名词性从句讲解(2)
名词性从句讲解（2 ）应城市第三高级中学刘琪一．表语从句：在复合句中，位于系动词之后作表语的从句叫表语从句。
引导表语从句的关联词与引导主语从句的关联词大致一样，表语从句位于系动词后，有时用as if引导。
1.that 引导表语从句，无词义，只起连接作用，不可省。
2.联系动词可为be,look,seem,sound,appear等。
3.主语可为名词fact,truth,cause,question,explanation,trouble,assumption,belief等，代词this,that,these,it等。
4.whether 引导表语从句The fact is that we have lost the game.That’s just what I want.This is where our problem lies.That is why he didn’t come to the meeting.It looks as if it is going to rain.China is not what it used to be.The question is whether the enemy is marching towards us。
【注意】1.当主语是reason时，表语从句要用that引导而不是because。
The reason why he was late was that he missed the train by one minute this morning.2.whether可引导表语从句，但与之同义的if却通常不用于引导表语从句。
3.That is why…译为“这就是……的原因”。
其中why引导的名词性从句在句中做表语，该句型通常用于针对前面已经说过的原因进行总结。
That is why you see this woman before you know.That is why I came.区别：①That is why ……与That is the reason why …同义，只不过从语法结构上讲，前者中的why引导表语从句，后者中的why引导定语从句。

(完整版)高中英语语法总结-名词性从句(2)
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。
名词性从句(2)
It is important that…重要的是……It is obvious that…很明显……b. It + be + -ed 分词+ that-从句It is believed that…人们相信……It is known to all that…众所周知……It has been decided that…已决定……c. It + be +名词+ that-从句It is common knowledge that………是常识It is a surprise that…令人惊奇的是……It is a fact that…事实是……d. It +不及物动词+ that-从句It appears that…似乎……It happens that…碰巧……It occurred to me that…我突然想起……七、名词性wh-从句1）由wh-词引导的名词从句叫做名词性wh-从句。
Wh-词包括who, whom,. whose, whoever, what, whatever, which, whichever等连接代词和where, when, how, why等连接副词。
Wh-从句的语法功能除了和that-从句一样外，还可充当介词宾语、宾语补语和间接宾语等，例如：主语：How the book will sell depends on its author. 书销售如何取决于作者本人。
直接宾语：In one's own home one can do what one likes. 在自己家里能够随心所欲。
间接宾语：The club will give whoever wins a prize.俱乐部将给得胜者设奖。
表语：My question is who will take over president of the Foundation. 我的问题是谁将接任该基金会主席职位。

考研英语语法 名词性从句(2)
LECTURE 2 名词性从句本堂目标：熟悉四种名词从句主语从句特征，重点掌握it结构的主语从句与强调句型的区别、宾语从句中的否定后移、名词从句的嵌套结构等，学会快速分析长难句。
基础预习所谓名词性从句，就是把这个句子当作名词使用，并在句子中充当一定的句子成分。
名词性从句一般可在句子中充当主语、宾语、表语和同位语。
于是我们就有了常说的四种名词性从句：主语从句、表语从句、宾语从句和同位语从句。
名词性从句一律都用陈述语气。

一般而言，that从句都借助形式主语it而放在句子后部分去。
复习主语从句时重点注意形式分类常见结构It be+名词+that 从句It is a pity that…可惜的是…It is a fact that…事实是…It is good news that……真实太好了。
