高考英语名词性从句专题复习(讲解+练习)

专题三名词性从句

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。

考查热点四：对同位语从句的考查

同位语从句一般跟在某些抽象名词之后，进一步说明该名词所表示

的具体内容。可跟同位语从句的名词主要有：fact, idea, news, promise, belief, condition, doubt, fear, hope, problem, proof, question, reply, report, suggestion, thought, truth等。

二、对名词性从句的考查应注意以下几点：

考查热点五：考查名词性从句的语序和主从句时态

名词性从句均应用陈述句语序，其时态要保持主从句时态一致性。

考查热点六：从语境和句子结构需要出发，选择合适的连词

（I）连词that和what：that无实际意义，在从句中不充当任何成分，只起连接主从句的作用；如that引导宾语从句，常可省略；如引导主语

从句、表语从句或同位语从句，that不能省略。What引导名词性从句，具有双重功能（既是连词又在句中充当成分），它既可指人，也可指物。用于人时，what=the person(s)that，用于物时，what=the thing(s)that。What 可以引导主语从句、宾语从句或表语从句。

（II）连词whether和if：通常whether和if都可以引导宾语从句；但在引导主语从句、表语从句和同位词从句和介词后面的宾语从句以及

后面跟or not时只能用whether而不能用if。

（III）连词whoever,whatever和whichever：这三个词均可引导主语从句、宾语从句和表词从句，且在句中充当一定的成分。Whoever=no matter who (anyone who); whatever=no matter what (anything that); whichever= no matter which(anything that)/ anyone who.

（IV）考查其它的连接副词

连接副词在主语从句中起连词作用，同时又在从句中充当一定的句

子成分。选用这些连接副词的关键是：所选的这个词必须符合句子的逻

辑要求。

考查热点七：名词性从句中对it的考查

为了保持句子平衡，多数情况下可用it作形式主语或宾语，而把主语从句或宾语从句放到后面。

考查热点八：名词性从句中的强调句型和感叹句

考查热点九：名词性从句中的插入成分

（I）用于陈述句的插入语结构

含think, suppose, guess, say, imagine, expect, believe等动词的插入语，直接疑问放在句子中间，不用逗号隔开。

（II）用于疑问句的插入语结构

含think, suppose, guess, say, imagine, expect, believe等动词的疑问句，后接含疑问词的宾语从句时，要将疑问词放在句首。

考查热点十：名词性从句中的否定转移现象

当主句的主语为第一人称，且主句的及物动词为表示感知的动词，

如：think, suppose, guess, say , imagine, expect, believe等时，常把对宾语从句的否定放在主句中，如主句中的主语是第一人称单数I时，其反意疑问句应跟从句变，并且主句中的否定转移到从句。

考查热点十一：名词性从句中的虚拟语气

在“It is suggested/ required/ ordered/ a pity/ a shame/ no wonder/ necessary/ strange/ …+that从句”结构中，that从句谓语有时用(should)do 这样的虚拟语气形式。

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”。

1.Our plan is to keep the affair secret. 我们的计划是让这件事成为

秘密。（主语和表语是相等的）

2.This beautiful village remains unknown to the rest of the world.

