?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，whichwhatever，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。
What I want to know is this. 我想知道的就是这一点。
(4)如果句子是疑问句，则必须用带形式主语it的结构：
如：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？
3、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则可以省略：如：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) 主语从句应注意的几个问题：
1、that引导的主语从句既可放在句首，也可放在句尾，但在下列情况下that从句不可提
前。
（1）在It is said/reported...that结构中：
如：It is reported that a bank was robbed yesterday.
（2）在Ithappened/occurred...结构中：Ithappenedthattheteacherwasnotintheofficethatday.
（3）含主语从句的复合句是疑问句时：
如：Is it ture that you will give up the job?
2、下面这种情况常用it作形式主语。在It doesn't matter+what/whatever…结构中。如：It doesn't matter what you say.
3、由what引导的主语从句谓语动词单复数问题what引导的主语从句一般按单数对待，但是，在实际使用中究竟按单数还是按复数对取决于其成分的含义。
如：What we need is more time.
What were left behind were five empty bottles.

考研英语主语从句翻译方法 一、关联词或从属连词位于句首的从句+主句谓语+其他成分 它们一般是译在句首，作为主从复合句的主语。这样的词有关联词what, which, how, why, where, who, whatever, whoever, whenever, wherever及从属连词that, whether, if.如：What we now will describe is how the magnetic nature of iron oxide can uniquely be exploited as a separation process utilizing a magnetic filtration system. 参考译文：现在我们所要介绍的是如何奇特地利用氧化铁的磁性而提出一种使用磁力过滤系统的分离法。 分析：其中关联词可译为：...所。 二、it+谓语+that(whether)引导的从句 如果先译主句，可以顺译为无人称句。有时也可先译从句，再译主句。如果先译从句，便可以在主句前加译"这"。如： It can be seen that precleaning alone would not reduce the total sulfur content of the four coals to levels anywhere near the standards. 参考译文：可以看出，这四种煤的总含硫量仅靠预先洗选将不能降低到完全接近标准规定的水平。 It is a matter of common experience that bodies are lighter in water than they are in air. 分析：有时为了使译文成分完整，可以补充上泛指的主语（如人们...、大家...）。 参考译文：物体在水中比在空气中轻，这是一种大家共有的经验。类似的结构还有：it is (universally) known that...大家都知道...it is believed that...人们都相信...
主语从句( if除外) 一定义：在复合句中充当主语的句子，叫主语从句；位于句首。 二：读例句，理解句意，思考，分析，总结。 1：连接词that 引导的主语从句： EG:1）That you are so angry bothers me. 你如此生气使我很烦恼。 2）That she survived the accident is a miracle.她在事故中幸免于难简直是奇迹。 3）It was a pity (that) you didn’t go to the talk.很遗憾你没有去听报告。 4）That he has moved to New York is not true.= It is not true that he has moved to New York. 5）That the earth is round is true.= It is true that the earth is round. 总结：在连接词that 引导的主语从句中，that ___含义，在句子___做成分，__省。EX: 1)______ he will succeed is certain. 2) ________ you didn’t go to the park was a pity. 3) ______ you will win the medal seems unlikely. 2: 连接词whether引导的主语从句。 EG: 1）Whether wild life can be well protected is of great importance. 2）Whether Mary really heard him is really doubtful. 3）Whether it will do us harm remains to be seen. 是否对我们有害还要看一看。 4）Whether he will come hasn’t been decided.= It hasn’t been decided whether he will come. 总结：在连接词whether 引导的主语从句中，whether__含义，____做成分，__ 省。EX: 1) ______ she is coming or not doesn’t matter too much. 她来不来都无关紧要。 2) ______ they would support us was a problem. 他们是否会支持我们还是一个问题。 3) _______ to hold the meeting has not been discussed. 3：在连接代词（who,whom,whose,which,what,whoever,whomever,whichever,whatever）引导的主语从句中。 EG: 1）What is needed for the space trip is careful preparation. 2）Who will be sent to carry out the task has been settled. 3）Whom she borrowed money from still puzzled me. 4）Which side will win is not clear. 5）What I want to know is this. 6）Whoever breaks the law will be punished.( _____ 从句) = Anyone who breaks the law will be punished . ( _____ 从句) 比较：Whoever breaks the law , he should be punished. ( _____ 从句) = No matter who breaks the law, he should be punished. ( _____ 从句) 总结：在连接代词引导的主语从句中，连接代词__含义，___成分，做___语、___语、___语，_____ 省。
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
It + be + adj.+ that... 主语从句中常见的一种形式，即以引导词that引出的主语从句，常以形式主语it 代替。主语从句的时态不受主句的时态影响和限制，根据句子意思用适当的时态。结构：It is+adj.+that从句。常用于这个句型的形容词有：necessary, important, clear, strange, true, good, wonderful, possible, unusual, certain, surprising; interesting等。 根据汉语意思完成句子。 1．他可能已经把一切都告诉她了。 ____ is possible that he ____ ____ her everything. 2．海怪突然出现了很奇怪。 It ____ _____ that sea monsters suddenly ___________. 3．毫无疑问她将会在测验中做得很好。 It is certain _____ she ____ ____ well in her exam. 用适当的形容词填空 1. Miss Li often says that it is ________ to learn a foreign language well. 2. Look at the black clouds in the sky. It is ________ to rain soon. 3. It is ________ that Sunday is the first day of the week. 4. Isn’t it ________ that chickens can swim? 5. Is it ________ the lazy boy can catch up with all his classmates? 很多形容词可以与介词连用。我们已学过很多这样的搭配，现在一起来复习一下。形容词与某个特定的介词连用，表示某个特定的意思。 ①与about连接的形容词：be worried about“担心……”；be excited about“对……感到兴奋”；be careful about“小心、谨慎”；be mad about“狂热地迷恋”；be anxious about “为……感到焦虑”；feel nervous about/ at“对……感到心神不安”。 ②与at连接的形容词：be shocked at“对……感到震惊”；be good at“擅长……”；be bad at“在某方面不好或坏”；be angry at/ about sth“对……生气”；be mad at sb“对……发怒”；be surprised at“对……感到惊讶”。 ③与as连接的形容词：be famous/ known as“作为……而著名”；be known as “被叫作……”。 ④与for 连接的形容词：be good for“对……有好处”；be bad for“对……有害”；be afraid for“为……而担心”；be famous / known for sth“因……而著名”；be mad for “渴望”；be happy for“为……感到高兴”；be responsible for“负责，有责任”；be free for“对……免费”；be available for“有空的”；be thankful for“感谢，感激……”；be ready for“为……做准备”。 ⑤与from 连接的形容词：be different from“与……不同”。 ⑥与of 连接的形容词：be short of“缺乏……”；be afraid of“害怕……”；be unaware of “没意识到……，不知道……”；be tired of“厌倦，厌烦……”；be proud of“为……感到自豪”；be full of“充满……的”。 ⑦与on 连接的形容词：be based on“基于，根据”；be keen on“喜爱”；be dependent on “依靠”。
