名词性从句知识归纳
名词性从句是指在句子中相当于名词的从句，主要包括主语从句、宾语从句、表语从句和同位语从句。名词性从句不是修饰性从句，而是复合句中的主干。
e.g.Thattheboyfailedagainintheexam disappointedhismother.（主语从句）
Iknow thatheiswritinghiscompositioninhisroom.（宾语从句）
Thequestionis howwecanfinishitontime.（表语从句）
Thefact thatsomeChinesearestillpoor isreallyagreatproblem.（同位语从句）
Iwanttoknowwhetherhewillseethefilmornot.
(2)介词宾语从句要用whethere.g.Idon’tcareabout whetheryouhavemoneyornot.
(3)that引导的宾语从句只能放于in,except,besides和but四个介词后
e.g.TheSwedestoodstill,except thathislipsmovedslightly.
3.转移否定---当主句是I/Wethink(believe,consider,expect,suppose,guess,imagine)时，其后的宾语从句如果是否定形式，常把从句中的否定词not转移到主句中。
e.g.Idon’tsuppose(that)itishisfault,isit?
4.时态问题---宾语从句的时态常受到主句时态影响，若主句是现在时或将来时，从句可用任何所需要的时态；若主句是过去时态，从句一般用过去的某种形式，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，则从句仍用一般现在时态。
e.g.Iknow(that)hedidn’ttellyouwhathewouldcomethen.
Webelieved thathehadearnedenoughmoneytobuildahouse.
Theteachertoldus thatTomhadleftusforAmerica.
Theteachertoldus thatthesunrisesintheeast.
5.一种特殊类型的宾语从句---在这种句子里doyouthink等意为插入语，但实为主句，因此余下部分应用陈述语序
余下部分?
e.g.Where doyouguess ourartfestivalistobeheld?
Who doyouthink thepublicmightchooseastheirfavoritesingerthisyear?
二、主语从句---位于句首，常用it做形式主语
e.g.Thathewillcomeandhelpyou iscertain.(that不充当从句内的任何成分，不可省略)
)

(4)
e.g.
2.it
e.g.
解题方法：将itis/was…that去掉，看余下部分是否完整，若完整即为强调句式；反之为it作形式主语。
三、表语从句---系动词后（常见系动词：be,look,remain,seem,appear等）
e.g.Theproblemis that theycan’tgethereearlyenough.
Thequestionis whetherwecanreducethecostoftheproduct.
Itlooks asifit’sgoingtorain.
Thequestionis who(whichofyou)willbethenextspeaker.
Whathewantstogetis whateveryouhave.
Thisis whereourproblemlies.
Thatis whyhedidn’t cometothemeeting.
四、同位语从句---抽象名词后（从句对抽象名词进行补充说明或解释说明抽象名词的内容）
e.g.Thenews thathehadlandedonthemoon spreadallovertheworld.
Thethoughtcametohim thatMaryhadprobablyfallenill.
Hemustanswerthequestion whetherheagreestoitornot.
Ihavenoidea whenhewillcomebackhome.
名词性从句高考趋势与考察重点
一、语序问题---名词性从句内部一律使用陈述语序
注意以下句子：
e.g.Idon’tknow whatisthematterwithhim.
Ihavenoidea whatwasthematterwithhim.
Couldyoutellus whatwaswrong/thetroublewithhimyesterday?
二、从句中的虚拟语气问题
1.主语从句：
(1)Itisimportant/natural/necessary/essential/strange/that…(should)do…
(2)Itissuggested/advised/deman ded/ordered/requestedthat…(should)do…
e.g.Itisimportantthateverystudent(should)learn aforeignlanguage.
2.
【insist），
3.为on
4.释on
1.doubt
后面用
e.g.
Ihave
2.sure
e.g.
Areyousure thatyou’vefoundtheanswertothisquestion.
I’mnotsure whe therI’vefoundtheanswertothisquestion.
