宾语从句与表语从句.
宾语从句和表语从句
一.宾语从句的定义置于动词、介词等词性后面起宾语作用的从句叫宾语从句。
宾语从句的语序必须是陈述语序。
谓语动词、介词、动词不定式，v.-ing形式后面都能带宾语从句。
有些形容词（afraid,sure,glad 等）之后也可以带宾语从句。
二.宾语从句中引导词的用法在复合句中作主句的宾语，引导词有：连词：that (that 常可省略),whether, if代词：who, whose, what ,which副词：when ,where, how, why 等。
（一）that引导的宾语从句（在非正式场合that可以省略）可跟that从句做宾语的动词有：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。
例句：The boy believes that he will travel through space to other planets.注意事项：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。
例句：I don’t think it is right for him to treat you like that.在以下情况中that不能省略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。
例句：He said (that) you were too young to understand the matter and that he was asked not to tell you.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。
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。
宾语从句和表语从句
This/That is because...
2.表语从句中whether 表示是否时不能用if 替代。
Bye-bye
宾语从句的语序
陈述句语述——
主语+谓语+宾语+其他
宾语从句的时 态由句意决定
一般过去时
过去时态 表示客观真理时用一般现在时
否定前移
主句谓语动词是
think,believe,suppose,expect 宾语从句的意思为否定时，否定词前移到主句。
eg.我认为他不会成功。
宾语从句的位置
动词和介词之后
引导词 连词：that,whether,if 代词：which, who,what,whose whichever,whoever,whatever 副词：when,where, why,how(however) that 无意义只起连接作用 固定用法：1.but that;except that 2.用it作形式宾语的宾语从句，与that 搭配。 eg.We think it very important that every student should study hard at English .
I think (that)he will not (won't) succeed.× I don't think (that)he will succeed.√
doubt 接宾语从句的用法
eg.I doubt whether/if he will keep his word.
I don't doubt that he will keep his word. Do you doubt that he will keep his word? 当主句是肯定式时，用whether/if 引导宾语从句 当主句是否定或者疑问式时，用that引导。
高中英语知识点归纳宾语从句与表语从句的区别
高中英语知识点归纳宾语从句与表语从句的区别宾语从句和表语从句是英语语法中两个重要的从句类型。
尽管它们在形式和用法上有些相似，但它们之间存在着明显的区别。
本文将对宾语从句和表语从句进行详细归纳和比较分析。
宾语从句（Object Clauses）宾语从句是一个句子，被用作主句中的宾语。
它通常回答了主句中的动词或介词所问的疑问。
通常有三种类型的宾语从句：陈述句型、疑问句型和祈使句型。
以下是宾语从句的特点和用法：1. 宾语从句常常由连接词引导，如that、whether、if等。
例句：He asked me whether I had finished my homework.2. 宾语从句中的谓语动词常按照陈述句的语序来构造，即主语+谓语（不需要使用助动词do/does/did）。
例句：She told us that she was going to study abroad.3. 宾语从句不加标点符号与主句隔开。
例句：I don't know if I can attend the party.4. 宾语从句可以出现在动词宾语的位置，也可以出现在介词宾语的位置。
例句：I believe that he is telling the truth.They are discussing whether to go on a trip.表语从句（Predicate Nomination Clauses）表语从句用来说明主语的身份、状态、特点等，并与系动词（如be、seem、appear等）连用，充当系动词的宾语。
以下是表语从句的特点和用法：1. 表语从句通常由连接词引导，如that、whether等。
例句：His dream is that he becomes a successful businessman.2. 表语从句中的谓语动词与主从句的主语保持一致。
例句：The problem is that we have run out of time.3. 表语从句不加标点符号与主句隔开。
宾语从句和表语从句详解
宾语从句和表语从句详解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, e_pect, e_plain, 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, e_pect 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 notto 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 greencoat 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.I can t decide which book I should buy.3.由whether(if)引导的宾语从句I wonder whether(if) they will come to our party.由whether(if)引导的宾语从句,实际上是一般疑问句演变而来的.意思是是否 .宾语从句要用陈述句语序.一般说来,在宾语从句中whether与if可以互换使用.4.宾语从句后带有宾补时,需用it作形式宾语,而把宾语从句放在句后,这时that不省略.例如:He thought it wrong that they left the child alone at home.【表语从句】在句子中作表语的从句叫做表语从句.引导表语从句的词有连词that,whether;连接代词who,what,which;连接副词when,where,how,why以及其它连词as if,as though,because等.例如:The question is whether it is worth reading.They are just what I want.That s why they were late.1.含有表语从句的复合句中的主语通常是fact,truth,e_planation,problem,opinion,view等.如:The fact is that fish can t go without water.事实是鱼离开水不能存活.2. as if (as though)也可以用于表语从句.但多是以下面形式出现.主语+look(seem)as if+从句如:It looked as if it was going to snow.It seems as if there will be a quarrel soon.注意:不用 if 引导表语从句.reason做主语时,表语从句应由that引导,不用because. that 引导表语从句时,通常不能省略.专项练习（附答案）1.

