[解析与拓展]
1. 在句首加That（并将Light改为light）。that虽无词义但引导主语从句位于句首时不能省略。
2. 将If改为Whether。if, whether都可表示“是否”，但if不能引导位于主句之前的主语从句，它可以引导位于主句之后带有形式主语it的主语从句。
3. 将That改为What。that引导主语从句时无词义。What the professor said 表示“教授所说的”。
4. 将will置于trees之后。主语从句要用陈述句语序。
5. 将No matter who改为Whoever。引导让步状语从句时二者可互换，但引导名词性从句时只能用whoever。
6. 将remain改为remains。主语从句表示单一概念时，谓语要用单数形式。
7. has要改为have。主语从句表示复数概念时，谓语要用复数形式。
8. 将made改为（should） make。在“It is requested / ordered / suggested + that从句”中，从句要用虚拟语气，即谓语用“should + 动词原形”，should 可省略。

主语从句详解及练习-附答案
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： （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。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，在句中可以作谓语动词或介词及非谓语动词的宾语。 1. 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。例如：He has told me that he will go to Shanghai tomorrow.他已经告诉我他明天要去 上海。 We must never think (that) we are good in everything while others are good in nothing. 我们决不能认为自己什么都好，别人什么都不好。
xx考研英语语法复习主语从句
xx考研英语语法复习主语从句 在复合句中充当主语成分的句子叫作主语从句。具体形式为：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。 ⑴陈述句充当主语从句，连词为that(that没有实际含义，在从句中只起连接作用，不在从句中作任何语法成分)，从句为"that+陈述句"，that不能省略。 【例句】 That Chris Lee won the champion of Super Girl in xx arouse wide public concern. 李宇春赢得xx年超女冠军这件事引起了社会的广泛关注。 ⑵一般疑问句充当主语从句，连词为whether(whether"是否"的含义，在从句中只起连接作用，不在从句中作任何语法成分)，从句为"whether+陈述句语序"，whether不能省略。 【例句】 Whether this is true or not remains a mystery. 这是对是错还是个谜。 ⑶特殊疑问句充当主语从句，连词为特殊疑问词(特殊疑问词都有自己的含义，在从句中作一定的语法成分)，从句为"特殊疑问词+陈述句语序"，特殊疑问词不能省略。 【例句】 例1 --what
What caused the aident remains unknown. 是什么引起了这一事故仍然。 例2--where Where my wife and I should enjoy our honeymoon is still unsettled. 我太太和我应该去哪享受我们的蜜月还没有最后决定。 例3 --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4--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5---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6--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讨论。 3.It句型

As many as five courses are provided, and you are free to choose _____ suits you best. A. whatever B. whichever C. whenever D. wherever 1. B。首先把插入语generally speaking删掉。but后的并列分句中，whether he reaches these limits（作为句子主语）will depend on his environment. 2. D。此处it是形式主语，what引导的是主语从句，作真正的主语，what作do的宾语。句意：总统采取什么行动结束这次罢工一点也不清楚。 3. C。宾语从句不缺少成分用that引导。 4. C。首先本句考查的关键短语是promise sb. sth.（向某人承诺某事），本句指的是向参加聚会的人提供一个和电影明星合影的机会，不定式做chance的定语，然后就是参加聚会的任何人（whoever=anyone who）。 5. B。此处it是形式主语，后面whether...or…引导的主语从句是真正的主语，whether...or…意为：是…还是…都行。句意：在这个商店中用现金或信用卡支付都可以。 6. C。根据空后的or可知为“whether … or”短语。
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

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.

表语从句与主语从句
表语从句与主语从句 表语从句和主语从句以及宾语从句都要用陈述语序。 Ⅰ.表语从句 在复合句中，位于系动词之后作表语的从句称为表语从句。它位于主句的系动词之后， 最为重要的是我们应该为牛找到足够的水。 The doubt is who has taken away the valuable vase. （主语，人） 疑点是谁拿走了那只贵重的花瓶。 My topic today is what most scientists are researching.（宾语，物，没有选择范围） 我今天的话题就是大多数科学家正在研究的课题。 The problem is which school will be chosen.(which在从句中作定语) 问题是哪一所学校将被选中。 All this was over twenty years ago，but it’s as if it was only yesterday. 这都是20多年前的事了，但宛如昨天一样。 表语从句中应注意的问题 (1)because，why引导的表语从句。 because引导表语从句时，表示“因为”，why引导表语从句时，表示“……的原因”，相当于the reason why。 That’s because he didn’t understand me. (That’s because...强调原因) 那是因为他不理解我。 That’s why he got angry with me. (That’s why...强调结果) 那正是他对我生气的原因。 (2)what引导的主语从句表示结果或名词reason作主语时，后面的表语从句表示原因时要用that引导，不宜用because。 What cost him his life was that he was too careless. 使他丧命的原因是他太粗心了。 The reason why I was sad/for my being sad was that he didn’t understand me. 我难过的原因是他不理解我。 (3)使用虚拟语气的表语从句 在表示建议、劝告、命令含义的名词后的表语从句中，谓语动词需用“should＋动词原形”表示，should可省略。常见的词有：advice，suggestion，order，proposal，plan，idea，request，requirement等。 My suggestion is that we (should) have a discussion about this matter instead of just laying it aside. 我的建议是我们应当讨论一下这个问题，而不应该把它放在一边。 （4）as if/as though引导的表语从句常置于系动词look，seem，sound，be，become等后面，常用虚拟语气，即形式常用过去式的某种时态。

2016考研英语：主语从句
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。
