名词性从句的引导词和用法
名词性从句的引导词和用法
名词性从句是指在句子中充当名词的从句,它可以在句子中作主语、宾语、表语、同位语等成分。在构建名词性从句时,需要使用特定的引导词来引导从句的内容。本文将详细介绍名词性从句的引导词及其用法。
一、引导名词性从句的词语
1. 从属连词
从属连词是引导名词性从句最常用的一类词语。常见的从属连词有:
(1)连接主语从句的引导词:that, whether, if等
例如:
- He said that he would come to the party.
- I wonder whether/if it will rain tomorrow.
(2)连接宾语从句的引导词:that, whether, if, what等
例如:
- She asked me what my favorite color was.
- We don't know if/whether he will pass the exam.
(3)连接表语从句的引导词:that, whether, if等
例如: - My belief is that honesty is the best policy.
- The question is whether/if he can handle the job.
(4)连接同位语从句的引导词:that, whether, if等
例如:
- The fact that she won the competition surprised everyone.
- There is no doubt whether/if he will achieve his goal.
2. 连接副词
有些副词也可以用来引导名词性从句,常见的有:where, when, why,
how等。
例如:
- I don't know where he went after the meeting.
- Can you tell me when the train will arrive?
二、名词性从句的用法
1. 主语从句
主语从句常常出现在句子的主语位置,用来说明句子的主语是谁。引导主语从句的常用词是that。
例如:
- That she is late for the meeting again is really annoying.
- Whether he can attend the party is still uncertain. 2. 宾语从句
宾语从句常常出现在动词后面,用来充当动词的宾语。根据不同的动词,宾语从句可由不同的引导词引导。
例如:
- She asked me why I didn't come to the party.
- He wonders if/whether she will accept his invitation.
3. 表语从句
表语从句常常出现在系动词后面,用来说明主语的具体情况,作为表语。常用的引导词有that, whether, if等。
例如:
- The most important thing is that you try your best.
- His biggest concern is whether/if he will succeed.
4. 同位语从句
同位语从句常常紧跟在名词后面,用来对名词进行解释或说明。常用的引导词有that, whether, if等。
例如:
- The idea that everyone should be treated equally is widely accepted.
- There is no doubt whether/if he will win the competition.
三、名词性从句的特点 1. 由引导词引导:名词性从句需要使用特定的引导词来引导从句,根据从句在句中的功能选择合适的引导词。
2. 充当不同成分:名词性从句可以充当主语、宾语、表语、同位语等不同句子成分。
3. 句子结构完整:名词性从句本身是一个完整的句子,具有主谓结构。
总结:
通过本文的介绍,我们了解了名词性从句的引导词及其用法。在构建名词性从句时,需要根据从句在句子中所起的作用选择相应的引导词。掌握名词性从句的用法,能够帮助我们更准确地表达自己的意思,丰富句子结构,使文章更加丰富多样。

1.what与that的用法区别 两者均可引导主语、表语、宾语从句,区别是what可在从句中用作主语、宾语或表语,意为
“什么”或“所……的”,而that仅起连接作用,本身没有实际意义,在从句中也不充当任何句子
成分(引导宾语从句时通常可以省略1:
He doesn’t know what she likes.他不知道她喜欢什么
What you say is quite right.你所说的相当正确。
I believe(that)he will come to see as.我相信他会来看我们的。
It’S a pity(that)he didn’t finish college.真遗憾他大学没毕业 另外,that可引导同位语从句,但what通常不用于引导同位语从句:
I had no idea that you were here.我不知道你在这儿
2.whether与if的用法区别
两者的用法异同要注意以下几点:
f1)两者均可引导宾语从句,表示“是否”,常可互换:
He asked if/whether we wanted a drink.他问我们是否想喝一杯
He didn’t tell me if/whether he would come.他没有告诉我他是否会来
【注】若是引导条件状语从句,则只能用if(意为“如果”)。 f21当引导一个否定的宾语从句时,通常用if而不用whether:
I don’t care if it doesn’t rain.我不在乎天是否下雨
【注】在个别词语(如:wonder,not sure等)后的从句否定式有时也可用whether引导:
1 wonder if/whether he isn’t mistaken.我想知道他是否错了
(31以下情况通常要用whether而不用if:

当what用作连接代词,引导名词性从句时,可引导主语从句、表语从句和宾语从句;它本身在从句中充当主语、宾语或表语。

(what引导宾语从句并作do的宾语)
2)What you have done might do harm to other people.