宾语从句与表语从句
宾语从句与表语从句一、宾语从句1.that 引导的宾语从句that引导宾语从句时无意义，也不充当任何成分，且通常可以省略eg: I made it clear that I was determined to carry out this plan.我已表明决心执行这个计划。
2.whether/if 引导的宾语从句wether/if 作“是否”讲，常用在ask, care, find out, know, wonder 等动词后。
Eg: I wonder if/ whether he can come tomorrow.在下列情况下一般只用whether, 不用if:(1)引导主语从句并在句首时；（2）引导表语从句时；（3）引导从句作介词宾语时；（4）从句后有“or not”时；（5）后接动词不定式时；3.特殊疑问词引导的宾语从句此类词主要包括连接代词who, whom, whose, what, which 和连接副词when, where, how, why.这些词在句中都承担一定的成分，但其后的从句一定要用陈述语序。
Eg: Do you know where Jim’s father works?你知道吉姆的父亲在哪里工作吗？4.宾语从句中的时态宾语从句的时态必须与主句呼应。
Eg: He says he is going to swim with his friend tomorrow.5.宾语从句中的否定转移在I/we think (believe, suppose, guess, expect, imagine 等)后面的从句里，如果含有否定含义，往往需要把否定词由从句转到主句，这叫做否定转移。
Eg：I don’t think you are fit for the job.注意：在发生否定转移的句子中，其反义疑问句的人称及助动词应与从句的人称和动词相对应。
Eg：I don’t think you are right, are you ?我认为你不正确，对吗？（不用do I）一、表语从句在复合句中作表语的从句叫表语从句，引导表语从句的连接词主要有：连接代词who, whom, whose, what, which; 连接副词when, where, how, why 及从属连词that, whether, as if, because 等。
宾语从句和表语从句的区别和联系
宾语从句和表语从句的区别和联系
二者的结构不同。
宾语从句的结构为主谓宾，表语从句的结构为主系表。
宾语从句和表语从句都属于名词性从句。
其作用跟名词在句中的作用相同。
故充当宾语的句子叫宾语从句，充当表语的句子叫表语从句。
1表语从句
表语从句就是用一个句子作为表语。
连接表语从句的连接词有：that,what,who,when,where,which,why,whether,how,whoever，whichever，whatever等。
还有如because,as if,as though等。
1.His suggestion is that we should stay calm. 他的建议是，我们应该保持冷静。
2.The question is when he can arrive at the hotel. 问题是，他什么时候可以到达酒店。
2宾语从句
宾语从句，是名词性从句的一种。
在主从复合句中充当宾语，位于及物动词、介词或复合谓语之后的从句称为宾语从句。
宾语从句分为三类：动词的宾语从句，介词的宾语从句和形容词的宾语从句。
连接词that引导宾语从句在句中无词义，不充当句子成分，口语中一般可以省略。
whether和if都可引导宾语从句，但whether后可紧跟or not；体的含义，意为“是否”。
if/whether不能省略。
宾语从句与表语从句
宾语从句与表语从句1.宾语从句，顾名思义即一个从句在复合句中充当宾语。
引导宾语从句的连词有：that,whether,if,who,whom,whose,that,which,when,where,how,why等。
Mary told me (that)………He looked at the invitation, wondering why……Pay attention to……..I wonder……2.表语从句，一个从句在复合句中充当表语称之为表语从句。
引导表语从句的连词有：that,whether, who, whom, whose, what, which, when, where, how, why, as though, as if, because 等。
This is how…….The question is ……It looks as if……It seemed as if…..The reason why……3.宾语从句与表语从句均属于名词性从句。
连词用法上，既有共同点，也有不同点。
(1)名词性从句应用陈述句式。
(2)that 引导名词从句时，只起着连接作用，在从句中，无意义，不充当语法成分。
在宾语从句中常可省略，但在主语，表语，同位语从句中一般不能省略。
在引导主语从句中，从句可用形式主语it 替代而将从句置后。
Everybody knows(that)………It hasn’t been decided(that)…….Don’t regret anything. The fact is that…..That you missed such a good chance……Finally he came to a conclusion that…….(3)whether/if 是否宾语从句，whether/if一般可互换，但在whether or not 结构中，应用whether。

