表语从句讲解

一．定义：

表语从句就是用一个句子作为表语。位于系动词之后，说明主语身份，特征，属性或状态。比较：

The problem is puzzling.

主语连系动词形容词作表语

The problem is when we can get a pay rise.

主语连系动词一个句子作表语---表语从句

二、系动词的分类（了解哪些词为系动词）

系动词有表示状态的；有表示状态变化的。

表示状态的有：

1）be, seem ,appear 等。

2）look ,sound ,feel ,taste ,smell 等，由感官动词变化而来。意思为“看（听、摸、尝、闻）起来”。

Mr. Li looks quite young. 李先生看起来很年轻。

3）stand ,keep ,prove ,remain 等由不及物动词转化而来。

The machine has been standing idle. 这台机器一直闲着不用。

2.表示状态变化的：

become ,get ,grow, fall, turn等

He has fallen ill. 他已经病倒了。

三连接表语从句与主句的关系词主要有三类：

1. 从属连词：that（无有词义）, whether（是否,if （是否）

2. 关系代词：who（谁，主格）, whom（谁，宾格）,whose谁的，所有格）, what（什么）,which（哪个，哪些）

3. 关系副词：when（什么时候）where（什么地方）why（为什么）, how（怎样）例如：

The fact is that we have lost the game. 事实是我们已经输了这场比赛。

That’s just what I want. 这正是我想要的。

This is where our problem lies. 这就是我们的问题所在。

That is why he didn’t come to the meeting.那就是他为什么不到会的原因。

It looks as if it is going to rain. 看上去天要下雨了。

It is because you eat too much那是因为你吃得太多了。

The reason why he was late was that he missed the train by one minute this morning

（当主语是reason时，表语从句要用that引导而不是because）

另外，与其他名词从句有所不同的是as, as if/though, because也可用来引导表语从句.如：

He looked just as he had looked ten years before.他看起来还与十年前一样。

She seems as if she had done a great thing.她看起来好像做了一件大事。

It is because you eat too much.那是因为你吃得太多了。

【注意】because可引导表语从句，但与之同义的since, as, for等也不用于引导表语从句。

四注意事项（重点看）

1. 表语从句要用陈述语序。如：

That is where the famous scientist was born.

This is why she is so happy today

2. that和what在引导的表语从句

That本身没有词义，在句中只起连接作用，不充当句子成分；

what则表示“所……的（人或事）”，在表语从句中充当主语或宾等。

如：

That fact is that more than seventy percent of the earth’s surface is covered by water.

What he told you was what had been discussed at the meeting.

3. If 与whether

均意为“是否”引导表语从句时，只能用whether, 不能用if。如：

The question is whether we can finish our work by tomorrow evening.

4 语气

1）主语为advice, order, idea, notion, proposal, suggestion, request等一些表示“建议、劝说、命令”的名词，之后的表语从句中，谓语动词用虚拟语气。should+动词原形表示，should 可省略。如：

My suggestion is that we (should) start early tomorrow. 我的建议是我们明天一早就出发。

Our only request is that this should be settled as soon as possible.

我们唯一的请求就是尽快解决这个问题。

2）As if/though引导的表语从句时，从句谓语多用虚拟语气。

这是因为从句中的情况与事实不相符。

具体来说，如果从句表示与现在事实相反，谓语动词用一般过去式；

如果从句表示与过去事实相反时，谓语动词“had+done”，

如果从句表示将来的可能性不大，用would(might ,could )+动词原形，如： Li Lei is now in a new jacket he looks as if he were an American boy.

The girl is giving us a vivid description of moon. It seems as if she had been to the moon many times.

但是，如果as if ,as though 引导的表语从句所表示的与事实相符，从句则用陈述语气，如：The clouds are gathering. It looks as if is going to rain.

5 时态

不像宾语从句，在有表语从句的复合句中，主句时态和从句时态可以不一致。

The question is who will travel with me to Beijing tomorrow.

The question is why he cried yesterday.

6 记住两个句型

A．The reason is that…B．That is why （because）…

例如：

The reason is that he didn't catch the bus.理由是他没有赶上公共汽车。

That is why he came late.那就是他晚的原因。

That is because he didn't catch the bus.那是因为他没有赶上公共汽车。

名词性从句 在复合句中起名词作用的从句叫做名词性从句。名词性从句的作用相当于名词,因此主语从句、表语从句、宾语从句和同位语从句分别作主句的主语、表语、宾语和同位语。主语从句:Who will win the match is still unknown. 宾语从句:I want to know what he has told you. 表语从句:The fact is that we have lost the game. 同位语从句:The news that we won the game is exciting. 引导名词性从句的连接词可分为三类: 连接词(不充当从句的任何成分: 连接代词:what, who, whom, whose, which, wh+ever 连接副词:when ,where ,how ,why Object Clauses 宾语从句 一、宾语从句的概念:宾语从句在复合句中作主句的宾语。 位置:通常放在主句谓语动词(及物动词或介词之后。 句子结构:主句+连词(引导词+ 宾语从句 e.g. She asked if these answers were right. We can learn what we do not know. He will talk to us about what he saw in the U.S.A. I don’t know where we will hold the meeting. 通过观察,我们可以知道宾语从句的语序用陈述语序: 连接词+主语+谓语+其他成分 1Could you tell me______.

