名词性从句解题

I 定义：在句子中起名词作用的句子就叫名词性从句。

II 分类：主语从句，宾语从句，表语从句和同位语从句

III.连接词

1) 连接代词(在从句中作“主语,宾语,表语,定语”)

what(ever) / which(ever) 作主语、表语、定语

The shopkeeper did not want to sell for what he thought was not enough.(主语) Whatever I do is for you.(宾语)

The country is no longer what it used to be. (表语)

You can never imagine whatever great difficulty I had in solving the problem. (定语) who(ever) 作主语、宾语、表语

Give the job to whoever you think is equal to it. (主语)

Please give the gift to whoever you would like to give.(宾语)

whom(ever) 作宾语、表语

whose作定语

I don’t know whose book it is.

2）连接副词(在从句中作“状语”)

when(ever) / where(ver) / how(ever)

Please remind me when he said he was going. I may be in time to see him off.

I don’t know where/how he will go.

3）连接词(在从句中不作成分)

that / whether / if

That Tom was late made his mother very angry.

It is not clear whether the newly-elected president will end the conflict.

IV四类从句：

一、主语从句: 作句子主语的从句叫主语从句

That knowledge is power is known to all.

注意：

1）that引导的主语从句，只起连接句子的作用，本身没有词义，不作成分但不能省略。

2）whether 引导主语从句时，表示主语从句意义的不确定性，但有词义，作“是否”讲。

一般来说，已确定的事情由that 引导，没有确定的事情用whether 引导。

二. 宾语从句

1) 宾语从句常出现在及物动词或介词之后，有时出现在be + adj. 之后

I want to know whether he will attend the meeting.

Jiao Yulu always thought of how he could do more for the society and the people.

I’m afraid that I have made a mistake. 我恐怕犯了一个错误。

2) that 引导宾语从句通常可省。但若有几个宾语从句并列时，只有第一个that可省。

三. 表语从句：常放在系动词be, look, seem, appear, remain 等之后，在句子中作表语的从句叫表语从句

常见句型：

①It looks as if …

② It seems / appears as if …

that …

③The reason ...is that … 原因是…

④This / that is because … 这是/那是因为

This / That is why … 这就是/那就是为什么…

They all work so hard. This is because they know what they are working for.

他们工作很努力，这是因为他们知道自己为什么而工作。

They were short of experience. That was why they had to learn from practiced workers

他们缺少经验，这就是为什么它们必须向有经验的工人学习(的原因)。

四. 同位语从句

跟在抽象名词idea, news, fact , promise, hope , thought , belief , order, suggestion ,plan , doubt , explanation ,answer, chance等之后，用来表示名词所表示的具体内容。连接词that(常考)；whether 只起引导作用, 在从句中不作任何成分，不能省略。另外也可用where, when ,how 等词引导。

that引导的同位语从句与that 引导的定语从句

1）同位语修饰抽象名词，定语从句无限制

2）名词放回句中作成分为定语从句，不能放回句中作成分为同位语从句

There is much chance that Bill will recover from his injury in time for the race.

III常见考点：

1.it的特殊用法：

1）it作形式主语，常见句型有：

It + be +adj. + that

It +be + 名词词组( no wonder, an honour, a pity, no surprise) + that

It +be+ 过去分词( said, reported, expected, decided, announced) +that

eg. It is certain that she will do well in her exam

It’s no wonder that they look alike.

It is said that Mr.Green has gone to Beijing.

2) it 作形式宾语,常用在think /consider/make/find/feel/take+ it+ adj.\ n. +that\to do sth句式中

We have make it clear that anyone who breaks the law is to be punished.

You can’t take it for granted that everyone should adore you.

2. 和suggest这类词有关的从句谓语动词需用should do

动词一坚持insist 二命令order, command 四建议suggest, advise, propose,

recommend 五要求ask,demand, request, require, desire

后面的宾语从句要用虚拟语气that sb (should) do sth

当这类动词转化成名词引导主语从句，表语从句，同为语从句时从句中动词也用虚拟语气eg. I suggest that he (should) go abroad for further study.

I give him a suggestion that he go abroad for further study.

My suggestion is that he go abroad for ….

