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。

“It is/was + necessary/important/surprising/strange/unbelievable/obvious…+从句”结构中,从句谓语动词用“should+动词原形”,should可以省略It + is/was + 名词 +从句我们的希望是,我们都能通过考试。
It + is/was + V-ed +从句据宣布,该计划已经顺利通过。
“It is/was + suggested/advised/ordered/insisted/required/demanded…+从句”结构中,从句谓语动词用“should+动词原形”,should可以省略It + is/was + 特殊动词 +从句(happen,occur,seem,appear…)你似乎不同意这个计划。
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, 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: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。

不能省略。
That he will win is certain.他肯定会赢。
他肯定会赢。
他肯定会赢Whether he’ll come hereisn’t clear. 他是否会来这里还不清楚。
是否会来这里还不清楚。
注意: 注意由that 引导的主语从句有时为了使句子结构平衡, 头重脚轻” 子结构平衡避免“头重脚轻”, 常用 it 作形式主语, 而把从句放在后面。
例如: 主语而把从句放在后面。
例如 1. That he will refuse this piece of advice is impossible. It is impossible that he will refuse this piece_______________________________________ of advice._______________________________________*it为形式主语为形式主语2.That they should like each other is natural. It is natural that they should like each other._____________________________________这样就构成了下面一些常用句型: 这样就构成了下面一些常用句型 1) It is + n. +从句从句 It is a pity/shame that... 遗憾的是遗憾的是…… It is a surprise that…令人惊奇的是令人惊奇的是… 令人惊奇的是It is a fact that… …是事实是事实It is common knowledge that… …是常识是常识 It is a pity that 很遗憾)we lost the match. *_______________(很遗憾很遗憾 It is a fact that 这是事实)he cheated in the *______________(这是事实这是事实 exam.2) It is + adj. +从句从句It’s certain that… 肯定肯定… It is possible that... 很可能很可能…… It is unlikely that... 不可能不可能…… It is obvious that… 很明显很明显… It is necessary \important \natural\... that… +(should) +do… It is possible that 很可能)she will come *_________________(很可能很可能 back tomorrow.

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。
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。
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。
依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/不行以省。
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/不行以省。
留意: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 matter 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,担当确定成分.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。
主语从句讲解及其练习主语从句是一个句子,用作句子的主语。
主语从句有三种连词类型。
第一种是从属连词引导的主语从句,包括that、whether和if。
其中,that引导主语从句时,that本身没有意义,不做成分,不能省略。
例如:It seems unlikely that you will win the medal。
主语从句通常用it作形式主语。
而whether引导主语从句时,whether本身有意义(表示“是否”),不能省略。
注意,不能用if引导主语从句,只能用whether。
例如:Whether we will hold a party in the open air tomorrow depends on the ___.第二种是由连接代词引导的主语从句,包括who、whose、whom、which、what、___、whomever、whichever和whatever。
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 ___ we do is to serve the people。
注意,whatever和whoever在主语从句中不含疑问意义,可以在从句中作主语、宾语、表语等。
例如:Whoever breaks the law should be punished。
Whoever breaks the law。
he should be punished.最后,要注意主语从句的格式和语法正确,避免明显的段落错误。
三、形式主语it的使用有时为了句子的平衡,我们会在主语从句处使用形式主语it,将真正的主语从句放到句末。
这种情况分为四种情况: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,形式为It is + 名词 + 从句。
例如:It is a fact that…(事实是……)It is good news that…(是好消息)___…(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。
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。
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……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……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。
