高中英语语法讲义——名词性从句(主从、表从、宾从,同从)
高中英语语法讲义---- 名词性从句（主从、表从、宾从，同从）1，陈述句做名从用连词that + SV, that 表主句肯定从句完整，不做成分。
主从可用it 做形式主语，宾从第一个that 可省略。
You study hard.主从：That you study hard is known to us.= It is known to us that you study hard.表从：My opinion is that you study hard .宾从：I think (that) you study hard. …and that (不能省略)….同从：My opinion that you study hard is known to us. *比较同从和主从！●一般抽象名词后对其进行解释和说明的完整句子就是其同位语从句，不完整就是定语从句。
I appreciate your idea that we have an exam every week. （that后完整—同从）I appreciate your idea that you came up with last time.（that后不完整---定从）2，一般问句做名从用连词whether(是否) + SV，whether表主句不肯定从句完整，宾从中可用if（介词后或宾从后有or not时只用whether）。
Does your friend like English ?主从：Whether your friend likes English isn’t clear .=It isn’t clear whether your friend likes English.表从：My question is whether your friend likes English.宾从：I don’t know whether/ if your friend likes English.同从：My question whether your friend likes English isn’t clear.3, 特殊问句做名从用疑问词（连词）+ SV, 疑问词做主语时直接+谓语。
连接代词（what/which/who/whose…）接不完整从句，连接副词（when/where/why/how）接完整从句。
Where did you go just now ?主从：Where you went just now isn’t clear.= It isn’t clear where you went just now.表从：My question is where you went just now.宾从：I wonder where you went just now.同从：My question where you went j ust now isn’t clear.●当主句为现在时态从句时态不受影响，当主句为过去时态从句就应该变成过去的某种时态，但客观真理总用一般现在时，有固定过去时间总用过去时。
高频考点1，当主从句都缺成分时指物用what/whatever/whichever(有范围), 指人用whoever / whomever(做宾语).The buildings have been built in _what_ was farmland. _What_ you need is courage.The prize will be awarded to _whoever_ has won the game. You can choose _what/whatever/whomever_ you like.Of all, you can choose _whichever_ you like .2, No matter+疑问词，只能引导让步状语从句（主从句逗号分开），疑问词+ever 既可引导让步状从，又可引导名从（从句在主句中做成分）。
_No matter who / whoever-has broken the law , he ‘ll be punished ._Whoever_ has broken the law will be punished.3, 抽象名词（fact, news/word, hope, desire, thought, suggestion, idea, problem, possibility/chance ,rumor, concept…）后常用that 引导同从。
News /word came that you had passed the exam.There is no possibility/ chance that he’ll come.解题方法：1，看主句表肯定还是不肯定，主句肯定从句完整根据句意从that和连接副词中选择；从句不完整根据句意看所缺成分从连接代词中选择。
2，不肯定时从句完整根据句意从whether 和连接副词中选择；不完整时根据句意看所缺成分从连接代词中选择。

• (1)主语从句
• 就是在复合句中作主语的从句。主语从句常用that, whether, who, whom, whose, what, which, when, where, how, why, whatever, whoever等引导。如： • Whether he will be able to come remains a question. 他是否来还是问 题。 • That China is a great socialist country is well known. 众所周知，中国 是一个伟大的社会主义国家。 • 注：为避免头重脚轻，使句子平衡，常用it作形式主语，而将主语从句 后置。如上述第二例常说成： • It is well known that China is a great socialist country. • 但是，由连接代词what, whatever, whoever等引导的主语从句一般不 能用形式主语。如： • What he found surprised me greatly. 他的发现使我非常吃惊。 • Whoever is finished may rest. 凡是做完工的人都可以休息。
规律四：主语从句和宾语从句在适当的情况 下可以借助 “it” 而后置。

