高考英语复习 名词性从句讲解
名词性从句一、名词性从句与简单句的区别在英文中,名词或名词短语主要充当四种句子成分:主语、宾语、表语和同位语。
如果把句子当作名词来用,分别充当另一句话的主语、宾语、表语或同位语,于是便构成了四种从句:主语从句、宾语从句、表语从句和同位语从句。
因为这四种从句在本质上相当于名词的作用,所以将其统称为名词性从句。
请看下表:在英语中,相当于名词作用的句子有三类,陈述句、一般疑问句以及特殊疑问句。
因此,名词从句就是用三种句子来分别充当另外一个句子的四种句子成分,者就构成了名词从句的本质特征。
但是,这三种句子不是直接放在另一个句子中作成分,而是要作各种变化调整。
接下来将具体讨论。
二、陈述句作句子成分1. 要在陈述句句首加上t hat用”that+陈述句”这一结构分别充当另一个句子的四种成分。
2.为什么要加that?对于陈述句,为什么要在其句首加that 后才能用它作成分呢?而为什么在宾语从句中that 又可以省去呢?因为在英文中,句子的核心意思主要是靠谓语部分来表达,一个句子只表达一个核心意思,也就是只能有一个谓语部分。
而添加that,相当于一个“指路牌”,能够帮助我们指明段句的方向,而不至于造成歧义。
而对于宾语从句,主句的谓语已经出现,后面所接的成分自然是谓语,所以在不会影响句子的意思下,是可以把that 省去的。
三、一般疑问句作句子成分1.用w hether 或if 引导先将疑问句的倒装语序变成陈述句语序(即主语放在谓语的前面),并在句首加上whether 或if(if 只用在宾语从句中)来引导,以保留原句的疑问意义。
即“whether+陈述句”2. if 还是 whether?1)if 一般只用于引导宾语从句,而 whether 可引导宾语从句在 内的其他名词从句。
IF he comes or not makes no difference. 成 Whether he comes or not makes no difference.2)if 不和 or not 直接连用,即一般不说 if or not, 但可以说 if...or not 。

名词性从句详解及练习
各类从句详解英语从句可以分为名词性从句、定语从句和状语从句三大类:下面我们逐一进行说明:一、名词性从句(主语从句、表语从句、宾语从句、同位语从句)主语从句、表语从句、宾语从句和同位语从句在复合句中的充当的成分和其名称相同,分别作主句的主语、表语、宾语和同位语。
上述这四种从句均被称为名词性从句。
所有的名词性从句均不能用逗号分开,并且它们都用相同的关联词,关联词如下:①主从连词:that (无意义), whether (是否), if (是否)(在句子中不充当任何成分)②连接代词:who (谁), whom (谁), whose (谁的), what (什么), which (哪一个)③连接副词:when (什么时候), where (什么地方), how (怎样), why (为什么)主从连词只起连接作用,连接代词和连接副词除了起连接作用外,还充当从句某一个成分。
另外,可以用whatever, whichever, whoever, who(m)ever等连接代词引导名词性从句,来加强语气。
下面分别对各种名词性从句进行介绍(一)主语从句(subject clause)在主句中用作主语的主谓结构称之为主语从句。
例如:That he will come to the discussion is certain.他来参加讨论是确定的。
That the moon moves round the earth is well known to all of us.月球绕地球转动,这是我们大家都熟知的。
When the meeting is to be held has not yet been decide.会议什么时候召开还没有决定。
主语从句放在句首,句子常常显得比较笨重,因此通常可以把it放在句首,作形式主语,而将主语从句放在后面。
例如上面的句子可以分别改写为:It is certain that he will come to the discussion.It is well known to all of us that the moon moves round the earth.It has not yet been decide when the meeting is to be held.下面再举一些例句:What they are after is profit.他们追求的是利润。

高二英语语法名师讲解:名词性从句
高二英语语法名师讲解: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,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。

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。
