwho
答案为C。本题句子的意思是:Sarah希望跟自己有共同爱好的人交朋友。疑问词+ever引导的名词性从句与nomatter+疑问词引导的从句的区别是:前者既可以引导名词性从句也可以引导让步状语从句;后者只能引导让步状语从句。首先排除A和D,从句中需要的是主语,所以whomever也不行。
8.----IdrovetoZhuhaifortheairshowlastweek.
----Isthat______youhadafewdaysoff?(NMET1999)
A.whyB.whatC.whenD.where
答案A。根据语境,甲说上周驱车去珠海观看航模展览。乙据此来询问甲这是否是请几天假的原因,故答案是A。答案B,C,D均与该题语境不符。根据上句提供的语境,下句应该问“那就是你为什么离开几天的原因吗?”
9.Istillremember______thisusedtobeaquietvillage.(NMET1993)
A.whenB.howC.whereD.what
答案A。根据从句中缺少的句子成分是状语,排除D.what,而答案C,D均与题意不符,所以应选A.when。usedtobe表示一种过去存在的状态,本句的意思是“我仍然记得这里在什么时候是个宁静的地方。”
10.Ireadaboutitinsomebookorother,doesitmatter____itwas?(2001春季招生)
A.whereB.whatC.howD.which
答案D。这是一个主语从句。主语从句中缺少表语。从上句的意思分析,应是哪本书,所以要填which,这句话的意思是“我在某本书中读到过有关这方面的内容,是哪一本书重要吗?”。
11.Informationhasbeenputforward____moremiddleschoolgraduateswillbeadmittedintouniversities.
A.whileB.thatCwhenD.as(2001年上海)
答案B。该题考查that引导的同位语从句。同位语从句通常由that引导,接在fact,news,promise,possibility,information,doubt,message名词后,用来解释或说明名词的内容。
12.—Ithinkitisgoingtobeabigproblem.—Yes,itcouldbe.
—Iwonder______wecandoaboutit.(北京2002春季)
A、ifB、howC、whatD、that
答案C。本题考察名词性从句的连接词的用法。wonder后面应跟宾语从句,而从句中的谓语动词do是及物动词,可见从句缺少一个代替宾语的成分,我们可以用排除法排除不作成分的if和that,再排除引导方式状语的how,答案是C,句子的意思是“我们能就此做些什么”。

名词性从句


知识扫描
复合句中具有名词性质并且可以做主语、表语、同位语或宾语的从句叫名词性从句。因此,我们把主语从句、表语从句、同位语从句和宾语从句这四种从句统称为名词性从句。
高考热点
1)怎样判断名词性从句的类别;
2)连词that和what的用法与选择
3)if与whether的区别
4)同位语从句与定语从句的区别
5)名词性从句必须采用的陈述语序
6)it可充当形式主语和形式宾语
7)疑问词+-ever的连词和不加-ever的连词在语义上的用法和差别
核心解读一
1、在名词性从句中,从句都用陈述语序。
2、引导名词性从句的词叫引导词。引导词可以分为以下几类:
1)从属连词that(用于表示肯定的含义),whether,if(表示疑问),这三个词只起连接作用,不充当从句中的任何成分,除宾语从句外(that可省),这些词均不可省略。
2)连接代词有who,whom,whose,what,which,whoever,whatever,whichever等。这些词在从句中既起连接作用,又充当从句中的成分,如主语、宾语、表语、补语,且不可省略。
3)连接副词有when,where,why,how,wherever,however等。它们既起连词作用,本身又做从句中的状语。
3、名词性从句中的时态一致问题
1)在宾语从句中,当主句是一般现在时、将来时或现在完成时,起从句的谓语根据需要用适当的时态。当主句是一般过去时,从句用过去的某个时态,但若宾语从句表示客观真理,格言,谚语等,从句的时态仍用一般现在时。
Haveyoutoldhimthatwhenwearetoleave?
TeachertoldusthatChinaliesinthewestofJapan.
Althoughshewaslistening,shedidn’thearwhathewassayingbecausetherewassomuchnoise.
2)在主语从句、表语从句或同位语从句中,应注意主语从句中的谓语动词的时态一致性及动作发生的先后关系。
4、语气
在名词性从句中,谓语动词根据需要可以用虚拟语气。起从句的谓语动词用should+动词原形,should可以省略。
核心解读二:主语从句
1.Whether与if
Whether可以引导主语从句置于句首,而if不放在句首。
特别提醒:
1)if可引导条件状语从句,而Whether不可,若宾语从句为否定句,则用if。
Idon’tcareifhewon’tcome.Ifitrainstomorrow,wewon’tgo.