引导词
要点一
总结词
表语从句的引导词包括that、whether、what、who、 whose等。
要点二
详细描述
that是最常用的引导词，用于引导描述性或解释性的表语从 句，如"The fact is that we won the game."（事实是我们 赢了比赛）。whether用于引导表示选择或疑问的表语从句， 如"The question is whether we should go or stay."（问 题是我们要走还是留下）。what用于引导含有疑问代词的表 语从句，如"The problem is what we should do next." （问题是接下来我们应该做什么）。who和whose用于引导 含有疑问代词的表语从句，如"The question is who should be responsible for the project."（问题是应该由谁负责这 个项目）。
03 从句与主句的关系
主从关系
主句是整个句子的核心，从句作为主句的延伸或补充，对主句进行解释、说明或 修饰。
从句在句子中的位置通常紧跟在主句之后，用连词引导，如“that”、“what” 、“when”等。
嵌套关系
嵌套关系是指一个从句内部又包含另 一个从句，即从句中又套有另一个从 句。
嵌套从句通常用于表达复杂的概念或 描述某种逻辑关系，使句子更加丰富 和多样。

宾语从句和表语从句
宾语从句和表语从句Debbie区别表语和宾语•表语也叫补语，是主语补足语，对主语进行补充说明。
表语跟系动词连用，构成系表结构。
•She is a student.•is 是系动词，所以a student是表语。
•She likes the student.•likes 是实义动词，所以the student 是宾语。
•表语跟宾语的主要区别：区别实义动词和系动词•常用的连系动词：•1表示状态存在的词：be，感官动词（look、smell、sound、feel、taste）、seem、appear等等。
•2、表示状态持续的词：keep、prove、stay、remain、turn （out）等等。
•3、表示状态转变的词：become，come、fall、get、grow、make等等•The borscht tastes marvelous。
（这罗宋汤尝起来味道太好了。
）•She looks nice.（她看起来漂亮极了）•The leaves are turning brown.(树叶在变黄)•It’s getting late.(天色渐晚了)•实义动词：表示实际意义和动作的动词•They owns all the cars.•He cooks good meals.•宾语分直接宾语和间接宾语。
直接宾语通常指及物动词的承受者，是动词直接涉及的人或者物。
而间接宾语表示动作是对谁或者为谁而做。
•直接宾语和间接宾语：•He offered Peter a job。
•He offered a job to Peter.•My friend present me a necklace.•My friend present a necklace to me.•表语和宾语的区分：•1.The lady will make a doctor.•(这位女士将成为一名博士)•2.The boy will make a model plane.•（这个男孩儿将做一个飞机模型）•The lady 跟doctor的关系，doctor是对the lady的一个补充说明，而model plane跟the boy 并不是补充和北说明的关系，model plane只是make （制作）这个动词的宾语。
宾语从句和表语从句
What is noun clause？
在英语的句子结构中，本来该由名词充当的主语、宾 语、表语和同位语，由一个句子来充当,这个句子就 叫名词性从句。

（2）当that作介词宾语时，that不可省掉。
（3）用it做形式宾语的宾语从句

宾语从句与表语从句
宾语从句与表语从句宾语从句宾语从句：在复合句中作句子宾语的从句。
任何宾语从句都有引导词；任何宾语从句都是陈述语序。
宾语从句既可以是：及物动词的宾语从句，如：He told us that they would help us through the whole work 也可以做介词的宾语从句，如：We are talking about whether we admit students into our club.宾语从句的类型：第一类：陈述句引导词为That(可以省略,只起到连接作用，在从句中不做成分)如：He knows (that) I’m a student. 他知道我是一名学生。
I must thank you (that) you help me do the work. 我必须谢谢你帮我做这个工作。
He knows (that) I’ll win the game. 他知道我将要赢得比赛。
第二类：疑问句引导词为whether或if (只起到连接作用，在从句中不做成分，但有意义翻译成“如果”)如：I don’t kno w whether he is a student. 我不知道他是否是一名学生。
I don’t know if he’ll come. 我不知道他是否将要来这。
第三类：特殊疑问句引导词为特殊疑问词（引导词在句中起连接作用，可在句中做主、宾、表、定语）如：I don’t know who will come here. (主语)I don’t know what he is.（表语）He’ll take back what I have said. （宾语）He’ll take back what book you read. （定语）注意1whether 和if 表示“是否”时的区别1. Whether可以用在各种名词性从句中，if 只能用在宾语从句和it 做形式主语时的主语从句中。
五大从句结构
英语五大从句结构概述英语中，从句是指不能独立成句，而需要依附于主句的句子。
从句可以在句子中担任不同的成分，如主语、宾语、表语、定语、状语等。
根据从句的功能，可以将从句分为五大类，即主语从句、宾语从句、表语从句、定语从句和状语从句。
本文将介绍这五大从句的基本概念、结构和用法，并给出一些例句和练习题，帮助读者掌握从句的用法和特点。
主语从句定义主语从句是指在复合句中作主语的从句。
主语从句通常位于谓语动词之前，有时也可以用it作形式主语，而将真正的主语从句放在谓语动词之后。
引导词主语从句常由以下词引导：连接词：that（有时可省略）疑问代词：who, what, which, whose疑问副词：when, where, why, howwhether/if（是否）结构主语从句有两种结构：主语从句+谓语动词+其他成分it+谓语动词+其他成分+主语从句用法主语从句可以用在以下情况：一般陈述句中，如：What he said is true.（他说的是真的。

