主语从句详解及练习_附答案
高二年级语法要点剖析（李翌洋）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, why1. 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：（1）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。
注意：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：（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 从句另注意在主语从句中用来表示惊奇、不相信、惋惜、理应如此等语气时，谓语动词要用虚拟语气“(should) +do”，常用的句型有：It is necessary (important, natural, strange, etc.) that …It is a pity (a shame, no wonder, etc.) that…It is suggested (requested, proposed, desired, etc.) that…2. 宾语从句名词句用作宾语的从句叫宾语从句。

(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.When the plane is to take off has not been announced .= It has not been announced when the plane is to take off.(但当what引导的主语从句表示“…的东西”时, 一般不用it作形式主语.)错:It is a book what he wants.对:What he wants is a book.另外, 需要注意的是, it作形式主语代替主语从句时, 要注意和as引导的定语从句的区别.试比较：It was reported that the US was under the terrorist attack.As was reported, the US was under the terrorist attack.（2）常见用it作形式主语的复合句结构A. It is +名词+从句It is a fact that… 事实是……It is good news that … ……是好消息It is a question that … ……是个问题It is common knowledge that … ……是常识类似的名词还有：a pity；a wonder；a good thing；no wonder；surprise等.例如：It is a mystery to me how it all happened.It is common knowledge that the whale is not a fish.It is no surprise that Bob should have won the game.It’s a pity that you missed the film.B. It is +形容词+从句It is necessary that … 有必要……It is clear that … 很清楚……It is likely that … 很可能……It is important that … 重要的是……类似的形容词还有：Strange; natural; obvious; true; good; wonderful; possible; unlikely; quite; unusual; certain; evident; worth-while; surprising; interesting; astonishing, etc.例如：It is doubtful whether she will be able to come.It was really astonishing that he refused to talk to you.It is essential that he should be here by the weekend.It seems obvious that we cannot go on like this.It is necessary that you （should）master the computer.It is important that a student learn English well.It is likely that a hurricane will arrive soon.需要注意的是, 这类主语从句中, 谓语动词很多为“（should）＋动词原形”, 即要用虚拟语气.C. It is +过去分词+从句It is said that … 据说……It is reported that … 据报道……It has been proved that … 已证明……It must be pro ved that… 必须指出……类似的过去分词还有：known; estimated; expected; believed; thought; hoped; noted; discussed; required;decided; suggested; demanded; made clear; found out,etc.例如：It is thought that he is the best player.It is estimated that the vase is 2000 years old.It is used to be thought that a new star must be due to a collision between two stars.It has not been made clear when the new road is to be opened to traffic.It is said that he was killed in the earthquake.D. It seems（happened / appears / doesn’t matter / makes no difference / occurred …）that …It seems that they will win the game.It makes no difference whether he will attend the meeting or not.It does not matter if I missed my train.It happened that I saw him yesterday.主从练习1. _____ as much as one-fifth of all timber harvested is not used.A.

AnyoneB. The personC. WhoeverD.Who表语从句1、概述用作表语的从句叫作表语从句, 它位于主句中的连系动词之后.引导表语从句的词有从属连词that、whether、as though(if)；关系代词who, what, which, whom, whose, whatever, whoever, whomever, whichever等；关系副词when, where, why, how, however, whenever, wherever等.可以接表语从句的连系动词由be, look, remain, seem等.That引导表语从句时, 在口语中, 间或可以省略.The trouble is that we are short of money.困难是我们资金短缺.That is why stone walls are used instead of fences around New England fields.这就是为什么在新英格兰用石头墙而不用栅栏的原因.At that time, it seemed as if I couldn't think of the right word anyhow.当时,我似乎怎么也想不出一个恰当的字眼来.2、由从属连词that, whether引导的表语从句.that在引导表语从句时无词义, 而whether有词义, 意为、“是否”.这时主句的主语常常是些抽象名词, 如question(问题), trouble(麻烦), problem(问题), result(结果), chance(可能性), suggestion(建议), idea(想法), reason(理由)等.表语从句对主句主语进行说明、解释, 使主语的内容具体化.The trouble is (that) she has lost his money. 麻烦的事是他丢了钱.The question is whether we need more ice cream.问题是我们是否还需要一些冰淇淋.The problem was that it was too valuable for everyday use.问题是它作为日常之用太贵重了. What she couldn’t understand was that fewer and fewer students showed interest in her l essons. 我们不能理解越来越少的学生对他的课不感兴趣.3、由关系代词引导的表语从句.关系代词who, what, which, whom, whose, whatever, whoever, whomever, whichever等引导表语从句, 在句中作主语、宾语、表语, 关系代词不能省略.The question is which of us should go.问题是我们哪一个应该去.The problem was who could do the work.问题是谁能做这项工作.That's what he is worrying about.那就是他在担心的事.That's what we should do.那是我们应该做的.4、由关系副词引导的表语从句.Go and get your coat.

