主语从句详细讲解及综合练习
主语从句
一、概念：在复合句中起主语作用的从句叫主语从句。
(一) 连接词
从属连词：that、whether；
关系代词：who, what, which , whom, whose, whatever, whoever, whomever, whichever 关系畐【J词：when, where, how, why, however, whenever, whereve等；例: What he said is true.
That you don' t like him is none of my bus in ess. Whether the football game will be
played depe nds on the weather.
主语从句的时态：不受主句的时态影响和限制。
(1)______ he finished writing the composition in such a short time ______ 惊讶)us all.
(2)_______ ___________________________________ w e will go for an outing tomorrow (remains, remained) unknown.
(3)_______ _____________________ will be our monitor (be) decided yet.
(4)______ we must study for ______ (be) a question of great importanee.
(5)_______ _______________________ caused the accident (remains, remained) unknown.
(6)______ you did _______ (be)right.

小结：
(1)主语从句的时态：不受主句的时态影响和限制。
(2)连词位于句首不能省略(3)主语从句大多数情况下视为三单，但也有例外，如例9
1. 从属连词that, whether引导的主语从句。
从属连词that, whether在主语从句中的作用只是引导主语从句，在从句中不担任成分，不能省略。
例: ___________ they will go is certa in.
_________ s he will come or not is still a questi on. she's coming or not does n't matter
too much.
2. it作形式主语引导主语从句。
如果主语从句太长，为避免句子结构头重脚轻，我们可用it作形式主语，而把主语从句放
在主句谓语部分之后。That引导的主语从句可用it代替，that不可省略。
It ' s reported that … 据报道 ... It ' s decided that …尚未决定
It ' s believed that … 据认为 .. It ' s announced that …据宣布 ..
It suddenly struck me (occur to me that … 我突然想至U (感觉至U) .
(5)其他
It doesn' t matter …是无关紧要的
It makes no differe nee …毫无区另
It is of little con seque nee that-无关紧要 It is a pity __________ she has made such a mistake 她犯这样的错误是令人遗憾的事。
It's strange _________ he did n't come yesterday 他 昨天没来是很奇怪的。
It is reported _________ the nu mber of wild ani mals in Africa is decreas ing.
据报导非洲野生动物的数量正在减少。
It is said __________ there was a terrible pla ne crash this morning.
据说今天早上有一起可怕的飞机坠毁事故。
1主语从句在句首时，必须由连注意：
接词引导，不能省略这些连接词；但是如果用 it 做形式主语，而把主语从句放在句末时，从 属连词that 可以省略。
误：They should like each other is natural.
正： That they should like each other is n atural.
正: It is natural that they should like each other.
2)如果主语从句放在句首，不能用if 引导，但是如果用it 做形式主语，而把主语从句放在句 末时，也可以用if 引导.
误：If Mary really heard him is really doubtful.
正: It was doubtful if Mary really heard him.
4) .用于 It is important / natural / necessary / impossible that...句型中,主语从句应使用虚拟语 气谓语动词用 “should +动词原形”的形式,should 有时可以省略。
5) 在 It + be+suggested/advised/ordered/requestedn sisted/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。
Does ______ matter if he can't finish the job on time ?A. this B. that C. he D. it
______ is a fact that En glish is being accepted as an intern ati on al la nguage.
A. There
B. This
C. That
D. It
用作it 作形式主语的结构： (1) It is/was + 形容词 +that 从句 It ' s natural that … 很自然 .... It ' s fortunate that … 幸运的是 It ' s unlikely that …不可能 (2) It is/was + 名词 +that 从句 It ' s a pity that … 遗憾的是 .... It ' s good news that …是好消息… It ' s an honour that … 非常荣幸 It ' s com mon kno wledge that … 是常识… (3) It +不及物动词+that 从句 It seems that … 似乎 ... It appears that-?看来 ... (4) It is/was +过去分词+that 从句
It ' s obvious that …显而易见 It ' s (im)possible …(不)可能… It ' s stra nge that ??奇怪的是 ......
It ' s a fact that …事实是 ... It ' s a wonder that …不足为奇… It ' s a shame that--真是可It happe ned that …碰巧 It turns out that- ??结果…

