最新高三英语语法复习---名词性从句上课讲义
高三英语语法复习---名词性从句一、概说名词性从句，即指性质相当于名词的从句，它包括主语从句、宾语从句、表语从句和同位语从句。
名词性从句的连接词的选用依据“从句缺什么成分补什么成分”的原则。
解题时，应首先确定选用连接代词还是连接副词。
然后再根据题意选用具体的连接词。
如果名词性从句中缺少主语、宾语、表语或定语，则选用连接代词。
如果从句中缺少状语，则选用连接副词。
如果从句中不缺成分，而仅表示陈述事实，则用that引导。
如果含有“是否”意义，则选用whether或if。
二、名词性从句的一般引导词1.连接词that 只起连接作用，没有任何意思，也不充当句子成分，在宾语从句中可省略，但引导其他名词性从句时通常不省略。
如：I hope (that) you enjoy your holiday. 希望你假期过得好。
That he likes you is very obvious. 很显然他喜欢你。
2.连接词whether 也不充当句子成分，但有自己的意思，表示“是否”；引导宾语从句时，可换成if，但引导其他名词性从句时不能换成if。
He asked whether [if] I would show him the way. 他问我是否可以给他带路。
Whether it will do us harm remains to be seen. 是否对我们有害还要看一看。
(引导主语从句，不能用if 代替whether)3.连接代词who(m), whose, which, what 等，均有各自的意义，在从句中作主语、宾语、定语等。
如：That’s why she wanted to leave. 这就是她想离开的原因。
When we arrive doesn't matter. 什么时候到没有关系。
Tell me which one you like best. 告诉我你最喜欢哪一个。
4.连接副词when, where, why, how 等，也各自有自己的意义，在从句中作状语。

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。

第10节名词性从句第1课时高中英语语法精讲
知识点总结
名词性从句包括主语从句,表语从句,宾语从句和同位语从句. 其关联词有连接词that, if, whether.疑问代词 Who, whoever, what, which. 疑问副词When, where, how, why.等.
一、1.主语从句：
在句子中做主语, 它可以放在主句谓语动词之前, 但that引导的主从多数情况由it做形式主语, 而把主语从句放在主句之后:
eg: who did that is known to all .
It is interesting that you should like him.
一般情况下, 从句做主语, 谓语用单数. 但what引导的主语从句. 谓语动词视情况而定:
eg: What I need most are books.
What he wants is a book.
What I need is time.
常见用it作形式主语的复合结构
(1) it is +n +that clause
eg.It is a fact (a shame,a pity ,no wonder,good news) +that clause
(2) It is adj +that clause
eg.It is necessary (strange; important; wonderful;possible;likely)+that clause 用虚拟 (should)+v
(3) It is + done +that clause
eg.It is said;reported;believed;decided---+that clause
(4) It +vi +that clause
eg.It seems;happened;doesn’t matter;has turned out----+that clause
2. 表语从句：
在从句中做表语,位于主句中系动词之后:
eg: The question is who can complete the difficult task.
表语从句还可以用 as if 引导. eg: He looked as if he was going to cry.
The reason(why…/for…) is that…
It’s because (原因) It’s why (结果) The truth/trouble/problem is that…
3. 同位语从句：
它通常跟在名词后面, 进一步说明该名词具体内容. 引导同位语从句的名词主要有: fact, idea, hope, order, promise, word, question, belief, news, truth, suggestion, thought, problem, doubt;;information;condition等.一般用that引导.
eg: The news that our team has won the match is true.
Word came that our team won the match.
注意: which不能引导同位语从句.
4. 宾语从句：
宾语从句在句中做及物动词或介词宾语.
eg: We can learn what we did not know.
He will take to us about what he saw in the U.S.A.
如果主句的谓语动词是及物动词make, find, hear等. 则把宾语从句置于宾语补足语之后, 用it 做形式宾语.
eg: We find it necessary that we practise spoken-English every day.
另外某些做表语的形容词如: sure, happy, glad, certain等之后也可以带宾语从句.
eg: I am sure that he will succeed.
注意:
1. 双重疑问句. 否定前移的动词(think, believe, suppose, imagine, expect, guess等)后接特殊疑问词引导的宾语从句时,语序为特殊疑问词位于句首, 主句变成一般疑问句, 后面是陈述句.
eg: Who do you think is the best singer in your school?
Why do you think he was late?
二、特殊疑问词who、what、when等引导的宾语从句，应为特殊疑问词加上陈述句。
eg: He asked where Mr. Wang was.
但What’s the matter with sb? 和What’s wrong with sb? 除外
eg: —What’s the matter with you?
—What did she say?
—She asked what was the matter with me.
三、关联词if、whether均可使用情况：引导动词宾语从句时
eg: I wonder if (whether) the news is true.
注：if与 whether区别:
1.关联词只能用if情况：动词宾语从句，而且宾语从句部分是否定句时
eg: He considered if he couldn’t tell her the secret.（他考虑是否不应该把秘密告诉她）
I don’t care if it doesn’t rain.（我根本不在乎不下雨）
2.关联词习惯用whether情况：
a. 在主语从句、表语从句、同位语从句中
eg: The question is whether the film is worth seeing.
The news whether our team has won the match is unknown.
Whether we shall attend the meeting hasn’t been decided
yet.
b. 在介词后
eg: It all depends on whether they will support us.
c. 后面直接跟动词不定式时
eg: He does n’t know whether to stay or not.
d. 与or或or not连用
eg: We didn’t know whether or not she was ready.
e. 动词宾语从句在句首时
eg: Whether this is true or not, I can’t say.
f. 引导一个让步状语从句，表“不管”
eg: Whether he agrees or not, I shall do that.
注：doubt用法:
若doubt 一词做“怀疑”解释接宾语从句时，主句为肯定句用whether或if，主句为否定句或疑问句用that。
eg: I doubt whether/if he will come soon.
I do not doubt that he will come soon.
Do you doubt that he will come soon?。
