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。
完整版初中英语状语从句讲解、练习与答案
状语从句状从句用来修主句中的，副和形容的从句叫状从句。
依照其含状从句可分状从句，地址状从句，条件状从句，原因状从句，果状从句，比状从句，目的状从句，步状从句。
1. 状从句(1) 状从句常用when, as, while, before, after, since, till, until, as soon as等来引。
比方：It was raining hard （ rain hard 下大雨）when got to school yesterday.While he was doing his homework, the telephone rang.As he walked along （沿着走）the lake, he sang happily.He had learned a little Chinese before he came to China.After he finished middle school, he went to work in a factory.(2)在状从句里，平常不用将来，用在表示将来的作或状。
比方：I ’ ll ring you up as soon as I get to New York.I will tell him everything when he comes back.He won ’ t believe it until he sees it with his own eyes.(3) 在有 till 或 until 引的状从句的主从复合句里，若是主句用必定式，其含是“向到达⋯⋯”，只能用延性。
若是主句用否认式，其含是“直到⋯⋯才⋯⋯” , 在“⋯⋯ 以前不⋯⋯” ,可用瞬。
比方：The young man read till the light went out （熄） .Let ’ s wait until the rain stops.We won’ t start until Bob comes.Don’get off （从下来）until the bus stops.【 Till 是指直到某一特定事件发生的时候，而在那个时辰此后，该事情或状况仍将连续。
名词性从句详解及练习
各类从句详解英语从句可以分为名词性从句、定语从句和状语从句三大类：下面我们逐一进行说明：一、名词性从句（主语从句、表语从句、宾语从句、同位语从句）主语从句、表语从句、宾语从句和同位语从句在复合句中的充当的成分和其名称相同，分别作主句的主语、表语、宾语和同位语。
上述这四种从句均被称为名词性从句。
所有的名词性从句均不能用逗号分开，并且它们都用相同的关联词，关联词如下：①主从连词：that (无意义), whether (是否), if (是否)（在句子中不充当任何成分）②连接代词：who (谁), whom (谁), whose (谁的), what (什么), which (哪一个)③连接副词：when (什么时候), where (什么地方), how (怎样), why (为什么)主从连词只起连接作用，连接代词和连接副词除了起连接作用外，还充当从句某一个成分。
另外，可以用whatever, whichever, whoever, who(m)ever等连接代词引导名词性从句，来加强语气。
下面分别对各种名词性从句进行介绍（一）主语从句（subject clause）在主句中用作主语的主谓结构称之为主语从句。
例如：That he will come to the discussion is certain.他来参加讨论是确定的。
That the moon moves round the earth is well known to all of us.月球绕地球转动，这是我们大家都熟知的。
When the meeting is to be held has not yet been decide.会议什么时候召开还没有决定。
主语从句放在句首，句子常常显得比较笨重，因此通常可以把it放在句首，作形式主语，而将主语从句放在后面。
例如上面的句子可以分别改写为：It is certain that he will come to the discussion.It is well known to all of us that the moon moves round the earth.It has not yet been decide when the meeting is to be held.下面再举一些例句：What they are after is profit.他们追求的是利润。
(word完整版)初中英语必会三大从句汇总讲解,推荐文档
初中英语必会三大从句汇总讲解从句是相对于主句而言的，即它是从属于某一个主句，而不能单独作一个句子。
在英语中主要有三大从句，即：1. 名词性从句（包括主语从句，宾语从句，表语从句，同位语从句）2. 定语从句3•状语从句（包括时间、条件、结果、目的、原因、让步、地点、方式等）。
一、名词性从句1. 主语从句用作主语，如：That the earth is round is true. 地球是圆的是真实的。
2. 宾语从句用作宾语。
如：Do you know where he lives?3. 表语从句用作表语，如：My opi nion is that you should n ot go alo ne. 我的意见是你不应单独前往。
4. 同位语从句用于解释说明前面的名词。
如：The fact that the earth is round is true. 地球是圆的的事实是真实的。
（that 从句用于解释说明the fact）二、定语从句定语从句相当于一个形容词，用于修饰前面的名词。