3.主语是reason时，表语要用that引导而不是because：
e.g.Thereasonwhyhewaslatewas thathemissedthetrainbyoneminutethismorning.
4.what和that---that在从句中不充当成分，不含疑问意义，而what在从句中充当主语、宾语或表语，且含有疑问意义。
e.g.ThatTomfelloffhischairbyaccident gottheclassmateslaughing.
WhatTomlearnedinuniversity helpshimalotinhisjob.
=Allthat Tomlearnedinuniversityhelpshimalotinhisjob.
5.连接词wh-和wh-ever选择---前者表示一个特指概念，引导的名词性从句含有疑问意义；
后者表示一个泛指概念，意为“任何……”，引导的名词性从句不含有疑问意义，相当于名词后加一个定语从句。
e.g.Itwasamatterof whowouldtaketheposition.
Sarahhopestobecomeafriendof whoeversharesherinterests.
(=anyonewhosharesherinterests.)
Theywilldo whateverhewantsthemtodo.(=anythingthathewantsthemtodo)
6.This/Thatiswhy…和This/Thatisbecause…
e.g.ThereasonwhyIcamelateisthatmycarbrokedownonthehalfway.
→Hecame late.That’s becausehiscarbrokedown.
→Hiscarbrokedownonthehalfway.That’s whyhecamelate.
7.几个特殊句型之间的转换
Thesuggestion thatwediscusstheproblemalloveragainisagoodone.
Thesuggestion thathegaveatthemeetingwasagoodone.
【名词性从句的解题思路】：高考中考查名词性从句时，经常考查连接词的选用。解题时应先判断从句的类型，然后判断从句是否缺少成分以及意义是否完整，最后根据引导名词性从句的连词的特点确定特定的连接词。
高中英语语法定语从句总复习 郴州资兴三中李俊才 定义：用来说明主句中某一名词或代词（有时也可说明整个主句或主句中一部分）而起定语作用的句子叫 作定语从句。 一、关系带词引导的定语从句 1. 关系代词用来指代先行词是人或物的名词或代词 句子成分用于限制从句或非限制性从句只用于限制性从句 代替人代替物代替人或物主语Who which 主语Whom which that 宾语Whose (=of whom) Whose (=of which) that 例１：This is the detective who came from London. 例２：The book which I am reading is written by Tomas Hardy. ２．关系代词的用法 (1) 如果先行词是all, much, anything, something, nothing, everything, little, none等不定代词，关系代词一般只用that，不用which。例如： All the people that are burst into tears.（所有人都迸出眼泪。） (2) 如果先行词被形容词最高级以及first, last, any, only, few, most, no, some, very等词修饰，关系代词常用that,不用which, who，或whom。 (3) 非限制性定语从句中，不能用关系代词that,作宾语用的关系代词也不能省略。 There are about seven million people taking part in the election, most of whom、are well educated. (4) which还有一种特殊用法，它可以引导从句修饰前面的整个主句，代替主句所表示的整体概念或部分 概念。在这种从句中，which可以作主语，也可以作宾语或表语，多数情况下意思是与and this 相似，并可以指人。例如： He succeeded in the competition, which made his parents very happy. (5) that可指人或物，在从句中作表语，（指人作主语时多用who）仅用于限制性定语从句中。

英语语法讲解之定语从句 时间：2016-08-12作者：来源：学习方法网 一．几个基本概念 1.定语从句的定义：用作定语的从句叫定语从句。 2.先行词：被定语从句所修饰的名词或代词。 3.定语从句的位置：紧跟先行词(名词或代词)之后。 4.引导词：引导定语从句的词(包括关系代词和关系副词)。 ﹙1﹚关系代词：that/who/whom/which/as ﹙2﹚关系副词：when/where/why 5.引导词的位置：位于定语从句之前(先行词之后)。【as除外】 6.引导词的功能(作用)： ﹙1﹚连接先行词和定语从句。 ﹙2﹚在定语从句中充当一定的成分(关系代词充当主语或宾语，关系副词充当状语)。 7.定语从句的类型： ﹙1﹚限定性定语从句(主句和定语从句之间无逗号)。 ①直接由引导词引导定语从句 The man who you’re talking to is my friend. ②由介词+关系代词(whom/which)引导 The man to whom you’re talking is my friend. I need a pen with which I can write a letter.