What; becauseB. What; thatC. That; whatD. That; because［答案］ B［解析］第一个下划线处的引导词引导主语从句并在该主语从句中充当主语, 特指令校方骄傲的事情, 应选用关系代词型的引导词what；第二个下划线处引导表语从句表示原因、理由, 应由that引导对应的名词性从句.［考题6］—Are you still thinking about yesterday’s game?—Oh, that’s ____.A. what makes me feel excitedB. whatever I feel excited aboutC. how I feel about itD. when I feel excited［答案］ A［解析］A选项的意思是“令我感觉激动的事物”；B选项的意思是“我觉得激动的任何事物”；C选项的意思是“我对它感觉的方式”；D选项的意思是“令我感觉激动的时间”.四个选项中A最适合跟代表“game”的主语that对应, 充当表语从句.表语从句与宾语从句的关系不属于的宾语从句和表语从句都属于名词性从句.其作用跟名词在句中的作用相同.故充当宾语的句子叫宾语从句, 充当表语的句子叫表语从句.宾语从句(1)对于宾语从句要掌握以下三点①语序: 从句的语序必须是陈述句语序, 即“主语+ 谓语”这种形式.②时态: 当主句是一般现在时或一般将来时的时候, 从句可以是任何时态, 而当主句是一般过去时的时候, 从句, 从句时态必须是过去时范围的时态, 即(一般过去时, 过去进行时, 过去完成时, 过去将来时).③连接词: 当从句意思完整, 主句意思肯定时, 连接词用that, 且可以省去, 当从句意思完整, 主句意思不确定或含否定含意时, 常用if或whether(是否), 当从句意思不完整时, 连接词则是代替不完整部分的特殊疑问词.表语从句在句子中起表语作用的从句叫做表语从句, 位于主句系动词的后面.表语从句的引导词和主语从句的引导词相同.也是名词性从句的一种.如：What the police want to know is when you enred red the room警察想知道的是你什么时候进的房间.The The trouble is that we are short of funds困难是我们缺乏资金.This This is what we should do这是我们应当做的.That”s s why I want you to work there那就是我要你在那儿工作的原因.His His first question was whether Mr. Smith had arrived yet他的第一个问题是史密斯先生到了没有.注意：从句中的疑问句用正常语序, 即陈述语序.as as if, as though, becau也可用来引导表语从句.She She seems as if she had done a great thing她看起来好像做了一件大事.It It is because you eat too much那是因为你吃得太多了.表从练习一1.

（完整版）主语从句详解
（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.When the plane is to take off has not been announced .= It has not been announced when the plane is to take off.(但当what引导的主语从句表示“…的东西”时, 一般不用it作形式主语.)错:It is a book what he wants.对:What he wants is a book.另外, 需要注意的是, it作形式主语代替主语从句时, 要注意和as引导的定语从句的区别.试比较：It was reported that the US was under the terrorist attack.As was reported, the US was under the terrorist attack.（2）常见用it作形式主语的复合句结构A. It is +名词+从句It is a fact that… 事实是……It is good news that … ……是好消息It is a question that … ……是个问题It is common knowledge that … ……是常识类似的名词还有：a pity；a wonder；a good thing；no wonder；surprise等.例如：It is a mystery to me how it all happened.It is common knowledge that the whale is not a fish.It is no surprise that Bob should have won the game.It’s a pity that you missed the film.B. It is +形容词+从句It is necessary that … 有必要……It is clear that … 很清楚……It is likely that … 很可能……It is important that … 重要的是……类似的形容词还有：Strange; natural; obvious; true; good; wonderful; possible; unlikely; quite; unusual; certain; evident; worth-while; surprising; interesting; astonishing, etc.例如：It is doubtful whether she will be able to come.It was really astonishing that he refused to talk to you.It is essential that he should be here by the weekend.It seems obvious that we cannot go on like this.It is necessary that you （should）master the computer.It is important that a student learn English well.It is likely that a hurricane will arrive soon.需要注意的是, 这类主语从句中, 谓语动词很多为“（should）＋动词原形”, 即要用虚拟语气.C. It is +过去分词+从句It is said that … 据说……It is reported that … 据报道……It has been proved that … 已证明……It must be pro ved that… 必须指出……类似的过去分词还有：known; estimated; expected; believed;thought; hoped; noted; discussed; required;decided; suggested; demanded; made clear; found out,etc.例如：It is thought that he is the best player.It is estimated that the vase is 2000 years old.It is used to be thought that a new star must be due to a collision between two stars.It has not been made clear when the new road is to be opened to traffic.It is said that he was killed in the earthquake.D. It seems（happened / appears / doesn’t matter / makes no difference / occurred …）that …It seems that they will win the game.It makes no difference whether he will attend the meeting or not.It does not matter if I missed my train.It happened that I saw him yesterday.主从练习1. _____ as much as one-fifth of all timber harvested is not used.A.