2)类似下面的句子也用that.
Thereisnodoubtthathewillcome.
Itwasneverdoubtfulthathewouldhelpus.
3)下面情况下多用whether。
(1)在表语从句或同位语从句中。
(2)宾语从句置于主句前(即前置以示强调)
(3)宾语从句做介宾(含discuss的宾语)
(4)后面紧跟ornot或动词不定式
(5)引导让步状语从句
(6)引导宾语从句可能产生歧义时
例1
Hedoesn’tknow_____tostayornot.
A.whetherB.ifC.eitherD.ifhewill
[Key]A
[点拨]后面有动词不定式和ornot。
例2
Idon’tthinkthequestionof_____theyareoldoryoungisimportant.
A.whichB.whetherC.howD.why
[Key]B
[点拨]宾语从句做介宾
2.That与what
在名词性从句中,thatb不充当句子成分,仅起连接作用,也无意义,而what可充当主语、宾语、表语等,起含义为“……的事(东西)”。
Hasitbeendecidedthattheartistwillattendthemeeting?
WhatthechildrenlooksforwardtomostwastheNewYear’scoming?
例3
_____fashiondiffersfromcountrytocountrymayreflecttheculturedifferencesfromoneaspect.
A.WhatB.ThatC.ThisD.Which
[Key]Bthat
[点拨]不做成分,但引导的是主语从句,所以不能省略。
例4
_____causedtheaccidentisstillacompletemystery.
A.WhatB.ThatC.HowD.Where
[Key]A
[点拨]what在句子中做主语。
3.主语从句可用形式主语it代替,置于句首,而将真整的主语即主语从句放在后面。但what,whatever和whoever引导的主语从句不用it代替。
Itiscertainthatshewillbelate.
例5
Itisprettywellunderstand_____controlstheflowofcarbondioxideinandouttheatmospheretoday.
A.whichB.thatC.whatD.whether
[Key]C
[点拨]It为形式主语,what引导的句子做真正的主语。
例6
Itworriedherabit_____herhairwasturninggrey.
A.whileB.ifC.thatD.for
[Key]C
[点拨]It为形式主语,而真正的主语是有that引导的从句。
特别提醒:
1)主语从句的that在口语或非正式文体中如果不在句首可以省略,但that从句位于句首时决不能省略。
It’sapity(that)youareleaving.
Itiscertain(that)shewilldowellintheEnglishexam.
2)主语从句除了that外,还可以用where,whether,when,why等词引导。
Itdoesn’tmatterwhethertheywillcomeornot.
Ithasnotbeenyetdecidedwhowillspeakatthemeeting.
4.who与whoever
whoever意思为“凡……者”相当于anyonewho+定语从句。它既可作主句的主语,又可作从句的主语,强调人。而who引导主语从句,只在从句中作主语,强调事。
Whoeverismoreorlessadvancedcanpassthetext.
Iwillgivethisdictionarytowhoeverwinthegames.
例7
_____leavestheroomlastoughttoturnoffthelights.
A.AnyoneB.ThepersonC.whoeverD.Whom
[Key]C
[点拨]whoever=anyonewho
例8
Tomhopestobecomeafriendof_____sharesherinterests.
A.anyoneB.whomeverC.whoeverD.nomatterwho
[Key]C
[点拨]whoever引导的句子做介宾而nomatterwho不引导名词性从句,只引导让步状语从句。
例9
Itwasamatterof_____wouldtaketheposition.
A.whoB.whoeverC.whomD.whomever
[Key]A
[点拨]省略
5.主语从句不可位于句首的四种情况.
(1)Itissaid,(reported)…结构中的主语从句不可提前。
例如:
ItissaidthatPresidentJingowillvisitourschoolnextweek.(Right)
ThatPresidentJiangwillvisitourschoolnextweekissaid.(Wrong)
(2)Ithappens…,itoccurs…结构中的主语从句不可提前。
例如:
Itoccurredtohimthathefailedintheexamination.(Right)
Thathefailedintheexaminationoccurredtohim.(Wrong)
(3)Itdoesn’tmatterhow/whether…结构中的主语从句不可提前。
例如:
Itdoesn’tmatterwhetherheiswrongornot.(Right)
(4)含主语从句的复合句是疑问句时,主语从句不可提前。
例如:
Isitlikelythatitwillrainintheevening?(Right)
Isthatwillrainintheeveninglikely?(Wrong)
核心解读三宾语从句
宾语从句多做及物动词的、介词的宾语。
1.语序用陈述语序
例10
Someoneisringingthedoorbell.Goandsee_____.
