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。
从句类型及例子
从句类型及例子从句是一个句子的一部分，由一个主句和一个或多个从句组成。
从句可以分为名词性从句、形容词性从句和副词性从句。
下面将分别介绍这三种类型的从句，并给出相应的例子。
一、名词性从句名词性从句在句子中充当名词的角色，可以作主语、宾语、表语、同位语等。
名词性从句有三种类型：主语从句、宾语从句和表语从句。
1. 主语从句主语从句在句子中作主语，常常以that引导。
例子：- That he is late again is really annoying.（他再次迟到真是让人恼火。
）- Whether she will come to the party is still unknown.（她是否会来参加派对还不确定。
）2. 宾语从句宾语从句在句子中作及物动词或介词的宾语，常以that引导，也可以用whether/if引导。
例子：- He asked me if I had finished the report.（他问我是否已经完成了报告。
）- I don't know whether he will come or not.（我不知道他是否会来。
）3. 表语从句表语从句在句子中作表语，常以that引导，也可以用whether/if 引导。
例子：- The fact is that he is a talented musician.（事实是他是一位有才华的音乐家。
）- My concern is whether we can finish the project on time.（我关心的是我们是否能按时完成项目。
）二、形容词性从句形容词性从句用于修饰名词或代词，相当于一个形容词，一般由关系代词（如who, whom, whose, which, that）或关系副词（如when, where, why）引导。
1. 关系代词引导的形容词性从句关系代词引导的形容词性从句修饰先行词，在从句中充当某一成分。
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。

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。

【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. 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.他们想了解哪家店提出的建议和提供的服务最好。

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
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。

03 从句与主句的关系
主从关系
