3.需要注意的若干点
一.名词性从句的判断
名词性从句的类型包括主语从句、宾语从句、表语从句、同位语从句
判断下列从句的类型，用划出从句部分
1.Whether he will go there is not known .
2.Whoever comes is welcome.
3.Our success depends on how well we can cooperate with one another.
4.No one can be sure whether the earth will exist in a million years.

13.It’s known to all that the ear th is round.
14.He suggested that they should make a trip to Hong Kong next year.
15.I hate it when people speak with their mouths full.
二、名词性从句的连接词
一般规律：
针对从句成分，如果作的是主语、宾语、表语的话，这个词就是连接代词；如果作的是各种状语，就叫连接副词；
如果不作任何成分，就叫从属连词。
语序必须是陈述语序。
如下表：
从属连词that, if, whether
引导名词性从句
的连接词连接代词who, whom, what, whose, which, whichever, whatever, whoever
连接副词when, where, how, why，as if, because
三、特别注意若干点
1）I asked her __________ she had a bike.
2）I don’t know ___________ he is well or not.
3）___________ we will hold a party in the open air tomorrow depends on the weather. 4）It hasn't been decided____________ we shall attend the meeting.
5）We’re worried about ________ he is safe.
6）The question is _________ he should do it.
7）The doctor can hardly answer the question__________ the old man will recover soon.
8）I don’t know _______ to go or to stay at home.
2. that和whether的区别:that无意义，whether有疑问意义
I don’t know ________ he can join us or not.
I’m sure_______ he can join us.
It is none of your business _________ I love her.
It is none of your business _________I don’t love her.
I doubt____________ he can speak English. I don’t doubt ____________ he can speak English.
3.that，what的区分
what不但起连接作用，而且有具体意义，意为“所……的”（the thing(s) that），在从句中作主语，表语或宾语。
而that 在从句中无词义，只起连接作用。
简言之，从句中如果不缺少成分时，连接词用that，否则用what。
1）_______ he needs is more practice.
2）_______ he got the first place in the competition surprised us.
3）The truth is ______ I didn’t go there
4）He is not _______ he used to be 20 years.
5）_______impressed me most was ______such a little boy could play the violin so well.
4.表示坚持、命令、建议、要求的名词从句的语气要用虚拟语气,结构为should + do, should 可省略
It was ordered that all the soldiers____to the front.
A.should send
B.must be sent
C.should be sent
D.must go
5.whoever = anyone who + 定语从句
whomever=anyone whom +定语从句
What/whatever , when / whenever , where / wherever 的含义基相
同，只是后者比前者语气更重。
在意义上也有细微差别：
whatever 含义为anything that
whenever 含义为any time when
wherever 含义为any place where
改错：
1)Who leaves the room last ought to turn off the lights .
2)Mary hopes to become a friend of whomever shares her interests .
6.名词从句中须使用陈述语序
7.主句谓语动词是过去时态，从句也必须使用过去相应的时态。
(客观真理、格言谚语除外)

高中英语名词性从句知识讲解以及练习题 附答案
高中英语名词性从句知识讲解以及练习题附答案一、名词性从句概述名词性从句是一种充当名词作用的从句，通常在主句中作主语、宾语、表语或同位语。
它通常由引导词（如that, whether, if, who, whom, whose, which, what等）引导，并且从句中含有一个主语和谓语。
名词性从句的种类有很多，包括主语从句、宾语从句、表语从句和同位语从句等。
下面我们将逐一介绍这些从句。
二、主语从句主语从句作为一个名词，通常位于句首，是一个句子，主要作用是作为主句的主语。
引导主语从句的词：What (什么)；Whether (是否)；If (是否)；That (那个)。
例句：What he said is true. (他说的是真的。
)Whether it will rain tomorrow is uncertain. (明天是否会下雨还不确定。
)If you go, I will go too. (如果你走，我也跟着走。
)That he is coming is good news. (他来的消息是好消息。
)注意：主语从句的谓语动词通常要用单数形式。
What引导的主语从句通常用来表示“事物”的概念。
三、宾语从句宾语从句是一个名词，通常位于主句的动词后面，作为主句的宾语。
它可以由常见的宾语从句引导词引导，例如whether, if, that, who, whom, whose, what, when, where, how等。
引导宾语从句的词：Whether (是否)；If (是否)；That (那个)；Who (谁)；Whom (谁)；Whose (谁的)；What (什么)；When (何时)；Where (何处)；How (如何)。
例句：I know that he is coming. (我知道他要来。
)I wonder if he is telling the truth. (我想知道他是否说了真话。
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。

高中英语名词性从句课件(38张ppt)
(that在从句中不充当任何成份)
The idea （that/which） he gave surprises many people．
(that在从句中作gave 的宾语)
宾语从句须注意
1) 由疑问词引导的从句中, 词序按陈述句 顺序排列。
e.g. I wonder what he is doing. 注意：I wonder what was wrong /the matter
with him. 2)当主句的谓语动词是过去时的时候, 从句的 谓语动词应用相应的过去时。自然规律和客观 真理例外。
4) That在其他名词性从句中均不可省略，只有 在宾语从句中that有时可以省略，但在并列 的宾语从句中第二个that 不可省略。
e.g. He said (that) he would leave and that he would never come back again.
5) 否定的转移 若主句谓语动词为think, consider, suppose, believe, expect, fancy, guess, 等, 其后的宾语 从句若含有否定意义, 一般要把否定词转移到 主句谓语上, 从句谓语用肯定式。 e.g. I /we don’t think this dress fits you Well, does it?
3. 连接代词: what, whatever, who, whoever, whom,whose, which（哪个）： 不仅起到连接一个句子的作用,同时也是从句 的一个组成部分；从句不完整，缺成份。