这个美丽的村庄仍未外界所知。（主语和表语是不相等的）

三、不定式和动名词作表语的区别

不定式和动名词作表语虽都是用于回答主语“是什么”的，但二者仍有一

些区别。不定式作表语强调的是一次性、具体的、将要发生的动作；动名词作

表语强调的是一般性、抽象的、经常发生的动作。

His job is to paint the walls. 他的工作是粉刷这些墙

四、现在分词和过去分词作表语的区别

现在分词和过去分词作表语都是用于回答主语“怎么样”的。现在分词说

明主语的特征，过去分词说明主语的状态。

1.This dog is frightening. 这条狗让人害怕。（说明狗的特征）

2.This dog is frightened. 这条狗有些害怕。（说明狗的状态）

五、不定式作表语和不定式表示将来时的区别

不定式作表语用于说明主语“是什么”，和主语之间是可以划等号的，不

定式用来表示将来时态时，表示主语即将要执行的动作，和主语之间是不能划

等号的。

What he wanted to suggest is to cut down the price and increase the

sales. 他想建议的是降价促销。

六、-ing动词作表语和-ing动词用于进行时的区别

动名词作表语说明主语“是什么”，现在分词作表语说明主语是特征。-ing 动词用于正在进行时时，说明主语正在执行的动作。

She is taking care of the children. 她在照料小孩。（说明她正在执

行的动作）

七、过去分词作表语和过去分词用于被动语态的区别

过去分词作表语说明主语所处的状态，过去分词用于被动语态说明主语所

承受的动作。

1.The cup is broken. 杯子碎了。（说明杯子是状态）

2.The cup was broken by Peter. 杯子是被彼得打坏的。（说明杯子承受的动作—被打坏

高中英语定语从句教案

教学过程 一、复习预习 1、对上节课课后作业中的问题进行查漏补缺； 2、导入： e.g. She is a beautiful girl. She is a beautiful girl who drives me crazy. 二、知识讲解 （一）定语从句定义

1、定语从句：在复合句中，修饰某个名词或代词的句子（做这个名词或代词的定语）叫定语从句，定语从句一般放在被修饰的名词或代词后面。 2、先行词：被修饰的名词或代词叫做定语从句的先行词。 3、关系词：用来引导定语从句的词叫做关系词。 关系代词的种类： 关系代词：that, which, who, whom, whose, as 关系副词：when, where, why 4、定语从句结构：先行词+关系词+定语从句。 a、There she saw a wall of water that was quickly advancing towards her. b、In Japan, someone who sees another person making the gesture will think it means money. c、Visitors can go on exciting rides where they can feel what it is like to do the things they have seen their heroes do in the movie. d、Oprah Winfrey is a black woman whose rise to fame is an inspiring story. （二）定语从句分类 限定性定语从句：从句对先行词进行必要的描述或说明，对先行词起修饰限定作用，从句与先行词紧密相连，缺少它则句义显得不完整，一般不用逗号隔开。非限定性定语从句：对先行词进行补充说明，解释，它与先行词关系松散，用逗号隔开。 1、The man who gave me this book is T om .(限定性) 2、T om,who is reading a book ,is my classmate (非限定性) （三）关系代词 1、who指人，在定语从句中作主语。 e.g. The man who is sitting under the tree is a German . 2、Whom指人，在句中做宾语，可省略，但在做介词的宾语是只能用whom,不能用who。关系代词前有介词时不能省略。 e.g. I know the girl (whom) the teacher is speaking to . I know the girl to whom the teacher is speaking . 3、whose, 作定语，可指人或物 e.g. Everyone heplps the child whose parents are dead. They are the lazy students whose homework wasn’t handed in . 4、that 指人或物，多指物，作主语（不能省略）或宾语（可省略） e.g. He is the finest comrade that has helped us . This is a plant that grows in the north . 5、which ,指物，在句中做主语（不能省略），或宾语（可省略）。 e.g. This is a plant which grows in the north . ☆常用that不用which的情况 1、当先行词是all, everything, anything, nothing, much, little, none, one等不定代词时，只用that。 歌诀助记：不定代词这路货，全用that准没错。 Pay attention to everything that I do.

高中英语从句综合讲解

【宾语从句】 在英语中，有简单句(只含一个谓语动词)、并列句(用连词连接，含不止一个谓语动词)和复合句(含从句)。本节课我们复习复合句里面的宾语从句 ．．．．。 如：She knows that he will come back soon. I’m afraid that I can’t go to your party. 1.宾语从句的【引导词】 宾语从句的引导词分三种。 ●(1) 如果从句是陈述句，引导词用that.（that在口语中常省略） 主句：He says... 从句：He is tired of playing computer games. → He says that he is tired of playing computer games. ●(2) 如果从句是一般疑问句，引导词用if/whether，表示“是否”。 主句：I don’t know… 从句：Does Tom likes fish? → I don’t know if / whether Tom likes fish. 【注意】① whether引导的从句常与or not连用，而if不能； ②宾语从句可简化为whether to do的搭配，而没有if to do这种搭配. 如：Could you tell me whether I should finish my homework today or not? Could you tell me whether to finish my homework today? 【拓展】if有两个意思： 1. 表示“是否”，引导的是宾语从句。动词的时态视情况而定。 2. 表示“如果”，引导的是条件状语从句，时态用一般现在时表示将来（遵循“主将从现”规则）。 经典例题：--Do you know if Tom ____________(go) hiking with us ? --I’m not sure. But i f he ____________(go), I will take many photos with him . ●(3) 如果从句是特殊疑问句，直接用该疑问词来引导。 主句：Do you know… 从句：what does he want to buy? → Do you know what he wants to buy? 你知道他想要买什么吗？ 2. 宾语从句的【时态】 ■(1) 当主句是一般现在时，从句根据情况使用任何时态 如：She wants to know if I have finished my homework. 她想知道我是否已经完成了我的作业。 Do you know when he will be back? 你知道他将会什么时候回来？ ■(2) 当主句是一般过去时，从句应使用过去的某时态 如：He said that she was singing. 他说她正在唱歌。 She wanted to know if I had finished my homework. 她想知道我是否已经完成了作业。 Did you know when he would come back? 你知道他将会什么时候回来？ 【注意】格言和客观真理总是用一般现在时。 如：She told me yesterday (that) the earth travels around the sun.

