名词性从句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。

高中英语真题:名词性从句一、主语从句1．It＋系动词＋形容词(necessary，right，likely，unlikely，wrong，important，certain，clear，obvious，strange，normal等)＋that从句It is certain that most of the farmers have brought in more mo ney by all means.2．It＋be＋名词(短语)(a pity，a shame，good news，a fact，an honour，a wonder，no wonder等)＋that从句It’s no wonder that you’ve achieved so much success.3．It＋be＋过去分词(said，told，heard，reported，decided，suggested，advised，ordered，remembered，thought，considered，wellknown，announced等)＋that从句It is said that the professor has already succeeded in carrying out the experiment.4．It＋特殊动词(seem，appear，happen，matter)＋that从句It happened to me that I had been away when he called.二、宾语从句1．动词的宾语从句有些动词带宾语从句时习惯上需要在宾语从句前加it。

这类动词(词组)有hate，enjoy，like，love，dislike，see to等。

I hate it when they talk with their mouths full.2．一般情况下介词后只能用wh类连接词引导宾语从句。

We are talking about whether we admit students into our club.注意：(1)where引导的从句有时也可用作介词的宾语。

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。

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。

【名词性从句总结表】从句引导词连词关系代词关系副词主语从句that, whether,if(不能放句首) what,whatever,who,whoever,whose,whosever,which,whicheverwhen, whenever, where, wherever, how, however,why表语从句that, whether,because, as, asif, as thoughwhen, where, how, why等宾语从句that, whether,if when, whenever, where, wherever, how, however, why同位语从句that, whether一、主语从句主语从句是指作主语的从句，有三种类型：1．由that引导的主语从句that引导的主语从句是最常见的主语从句，但把that从句放在句首是很少见的，只有为了强调或谓语较长时，that从句才放在句首。

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。

It is no wonder that…难怪…It is common knowledge that……是常识。

Section ⅢGrammar——名词性从句(Ⅱ)与it作形式主语[语境自主领悟]一、连接代词、连接副词引导的名词性从句1．由what, which, who/whom, whose等连接代词和when, where, why, how等连接副词引导的名词性从句在句子中可以充当主语、宾语、表语或同位语。

(1)主语从句What surprised us was her ignorance.使我们吃惊的是她的无知。

Where we will go hasn't been decided.我们要去哪儿还没有定下来。

When she will come is still unknown.她何时来还不知道。

(2)宾语从句The school was built on what used to be a wasteland.这所学校是在以前的荒地上建造的。

Now we don't know how the pyramids were built.现在我们不知道金字塔是如何建造的。

Please tell me whose book it is.请告诉我这是谁的书。

(3)表语从句The problem is how we could make him understand it.问题是我们如何能使他明白这些。

The question is where we should go.问题是我们应该去哪儿。

He was ill.That was why he didn't attend the meeting.他病了。

那就是他没出席会议的原因。

He didn't attend the meeting.That was because he was ill.他没出席会议。

那是因为他生病了。

(4)同位语从句I have no idea where he has gone.我不知道他去哪里了。

模块三Unit1 语法讲解和训练名词性从句一、概述在句子中起名词作用的从句称为名词性从句。

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。

二、名词性从句的引导词1、连接代词：who, whom, whose, what, which, whoever, whatever等2、连接副词：when, where, why, how等3、从属连词: that, whether, if, as if, because (as if, because 只引导表语从句)连接代词和连接副词在句中不再是疑问词，因而从句中用陈述语序。

三、用法详解（一）主语从句1、主语从句用连接代词、连接副词和从属连词that, whether引导。

that不可省略。

That you don’t like him has nothing to do with me.Whether John can do the experiment remains a question.Who will be sent abroad to further his studies is not announced.What surprised me most was that such a little girl can play the violin so well.2、当主语过长时，常常用it作形式主语，而把真正的主语从句放在主句后面。

