名词性从句复习讲义 高三英语一轮复习
名词性从句复习注意：1.在名词性从句中，连接词的选择要根据从句的句意和上下文来确定。
2.当从句是陈述句时，通常使用连接词that（可省略，但在正式文体中建议保留）；当从句是疑问句时，通常使用whether/if（表示选择或疑问）或连接代词/副词（表示具体的疑问内容）。
3.在宾语从句中，当从句是特殊疑问句时，其语序要调整为陈述句语序。
4.同位语从句与定语从句的区别在于：同位语从句是对前面名词或代词的具体内容的阐述或解释，而定语从句则是对前面名词或代词的修饰和限定。
一、主语从句定义：在句子中充当主语成分的从句。
引导词：that, whether, if, who, whom, which, what, whose, how, when, where等。
使用原则：主语从句通常位于句首，用于描述句子的主要动作或状态的执行者或承受者。
它可以是陈述句、疑问句或祈使句（但祈使句作为主语从句的情况较少见）。
构成：主语从句通常由连接词that（可省略，但当从句中有疑问词或表示否定、强调等意义的词时，通常不省略）或whether/if（表示选择或疑问）引导，后面跟完整的句子结构。
例句：1.What he said made me think deeply.2.Whether he will come or not is still a mystery.3.How we can solve the problem is our main concern.4.That the earth moves around the sun is a well-known fact.5.Whoever breaks the law should be punished.练习题1._____ he said at the meeting surprised us all.A.

名词性从句讲义1
名词性从句讲义一. 名词性从句在句子中起名词性作用的从句叫做名词性从句(Noun Clauses). 名词性从句在句中的作用相当于名词或名词短语, 在复合句中担当主语, 宾语, 表语和同位语等. 因此根据它在句中不同的语法功能可分为: 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种:连接词: that, whether, if (不在从句中做任何成分)连接代词: what, who, whom, which, whose和wh+ever (通常在从句中做主语,宾语,表语等) 连接副词: when, where, why, how以及wh/h+ever(通常在从句中做状语)二.主语从句1.概念: 主语从句是在复合句中充当主语的从句.2.连接词:that只起连接主句和从句的作用,在从句中不担任任何成分,本身没有词义,不可省略whether 连接主句和从句, 在从句中不担任任何成分, 但本身有选择或是否的含义whether与if 区别〔一〕引导宾语从句，一般既可用whether 也可用if。
但1 or not放在whether之后时，只能用whether 不用if。
I don’t know whether or not he will come. 我不知道他是不是回来。
注1：如果or not放在whether所引导的从句句尾，那么可以用if来替换。
I don’t know whether/if he will come or not.我不知道他是不是回来。
2 在强调任意选择时,用whether…or,此时不用if替换whether。
He asked me whether I wanted to go there by train or by bus.他问我是想乘火车还是坐公共汽车去那里。
注：whether和or一起还有“不管〞之意,引导让步状语从句。
Whether he drives or takes the train, he will be here on time.不管开车来还是乘火车来，他都会准时到。
