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 。

高考英语名词性从句详解易错点引导词what 与that 的区别;引导词whether 和if 的区别;名词性从句的语序;who / whoever,what / whatever 等的区别;where,when,why 等连接副词引导的名词性从句;“介词+ who(m)”引导的宾语从句与“介词+who(m)”引导的宾语从句的区别;名词性从句中有插入成分时;引导词that 的省略;同位语从句引导词where,when 的用法特点一、引导词what 与that 的区别引导主、宾、表语从句时,what 要充当主语、宾语或表语等句子成分,that 不作任何成分,而只在语法上起连接作用。

例如_________ we can’t get seems better than _________ we have.A. What;whatB. What;thatC. That;thatD. That;what解析:本句包含一个主语从句和一个宾语从句,且两个从句都缺乏宾语,可见两个引导词都必须充当从句的宾语,所以答案为A 项。

在下面的例句中,that 不充当任何成分,只起语法连接作用(因为句子本身不缺成分):That the former Iraq president Saddam was captured has been proved.二、引导词whether 和if 的区别通常,引导主语从句、表语从句和同位语从句时,连词要用whether,而不用if ;习惯上也只能说whether or not,而不说if or not .例如:_________ the meeting will be held in Beijing is not known yet.A. WheneverB. IfC. WhetherD. That解析:题中的从句位于句首,不难知道这是一个主语从句,根据句意,答案为 C 项。

但如果宾语或主语从句为否定句时,只能用that,不能用whether 引导。

高考英语名词性从句讲解

高考英语名词性从句讲解

高考英语名词性从句讲解【考情分析】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。

今后对名词性从句的考查仍将集中在关联词的选用上,特别是对what引导的名词性从句的考查。

名词性从句与其他从句的混合考查将在今后高考中占据一席之地。

【知识点归纳】名词性从句的用法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、介词宾语等,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。

一、引导名词性从句的连接词引导名词性从句的连接词可分为三类:连词:that(无任何词意);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”)。

以上在从句中均不充当任何成分连接代词:what, whatever, who, whoever, whom, whose, which. Whichever, whomever 连接副词:when, where, how, why二、具体分类1.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。

Who will win the match is still unknown. 谁能赢得这场比赛还不得而知。