常用句型有：1)It +be +形容词（true, possible, certain, likely, surprising, strange, important…）+ that从句It’s certain that she will do well in the exam.It’s likely that he will tell me everything about that night.2)It +be +名词词组（no wonder, an honor, a pity, high time等）+that 从句It’s a pity that he can’t come.It’s high time that you turned in your homework.3)It +be +过去分词（said, reported, expected, supposed等）+that 从句It’s said that he is quite self-confident.It’s reported that a letter from the university has reached him.4)It +seem/ happen/look as if等+that从句tIt seems that Alice is not coming.It happened that I was a witness to the accident.5)It +doesn’t matt er(make no difference)+wh-It doesn’t matter whether you know my name or not.It makes no difference to me where we shall have the meeting.（二）宾语从句1、宾语从句用连接代词、连接副词和从属连词that, whether, if引导。

名词性从句1主系表句型----- be （连系动词do）2、主谓宾----- do（vt）3、主谓----- do(vi)----(不及物动词)4、主谓宾补----do(vt)5、主谓宾宾---do(vt) 记双宾语的动词一定要记。

6、There be (不及物动词do)--------be (不及物动词)宾语从句定义：在主谓宾句型的宾语的位置上把做为名词的宾语扩展成一个be句型或者do句型。

可以用下列公式进行表示：主语+谓语+从句。

宾语从句的连词①that ,②whether(or not)或if;③which(whichever), who(whoever)，whom(whomever) ，whose(whosever)，what(whatever);④when(whenever)，where(wherever)，why，how(however); ⑤how many, how much, how long, how often，how soon宾语从句的形式：1、主谓宾句型的宾语从句:做为名词的宾语扩展成一个be句型或者do句型。

He knows the newsHe knows that the teacher is in classroom2, 主谓宾宾---do(vt) 句型的宾语从句，把直接宾语变为一个be或do句型。

He tells me the newsHe tells the news to meHe tells me that she is a teacherHe tells that she is a teacher to me3、主谓宾补句型的宾语从句需要it来做形式宾语I find Chinese important主谓宾补I find that we make a quick decision about this matter important主谓宾语从句补I find it important that we make a quick decision about this matter主谓形式宾语补宾语从句I think it necessary that we take plenty of hot water every day .我认为每天多喝开水是有必要的.I feel it a pity that I haven’t been to the get-together.我没去聚会,感觉非常遗憾.I have made it a rule that I keep diaries.我每天写日记成了习惯.4、宾语从句的省略形式：某些形容词后面可以带宾语从句，其形式为sb+be+形容词+that宾语从句：这一类形容词通常是表示人物的心理，情感等状态的形容词如：sure,certain,glad,please,happy,sorry,afraid,satisfied,surpriseda. I am glad (that) you helped me.b、I am sure (that) you can pass the exam.表语从句同样的道理，如果在主系表句型表语的位置上把表语变成一个be句型或者do句型，则称为表语从句。

LESSON SEVEN名词性从句导言英语从句其实就是三个句型的衍生物。

掌握了三个句型就已经掌握了名词性从句。

名词性从句并不难。

只是在我们过去学过的三种基本句型中出现名词的位置上，根据需要将名词扩大成一个句子，并做小小的改动。

也就是说在一个主系表或主谓宾句型中再套上一个主系表或主谓宾的句子而已。

注意中英文表达上的区别▲由连词that、if、whether 引导的名词性从句主语谓语宾语（宾语从句）每个人都知道地球围着太阳运行。

主语状语谓语宾语（宾语从句）●连词主语谓语状语从上面的例句可以看出，宾语从句只是将宾语扩大成一个句子，并用连词that 引导。

因为that 没有实际意思，通常可以省略。

主语（主语从句）系表语地球围着太阳运行是一条真理。

主语（主语从句）●形式主语系表语主语（主语从句）●It is a truth同样的一个句子，当把它放在主语的位置时，我们便称其为主语从句。

但在英语中为了避免句子头重脚轻，通常将主语从句放在句子的后面，并用it 代替其原先的位置，叫做形式主语。

在这种情况下，连词that 通常不省。

表语（表语从句）●从上面的句子可以看出将一个完整的句子置于表语的位置，便称作表语从句。

主语从句、表语从句以及宾语从句在句子中所占的位置是名词的位置，所以称它们为名词性从句。

由连词if、whether引导的名词性从句也是完整的句子，所不同的是that 在句子中没有实际意思，可以省略，而if、whether因为有是否的意思，故不可省略。

●●I wonder注：whether可加or not而if 不能。

有时我们可以将由whether引导的主语从句放在句首，if则不能。
