高中英语语法：主语从句的考点分析与专项训练

高中英语语法主语从句 第一节主语从句 1．考点解析。 1．主语从句一般分为三类：由what等代词引导的主语从句；由连词that 引导主语从句，多数情况下由it作形式主语，that从句放到句子后面去；由连接代词或连接副词（或whether）引导的主语从句。 What they are after is beauty. It is not your fault that we can’t arrive on time. When they will arrive has not been decided. 2. 由关系代词what引导的主语从句，也可由whatever（“所…的一切”）或 whoever（“一切…的人”）引导。 Whatever he wants is your support. Whoever comes will be welcome. 3. 大多数主语从句都可用it代替，作形式主语，把主语从句放在句尾。要注意it代替主语从句和it引导的强调句的区别。强调句的结构是it is/was….+that…，强调人是可把that 换做who，whom，whose。如强调的是状语时，也只能用that,而不能用when, where, how, why等。 It was in Paris that they fell in love with each other. It is the lady who was my English teacher. It was last semester that he won the first prize. 2. 试题详解。 1．______ he needs is more experience. A. Who B. That C. What D.

名词性从句之主语从句讲解

名词性从句---主语从句 1. What is needed for the space trip is careful preparation. 2. Her wish is that she can lose weight soon. 3. I think that woman can reach every high achievements in many fields of science. 4. We were very excited at the news that our team had won. 引导名词性从句的关联词可分为三类： 一．从属连词：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二．连接代词：what, who, whom, which，whose, whatever, whoever, whichever(作主宾表定) 三．连接副词：when, where, how, why(作状语) I.主语从句 1.定义：在句子中担当主语的是一个从句,这个从句就叫做主语从句。 2.位置：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。 3.引导主语从句的关联词： (1)从属连词that,whether,if (在从句中不充当成分，仅起连接作用) That Jack won the match yesterday surprised us. Whether he’ll come here isn’t clear. (此处不能用if) (2)连接代词who, whom, whose, what, which, whoever, whatever, whichever(充当主宾表定) What she did is not known. Whoever comes is welcome. (3)连接副词where,when,how,why(在从句中充当状语) How this happened is not clear to anyone. When the meeting will be held is decided by our manager. 4.有时为了避免头重脚轻，常用it作形式主语，而把真正主语放在句子末尾。 How the book will sell depends on its author. = It depends on its author how the book will sell. That he is the best student in the class is obvious. = It is obvious that he is the best student in the class. 用it作形式主语的几种常见结构： (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… It ap pears that… 似乎… (4) It ＋过去分词＋从句

从句归纳区分定语从句、宾语从句、同位语从句

从句小结 从句总述： 从句有主语从句、表语从句、宾语从句、同位语从句、定语从句和状语从句6类。 由于主语从句、表语从句、宾语从句及同位语从句在句子的功用相当于名词，故而这4种从句又通称名词性从句。 1.主语从句（Subject Clause）：用作主语的从句叫主语从句。引导主语从句的关联词有从属连词、疑问代词、疑问副词、缩合连接代词、缩合连接副词等。 2.表语从句（Predicative Clause）：用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都一样。 3.宾语从句（Object Clause）：在句子中起宾语作用的从句叫做宾语从句.宾语从句分为三类:动词的宾语从句,介词的宾语从句和形容词的宾语从句. 4. 同位语从句（Appositive Clause）：在复合句中用作同位语的从句叫同位语从句。它一般跟在某些名词后面，用以说明该名词表示的具体内容。其关联词多为that。 状语从句还可以分为条件状语从句、原因状语从句、方位状语从句和时间状语从句等。 宾语从句 学习宾语从句要抓住三要素：时态、语序、连接词。 一：时态和语序 1·主句用一般现在时，从句可用任意时态。 2·主句用过去时，从句用过去某个时态。 3·主句用过去时，从句是真理时，只用一般现在时。 语序：宾语从句只能用陈述句语序，坚决不能用疑问句语序。 二：连接词 ①从属连词 连接宾语从句的从属连词主要有that，if，whether. that引导表示陈述句的宾语从句,而if和whether引导表示“是否”的宾语从句. 例句： He told that he would go to the college the next year 他告诉我他下一年上大学. I don’t know if there will be a bus any more. 我不知道是否还会有公交车. ②连接代词 连接代词主要有who, whom ,whose ,what ,whoever ,whomever ,whosever, whatever, whichever等. 连接代词一般指疑问,但what, whatever除了指疑问外,也可以指陈述. 例句： Do you know who has won Red Alert game 你知道谁赢了这一局红警游戏吗 ③连接副词 连接副词主要有when,where,why,how,whenever,wherever,however等. 例句： He didn’t tell me when we should meet again. 他没有告诉我什么时候我们能再见面.