A.whoisheB.whoheisC.whoisitDwhoitis
[点拨]作动词see的宾语从句要用陈述语序,当无法区别男女时,用it作主语。
特别提示:
1)特殊疑问词做主语时,次序不再变化。
Pleasetelluswhowillgiveusatalkthisweekend!
2)宾语从句的标点符号由主语来决定。
Don’tyouthinkthatthelightintheroomistoodark?
2)在宾语从句中不能用一般现在时表示将来,也不能用一般过去时表将来。
3)在doubt的否定句中,doubt后的宾语从句用that,在doubt的肯定句中用Whether或if均可。
Wedon’tdoubtthathewillsucceedintheresearchwork.
Idoubtif/whetheritistrue.
Wedon’tdoubtthathecandoagoodjobofit.
例11
Wewereallsurprisedwhenhemadeitclearthathe_____officesoon.
A.leavesB.wouldleaveC.leftD.hadleft
[Key]B
[点拨]本句子是过去时间,soon的出现就是表示过去将来。干扰项答案A以一般现在实施表示将来时,是适用于条件状语从句,故不正确!
3.连接词的选用关键要理解、弄清楚各自的含义和在句子中做的成分。
例12
Iremember_____thisusedtobeaquietvillage.
A.whenB.howC.whereD.what
[Key]A
[点拨]本题考查宾语从句的连词。how和where在从句中分别作地点和方式状语,在此不合题意,而此句是一个完整句子即主系表结构,故排除what。本句欲表示的意思是:“我记得那个时候这里曾经是一个安静的村庄”
例13
Iwoulddo_____Icandotohelpthem.
A.thatB.whateverC.whichD.whichever
[Key]B
[点拨]Icando句中的及物动词do没有宾语,句子不完整,缺句子成分,whatever在句中可以作do的宾语。
4.That在宾语从句中不可省略的情况。
1)当that引导的宾语从句中的状语紧靠that时,或者说that从句中含有主从复合句时。
I’msurethatifyou’velostit,youmastpayforit.
2)当宾语从句被it替代时
Shehasmadeitclearthatshewillhavenothingtodowiththedecision.
3)当由两个that引导的从句作同一个动词或介词的宾语时,第二个that不可省。
Tomtoldtheleader(that)Jonehadworkerveryhardandthathewantedhimstay.
4)有插入语或其它成分把宾语从句和主句分开时。
Hethinks,I’mafraid,thatheisalwaysright.
5)当that引导的宾语从句的主语是非谓语动词或主语从句时。
Theysaidthatrubbingthegirl’slegmighthelp.
6)从句的主语是that时。
Shesaysthatthatisarealgoldring.
5.It可充当形式宾语,代替真正的宾语从句,此时谓语动词除带宾语从句外,还带宾补。
Theywanttomakeitcleartothepublicthattheydoanimportantjob.
核心解读四表语从句
1.当reason和cause引导的从句做主语时,其表语从句多用that引导,而不用because引导。
Thereasonwhyhewaslatewasthathemissedthelastbus.
2.because引导表语从句时,一般在句型“it(that,this)isbecause…”中说明原因;而在“it(that,this)iswhy…”中说明结果。
Theteacherwasveryangry.Thatwasbecausehewasverylate.
Hewasverylate.Thatwaswhytheteacherwasangry.
3.asif/asthough也可引导表语从句。
Itlooksasif/asthoughitweregoingtorain.
4.除that和wh-词外,as也可引导表语从句。
Thingsarenotalwaysastheyseemtobe.
核心解读五同位语从句
1.同位语从句语序为陈述语序,多放在下列词的后面,如:idea,fact,news,hope,wish,promise,doubt,suggestion,truth,question,problem,belief,probability….对其名词起进一步说明作用,是名词的具体内容。
例14
Ihavenoidea_____fartheairportisfromhere.
A.whatB.howC.it’sD.that
[Key]B
例15
There’safeelinginme_____we’llneverknowwhataUFOisnotever.