3.连接代词whoever，whatever

1)引导名词性从句

whoever = anyone who( 后的谓语用单数)

whatever= anything that

Whoever breaks the law should be punished.

Whatever we do must be in the interests of the people.

2)引导让步状语从句，相当于no matter +who/ what

Whatever you do,wherever you go,I will be right here waiting for you.

4. 辨析who 与whoever

whoever= anyone who，中心词为anyone, 而who引导名词性从句是主语从句表示的这件事作主语。Who will give us a talk is unknown.

Whoever(=anyone who) breaks the law should be punished.

5. 辨析that / what

1) that 引导名词性从句，只起连接句子的作用，本身没有词义，不作成分但不能省略。

* that 引导宾语从句通常可省。但若有几个宾语从句并列时，只有第一个that可省。

2）what 引导名词性从句，在句中作主语，宾语，定语，表语

3）all( that) = what

eg. To a highly imaginative writer, all that ( what) is required is a piece of paper and a pen.

6. 辨析“是否”whether / i f

只用whether 不用if 的情况

1）引导的从句位于句首时

2）引导表语从句

3）作介词的宾语

4）后接不定式

5）和or not 连用构成whether or not结构

和or连用，表示无论...还是, 不管...还是,是...还是

I don’t know whether you are right or wrong.

I don’t know whether you are right or not.

名词性从句的解题技巧

名词性从句的解题技巧-标准化文件发布号：（9556-EUATWK-MWUB-WUNN-INNUL-DDQTY-KII

名词性从句解题方法 <方法>——先大类后口诀法第一步：先分析出大的类别——定从/名从/状从即分析所缺部分在主句中的成分从而确定从句大的类别第二步：口诀逐一解决： (I)名词性从句。——口诀——先成分后含义 (II)定语从句。——口诀——先成分后先行词 (III)状语从句。——口诀：翻译即可例如：名词性从句的口诀执行方法是：分析引导词在从句中的成分 A 做名词性成分——what/which/who/as(+W-ever型) B 做非名词性成分 a 不做成分：that/if/whether(whether霸王原则) b 做状语成分：when/where/why/how 一旦分出AB两类，剩余的靠含义直接翻译即可解决。

例如A computer can only do _________ you have instructed it to do. (01年31题) A. how B. after C. what D. when 解：第一步：先分析出大的类别 A computer can only do中的do是及物动词，后面缺少do的对象，所以考察名词性从句问题第二步：口诀——先成分后含义从句you have instructed it to do中的do是及物动词，后面缺少do的对象，所以前面的空在后面的从句内充当名词性成分，所以可以选择的引导词就可以排除AD(因为这两个引导词在从句中是充当状语的)，而选项B是名词性从句中不存在的引导词，所以B也不对，最后就剩下一个正确选项C 如此这样一步一步下来，逐一进行排除和选择，最终总是可以直接定位到正确的答案。而这个过程应该是完全被熟化在脑中的一个过程，按部就班的操作直至正确答案自然而然的浮出水面。其他类别的题目也应该仿照此类，依次完成。 2、建立良好的做题习惯，沉稳面对每一个考验。

That; what 【答案】 C 【解析】【分析】句意：让我感到担忧的是，今天的歌星是以青少年为中心的。分析句子可知，主语从句中的谓语动词makes 缺少主语，主语从句中缺少宾语一般用what，因此选择 what 来引导主语从句；系动词 is 后面的表语从句句意完整，不缺少成分，因此选择 that 引导表语从句。分析选项可知C项符合题意，故选C。【点评】考查名词性从句，本题涉及what引导的主语从句和that引导的表语从句的应用。 2．________ is known to us all that the old scientist, for ________ life was hard in the past, still works hard in his eighties. A. As; whose B. It; whose C. As; whom D. It; whom 【答案】 D 【解析】【分析】句意：我们都知道，那位老科学家，过去生活很艰苦，到了八十多岁还在努力工作。第一空it is known to us all that…是个固定句型，意为“众所周知…”；第二空为介词+关系代词引导的定语从句，先行词the old scientist指人，作介词for的宾语，只能用whom，故选D。【点评】考查名词性从句和定语从句，本题涉及固定句式it is known to us all that…和whom引导的限制性定语从句。 3．Some people believe _______ has happened before or is happening now will repeat itself in the future.

