高考英语三大从句讲解+练习(附答案)【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,名词性从句成分为主语从句、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。
1. 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。
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。
主语从句后的谓语动词一般用单数形式。
常用句型如下:(1)It + be + 名词+ that从句(2)It + be + 形容词+ that从句(3)It + be + 动词的过去分词+ that从句(4)It + 不及物动词+ that 从句另注意在主语从句中用来表示惊奇、不相信、惋惜、理应如此等语气时,谓语动词要用虚拟语气“(should) +do”,常用的句型有:It is necessary (important, natural, strange, etc.) that …It is a pity (a shame, no wonder, etc.) that…It is suggested (requested, proposed, desired, etc.) that…注意:连词that, whether在从句中不担任句子成分,只起连接作用,不能省略。
2023年高中英语语法:名词性从句用法详解及强化练习分析名词性从句分类简述名词性从句,就是指其作用相当于名词的从句,它包括主语从句、表语从句、宾语从句和同位语从句。
一、主语从句1. 引导词:主语从句就是在复合句中用作主语的从句,引导主语从句的引导词主要有三类:一是that;二是whether;三是那些可以用作疑问词的词语,如what, who, which, when, where, how, why 等。
如:That we shall be late is certain. 我们要晚了,这是确定无疑的。
What he says is not important. 他说的话并不重要。
Whether it will do us harm remains to be seen. 是否对我们有害还要看一看。
2. 形式主语:有时为了避免句子显得“头重脚轻”,可用it作形式主语放在句首,而把真正的主语放在句末。
如:It’s a pity that he didn’t come. 很遗憾他没来。
It was uncertain whether he could come or not. 他是否会来还不肯定。
这三句句首的it均为形式主语,相应的真主语分别是that he didn’t come / what she did / whether he could come or not。
二、表语从句表语从句就是在复合句中用作表语的从句。
一般说来,可用于引导主语从句的引导词也可用于引导表语从句,如that, what, who, which, when, where, how, why, whether等。
如:My idea is that we should do it right away. 我的意见是马上就干。
That is what he meant. 这就是他的意思。
The problem is how we can find him. 问题是我们如何找到他。
名词性从句名词性从句指在复合句中起名词作用的从句,它在句子中可作主语、宾语、表语或同位语。
名词性从句既是中学英语教学的重点,也是高考考查的热点。
一、名词性从句的分类名词性从句包括主语从句、宾语从句、表语从句和同位语从句。
其连接词有that, if, whether;连接代词who, what, which;连接副词when,where, how, why等。
考查热点一:对主语从句的考查主语从句在复合句中充当主语,它可以放在主句谓语动词之前。
但为了保持句子平衡,多数情况下可用it 作形式主语,而把主语从句置于句尾。
考查热点二:对宾语从句的考查宾语从句在句子中作及物动词或介词的宾语。
如果主句的谓语动词是及物动make, find, see, think等,则把宾语从句置于宾语补足语之后,用 it 作形式宾语。
另外,某些作表语的形容词,如 sure, happy, glad, certain等之后也可以带宾语从句。
考查热点三:对表语从句的考查表语从句在句子中作表语,位于主句中的系动词之后。
一、什么是表语( predicative)在形式上,位于系动词后的就是表语。
从含义上讲,表语是回答主语“是什么”或“怎么样”的语法成分。
即是指“是”字句“是”字后面的成分。
表语就是起表述作用的句子成分。
它修饰的是主语。
表语是用来说明主语的身份、性质、品性、特征和状态的。
表语须和连系动词一起构成句子的复合谓语。
表语常由名词、形容词、副词、介词短语、不定式、动词的-ing、动词的-ed、从句来充当,它常位于连系动词( be, become,appear, seem等)之后。
Albert Einstein was a famous professor of physics.二、不定式、动名词与分词作表语的区别不定式和动名词作表语相当于一个名词作表语,含义是回答主语“是什么”;分词作表语相当于形容词作表语,含义是回答主语“怎么样”。

