第一节知识点讲解顾名思义，主语从句在句子中作主语。
有时本身出现在主语的位置上，也有时出于句子结构的考虑退到句子的尾部，前面用形式主语it代替。
从句作主语时，谓语动词一般为单数形式。
如: What I saw was beyond any verbal description.That his hair was turning grey worried him a bit.Why the company denied the contract is still unknown.When and where the government will build a city square is under discussion.It is pretty annoying that a small part of the machine is missing.It remains to be seen whether the new novel will be well received.Tips: 主语从句的that绝对不能省去。
因为句子是不能做主语的，故用that引导。
若去掉则没有了主语，而宾语从句的that可省。
：That he is right is known to all of us.宾语从句：We all know (that) he is right.1. It 作形式主语和it引导强调句的比较It 作形式主语代替主语从句，主要是为了平衡句子结构，主语从句的连接词没有变化。

下面yjbys小编为大家精心整理的高中英语语法名词性从句基础知识点梳理，欢迎大家阅读与学习!一、名词性从句的基本概念在复合句中起名词作用的从句叫名词性从句，包括作主语从句、表语从句、宾语从句和同位语从句。
(1)主语从句就是在复合句中作主语的从句。
主语从句常用that, whether, who, whom, whose, what, which, when, where, how, why, whatever, whoever等引导。
如：Whether he will be able to come remains a question. 他是否来还是问题。
That China is a great socialist country is well known. 众所周知，中国是一个伟大的社会主义国家。
注：为避免头重脚轻，使句子平衡，常用it作形式主语，而将主语从句后置。
如上述第二例常说成：It is well known that China is a great socialist country.但是，由连接代词what, whatever, whoever等引导的主语从句一般不能用形式主语。
如：What he found surprised me greatly. 他的发现使我非常吃惊。
Whoever is finished may rest. 凡是做完工的人都可以休息。
(2)表语从句就是在连系动词之后作表语的从句。
引导表语从句的连接除与引导主语从句的连接词外，还有as if， as though。

It looks as if (though) it is going to snow. 天好像要下雪似的。
高中英语语法名词性从句知识点小结
高中英语语法名词性从句知识点小结在复合句中具有名词的性质的作主语、表语、同位语、宾语的从句叫名词性从句。
因此，我们把主语从句、表语从句、同位语从句和宾语从句这四种从句统称为名词性从句。
当名词性从句要采用陈述句语序。
由一个含疑问意义的连词引起时，必须将该连词放在名词性从句的开头，且该从句语序不能倒装。
一、引导名词性从句的关联词引导名词性从句的关联词大致相同，它们分别是：连词：that, whether, if；关系代词：who, what, which , whom, whose, whatever, whoever, whomever, whichever ；关系副词：when, where, how, why, however, whenever, wherever 。
引导从句时一般不用逗号和主句分开。
详细见下表：1、that从句与wh-关系代词和关系副词引导名词性从句的区别连词that在从句中不作成分，不含疑问意义；而wh-连词在从句中作成分，且含有疑问意义；或what/where从句相当于一个名词后加一个定语从句。
It worried her a bit that her hair was turning grey.她的头发在变白令她有点担忧。
（that在从句中只起引导词作用，不作成分）What caused the accident is still a complete mystery.事故发生的原因仍然是个不解之谜。
（What在从句中作主语）2、that与whether引导名词性从句的区别。
（1）动词doubt表示“怀疑、不知道”解时，肯定句接whether引导的宾语从句；否定句don’t doubt和疑问句Do you doubt要接that引导的从句。
I don’t doubt that he will come soon.我不怀疑他不久会来。
（此处不用whether）Can you doubt that he will win?你怀疑他会赢吗？（此处不用whether）比较：doubt表示“不信”解时，表示强烈的不相信时，在陈述句中可接that从句。
高中英语语法之名词性从句
高中英语语法之名词性从句引导词主语从句主语从句可直接放在句首，也可用形式主语it代替，而将主语从句后置。
that引导的主语从句1）that引导的主语从句置于句首（that此时在从句中不充当任何成分，无含义，只起连接作用，不能省略）That the earth moves around the sun is known to all.注：从句作主语，谓语动词用单数形式。
2）在that引导的主语从句中，常用it作形式主语，that引导的真正的主语从句后置，常见的此类句型有：①It+系动词+形容词+that从句。
常用于这种结构的形容词有：necessary必要的certain明确的right正确的clear清晰的（un）likely（不）可能的possible可能的strange奇怪的obvious明显的natural自然的important重要的It is likely that he can’t come to the meeting.It is obvious that you have made a big mistake.注：Itisnecessary/important/surprising/strange/unthinkable/unbeli evable/incredible that+主语（should）+动词原形+其它。
例：It is necessary that a college student （should）master one or two foreign languages.It is strange that you （should）trust Jane.②It+系动词+名词+that从句。
常用于这种结构的名词有：a pity遗憾a honor荣耀a shame令人遗憾的事a wonder奇迹good news好消息no wonder难怪a fact事实no surprise不奇怪It is a pity that you didn’t attend the lecture yesterday. It is no wonder that you’ve achieved so much success.③It+ be+过去分词+that从句。