名词性从句引导词
名词性从句的引导词有that、what、which、who、whoever、whom、whomever、if等。名词性从句包括宾语从句、主语从句、表语从句和同位语从句四种。
一、that
1、引导宾语从句时,that常可省略,但如果主句后跟有并列宾语从句时,只能省略第一个that;若宾语从句前插有别的从句时,that也不能省略。例如:
He told me(that)he was all right and that he would come to see me when
he was free.他告诉我说他很好,并说在他有空时来看我。
2、that引导主语从句位于句首时不可省略.如果it作形式主语,而that从句置于句末,这时that可以省略。例如:
That he has lost his work is not true.他丢了工作不是真的。
=It is not true(that)he has lost his work.
二、引导同位语从句时,切不可错用which。例如:
Word has come that some American guests will come to visit our school next
week.有消息说下周将有一些美国客人来我校参观。
which表示特定事物中的"哪一个(些)",一般情况下在从句中充当定语,后接名词,在一定的语境中,它所修饰的名词可以省略,whichever是它的强语势"无论哪一个(些)"。例如:
I believe what (whatever) he says. 我相信他说的(不管他说什么我都相信)。
I will give her which (whichever) book she likes on the shelf. 这个书架上的(任何一本)书,只要她喜欢,我都会给她。
三、 what
1. what除引导名词性从句外,还在从句中作成分,意为“所……的(东西)”,在含义上等于“名词+that”

(which或that在定从中作主语,where不可⽤主语,故不可⽤)

名词性从句,是指性质相当于名次的从句,包括宾语从句、主语从句等。名词性从句是学习英语的难点也是高考考查的重点。卓越教育小编整理了相关资料,以供参考:
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。从高考的考查的实际情况来看,名词性从句考得最多的是宾语从句,其次是主语从句,再次是表语从句,而同位语从句则很少考查。
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:

一、 了解名词性从句与定语从句引导词的类别
1. 名词性从句的引导词分为三类:连词、连接代词和连接副词。
连词只在主句和从句间起连接作用,而不在从句中充当成分,包括that,whether,if,as
if。连接代词不但起着连接主句和从句的作用,而且在从句中充当主语、宾语或表语,包括what,which,who,whom,whose(用作定语)。连接副词就是把主句和从句连接起来,并在从句中充当状语,包括when,where,why,how。
2. 定语从句引导词分为两类,即连接代词和连接副词。
定语从句的引导词是代替了被修饰词(先行词),而被修饰词在定语从句中一定有它的位置,所以,定语从句的引导词在从句中必然充当成分,连接代词在定语从句中作主语、宾语、表语,包括which,who,whom,that,as。连接副词在从句中作状语,包括when,where,why。
二、 名词性从句与定语从句引导词的不同
1. what是名词性从句的引导词,它不能引导定语从句。
同学们往往忽视这点,在作文中经常出现这样的句子:“In that way, we can do something
what we are interested in.”“All what he needs is more time.”很显然,他们没有弄清楚what只能引导名词性从句,而在句中用它引导了定语从句,这是名词性从句与定语从句引导词误用的典型例子。
2. that在名词性从句和定语从句中的地位及作用不同。
(1)在名词性从句中,that只是个连词,只起到连接主从句的作用,在从句中不充当成分,而且在引导宾语从句时经常可以省略。

名词性从句的引导词that
(要点精讲)
that除了作代词,还可以作从属连词,引导名词性从句。
一、that引导宾语从句
1.that的省略问题
that引导宾语从句,有时候可以省略,有时候不可以省略,分为以下两种情况。
(1)可以省略
that引导的宾语从句用来陈述事实,that本身无词义,在从句中不作任何成分,在口语中常常省略。如:

I think (that) he is busy. 我认为他很忙。
He said (that) he would come to the party. 他说他会来参加晚会。
(2)不可以省略
①从句的主语是that时,that不可省略。如:
We know that that is an interesting story. 我们知道那是一个有趣的故事。
②that引导的宾语从句中若再有复合句时,that不能省略。如:
I think that if you have lost the library book, you must pay for it.
我认为如果你已把图书馆的藏书丢了,你就必须赔偿。
(that宾语从句中还有一个if引导的条件状语从句)
③主、从句之间有插入语时,that不能省略。如:
He said, in his opinion, that it was too early for middle school students to carry cell-phones.
他说,在他看来,初中生带手机太早了。(in his opinion是插入语)
It says, on the card, that it is made in China.
按照卡片上说的,它是中国制造的。(on the card是插入语)
④当两个或多个宾语从句由并列连词连接时,除第一个从句中that可以省略外,其它从句中的that不能省略。如:
