引导宾语从句的关联词与引导主 语从句表语从句的关联)由连接词that引导的宾语从句
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。 He has told me that he will go to Shanghai tomorrow.
that在从句中无词义，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 成分。 What he wants to tell us is not clear. 他要跟我们说什么，还不清楚。
Who will win the match is still unknown. Where the English evening will be held has not yet been announced.
有时为避免句子头重脚轻，常 用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。主句的谓语动词一般用 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

三、what/whatever与
which/whichever的区别
what/whatever意为“什么/无论什么”，描述的事物在上下 文中没有范围；which/whichever意为“哪个/无论哪个”， 描述的事物在上下文中有范围。 To be honest, I can hardly understand what/whatever you have said. Here is the dress. This is what I have been dreaming of. Here are many beautiful dresses. You can choose whichever you like.

高中英语语法《名词性从句》专题复习教案
高中英语语法《名词性从句》专题复习教案【考点透视】在中学英语中,名词性从句是复合句中构成和分类最为复杂的部分。
根据近年来高考英语命题的走向,今后它将仍然是考查的热点。
其主要考点分布在:名词性从句的语序、名词性从句的连接词的辨析、有关名词性从句的常见句型等。
名词性从句在句中的作用相当于名词,共有四种:主语从句、表语从句、宾语从句和同位语从句。
引导名词性从句的连词有:①连接代词:who,whose,whom,what,which。
②连接副词:when,where,why,how。
③其他连接词:that,whether,if,as if。
注意:①连接代词和连接副词在句中不是疑问词,因此从句中不用疑问式(即不要倒装。
②连接代词和连接副词在句中充当句子成分。
③连接词that,whether,if,as if在句中只起连接作用,不充当句子成分。
(一主语从句主语从句在句中作主语,它可以放在主句谓语动词之前,但是当主语从句太长时,同是把它放在句子后部,前面用it作形式主语,如:It doesn’t matter so much whether you will come or not.你来还是不来,关系不大。
(whether you will come or not是主语从句,it在句中作形式主语(二表语从句表语从句在句中作表语,位于主句系动词之后。
如:That’s why he was late.注意:表语从句还可用as if引导。
如:She looked as if she was going to cry.(三宾语从句宾语从句在句子中作及物动词或介词宾语,在使用宾语从句时有以下几点需要注意:1.时态呼应:当主句谓语动词是过去时态,宾语从句要使用过去时态的某种形式。
2.介词之后的宾语从句,一般不用if或which连接,要用what或whether。
3.whether和if都可以引导动词之后的宾语从句,二者常可互换,但是在正式文体中.或从句中有or not时,只用whether,不用if。
高考英语名词性从句复习课件(共35张PPT)
表语从句 表语从句位于连系动词后。
其基本结构为: 1. My suggestion is that we should go shopping. 2. It looks as if it’s going to rain.
同位语从句在句中作同位语，它一般要放 在主句中某些名词的后面，说明这些名词的含 义。可跟同位语从句的名词主要有： fact, news, promise, reason, idea, hope, word, belief等。
that在同位语从句 与定从句的区别
同位语从句
定语从句
that（连词）只起连接的 that(关系代词) 充当一定的 作用,不充当句子成分 句子成分(主，宾，表）
同位语从句与前面的名 定语从句对先行词起修饰 词是同位关系，表示这 作用，表示“…的”。 个名词的内容
同位语从句的that 一般 而定语从句中的关系代词
4. It depends on _w_h_e_t_h_e_r we will have enough money.
5. W__h_e_t_h_e_rthey can do it matters little to us.

