高中英语 名词性从句的分类与识别
名词性从句讲解和区分
名词性从句讲解和区分作为高考的热点,名词性从句几乎在历年的高考试卷中都有涉及。
下面就是小编给大家带来的名词性从句讲解和区分,希望大家喜欢![关系代词和关系副词的误用]例1 (2016·全国卷Ⅰ) My uncle is the owner of a restaurant close to that I live.解析that→where。
本题考查宾语从句,引导词在从句中充当地点状语,所以将that改为where。
例2 (2015·全国卷Ⅱ)As natural architects,the Pueblo Indians figured out exactly thick the adobe walls needed to be to make the cycle work on most days.解析 how。
根据语境和空后的形容词thick可知应用how引导宾语从句,此处表示要弄清楚到底土坯房的墙需要“多”厚。
故答案为how。
点拨若从句缺少主语、宾语、表语或定语,则考虑用关系代词;若从句缺少时间、地点、原因、方式等状语成分,则使用关系副词(when/where/why/how)。
[if和whether的误用]例3 He asked her the question if they can be friends.解析if→whether。
question后为同位语从句,只能用whether 来引导,故而将if改为whether。
例4 It doesn’t matter so much you will come or not.解析考查主语从句。
句意:你来还是不来,这不怎么重要。
代词it作形式主语,真正的主语是whether引导的主语从句。
点拨在表达“是否”这一意思时,我们经常会用到whether和if,但以下几种情况只用whether不用if:1. 在表语从句、主语从句、同位语从句中;2. 在介词后的宾语从句中。
名词性从句(同位语从句)
在否定同位语从句中,如果否定词not没有实际意义,可以直接省 略。
简化后句子的含义和功能
去除连词that后,句子的 含义和功能不变,但句子 更加简洁明了。
省略否定词not后,句子 的含义和功能不变,但句 子更加简洁明了。
合并句子后,句子的含义 和功能不变,但句子更加 流畅自然。

同位语从句与其他从句的辨析
定语从句与同位语从句的区别
定语从句用于修饰名词,限定名词的范围,而同位语从句用于补充说明名词的具体内容。
状语从句与同位语从句的区别
状语从句用于表示时间、地点、条件、目的等,与主句关系紧密,而同位语从句与主句关系相对松散,是对名词 的额外说明。
去除连词that
在同位语从句中,连词that可以被省略。
去除助动词be
如果同位语从句中的主语和主句主语一致,助动词 be可以被省略。
去除not
在否定同位语从句中,not可以被省略。
简化方法
直接删除连词that
在同位语从句中,如果连词that没有实际意义,可以直接删除。
合并句子
如果同位语从句中的主语和主句主语一致,可以将同位语从句的主 语和主句主语合并,形成一个简洁的句子。
四类名词性从句详解
四类名词性从句详解所谓名词性从句,就是指其作用相当于名词的从句,它包括主语从句、表语从句、宾语从句和同位语从句。
一、主语从句1.引导词:主语从句就是在复合句中用作主语的从句,引导主语从句的引导词主要有三类:一是that;二是whether;三是那些可以用作疑问词的词语,如what, who, which, when, where, how, why等。
如:That we shall be late is certain. 我们要晚了,这是确定无疑的。
What he says is not important. 他说的话并不重要。
How this happened is not clear to anyone. 这件事怎样发生的,谁也不清楚。
Which side wins makes no difference to him. 哪边赢他都无所谓。
Whether it will do us harm remains to be seen. 是否对我们有害还要看一看。
2.形式主语:有时为了避免句子显得“头重脚轻”,可用it作形式主语放在句首,而把真正的主语放在句末。
如:It’s a pity that he didn’t come. 很遗憾他没来。
It’s not yet known what she did. 她做什么还不得而知。
It was uncertain whether he could come or not. 他是否会来还不肯定。
这三句句首的it均为形式主语,相应的真主语分别是that he didn’t come / what she did / whether he could come or not。
二、表语从句表语从句就是在复合句中用作表语的从句。
一般说来,可用于引导主语从句的引导词也可用于引导表语从句,如that, what, who, which, when, where, how, why, whether等。
高中英语名词性从句用法
高中英语名词性从句用法从句是相对于主句而言的,即它是从属于某一个主句,而不能单独作一个句子。
在英语中,主要有三大从句,即名词性从句(包括主语从句,宾语从句,表语从句,同位语从句)、形容词性从句(即定语从句)、副词性从句(即状语从句,包括时间、条件、结果、目的、原因、让步、地点、方式等)。
在句子中起名词作用的句子叫名词从句(Noun Clauses)。
名词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。
引导名词性从句的连接词可分为三类:(1)从属连接:that,whether,if(不充当从句的任何成分)(2)连接代词:what,whatever,who,whoever,whom,whose,which.(3)连接副词:when,where,how,why名词性从句知识点汇总1、名词性从句的分类名词性从句,包括四种从句,即主语从句、宾语从句、表语从句、同位语从句。
因为主语、宾语、表语、同位语这四种成分均可以由名词构成,所以这四种从句在主句中都充当了名词的作用,故将这四种从句统称为名词性从句。
如:1.That she will help me made us happy.(主语从句)2.I can understand what he said.(宾语从句)3.This is where I was born.(表语从句)4.The fact that a heavy earthquake happened made me crazy.(同位語从句)2、名词性从句的连接词分类1.that(无含义,不充当成分)2.whether,if(有“是否”的含义,但不充当成分)3.连接代词:what,whatever,who,whoever,whom,whomever,whose,which,whichever.(在从句中做主语、宾语、表语和定语)连接副词:when,whenever,where,wherever,how,however,why (在从句中做状语)4. as if,as though,because(不充当成分,在名词性从句中只引导表语从句)3、连接词that 在名词性从句中可以省略的三种情况1.it 做形式主语,that引导主语从句时It is said (that) he has been studying abroad.据说他一直在国外学习。

