主语从句
宾语从句
表语从句
同位语从句
在复合句中做主语的从句叫做主语从句。主语从句一般位于句首。
他要来参加会议使我们很兴奋。
That he will come to attend the meeting
tomorrow makes us excited.
主语
谓语
概念
1. 我们所需要的是水。
2. 我们所需要的是有用的书。
What we need is water.
What we need are useful books.
一: 主语为从句时, 谓语动词一般用单数形式; 但如果what引导的从句做主语代表复数概念(常可以从表语上看出) 时, 谓语动词则常用复数形式。
二: 主语从句的引导词
连词: that, whether, 连接代词who, which, what, whatever, whoever, 连接副词where, how, when, why, wherever等。由连接代词或连接副词引导的主语从句:它们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。从属连词that在主语中不做任何成分,只起引导从句的作用。
三: 形式主语it代替主语从句
主语从句在句中作主语, 主语从句可以位于句首, 但常见的主语从句多放在句末, 句首则用形式主语it。
e.g. That the earth is round is true.
= It is true that the earth is round.
1 It’s strange that I’m leaving school so
soon.
2 It’s useful that we learn how to write
articles for a newspaper.
3 It’s clear why the right training can help
you become a peer mediator.
4 It was unclear what they saw on the beach.
Underline the subject clauses in these sentences.

It作形式主语和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, 主语从句的连接词有变化。
It引导的强调句则是对句子某一部分进行强调, 无论强调的是什么成分, 都可用连词that。被强调部分指人是也可用who/whom。
e.g.
It is a pity that you didn’t go to see the film.
It doesn’t interest me whether you succeed or not.
It is in the morning that the murder took place.
It is John that broke the window.

主语从句
主语从句
在复合句中用作表语的从句是表语从句, 引导表语从句的关联词与引导主语从句的关联词大致一样, 表语从句位于连系动词am, is, are, was, were, seem, look, taste, remain后。
基本结构为:主语 +系动词 + that从句。
e.g. That’s what we should do.
That’s why I want to see you.
引导表语从句的词有:
连词: that, whether, 连接代词: what,
who, which, 连接副词:when, where, how, why,等。除此之外,还可由as if , as though, 或because 引导。that有时可以省略。
1. 在表语从句中, 当reason做主语时, 引导词只能用that, 不能用because。
e.g. 他迟到的原因是因为他没有赶上早
班车。
The reason why he was late was that
he didn’t catch the early bus.
2. Where, why, because, how等引导的从句作this is 和that is 的表语时, 表示具体的地点, 原因, 方式等。
e.g. This is why we put off the meeting.
3. 主语是 idea,??suggestion,?request,advice, order,等名词时, 作表语从句的动词为原形动词或should+原形动词。
e.g. My?suggestion?is?that?we (should) go
and help?him.