A.thatB.whichC.ofwhichD.what
[Key]A
[点拨]that引导的同位语从句修饰feeling
2.That引导同位语从句与定语从句的区别
That引导同位语从句时,在从句中不充当任何成分,只起连接作用,但不可省略,而that在定语从句中可做主语、宾语和表语。作宾语时可省略。
Thenewsthathepassedtheexamwasagreatsurprise.(同位语从句)
Thenews(that)hetoldmewasagreatsurprise.(宾语从句)
核心解读六名词性从句中的几类问题特别提示
1、当疑问词做主语或主语的定语时的语序不变。
Allofusaskedherwhatwasthematter/wrong/thetroublewithherface.(做主语)
Tomaskedmewhosepenwasred.(whose做主语的定语)
2、宾语从句中的插入语常见形式
1)特殊疑问词+doyouthink(believe,suppose,say…)
Whodoyouthinkisthebeststudentinourclass?
Whodoyouthinkcananswerthequestion?
Whatdoyousupposehappentoher?
Whattimedoyouthinktomwillcomehere?
2)插入语还有youthink/expect等
Giveittowhoeveryouthinkcandotheworkwell.
3、连接词的对称
Ittooktheteacherafewdaystorememberwhowaswhointheclass.
4、That可以作except,in,besides,but的宾语,不可充当其它介词的宾语,inthat意为“在于(因为)”butthat意为“要不是(只是)”exceptthat意为“除了”
Thesuitfittedhimwellexceptthatthecolorisalittlebrighter.
其它介词后面需要用that从句作宾语,必须用it作形式宾语。
YoumaydependonitthatIwillalwayshelpthem.
5、宾语从句中的否定转移
主语是第一人称I/we。
1)将think,believe,suppose,expect,fancy,imagine,consider,expect,guess,reckon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。
 IdontthinkIknowyou. 我想我并不认识你。
 Idontbelievehewillcome. 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。
 Ihopeyouwerentill.我想你没有生病吧。
2)如果think,believe,suppose,expect,fancy,imagine,consider,expect,guess,reckon等动词前有副词或表示强调的do,does,did或同其它词构成并列谓语,或不以现在时出现,或用在插入语中,这时候不用否定转移。
Ireallyexpectshedidn’tsaythattohim.
我希望她不对他说那件事。
Ithinkandhopethathewon’tbedeceivedbytheman.
我认为他希望他不会被那个人欺骗。
3)在think,believe,suppose,expect,fancy,imagine,consider,expect,guess,reckon等此类动词后,在简略回答中,用so替代前面肯定的宾语从句;若替代一个否定的宾语从句,用not或not…so替代前文整个句子。
---Ibelievewe’vemetsomewherebefore.(我认为我们从前在哪里见过)
---no,Idon’tthinkso.(没有,我想我们以前没有见过)
----doyouthinkit’sgoingtorainovertheweekend?(你认为这周末会下雨吗?)
----Ibelievenot.(我认为不会)
4)将seem,appear等后的从句的否定转移到前面。
 Itdoesntseemthattheyknowwheretogo.
 看来他们不知道往哪去。
 Itdoesntappearthatwellhaveasunnydaytomorrow.
 看来我们明天不会碰上好天气。
5)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。
 Idontrememberhavingeverseensuchaman. 
 我记得从未见过这样一个人。(not否定动名词短语having…)
 Itsnotaplacewhereanyonewouldexpecttoseestrange
charactersonthestreet.
 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。)
6)有时状语或状语从句中否定可以转移到谓语动词前。
 Theantisnotgatheringthisforitselfalone. (否定状语) 蚂蚁不只是为自己采食。
HewasnotreadytobelievesomethingjustbecauseAristotlesaidso.
(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。
Shehadnotbeenmarriedmanyweekswhenthatmansyoungerbrothersawherandwasstruckbyherbeauty. 
(否定状语manyweeks) 
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。
6、宾语从句还可以用在某些形容词的后面,如:sure,glad,certain,sorry,afraid,worried,anxious,aware,confident,convinced,proud,surprised,thankful,ashamed,disappointed,annoyed,pleased,hurt,satisfied,content…
Iamsurethathewillcomeheretomorrow.
Theteacherwaspleasedthathisstudentshadpassedtheexam.
特别提示:
besure/certain…表示“确信或肯定……”后边从句的连词用that,但benotsure/certain后边从句的连词用if或whether。
Areyoucertainthatyou’llgetthereotime?
I’mnotsureif/whetherhisworkhasbeenfinished?
7、有些句子连词较多,应分清各自的功能
Itiswellknownthatwhat,whenandhowapersoneatscauseschangesinthebody.(that为itiswellknownthat这一结构的连词,what,whenandhow为主语从句的连词)
Tomwassoontoldwhywhathaddonewasnotnecessary.
(why是宾语从句的连词,而what是why从句中的连词)
常见错误分析
1.误:Thequestionisiftheycanworkoutthedifficultmathproblem.
正:Thequestioniswhethertheycanworkoutthedifficultmathproblem.
[点拨]:引导主语从句、表语从句时,常用whether不用if。又如:
WhetherTomgoeswithusmakesnodifference.
Whatthedoctorreallydoubtsiswhethermymotherwillrecoverfromtheseriousillness.
2.误:Thathesaidsurprisedallofus.
正:Whathesaidsurprisedallofus.
[点拨]:what引导主语从句并在主语从句中作said的宾语。当that引导主语从句时,不作句子成份,只起连接作用。
3.误:Ibelievenomatterwhathesays.
正:Ibelievewhateverhesays.
[点拨]:whatever在这里引导宾语从句,nomatterwhat只能引导状语从句。
4.误:Heaskedhowmuchshouldhepaythedoctor.
正:Heaskedhowmuchheshouldpaythedoctor.
[点拨]:一般来说,宾语从句的语序是陈述句语序。
5.误:Wholeavestheroomlastshouldlockthedoor.
正:Whoeverleavestheroomlastshouldlockthedoor.
[点拨]:who可以引导主语从句,但往往具有疑问的意义;而whoever则没有疑问的意义,相当于anyonewho。
6.误:Hewantstobecomeafriendofwhomeversharesthesameinterest.
正:Hewantstobecomeafriendofwhoeversharesthesameinterest.
[点拨]:whoever引导宾语从句并在从句中作主语,故不能用whomever。
7.误:Italldependsoniftheywillsupportus.
正:Italldependsonwhethertheywillsupportus.
[点拨]:theywillsupportus在句中作dependson的宾语,故用whether,而不用if引导。
8.误:Thereasonwhyhedidn’tcomeisbecausehismotherwasill.
正:Thereasonwhyhedidn’tcomeisthathismotherwasill.
[点拨]:Thereasonwhy…is…句型中,应用that引导表语从句,表示“……的原因是……”。不能用because引导。
9.误:Wedidn’tknowifornotshewasreadytostartwork.
正:Wedidn’tknowwhetherornotshewasreadytostartwork.
[点拨]:whether引导宾语从句时可以和ornot连用,而if则不能。
10.误:HeisfamousasanEnglishteacheriswellknown.
正:ThatheisfamousasanEnglishteacheriswellknown.
[点拨]:that引导主语从句时不能省略。
11.误:Thatreallyinterestedthechildrenwashowtousethecomputer.
正:Whatreallyinterestedthechildrenwashowtousethecomputer.
[点拨]:what引导主语从句在从句中作主语,而that引导主语从句时,不作句子成分,也没有任何含义。
12.误:Themanaskedhissonwherehefoundhisglasses.
正:Themanaskedhissonwherehehadfoundhisglasses.
[点拨]:宾语从句中动词find的动作是在主句动词ask之前发生的,因此要用过去完成时来表达。
13.误:Allwhattheyneedisenoughtimetopreparefortheexamination.
正:Allthattheyneedisenoughtimetopreparefortheexamination.
正:Whattheyneedisenoughtimetopreparefortheexamination.
[点拨]:allwhat一般不连用。Allthat…结构中,that(不能用Which)引导定语从句,修饰先行词all。what引导主语从句。

牛津高中英语语法复习:名词性从句


牛津高中英语语法复习:名词性从句
名词性从句相当于名词,可分别作主句的主语、表语、宾语和同位语。因此,名词性从句厅分为主语从句、表语从句、宾语从句和同位从句。
(一)引导名词性从句的连接词
1、连接代词:who,whose,whom,what,which。有词义,在从句中担任成分,如主语、表语、宾语、或定语等。
2、连接副词:when,where,why,how。有词义,在从句中担任成分,作状语。
3、连接词:that,whether,if,asif。that无词义,在从句中不担任成分,有时可省略;if(whether),asif虽有词义,但在从句中不担任成分。
注意:连接代词与连接副词在句中不再是疑问句,因而从句中谓语不用疑问式。连接代词与连接副词在从句充当句子成分,连接词whether和if(是否),asif(好象)在从句中不充当句子成分,只起连接作用。根据句义,如果连接代词与连接副词,whether、if和asif都用不上时,才用that作连接词(that本身无任何含义)。
(二)主语从句
1、主语从句在复合句作主语。
e.g.Whowillgoisnotimportant.
