(完整版)高中英语语法总结-名词性从句

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.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。

主语从句: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。

而it引导的强调句则是对句子某一部分进行强调,无论强调的是什么成分,都可用连词that.被强调部分指人时也可用who/whom。