高考英语名词性从句讲解I. 名词性从句概念名词性从句指的是由一个从句来充当名词的作用,如主语,表语,宾语,同位语等。
II. 名词性从句的分类1. 主语从句(1)概念:在整个句子中作主语。
(2)引导词:主语从句引导词分为三类,具体内容如下所示:①连词:that whetherthat:不同于其它的连词,它不充当句子的成分,只是单纯的连接词,通常不可以省略。
分句置于句首时,that绝对不可以省略。
eg. That price will go up is certain.That he finished writing the composition in such a short time surprised us all.whetherif 不能用在主语从句中,而是用whethereg.

从句类型及判别方法
从句类型及判别方法从句是指在一个句子中充当成分的句子,它通常由连词引导,用来修饰名词、形容词、副词或是充当主语、宾语等成分。
从句在英语语法中占据着重要的地位,因此对于从句的类型及判别方法的掌握是非常必要的。
本文将从从句的类型和判别方法两个方面进行详细介绍。
一、从句的类型。
1. 名词性从句。
名词性从句是指在句子中充当名词成分的从句,分为主语从句、宾语从句、表语从句和同位语从句。
主语从句通常由连接词“that, whether, if, what, who, which, whoever, whatever”等引导,用来充当主句的主语;宾语从句通常由连接词“that, whether, if, what, who, which, whoever, whatever”等引导,用来充当主句的宾语;表语从句通常由连接词“that, whether, if, what, who, which, whoever, whatever”等引导,用来充当主句的表语;同位语从句通常由连接词“that, whether, who, which, what”等引导,用来对名词进行解释说明。
2. 定语从句。
定语从句是指在句子中充当定语的从句,用来修饰名词或代词。
定语从句通常由连接词“that, which, who, whom, whose”等引导,用来对名词进行修饰。
3. 状语从句。
状语从句是指在句子中充当状语的从句,用来修饰动词、形容词、副词或整个句子。
状语从句根据其所表示的时间、原因、条件、结果、目的等不同情况,分别由不同的连接词引导,如时间状语从句由“when, while, before, after, since, until”等引导;原因状语从句由“because, since, as”等引导;条件状语从句由“if, unless,provided that”等引导;结果状语从句由“so that, such…that”等引导;目的状语从句由“so that, in order that”等引导。
识别四类名词性从句的方法
从句在复合句中作主语时被称为主语从句;作宾语时被称为宾语从句;作表语时被称为表语从句;作同位语时被称为同位语从句。
如何识别这四类名词性从句呢?一、如何识别主语从句利用基本概念进行辨别:主语从句就是在复合句中作主语的从句。
识别要领:主语从句一般位于谓语动词的前面,但是应注意倒装时候的用法。
备注:为了避免主语从句放于句首造成头重脚轻的现象,常会使用it 作形式主语放于句首,而把主语从句放于句尾。
常见的主要有以下5种结构:1.It+be+adj.(obvious/nature/clear/true/good/surpris⁃ing/probable/wonderful/fortunate 等)+that+主语从句。
2.It +be +过去分词(reported/said/thought/an⁃nounced/believed/expected/confirmed 等)+that +主语从句。
3.It+be+名词(a pity/an honor/good news/no wonder/a fact 等)+that+主语从句。
4.It+不及物动词(词组)(happen/look/seem/appear/turn out 等)+that+主语从句。
5.It+及物动词(shock/worry 等)+that+主语从句。
引导词:连词有whether,that,if ;连接代词有who,what,which,whatever,whoever,whom,whose ;连接副词有where,when,why,how 等。
考例1:Exactly when Jenny will go to college is stillunclear,but I know she ’s preparing things for college now.(画线部分为主语从句)简析:画线部分在系动词is 之前,故可判断画线部分是主语从句。