名词性从句——
高中英语语法
在句子中起名词作用的句子叫名词性从句 (Noun Clauses）。 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，因此根据它在句中不同的语法功能。名词性从句又可 分别称为主语从句、宾语从句、表语从句和同位语从句。 这几类从句用法复杂、学习难度较大，考生在考试中丢分现象严重。
名词性从句(宾语从句、表语从句、主语从句、同位语从句)讲解素材 高考英语语法总复习
名词性从句（宾语从句、表语从句、主语从句、同位语从句）讲解高考英语语法总复习复合句：主句+从句意思上来讲主句是主要的。
但是从句才是我们学习的重点。
从句有各种各样的变化，从句要作不同的成分的，主句与从句间要加不同的连接词，可能有时候还要倒置。
例句：America's new plan to buy up toxic assets will not work unless banks mark assets to levels which buyers find attractive.America's new plan to buy up toxic assets will not work（这一部分为主句）。
unless从句1前的连接词。
banks mark assets to levels 从句1。
表示条件的从句。
如果...which从句2前的连接词。
buyers find attractive 从句2。
修饰前面levels的定语从句。
（一）名词性从句（当成名词来用的句子）包括：1、宾语从句（最重要）；2、表语从句（最不重要）；3、主语从句（一般重要）；4、同位语从句（一般重要）。
4种从句的写法一样，不一样的是位置不一样。
先看：1、宾语从句（最重要）1）含义：是一个作宾语的句子，位置是把它放到主句里作主句的宾语。
例句：The fossil record shows that many species have endured for millions of years.全句是一个主句，但是that many species have endured for millions of years作了该主句的宾语。
即that many species have endured for millions of years为宾语从句。
2）宾语从句的写法：先写两简单句，其中一个简单句作主句时省略掉宾语，然后将另一个简单句接到作主句的宾语位置当宾语即可，但是要注意连接词的使用。

高中英语名词性从句精讲
高中英语名词性从句精讲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,即名词性从句（包括主语从句,宾语从句,表语从句,同位语从句）、形容词性从句（即定语从句）、副词性从句（即状语从句,包括时间、条件、结果、目的、原因、让步、地点、方式等）。
在句子中起名词作用的句子叫名词从句(Noun Clauses）。
名词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、同位语等，因此根据它在句中不同的语法功能，名词从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。
引导名词性从句的连接词可分为三类：（1）从属连接：that, whether, if（不充当从句的任何成分）（2）连接代词：what, whatever, who, whoever, whom, whose, which.（3）连接副词：when, where, how, why名词性从句知识点汇总1名词性从句的分类名词性从句，包括四种从句，即主语从句、宾语从句、表语从句、同位语从句。

如：1.That she will help me made us happy.（主语从句）2.I can understand what he said.（宾语从句）3.This is where I was born.（表语从句）4.The fact that a heavy earthquake happened made me crazy.（同位語从句）2名词性从句的连接词分类1.that（无含义，不充当成分）2.whether,if（有“是否”的含义，但不充当成分）3.连接代词：what, whatever, who, whoever, whom, whomever, whose, which, whichever.（在从句中做主语、宾语、表语和定语）连接副词：when, whenever, where, wherever, how, however, why （在从句中做状语）4. as if,as though,because（不充当成分，在名词性从句中只引导表语从句）3连接词 that 在名词性从句中可以省略的三种情况1.it 做形式主语，that引导主语从句时It is said (that) he has been studying abroad.据说他一直在国外学习。
高中名词性从句讲义
名词性从句一．概述：在句子中起名词作用的各种从句统称为名词性从句。
根据它们在句中的语法作用，这类从句又可分为主语从句、表语从句、宾语从句和同位语从句。
二．名词性从句连接词1.连接词that；不充当句子成分; 无词义; 只起连接作用。
2. if/whether;意为“是否”，有词义2; 不做句子成分; 起连接作用3.连接代词：what(ever), which(ever), who(ever), whom(ever), whose(ver)有词义; 引起从句; 且在从句中充当一定的句子成分，常做从句中的主语、宾语、表语和定语。
4. 在名词性从句中一律用陈述句的语序，即使从句表达的是疑问含义。
三．if, whether的区别1.引导主语从句时，如果主语从句放在句首，只能用whether不能用if引导，但是如果用it 做形式主语，而把主语从句放在句末时，也可以用if引导.2.引导宾语从句时常放在动词know, ask, care, wonder之后，if和whether均可。
少数动词，如: leave, put, discuss, doubt后的宾语从句常用whether. 。
3.在介词后面的宾语从句中，在表语从句、同位语从句中，表“是否”，只能用whether；4.whether和if都可以和or not连用,但是whether 之后可以直接跟or not,而if不可以。
I don’t know whether or not I will stay.（只能用whether）5.在不定式前只能用whether.如：I can’t decide whether to stay. 我不能决定是否留下。
四．名词性从句以考查引导词为主，同时考查时态，语序，与其它从句的区别以及混同虚拟语气的考查。
一．主语从句1.主语从句定义：在复合句中充当主语的句子叫做主语从句。
That he will succeed is certain.Whether wild life can be well protected is of great importance.Who will go makes no different.Which kind of food is the best is still not certain.What is needed for the space trip is careful preparation.Whoever comes is welcome.How we can help the twins will be discussed at the meeting.When they’ll start the project has not been decided yet.Where he hid the money is to be found out.Why dinosaurs died out remains a puzzle.单个主语从句作主语时，谓语动词用单数形式。
高中英语语法之四种名词性从句
四种名词性从句(宾语从句、主语从句、同位语从句、表语从句)讲解与练习◆学习宾语从句学习宾语从句的连词、语序、时态和各种变化及特殊用法(直接引证变间接引语也在宾语从句的基础上还要进行人称、状语、少数动词和句型的变化)是为学习其它三种名词性从句(主从、表从、同位从)做铺垫，连词、语序、时态基本相同，只是后三种考点相对宾.语从句少的多，主要是对连词的应用进行考查。
所以学好宾语从句是必要的。
宾语从句三注意三特殊一注意:注意引导词(连词)由陈述句转化而来的宾语从句，引导词为that，that 在口语或非正式文体中可省略;由一般疑问句转化而来的宾语从句，引导词为if或whether;由特殊疑问句转化而来的宾语从句，引导词为句子本身的特殊疑问词，即what, when，where 等。
Eg：Tom says(that)he will fly to Beijing tomorrow.汤姆说他明天将要坐飞机去北京二注意:注意从句语序.宾语从句的语序应该为陈述句语序即“主语+谓语+宾语+其他”。
也就是说将疑问句转化成宾语从句时，一定要将疑问句语序转变成陈述句语序。
Can you tell me what he is doing能告诉我他正在做什么吗?<特别提醒>当疑问句在宾语从句中做主语时，语序不变。
Eg：Do you know what makes him so angry?你知道什么事使他如此生气吗？<特别提醒>如果宾语从句表示的是客观真理或是科学事实，其谓语动词仍用一般现在.时态。
Eg：Our teacher told us that the sun is much bigger than the moon.老师告诉我们说太阳比月球大得多。
◆主语从句(与宾词从句连词、语序、时态相同。
只是不能用if, that 不可省;)(一)、主语从句是一个句子，在句子中作主语成分。
(二)，主语从句的特点1.与宾语从句使用同样的连接词，只是if不能用;1)、陈述句用that。

高中语法解析从句的分类与用法
高中语法解析从句的分类与用法高中语法解析：从句的分类与用法引言：语法是语言的基础，而从句作为句子的一个重要成分，在阅读和写作中起着关键的作用。
在高中语法学习中，对于从句的分类和用法的准确理解和掌握是提高语言能力的关键之一。
本文将从句子结构、从句的分类以及从句的用法三个方面进行解析，帮助读者更好地理解和运用从句。
一、句子结构中的从句从句是一个可以独立成句但在主句中起到名词、形容词或副词作用的句子，它有自己的主语和谓语动词。
从句的存在使句子结构更加丰富多样，起到了丰富句子含义和表达复杂思想的作用。
1. 名词性从句：名词性从句在句子中作主语、宾语、表语或同位语。
常见的名词性从句包括主语从句、宾语从句、表语从句和同位语从句等。
例如：- 主语从句：What he said is true.（他说的是真的）- 宾语从句：I don't know where he went.（我不知道他去了哪里）- 表语从句：The fact is that they lost the game.（事实是他们输了比赛）- 同位语从句：I heard the news that she got the scholarship.（我听说她获得了奖学金）2. 定语从句：定语从句用来修饰一个名词或代词，并对其进行进一步解释或限制。
定语从句通常由关系代词（that, who, whom, which等）引导，并放在被修饰的名词或代词之后。
例如：- The book that I bought yesterday is very interesting.（我昨天买的那本书非常有趣）3. 状语从句：状语从句用来修饰一个动词、形容词或副词，表示时间、原因、条件、目的、结果等关系，并对主句进行补充说明。
常见的状语从句包括时间状语从句、原因状语从句、条件状语从句、目的状语从句和结果状语从句。
例如：- 时间状语从句：After she finished her homework, she went to bed.（她做完作业后就去睡觉了）- 原因状语从句：He failed the exam because he didn't study hard.（他考试不及格是因为他没有用功学习）- 条件状语从句：If you come early, we can have lunch together.（如果你早点来，我们可以一起吃午饭）- 目的状语从句：She studied hard so that she could pass the exam.（她努力学习以便能通过考试）- 结果状语从句：He was so tired that he fell asleep immediately.（他太累了，结果立刻睡着了）二、从句的分类与用法从句根据从属关系和在句中的作用可以分为几种类型，并在句子中扮演不同的角色。
