高中英语表语从句详解

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。That引导表语从句时，在口语中，间或可以省略。

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。

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。

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。

3、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。

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。

4、由关系副词引导的表语从句。

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。

I had neither a raincoat nor an umbrella. That’s why I got wet through. 我们既没伞也没雨衣，这是我们淋湿的原因。

That is how mice ruin many stores of grain every year.那就是老鼠是怎样每年损害大量粮食的。

That is what he is worried about.那就是他所担心的。

5、由连词because，as if/as though等引导的表语从句。

It looked as if it was going to snow.看起来好像要下雪了。

That's because we never thought of it.这是因为我们从未想过此事。It seems as if he di dn’t know the answer.好像他不知道答案。

高中英语【语法归纳】宾语从句

宾语从句 1、定义如果一个句子在复合句中充当一个宾语，那么这个句子就是宾语从句。 2、与简单句的区分例：*I love teaching.---简单句 *I love what he is doing.---宾语从句 ★宾语从句在句中作及物动词或介词的宾语。例：*We can learn what we did not know. *I don't agree with what you said at the meeting. 3、语序宾语从句的语序一般都为陈述句语序。 A.一般情况下，即使是有疑问词，从句仍然是陈述句式。例：This book will show you what the best CEOs know. 这本书会告诉你最棒的总经理知道什么。 Can you figure out what the poet really means in this poem. 你能理解诗人在这首诗里真正想表达的是什么吗？ B.但个别宾语从句本应用陈述语序，可由于习惯而保持原疑问语序不变。例：I don't know what is the matter with him. I have no idea what was the matter with him. 我不知到他到底怎么了。关于matter的从句都是疑问语序基本上说I don't know what is wrong也是

对的，可一般来说都是分成两句讲。 I don't know.Is anything wrong？/what's wrong with you. C.特殊类型的宾语从句：当主句中的谓语动词表示认为、建议、猜测时，如think,say,guess,suppose,suggest,say,believe,feel,consider等，这时宾语从句的引导词是who,which,what,when,where,how,why,就不能按照正常语序安排,经常会将这类词放在句首。例：What course do you say I should take up this semester? Who do you think the public might choose as their favorite singer this year? 4、连接词（引导词） 1）陈述句做宾语（包括肯定句和否定句），连词由that引导。在口语或非正式体中常省略。例：I don’t know（that）Tom was late again. 2）一般疑问句做宾语，用if／whether引导，if或whether在宾语从句中不作成分。但if和whether在句中的意思是“是否”。例：I want to know if(whether)he lives there. He asked me whether(if)I could help him. ★if/whether的区别 A.从句放在句首表示强调时，只能用whether； B.及物动词discuss后的宾从，只用whether； C.if与whether都可以与or not连用，但后面紧跟着or not时只能用whether； D.介词后的宾从只用whether; E.后接动词不定式时用whether. 3）特殊疑问句做宾语，用特殊疑问词连接（宾语从句缺什么成分就选择相应的特殊疑问词）。

高中英语语法系列：定语从句

高中英语语法系列：定语从句知识要点 1.关系代词和关系副词的选用 2.限制性定语从句和非限制性定语从句的区别 3.几组的关系词特殊用法一、定义：在复合句中，修饰名词或代词的从句叫做定语从句。 The happy man who lives next to me sells vegetables. You must do everything that I do. 被定语从句修饰的词，叫先行词。比如上面两句中的man和everything. 引导定语从句的词，叫关系代词和关系副词。比如who,whom,that,which,wh ere,when,why等关系词三重作用：①连接主从句；②指代先行词；③在定语从句中担任句子成分。 The man who lives next to me sells vegetables. 该句中，who lives next to me是定语从句，修饰先行词the man，“who”是引导定语从句的关系词，代替先行词the man，在定语从句中作主语。二、关系词引导定语从句的关系代词有who,whom,which,that,whose,as等和关系副词w here,when,why等。关系代词和关系副词在定语从句中担任句子成分。

1.用关系代词that,which,who,whom引导的定语从句 who指人，用作主语 whom指人，用作宾语 which指物，用作主语、宾语皆可 that指人和物，用作主语、宾语皆可 The teacher who visits our school today is from Guangzhou.