2、用it作形式主语,主语从句放在句末。
e.g.Itdoesn’tmattersomuchwhetheryouwillcomeornot.
3、that引导主语从句时,不能省略。
e.g.Thathesuddenlyfellilllastweekmadeussurprised.
(三)表语从句
1、表语从句在复合句中作表语,位于系动词之后。
e.g.Thequestionwaswhocouldgothere.
2、引导表语从句的连接词that有时可省去。
e.g.Myideais(that)wecangetmorecomradestohelpinthework.
(四)宾语从句
1、宾语从句在复合句中作宾语。引导宾语从句的连词that一般可省略。
e.g.Ihope(that)everythingisallright.
2、介词之后的宾语从句,不可用which或if连接,要分别用what或whether。
e.g.I’minterestedinwhetheryou’vefinishedthework..
I’minterestedinwhatyou’vesaid.
3、whether与if都可以引导宾语从句,常可互换。但下面情况不能互换。
①宾语从句是否定句时,只用if,不用whether。
e.g.Iwonderifitdoesn’train.
②用if会引起误解,就要用whether。
e.g.Pleaseletmeknowwhetheryouwanttogo.(此句如果把whether改成if,容易当成条件句理解)
③宾语从句中的whether与ornot直接连用,就不能换成if;不直接连用,可换。
e.g.Idon’tknowwhetherornotthereportistrue.
Idon’tknowwhether/ifthereportistrueornot.
④介词后的宾语从句要用whether引导。whether可与不定式连用。whether也可引导主语从句、表语从句、同位语从句,还可引导让步状语从句,以上均不能换成if。但引导条件从句时,只能用if,而不能用whether。
e.g.Itdependsonwhetherwehaveenoughtime.
Theydon’tknowwhethertogothere.
Pleasecometoseemeifyouhavetime.
(五)同位语从句
同位语从句在句中作某一名词的同位语,一般位于该名词(如:news,fact,idea,suggestion,promise等)之后,说明该名词的具体内容。
e.g.Ihavenoideawhenhewillbeback.
Thefactthathehadnotsaidanythingsurprisedeverybody.

2011高考英语备考(考点聚焦+名题导解)名词性从句

一、考点聚焦
1、名词性从句中连接词的运用
名词性从句中的连接词有连词that/whether/asif,连接代词what/who/which/whose/whatever/whoever/whomever/whichever,连接副词where/when/why/how/wherever/whenever。
(1)that的用法。[ks5u.com]
①主语从句、表语从句、同位语从句中用that但不能省略。如:
ThattheyaregoodatEnglishisknowntousall.
Theproblemisthatwedon’thaveenoughmoney.
SheexpressedthehopethattheywouldcometoChinaoneday.
②宾语从句中的连接词that有时可省有时又不可省,在以下几种情况中that不能省略:(A)当that从句和主句谓语动词之间有插入词语或者从句主语之间有插入语时,that不可省略;(B)当that从句与另一名词性从句并列作宾语时,that不能省;(C)当that作介词宾语时,that不可省掉。如:
Hejudgedthat,becausehewasachild,hedidnotunderstand
wine
Everyoneknewwhathappenedandthatshewasworried.
Thereasonliesinthatsheworksharderthantheothersdo.
③that从句作主语和宾语时,可以用it来替换成以下几种结构表达。
(A)Itisclear/certain/likely/true/surprisingthat…(B)Itisapity/shame/goodidea/nowonderthat...(C)Itissaid/reported/believed/known/thought/suggestedthat…(D)Itseems/happensthat。如:
IthappenedthatIwentoutlastnight.
ItissaidthatChinawillwinintheWorldCup.
④that和what的区别。
that引导名词性从句时,在主从句中不以当任何句子成分,也没有任何含义;而what引导名词性从句时,在主从句中都要充当一定的句子成分,what可以分解成定语从句中的先行词+关系代词即常说的先行词+that。如:
It’sshamethathehasmadesuchamistake.Dowhathesays.