A. masters
B. should master
C. mastered
D. will master
______ is known to everybody, the moon travels round the earth once every month.
A. It
B. As
C. That
D. What
3、由关系代词引导的主语从句。
(1)关系代词who, what, which, whom, whose, whatever, whoever, whomever, whicheve等，引导主语从句时，它们分别在从句中担任主语、宾语或定语，不能省略。
_________ leaves the room last ought to turn off the lights.走得最晚的应当关灯。
_________ you have done might do harm to other people. 你的行为可能伤害别人。
_________ he said at the meeti ng ast oni shed everybody prese nt.
他在会议上的发言时所有入会者吃惊。
_________ made the long dista nee call is not importa nt. 谁打的长途电话并不重要。
(2)what引导主语从句“的东西/事情”时，可用来表示the thing(s)which这种意思，引导从句，表示一样东西与一件事情，这种用法的what称为关系代词型what，who，whom，which，what可以和ever构成合成词，和what 一样引导从句，ever起强调作用。这些关系词在句子中充当成分，所以不能省略。此类主语从句不能用形式主语it引导。
_________ (二The thing which I n eed) is a mobile pho ne.
我所需要的是一部移动电话。
_________ leaves the office (=A ny one who leaves the office)should tell me.
无论是谁离开办公室都应该告诉我。
4、关系副词引导的主语从句。
连接畐词有when, where, why, how, however, whenever, whereve等引导主语从句时，它们在从
句中担任状语，不能省略。此类主语从句可以转换为以it作形式主语的句子。
_________ he did n't come here is not clear to anyone. 他为什么没来谁也不清楚。 a telepho ne works is a questi on which not every one can an swer.
电话是怎样工作的，这个问题并不是每个人都能回答。
_________ she has gone is not known yet. 她去了哪儿，还不知道。they will start has not bee n decided yet. 他们何时动身还未定下来。
_________ he did it did n't c on cern me. 他为什么做这件事与我无关。
5、主语从句不可位于句首的四种情况。
(1) 含主语从句的复合句是疑问句、感叹句时，主语从句不可提前，用引导词it作形式主语。Is it really true that he has gone abroad? 他真的出国了吗？
How surprisi ng it was that he failed in the exam! 真令人惊奇，他考试没有及格！
(2) It is said, reported,…结构中的主语从句不可提前。
It' s said that the play is very interesting. 据说戏剧很有趣。It' s reported that the highway will be opened to traffic next week. 据报道，高速路下周通车。
(3) It happens, occurs…结构中的主语从句不可提前。
It occurred to her that she had forgotten to lock the door. 她突然想起忘了锁门。
It happe ned that I met him in the street. 我恰巧在大街上遇到了他。
(4) It doesn' t matter how, whether or no…结构中的主语从句不可提前。
It doesn' t matter whether he likes it or n ot. 他喜欢与否无关紧要。
It does n' t matter how he will come. 他怎么来不重要。
6、it作形式主语与it引导强调句的比较。
it作形式主语代替主语从句，主要是为了平衡句子结构(特别是谓语较短时) ，主语从句
的连词没有变化。而it引导强调句则是对某一句子成分的强调(这一成分可以是词、词组或句子)，其结构是“ It is(was)+强调成分+thaf'。无论强调什么成分，都要求用连接词that(强
调人时可以用who代替)。
It is certai n that she will succeed她会成功是肯定的。(主语从句) It is in New York that I met him.是在纽约我见到了他。(强调句)
7、what与that在引导主语从句时的区别
what弓I导主语从句时在句时在从句中充当句子成分，如主语?宾语?表语，而that则
不然。例如：
1) What you said yesterday is right.
2) That she is still alive is a con solati on.
That只起连接作用，不做成分
1. ______ you have done might do harm to other people. A. That B. What C. Whether D. How
2. __ he said at the meeti ng ast oni shed everybody prese nt.
A. What
B. That
C. The fact
D. The matter
3. _ we can't get seems better tha n __ we have.
A. What; what
B. What; that
C. That; that
D. That; what
4. It worried her a bit ______ her hair was tur ning grey. A. while B. that C. if D. for
5. ______ you don't like him is none of my bus in ess .A. What B. Who C. That D. Whether 8. 主语从句需注意的问题
(1) 主语从句中用陈述语序
What she is afraid of is their tak ing her to Paris. ( What is she afraid of… Wrong )
(2) 主语从句后谓语动词用第三人称单数
That they haven t phoned is strange.
(3) that引导的主语从句中，that不可被省略
That price will go up is certa in.
⑷引导主语从句，放在句首时，不能用if，只能用whether o
Whether we will hold a party in the ope n air tomorrow depe nds on the weather.
_______ t he 2000 Olympic Games will be held in Beiji ng is not known yet.
A. Whe never
B. If
C. Whether
D. That
______ w e'll go camping tomorrow depends on the weather. A. If B. Whether C. That D. Where (5) 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 wha 要注意和whatever, whoever弓丨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 puni shed.)
Whoever breaks the law, he should be punished.(让步状语从句)
( =No matter who breaks the law, he should be puni shed) anyone与the person皆不能引导从句.
__ l eaves the room last ought to turn off the lights.A. Anyone B. The pers on C. Whoever D. Who It is gen erally con sidered un wise to get a child _____ he or she wan ts.
A. however
B. whatever

