高中英语语法名词性从句
规律一：名词性从句在句中要用陈述语序
II．引导词的选择
1. ____ we can't get seems better than ____ we
have. A.What , what C. That , that
B. What , that D. That , what
2. It worried her a bit ____ her hair was turning grey. A．while C．if B．that D．for
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。
1.主语从句可以用it （作形式主语） 来替换成以下几种结构表达。 (A)It is clear/certain/likely /true/surprising that… （B）It is a pity/shame /good idea/no wonder that ...
The question of whether they are male or female is not important. I have not decided whether to go or not.
⑥ whether可引导一个让步状语从句表示 “不管”、“无论”，而if不能，但可以 引导一个条件状语从句表示“如果”如：
• (4)同位语从句 • 就是在句中作同位语的从句。它通常有放在thought, idea, news, word(=news), plan, doubt, question, fact, suggestion, belief等抽象名 词的后面，说明这些词的具体内容或含义。同位语从句大多由that引 导，也可由whether, how, when, where, why等引导，但不能由which 引导。如： • The idea that the earth is round is not a new one. “地球是圆的”这种 观点并不新鲜。He must answer the question whether he agrees to it or not. 他必须回答他是否同意此事这们一问题。 • I have no idea when he will set out. 我不知他什么时候出发。 • 注：有时，同位语从句并不紧跟在它所说明的词的后面。如： • The whole truth came out at last that he was a wolf in sheep’s clothing. 真相终于大白了，他原来是一只披羊皮的狼。
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。
因为主语、宾语、表语、同位语这四种成分均可以由名词构成，所以这四种从句在主句中都充当了名词的作用，故将这四种从句统称为名词性从句。
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。
高中英语语法：四种名词性从句讲解与练习
名词性从句名词性从句相当于名词，可分别作主句的主语、表语、宾语和同位语。
因此，名词性从句可分为主语从句、表语从句、宾语从句和同位从句。
引导词：主语从句就是在复合句中用作主语的从句，引导主语从句的引导词主要有三类：一是that；二是whether；三是那些可以用作疑问词的词语，如what, who, which, when, where, how, why等（一）引导名词性从句的连接词1、连接代词：who, whose, whom, what, which。
有词义，在从句中担任成分，如主语、表语、宾语、或定语等。
2、连接副词：when, where, why, how。
有词义，在从句中担任成分，作状语。
3、连接词：that, whether, if, as if。
that 无词义，在从句中不担任成分，有时可省略；if (whether), as if虽有词义，但在从句中不担任成分。
注意：连接代词与连接副词在句中不再是疑问句，因而从句中谓语不用疑问式。
连接代词与连接副词在从句充当句子成分，连接词whether 和if（是否），as if（好象）在从句中不充当句子成分，只起连接作用。
根据句义，如果连接代词与连接副词，whether、if 和as if都用不上时，才用that作连接词（that本身无任何含义）。
一、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。
2）、一般疑问句用whether。
3）、特殊疑问句用特殊疑问词what, which, who,when, where, why, how 等词引导。
2.经常隐身（以it为形式主语出现）。
例句：1.It's true that the earth is round.That the earth is round is true.2. 表是否的意思时，不能用if代替whether.It hasn't been decided whether he'll come or not.Whether he'll come or not hasn't been decided.3. 从句语序为主谓宾正常语序。

高中英语实用语法第十二章 名词性从句
名词性从句【知识精讲】在句子中起名词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，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。
一、引导名词性从句的连接词（一）引导名词性从句的连接词可分为三类：1.连词：that（无任何词意,陈述句充当名词性从句）whether ,if（均表示“是否”表明从句内容的不确定性，一般疑问句充当名词性从句）as if ,as though（均表示“好像”，“似乎”）以上在从句中均不充当任何成分2.连接代词：what, whatever, who, whoever, whom,whose, which. whichever, whomever3.连接副词：when, where, how, why（由特殊疑问句充当名词性从句）（二）、名词性that-从句1．由从属连词that引导的从句叫做名词性that-从句。
That只起连接主句和从句的作用，在从句中不担任任何成分，本身也没有词义。
名词性that-从句在句中能充当主语、宾语、表语、同位语和形容词宾语，例如：主语：That he is still alive is sheer luck.宾语：John said that he was leaving for London on Wednesday.表语：The fact is that he has not been seen recently.同位语：The fact that he has not been seen recently disturbs everyone in his office.形容词宾语：I am glad that you are satisfied with your job.2．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.●It's a pity that you should have to leave.（三）名词性wh-从句1．由wh-词引导的名词从句叫做名词性wh-从句。

适用文档名词性从句解说在复合句中起名作用的从句叫做名性从句。
它包含主从句、从句、表从句和同位从句。
名性从句是中学段的一个重要法目，在年的高考取几乎都波及到，而且每年的命各有化。
解析届高考名性从句考的焦点主要有以下六个方面1.考名性从句的序2.考引 that与 what 的区3.考 it 在名性从句中作形式主或形式的用法4.考 whether 与 if 的区5.考名性从句中的疑+ever 引的名性从句与no matter+ 疑引的状从句的区6.考名性从句的虚气法重点解析一、名性从句主从句、表从句、从句、同位从句，在整个句子中所起的作用，相当于一个名。
所以，四种从句通称名性从句。
引名性从句的接可分三：接： that, whether, if（不充任从句的任何成分）接代： what, whatever, who, whoever, whom, whose, which.接副： when, where, how, why1.主从句作句子主的从句叫主从句。
主从句往常由附属that ，whether ，if和接代what ，who，which ，whatever ， whoever 以及接副 how， when， where， why 等引。
that 在句中无，只起接作用；接代和接副在句中既保存自己的疑含、又起接作用，在从句中充任从句的成分。
比如：What he wants to tell us is not clear.他要跟我什么，不清楚。
It is known to us how he became a writer.我都知道他是如何成一名作家的。
Where the English evening will be held has not yet been announced.英晚会将在哪里行，没有宣告。
有防止句子重脚，常用形式主it取代主从句作形式主放于句首，而把主从句置于句末。
主从句后的一般用数形式。
