名词性从句

语法专题二:名词性从句1. 名词性从句的基本概念:1) 主语从句:在句中充当主语;亦可用it作形式主语,主语从句置于句末。

2) 宾语从句:在句中充当及物动词或介词的宾语;亦可用it作形式宾语,宾语从句置于句末。

3) 表语从句:在句中充当系动词的表语。

4) 同位语从句:常置于fact, idea, news, promise, doubt, suggestion, possibility, belief等表示有内容的名词后,起解释、说明作用。

2. 注意:1) 名词性从句要用陈述句语序。

2) 名词性从句中缺少主语、表语、宾语时:常用what 导,亦可用which表示选择,用who/whom/whoever指人。

缺少状语:用where(表地点), when(表时间), how(表方式), why(表原因)。

3) 如不缺成份:主语从句、同位语从句用that引导,不能省略;表从、单个动词宾从可省略引导词that;介词宾从、第二个宾从,引导词that一般不省略;it作形式主语或宾语时,引导实际主从或宾从,一般that不省略;当主从、宾从本身为复合句时,引导词that不省略。

如:He told us sadly that what he had done secretly was discovered by his parents.4) 含宾从的复合句中,主句和从句的时态保持一致,但如果从句中表示是客观现象,虽然主句是过去时态,从句仍用一般现在时。

5) 主语从句做主语,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做主语时,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。

6) 当主句是I/We think(或suppose, expect, believe, imagine, guess)时,其后的宾语从句如果是否定的,常常把否定词not从从句中移到主句中。

7) 只能用whether,不能用if表示“是否”的情况如下:(1) 在表语从句和同位语从句中;(2) 在主语从句中,如果用it做形式主语,whether和if都能引导主语从句,否则,只能用whether(3) 在介词之后;(4) 后面直接跟动词不定式;(5) 与or not连用;(6) 引导让步状语从句,只能用whether。

语序:陈述语序
在句中充当主语的从句称为主语 从句。英语中主语从句的句型可分 为两大类: 直接将主语从句放在主语位置上; 用it作形式主语,将真正的主语从 句后移,放在其他成分后。
让我们先说说第一类吧!
一、连接词(只起连接作用,在从句中不充当句子成分)
that:无词义。 e.g.: 他赢得比赛一事在我国引起巨大轰动。 That he won the game made a tremendous stir in our country. whether:“是否”。可单独使用,也可与or或or not连用。 e.g.: 我们明天是否能去春游取决于天气。 Whether we can go for a spring outing depends on the weather. 他们是否会来还未告诉我们。 Whether they will come has not been told to us.
四、主语从句与主谓一致
一个从句作主语时,谓语动词通常用单数形式, 特别是用it作形式主语的句型。 e.g.: Whether this kind of chemicals is better has not been tried.
当what引导主从,应遵循意义一致原则,谓语动 词选用相应形式。表语是复数时,谓语动词用复数 形式。 e.g.: What we do willingly is easy. What they were searching for were the missing gems.
Introduction

名词性从句

名词性从句1.名词性从句的定义名词性从句是起名词作用的从句,这些从句可以作为一个整体来看,其作用就相当于一个名词,在复合句中作主语,宾语,表语和同位语。

名词性从句包括主语从句,表语从句,宾语从句,同位语从句四种。

2.名词性从句的连接词名词性从句通常由一个连接词和主句相连。

连接词很重要,它既是联系主句的纽带,又是从句的标志,通过连接词,我们可以辨认不同从句的性质。

一.从属连接词(在从句中不充当任何成分,只起到连接从句的功能)A.that 只是引导名词性从句,本身并没有实际意义,在从句中不充当任何句子成分。

That he will come to the meeting is certain.(主语从句)The fact remains that we are behind the other group.(同位语从句)B.if和whether具有“是否”的意义,但是whether比较正式,在口语中人们经常if, if 和whether在名词性从句中尽管不充当任何的成分,但不可以省略。

C.whether不能替代if的情况1.if只能引导宾语从句(做介词宾语的情况除外),而whether 可以引导所有的名词性从句。

She asked if/ whether that was enough.Whether the football match will be played depends on the whether.The question is whether we can arrive there on bus.2.whether引导宾语从句做介词的宾语,if没有这种用法It depends on whether it will be fine.3.whether后紧跟不定式He was wondering whether to go home.4.or not 可直接跟在whether后面,但不可以直接跟在if后面。

名词性从句的三种类型及例句解析

名词性从句的三种类型及例句解析

名词性从句的三种类型及例句解析名词性从句是指在一个句子中充当名词的从句。

它可以作主语、宾语、表语和同位语等,并能够起到连接子句与主句的作用。

在英语语法中,有三种主要类型的名词性从句:宾语从句、主语从句和表语从句。

本文将详细解析这三种类型,并举例说明其用法。

一、宾语从句宾语从句作为一个整体出现在主句中的动词后面,充当主句的宾语。

它常常引导由that、whether/if、wh-疑问词引导的从句。

下面是一些例句:1. 主句:He asked me a question.宾语从句:He asked me whether I had finished my homework.解析:宾语从句"whether I had finished my homework"作为动词"ask"的宾语,表达了一个疑问。