英语《名词性从句》语法知识及英语学习方法

英语《名词性从句》语法知识及英语学习方法名词性从句一、that 从句 1、主语从句（1）that从句作主语时，常用it作形式主语，常见的句型有： It+be+形容词（obvious, true, natural, surprising,good,wonderful,funny,possible,likely,certain,probable,etc.）+that从句 It+be+名词词组（no wonder, an honor, a good thing, a pity, no surprise, etc.）+that 从句 It+be+过去分词（said, reported, thought, expected, decided, announced, arranged, etc.）+that从句（2）that可以省略，但that从句位于句首时，that不能省略。 2、宾语从句（1）常见的可以接that从句作宾语的动词有see, say, know, imagine, discover, believe, tell, show, think, consider, be sure, be afraid等。在可以接复合宾语的动词

之后，如think, make, consider等，可以用it作形式宾语。（2）That从句一般不能充当介词宾语，偶尔可作except, in 的宾语。 3、表语从句（that不可省略） 4、同位语从句连词that引导同位语从句时，应在某些抽象名词之后，如：fact, hope, desire, thought, suggestion, idea, news, problem, possibility等，对前面的名词起补充说明的作用，that在从句中不担当任何成分，不能省略。二、whether/if从句 1、在表语从句和同位语从句中只能用whether不能用if;当主语从句放于句首时，只能用whether不用if;当it作形式主语，主语从句放在句末时用whether或if 均可；discuss后引导宾语从句时，必须用whether。 2、在宾语从句中：（1）及物动词后：whether从句中不能有否定式，宾语从句为否定句时用if；if 不能与or not连用，但可以用whether or not；whether后可以加不定式。（2）介词后：只能用whether,不用if。三、特殊疑问词引导的从句 1、主语从句：特殊疑问词引导主语从句时，常用it作形式主语。 2、宾语从句（1）常见的能接特殊疑问词引导的宾语从句的动词有see, tell, ask, answer, know, decide, find out, imagine, suggest, doubt, wonder, show, discuss, understand, inform, advise等。（2）作介词宾语。 3、同位语从句、表语从句

(完整版)高考英语【名词性从句】

专题十名词性从句第一节基本知识与基本概念【什么是名词性从句？】顾名思义，主语从句在句子中作主语。有时本身出现在主语的位置上，也有时出于句子结构的考虑退到句子的尾部，前面用形式主语it代替。从句作主语时，谓语动词一般为单数形式。如: What I saw was beyond any verbal description. That his hair was turning grey worried him a bit. Why the company denied the contract is still unknown. When and where the government will build a city square is under discussion. It is pretty annoying that a small part of the machine is missing. It remains to be seen whether the new novel will be well received. 【宾语从句】在句子中作宾语的从句就是宾语从句。由于这是同学们接触比较早的一种从句，应该问题不大。所以在近年的高考题中，以宾语从句的知识作为考点的题目较少。但是，宾语从句也有自己的特殊情况，如介词的宾语，形容词的宾语，宾语从句提前和并列的宾语从句等现象。如： We assumed that there would be more than 100 guests. He told the police in detail what he saw and heard. Nobody is sure what humans will look like in a million years. That will depend on whether they can get the chance. Whether I will have the time I am not sure at the moment. The conductor complained that we were not gifted in singing and that he would never come again. 【表语从句】表语从句的最重要脸谱就是它们应该出现在系动词的后面。如： The only question left is how often the workers are paid. His idea for the coming weekend is that we go skating. 【同位语从句】从脸谱上看，同位语从句最为麻烦。因为它们也是出现在一个名词的后面，起着解释说明的作用。

名词性从句的解题技巧(二)

