(完整版)表语从句(经典)

表语从句

一．定义：表语从句就是用一个句子作为表语。说明主语是什么或者怎么样，由名词、形容词或相当于名词或形容词的词或短语充当，和连系动词一起构成谓语

二．引导表语从句的关联词的种类：

(1)从属连词that。在从句中不做成分。

如：The trouble is that I have lost his address.

麻烦是我把他的地址丢了。

The reason was that he was late for school.

原因是他上学迟到了

(2)从属连词whether, as, as if。

如：1. He looked just as he had looked ten years before. 他看起来还与十年前一样。

2. The question is whether they will be able to help us. 问题是他们是否能帮我们。

注：（从属连词if一般不用来引导表语从句，但as if 却可引导表语从句）。

如：All this was over twenty ye ars ago, but it’s as if it was only yesterday.

这都是20多年前的事了，但宛如昨天一样。

The key is whether we can solve the problem.

关键是我们是否能解决问题。

注：（能跟表语从句的谓语动词一般为系动词be, seem, look，sound等）。

如：He looked just as he had looked ten years before.

他看起来还与十年前一样。

It sounds as if someone is knocking at the door.

听起来好像有人在敲门。

(3)连接代词who, whom, whose, what, which, whoever, whatever, whichever在表语从句中做主语、宾语等。如：The problem is who we can get to replace her.

问题是我们能找到谁去替换她呢。

That was what she did this morning on reaching the attic. 那就是她今晨上了阁楼干的。

The problem is who we can get to replace her.

问题是我们能找到谁去替换她呢

这就是他们曾经住过的地方。

That is why he didn't come here.

这就是他为何没到这儿来的原因。

The question is how he did it.

问题是他是如何做此事的。

(5)连词because可引导表语从句。

如：I think it is because you are doing too much.

我想这是因为你做得太多。

It's just because he doesn't know her.

这是仅仅因为他不认识她。

That's because he didn't understand me.

那是因为他没有理解我。(That's because...强调原因) That's why he got angry with me.

那正是他对我生气的原因。(That's why...强调结果)

(6)解释：在一些表示“建议、劝说、命令”的名词后面的表语从句中，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。

三．系动词分类:

1、分为两大类：完全系动词（其后只能跟表语的动词，如be, seem）和半系动词（其后既可跟表语作系动词用法，也可跟宾语或状语作实义动词用，如look）

eg：1. He looked sadly at the boy.(“看着”，实义动词用法)

2 .He looks a clever boy .（“看起来”，系动词用法）

3. He looks at a clever boy.（“看着”，实义动词用法）在英语中，某一动词是多义词，既有实义动词用法，又有系动词用法。

分为四类：A．五大感官系动词B．状态系动词C．动态系动词D．双谓语系动词

A．五大感官系动词，描述一种感官性质。由实义感官动词变化而来，都是半系动词。

宾语从句与表语从句.

【本讲教育信息】 一. 教学内容： 名词性从句——宾语从句与表语从句 二. 知识精讲 在复合句中起名词性作用的句子叫名词性从句。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，根据它在句中不同的语法功能，因此名词从句又分为主语从句、宾语从句、表语从句和同位语从句。 （一）宾语从句 1. 概念及引导词 在复合句中起宾语作用的从句叫宾语从句。引导宾语从句的连接词有连接代词（who, whom, whose , what , which, whoever , whatever, whichever ）、连接副词(when , where , how, why )及从属连词(that , whether, if ). 例：John said （that）he was leaving for London on Wednesday. 约翰说他星期三要到伦敦去。 I am glad that you are satisfied with your job. 你对工作满意我感到很高兴。 She will name him whatever she wants to. 她高兴给他起什么名字就起什么名字。 That depends on where we shall go. 那取决于我们去哪儿。 2. 宾语从句的种类 常见的宾语从句有动词的宾语从句、介词的宾语从句和形容词的宾语从句三种。 （1）动词的宾语从句 They know that the habit may kill them.定语从句 他们知道这个习惯会害死他们。 They doubt whether or not Jack is a good student. 他们怀疑Jack是否是一个好学生。 They wanted to see which shops offered the best advice and service定语从句. 他们想了解哪家店提出的建议和提供的服务最好。 （2）介词的宾语从句 一般情况下介词后只能接wh- 类连接词引导的宾语从句，但but, except, besides等后可接that引导的宾语从句。 We are talking about what we’ll do next. 我们正在讨论下一步做什么。 I know nothing about him except that he lives here. 对于他，我只知道他住在这儿，其他一无所知。

