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。
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。
名词性从句的三种类型及例句解析名词性从句是指在一个句子中充当名词的从句。
它可以作主语、宾语、表语和同位语等，并能够起到连接子句与主句的作用。
在英语语法中，有三种主要类型的名词性从句：宾语从句、主语从句和表语从句。
本文将详细解析这三种类型，并举例说明其用法。
一、宾语从句宾语从句作为一个整体出现在主句中的动词后面，充当主句的宾语。
它常常引导由that、whether/if、wh-疑问词引导的从句。
下面是一些例句：1. 主句：He asked me a question.宾语从句：He asked me whether I had finished my homework.解析：宾语从句"whether I had finished my homework"作为动词"ask"的宾语，表达了一个疑问。
2. 主句：She doesn't know the answer.宾语从句：She doesn't know what the answer is.解析：宾语从句"what the answer is"作为动词"know"的宾语，表示对答案的不知道。
3. 主句：They wonder if he will come to the party.宾语从句：They wonder if/whether he will come to the party.解析：宾语从句"if/whether he will come to the party"作为动词"wonder"的宾语，表达了对他是否会来参加派对的疑问。
二、主语从句主语从句作为一个整体出现在句子的最前面，充当主句的主语。
它通常由that引导，也可以由wh-疑问词引导。
以下是一些例句：1. 主句：It is important to learn a foreign language.主语从句：That she is a hardworking student is important.解析：主语从句"That she is a hardworking student"作为句子的主语，强调了她是一个勤奋的学生的重要性。
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。
当我们学习语法时，我们常常会遇到几种从句，包括宾语从句、状语从句、定语从句和表语从句。
下面逐个进行详细讲解，并给出相应的例句。
1. 宾语从句（Object Clause）：宾语从句用来做主句中的宾语。
它通常由连接词引导，如that, if, whether, what, where, who, whom, whose等。
例句：- I don't know what he wants.（我不知道他想要什么。
）- She asked if he could come to the party.（她问他是否能来参加派对。
）- They wonder where we are going.（他们想知道我们要去哪里。
）2. 状语从句（Adverbial Clause）：状语从句用来修饰主句中的动词、形容词、副词，表示时间、地点、原因、条件、结果等。
它通常由连接词引导，如when, while, because, if, although, since等。
例句：- We will go hiking if the weather is good.（如果天气好，我们将去远足。
）- He studied hard until he passed the exam.（他学习努力直到通过考试。
）- Although it was raining, they still went out.（虽然下雨了，他们仍然出去了。
）3. 定语从句（Relative Clause）：定语从句用来修饰主句中的名词或代词，对其进行限定或说明。
它通常由关系代词引导，如that, which, who, whom, whose等。
例句：- The book that I bought yesterday is very interesting.（我昨天买的那本书很有趣。
）- The person who is talking to Mary is my brother.（正在和玛丽说话的那个人是我哥哥。