That; because［答案］ B［解析］第一个下划线处的引导词引导主语从句并在该主语从句中充当主语, 特指令校方骄傲的事情, 应选用关系代词型的引导词what；第二个下划线处引导表语从句表示原因、理由, 应由that引导对应的名词性从句.［考题6］—Are you still thinking about yesterday’s game?—Oh, that’s ____.A. what makes me feel excitedB. whatever I feel excited aboutC. how I feel about itD. when I feel excited［答案］ A［解析］A选项的意思是“令我感觉激动的事物”；B选项的意思是“我觉得激动的任何事物”；C选项的意思是“我对它感觉的方式”；D选项的意思是“令我感觉激动的时间”.四个选项中A最适合跟代表“game”的主语that对应, 充当表语从句.表语从句与宾语从句的关系不属于的宾语从句和表语从句都属于名词性从句.其作用跟名词在句中的作用相同.故充当宾语的句子叫宾语从句, 充当表语的句子叫表语从句.宾语从句(1)对于宾语从句要掌握以下三点①语序: 从句的语序必须是陈述句语序, 即“主语+ 谓语”这种形式.②时态: 当主句是一般现在时或一般将来时的时候, 从句可以是任何时态, 而当主句是一般过去时的时候, 从句, 从句时态必须是过去时范围的时态, 即(一般过去时, 过去进行时, 过去完成时, 过去将来时).③连接词: 当从句意思完整, 主句意思肯定时, 连接词用that, 且可以省去, 当从句意思完整, 主句意思不确定或含否定含意时, 常用if或whether(是否), 当从句意思不完整时, 连接词则是代替不完整部分的特殊疑问词.表语从句在句子中起表语作用的从句叫做表语从句, 位于主句系动词的后面.表语从句的引导词和主语从句的引导词相同.也是名词性从句的一种.如：What the police want to know is when you enred red the room警察想知道的是你什么时候进的房间.The The trouble is that we are short of funds困难是我们缺乏资金.This This is what we should do这是我们应当做的.That”s s why I want you to work there那就是我要你在那儿工作的原因.His His first question was whether Mr. Smith had arrived yet 他的第一个问题是史密斯先生到了没有.注意：从句中的疑问句用正常语序, 即陈述语序.as as if, as though, becau也可用来引导表语从句.She She seems as if she had done a great thing她看起来好像做了一件大事.It It is because you eat too much那是因为你吃得太多了.表从练习一1.

(完整word版)主语从句讲解
主语从句1．定义：用作主语的从句叫做主语从句。
2．引导主语从句的关联词有三类：（1）从属连词that、whether。
如：如:That they were in truth sisters was clear from the facial resemblance between them。
很明显，她们确是亲姐妹，她们的脸型很相似.Whether he’ll come here isn’t clear。
他是否会来这里还不清楚。
从属连词：that， whether等.that 引导主语从句只起引导作用,本身无实际意义，在主语从句中不充当任何成分，但不能省略.由whether及其他连词引导的主语从句放在句首，句后都可. If只能放在句中.造句:1。
、很明显他是个好人.2。
、他通过了考试让妈妈很高兴。
3、天气是否会转晴还不确定。
(3）（特殊疑问词）连接代词who, whom， whose， what, which, whoever， whatever, whichever 如：__________watch was lost is unknown.__________she did is not yet known. 她干了什么尚不清楚.__________side will win is not clear。
__________comes is welcome。
不论谁来都欢迎。
__________ was said has left us much to think。
这里说的话都应当保密.造句：1. 我们需要的是时间。
2。
谁将成为我们的班长还没有决定。
3。
哪本书更好还不知道。
(4) （特殊疑问词）连接副词 where, when, how， why，wherever，whenever，however。