宾语从句二．宾语从句宾语从句就是在复合句中作宾语的名词性从句，通常放在主句谓语动词（及物动词）或介词之后。
1. 作动词的宾语(1) 由that引导的宾语从句（that 通常可以省略）,例如： I heard that he joined the army.由whether (if) 引导的宾语从句，例如：I wonder whether you can change this note for me.(2)由who, what, which,引导的宾语从句She did not know what had happened.(3)由when, where, how, why引导的宾语从句2. 作介词的宾语例如：Our success depends upon how well we can cooperate with one another.3. 作形容词的宾语例如：I am afraid (that) I’ve made a mistake. That 引导的从句常跟在下列形容词后作宾语： anxious, aware, certain, confident, convinced, determined, glad, proud, surprised, worried, sorry, thankful, ashamed, disappointed, annoyed, pleased, hurt, satisfied, content 等。
也可以将此类词后的that 从句的看作原因状语从句。
4. It 可以作为形式宾语 It 不仅可以作为形式主语，还可以作为形式宾语，而真正的宾语that 从句则放在句尾，特别是在带复合宾语的句子中。
例如： We heard it that she would get married next month.表语从句：用作表语的从句叫做表语从句。
引导表语从句的连词有…as if , as though.The trouble is that I have lost his address .The question is whether they will be able to help us .The problem is who we can get to replace her .That was what she did this morning on reaching the attic .The question is how he did it .从属连词if一般不用来引导表语从句，但as if 却可引表语从句，如It looks as if it’s going to rain.All this was over twenty years ago ，but it’s as if it was only yesterday .同位语从句同位语从句在主从复合句中作某一名词的同位语,也就是说同位语从句说明被修饰名词的具体内容。

【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。
他和他的同学们不同的地方在于他把业余时间用在读书上了。
（3）形容词的宾语从句sure, certain , pleased , happy , afraid , surprised, sorry 等表示情感的形容词后可接宾语从句。
I’m not sure whether they will agree to such a plan.我不确定他们是否同意这样一个计划。
I’ m afraid that you have been given the wrong address.恐怕给你的地址不对。
3. 宾语从句应注意的问题。
（1）宾语从句中whether和if可互换，但作介词宾语或句中有or not时，用whether.I am not sure whether /if he will come.=I am not sure whether he will come or not .我拿不准他是否会来这儿。
It depends on whether you can do the work wel l.这取决于你能否把工作做好。
（2）it 作形式宾语在宾语从句中，it通常作形式宾语，而把真正的宾语放到句末。
这种用法通常有两种情况：①find, consider, think, feel , believe , make 等动词后有宾语补足语时，常用it作形式宾语，而将真正的宾语后置。
I have made it clear that I will not accept the job.我已表明我不会接受这份工作。
He feels it his duty that he should serve the people heart and soul.他觉得全心全意为人民服务是他的职责。
②有些动词或短语如enjoy, love , like , hate, appreciate , take , see to , insist on , depend / rely on 等接宾语从句时，习惯上在从句前加形式宾语it。
You may depend on it(形式宾语) that I shall always help you.你可以信赖的是我会一直帮助你。
I would appreciate it if you could give me a hand.如果你能帮我一把，我会很感激（你的）。
I hate it when people ask me for money.我不喜欢别人向我借钱。
（3）否定前置在由I / We think (consider, suppose(猜想) , believe , expect , guess, imagine)等引导的从句里，如果含有否定含义，往往把否定词由从句转移到主句，构成否定前置。
I don’t(否定前置)think he can finish the work on time.我认为他无法按时完成工作。
I don’t suppose he cares, does he?我想他不在意，是吗？（4）宾语从句的语序宾语从句中的语序要用陈述语序。

He asked what was the matter with my computer.他问我电脑出什么故障了。
（5）宾语从句的时态如果主句中的谓语动词是现在时态，从句中的谓语动词不受主句谓语动词时态的影响，可以根据需要使用任何时态。
如果主句的时态是过去时态，从句一般应与主句的时态保持一致，但从句表示的是真理或客观事实时，从句的时态要用一般现在时态。
He says he is going to swim with his friend tomorrow.他说他打算明天和朋友去游泳。
The teacher asked the students what they were doing.老师问学生们在干什么。

②主句的谓语和that之间有插入语时，that不能省略。

③作介词的宾语时，that不可省略。

④it作形式宾语，宾语补足语之后有that引导的宾语从句时，that不可省略。

I demand that one of you should go there at once.我要求你们中有一人立即到那里去。