名词性从句的解题技巧（二）安徽省蚌埠二中----朱正军 B）名词性从句缺表语：从句缺表语比上述情况复杂一些，根据句意分析，如果需要使用连接代词的话，判断选择的方法与上述方法相同，而表达“谁的？”这一所属关系时则用whose (如：I don’t know whose this book is.)。如： 15. I read about it in some book or other. Does it matter ____ it was? 【北京卷2006】 A. were B. what C. how D. which 16. ----Can you do me a favor? ----It depends on ____ it is. 【北京卷2006】 A. which B. whichever C. what D. whatever 17. I want to be liked and loved for _____ I am inside. 【北京卷2010】 A. who B. where C. what D. how 18. Engines are to machines ____ hearts are to animals. 【山东卷2006】 A. as B. that C. what D. which 【这是一个较为特殊的句式结构，从句是第一个are的表语。句意为“发动机对于机器而言就如同动物的心脏。”】答案：15. D 16. C 17. C 18. C。选择方法上文已经讲过，在此不再赘述。如果不能使用连接代词，则根据语义选择适当的连接副词，如Please tell me who/what/where/how he is一句中的几个连接词都是正确的，具体用哪一个要看上下文。 C）名词性从句缺定语：名词性从句缺定语如果指“谁的？”则用whose，如：I don’t know whose book this is. 如果指“什么的？”则用what或whatever，如：I don’t care what person you’d like to make friends with.或You can make friends with whatever person you like. 再如： 19. It is uncertain_____ side effect the medicine will bring about although about two thousand patients have taken it. 【浙江卷2010】 A. that B. what C. how D. whether 该题表达的是“什么样的”，所以答案为B。如果指“哪一个？”则用which或whichever。如： 20. ____ team wins on Saturday will go through to the national championships. 【山东卷2006】 A. No matter what B. No matter which C. whatever D. whichever 【谈及星期六的比赛，当然就有了范围的限制，所以要用which或whichever，意为“哪个队”，分析一下句型结构不难看出连接词既是team的定语，whichever team又是will go through的主语，即“一身兼两职”。同时，No matter wh+只能引导让步状语从句。】答案：20. D。which与whichever之间语法上的区别和who与whoever whom与whomever相同，whichever可解释为any person who/any thing which。二）如果名词性从句中不缺少上述成分，则根据句意有无疑问将连接词的选择分成两种情况：A）从句语义是确定无疑的： a) 从句表达的是“一种事实”则用that。 1. It never occurred to me ____ you could succeed in persuading him to change. 【陕西卷2010】 A. which B. what C. that D. if

赖氏经典英语语法—名词性从句

名词性从句名词性从句包括宾语从句、主语从句、表语从句、同位语从句。名词性从句一共有三种：1）that从句；2）whether从句；3）疑问词所引导的从句。分项说明如下： 1）that从句任何一个主语起首的陈述句前面冠以that，即成that从句。 He enjoys dancing. That he enjoys dancing. 2）whether从句由可用yes/no回答的问句，即一般疑问句变化而成。 a) 问句有be动词时：Is he happy? Whether he is happy. b) 问句有一般助动词（can, will, may, should, ought to, must, have）时： Can he do it? Whether he can do it c) 问句有do, does, did等助动词时：主语与助动词还原，再将do, does, did去掉，后面的动词依人称和时态变化。 Did he come? Whether he came 3）疑问词所引导的从句由疑问词（when, what, how, where, why）等引导的问句，即特殊疑问词，变化而成。 a) 问句有be动词时：What is he doing? What he is doing. b) 问句有一般助动词（can, will, may, should, ought to, must, have）时：主语与助动词还原，前面保留疑问词。Where can he find it? Where he can find it. c) 问句有do, does, did等助动词时：主语与助动词还原，前面保留疑问词，再将do, does, did去掉，动词依人称和时态变化。 What did he write? What he wrote. 注： Who, what, which为疑问代词，若在问句中作主语，变成名词性从句时，结构不变。 Who came here? Who came here. 名词性从句的功能： 1）作主语 Where he lives is still in doubt. 2）作及物动词的宾语 I know that he will go abroad in the near future. 3）作介词的宾语 a)此时仅能用whether从句或疑问词引导的名词性从句作宾语。That从句不可作介词的宾语。 I am worried about whether he can do it. prep. o. I am curious about how he’ll cope with the problem.