【最新整理，下载后即可编辑】主语从句一、主语从句的连词分三类（1）从属连词引导的主语从句（that whether if）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。
That 引导主语从句通常用it 作形式主语。
That she survived the accident is a miracle.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不能在开头，只能用whether。
Whether she is coming or not doesn’t matter too much.（2）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Whatever we do is to serve the people.注：whatever / whoever的功用whatever = anything that; whoever = anyone who。
要注意和whatever, whoever引导的让步状语从句的区别。
如：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. ）（3）用连接副词when, where, why, how引导的名词性从句(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、it 作形式主语的主语从句有时为了考虑句子平衡，通常在主语从句处使用形式主语it，而将真正的主语从句移至句末。

主语从句一、主语从句的连词分三类（1）从属连词引导的主语从句（that whether if）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。
That 引导主语从句通常用it 作形式主语。
例如：That you will win the medal seems unlikely.That she survived the accident is a miracle.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 不能在开头，只能用whether。
Whether we will hold a party in the open air tomorrow depends on the weather.Whether she is coming or not doesn’t matter too much.（2）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.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。
如：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. ）（3）用连接副词when, where, why, how 引导的名词性从句(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、it 作形式主语的主语从句有时为了考虑句子平衡，通常在主语从句处使用形式主语it，而将真正的主语从句移至句末。
这分四种情况：(1)对于以连词that 引导的主语从句，通常用形式主语it 替代主语从句：<a> It is +名词+从句It is a fact that…事实是……；It is good news that ………是好消息；It is a question that ………是个问题；It is common knowledge that ………是常识类似的名词还有：a pity；a wonder；a good thing；no wonder；surprise 等。
It is a mystery to me how it all happened.It is common knowledge that the whale is not a fish.It is no surprise that Bob should have won the game.<b> It is +形容词+从句It is necessary that …有必要……；It is clear that …很清楚……；It is likely that …很可能……；It is important that …重要的是……类似的形容词还有：strange; natural; obvious; true; good; wonderful; possible; unlikely; quite; unusual; certain; evident; worth-while; surprising; interesting; astonishing, etc.It is doubtful whether she will be able to come.It is essential that he should be here by the weekend.It seems obvious that we can not go on like this.It is necessary that you （should）master the computer.需要注意的是这类主语从句中，谓语动词很多为“（should）＋动词原形”，即要用虚拟语气。
<c> It is +过去分词+从句It is said that …据说……；It is reported that …据报道……；It has been proved that …已证明……；It must be proved that…必须指出……类似的过去分词还有：known; estimated; expected; believed; thought; hoped; noted; discussed; required; decided; suggested; demanded; made clear; found out,etc.例如：It is used to be thought that a new star must be due to a collision between two stars.It has not been made clear when the new road is to be opened to traffic.<d> It seems 不及物动词（happened / appears / doesn’t’t matter / makes no difference /occurred …）that …主语从句不可提前It makes no difference whether he will attend the meeting or not.It does not matter if I missed my train.It happened that I saw him yesterday.(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句：Whether they would support us was a problem. 他们是否会支持我们还是一个问题。
It was a problem whether they would support us.他们是否会支持我们还是一个问题。
(3)对关系代词型what 引导的主语从句，通常直接将主语从句放在句首。
如：What we need is money. 我们需要的是钱。
What I want to know is this. 我想知道的就是这一点。
有时也可将助用形式主语。
如：It is clear enough what he meant. 他是什么意思很清楚。
(4)如果句子是疑问句，则必须用带形式主语it 的结构：Is it true that he is the girl’s father? 他是那女孩的父亲，是真的吗？How is it that you are late again? 你怎么又迟到了？四、连词that 的省略问题引导主语从句的连词that 有时可省，有时不能省，其原则是：若that 引导的主语从句直接位于句首，则that 不能省略；若that 引导的主语从句位于句末，而在句首使用了形式主语it，则that 可以省略：That you didn’t go to the talk was a pity. 很遗憾你没去听报告。
(that 不可省)It was a pity (that) you didn’t go to the talk.很遗憾你没去听报告。
(that 可省)5、6、7、8、9、10、11、12、主语从句练习题1、It never occurred to me you could succeed in persuading him to change his mind.(陕西高考)A．which B．what C．that D．if2、It's obvious to the students they should get well prepared for their future.(天津卷)A．as B．that C．which D．whether3、some people regard as a drawback is seen as a plug by manyothers.(2010·北京)A．Whether B．What C．That D．How4、It is uncertain side effect the medicine will bring about，although about two thousand patients have taken it.(2010·浙江)A．that B．how C．what D．whether主语从句练习题1.makes mistakes must correct them.A.
