2023届高考英语语法名词性从句精讲之四大从句用法大全讲义

2023年高中英语语法名词性从句精讲之:四大从句用法大全主语从句主语从句的概念:如果一个句子在复合句中充当一个主语,那么这个句子就是主语从句。
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。
主语从句用法:1、主语从句的引导词:主语从句通常由连词that和whether、连接代词或连接副词以及关系代词型what引导:如:That he is still alive is a wonder. 他还活着,真是奇迹。
When we arrive doesn't matter. 什么时候到没有关系。
What we need is money. 我们需要的是钱。
What I want to know is this. 我想知道的就是这一点。
Whether they would support us was a problem. 他们是否会支持我们还是一个问题。
2、主语从句与形式主语it:有时为了考虑句子平衡,通常在主语从句处使用形式主语it,而将真正的主语从句移至句末。
这分三种情况:(1)对于以连词that引导的主语从句,通常用形式主语代主语从句:如:It's a pity that he didn't come. 很遗憾他没来。
(2)对于以连接代词(副词)引导的主语从句,可以使用形式主语代主语从句,也可直接在句首使用主语从句:如:Whether they would support us was a problem. 他们是否会支持我们还是一个问题。
It was a problem whether they would support us. 他们是否会支持我们还是一个问题。
(3)对关系代词型what引导的主语从句,通常不用形式主语,总是主语从句放在句首:如:What we need is money. 我们需要的是钱。

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 。

高中英语名词性从句精讲

高中英语名词性从句精讲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。
