高三英语语法复习---名词性从句一、概说名词性从句，即指性质相当于名词的从句，它包括主语从句、宾语从句、表语从句和同位语从句。
名词性从句的连接词的选用依据“从句缺什么成分补什么成分”的原则。
解题时，应首先确定选用连接代词还是连接副词。
然后再根据题意选用具体的连接词。
如果名词性从句中缺少主语、宾语、表语或定语，则选用连接代词。
如果从句中缺少状语，则选用连接副词。
如果从句中不缺成分，而仅表示陈述事实，则用that引导。
如果含有“是否”意义，则选用whether或if。
二、名词性从句的一般引导词1.连接词that 只起连接作用，没有任何意思，也不充当句子成分，在宾语从句中可省略，但引导其他名词性从句时通常不省略。
如：I hope (that) you enjoy your holiday. 希望你假期过得好。
That he likes you is very obvious. 很显然他喜欢你。
2.连接词whether 也不充当句子成分，但有自己的意思，表示“是否”；引导宾语从句时，可换成if，但引导其他名词性从句时不能换成if。
He asked whether [if] I would show him the way. 他问我是否可以给他带路。
Whether it will do us harm remains to be seen. 是否对我们有害还要看一看。
(引导主语从句，不能用if 代替whether)3.连接代词who(m), whose, which, what 等，均有各自的意义，在从句中作主语、宾语、定语等。
如：That’s why she wanted to leave. 这就是她想离开的原因。
When we arrive doesn't matter. 什么时候到没有关系。
Tell me which one you like best. 告诉我你最喜欢哪一个。
4.连接副词when, where, why, how 等，也各自有自己的意义，在从句中作状语。
第05讲名词性从句之主语从句1．了解主语从句的概念和用法。
2．可以根据本节课的内容来完成一些习题。
关于各种从句，有一个浅显易懂的规律：它在句子里面是什么成分，就是什么从句。
比如：▼ 定语从句：作定语的从句I have a dog that is very cute. 我有一只可爱的狗主语谓语宾语定语从句（句中做定语，限定修饰前面的名词dog）▼ 宾语从句：作宾语的从句，放在动词或介词后面I think the dog is very cute.我觉得这个狗很可爱主语谓语宾语从句（句中做think的宾语）▼ 状语从句：作状语的从句I bought a dog because it’s very cute. 我买了一只狗，因为它很可爱主语谓语宾语状语语从句（句中做状语，表原因）那么，主语从句是？聪明的人都能看出来——作主语的呗主语从句结构及用法在句子中担当主语的从句就叫做主语从句，通常放在主句谓语动词之前或由形式主语it 代替，而本身放在句子末尾。
通常结构为“引导词+ 主语+ 谓语+ 其他成分"。
一. 概念：在句子中担当主语的从句就叫做主语从句，通常放在主句谓语动词之前或由形式主语it代替，而本身放在句子末尾。
主语从句使用陈述语序，其通常结构为“引导词+ 主语+ 谓语+ 其他成分", 但当连接代词同时充当从句主语时，其结构为“连接代词+ 谓语+ 其他成分”。
二. 引导词：引导主语从句的词有连词：that, whether, if；连接代词：what, whatever, who, whoever, whom, whomever, whose, which, whichever；连接副词：when, whenever, where, wherever, how, however, why。
答案第1页，共15页1. 连词that, whether, if引导的主语从句that在主语从句中不作成分，没有意思，不能省略；whether和if虽不作句子的成分，但有“是否”的意思，且if引导的主语从句不能位于句首。
名词性从句：that, what, which , whether, if, who, whom, whose,whatever, whichever, whoever, whomever, whoseverwhen, where, why, how …重点起名词性作用的从句, 叫名词性从句。
换言之, 在英语的句子结构中, 本来该由名词充当的主语、宾语、表语和同位语部分, 换由一个句子来充当, 这样的句子就是名词性从句。
名词性从句的定义：名词性从句主语从句( The Subject Clause)宾语从句( The Object Clause)表语从句( The Predicative Clause)同位语从句( The Appositive Clause)连接副词：when 、 why 、where 、 how 、whenever 、wherever 、however引导词从属连词：that 、if 、 whether连接代词 ：who 、 whom 、 what 、 which 、 whose 、 whoever 、 whomever 、whatever 、 whichever引导词分类：从属连词“that”---无词义、不作成份、起连接作用“if”--- “是否 ”、不作成份、起连接作用“whether”---“是否 ”、不作成份、起连接作用名词性从句引导词的用法：连接代词“who”---“谁 ”，作主语、宾语、表语，起连接作用“whom”---“谁 ”、作宾语、起连接作用“what”---“事情 ”、作主语、表语、宾语、定语，起连接作用“whose”---“谁的 ”、作定语、起连接作用“which”---“哪----”、作主语、表语、宾语、定语，起连接作用连接副词“why ”---- “为什么 ”、 作状语、起连接作用“how ”----- “如何 ”、 作状语、起连接作用“where ”-- “什么地方 ”、作状语、起连接作用“when ”-- “什么时候 ”、 作状语、起连接作用考点1 宾语从句在句中起宾语作用的从句称为宾语从句。

名词性从句在句子中起名词作用的句子叫名词性从句(Noun Clauses）。
名词性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．主语从句主语从句是在主句中作主语的句子，它由连接词引导，通常位于谓语动词之前。
1. 连词：在从句中不充当任何成分，常用见的引导主语从句的连词有三个，即that, whether和if.That he got the first prize excited him much. 他获得一等奖一事使他非常兴奋。
Whether you can succeed or not depends on how hard you work at it. 你能否功取决于你努力的程度。
注意：whether引导的主语从句常用置于句首，表示“是否”之意；if引导主语从句时不置于句首。
2. 连接代词：在从句中起名词或代词的作用，常作从句的主语、宾语、表语或定语，有具体意义且不能省略。
常见的连接代词有who, whom, whose, what, which, whoever, whomever, whatever, whichever.What we should do with the problem is undecided. 我们如何处理这上问题还未作出决定。
3. 连接副词：在从句中起副的作用，常作从句的状语，表示时间、地点、原因、方式等。
常见的连接副词有when, where, how, why, whenever, wherever, however等。
How they will solve the serious problem has not been decided. 他们将如何解决这个严重的问题还没有决定。
Why he did that wasn’t quite clear. 他为什么做那件事还不十分清楚。