名词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。
一、引导名词性从句的连接词二.主语从句What he wants to tell us is not clear.Who will win the match is still unknown.Where the English evening will be held has not yet been announced.注意: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。
主语从句后的谓语动词一般用单数形式。
常用句型如下:(1)It + be + 名词+ that从句(2)It + be + 形容词+ that从句(3)It + be + 动词的过去分词+ that从句(4)It + 不及物动词+ that 从句当堂练习:(1)It is immediately clear ____ the financial crisis will soon be over.(2)____ was most important to her, she told me, was her family.(3)watch was lost is unknown.(4)he finished writing the composition in such a short time surprised us all.三、宾语从句We must never think (that) we are good in everything while others are good in nothing.He has told me that he will go to Shanghai tomorrow.(由连接词that引导宾语从句时,that在句中不担任任何成分,在口语或非正式的文体中常被省去,但如从句是并列句时,第二个分句前的that不可省。
)I want to know what he has told you.注意:当think, believe, imagine, suppose等等动词引起的否定性宾语从句中,要把上述主句中的动词变为否定式。
即将从句中的否定形式移到主句中。
例如:We don’t think you are here. 我们认为你不在这。
I don’t believe he will do so. 我相信他不会这样做。
当堂练习:(1)(2)She always thinks of she can work well.(3)She will give四、表语从句The fact is that we have lost the game.That’s just what I want.The reason why he was late was that he missed the train by one minute this morning .当堂练习:(1(2)He has become he wanted to be ten years ago.(3)You are saying that everyone should be equal, and this is ____ I disagree.五. 同位语从句同位语从句说明其前面的名词的具体内容。

The news that we won the game is exciting.I have no idea when he will come back home. 我不知道他什么时候回来。
当堂练习:’science.六、名词性that-从句1)由从属连词that引导的从句叫做名词性that-从句。
That只起连接主句和从句的作用,在从句中不担任任何成分,本身也没有词义。

宾语:John said that he was leaving for London on Wednesday.约翰说他星期三要到伦敦去。

同位语:近来谁也没有见过他,这一事实令办公室所有的人不安。
形容词宾语:I am glad that you are satisfied with your job.你对工作满意我感到很高兴。
2)That-从句作主语通常用it作先行词,而将that-从句置于句末,例如:It is quite clear that the whole project is doomed to failure.很清楚,整个计划注定要失败。
It's a pity that you should have to leave.你非走不可真是件憾事。
用it作形式主语的that-从句有以下四种不同的搭配关系:a. It + be +形容词+ that-从句It is necessary that…有必要……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…从所周知……It has been decided that…已决定……c.

It +不及物动词+ that-分句It appears that…似乎……It happens that…碰巧………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.在自己家里可以随心所欲。
间接宾语:俱乐部将给得胜者设奖。

形容词宾语:I'm not sure why she refused their invitation.我尚不能肯定她为什么拒绝他们的邀请。
介词宾语:That depends on where we shall go.那取决于我们去哪儿。
2)Wh-从句作主语也常用先行词it做形式主语,而将wh-从句置于句末,例如:It is not yet decided who will do that job.还没决定谁做这项工作。
It remains unknown when they are going to get married.他们何时结婚依然不明。
八、否定转移(阅读了解)1) 将等动词后面宾语从句的否定词转移到主句中,即主句的谓语动词用否定式,而从句的谓语动词用肯定式。
I don't think I know you.我想我并不认识你。
I don' t believe he will come.我相信他不回来。
注意:若谓语动词为hope,宾语从句中的否定词不能转移。
I hope you weren't ill. 我想你没有生病吧。
2) 将seem, appear 等后的从句的否定转移到前面。
It doesn't seem that they know where to go.看来他们不知道往哪去。
It doesn't appear that we'll have a sunny day tomorrow.看来我们明天不会碰上好天气。
3) 有时将动名词,介词短语或整个从句的否定转变为对谓语动词的否定。
I don't remember having ever seen such a man.我记得从未见过这样一个人。
(not否定动名词短语having…)在这里,人们不会想到在街上会碰上陌生的人。
(anyone 作主语,从句中的谓语动词不能用否定形式。
)4) 有时状语或状语从句中否定可以转移到谓语动词前。

He was not ready to believe something just because Aristotle said so. (否定because状语) 他并不因亚里斯多德说过如何如何,就轻信此事。