高考高中英语语法宾语从句考点总结

高考高中英语语法宾语从句考点总结宾语从句是指一个句子在复合句中作主句的宾语，它是使用最广泛的复合句之一，它也是中考的经常考查的知识点之一。宾语从句的使用主要注意五点：考点一注意正确使用引导词宾语从句的引导词的使用，分为以下三种情况：（1）如果用一个陈述句来充当主句的宾语，则由that 引导（that在口语或非正式文体中常省略）。如： He said (that) he would like to see the headmaster.他说他想见校长。 She said (that ) she would leave a message on his desk.她说她将在他的桌上留个便条。 Mr Wu said (that) he was interested in taking photos.吴先生说他对摄影很感兴趣。（2）如果用一个特殊疑问句来充当主句的宾语，则由连接代词who, whom, whose ,what, which或连接副词when, where, why, how引导。如： I don’t know where he is from.

我不知道他来自何方。 The chil dren didn’t know who Father Christmas is.孩子们不知道谁是圣诞老人。 He asked me why I was late for the meeting. 他问我为什么迟到。 Could you tell me how I can get to the railway station?你能告诉我去火车站的路怎么走。（3）.如果用一个一般疑问句来充当主句的宾语，则由连词if或whether引导。如： She asked me if she could borrow these books. 她问我她能否借这些书。 Could you tell me if there are any good museums in Newtown? 你能告诉我新镇是否有一些好的博物馆吗？ I am not sure if he will come to my birthday party. 我不太确信他是否会参加我的生日聚会。考点二注意正确使用时态当主句谓语动词是一般现在时时，从句可以根据实际情况使用相应的时态；当主句是一般过去时时，从句根据实际情况用过去时态的某一种。

高中英语语法之四种名词性从句

四种名词性从句(宾语从句、主语从句、同位语从句、表语从句)讲解与练习 ◆学习宾语从句学习宾语从句的连词、语序、时态和各种变化及特殊用法(直接引证变间接引语也在宾语从句的基础上还要进行人称、状语、少数动词和句型的变化)是为学习其它三种名词性从句(主从、表从、同位从)做铺垫，连词、语序、时态基本相同，只是后三种考点相对宾.语从句少的多，主要是对连词的应用进行考查。所以学好宾语从句是必要的。宾语从句三注意三特殊一注意:注意引导词(连词) 由陈述句转化而来的宾语从句，引导词为that，that 在口语或非正式文体中可省略;由一般疑问句转化而来的宾语从句，引导词为if或whether;由特殊疑问句转化而来的宾语从句，引导词为句子本身的特殊疑问词，即what, when，where 等。 Eg：Tom says(that)he will fly to Beijing tomorrow. 汤姆说他明天将要坐飞机去北京二注意:注意从句语序. 宾语从句的语序应该为陈述句语序即“主语+谓语+宾语+其他”。也就是说将疑问句转化成宾语从句时，一定要将疑问句语序转变成陈述句语序。 Can you tell me what he is doing能告诉我他正在做什么吗? <特别提醒>当疑问句在宾语从句中做主语时，语序不变。 Eg：Do you know what makes him so angry? 你知道什么事使他如此生气吗？ <特别提醒>如果宾语从句表示的是客观真理或是科学事实，其谓语动词仍用一般现在.时态。 Eg：Our teacher told us that the sun is much bigger than the moon. 老师告诉我们说太阳比月球大得多。 ◆主语从句(与宾词从句连词、语序、时态相同。只是不能用if, that 不可省;) (一)、主语从句是一个句子，在句子中作主语成分。 (二)，主语从句的特点 1.与宾语从句使用同样的连接词，只是if不能用; 1)、陈述句用that。 2)、一般疑问句用whether。 3)、特殊疑问句用特殊疑问词what, which, who,when, where, why, how等词引导。 2.以it为形式主语出现 Eg：1.It's true that the earth is round. That the earth is round is true. 2.表是否的意思时，不能用if代替whether. It hasn't been decided whether he'll come or not. Whether he'll come or not hasn't been decided. 3.从句语序为主谓宾正常语序。 Why didn't he come? Why he didn't come is not known. （三）特殊疑问词变化 Whoever=no matter who=any one who Whomever=no matter who=any one who