(完整)高中英语语法解析---名词性从句

高中英语语法解析---名词性从句 在句子中起名词作用的句子叫名词性从句(Noun Clauses）。名词性从句的功能相当于名 词词组, 它在复合句中能担任主语、宾语、表语、同位语、介词宾语等，因此根据它在句中 不同的语法功能，名词从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。 一．主语从句 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。 1. 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，主语从句的连接词没有变化。而 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。被强调部分指人时也可用who/whom。例如： a) It is a pity that you didn’t go to see the film. 你不去看那场电影真可惜。 b) It doesn’t interest me whether you succeed or not.我对你成功与否不感兴趣。 c) It is in the morning that the murder took place.谋杀案是在早上发生的。（强调句型） d) It is John that broke the window.是John打碎的窗户。（强调句型） 2. 用it 作形式主语的结构 (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 appears that…似乎… (4) It ＋过去分词＋从句 It is reported that…据报道… It has been proved that…已证实… It is said that…据说… 3. 主语从句不可位于句首的五种情况： （1）if 引导的主语从句不可居于复合句句首。 （2）It is said /reported…结构中的主语从句不可提前。例如： 正确表达：It is said that President Jiang will visit our school next week. 错误表达：That President Jiang will visit our school next week is said. （3）It happens/occurs…结构中的主语从句不可提前。例如： 正确表达：It occurred to him that he failed in the examination. 错误表达：That he failed in the examination occurred to him. （4）It doesn’t matter how/whether …结构中的主语从句不可提前。例如： 正确表达：It doesn’t matter whether he is wrong or not. 错误表达：Whether he is wrong or not doesn’t matter.

表语从句讲解及专项练习 概念：表语从句是在复合句中作表语的名词性从句。 放在系动词之后,一般结构是“主语+系动词+表语从句” 可以接表语从句的连系动词有be, look, remain, seem等。 ★ The trouble is that we are short of money.困难是我们资金短缺。 ★ That is why stone walls are used instead of fences around New England fields.这就是为什么在新英格兰用石头墙而不用栅栏的原因。 ★ At that time, it seemed as if I couldn't think of the right word anyhow.当时,我似乎怎么也想不出一个恰当的字眼来。 引导表语从句的词： 从属连词that、whether、as though、 as if（That引导表语从句时，在口语中，间或可以省略。） 关系代词who, what, which, whom, whose, whatever, whoever, whomever, whichever等； 关系副词when, where, why, how, however, whenever, wherever等。 ※由从属连词that，whether引导的表语从句。 that在引导表语从句时无词义，而whether有词义，意为、“是否”。这时主句的主语常常是些抽象名词，如question(问题)，trouble(麻烦)，problem(问题)，result(结果)，chance(可能性)，suggestion(建议)，idea(想法)，reason(理由)等。表语从句对主句主语进行说明、解释，使主语的内容具体化。 例如： ★ The trouble is (that) she has lost his money. 麻烦的事是他丢了钱。 ★ The question is whether we need more ice cream.问题是我们是否还需要一些冰淇淋。 ★ The problem was that it was too valuable for everyday use.问题是它作为日常之用太贵重了。 ★ What she couldn’t understand was that fewer and fewer students showed interest in her lessons. 我们不能理解越来越少的学生对他的课不感兴趣。 ※由关系代词引导的表语从句。 关系代词who, what, which, whom, whose, whatever, whoever, whomever, whichever等引导表语从句，在句中作主语、宾语、表语，关系代词不能省略。 例如： ★ The question is which of us should go.问题是我们哪一个应该去。 ★ The problem was who could do the work.问题是谁能做这项工作。 ★ That's what he is worrying about.那就是他在担心的事。 ★ That's what we should do.那是我们应该做的。 ※由关系副词引导的表语从句。 关系副词 when, where, how, why 除在句子起连接作用外，在从句中还充当时间，地点，方式或原因状语，本身 具有词义。 例如： ★Go and get your coat. It's where you left it. 去把雨衣拿来。就在你原来放的地方。