⑤同位语从句与定语从句中that的区别。
同位语从句中的连词that只起连接作用,在从句中不担当任何句子成分;而定语从句中的关系代词that在句中做宾语或主语,宾语与先行词有修饰关系。如果句子是同位语从句,就应用连词that而不能用which.同位语从句一般放在表具体含义的名词后解释名词的含义或内容,如以下名词:news、fact、suggestion、truth、plan、belief、doubt、possibility、idea等,而定语从句只是对先行词的限定和修饰。如:
TheyexpressedthehopethattheywouldcometovisitChinaagain.(同位语从句)
ThehopesheexpressedisthattheywouldcometovisitChinaagain.(定语从句)
(2)whether和if的用法。
①whether和if在宾语从句中可以互换,但是作介词宾语时连接词一般用whether。如:
Italldependsonwhethertheywillcomeback.
②后面直接跟ornot时用whether。如:
Ididn’tknowwhetherornothehadarrivedinWuhan.
③主语从句表语从句中只能用whether。如:
Whetherthemeetingwillbeputoffhasnotbeendecidedyet.
Thequestioniswhethertheyhavesomuchmoney.
④whether可以引导同位语从句,用以说明前面的名词的内容,if不能。如:
Weoughttodiscusscarefullythequestionwhetherwecando
itornot.
⑤whether常与or连用表示一种选择,if不能这样用;whether也可与动词不定式连用但if不能。如:
Thequestionofwhethertheyaremaleorfemaleisnotimpor-
tant.
Ihavenotdecidedwhethertogoornot.
⑥间接引语位于句首时或者是间接引语提前时用whether不用if。如:
Thankyou,butwhetherI’llbefreeI’mnotsureatthemoment.
⑦whether可引导一个让步状语从句表示“不管”、“无论”,而if不能。如:
Whetherhecomesornot,wewillbeginourpartyontime.
(3)疑问词+ever和nomatter+疑问词的区别。
①疑问词+ever可引导名词性从句,在主从句中要充当一定的部分。如:
Whoeverbreakstherulemustbepunished.
Youcanchoosewhateveryoulikeintheshop.
②疑问词+ever还可引导让步状语从句。如:
Whoeverbreakstherule,hemustbepunished,
Whateveryoudo,youmustdoitwell.
③nomatter+疑问词只能引导让步状语从句。如:
Nomatterwhatyoudo,youmustdoitwell.
Nomatterwhobreakstherule,hemustbepunished.
(4)when和where引导的同位语从句与定语从句的区别。
when和where前面的名词若是表示时间、地点的名词,则when和where引导的是定语从句,否则则为同位语从句。如:
Theyputforwardthequestionwheretheycouldgetthemoney.
Thisistheplacewheretheaccidenthappened.
2、名词性从句中主句和从句的时态一致
(1)宾语从句中主句和从句的时态保持一致,但如果从句中表示提示的是客观现象,虽然主句是过去时态,从句仍用一般现在时。如:
Hello,Ididn’tknowyouwereinLondon.Howlonghaveyoubeenhere?
Theteachertoldusthatlighttravelsataveryhighspeed.
(2)主语从句作主语相当于单数第三人称作主语,谓语动词用单数,如果由and连接两个或两个以上的主语从句作主语时,谓语动词用复数;由两个或多个连接词引导一个主语从句,谓语动词用单数。如:
Whenthemeetingwillbeginhasnotbeendecidedyet.
Whentheywillstartandwheretheygohavenotbeendecidedyet.
Whenandwherethemeetingwillbeginhasnotbeendecided.
3、名词性从句的词序
名词性从句在句中要用陈述句语序。如:
Heaskedmewhatwasthematterwithme.
We’veheardthenewsthatwe’llmoveintothenewhouse.
Whateveryousaywillinterestusall.
二、精典名题导解
选择填空
1.Acomputercanonlydo________youhaveinstructedittodo.
A.howB.afterC.whatD.when
解析:答案为C。本题考查的是名词性从句作宾语的用法。此句的引导词既作连词又在宾语从句中充当一成分,故what最合适。
2.—IdrovetoZhuhaifortheairshowlastweek..
—Isthat_________youhadafewdaysoff?(NMET99)
A.whyB.whenC.whatD.where
解析:答案为A。此题考查的是从句的用法。根据题意“我上周开车去珠海看航空展去了。”下面一句接着问:“那就是你为什么离开的原因吗?”故用why引导表语从句表示原因。
3.Ihate__________whenpeopetalkwiththeirmouthsfull.(NMET98)
A.itB.thatC.theseD.them
解析:答案为A。本题考查的是形式宾语的用法。题意为“我讨厌人们谈话时嘴里塞满东西”。该空白处没有任何含义,而且已经用了when连接该宾语从句,所以此处只填一个形式宾语it。
4.IthinkFatherwouldliketoknowI’vebeenuptosofar,soIdecidetosendhimaquicknote.