2. 主句:She doesn't know the answer.宾语从句:She doesn't know what the answer is.解析:宾语从句"what the answer is"作为动词"know"的宾语,表示对答案的不知道。

3. 主句:They wonder if he will come to the party.宾语从句:They wonder if/whether he will come to the party.解析:宾语从句"if/whether he will come to the party"作为动词"wonder"的宾语,表达了对他是否会来参加派对的疑问。

二、主语从句主语从句作为一个整体出现在句子的最前面,充当主句的主语。

它通常由that引导,也可以由wh-疑问词引导。

以下是一些例句:1. 主句:It is important to learn a foreign language.主语从句:That she is a hardworking student is important.解析:主语从句"That she is a hardworking student"作为句子的主语,强调了她是一个勤奋的学生的重要性。

名词性从句复习

从出题者的角度,就是要考察名词性从句中的语序以及引导词之间的区别。有时候,会结合插入语或名词与同位语隔开,或使句子结构复杂化等使得难度增加。其实,总的难度和变化都不大。但是从考生的角度来说,如果考生对句子结构掌握不过硬,对某些词或词组的用法不了解,就会容易造成和定语从句、状语从句的混淆,造成根本环节的误判而用其他从句的规则去解题。造成丢分。

⒊连接副词:引导从句并作从句的状语 when—表示时间 where—表示地点 why—表示原因 how—表示方式 ①When we’ll have a meeting is not decided. ②I don’t know where I can buy such a book . ③ Why he did it will remain a puzzle forever. ④The question is how we should carry out the plan.
正:It was doubtful if /whether Mary really heard him.
误:If Mary really heard him is really doubtful.
正:Whether Mary really heard him is really doubtful.

名词性从句

名词性从句

名词性从句在复合句中起名词作用的从句叫做名词性从句。

它包括主语从句、宾语从句、表语从句和同位语从句。

名词性从句是中学阶段的一个重要语法项目,在历年的高考中几乎都涉及到,并且每年的命题各有变化。

一、名词性从句主语从句、表语从句、宾语从句、同位语从句,在整个句子中所起的作用,相当于一个名词。

因此,这四种从句通称为名词性从句。

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, why1.主语从句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:What he wants to tell us is not clear. 他要跟我们说什么,还不清楚。

It is known to us how he became a writer. 我们都知道他是如何成为一名作家的。

Where the English evening will be held has not yet been announced. 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:It is necessary (important, natural, strange, etc.) that …It is a pity (a shame, no wonder, etc.) that…It is suggested (requested, proposed, desired, etc.) that主语从句的例句:That he was won the prize is true.It is true that he has won the prize.What he said at the meeting is right,Whether he will come or not is unknown.Whoever comes will be welcome. Why he did it is not quite clear.2. 宾语从句名词句用作宾语的从句叫宾语从句。

名词性从句
The reason why he was late was that he missed the early bus. 他迟到的原因是他没赶上早班车.(此句中的that不可用because代替)
D.引导同位语从句时,切不可错用which。例如:
Word has come that some American guests will come to visit our school next week. 有消息说下周将有一些美国客人来我校参观。
____ you have seen both fighters, ____ will win?
A. Since; do you think who B. As; who you think
C. When; whoever D. Since; who do you think
解析:根据上面的讲解,不难知道答案是D。其中do you think是插入成分,其余部分是宾语从句,作think的宾语;由于引导词在从句中作主语,所以要用主格who(不用whom)。
-I drove to Zhuhai for the air show last week.
-Is that ____ you had a few days off?
A. why B. when C. that D. where
解析:答案是A,why引导的从句作表语,同时why在从句中作原因状语。这里之所以选why,而不是when或 where等,唯一的依据便是句子的逻辑含义,及语境。
whatever,whoever,whichever引导名词性从句
一、基本用法概说英语中的-ever 词主要包括 whatever, whoever, whichever, whenever, wherever, however 等,其中可引导名词性从句的主要有 whatever, whoever, whichever等,其中可引导Roman'; mso-ascii-font-family: 'Times New Roman'">。这里所说的名词性从句主要指主语从句和宾语从句,它们通常不用于引导同位语从句,同时也很少用于引导表语从句。如:Whatever he said was right. 无论他说什么都是对的。(引导主语从句)I don’t believe whatever he said. 无论他说什么我都不信。(引导宾语从句)在某些特定的语境中,也可用于引导表语从句。如:

因此,在使用名词性从句时,我们需要根据语境和句子的需要选择适当的引导词。

名词性从句一.概述:在句子中起名词作用的各种从句统称为名词性从句。

根据它们在句中的语法作用,这类从句又可分为主语从句、表语从句、宾语从句和同位语从句。

二.名词性从句连接词四.if, whether的区别1.引导主语从句时,如果主语从句放在句首,只能用whether不能用if引导,但是如果用it 做形式主语,而把主语从句放在句末时,也可以用if引导.2.引导宾语从句时常放在动词know, ask, care, wonder之后,if和whether均可。