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

(完整版)主语从句详解

主语从句详解 一、概述 在句子中起名词作用的各种从句统称为名词性从句.根据它们在句中的语法作用, 这类从句又可分为主语从句、同位语从句、表语从句和宾语从句. 二、主语从句主要有四类 （1）由连词that引导的主语从句:引导词that无含义/在句中不做成分/不可以省. 例如：That you will win the medal seems unlikely. That you are so indifferent bothers me. That she survived the accident is a miracle. （2）用连词whether 引导的主语从句: whether有含义(是否)/在句中不做成分/不可以省. 注意：引导主语从句, 不能用if, 只能用whether. 例如：Whether we will hold a party in the open air tomorrow depends on the weather. Whether she is coming or not doesn’t matt er too much. （3）用连接代词引导的主语从句 在由连接代词who, whose, whom, which, what, whoever, whomever, whichever, whatever引导的名词性从句中, 其连接代词在句中起名词性作用, 担当一定成分. 例如：What you need is more practice. What I want to know is this. Whatever we do is to serve the people. 注：whatever / whoever的功用 whatever, whoever在主语从句中不含疑问意义.它引导主语从句, 并在从句中作主语、宾语、表语等. whatever = anything that; whoever = anyone who.要注意和whatever, whoever引导的让步状语从句的区别. Whoever breaks the law should be punished. （主语从句） （＝Anyone who breaks the law should be punished. ） Whoever breaks the law, he should be punished. （让步状语从句） （＝No matter who breaks the law, he should be punished. ） （4）用连接副词when, where, why, how引导名词性从句(其连接副词有含义,在句中作状语.) 例如:Where we should leave it is a problem. When they will come hasn’t been made pubic. 三、注意点: it构成的主语从句 （1）由连词that引导的主语从句, 在多数情况下放到句子的后面, 而用代词it作形式主语. 例如：That light travels in straight lines is known to all. =It is known to all that light travels in straight lines.

主语从句可以按其引导词的不同分为三类：

主语从句可以按其引导词的不同分为三类： 第一类,用从属连词that引导的主语从句,例如：That we shall be late is certain. That the driver could not control his car was obvious. 这种结构主要是对that从句的内容进行强调,属正式文体,连词that不可以省略；但是在一般情况下,往往使用先行it结构,即用it作形式主语,而把that从句放到后面,这时,在口语中,连词that 有时则可以省略.所以上述两句可以改为： It is certain that we shall be late. It was obvious that the driver could not control his car. 如果整个句子是疑问形式,就只能用先行it结构,例如： Is it true that he would take the risk?

Is it possible that they will come tomorrow? 常使用先行it结构,用that从句作主语的句子有下列几个句型： 1、It + be + 形容词+ that从句： It is clear that he was telling the truth. It’s probable that we’ll be a little late. 2、It + be + 名词词组+ that从句： It’s a pity that you can’t go with us. 3、It + 及物动词+ 宾语+ that从句： It worried her a bit that her hair was turning grey. It shocked me that Peter didn’t tell anybody where he was. 4、It + be + 过去分词+ that从句： It is said that he has been there many times. 5、It + seem/happen/appear等不及物动词+

