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no 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, if (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:What he wants to tell us is not clear. 他要跟我们说什么,还不清楚。
It is known to us how he became a writer. 我们都知道他是如何成为一名作家的。
Where the English evening will be held has not yet been announced.英语晚会将在哪里举行,还没有宣布。

这是一个强调句型,"it is/was that..."是固定搭配,"what he said"是被强调部分, 你可以发现去掉"it was that"后, 句子仍然完整。

根据连词and可知,本句需要一个引导主语从句的连接词,该词同时还要能在从句里充当主语。
that不能在句中作成分;it不能引导主语从句;which意为“哪一个”,不符合本句语境。
