表语从句

1、概述

用作表语的从句叫作表语从句，它位于主句中的连系动词之后。

引导表语从句的词有从属连词that、whether、as though(if)；

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。

可以接表语从句的连系动词由be, look, remain, seem等。

The trouble is that we are short of money.

That is why stone walls are used instead of fences around New England fields.

At that time, it seemed as if I couldn't think of the right word anyhow.

2、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。

5、由连词because，as if/as though等引导的表语从句

主语从句、表语从句、宾语从句、同位语从句，在整个句子中所起的作用，相当于一个名词因此，这四种从句通称为名词性从句。引导名词性从句的连接词可分为三类：连接词that，whether, if （不充当从句的任何成分）连接代词：what, whatever, who, whoever, whom, whose, which,连接副词：when, where, how, why, wh- ever 名词性从句连接词的选用 一、that 和what的选用： that 和what都可引导所有的名词从句。但是，what除起连接作用外，还在名词性从句中充当成分，可做从句的主语、宾语、或表语。而that在名词性从句中不充当任何成分，只起连接作用。 二、if 和whether 的选用 不能使用if 的情况： a. 主语从句句首 b. 表语从句，同位语从句 c. if引起歧义 d. 介词后的宾语从句 e. 与to do连用 f .whether or not 连在一起引导宾语从句时不用if 三、其它连接代词和副词的连用 主要根据名词性从句中的具体意义,正确的选择who、which、when、where、why、how 等连接词，这些连接词既具有疑问含义，又起连接作用，同时在从句中充当各种成分。 四、引导词that 的省略 that 可省略的情况：单个宾语从句中的that可省略 that不可省略的情况：a.主语从句b.表语从句c.同位语从句d.用it做形式宾语的宾语从句e.并列的宾语从句中，后几个从句的引导词that 不能省略 五、同位语从句的引导和辨别 1.同位语从句的格式：n.+ 连接词+ 从句 2.能接同位语从句的名词有：fact、idea, news, information, order, belief, suggestion, advice等. 3.连接词通常是that,也可根据含义选用whether, what, when, where 等来引导同位语从句. 4.中心词是“意见、建议、命令”从句要用虚拟（should）do 六、同位语从句和定语从句的区别 1.定语从句是先行词的修饰语。从句中that充当成分，做宾语时可省略。 2.同位语从句表明中心词的具体内容。that 在同位语从句中不做任何成分,只起连接作用,无具体含义,且不可省略. 判断从句类型 七、宾语从句的时态呼应 1. 如果主句时态是现在时或将来时,从句谓语可根据句意需要而选用任一种时态. 2. 如果主句时态是过去式，从句要改成相应的过去式 八、it做形式主语 常用句型如下：（1）It + be + 名词+ that从句（2）It + be + 形容词+ that从句 （3）It + be + 动词的过去分词+ that从句（4）It + 不及物动词+ that 从句

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。

(完整word版)高中英语名词性从句讲解

名词性从句讲解 在复合句中起名词作用的从句叫做名词性从句。它包括主语从句、宾语从句、表语从句和同位语从句。名词性从句是中学阶段的一个重要语法项目，在历年的高考中几乎都涉及到，并且每年的命题各有变化。分析历届高考试题名词性从句考查的焦点主要有以下六个方面 1. 考查名词性从句的语序问题 2. 考查引导词that与what的区别 3. 考查it在名词性从句中作形式主语或形式宾语的用法 4. 考查whether与if的区别 5. 考查名词性从句中的疑问词+ever引导的名词性从句与no matter+疑问词引导的状语从句的区别 6. 考查名词性从句的虚拟语气问题 语法要点剖析 一、名词性从句 主语从句、表语从句、宾语从句、同位语从句，在整个句子中所起的作用，相当于一个名词。因此，这四种从句通称为名词性从句。 引导名词性从句的连接词可分为三类： 连接词：that, whether, if （不充当从句的任何成分） 连接代词：what, whatever, who, whoever, whom, whose, which. 连接副词：when, where, how, why 1. 主语从句 作句子主语的从句叫主语从句。主语从句通常由从属连词that，whether，if和连接代词what，who，which，whatever，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；连接代词和连接副词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。例如： What he wants to tell us is not clear. 他要跟我们说什么，还不清楚。 It is known to us how he became a writer. 我们都知道他是如何成为一名作家的。 Where the English evening will be held has not yet been announced. 英语晚会将在哪里举行，还没有宣布。 有时为避免句子头重脚轻，常用形式主语it代替主语从句作形式主语放于句首，而把主语从句置于句末。主语从句后的谓语动词一般用单数形式。常用句型如下： （1）It + be + 名词 + that从句（2）It + be + 形容词 + that从句 （3）It + be + 动词的过去分词 + that从句（4）It + 不及物动词 + that 从句另注意在主语从句中用来表示惊奇、不相信、惋惜、理应如此等语气时，谓语动词要用虚拟语气“(should) +do”，常用的句型有： It is necessary (important, natural, strange, etc.) that … It is a pity (a shame, no wonder, etc.) that… It is suggested (requested, propose d, desired, etc.) that… 2. 宾语从句 名词句用作宾语的从句叫宾语从句。引导宾语从句的关联词与引导主语从句表语从句的关联词大致一样，在句中可以作谓语动词或介词及非谓语动词的宾语。 1. 由连接词that引导的宾语从句 由连接词that引导宾语从句时，that在句中不担任任何成分，在口语或非正式的文体中常被省去，但如从句是并列句时,第二个分句前的that不可省。例如： He has told me that he will go to Shanghai tomorrow. 他已经告诉我他明天要去上海。 We must never think (that) we are good in everything while others are good in nothing. 我们决不能认为自己什么都好，别人什么都不好。 注意：在demand、order、suggest、decide、insist, desire, demand, request, command等表示要求、命令、建议、决定等意义的动词后，宾语从句常用“（should）+ 动词原形”。例如： I insist that she (should) do her work alone. 我坚持要她自己工作。