(完整版)高考英语【名词性从句】

专题十名词性从句 第一节基本知识与基本概念 【什么是名词性从句？】 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. 【宾语从句】 在句子中作宾语的从句就是宾语从句。由于这是同学们接触比较早的一种从句，应该问题不大。所以在近年的高考题中，以宾语从句的知识作为考点的题目较少。但是，宾语从句也有自己的特殊情况，如介词的宾语，形容词的宾语，宾语从句提前和并列的宾语从句等现象。如： We assumed that there would be more than 100 guests. He told the police in detail what he saw and heard. Nobody is sure what humans will look like in a million years. That will depend on whether they can get the chance. Whether I will have the time I am not sure at the moment. The conductor complained that we were not gifted in singing and that he would never come again. 【表语从句】 表语从句的最重要脸谱就是它们应该出现在系动词的后面。如： The only question left is how often the workers are paid. His idea for the coming weekend is that we go skating. 【同位语从句】 从脸谱上看，同位语从句最为麻烦。因为它们也是出现在一个名词的后面，起着解释说明的作用。

高考英语定语从句讲解+习题-

在复合句中充当定语的从句叫定语从句。定语从句的作用相当于形容词，用来修饰主句中的某一名词或代词或整个主句，所以，也称作形容词性从句。被定语从句修饰的词叫先行词，定语从句一般紧跟在它所修饰的先行词之后。在先行词和定语从句之间起连接作用的词叫关系词。关系词有关系代词和关系副词两种。 提示：关系词在定语从句中有三大作用 1. 连接作用——连接先行词和定语从句。 I I . 我把我所有的钱都给了她。（连接先特词和定语从句I ） 2. 替代作用——在定语从句中替代从句所修饰的先行词。 a . 住在隔壁的那个人是个名师。（替代） 3. 成分作用——在定语从句中作主语、宾语、定语或状语。 I . 我喜欢传统的中国画。（在定语从句中作主语） 一、关系代词引导的定语从句 引导定语从句的关系代词主要有, , , , 等。它们分别代替前面的先行词，并在定语从句中作主语、宾语或定语。 A． 指人，在定语从句中作主语。 ? 借钱给你的那人叫什么名字？（定语从句修饰先行词） . 谁笑到最后谁笑得最好。（定语从句修饰先行词） , , . 会议主席坐在我右边，他先发言。（定语从句修饰先行词） B． 指人，在定语从句中做宾语。在口语或非正式文体中，可省略或可用来代替，但在介词后面以及在非限制性定语从句中只能用。 . 有些人我们是喜欢的，有些人则是我们讨厌的。（定语从句分别修饰先行词, ） I . 和我一起工作的人都很友好。（定语从句修饰先行词） . , I , . . , I , . 昨晚我在电话里和卡特先生交谈过，他对我们的计划很感兴趣。（非限制性定语从句中不能用代替） , I , . 两个人来到我的办公室，我以前从未见过他们。（在介词后面不用） C． 人、物皆可，做定语，后面要紧跟被修饰的名词，先行词和后面的名词之间往往是从属关系。 . 有些人，他们的脸你永远难以忘怀。（定语从句修饰先行词） I . 我看见一些树的树叶由于空气污染而发黑。（定语从句修饰行词） D． 1．指物，在定语从句中做主语或宾语。做宾语时常可省略。

高考英语名词性从句考点归纳

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.

