That is where Tom used to live. g. That’s why he left. 四、名词性从句语序 名词性从句用陈述句语序。如： 她问我去了哪里 She asked me where I went. II. '()*+$%,-&一、主语从句 1. 由that引导的主语从句&that 引导主语从句时，that 没有意义，但不能省略（that 引导宾语从句时可以省略）。 如：That she is a rich woman is known to us all. 重点 由that引导的主语从句也可以放在先行词it之后, 即用it作形式主语,真正的主语是that 从句。这种主语从句有四种形式： (1) it + be + 形容词 + that从句 (true, clear, certain, obvious, likely, probable, necessary …) It is clear that too much stress is bad for health. (2) it +be +名词词组+that 从句 (a pity, a fact, a wonder, common sense, a question…) It is a pity that he failed the exam. (3) it + 某些不及物动词+ that从句 It happens that … It appears/seems that it’s going to snow. It doesn’t matter that his students don’t have a good foundation, but it matters a great deal to him that they should work hard. It turns out that … It occurred to sb. that … (4) It + be + pp + that … It is said that … (reported, believed, hoped, announced, known, accepted, found, considered, claimed, declared, estimated…) ² it is reported that… 据报道… ² it is said that…据说… ² it is hoped that…有希望… ² it is supposed that… 据推测说… ² it must be pointed out that… 必须指出… ² it is (well) known that… 众所周知… ² it is believed that… 据信… ²it is announced that… 据宣布… 3 / 5 2. 由whether引导的主语从句 (1) 用于先行词 it 作形式主语的结构中 It won’t make much difference whether you go there by bus or on foot. (2) whether 从句置于句首 Whether or not your handwriting is beautiful does not matter. 3. 由what , whatever , which(ever), who , whoever引导的主语从句 Who will win the contest is not clear. Whoever breaks the law is sure to be punished. All these movies are good. Whichever you choose is OK. 4. 由 when, where, how, why 引导的主语从句 When our next concert will be held has not been decided yet. = It has not been decided yet when our next concert will be held. Why he refused my help was unknown. = It was unknown why he refused my help 二、表语从句 表语从句是跟在系动词后面的名词性从句。常用的系动词有be, seem, look, become等。 重点 1. This/That is why … That is why people prefer Debbie to Simon. 2. The reason why... is that...的句式中表语从句不能用because引导。 The reason why people prefer Debbie to Simon is that her body language welcomes people. 三、宾语从句 宾语从句作宾语一般是用于及物动词之后，有时也用于介词之后。 1. 由that引导的宾语从句，在口语中that常常被省略。 a. I think (that) it’s going to rain tomorrow. b. That son of hers doesn’t even know (that) two and two are four. 重点 (1) think, believe, imagine, suppose 等的宾语从句的否定要转移到主句中。 I don’t think (that) he will come. (2) 如果同时有两个that从句作宾语时，第二个that一般不省，以免引起误解。 He denied (that) he had entered the room and that he had stolen the money 难点 带形式宾语it的宾语从句： it是形式宾语，从句才是真正的宾语，其结构为：及物动词+ it + adj./n. + that从句。 verb + it + adj./n + that从句 常见搭配 1. think/consider/find/feel it + adj/n that… 2. take it for granted that… 4 / 5 3. see to it that… 4. make it known that… 5. make it clear that… 6. make it possible that… 7. make it a rule that… 8. depend on it that… I took it for granted that whatever he said was true. We make it a rule that we should wash our hands before meals. I feel it a pity that he won’t be able to join us. 2. 由whether/if引导的宾语从句 whether和if相同，但用法上有一些区别。If只用于宾语从句；whether后面可跟or not而if一般不能；介词后面能用whether，不能用if。 a. He asked me whether he should go there or not. = He asked me whether or not he should go. b. It depends on whether he will support us. 3. 由wh- 疑问词引导的宾语从句 a. The manager asked her she could do and she couldn’t do. b. There are too many kinds of books and I do not know book I should choose. c. Tell me did it. d. Please show us you opened the box. e. She asked me she could find the nearest post office. f. They wanted to know I did it that day. 4. 作介词宾语的从句 1) 介词+wh-从句 a. Nobody showed any interest in what he was saying. b. Whether the fish tastes good depends on how you cook it. c. They were arguing about when they should hold another English evening. d. Do you still have any idea of who called this afternoon. e. Mary are curious about why such things should have happened so often these days. 2) except that（注意：that不能省略） He speaks quite fluent English except that his pronunciation is not satisfactory. 四、同位语从句 当名词性从句跟在某些名词之后作同位语，这种从句叫做同位语从句，用来具体说明名词的内容。同位语从句是放在一个抽象名词后解释说明其内容的从句。 1. 中心词：fact, news, promise, reason, idea, truth, hope, problem, information, suggestion, decision, order, thought, doubt, belief, opinion, explanation, possibility等. a. The fact that light travels faster than sound is known even to school pupils. b. I have the feeling that they will again win the game. 2．引导词： I have no idea that he lost the game. I have no idea why he lost the game.

名词性从句
概念
在复合句中起名词作用的从句叫作名词性从句。
种类

注：由于名词性从句在句中不同的句法功能（即名词性从句在复合句中，能充当主语、宾语、表语、同位语等。），相应地，名词性从句可以分为主语从句、宾语从句、表语从句和同位语从句。
引导词
类别 功能 例词
从属连词 指起连接作用，不充当从句中的任何成分 that, whether, if
连接代词 既起连接作用，本身又作从句的主语、宾语、表语或定语 who, whom, whose, which, what,
whoever, whatever, whichever
连接副词 既起连接作用，本身又作从句的状语 when, where, how, why，whenever，wherever，however
主语从句
主语从句可直接放在句首，也可用形式主语it代替，而将主语从句后置。
that引导的主语从句
1) that引导的主语从句置于句首（that此时在从句中不充当任何成分，无含义，只起连接作用，不能省略）
That the earth moves around the sun is known to all.
注：从句作主语，谓语动词用单数形式。
2) 在that引导的主语从句中，常用it作形式主语，that引导的真正的主语从句后置，常见的此类句型有：
① It+系动词+形容词+that从句。
常用于这种结构的形容词有：
necessary 必要的 certain 明确的

在复合句中起名词作用的从句叫做名词性从句。它包括主语从句、宾语从句、表语从句和同位语从句。名词性从句是中学阶段的一个重要语法项目，在历年的高考中几乎都涉及到，并且每年的命题各有变化。分析历届高考试题名词性从句考查的焦点主要有以下六个方面
1. 考查名词性从句的语序问题 2. 考查引导词that与what的区别
3. 考查it在名词性从句中作形式主语或形式宾语的用法 4. 考查whether与if的区别
5. 考查名词性从句中的疑问词+ever引导的名词性从句与no matter+疑问词引导的状语从句的区别 6. 考查名词性从句的虚拟语气问题
语法要点剖析
一、名词性从句
主语从句、表语从句、宾语从句、同位语从句，在整个句子中所起的作用，相当于一个名词。因此，这四种从句通称为名词性从句。
引导名词性从句的连接词可分为三类：
连接词：that, whether, if （不充当从句的任何成分）
连接代词：what, whatever, who, whoever, whom, whose, which.
连接副词：when, where, how, why
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：

名词性从句
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 happened 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：