=I need a piece of paper on which I can write a letter. 介词的选用可根据从句中的相关词组确定，该介词通常可以放在关系代词之前，也可放在从句之尾。例如： The man (who/whom/that) I talked about at the meeting is from Beijing University. =The man about whom I talked at the meeting is from Beijing University.

There is an apple tree standing at the gate，on which are many apples. This is the man to whom I gave the book. ③由“代词/名词+of+whom/which”或“of which/ whom +名词/代词”(先行词指 人用whom，指物用which)引导。One，some，any，none，all，both，several，many，most，neither，either等词、数词、分数或百分比与of whom或of which连用。 He has five children，two of whom are abroad. (比较：He has five children，and two of them are abroad.) We have three books，none of which is/are interesting. (比较：We have three books，but none of them is/are interesting.) 除why和that不能引导非限定性定语从句外，其余引导词都可以，用法同限定性定语从句一样。但要注意以下区别。

【考点五】语法考点归纳5（定语从句、名词性从句） 定语从句考点归纳 1．高考对定语从句的考查集中体现在关系词的选择上，包括关系代词和关系副词。关系代词只有6个，即：that，which，who，whom，whose，as，关系副词只有3个，即：when，where，why。 2．选择关系代词和关系副词的方法：由于关系词既有连接作用又有替代作用和成分作用（引导定语从句并在从句中替代先行项/词而且还充当一定的成分），所以在选择关系词时有一个很简单的方法。把先行项/词还原到从句中，看看该用什么关系词来替代。例如： I visited a scientist ______ name is known all over the country. 把先行词a scientist还原到从句中就是：the scientist’s name is known all over the country 可见从句中缺定语，这里该填whose。又如：The school _____ I studied for only two years was three kilometers away. 把先行词the school还原到从句中就构成这样一个简单句：I studied for two years in the school. “in the school”是一个表示地点的介词短语，在从句中作状语，要用where（=in which）来替代。 3．注意关系代词as和which引导非限定性定语从句的区别：as引导的非限定性定语从句可以置于句首，而which 引导的非限定性定语从句只能位于句中或句尾。 4．注意掌握只用关系代替that、只用关系代词which的常见的几种情况，以及“介词+关系代词”引导的定语从句。 考点精析 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, 在从句中所起的作用如下: Is he the man who/that wants to see you 他就是你想见的人吗(who/that在从句中作主语) Hs 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 shoes car had broken down. 那人的车坏了, 大家都跑过去帮忙 Please pass me the book whose (of which) cover is green. 请递给我那本绿皮的. (3)Which, that它们所代替的先行词是指代事物的名词或代词, 在从句中可作主语, 宾语等. 例如: A prosperity 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) 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, there, why 关系副词when, where, why的含义相当于“介词+which”结构, 因此常常和“介词+which”结构交替使用. 例如: There are occasions when (on which) one must yield.
