一．主语从句主语从句是在复合句中充当主语的从句，通常放在主句谓语动词之前或由形式主语it代替，而本身放在句子末尾。
1. It 作形式主语和it引导强调句的It is a pity that you didn't go to see the film.It doesn't interest me whether you succeed or not.It is in the morning that the murder took place.It is John that broke the window.2. 用it 作形式主语的结构(1) It is ＋名词＋从句It is a fact that … 事实是… It is an honor that …非常荣幸It is common knowledge that …是常识(2) it is ＋形容词＋从句It is natural that… 很自然… It is strange that… 奇怪的是…(3) it is ＋不及物动词＋从句It seems that… 似乎… It happened that… 碰巧…(4) it ＋过去分词＋从句It is reported that… 据报道… It has been proved that… 已证实…3. 主语从句不可位于句首的五种情况(1) if 引导的主语从句不可居于复合句句首。
(2) It is said , (reported) …结构中的主语从句不可提前。
例如：It is said that President Jingo will visit our school next week. (right)That President Jiang will visit our school next week is said. (wrong)(3) It happens…, It occurs… 结构中的主语从句不可提前。

名词性从句梳理
名词性从句梳理一、名词性从句梳理基础知识回顾知识讲解主语从句：做主语用的名词性从句，因其在复合句中做主语，又称主语从句，引导主语从句的有连词that ，whether，连接代词who ，what ，which，连接副词when，where，how，why等。
1）从属连词：that，whether等.that 引导主语从句只起引导作用，本身无实际意义，在主语从句中不充当任何成分，但不能省略。
That he will win is certain.他肯定会赢。
Whether he’ll come here isn’t clear. 他是否会来这里还不清楚。
注意: 由that 引导的主语从句有时为了使句子结构平衡, 避免“头重脚轻”, 常用it 作形式主语, 而把从句放在后面。
例如:That he will refuse this piece of advice is impossible.It is impossible that he will refuse this piece of advice.it为形式主语2. That they should like each other is natural.It is natural that they should like each other.这样就构成了下面一些常用句型:1) It is + n. +从句It is a pity/shame that... 遗憾的是……It is a surprise that…令人惊奇的是…It is a fact that……是事实It is common knowledge that……是常识2) It is + adj. +从句It’s certain that…肯定…It is possible that... 很可能……I. 名词性从句的引导词：1.连接词：that、if、whether不作成分无意义“是否”2. 连接代词：who、whom 、whose、what、which 、whoever, whatever作主/宾/表3. 连接副词：when、where、why、how作状语1. The suit fitted him well except ________ the color was a little brighter.2. Eat whichever cake you like and leave the others for _______ comes in late.3. I told him _______ I was surprised at his attitude towards his study.It is known to all that we have been debating on the problem of pollution for decades.8. 这种植物怎样腐烂，为什么会腐烂仍然是个未知数。

名词性从句高考命题趋势复合句包括名词性从句，定语从句，状语从句这三大类。
高考对名词性从句的考查主要集中在以下几点：从属连词that和what的区别；whether和if的区别；名词性从句和定语从句的区别以及各种名词性从句的引导词之间的异同。
语法脉络主语从句（That he is lying makes us sad）Array表语从句(The truth is that he had died)宾语从句(She told me that she was not excited)同位语从句(The fact that he is poor is obvious)考点清单名词性从句链接高考：1. ______ Barbara Jones offers to her fans is honesty and happiness. (2011北京) A. Which B. What C. That D. Whom析：B 。
what 引导主语从句并且在从句中作offer 的宾语。
which 引导主语从句表示在一定的明确范围内加以选择，意为“哪个，哪些”。
that 引导主语从句在从句中不作成分。
因为表语是honesty and happiness, 所以offer 的宾语不能是whom 。
2. The villagers have already known ______ we will do is to rebuild the bridge. (2011江西)A. thisB. thatC. whatD. which析：C 。
句意：村民们已经知道，我们将要做的事是重建这座桥。
know 后面接宾语从句(省略了连词that)，而what 引导的主语从句在宾语从句中作主语。
what 在主语从句中作do 的宾语。

连词whether引导宾语从句。
2. It is generally considered unwise to give a child _____he or she wants. (NMET1997)A. howeverB. whateverC. whicheverD. whenever析：B。
根据句意“一般认为孩子要什么就给什么是不好的。
”可以看出后面的从句应是一个宾语从句，而从句中wants缺少宾语，A. however 和D. whenever是不能作宾语的；排除A和D，whichever 表示“无论哪一个，无论哪些”，应表示一定范围内的人或物，此处没有涉及事物的范围，所以应选B．whatever，表示“无论什么”。

that在句中引导同位语从句，说明news的内容。
since或because不能引导同位语从句。
which引导同位语从句意为“哪个，哪些”，并且在从句中充当一定的成分，而此句空格后面不缺成分，据此也排除定语从句的可能。