同位语从句及同位语

10级A班第六组作业 同位语从句 一、同位语从句的概念在复合句中用作名词的从句叫同位语从句, 其主要用途就是对前面的名词做进一步解释说明该名词的具体内容。 可以跟同位语从句的名词通常就 是: news,fact,promise,question,doubt,thought,hope,message ,suggestion,word, possibility,order,fear,proof,belief,advise,demand,problem,request,truth,wish 例句: I just got word that he is not coming this evening 、 Wehaven 't yet settled the question where we are going to spend our summervacation 、The Mona Lisa is widely seen as proof that good looks can last for ever There is no doubt that he is guilty 、 There is great doubt whether he did so or not 、 二.同位语从句的先行词同位语从句的先行词通常就是抽象名词, 常见的有:idea, situation thought, fact, evidence, belief, doubt, fear, hope, question, theory, news, order, ability 例句: 等等。How did the cheats explain the fact that the Emperor didn't feel the new clothes in him? 皇帝觉得身上并没有穿上新衣, 对这个问题骗子就是怎样解释的? The news that his heath is failing made us sad 、 她健康状况不佳的消息使我们很难过。 I have no idea where they are spending their holidays 、我不知道她们在哪里度假。 The question who should do the work requires consideration 、谁该干这项工作的问题需要考虑 There is no doubt that he will come here again 、她会再来这里, 这就是毫无疑问的。He was tortured by the doubt whether he would accept their presents 、她被就是否接受她们的礼物这个疑虑所折磨着。 三.同位语从句的引导词 1、连词that 引导同位语从句 The idea that you can do this work well without thinking is quite wrong 、您认为不动脑筋就能做好这件工作的想法就是完全错误的。（作idea的同位语） He gabbed his suitcase and gave the impression he was boarding the Tokyo plane 她拿起了手提箱, 给人的印象就是她要登上飞往东京的飞机了。 以下名词常用于以上句型: advice, announcement, argument, belief, claim, conclusion, decision, evidence, explanation, fact, feeling, hope, idea, impression, information, knowledge, message, news, opinion, order, probability, promise, proposal, remark, reply, report, saying, statement, suggestion, thought, treat, warning, wish, word

宾语从句和表语从句详解与练习

宾语从句和表语从句详解 名词性从句指的是在整个句子中起名词作用的从句。这种从句可以做主语、宾语、表语、同位语等，所以这类从句包括主语从句、宾语从句、表语从句和同位语从句。各种名词性从句的结构都是相同的，即由if，whether，that和各种疑问词充当连接词，后接陈述语序。 例如：What they are doing seems very important．（主语从句） 他们在做的事似乎很重要。 My hope is that he will be the best student in the class．（表语从句） 我的愿望是他能够成为班上最好的学生。 Nobody knows who he is．（宾语从句） 大家都不知道他是谁。 I don't like the idea that money is everything．（同位语从句） 我不喜欢金钱就是一切这一观点。 引导名词性从句的连接词中，除了that，if和whether之外其它的都作从句中的一个成分。 【宾语从句】 在句子中作动词或介词宾语的从句叫做宾语从句。引导宾语从句的词有连词that，whether，if；连接代词who，which，what以及其强调形式whoever，whichever，whatever；连接副词when，where，why，how等。 例如：Do you know where the Greens live I have no interest in how rich he is． 宾语从句主要用于下面五种结构： 1．由that引导的宾语从句（that 引导宾语从句时，特别是在口语中可省略） The boy believes that he will travel through space to other planets． that引导的宾语从句多用于say，think，insist，wish，hope，demand，imagine，wonder，know，suppose，see，believe，agree，admit，deny，expect，explain，order，command，feel，dream，suggest，hear，mean，notice，prefer，request，require，propose，declare，report等后。 当主句谓语动词是think，believe，suppose，expect 等词，而宾语从句的意思是否定时，常把否定转移至主句表示。例如：I don’t think it is right for him to treat you like that．（＝I think it is not right for him …．） that不能省略的情况： （1）当句中的动词后接多于两个由that引导的宾语从句时，第一个that可省，但后面的that不可省。如： He said （that）you were too young to understand the matter and that he was asked not to tell you． （2）当主句的谓语动词与that宾语从句之间有插入语时，that一般不可省。如： Just then I noticed，for the first time，that our master was wearing his fine green coat and his black silk cap． （3）当that从句是双宾语中的直接宾语时，that不可省。如： I can’t tell him that his mother died． 2．由特殊疑问词引导的宾语从句 这样的宾语从句实际上是由特殊疑问句变化而来的，宾语从句要用陈述句语序。用于这种结构的动词常常是：see，say，tell，ask，answer，know，decide，show，find out，imagine，suggest，doubt，wonder，discover，understand，inform，advise等。