定语从句专题复习 定语从句（AttributiveClauses）在句中做定语，修饰一个名词或代词，被修饰的名词，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(一般指人),that（指人或物）,which(指物)等。 关系副词有：when（时间）,where(地点),why（原因）等。 （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。 ①who,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： Ishethemanwho/that wantstosee you 他就是你想见的人吗（who/that在从句中作主语） Heistheman(whom/that)I saw yesterday. 他就是我昨天见的那个人。（whom/who/that在从句中作saw的宾语,可以省略） ②whose用来指人或物，（只用作定语，若指物，它还可以同ofwhich互换），例如：Theyrushedovertohelpthemanwhosecarhadbrokendown. 那人车坏了，大家都跑过去帮忙。 Pleasepassmethebookwhose/ofwhichcover（封面）isgreen. 请递给我那本绿皮的书。 ③which,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：Rosalikesmusicthat/whichisquiteandgentle.（which/that在句中作宾语） Thisisthebook(that/which)I'mlookingfor.（which/that在句中作lookfor的宾语） （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。 ①when,where,why 关系副词when,where,why的含义相当于“介词+which”结构，因此常常和“介词+which”结构交替使用，例如： Doyouremembertheday when Isawyou(你还记得我见到你的那一天吗) Beijingistheplace where（inwhich）Iwasborn.北京是我的出生地。 Isthisthereason why（forwhich）herefusedouroffer 这就是他拒绝我们帮助他的理由吗 ②that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： Hisfatherdiedtheyear（that/when/inwhich）hewasborn. 他父亲在他出生那年逝世了。 Heisunlikelytofindtheplace（that/where/inwhich）helivedfortyyearsago. 他不大可能找到他四十年前居住过的地方。 （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：
中考英语状语从句知识点汇总 一、引导词的选择： 1.时间状语从句 1).由when 、while、as（当……时候）引导的时间状语从句。When jack got home , his mother was cooking . 2).由after/ before (在….之后/ 前)引导的时间状语从句。 The football match played after school was over . 3).由as soon as (一…..就……)引导的时间状语从句。 I’ll ring you as soon as I reach Beijing . 4).由not….until（直到…..才…..）引导的时间状语从句。 They didn’t stop until they finished the work . 2.原因状语从句 由because 、since 、as（因为、既然、由于）引导的原因状语从句。 Since you have known about that , please tell us what to do . 3.地点状语从句 由wherever（无论在哪儿）引导的地点状语从句。

名词性从句知识点总结 在句子中起名词作用的句子叫名词性从句(Noun Clauses）。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．主语从句 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。被强调部分指人时也可用who/whom。例如： a) It is a pity that you didn’t go to see the film. 你不去看那场电影真可惜。 b) It doesn’t interest me whether you succeed or not.我对你成功与否不感兴趣。 c) It is in the morning that the murder took place.谋杀案是在早上发生的。（强调句型） d) It is John that broke the window.是John打碎的窗户。（强调句型） 2. 用it 作形式主语的结构 (1) It is ＋名词＋从句 It is a fact that …事实是… It is an honor that …非常荣幸 It is common knowledge that …是常识 (2) It is ＋形容词＋从句 It is natural that…很自然… It is strange that…奇怪的是… (3) It is ＋不及物动词＋从句 It seems that…似乎… It happened that…碰巧… It appears that…似乎… (4) It ＋过去分词＋从句 It is reported that…据报道… It has been proved that…已证实… It is said that…据说… 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）It is said /reported…结构中的主语从句不可提前。例如： 正确表达：It is said that President Jiang will visit our school next week. 错误表达：That President Jiang will visit our school next week is said. （3）It happens/occurs…结构中的主语从句不可提前。例如： 正确表达：It occurred to him that he failed in the examination. 错误表达：That he failed in the examination occurred to him. （4）It doesn’t matter how/whether …结构中的主语从句不可提前。例如： 正确表达：It doesn’t matter whether he is wrong or not.
2016年必考英语语法——限定性定语从句 1.that即可代表事物也可代表人，which代表事物；它们在从句中作主语或宾语，that 在从句中作宾语时常可省略关系词，which在从句中作宾语则不能省略。而且，如果which在从句中作“不及物动词+介词”的介词的宾语，注意介词不要丢掉，而且介词总是放在关系代词which的前边，但有的则放在它原来的位置 2.which作宾语时，根据先行词与定语从句之间的语义关系，先行词与which之间的介词不能丢 3.代表物时多用which，但在带有下列词的句子中用that而不用which，这些词包括all, anything, much等，这时的that常被省略 4.who和whom引导的从句用来修饰人，分别作从句中的主语和宾语，whom作宾语时，要注意它可以作动词的宾语也可以作介词的宾语 5.where是关系副词，用来表示地点的定语从句 6.when引导定语从句表示时间 〔注〕值得一提的是，表示时间“time"一词的定语从句只用when引导，有时不用任何关系代词，当然也不用that引导 By the time you arrive in London, we will have stayed there for two weeks. I still remember the first time I met her. Each time he goes to besiness trip, he brings a lot of living necessities, such as towers, soap, toothbrush etc. 7.whose是关系代词，修饰名词作定语，相当于所修饰成分的前置所有格
名词性从句知识归纳 名词性从句是指在句子中相当于名词的从句，主要包括主语从句、宾语从句、表语从句和同位语从句。名词性从句不是修饰性从句，而是复合句中的主干。 e.g. That the boy failed again in the exam disappointed his mother. （主语从句） I know that he is writing his composition in his room. （宾语从句） The question is how we can finish it on time. （表语从句） The fact that some Chinese are still poor is really a great problem. （同位语从句） 一、宾语从句---及物动词、介词、部分形容词（certain, sure, glad, afraid, frightened, happy, pleased, sad, sorry, surprised, upset, satisfied等）后 e.g. I believe (that) he is honest. (that不充当从句内的任何成分，一般情况可省略) I’m glad that you are satisfied with your job. (that不充当从句内的任何成分) He doesn’t care if/whether it isn’t a fine day. (if/whether不充当从句内的任何成分) Please tell me what you want. (what充当从句内的宾语) She always thinks of how she can work well. (how充当从句内的状语) I don’t believe whatever he said.(whatever充当从句内的宾语，意为“任何事”) I’ll take whoever wants to go. (whoever从当从句内的主语，意为“任何人”)【宾语从句要点拓展】1. that引导宾语从句时一般可以省略，若由and或or连接两个宾语从句时，第一个从句中的that可以省略，而第二个分句前的that不可省略。 e.g. He told me (that) they could not decide what to do and that they asked my advice. 2. whether和if引导宾语从句一般可以互换使用，但以下情况只能使用whether
高中英语---定语从句 一定义及相关术语 1．定语从句：修饰某一名词或代词的从句叫定语从句。定语从句一般紧跟在它所修饰的词之后。 2．先行词：被定语从句修饰的词叫先行词。 3．关系词：引导定语从句的词叫关系词。关系词有关系代词和关系副词。关系代词有that, which, who, whom, whose, as等；关系副词有when, where, why等 关系词在定语从句中有三大作用 1. 连接作用——连接先行词和定语从句。 2. 替代作用——在定语从句中替代从句所修饰的先行词。 3. 成分作用——在定语从句中作主语、宾语、定语或状语。 The man who is shaking hands with my father is a policeman. 二关系代词引导的定语从句 引导定语从句的关系代词主要有who, whom, whose, which, that等。它们分别代替前面的先行词，并在定语从句中作主语、宾语或定语。 1. who 指人，在定语从句中作主语。 That is the teacher who teaches us physics. 2. whom 指人，在定语从句中做宾语，可省略，在口语或非正式文体中常可用who 来代替。Li Ming is just the boy (whom) I want to see. 3. which 指物，在定语从句中做主语或宾语，做宾语时常可省略。 Football is a game which is liked by most boys. 4. that 指人时，相当于who 或whom；指物时，相当于which.。在定语从句中作主语或宾语，作宾语时常可省略。 He is the man that/who lives next door. Where is the man (that/whom) I saw this morning? 、The season that/which comes after spring is summer. The dress (that/which) Ann bought doesn’t fit her very well. 5. whose 指人、物皆可，与后面的名词有所属关系，在定语从句中做定语。 I visited a scientist whose name is known all over the country.