英语复合句的用法及解题技巧

英语复合句的用法及解题技巧在高考英语试题中，复合句占有较大的比例，复习时应该注意：１．倡发散思维，忌单向思维，考各种从属句，常常是不同类型的连接词语正误连缀而至，如果不抓住这一点，不从多方面思考选择，就容易以偏概全，误入歧途。２．弄清主从复合句中的每一个从属连接词的意思、用法、主句与从句在时态上的呼应、语气、是否需要倒装、固定搭配及逻辑常识等。３．熟记句型及特殊表达形式。４．注意各分句之间的特点及区别。５．注意有些连接词的省略情况及省略后某些语序发生的变化。总之在做习题时，不能生搬硬套，一成不变，要全方位的思考，摸清出题者的意图，灵活机动，随着不同的语言环境而变化。一、状语从句：状语从句又可分为时间、地点、目的、原因、结果、行为方式、条件、让步及比较等几种形式。１．I'll go with you as soon as I ____my work. A.will finish B.shall finish C.finish D.finished 选Ｃ．在时间、条件状语从句中，主句可能是祈使句、一般将来时或带情态动词，从句用一般现在时。如果主句是过去将来时，从句可以用一般过去时。能够引导时间状语从句、条件状语从句的从属连接词，常见的有：when,until （ti y,directly,unless,as long as,suppose等。如：（１）Unless he comes,we won't be able to go. （２）Suppose it goes on raining,what shall we do? （３）Lu Xun often said,"As long as I am alive,I shall go on studying." ２．No sooner_____the news than they rushed out into the street. A.they heard B.they had heard C.did they hear D.had they heard 选Ｄ．no sooner…than,hardly…when,scarcely… before表示"—…就"，主句一般用过去完成时（h ad+V-ed），从句用一般过去时，如果hardly,no sooner, scarcely放句首，主谓倒装。３．Although he is considered a great writer,____(MET'91) A.his works are not widely read B.but his works are not widelyread C.however his works are not widely read

名词性从句的解题技巧

名词性从句解题方法〈方法〉一一先大类后口诀法第一步：先分析出大的类别一一定从？ /名从？ /状从？即分析所缺部分在主句中的成分从而确定从句大的类别第二步：口诀逐一解决： (I)名词性从句。一一口诀一一先成分后含义 (ID定语从句。一一口诀一一先成分后先行词 (ill)状语从句。——口诀：翻译即可例如：名词性从句的口诀执行方法是：分析引导词在从句中的成分 A 做名词性成分--- what/which/who/as (+W~ever 型) B做非名词性成分 a不做成分：that/辻/whether (whether霸王原则) b 做状语成分：when/where/why/how 两类，剩余的靠含义直接翻译即可解决。AB —旦分出例如I A computer can only do ______ you have instructed it to do. (01 年31 题) A. how B. after C. what D. when 解：第一步：先分析出大的类别 A computer can only do中的do是及物动词，后而缺少do的对象，所以考察名词性从句问题

第二步：口诀一一先成分后含义从句you have instructed it to do中的do是及物动词，后而缺少do的对象，所以前面的空在后面的从句内充当名词性成分，所以可以选择的引导词就可以排除AD（因为这两个引导词在从句中是充当状语的），而选项B是名词性从句中不存在的引导词，所以B也不对，最后就剩下一个正确选项C 如此这样一步一步下来，逐一进行排除和选择，最终总是可以直接定位到正确的答案。而这个过程应该是完全被熟化在脑中的一个过程, 按部就班的操作直至正确答案自然而然的浮出水面。其他类别的题目也应该仿照此类，依次完成。、建立良好的做题习惯，沉稳面对每一个考验。2 优秀是一种习惯。建立良好的做题习惯无疑对我们来讲，是高质高效的完成题目所必不可少的方针与策略。第一步，先看看选项。这样可以让我们知道这个题目木身到底考察什么，只有它考什么知识点我们才去找相应的方法去击破它。例如1. The water cool when I jumped into the pool for morning exercise. （06 年29） felt B. is felt C. felt D. feels 这个题目AB都提及了被动语态，显然这个题目首先得先考虑被动与否的问题。（feel这个感观动词做系动词时无被动语态，所以上来就

高考英语语法复习三：名词性从句

高考英语语法复习三: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, as if。that 无词义,在从句中不担任成分,有时可省略; if (whether, as if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,as if(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as if 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. Who will go is not important. 2、用it作形式主语,主语从句放在句末。 e.g. It doesn't matter so much whether you will come or not. 3、that引导主语从句时,不能省略。 e.g. That he suddenly fell ill last week made us surprised.