英语高考热点语法名词性从句精讲教案
高中英语语法之名词性从句教案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，名词性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引导名词性从句的连接词可分为三类：连词：that（无任何词意）whether,if（均表示“是否”表明从句内容的不确定性）as if ,as though （均表示“好像”，“似乎”）以上在从句中均不充当任何成分连接代词：what, whatever, who, whoever, whom,whose, whichever,whomever连接副词：when, where, how, why,how many,how much,how often不可省略的连词：1. 介词后的连词2. 引导主语从句和同位语从句的连词不可省略。
That she was chosen made us very happy. We heard the news that our team had won.比较：whether与if 均为"是否"的意思。
但在下列情况下，只可用whether：1. whether引导主语从句并在句首2. 引导表语从句3. whether从句作介词宾语4. 从句后有"or not"Whether he will come is not clear.大部分连接词引导的主语从句都可以置于句末，用it充当形式主语。
It is not important who will go. It is still unknown which team will win the match.二. 主语从句1、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。
高考英语语法专题复习讲义-名词性从句
高中语法精讲—名词性从句了解这样的从句前，我们先回忆下英语中常见的句子成分：主语谓语宾语表语定语状语补语同位语（再念叨一遍：理解英语中的句子成分对于长难句的理解是很有用的，阅读能力会进步飞快）那么问题来了：这些句子成分中，哪些可能是名词呢？换句话说，名词能做哪些成分呢？主语，宾语，表语和同位语是名词最中意的位置啦！如果把名词改为句子，那不就是从句了吗？有名词性功能的句子我们就给个高大上的名字——名词性从句：包括主语从句宾语从句表语从句同位语从句来看个句子：Playing football is interesting.这里动名词做主语。
那按刚才说的，名词改为句子：That we play football together is interesting.that 引导的从句that we play football together在句子中是整个作了主语，所以这句就是主语从句一、名词性从句1、名词性从句中的易错点（1）that的用法。
①主语从句、表语从句、同位语从句中用that但不能省略。
如：That they are good at English is known to us all.The problem is that we don’t have enough money.She expressed the hope that they would come to China one day.②宾语从句中的连接词that有时可省有时又不可省，在以下几种情况中that不能省略：（A）当that从句和主句谓语动词之间有插入词语或者从句主语之间有插入语时，that不可省略；（B）当that 从句与另一名词性从句并列作宾语时，that不能省；（C）当that作介词宾语时，that不可省掉。
如：He judged that,because he was a child, he did not understandwineEveryone knew what happened and that she was worried.The reason lies in that she works harder than the others do.③that从句作主语和宾语时，可以用it 来替换成以下几种结构表达。
高考英语语法一轮复习 名词性从句课件(共51张PPT)
4. It doesn’t matter that you will come or not. whether
e.g. The news that our team has won the final match is encouraging. （从句说明“消息”的内 容：我们队取得了决赛胜利。） The news that you told us is really encouraging. （从句对“消息”加以限定：是你告诉我们的， 而非来自其他渠道。但消息是何内容却不得而 知。）
{I don’t like his job.
宾语 I don’t like what he does every day.
{I don’t know about the man, Mr. White.
同位语 I don’t know about the fact that he is a teacher.
二、当that前面有插入语时，that不宜省略。 Little Alice didn't know, I'm sure, that her sister was going to America. 我确信，小艾丽 斯不知道她的姐姐很快就要去美国了。
三、当that 宾语从句前有 it作其形式宾语时， that不可省略。

适用文档名词性从句解说在复合句中起名作用的从句叫做名性从句。
它包含主从句、从句、表从句和同位从句。
名性从句是中学段的一个重要法目，在年的高考取几乎都波及到，而且每年的命各有化。
解析届高考名性从句考的焦点主要有以下六个方面1.考名性从句的序2.考引 that与 what 的区3.考 it 在名性从句中作形式主或形式的用法4.考 whether 与 if 的区5.考名性从句中的疑+ever 引的名性从句与no matter+ 疑引的状从句的区6.考名性从句的虚气法重点解析一、名性从句主从句、表从句、从句、同位从句，在整个句子中所起的作用，相当于一个名。
所以，四种从句通称名性从句。
引名性从句的接可分三：接： that, whether, if（不充任从句的任何成分）接代： what, whatever, who, whoever, whom, whose, which.接副： when, where, how, why1.主从句作句子主的从句叫主从句。
主从句往常由附属that ，whether ，if和接代what ，who，which ，whatever ， whoever 以及接副 how， when， where， why 等引。
that 在句中无，只起接作用；接代和接副在句中既保存自己的疑含、又起接作用，在从句中充任从句的成分。
比如：What he wants to tell us is not clear.他要跟我什么，不清楚。
It is known to us how he became a writer.我都知道他是如何成一名作家的。
Where the English evening will be held has not yet been announced.英晚会将在哪里行，没有宣告。
有防止句子重脚，常用形式主it取代主从句作形式主放于句首，而把主从句置于句末。
主从句后的一般用数形式。

高考英语 二轮复 习专项 语法课 件：名 词性从 句
有时为避免句子头重脚轻，常用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。主句的谓 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
请判断出下列的句子属于哪种从句：
1.What I want to do is to go shopping.
(主语从句)
2. She had a feeling that she was being waton’t think that he is an honest boy.
高考英语 二轮复 习专项 语法课 件：名 词性从 句
2. 宾语从句
名词句用作宾语的从句叫宾语从句。
引导宾语从句的关联词与引导主语从句表 语从句的关联词大致一样，在句中可以作 及物动词或介词及某些形容词的宾语。
1.由连接词that引导的宾语从句
连接词that引导宾语从句时，句中不担任任何成分，在口语或非 正式的文体中常被省去。但下面情况中不能省略。 （1）that一般不能充当介词宾语,但except,in的宾语。如: He is a good student except that he is a little bit careless. 他是个好学生,就是有点粗心。 其他介词后面需要用that从句作宾语时,必须用it作形式宾语。如: You may depend on it that I shall always help you. 你要相信我会一直帮助你的。