高中英语名词性从句详细讲解
名词性从句带有从句的复合句就是用连接词把主句和从句连接在一起。
高中英语中共有三大从句:形容词性从句(即定语从句);二、名词性从句;三、状语从句。
形容词性从句即定语从句,相当于一个形容词,作先行词的定语,用来修饰前面的名词或代词的。
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,名词性从句分为主语从句、表语从句、宾语从句和同位从句。
主语从句、表语从句、宾语从句只有在主句句子的成分残缺时才可以考虑使用这三大从句。
同位语则是对前面某一名词的展开,即对前一名词的具体说明,做进一步解释,两者是同等,并不是定语从句的修饰与被修饰关系。
名词性从句考得最多的是宾语从句,其次是主语从句,再次是表语从句,而同位语从句则很少考查。
名词性从句的连接词:1.从属连接词:that(无任何词义),whether/if(均表示“是否”表明从句内容的不确定性),as if /as though (均表示“好像”“似乎”)。
以上词在从句中均不充当任何成分,只起连接作用。
根据句意,如果连接代词、连接副词、whether/if 和as if/as though都用不上时,才用that作连接词(因为that本身无任何含义)。
2.连接代词:what,who, whom, whose,which,whatever, whoever,whichever,whomever。
有词义,在从句中担任成分,如主语、表语、宾语、或定语。
从句一定要用陈述语序。
\3.连接副词:when,where,why,how, how many,how much,how often。
有词义,在从句中担任成分,作状语。
【注意】连接代词与连接副词既保留自己的疑问含义,又起连接作用,在从句中充当成分。
4.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 the news that our team had won.(一)主语从句…第一部分:常规主语从句,即从句在复合句中充当一个主语。
高二英语语法名词性从句要点解析
高二英语语法名词性从句要点解析【考纲解读】名词性从句是历年高考的重点和难点也是热点。
名词性从句相当于名词,可用作主句的主语、表语、宾语和同位语。
因此,名词性从句分为主语从句、表语从句、宾语从句和同位从句。
引导名词性从句的连接词有: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;连接副词:when, where, why, how,有词义,在从句中担任成分,作状语;连接词:that, whether, if, as if,if (whether), as if虽有词义,但在从句中不担任成分;that 无词义,在从句中不担任成分,有时可省略。
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。
【知识点梳理】高二英语语法名词性从句要点:(一)名词性从句的结构:名词性从句起名词作用在句中做主语,表语,宾语和同位语构成:主语从句;表语从句;宾语从句和同位语从句。
引导名词性从句的连词有三类:that;whether; wh-疑问词。
例句:1.The result of this French influence was that the English language ended up with many French words such as table, animal and age.2. They realize that it is of great value to record and teach them to the younger generation.3. I want to tell the reader that these hills and fields are most beautiful, with many small and clear rivers, and rich fields bearing fruit and grain.4. Some people feel that Wales is an ancient fairy land.5. What interested him was that the whole world had been mapped 70 years before Columbus.6. What is certain that the book has made many people think about the achievements of Zheng He and other Chinese captains and their role in discovering the world.7. That most of these are now threatened and may disappear is a serious matter to the people in Britain.8. This gave him the idea that the Chinese perhaps first discovered America.(二)同位语从句在名词idea; fact; news; thought; suggestion/advice; problem; proof等词后面带上that+陈述句这部分从句解释了前面的那些名词所指的内容,与那些名词起着同等作用的句子成分,叫同位语从句。
名词性从句详解

(完整版)高中英语名词性从句讲解
适用文档名词性从句解说在复合句中起名作用的从句叫做名性从句。
它包含主从句、从句、表从句和同位从句。
名性从句是中学段的一个重要法目,在年的高考取几乎都波及到,而且每年的命各有化。
解析届高考名性从句考的焦点主要有以下六个方面1.考名性从句的序2.考引 that与 what 的区3.考 it 在名性从句中作形式主或形式的用法4.考 whether 与 if 的区5.考名性从句中的疑+ever 引的名性从句与no matter+ 疑引的状从句的区6.考名性从句的虚气法重点解析一、名性从句主从句、表从句、从句、同位从句,在整个句子中所起的作用,相当于一个名。
所以,四种从句通称名性从句。
引名性从句的接可分三:接: that, whether, if(不充任从句的任何成分)接代: what, whatever, who, whoever, whom, whose, which.接副: when, where, how, why1.主从句作句子主的从句叫主从句。
主从句往常由附属that ,whether ,if和接代what ,who,which ,whatever , whoever 以及接副 how, when, where, why 等引。
that 在句中无,只起接作用;接代和接副在句中既保存自己的疑含、又起接作用,在从句中充任从句的成分。
比如:What he wants to tell us is not clear.他要跟我什么,不清楚。
It is known to us how he became a writer.我都知道他是如何成一名作家的。
Where the English evening will be held has not yet been announced.英晚会将在哪里行,没有宣告。
有防止句子重脚,常用形式主it取代主从句作形式主放于句首,而把主从句置于句末。
主从句后的一般用数形式。
