名词性从句讲义
名词性从句复习讲义 高三英语一轮复习
名词性从句复习注意:1.在名词性从句中,连接词的选择要根据从句的句意和上下文来确定。
2.当从句是陈述句时,通常使用连接词that(可省略,但在正式文体中建议保留);当从句是疑问句时,通常使用whether/if(表示选择或疑问)或连接代词/副词(表示具体的疑问内容)。
3.在宾语从句中,当从句是特殊疑问句时,其语序要调整为陈述句语序。
4.同位语从句与定语从句的区别在于:同位语从句是对前面名词或代词的具体内容的阐述或解释,而定语从句则是对前面名词或代词的修饰和限定。
一、主语从句定义:在句子中充当主语成分的从句。
引导词:that, whether, if, who, whom, which, what, whose, how, when, where等。
使用原则:主语从句通常位于句首,用于描述句子的主要动作或状态的执行者或承受者。
它可以是陈述句、疑问句或祈使句(但祈使句作为主语从句的情况较少见)。
构成:主语从句通常由连接词that(可省略,但当从句中有疑问词或表示否定、强调等意义的词时,通常不省略)或whether/if(表示选择或疑问)引导,后面跟完整的句子结构。

名词性从句讲义
名词性从句复合句包括两个或两个以上的主谓结构,其中一个是主句,另一个是从句(即在整个句子中作句子的一个成分,不能独立)。
按照从句在句中的功能,可分为名词性从句、定语从句和状语从句。
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。
因为这四种从句在整个句子中所起的作用相当于一个名词,因此,统称为名词性从句。
名词性从句需由连接词引导,连接词主要有三类:从属连词、连接代词、连接副词。
从属连词只起连接作用;连接代词和连接副词既起连接作用,又在从句中充当某一个成分。
另外名词性从句要用陈述语序。
考点一主语从句常引导主语从句的连接词有从属连词:that(无词义),whether/if(是否);连接代词:what (什么;所……的),who(主格,谁),whom(宾格,谁),which(哪一个),whose(谁的),whatever(无论什么),whoever(主格,无论谁),whomever(宾格,无论谁),whichever (无论哪一个)等;连接副词:when(什么时候),where(什么地方),why(为什么),how (怎样)等。
1.that引导的主语从句that只起连接作用,无词义,在从句中不作成分,一般不能省略。
如:That he will come and help us is certain.他来帮我们是肯定的了。
The pneumonia is a common disease is known to all.众所周知,肺炎是一种普通疾病。
2.whether/if 引导的主语从句whether引导的主语从句既可放在句首也可放在句尾,但if引导的主语从句只能放在句尾,前面需用it作形式主语。
Whether/if 只起连接作用,译成“是否”,在从句中不作成分。
如:Whether it is true remains a question.它是真是假,还是个问题。
(不能用if)It is doubtful whether the manager knew the details of the plan.经理是否知道计划的细节,还值得怀疑。
名词性从句讲义
强调:1)who和whom指人,what指物;
2)who和whom的区别是whom在从句中不能作主语。
作定语的有:whose,which,what,whichever,whatever
e.g. YBiblioteka u can choose whichever book you like.
If he will come is not known. (×)
2.if不能与or not直接连用。
e.g. if…or not (√) if or not (×)
whether…or not(√) whether or not (√)
四. “疑问词+ever”与“no matter+疑问词”的区别
强调,whose后不能加-ever。
2.连接副词连接副词在从句中作状语和表语。
when,where,why,how,whenever,wherever,however
e.g. That is why I am here.(作状语)
He decided to stay where he was.(作表语)
强调,why后不能加-ever。
3.特殊连接词
①that在句中不做任何成分,无意义,只起连接作用。
e.g. That he is not at home isn’t true.
②whether和if在从句中不作任何成分,但有意义“是否”。
e.g. I can’t decide whether I should go to her party.
I wonder where is he. (×)

certain
明确的
right

注:It is necessary/important/surprising/strange/unthinkable/unbelievable/incredible that+主语(should)+动词原形+其它。
e.g. It is necessary that a college student (should) master one or two foreign languages.
I don’t know whom you should depend on.