如：The stude nt who an swered the questi on was Joh n. 回答问题的学生是Joh n.三、状语从句相当于一个副词，如：1. 时间状语从句When it rain s, I usually go to school by bus. 天下雨时，我通常坐公共汽车上学。
2. 条件状语从句If he comes tomorrow, you will see him. 如果他明天来，你就可以看见他。
（if引导的条件状语从句，其结构为：if +状语从句，+主句）。
要注意在状语从句中有一个规则是“主将从现”，即主句是将来时，则从句要用一般现在时表示将来。
3. 结果状语从句He returned home to lear n his daughter had just bee n en gaged. 他回家后得知女儿刚刚订婚了。
英语三大从句：怎样区分定语从句，宾语从句和状语从句（附习题）
英语三大从句：怎样区分定语从句，宾语从句和状语从句（附习题）我被学生最常问到的问题之一，就是怎样区分定语从句，宾语从句和状语从句。
今天我们对前面几节课的内容做一些提炼，探讨下怎样一眼就能辨别三大从句。
01 概念3大从句的区别均在于前面两个字：定语、宾语和状语：知道了这几个概念，这三种从句就很好理解了：定语从句：作定语/ adj.修饰先行词；在这里，dog “狗子” 是先行词，即“走在定语从句前面的名词”；定语从句 that shits a lot 其中的 that，指代了前面的 dog，告诉我们这是一条怎样的狗子：拉很多的狗子。
宾语从句：作宾语，放在动词或介词后面；第一句，宾语从句为普通的陈述句，放在think 这个动作后面，由连接词 that 引导。
第二句，宾语从句已经改成陈述句语序，原来人讲的话则是一般疑问句Do you let it go “你丫放不放手” ？该从句放在 depend on 的介词 on 后面，一般疑问句由 whether/ if 引导。
状语从句：作状语，给主句增加信息量。
状语从句，是3大从句中比较好记的一种：有个完整的主句，从句是提供更多信息的，比如上述例句告诉我们他为什么养狗。
只要熟悉九大状语从句的引导词（← 戳可查看），几乎一眼就能辨别出状语从句。
02 当堂练习现在，我们一起看几个句子找找感觉。
请判断下列句子是定语从句，宾语从句还是状语从句？>> 青铜1. If it is fine tomorrow, I will visit you.2. I helped an old man who lost his way.3. I don’t know what I should do next.>> 白银4. Mom hates our neighbor whose dog shits at our door.5. Mom hates our neighbor because his dog shits at our door.6. Mom asks our neighbor why his dog is so annoying.>> 黄金7. Stephen Hillenburg, who created ‘SpongeBob’, died at the age of 57.8. Stan Lee explained that he used a false name because he wanted to write a serious and great piece of literature someday. He did not want his link with comic books to be known when that happened.9. A Chinese scientist claims he successfully created the world's first genetically-edited babies.解析：确切而言，who created 'SpongeBob' 是非限制性定语从句，起补充说明的作用，去掉也不影响主句的完整性；非限制性的特征之一是从句前有逗号，具体参考前几期文章（← 戳可查看）。
高中英语从句精讲与练习(附答案)
高中英语从句讲解与练习（1)表语从句1．定义:用作表语的从句叫做表语从句。
2．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.（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 years 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.//It looked as if it was going to rain。
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.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。
三大从句讲解及练习(附有答案)
从句从句按其在主句中的句法功能可分为三类:即名词性从句、形容词性从句(即定语从句)和副词性从句(即状语从句)。
引导从句的词称作关联句。
一、名词性从句引导这些名词性从句的关联词包括:从属连词：that, if, whether;连接代词：who,whoever,whom,whomever,which,whichever,what,whatever,wh ose;连接副词where, when, why, how。
其中, 从属连词只起连接作用, 在从句中不充当任何句法成分,而连接代词和连接副词既起连接作用, 在从句中又充当一定的成分.不可省略的连词：1. 介词后的连词2. 引导主语从句和同位语从句的连词不可省略。
