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。

〔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〔好象〕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。

Who will go is not important. 〔用波浪线标出从句〕2、用it作形式主语，主语从句放在句末。

It doesn’t matter so much whether you will come or not.〔用波浪线标出从句〕3、that引导主语从句时，不能省略。

That he suddenly fell ill last week made us surprised. 〔用波浪线标出从句〕〔三〕表语从句1、表语从句在复合句中作表语，位于系动词之后。

The question was who could go there. 〔用波浪线标出从句〕2、引导表语从句的连接词that有时可省去。

My idea is (that) we can get more comrades to help in the work. 〔用波浪线标出从句〕〔四〕宾语从句1、宾语从句在复合句中作宾语。

高中英语2025届高考语法复习名词性从句知识讲解

高考英语语法复习名词性从句知识讲解一、什么是名词性从句？名词性从句是指起名词作用的从句。

例如：·I like what I see.(和所有分句一样，名词性分句有一个主语 subject和一个动词verb。

在本例中，该分句的主语是 "I" 动词是"see."）·I know that patience has its limits.(在这个例子中，分句的主语是 "patience"，动词是 "has."）。

将上面的两个例子与下面的例子进行比较：·I like innovation.·I know people.粗体字都是名词nouns。

这证明前两个例子中阴影部分的分句从语法功能上来看就是名词。

很多名词性从句都以 "that"、"how "或 "wh"开头（即 "what"、"who"、"which"、"when"、"where "或 "why"）。

例如：·I know that it happened.·I know how it happened.·I know why it happened.二、如何检查从句是否用作名词检查短语或分句是否用作名词的一个好方法是尝试将其替换为代词（replacing it with a pronoun）。

如果你能做到，那么你的短语或分句就具有名词的功能。

·What I say is true.(代词测试Pronoun test："It is true." 这证明"What I say" 从语法功能上来看是名词。

名词性从句的基本结构与例句 (2)

主语从句
结构特点
主语从句是一个完整的句子作为主语，通常放在句首。
主语从句与主句之间通常用逗号隔开，以保持句子的清晰和连贯。
主语从句可以由陈述句、疑问句或感叹句转化而来。
常见引导词
01
02

that
引导陈述句作为主语从句，无词义，不充当句子成分。
whether/if
引导疑问句作为主语从句，表示“是否”。
在主从复合句中，主句和从句的时态往往需要相互呼应。一般来说，主句是现在时或将来时，从句根据实际情况选择时态；主句是过去时，从句则多用过去
范畴的时态。
当名词性从句表达的是一个客观事实或真理时，从句不受主句时态的限制，只
用一般现在时。