宾语从句和表语从句要点归纳

宾语从句和表语从句 一、宾语从句要点归纳 ★宾语从句的语序必须是陈述语序。 ★that在引导宾语从句时无词义，也不充当任何成分，且通常可以省略。但如果含有两个或两个以上的并列宾语从句时，通常只有第一个从句的that可以省略，其余从句的that一般不能省略。如： My uncle said (that) he would come and that he would also bring his son. ★whether和if都意为“是否”，通常情况下，二者都可以引导宾语从句；但在介词之后或与or not连用时，只能用whether。注意：当whether与or not 不连在一起时，口语中可用if取代whether，当然也可以用whether。如： I don't know if / whether there will be trains any more. They are worrying about whether they can get there in time. I don't know whether or not I should take his advice. I'm not sure if / whether the train will arrive on time o r not. ★有时可用it作形式宾语，而把真正的宾语从句后置。如： We have made it clear that we will learn to deal with var ious difficult problems. ★在第一人称I / we与动词 think, expect, believe, guess, suppose等连用，后接宾语从句时，通常将从句的否定转移到主句谓语动词，形成否定前移。如： I don't suppose you're used to this diet. 二、表语从句要点归纳 ★表语从句一定要用陈述语序。 ★可接表语从句的词除系动词be外，还有 appear, become, look, remain, seem, sound等连系动词。如：

简单句与宾语从句、表语从句、同位语从句英语语法培训教材

简单句与宾语从句、表语从句、同位语从句英语语法培训教材

1简单句与宾语从句 (2) 1.1陈述句作宾语 (2) 1.2一般疑问句作宾语 (3) 1.3特殊疑问句作宾语 (3) 2简单句与表语从句 (5) 2.1陈述句作表语 (5) 2.2一般疑问句作表语 (5) 3简单句与同位语从句 (6) 3.1陈述句作同位语 (6) 3.2一般疑问句作同位语 (7) 3.3特殊疑问句作同位语 (7) 本章小结 (8) 1简单句与宾语从句 名词从句的本质是用三种句子（陈述句、一般问句和特殊问句）充当四种句子成分（主语、宾语、表语和同位语）。所以，当用三种句子充当另外一个句子的宾语时，就构成了宾语从句。因此，本节内容安排如下： 1.1陈述句作宾语 1.2一般疑问句作宾语 1.3特殊疑问句作宾语 1.1陈述句作宾语 把“that＋陈述句”这一结构放在宾语的位置即构成宾语从句。请看例句： 1We know(that) the world is round.我们知道，地球是圆的。 2I think(that) a sound knowledge of grammar is indispensable to good writing.我认为扎