That she was chosen made us very happy.We heard the news that our team had won.比较：whether与if 均为"是否"的意思。
但在下列情况下，whether 不能被if 取代：1. whether引导主语从句并在句首2. 引导表语从句3. whether从句作介词宾语4. 从句后有"or not"Whether he will come is not clear.The fact is that he didn't go to the dinner party.I don't know if he will attend the meeting.1. 在含有主语从句的复合句中, 为保持句子平衡, 常用it作形式主语,而将真正的主语从句置于句末. That-从句作主语通常用it作先行词，而将that-从句置于句末，例如：It is quite clear that the whole project is doomed to failure.很清楚，整个计划注定要失败。
三大从句及反义疑问句及其答案
宾语从句语法讲解一、宾语从句根据引导词的不同可分为三种类型：1. 由that引导的宾语从句。
如：We knew （that）we should learn from each other.2. 由if/whether引导的宾语从句。
如：Please tell me if/whether you have been to America.3. 由who，where，how等连接代词或连接副词引导的宾语从句。
如：Can you tell me how I can get to the nearest post office？二、三要素1. 引导词如果从句是陈述句，引导词用that（that在口语或非正式文体中常省略）；如果从句是一般疑问句，引导词用if/whether；如果从句是特殊疑问句，引导词用由疑问词转换而来的疑问代词/副词。
2. 语序①陈述句变为宾语从句，语序不变，即仍用陈述语序。
如：He is an honest boy. The teacher said. →The teacher said（that）he was an honest boy.②一般疑问句和特殊疑问句变为宾语从句，语序变为陈述语序。
如：Does he work hard？I wonder.→I wonder if/whether he works hard.When did he leave？I don’t know. →I don’t know when he left.3. 时态①如果主句是现在的时态，从句的时态可根据实际情况而定。
如：I have heard（that）he will come back next week.②如果主句是过去的某种时态，那么从句的时态一定要用过去的某种时态。
如：He said（that）there were no classes yesterday.注意：如果宾语从句表述的是客观真理、自然现象等时，不管主句是什么时态，从句都要用一般现在时。
初中英语 中考复习：三大从句(含答案)
三大从句精讲点拨宾语从句1）．概念：用一个完整的句子做宾语,叫做宾语从句。
宾语从句可作主句谓语动词的宾语，也可做介词的宾语。
2）．易错点：1.引导词if 不能与or not 连用；whether 可以。
如：I don’t know whether I can pass the exam or not.2. could 开头的一般疑问句代表委婉请求，不代表过去式。
如：Could you tell me how I can go to the bus station?3. 从句为客观真理时，时态不受主句影响。
（注意三单哦！）如：The teacher told us yesterday that the earth goes round the sun.4. 当从句为What’s the matter？或What’s wrong 时，从句的语序不用改变。
★拓展：宾语从句的简化由特殊疑问词引导的宾语从句，若从句的主语在主句中出现过时，可简化为“疑问词+不定式”结构。
如：I don't know what I should do. → I don't know what to do .Can you tell me how I get to the hospital? → Can you tell me how to get to the hospital?★两种易混淆的结构定语从句1）．定语从句的概念【概念】在复合句中，修饰某一名词或代词的从句叫作定语从句。
The man （who lives next to us ） is a policeman.先行词 关系代词 定语从句被修饰的名词或代词放在先行词和定语从句之间，起连接作用，同时又作定语从句的一个成分。
关系代词有：who; which; that; who; whom 2）．详解引导定语从句的关系代词w3）．补充特殊情况只能用which ，不用that 的情况：(1) 在非限制性定语从中。

状从句状从句用来修主句中的，副和形容的从句叫状从句。
依据其含状从句可分状从句，地址状从句，条件状从句，原由状从句，果状从句，比状从句，目的状从句，步状从句。

比如：The young man read till the light went out（熄）.Let ’ s wait until the rain stops.We won’ t start until Bob comes.Don’ get off （从下来）until the bus stops.【Till 是指直到某一特定事件生的候，而在那个刻以后，事情或情况仍将持。