主语从句与宾语从句

主语从句与宾语从句 一、名词性从句是四位从句的总称：主语从句、宾语从句、同位语从句、表语从句。这些从句都起到类似于名词的作用。 主从：一个句子充当大句子的主语，就叫主语从句。例如； What I need is money.(主语是What I need作大句的主语) It was not obvious that water is fundamental to the development of life.（It是形式主语，真正的主语是that 从句。） 主语从句的位置有两种，一种是放于句首；一种是用It 作形式主语，从句被放后面。 二、宾语从句：一个小句子充当大句子的宾语。 He asked me how old I was . She took it for granted that I’d be back home an hour ago.（It 作形式宾语，真正的宾语是后面的that从句。） 考点一：语序 What I want to do is to go home immediately.陈述语序。 I asked where the famous restaurant was .陈述语序。 名词性从句的语序应该是陈述句语序。 删除疑问语序（be /助动词、情态动词+主语） 考点二：引导词 That（没成分） That the earth moves around the sun is known to all.(that 引导的句子作大句子的主语，that不能丢。) Whether /if （有时互换，主语从句只能用wheather引导，不能用if .可用if 的地方都能用wheather。） Whether the meeting will be put off depends on the weather . 疑问代词：what,who, whom,which,whose 在从句中有成分 What he has is just money.（在从句中有成分作宾语） 疑问副词：where ,when,why,,how在从句中有成分 Why he didn’t attend class is not know yet. That：引导名词性从句时无成分，无词义，有时可以省略。 Whether /if引导名词性从句时无成分，是否。 特殊疑问代词：主，宾，表，定。 疑问副词：状。 考点三：no matter+疑问词（what）VS疑问词（what）+ever Whatever he says must be put down . No matter what he says/Whatever he says,I will not change my mind. 意思相同，但语法不一样。第一句主从，第二句让步状语从句。以ever开头的引导主从或者状语从句，而以no matter 开头的不能引导名词性从句，只能引导状语从句，所以选ever 就一定对。 考点四：建议、命令、要求类+宾从 The doctor suggested that an operation (should)be done immediately on the patient. 初中讲过当主句是一般过去时态的宾语从句：主过去，从句也过去。当主句的动词是建议、命令、要求类的动词时，后面的宾从必须是should+动词原形且should可以省略。此时不管。主语是谁，不管主句是什么时态都不能改变动词是原形的要求.once表示建议、命令、要求类的动词suggest,advise,propose,demand,require,insist,request,ask,command,order后面如果后

在句子中起名词作用的句子叫名词性从句。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、同位语等，因此根据它在句中不同的语法功能，名词性从句又可分为主语从句、宾语从句、表语从句和同位语从句。今天我们就来重点讲一下其中的主语从句。 在复合句中充当主语成分的句子叫作主语从句。它的具体表现形式是：引导词引导一个从句作主语；或者it作形式主语+谓语/系表结构+引导词+从句。 【例1】that That Chris Lee won the champion of Super Girl in 2005 arouse wide public concern.李宇春赢得2005年超女冠军这件事引起了社会的广泛关注。 【例2】what What caused the accident remains unknown.是什么引起了这一事故仍然未知。 【例3】where Where my wife and I should choose to continue my further education is a question of great importance.我太太和我应该去哪享受我们的蜜月还没有最后决定。 【例4】which Which university I should choose to continue my further education is a question of great importance.我应该考哪个大学的研究生是个很重要的问题。 【例5】when When and where the test will be given is not yet decided.什么时候在什么地方进行考试还没定下来。 【例6】-ever Whoever gets the job will have a lot of work to do.任何得到这份工作的人都将要有很多工作要做。 【例7】how How we can protect the grain from damp needs to be discussed.我们怎样才能保护粮食不受潮需要讨论。 【例8】whether Whether this is true or not remains a mystery.这是对是错还是个谜。 It句型 有的时候主语从句过长，根据人类短暂记忆规律，主语过长会影响理解和阅读，往往会用it作形式主语，而把真正的主语放在句尾，加以强调，是为it句型。 【例】 It is a pity that we won’t be able to go to the south to spend our summer vacation.我们不能去南方度过我们的暑假很遗憾。 为表示强调，常以形式主语it引导从句。It+谓语+引导词+从句。由于主语从句一般被认为是单数形式，形式主语代表真正的主语，因此要用it。因此形式主语的谓语动词、be动词+表语均为第三人称单数形式或过去式。 英国桂冠诗人约翰·梅斯菲尔德说：“快乐的日子使人睿智。”很多考生可能觉得这句话应该反过来说，但其实复习过一段时间以后，面对着越来越复杂的难题，你就会发现，保持快乐的心态，复习效率自然而然就会提高。

写作：形式主语从句是雅思写作中非常常用的一种句型

形式主语从句是雅思写作中非常常用的一种句型。我们先来看一下它是如何构成的。(That + 一个完整的句子可做主语)。比如说：(That education is important) is clear.这就是主语从句的基本形式。但如果句子要是这样，主语过长。所以，我们习惯于用it来代替原来的主语。而把原来的主语放在句子的最后。这句话可改为：It is clear that education is important.这就叫做形式主语从句。 以下的形式主语从句句型在雅思写作中都常常用到。希望大家能认真掌握，灵活使用。 1 It is often the case that 2 It’s a fact that 3 It seems that 4 It’s said that 5 It’s reported that 6 It’s believed that 7 It’s universally accepted that 8 It’s announced that 9 It’s estimated that 10 It must be admitted that 11 It’s obvious that 12 It must be stressed out that 13 It is widely-accepted that 14 It cannot be denied that 15 It can be foreseen that 16 It’s as clear as crystal that
