名词性从句
语序：陈述语序
在句中充当主语的从句称为主语 从句。英语中主语从句的句型可分 为两大类： 直接将主语从句放在主语位置上； 用it作形式主语，将真正的主语从 句后移，放在其他成分后。
让我们先说说第一类吧！
一、连接词（只起连接作用，在从句中不充当句子成分）
that：无词义。 e.g.: 他赢得比赛一事在我国引起巨大轰动。 That he won the game made a tremendous stir in our country. whether：“是否”。可单独使用，也可与or或or not连用。 e.g.: 我们明天是否能去春游取决于天气。 Whether we can go for a spring outing depends on the weather. 他们是否会来还未告诉我们。 Whether they will come has not been told to us.
四、主语从句与主谓一致
一个从句作主语时，谓语动词通常用单数形式， 特别是用it作形式主语的句型。 e.g.: Whether this kind of chemicals is better has not been tried.
当what引导主从，应遵循意义一致原则，谓语动 词选用相应形式。表语是复数时，谓语动词用复数 形式。 e.g.: What we do willingly is easy. What they were searching for were the missing gems.
Introduction

句、同位语从句。

名词性从句一、名词性从句包括：主语从句：一个句子做主语，放在句首。
宾语从句：一个句子做宾语，放在动词后面。
表语从句：一个句子做表语，放在Be后面。

比如：He boasted of his success. (boast of + 宾语)He boasted that he was a success. (boast of+宾语从句，省略介词of)但是，有些固定结构中能用介词+that的用法；包括besides/beyond that(这两个都表示除---外), but that(要不是；若非), except that(除去), in that(因为), save that(除---外)的用法：①、She knew nothing besides/beyond that he was there.②、He didn’t really know what he was going to say beyond that the situation demanded something romatic.③、Noting would please him but that we goalong.④、I know nothing except that he left home early that morning.⑤、I prefer his plan to yours in that I think it’s more practical.⑥、I am well save that I have a cold.2、宾语从句中that有时省；有时不能省略：①、当that和主句谓语之间或者从句之间有插入语时，that不能省略：He judged that, because he was a child, he didn’t know wine.②、当that从句和另一名词性从句并列做宾语时，that不能省略：Everyone knows what happened and that he was worried.③、当that从句是双宾语中的直接宾语时，that一般不省略。

名词性从句有哪些
名词性从句有哪些名词性从句共有四种，分别是主语从句（整个从句在主句中做主语），表语从句（整个从句在主句中做表语），同位语从句（整个从句在主句中做同位语），宾语从句四类（整个从句在主句中做宾语）。
名词性从句有哪些1、主语从句例如：It + be + 形容词/名词/动词过去分词 + that 从句It is strangethat he knows nothing about it.从句：He knows nothing about it.主句：It is strange something (= He knows nothing about it).连接词在从句中是否充当成分：否连接词是否可省：否2、宾语从句例如：that 引导的宾语从句I think that English is important.从句：English is important.主句：I think something (= English is important).连接词在从句中是否充当成分：否连接词是否可省：是3、表语从句用法和结构同宾语从句，区别在于：系动词后面所接的从句为表语从句，而及物动词后面所接的从句为宾语从句。
例如：- that 引导的表语从句The truth is that English is important.从句：English is important.主句：The truth is something (= that English is important).4、同位语从句同位语从句就是在复合句中作名词的同位语的名词性从句。
同位语从句对于名词进一步解释，说明名词的具体内容，一般由that引导，同位语从句有时可以不紧跟在它所说明的名词后面，而是被别的词隔开。
名词性从句的三种类型与用法
名词性从句的三种类型与用法名词性从句指的是在句子中充当名词的从句。
在英语中，名词性从句有三种类型，分别是主语从句、宾语从句和表语从句。
它们在句子中扮演不同的角色，起到连接主句与从句的作用。
本文将详细介绍这三种名词性从句的类型与用法。
一、主语从句主语从句在句子中充当主语的角色。
它常常以“that”开头，但也可以用“whether/if”引导。
主语从句位于主句之前，因此有时需要使用it作为形式主语来引导整个句子。
例如：1. That she is talented is obvious.2. Whether he will come to the party is uncertain.在上面的例句中，“that she is talented”和“whether he will come to the party”分别是主语从句。
它们在句子中起到了名词的作用，充当主语。
二、宾语从句宾语从句在句子中充当宾语的角色。
宾语从句通常出现在及物动词、介词或系动词之后。
引导宾语从句的词语包括“that, whether/if, who, whom, whose, which”等。
例如：1. He said that he would come to the party.2. I don't know if she has finished her work.在以上例句中，“that he would come to the party”和“if she has finished her work”分别是宾语从句。
它们充当了及物动词“said”和“know”的宾语。
三、表语从句表语从句在句子中充当表语的角色，说明主语的身份、特征、状态或性质。
表语从句通常以“that, whether/if, who, whom, whose, which”等词语引导。
例如：1. My belief is that honesty is the best policy.2. It is unclear whether he can pass the exam.在上述例句中，“that honesty is the best policy”和“whether he can pass the exam”分别是表语从句。
名词性从句(精华)-个人整理
名词性从句在句中的句法功能相当于名词，在句中充当主语、宾语、表语和同位语。
名词性从句可分为主语从句、宾语从句、表语从句和同位语从句四种。
要点1 主语从句常用的引导主语从句的引导词有从属连词、连接代词和连接副词等。
主语从句作主语时谓语动词用单数。
e.g. What we need is a good rest.Why he left without a word is not known.1.that引导的主语从句当从句中主语、表语或宾语都不缺少，而句子所表达内容完整、意思明确时用that引导主语从句，用来陈述事实。
注：that引导的主语从句若在句首，that不可省略。
e.g. That George and Lucy got married last week was a fact.__B____ fashion differs from country to country may reflect the cultural differences from one aspect.A. WhatB. ThatC. ThisD. Which2.whether / if 引导主语从句当从句中主语、表语或宾语都不缺少，而句子所表达意思不明确时用whether / if引导主语从句，表“是否”。
注：若从句在句首，必须用whether；若从句在句末，形式主语it在句首，用whether / if 都可。
e.g. Whether it is true remains to be seen.It is doubtful whether / if he did it all by himself.3.wh-引导主语从句wh-在句中充当一定的成分，具有一定意义。
连接代词充当主语、宾语或表语；连接副词充当状语。
注：wh-ever与no matter wh-的区别Wh-ever既可以引导名词性从句又可以引导状语从句，而no matter wh-只能引导让步状语从句。

为了强调that引导的主语从句而置之于句首时，that不可省。
①That the driver could not control his car was obvious.②That she was chosen made us very happy.③That he will come is certain.④That he would take the risk is true.⑤That he should have married her isn't surprising.★通常，that引导主语从句时用it做形式主语，把从句置于句尾，此时that有时可省。
例如：①It was obvious that the driver could not control his car.②It made us very happy that she was chosen.③It is certain that he will come.④It is true that he would take the risk.⑤It isn't surprising (that) he should have married her.★如果以that从句为主语的句子是疑问句，就只能用先行词it结构。