少数动词,如: leave, put, discuss, doubt后的宾语从句常用whether. 。

3.在介词后面的宾语从句中,在表语从句、同位语从句中,表“是否”,只能用whether;4.whether和if都可以和or not连用,但是whether 之后可以直接跟or not,而if不可以。

I do n’t know whether or not I will stay.(只能用whether)5.在不定式前只能用whether.如:I can’t decide whether to stay. 我不能决定是否留下。

五.与“命令、要求、建议”等相关的名词性从句中通常用虚拟语气,虚拟语气的构成是“should+动词原形”或省去should,直接用动词原形。

六.名词性从句以考查引导词为主,同时考查时态,语序,与其它从句的区别以及混同虚拟语气的考查。

一.主语从句1.主语从句定义:在复合句中充当主语的句子叫做主语从句。

名词性从句讲义一.定义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。

二.分类根据名词性从句在复合句中所做的成份,可将其分为四种:主语从句、表语从句、宾语从句、同位从句。

主语从句:在复合句中作句子主语的从句叫做主语从句 例如:宾语从句: 例如:I think Your success will largely depend on what you do. (介词后的宾语从句) I am glad that you can come . (形容词后的宾语从句) 表语从句:在复合句中做表语的从句叫做表语从句 例如:The fact is that he has lied to you.例如:Will you keep your promise that you will resign? 三.引导词及其作用:1.连词: that (无实意), if (是否), whether(…or not)(是否), as if (好像);that 无词义,在从句中不担任成分,有时可省略;whether, if, as if 虽有词义,但在从句中不担任成分,不能省略。

名词性从句
一.什么是从句?
引导词+句子——也就是引导词+主语+谓语。

二.什么是名词性从句?
1.名词充当的成分
The movie looks terrific. ——主语
I appreciate the mather. ——宾语
She is a ghost. ——表语
I enjoy the part, the end. ——同位语(同样位置)
例:Liu, a physically attractive individual, keeps my teacher. 只要在作文中见到名词,都可以在后面再加一个名词,作为他的同位语,前后要用逗号隔开。

例:Pollution, a universal issue throughout the world, becomes
increasingly grave under modern conditions.
Confidence, a Chinese conventional virtue,keeps exceedingly(strikingly\more than) indispensable under modern conditions.
作文技巧:
万能同位语——全球共同话题(坏的话题),中华民族传统美德(好的话题)2.什么是名词性从句。

What I saw looks terrific. ——主语从句
I appreciate what she did. ——宾语从句
She is who we should admire. ——表语从句
I enjoy the part that she knew the truth. ——同位语从句
名词在句子中能够充当的成分,从句在句子中也能充当。

包括四类:主、宾、表、同。

三.名词性从句的引导词
三类:(1)that:从句是陈述句(不需要回答的句子)。

在句子中,没有任何意思,也不充当任何成分。

(2)whether:从句是一般疑问句(yes、no回答的问句)。

在句子中,翻译为“是否”。

(3)特殊疑问词:从句是特殊疑问句(特殊疑问词开始的问句)。

在句子中,翻译为自己的意思。

注意从句格式:引导词+主语+谓语。

即:都为陈述句的格式。

That women(可数名词不能单独使用,要么使用单数,要么使用复数) are always right proves the(分不清单词的可不可数加上the) common knowledge. ——主语从句
I am wondering whether I should lose weight. ——宾语从句The point proves when wealth will be available for you. ——表语从句
Why they left the hometown for Tibet remains a mystery. ——主语从句
My perspective keeps that confidence can make girls more elegant. ——表语从句
四.考点分析
1.写作
(1)主语从句
主语从句的满分表达:把主语从句放到句末,加it做形式主句。

可以写在作文中的任何一个陈述句的前面,用来拉长句子。

It proves common knowledge that … 显而易见、众所周知
It looks beyond dispute that … 显而易见、众所周知
It has been widely accepted that … 显而易见、众所周知
It keeps my perspective that … 在我看来、我认为
It has been widely accepted that the issue of keeping pets has been brought into the limelight.
(2)同位语从句
He managing to find a girlfriend, the matter makes us delighted.
The matter makes us delighted that he manages to find a
girlfriend. (放到句末的同位语从句)
The matter that he manages to find a girlfriend makes us
delighted. (基础的同位语从句)
The news was spread the whole village that her husband was gone.
Nothing could not cover the truth that he is getting old.
manages to do 成功做某事… affair 指风花雪月的事情
2.长难句分析:能够识别各个名词性从句,并且能够通顺的翻译出来
(1)识别主语从句:引导词在句首,并且从句后没有被逗号隔开,就一定是主语从句。

When I will love you is obvious. ——主语从句
When I love you, I will marry you. ——状语从句
Whether the government should increase the financing of pure
science at the expense of technology or vice versa often depends on the issue of which is seen as the driving force.
At the expense of 以…为代价。