A.whichB.whyC.whatD.how
解析:答案为C。考查宾语从句连词用法,由结构sb.beuptosth.可知,应选what作介词to的宾语。
5.Wecannotfigureoutquiteanumberofinsects,birds,andanimalsaredyingout.
A.thatB.asC.whyD.when
解析:答案为C。本题考查宾语从句知识,figureout为及物动词,故此句为宾语从句,从句意得知连词在从句中作原因状语,故选why.
6.AfterYangLiweisucceededincirclingtheearth,ourastronautsdesiredoiswalkinspace.
A.whereB.whatC.thatD.how
解析:答案为B。此题句子为时间状语从句,全主句的主语是由主语从句来充当的,并且主语从句中不定式动词do缺少宾语,故选what。

名词性从句中的连接词有连词that/whether/asif,连接代词what/who/which/whose/whatever/whoever/whomever/whichever,连接副词where/when/why/how/wherever/whenever。

⑥间接引语位于句首时或者是间接引语提前时用whether不用if。如:

⑦whether可引导一个让步状语从句表示“不管”、“无论”,而if不能。如:

when和where前面的名词若是表示时间、地点的名词,则when和where引导的是定语从句,否则则为同位语从句。如:
Theyputforwardthequestionwheretheycouldgetthemoney.
Thisistheplacewheretheaccidenthappened.
2、名词性从句中主句和从句的时态一致
(1)宾语从句中主句和从句的时态保持一致,但如果从句中表示提示的是客观现象,虽然主句是过去时态,从句仍用一般现在时。如:
Hello,Ididn’tknowyouwereinLondon.Howlonghaveyoubeenhere?
Theteachertoldusthatlighttravelsataveryhighspeed.
(2)主语从句作主语相当于单数第三人称作主语,谓语动词用单数,如果由and连接两个或两个以上的主语从句作主语时,谓语动词用复数;由两个或多个连接词引导一个主语从句,谓语动词用单数。如:
Whenthemeetingwillbeginhasnotbeendecidedyet.
Whentheywillstartandwheretheygohavenotbeendecidedyet.
Whenandwherethemeetingwillbeginhasnotbeendecided.
3、名词性从句的词序
名词性从句在句中要用陈述句语序。如:
Heaskedmewhatwasthematterwithme.
We’veheardthenewsthatwe’llmoveintothenewhouse.
Whateveryousaywillinterestusall.
二、精典名题导解
选择填空
1.Acomputercanonlydo________youhaveinstructedittodo.
A.howB.afterC.whatD.when
解析:答案为C。本题考查的是名词性从句作宾语的用法。此句的引导词既作连词又在宾语从句中充当一成分,故what最合适。
2.—IdrovetoZhuhaifortheairshowlastweek..
—Isthat_________youhadafewdaysoff?(NMET99)
A.whyB.whenC.whatD.where
解析:答案为A。此题考查的是从句的用法。根据题意“我上周开车去珠海看航空展去了。”下面一句接着问:“那就是你为什么离开的原因吗?”故用why引导表语从句表示原因。
3.Ihate__________whenpeopetalkwiththeirmouthsfull.(NMET98)
A.itB.thatC.theseD.them
解析:答案为A。本题考查的是形式宾语的用法。题意为“我讨厌人们谈话时嘴里塞满东西”。该空白处没有任何含义,而且已经用了when连接该宾语从句,所以此处只填一个形式宾语it。
4.IthinkFatherwouldliketoknowI’vebeenuptosofar,soIdecidetosendhimaquicknote.
A.whichB.whyC.whatD.how
解析:答案为C。考查宾语从句连词用法,由结构sb.beuptosth.可知,应选what作介词to的宾语。
5.Wecannotfigureoutquiteanumberofinsects,birds,andanimalsaredyingout.
A.thatB.asC.whyD.when
解析:答案为C。本题考查宾语从句知识,figureout为及物动词,故此句为宾语从句,从句意得知连词在从句中作原因状语,故选why.
6.AfterYangLiweisucceededincirclingtheearth,ourastronautsdesiredoiswalkinspace.
A.whereB.whatC.thatD.how
解析:答案为B。此题句子为时间状语从句,全主句的主语是由主语从句来充当的,并且主语从句中不定式动词do缺少宾语,故选what。
