2023届高考英语语法名词性从句精讲之四大从句用法大全讲义
2023年高中英语语法名词性从句精讲之：四大从句用法大全主语从句主语从句的概念：如果一个句子在复合句中充当一个主语，那么这个句子就是主语从句。
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。
主语从句用法：1、主语从句的引导词：主语从句通常由连词that和whether、连接代词或连接副词以及关系代词型what引导：如：That he is still alive is a wonder. 他还活着，真是奇迹。
When we arrive doesn't matter. 什么时候到没有关系。
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。
Whether they would support us was a problem. 他们是否会支持我们还是一个问题。
2、主语从句与形式主语it：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。
这分三种情况：(1)对于以连词that引导的主语从句，通常用形式主语代主语从句：如：It's a pity that he didn't come. 很遗憾他没来。
(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：如：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，通常不用形式主语，总是主语从句放在句首：如：What we need is money. 我们需要的是钱。

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, whether1that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;2whether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;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.1What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.2whatever / 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: WhoeverAnyone who wants to enter into this school must take the exam.WhateverAnything 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;Howthishappenedisnotcleartoanyone. 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+ be + 形容词+ that 从句obvious,true,surprising,good,wonderful,funny,possible,likely,certain,probable,etc. 如：Itiscertainthatshewilldowellinherexam.+ be + 名词词组+ that 从句anhonour,afact,apity,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’sapitythatwecan’tgo.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 ,turnout ;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句：a. Whether they would support us was a problem.b. It was a problem whether they would support us.3主语从句中的否定前移当用it作形式主语,而将主语从句放在句尾时,主语从句中的否定词常要前移至主句中;例如:It doesn’t see m that they are from the same university.It doesn’t appear that we’ll have a sunny day tomorrow.5. 注意：1主语从句在句首时,必须由连接词引导,不能省略这些连接词;误：They should like each other is natural. 正：That they should like each other is natural.2）在It + be + suggested/advised/ordered/requested/ insisted/required 中, that 从句的谓语也应该用“should + 动词原形”的形式, should有时可以省略;主语从句中用陈述语序,后面的谓语动词用第三人称单数. It is suggested that we should do the experiment a second time.3 . 用于It is important / natural / necessary / impossible that...句型中, 主语从句应使用虚拟语气, 用“should + 动词原形”的形式, should有时可以省略;It is important and necessary that we should keep the balance of nature.4“what”引导主语从句时,谓语动词：常与其后的名词作表语一致,且根据句子的语境而定;eg：What you left are only several old books. What you said is of great importance.5）在It is funny, strange, surprising, a pity, a shame, no wonder, etc. + that从句中,有时谓语部分用should + 动词原形,来表达说话者的感情色彩,此时should也可省略;6）语气"It be + adj./n. + that-clause"与强调句型均有It be...that...之类的语言标志,但不同的是:①前者中的that从句是主语从句.若删掉其中的It be和that,则剩余部分不论结构还是语意都不能成为一个句子;但若将后者中的It be和that去掉,则剩余部分的结构和语意仍能构成一个完整的句子.②强调句型译为汉语时可加上"正是……"或"就是……"之类的字眼,而主语从句则不可以.It is surprising that Mary should have won first place.令人惊奇的是玛莉竟然获得了第一名.It is Mary that has won first place.正是玛莉得了第一名.强调6..主语从句的规律：例will he come is not known. 正：When he will come is not known.规律一、主语从句一律用陈述语序,即主语在前,谓语在后;例2. He will not come to the meeting this evening is true.正：That he will not come to the meeting this evening is true.规律二、连词that 在从句中无实际意义,但不能省略;例3. If the meeting will be put off has not been decided yet.正：Whether the meeting will be put off has not been decided yet.规律三、whether 可以引导主语从句,放在句首,但if不能例4. That whether he will help others is a fact.正：That he will help others is a fact.规律四、主语从句中的连词不能重叠使用;例5. When he will come are a puzzle. 正：When he will come is a puzzle.规律五、含主语从句的主句谓语动词多用单数第三人称形式;1. What he needs is that book.2. What he needs are some books.规律六、what 引导的主语从句,可根据表语决定主句动词的单复数形式;规律七、主语从句为了避免头重脚轻现象,用it 做形式主语,而把从句放在后面; That the earth turns around the sun is known to all.It is known to all that the earth turns around the sun./ thathe said at the meeting surprised us. he turned up at the meeting surprised us.2. if / whether _______you go or stay at home won’t make any differences.What a pity _____is _____you didn’t arrive by daylight.A. there, becauseB. it, thatC. he, whenD. that, formatter how/who/what/where/whenWe are ready to do ______ the country wants us to do.A. whatB. whichC. no matter whatD. whateveris a pity that you should miss such a good chance.___ he made an important speech at the meeting was true.A.

