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。

它们分为主语从句、表语从句、宾语从句和同位从句。

宾语从句作为复合句中的主句及物动词的宾语，也可以作为介词或某些形容词的宾语。

从属连词包括that、whether、if；关系代词包括who、whom、whose、what、which；关系副词包括when、where、why、how。

这些词既担任成分，又起连接作用。

宾语从句的例子有：I think (that) you will like the pictures。

另外，宾语从句中的时态要与主句呼应，如果主句动词是过去时态，从句则要用相应的过去时态。

如果从句表示的是客观真理、科学原理或自然现象，从句仍用现在时态。

如果主语谓语动词为think、consider、suppose、believe、expect、guess、imagine等，其后的宾语从句若含有否定意义，一般要把否定词转移到主句谓语上，从句谓语用肯定式。

I XXX I was determined to carry out the plan。

I consider it XXX。

高二英语语法名师讲解：名词性从句名词性从句相当于名词，可分别作主句的主语、表语、宾语和同位语。

因此，名词性从句可分为主语从句、表语从句、宾语从句和同位从句。

一、引导名词性从句的连接词1. 连接代词：who，whose，whom，what，which.有词义，在从句中担任成分，如主语、表语、宾语、或定语等。

2. 连接副词：when，where，why，how.有词义，在从句中担任成分，作状语。

3. 连接词：that，whether，if，as if.that 无词义，在从句中不担任成分，有时可省略;if (whether)，as if虽有词义，但在从句中不担任成分。

注意：连接代词与连接副词在句中不再是疑问句，因而从句中谓语不用疑问式。

连接代词与连接副词在从句充当句子成分，连接词whether 和if(是否)，as if(好像)在从句中不充当句子成分，只起连接作用。

根据句义，如果连接代词与连接副词，whether、if 和as if都用不上时，才用that作连接词(that本身无任何含义)。

二、主语从句1. 主语从句在复合句作主语。

e.g. Who will go is not important.2. 用it作形式主语，主语从句放在句末。

e.g. It doesn…t matter so much whether you will come or not.3. that引导主语从句时，不能省略。

e.g. That he suddenly fell ill last week made us surprised.三、表语从句1. 表语从句在复合句中作表语，位于系动词之后。

e.g. The question was who could go there.2. 引导表语从句的连接词that有时可省去。

e.g. My idea is (that) we can get more comrades to help in the work.四、宾语从句1. 宾语从句在复合句中作宾语。

高二语法-名词性从句专讲名词性从句是由if, whether, that 和各种疑问词充当连接词所引导的从句，其功同名词一样。

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。

被强调部分指人是也可用who/whom。

例如：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 happen ed 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。