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

名词性从句用法详解
名词性从句用法详解 一、概说名词性从句，即指性质相当于名词的从句，它包括主语从句、宾语从句、表语从句和同位语从句。从高考的考查的实际情况来看，名词性从句考得最多的是宾语从句，其次是主语从句，再次是表语从句，而同位语从句则很少考查。 二、名词性从句的一般引导词 1. 连接词 that 只起连接作用，没有任何意思，也不充当句子成分，在宾语从句中可省略，但引导其他名词性从句时通常不省略。如： I hope (that) you enjoy your holiday. 希望你假期过得好。（宾语从句可省） That he likes you is very obvious. 很显然他喜欢你。（That引导主语从句不能省） 2. 连接词 whether 也不充当句子成分，但有自己的意思，表示“是否”；引导宾语从句时，可换成 if，但引导其他名词性从句时不能换成 if。 He asked whether [if] I would show him the way. 他问我是否可以给他带路。 Whether it will do us harm remains to be seen. 是否对我们有害还要看一看。(引导主语从句，不能用 if 代替 whether) 3.连接代词 who(m), whose, which, what 等，均有各自的意义，在从句中作主语、宾语、定语等。如： That’s why she wanted to leave. 这就是她想离开的原因。 When we arrive doesn't matter. 什么时候到没有关系。 Tell me which one you like best. 告诉我你最喜欢哪一个。 4.连接副词 when, where, why, how 等，也各自有自己的意义，在从句中作状语。如： The question is how we should carry out the plan. 问题是怎样执行这个计划。 When she’ll be back depends much on the weather. 她什么时候回来在很大程度上要看天气。 Why he did it will remain a puzzle forever. 他为什么这样做将永远是一个谜。 三、名词性从句的重要引导词 1. what 用于引导名词性从句是一个十分重要的引导词，它可引导主语从句、宾语从句和表语从句，但不用于引导同位语从句。它引导的名词性从句有两个意思是：一是表示“什么”，带有疑问意味；二是表示“…所…的”，相当于一个先行词后接一个关系代词。 如： I don’t know what you want. 我不知道你想要什么。 I don’t know what you want is this. 我不知道你所想要的是这个。 2. whoever, whatever, whichever 等也可引导名词性从句，其意分别为“所…的一切事或东西”、“任何…的人”、““…的任可人或物”等。如： Whoever wants the book may have it. 任何人要这书都可拿去。 I’ll do whatever I can to help him. 我们将尽我们所能来挽救他。 注意以下受汉语意思影响而弄错的句子： 任何人来都欢迎。 误：Who comes will be welcome. / Anyone comes will be welcome. 正：Whoever comes will be welcome. / Anyone who comes will be welcome. 另外，它们也可引导让步状语从句，其意为“无论…”、“不管…”，其意相当于no matter who [what, which]。如： Whatever happens, you must be calm. 不管发生什么情况，你都必须镇静。(whatever = no matter what)
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。
各类从句讲解与例句
英语中六大从句用法总结 1.主语从句 1）主语从句可直接位于主语的位置，如果从句较长，谓语又较短，可用it作形式主语，而将从句放在句末。常见的句型有： *It is a fact\a pity\a question\good news that... *It seems\appears\happened\has turned out that... *It is clear\important\likely\possible that... *It is said\reported\estimated\has been proved that...

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.

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