高考英语专项复习：主语从句讲解及练习(附答案)
主语从句讲解及练习主语从句一、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.主语从句主要有三类：（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.你想获得奖牌看起来是不可能的。
That you are so indifferent bothers me.你如此冷淡使我很烦恼。
That she survived the accident is a miracle.她在事故中幸免于难简直是奇迹。
（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。
例如：Whether she is coming or not doesn’t matter too much.她来不来都无关紧要。
（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.你所需要的是更多的训练。
What I want to know is this. 我想知道的就是这事。
Whatever we do is to serve the people.我们无论做什么都是为人民服务。
（4）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。
)eg:Where we should leave it is a problem.When they will come hasn’t been made pubic.他们什么时候来还不知道。

主语从句：用作主语的从句叫主语从句。
(Tha t the earth goes around the sun) is known to all.(How this happened) is not clear to anyone.(Whoever comes) is welcome.(When we shall have our sports meeting) is still a question.(Whether he will come today) is still unknown.注意：1.主语从句是特殊疑问句，应该用特殊疑问词加陈述句语序。
2.that引导的主语从句放在句首，不可省略that。
3.主语从句常用it作形式主语，真正的主语放在后面，这时that可省略。
It’s a pity (that) you missed such a good opportunity.It’s still a question when we shall buy the new equipment.It’s still unknown whether he will come or not.4.It is +P.P.+ thatIt + Vi + that It 作形式主语It is said that the president will visit our company.It seems that he has caught a cold.表语从句：用作表语的从句叫表语从句，表语从句放在系动词〔be, remain, seem等〕后The question is whether we should accept their invitation.That was what she said to me.The troubie is that I have lost his address.注意：1.表语从句是特殊疑问句时，应该用特殊疑问词加陈述句语序。

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，whether1）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句：a. Whether they would support us was a problem.b. It was a problem whether they would support us.3）主语从句中的否定前移当用it作形式主语,而将主语从句放在句尾时,主语从句中的否定词常要前移至主句中。
例如: It doesn’t seem that they are from the same university.It doesn’t appear that we’ll have a sunny day tomorrow.5. 注意：1）主语从句在句首时，必须由连接词引导，不能省略这些连接词。
误：They should like each other is natural. 正：That they should like each other is natural.2）在It + be + suggested/advised/ordered/requested/ insisted/required 中, that从句的谓语也应该用“should + 动词原形”的形式, should有时可以省略。
主语从句中用陈述语序,后面的谓语动词用第三人称单数. It is suggested that we (should) do the experiment a second time.3) . 用于It is important / natural / necessary / impossible that...句型中, 主语从句应使用虚拟语气, 用“should + 动词原形”的形式, should有时可以省略。
It is important and necessary that we (should) keep the balance of nature.4）“what”引导主语从句时，谓语动词：常与其后的名词作表语一致，且根据句子的语境而定。
eg：What you left are only several old books. What you said is of great importance.5）在It is funny, strange, surprising, a pity, a shame, no wonder, etc. + that从句中，有时谓语部分用should + 动词原形，来表达说话者的感情色彩，此时should也可省略。
6）语气"It be + adj./n. + that-clause"与强调句型均有It be...that...之类的语言标志,但不同的是:①前者中的that从句是主语从句.若删掉其中的It be和that,则剩余部分不论结构还是语意都不能成为一个句子;但若将后者中的It be和that去掉,则剩余部分的结构和语意仍能构成一个完整的句子.②强调句型译为汉语时可加上"正是……"或"就是……"之类的字眼,而主语从句则不可以.It is surprising that Mary should have won first place.令人惊奇的是玛莉竟然获得了第一名.It is Mary that has won first place.正是玛莉得了第一名.【强调】6..主语从句的规律：例1.When will he come is not known. 正：When he will come is not known.规律一、主语从句一律用陈述语序，即主语在前，谓语在后。
例2. He will not come to the meeting this evening is true.正：That he will not come to the meeting this evening is true.规律二、连词that 在从句中无实际意义，但不能省略。
例3. If the meeting will be put off has not been decided yet.正：Whether the meeting will be put off has not been decided yet.规律三、whether 可以引导主语从句，放在句首，但if不能例4. That whether he will help others is a fact.正：That he will help others is a fact.规律四、主语从句中的连词不能重叠使用。
例5. When he will come are a puzzle. 正：When he will come is a puzzle.规律五、含主语从句的主句谓语动词多用单数第三人称形式。
1. What he needs is that book.2. What he needs are some books.规律六、what 引导的主语从句，可根据表语决定主句动词的单复数形式。
规律七、主语从句为了避免头重脚轻现象，用it 做形式主语，而把从句放在后面。
