英语教案---主语从句

主语从句：做主语用的名词性从句，因其在复合句中做主语，又称主语从句，引导主语从句的有连词that，whether，连接代词who，what，which，连接副词when，where，how，why等。

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）例如：That you will win the medal seems unlikely.That she survived the accident is a miracle.It is a miracle that she survived.that引导的主语从句:引导词that_____ 含义，在句中_________成分__________省。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.It doesn’t matter too much whether she is coming or not.whether 引导的主语从句: whether有含义，意为_________在句中_____成分_____省。注意：引导主语从句，不能用if不能在开头，只能用whether。

对于以连词thatwhether引导的主语从句，可以用形式主语______替代主语从句,避免头重脚轻。

（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，________(做/不做)成分.例如：What you need is more practice.Whatever we do is none of my busine.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_____含义,在句中作_____ 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： 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；类似的名词还有：a pity；a wonder；a good thing；a surprise等。It is a mystery to me how it all happened.It is no surprise that Bob should have won the game.It is +形容词+从句

It is neceary 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„„

类似的形容词还有：strange;natural;obvious;true;good;wonderful;poible;unlikely;quite;unusual;certain;evident;worth-while;surprising;interesting;astonishing, etc.It seems obvious that we can not go on like this.It is neceary that you（should）master the computer.注：有些主语从句中，谓语动词很多为“（should）＋动词原形”，即要用虚拟语气。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„„

类似的过去分词还有：known;estimated;expected;believed;thought;hoped;noted;discued;required;decided;suggested;demanded;made clear;found out,etc.例如：It is reported that the weather will become warmer and warmer.It has not been made clear when the new road is to be opened to traffic.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 mied my train.It happened that I saw him yesterday.(2)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。(3)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

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)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______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________省略 主语从句练习