实的语法功底对良好的写作极为重要。 需要注意的是，只有宾语从句中的that才可以省去（在不影响对句意的理解的情况下），而主语从句、表语从句和同位语从句中的that一般不能省去。 1.2一般疑问句作宾语 把“whether/if＋陈述句”这一结构放在宾语的位置即构成宾语从句。请看例句： 1I don't know if/whether he needs my help我不知道他是否需要我的帮助。 2No one knew whether or not interest rates would rise 没有人知道利率是否会提高。 这里原来的一般问句是would interest rates rise，变成陈述句语序后成为interest rates would rise，然后为了保留疑问的意义又添加了whether or not，于是便有了whether or not interest rates would rise，在主句的谓语knew后面作宾语，即构成宾语从句。需要提醒的是，因为一般不说if or not，所以这里的连词不宜用if，而要用whether。 注意：只有宾语从句才可以用if引导，主语从句、表语从句和同位语从句一般都要用whether引导。 1.3特殊疑问句作宾语 把特殊疑问句变成陈述句语序后放在宾语的位置即构成宾语从句。请看例句： 1I have not decided whom I should vote for我还没有决定该投谁的票。 这里的特殊疑问词whom是作vote for的宾语，所以需将原来的倒装句whom should I vote for调整为陈述句语序whom I should vote for，然后作主句谓语decided的宾语，即构成宾语从句。 2No one knows exactly how speech began没有人确切地知道语言是如何产生的。 这里的特殊疑问词how是作began的方式状语，所以需将原来的倒装句how did speech begin调整为陈述句语序how speech began，然后作主句谓语knows的宾语，即构成宾语从句。 3Could you tell me where the post office is? 你能告诉我邮局在哪里吗？

(whoever=the person who) 来的人将受到欢迎。 （二）表语从句 1．定义：用作表语的从句叫做表语从句。 2．构成：关联词+简单句 3．引导表语从句的关联词的种类：

高考英语语法——同位语从句

Grammar—appositive clauses＆predicative clauses 名词性从句之同位语＆表语从句 同位语从句： I.明确概念与特征： 1. 同位语从句常放在名词之后，用来补充说明名词的具体内容。常用来接同位语从句的名词有news, idea, promise, question, doubt, wonder, fact, hope, wish, suggestion, advice, possibility, message, word, belief, information等。常用来引导同位语从句的连词有that, what, who, whether以及连接副词where, when, why, how 等。如： The news that their children couldn’t come back on time worried all the parents. I had no idea when the storm would end. 2. 不过有时候为了保持句子结构平衡，同位语从句也不一定直接放在名词后，而会出现隔离情况。如： Word came that the sports meet had been put off. Suddenly a good idea occurred to me that I could buy my teacher a gift. 3. 同位语从句前名词的数 同位语从句前的名词通常用单数形式，并且往往带有限定词加以修饰。如：Where did you get the idea that I could not come? Give me your promise that you will come to our party this evening. Exciting word came that I passed the exam. II. 正确选用引导词 一般来说根据句意来确定相应的引导词，并且从句要用陈述句的语序。 1.that引导同位语从句时在句中不作任何成分，但不可省略； The idea that we play football after class is great. 2.在表示是否的意思时连词只能用whether而不能用if； The question whether you can go to an ideal university depends on your effort. 3.从句若缺少主语,宾语或定语用连接代词（what, who, whom, whose, which），若缺少状语用连接副词（when, where, how, why）引导。 I have no idea which mobile phone is the best—it’s a matter of personal taste. At last I made a decision that I would never come back again. The question what we should do with this situation is under discussion. All of us had no idea why he refused our help. The question why he didn’t attend the meeting puzzled us. We can’t solve the problem how we can travel faster than light. 4.在名词doubt“怀疑”后的同位语从句用whether连接；在no doubt“不怀疑”之后的同位语从句用that连接。例如： There is no doubt that we will win the final match. I have a doubt whether he will finish the job on time. III. 注意从句中的时态 一般来说同位语从句的时态要和主句的时态保持一致。但在表示请求、命令、建议等意思的名词后的同位语从句中的谓语动词应用(should) do，(如demand, wish, suggestion, advice，order等)后面的同位语从句要用虚拟语气。如 I have no idea when he will be back.

It+be+形容词(obvious, true, natural, surprising, good, wonderful, funny, possible, likely, certain, probable, etc.)+that从句。如： It is certain that she will do well in her exam. 毫无疑问她考试成绩会很好。 B.

(whoever=the person who) 来的人将受到欢迎。 （二）表语从句 1．定义：用作表语的从句叫做表语从句。 2．构成：关联词+简单句 3．引导表语从句的关联词的种类： (1) 从属连词that。如： The trouble is that I have lost his address. 麻烦是我把他的地址丢了。