高考英语状语从句专项训练

专题十一状语从句 状语从句在高考试题中由于其他从句的干扰，以及倒装句，强调句的介入，使得状语从句更为复杂。状语从句是一种副词性从句，通常由一个从属连词或一个起连词作用的词组引导。状语从句 1. 时间状语从句 常见的连词(组)： when, while, as, before, after, once, till, until, as soon as, now that, hardly ...when, scarcely ...when, no sooner ...than等。 可以引导时间状语从句的副（介）词（短语）或名词短语： directly, instantly, immediately, by the time, the moment, the second, the minute, the instant, every time, each time, next time, the last time等。 注意点如下： (1) when, while, as引导的时间状语从句 as表示“当……的时候”，往往和when/ while通用，但它着重强调主句与从句的动作或事情同时或几乎同时发生。when(at or during the time)既可以表示在某一点的时候，又可以表示在某一段时间内，主句与从句的动作或事情可以同时发生也可以先后发生。while强调一段时间，仅表示从句和主句的动作同时发生，并且有延续意义，该从句中的动词一般要用延续性动词，从句中常用过去进行时态或一般过去时态；当when表示a period of time时，两者可以互换。 She came up as I was cooking.(同时) 在我做饭时，她走了过来。 When we were at school, we went to the library every day.(在一段时间内) 当我们在学校时，每天都去图书馆。 While they were watching TV, I was preparing myself for the coming examination. 他们在看电视，而我在为即将到来的考试做准备。 Strike while the iron is hot. 趁热打铁。( 不可用as或when，这里的while意思是“趁……”) (2) before引导状语从句时的常见重点句型 ①It will (not) be ...before ... 还要……才，要不了多久就…… It was (not) ...before ... 过了……才(没多久就……) It was a long time before I got to sleep. 过了好长时间我才睡着了。 It wasn t long before he told me about the news. 没多久他就告诉了我那条新闻。 ②不等……就……；在……之前就…… The telephone rang off before I could answer it. 我还没来得及接电话，电话就挂断了。 ③刚……就…… He hardly entered the room before he heard the telephone ring. 他刚进屋电话铃就响了。

(完整版)高中英语定语从句讲解及练习

高中英语定语从句讲解及练习 定语从句是高中重点知识，也是高考常考点，大家也不容易掌握，这篇文章主要教你关系代词引导的定语从句 关系副词引导的定语从句判断关系代词与关系副词限制性和非限制性定语从句等内容，有例题讲解定语从句在句中做定语，修饰一个名词或代词，被修饰的名词词组或代词即先行词。定语从句通常出现在先行词之后，由关系词（关系代词或关系副词）引出。 关系代词有：who, whom, whose, that, which等。 关系副词有：when, where, why等。 18.1 关系代词引导的定语从句 关系代词所代替的先行词是人或物的名词或代词，并在句中充当主语、宾语、定语等成分。关系代词在定语从句中作主语时，从句谓语动词的人称和数要和先行词保持一致。 1）who, whom, that 这些词代替的先行词是人的名词或代词，在从句中作主语和宾语。例如： Is he the man who/that wants to see you? 他就是你想见的人吗？（who/that在从句中作主语） He is the man whom/ that I saw yesterday. 他就是我昨天见的那个人。（whom/that在从句中作宾语） 2）whose 用来指人或物，（只用作定语, 若指物，它还可以同of which互换）。例如： They rushed over to help the man whose car had broken down.那人车坏了，大家都跑过去帮忙。 Please pass me the book whose （of which）cover is green.请递给我那本绿皮的书。 3）which, that所代替的先行词是事物的名词或代词，在从句中可作主语、宾语等。例如： A prosperity which / that had never been seen before appears in the countryside. 农村出现了前所未有的繁荣。（which / that在句中作宾语） The package （which / that）you are carrying is about to come unwrapped. 你拿的包快散了。（which / that在句中作宾语） 18.2 关系副词引导的定语从句 关系副词可代替的先行词是时间、地点或理由的名词，在从句中作状语。 1）关系副词when, where, why的含义相当于\"介词+ which\"结构，因此常常和\"介词+ which\"结构交替使用。例如： There are occasions when （on which）one must yield.任何人都有不得不屈服的时候。 Beijing is the place where（in which）I was born.北京是我的出生地。 Is this the reason why （for which）he refused our offer?这就是他拒绝我们帮助他的理由吗？ 2）that代替关系副词，可以用于表示时间、地点、方式、理由的名词后取代when, where, why和\"介+which\"引导的定语从句，在口语中that常被省略。例如： His father died the year （that / when / in which）he was born.他父亲在他出生那年逝世了。 He is unlikely to find the place （that / where / in which）he lived forty years ago. 他不大可能找到他四十年前居住过的地方。 18.3 判断关系代词与关系副词 方法一：用关系代词，还是关系副词完全取决于从句中的谓语动词。及物动词后面无宾语，就必须要求用关系代词；而不及物动词则要求用关系副词。例如： This is the mountain village where I stayed last year. 这是我去年呆过的山村。 I'll never forget the days when I worked together with you.我永远不会忘记与你共事的日子。 判断改错： （错）This is the mountain village where I visited last year. （错）I will never forget the days when I spent in the countryside. （对）This is the mountain village （which）I visited last year. （对）I'll never forget the days （which）I spent in the countryside. 习惯上总把表地点或时间的名词与关系副词where, when联系在一起。此两题错在关系词的误用上。 方法二：准确判断先行词在定语从句中的成分（主、谓、宾、定、状），也能正确选择出关系代词/关