名词性从句由一个主句和一个或一个以上的从句构成的句子叫复合句。
名词性从句在复合句中起名词的作用，它包括主语从句、宾语从句、表语从句、同位语从句四大类，在句中分别用作主语、宾语、表语和同位语。
一、引导名词性从句的关联词A．that连词that本身没有意义，在从句中不担任任何句子成分，在宾语从句中有时可省略。
I hear (that) he has joined the football club. 我听说他已经加入了足球俱乐部。
That light travels in straight line is known to all. 众所周知，光是以直线传播的。
It so happens that I know the man. 碰巧我认识那个。
Is it certain that they will win ？他们一定会赢吗B．whether和if连词whether和if本身有意义（解释是否），在从句中不可省略。
1．whether可以连接所有的名词性从句，而if只能引导宾语从句及主语从句（在主语从句中不能用在句首）。
I didn't know whether he would attend the concert.（宾语从句，可用if代替whether）The question is whether it is worth trying.（表语从句，不可用if代替whether）Whether she comes or not makes no difference.（主语从句，不可用if代替whether）He must answer the question whether he agrees to it or not.。
（同位语从句，不可用if代替whether）2．whether引导的宾语从句可作介的宾语，而if则不能。
It all depends on whether they will support us. (不用if)Ryan was worrying about whether he had hurt her feelings.3.whether后可以接不定式，if 则不能He didn’t know whether to get married or to wait.4.whether 直接可与or not 或or no 连用，if 则不能。
I wonder whether or not he knew the manager.5．if既可引导状语从句，也可引导宾语从句。
如果用if会引起歧义，应避免使用if，而用whether。
Please let me know if you want to join us. 请告诉我你是否想加入我们。
（if引导的从句可被看成是宾语从句，if表示是否）Please let me know if you want to join us. 如果你想加入我们的话，请告诉我一声。
（if引导的从句可被看成是条件状语从句，if表示如果）Please let me know whether you want t join us. 请告诉我你是否想加入我们。
（为避免引起歧义，可用whether表示是否）C．who, whom, whose, what, which连接代词who, whom, whose, what, which等在从句中既起连接作用，同时又担当主语、宾语、定语、表语等成分。
No one knows whom he was waiting for. 没人知道他当时在等谁。
We are worrying about what we should do next. 我们正在为下一步该怎么办而烦恼。
Tell me whose house it is. 告诉我这是谁的家。

D．where, when, how, why连接副词where, when, how, why等在从句中既是连接词，又作状语。
I don't know where we are going to have the meeting.我不知道我们将在哪儿开会。
She always thinks of how she can work well. 她总是在想怎样能把工作做好。
What I am anxious to know is when we can visit the museum. 我急于知道我们什么时候能参观博物馆。
比较：when引导的时间状语从句和名词性从句中的不同时态。
Please let me know when you arrive. 你到的时候，请告诉我一声。
（when引导的是时间状语从句，从句中用一般现在时来表示将来。
）Please let me know when you will arrive. 请告诉我你什么时候到。
（when引导的是宾语从句，从句中用一般将来时。
）E．whoever, whomever, whatever, whichever, whosever连接代词whoever = anyone who任何人, 无论谁；whatever =anything that凡是...，无论什么；whichever = anything that无论那一个, 任何一个；whomever = anyone whom （whoever 的宾格形式）。

比较：连接代词whoever在宾语从句中作主语，whomever作宾语从句中宾语。
You may offer he book to whoever wants it. 你可把这本书给任何想要的人。
（此句中不能使用whomever，因为whoever在宾语从句中作wants it的主语）You may offer the book to whomever you like.你可把这本书给任何你喜欢的人。
（whomever 在宾语从句中作you like的宾语）二、宾语从句在复合句中用作动词宾语或介词宾语的从句叫宾语从句。
A. 作动词宾语He told us（that）he felt ill.Do you know whose dictionary it is ?He has informed me when they are to discuss the work plan.Give a reading list to whoever comes. 给所有来的人一份阅读书目。
注意：doubt（怀疑）的肯定句接if/whether引导的宾语从句，但否定句和疑问句接that引导的宾语从句。
I doubt whether if he will succeed. 我怀疑他是否会成功。
I do not doubt that he can recite the poem. 我相信他能把这首诗背下来。
Do you doubt that he will win 你不相信会获胜吗B．作介词的宾语He was deeply displeased by what had occurred that day. 他对那天发生的事感到很不快。
I am curious as to what he will say. 我很想知道他要说什么。
Your success will largely depend upon what you do and how you do it.They were praised or criticizd according to how they had done their work.He goes to the library every day except when it is raining.注意：that引导的宾语从句只用在少数介词后，如：except, in, but等。
此时，that不能省略。
I know little about him except that he lives downstais. 我对他知之甚少，只知道他住在楼下。
He differed from his classmates in that he devoted his spare time to reading. 他和他的同学们不同的地方在于他把业余时间用在阅读上。
C. 作形容词的宾语I am not sure what I ought to do. 我不能确定我该做什么。
I'm afraid (that) you don't understand what I said. 恐怕你没领会我说的意思。
I'm suprised (that) I didn't see all that before. 我好奇怪，我以前没见过那一切。
D. 用it作形式宾语的情况1．和it作形式主语一样，我们常用it来作形式宾语，把真正的宾语从句放在句末，这种情况尤其出现在带复合宾语的句子中。
(think ,consider make, find )We thought it strange that Xiao Wang did not come yesterday. He has made it clear that he will not give n.。
We consider it necessary that he should improve his pronunciation.We found it stange that he has not come yet.2．由于that引导的宾语从句一般不可以直接作介词的宾语，因此当介词后面需要用that 从句作宾语时，必须使用it作形式宾语。
