名词性从句讲解在复合句中起名词作用的从句叫做名词性从句。
它包括主语从句、宾语从句、表语从句和同位语从句。
名词性从句是中学阶段的一个重要语法项目, 在历年的高考中几乎都涉及到, 并且每年的命题各有变化。
分析历届高考试题名词性从句考查的焦点主要有以下六个方面1.考查名词性从句的语序问题2.考查引导词that与what的区别3.考查it在名词性从句中作形式主语或形式宾语的用法4.考查whether与if的区别5.考查名词性从句中的疑问词+ever引导的名词性从句与n.matter+疑问词引导的状语从句的区别6.考查名词性从句的虚拟语气问题语法要点剖析一、名词性从句主语从句、表语从句、宾语从句、同位语从句, 在整个句子中所起的作用, 相当于一个名词。
因此, 这四种从句通称为名词性从句。
引导名词性从句的连接词可分为三类:.连接词: that.whether.i.(不充当从句的任何成分).连接代词: what.whatever.who.whoever.whom.whose.which..连接副词: when.where.how.why1.主语从句作句子主语的从句叫主语从句。
主语从句通常由从属连词that,whether,if和连接代词what,who,which,whatever,whoever以及连接副词how,when,where,why等词引导。
that在句中无词义,只起连接作用;连接代词和连接副词在句中既保留自己的疑问含义、又起连接作用,在从句中充当从句的成分。
例如:Wha.h.want.t.tel.u.i.no.clear. 他要跟我们说什么,还不清楚。
I.i.know.t.u.ho.h.becam..writer. 我们都知道他是如何成为一名作家的。
Wher.th.Englis.evenin.wil.b.hel.ha.no.ye.bee.announced.英语晚会将在哪里举行, 还没有宣布。
有时为避免句子头重脚轻, 常用形式主语it代替主语从句作形式主语放于句首, 而把主语从句置于句末。

(完整版)高考英语【名词性从句】专题十名词性从句第一节基本知识与基本概念【什么是名词性从句?】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.【宾语从句】在句子中作宾语的从句就是宾语从句。
由于这是同学们接触比较早的一种从句,应该问题不大。
所以在近年的高考题中,以宾语从句的知识作为考点的题目较少。
但是,宾语从句也有自己的特殊情况,如介词的宾语,形容词的宾语,宾语从句提前和并列的宾语从句等现象。
如:We assumed that there would be more than 100 guests.He told the police in detail what he saw and heard.Nobody is sure what humans will look like in a million years.That will depend on whether they can get the chance.Whether I will have the time I am not sure at the moment.The conductor complained that we were not gifted in singing and that he would never come again.【表语从句】表语从句的最重要脸谱就是它们应该出现在系动词的后面。