高考英语主语从句讲解

高考英语主语从句 定义：用作主语的从句叫主语从句，它是名词性从句之一。主语从句的时态：不受主句的时态影响和限制。引导主语从句的连接词有： 从属连词: that, whether； 连接代词: who (whoever), whom, whose, what (whatever)和which (whichever)； 连接副词: when, where, how和why。 连接词： 1. 从属连词：that，whether 1）that引导主语从句只起引导作用，在主语从句中不充当任何成分，that本身无实际意义，但不能省略。2）whether意为“是否”，放在句首句末皆可。由whether引导的名词从句做主语，表语，介词宾语，同位语时！不可用if代替。 a.That price will go up is certain. b. Whether they would support us was a problem. 他们是否会支持我们还是一个问题。 2. 连接代词who ，what ，which, whatever, whichever, whoever (Who, whom, which, what可以和ever构成合成词，和what一样引导从句，ever起到强调作用。此类主语从句不能用形式主语it引导，它们在句子中担任成分，不能省略，语序为陈述语序，既有疑问含义,又起连接作用,同时在从句中充当各种成分。 Which side will win is not clear. Whoever breaks the law will be punished. Whatever he did is right. Who killed the scientist remains a question. 1）What和that引导的主语从句的区别：that 只起引导作用，不充当任何成分，没有意思。What 不仅起引导作用，还要充当一定成分(主语、宾语或表语)，意思是：“什么”。 What we need is money. That he will come is certain. 2）whatever / whoever的用法（~ever=no matter ~---让步状语从句中） whatever / whoever可以引导主语从句,并在句中作主语、宾语、表语等,不含疑问意义。whatever相当于anything that; whoever 相当于anyone who。例如: Whoever(Anyone who) wants to enter into this school must take the exam. Whatever(Anything that) she did was right. 3. 连接副词when，where，how，why等。既有疑问含义,又起连接作用,同时在从句中充当各种成分。How this happened is not clear to anyone. When he will be back depends on the weather. When we’ll start tomorrow will be told soon. Where the test will be given is not yet decided. 4. 主语从句后置：为了避免主语冗长,句子头重脚轻,经常用it 作形式主语,主语从句放在后面作真正的主语. 例: That we shall be late is certain. -- It’s certain that we shall be late. 1）用it 作形式主语的结构 A. It + be + 形容词+ that 从句 (obvious, true, surprising, good, wonderful, funny, possible, likely, certain, probable, etc.) 如：It is certain that she will do well in her exam. B. It + be + 名词词组+ that 从句(an honour, a fact, a pity, etc）如： It is a pity/shame that... 遗憾的是…… It is a surprise that…令人惊奇的是… It is a fact that… …是事实It is common knowledge that… …是常识 It’s a pity that we can’t go. C. It + be + 过去分词+ that 从句(said, reported, thought, expected, decided, announced, etc。）如：It is said that Mr. Green has arrived in Beijing. D. It + 不及物动词或短语+ that 从句( seem，happen, doesn’t matter ,turn out）。如： It happened that I was out that day. It doesn’t matter whether she will come or not. 2) 对于以连接代词(副词)引导的主语从句,可以使用形式主语代主语从句,也可直接在句首使用主语从