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、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引导名词性从句的连接词可分为三类:连词: that〔无任何词意〕whether, if 〔均表示“是否〞说明从句内容的不确定性〕as if ,as though〔均表示“好似〞,“似乎〞〕以上在从句中均不充当任何成分连接代词: what, whatever, who, whoever, whom,whose, which, whichever, whomever连接副词: when, where, how, why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.比拟:whether 与 if均为"是否"的意思。
但在以下情况下,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.大局部连接词引导的主语从句都可以置于句末,用it 充当形式主语。
It is not important who will go.It is still unknown which team will win the match.二 . 主语从句作句子主语的从句叫主语从句。
主语从句通常由附属连词that,whether, if 和连接代词what, who,which , whatever,whoever 以及连接副词how, when,where, why 等词引导。

名词性从句讲义一、基础概念在主从复合句中起名词作用的句子———名词性从句。
包括_____________、_____________、_____________和_____________。
对概念的理解,先抓住名词,例如:The news surprises us. 名词做主语He announces the news. 名词做宾语The news is a secrets. 名词做表语I know the book, The Little Prince. 名词做同位语前三种大家比较熟悉,但同位语是个什么角色呢?它其实就是名词的小跟班,紧跟在名词的后面补充前面的名词。
当主语、宾语、表语、同位语这四个角色想表达的意思再具体一些,就有了四种名词性从句。
主语从句The news surprises us.That he likes the girl surprises us.宾语从句He announces the news.He announces that he likes the girl.表语从句The news is a secrets.The news is that he likes the girl.同位语从句I know the book, The Little Prince.I know the news that he likes the girl.把原来的名词剪掉,换上一个连接词+完整的句子,这就是名词性从句。
that + he likes the girl连接词 + 完整的句子二、关于连接词这里至少有11个连接词可供选择:that 、whether 、if 、when 、where 、 why 、 how 、who、whom 、which、 what但是什么时候用哪个连接词是个问题,怎么办呢?在这里我们可以把它们分为三组:1、that :可以理解为陈述“确定的事”It is an undoubted fact that he likes the girl.That the money doesn’t grow on trees should be obvious.The idea that we invited him yesterday is quite good.2、whether /if: 可理解为陈述“不确定的事”It doesn’t matter whether he likes the girl or not.Whether the football game will be held depends on the weather.We worried about whether he was in good health.3、when 、where 、 why 、 how 、who、 whom 、which、 what:语境+语义就可以确定了__________ we will spend our holiday has not been decided.________ he likes the girl is still a mystery.I can’t understand ______ he refused.This is _______ I met my girlfriend.三、名词性从句的坑点(易错点)1、坑点一:陈述语序什么是陈述语序:我们平时说话的语气。

名词性从句 讲义1
名词性从句(Noun Clauses)名词性从句-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。
【注意】比较His words made me angry. (his words作主语)What he said made me angry. (what he said 作主语,是主语从句)宾语从句(The Object Clause)在复合句中用作动词或介词宾语的从句叫做宾语从句。
如:引导宾语从句的连接词:一. 从属连词:that, whether, ifthat:关联词that引导从句时无词义,也不充当句子成分,且通常情况下可以省略。
My aunt said that she would come and bring her daughter.※有时宾语从句太长会使句子显得笨重,因此常以it 作为形式宾语,而将宾语从句后置,以保持句子平衡。
1)在带复合宾语的句子中。
如:He has made it clear that he will not give in.We thought it strange that Jim did not come yesterday.2)连词that引导的名词性从句很少作介词的宾语,只用在except, but, in后。
其他一些介词的宾语从句如果由连词that引导,则需用it先行一步,作形式宾语。
如:Peter is a good student except that he is sometimes careless.You may depend on it that I shall always support you.※以下情况下that不能省略:1)句中的动词后接两个或两个以上的that从句作宾语时,第一个that可省,但后面的that 不可省。
如:He said (that) he couldn’t tell you right away and that you wouldn’t understand. 2)当主句的谓语动词与that宾语从句之间有插入语时,that一般不可省。
