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。
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
主语从句可以按其引导词的不同分为三类： 第一类,用从属连词that引导的主语从句,例如：That we shall be late is certain. That the driver could not control his car was obvious. 这种结构主要是对that从句的内容进行强调,属正式文体,连词that不可以省略；但是在一般情况下,往往使用先行it结构,即用it作形式主语,而把that从句放到后面,这时,在口语中,连词that 有时则可以省略.所以上述两句可以改为： It is certain that we shall be late. It was obvious that the driver could not control his car. 如果整个句子是疑问形式,就只能用先行it结构,例如： Is it true that he would take the risk?
Is it possible that they will come tomorrow? 常使用先行it结构,用that从句作主语的句子有下列几个句型： 1、It + be + 形容词+ that从句： It is clear that he was telling the truth. It’s probable that we’ll be a little late. 2、It + be + 名词词组+ that从句： It’s a pity that you can’t go with us. 3、It + 及物动词+ 宾语+ that从句： It worried her a bit that her hair was turning grey. It shocked me that Peter didn’t tell anybody where he was. 4、It + be + 过去分词+ that从句： It is said that he has been there many times. 5、It + seem/happen/appear等不及物动词+
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.

I don’t know what you need? 4. 连接副词引导 When we arrive doesn’t matter. 什么时候到没有关系。 When do we arrive? How it was done was a mystery. 这是怎样做的是一个谜。 How was it done? How this happened is not clear to anyone. 这件事怎样发生的，谁也不清楚。 How did this happen? How many people we are to invite is still a question. 邀请多少人还是一个问题。How many people are we to invite?
