名词性的引导词和定语从句引导词的区别 需要详细
名词性的引导词和定语从句引导词的区别 需要详细
1. 定语从句
引导词:① that, which, who, whom, whose, as ② when, where, why 2. 名词性从句 引导词:① that ② whether, if
③ 疑问词 (what, which, who, whom, whose, when, where, why, how等 ) ④ wh- ever *特别注意:
①定语从句的任一引导词均在定语从句中作成分。
②名词性从句的引导词中that 和whether/if 是不作成分的;但是疑问词和wh-ever 在从句中要作成分。
非限定性定语从句引导词和定语从句的引导词有什么区别
非限制性定语从句不能用that引导。
1.非限制性定语从句 从句部分用逗号隔开,一般放在主语后面,修饰主语,或对其解释说明;去掉从句部分,往往意思不够明确,但对整个句子结构没有影响.
The house, which we bought last month, is very nice.
2.当先行词是专有名词或物主代词和指示代词所修饰时,其后的定语从句通常是非限制性的。
Charles Smith, who was my former teacher, retired last year. 查理·史密斯去年退休了,他曾经是我的老师。
3.非限制性定语从句还能将整个主句作为先行词, 对其进行修饰, 这时从句谓语动词要用第三人称单数。
He seems not to have grasped what I meant, which greatly upsets me. 他似乎没抓住我的意思,这使我心烦。
引导定语从句的引导词有:
关联词:
⑴关系代词(6个):
①who 谁(主语)
②whom 谁(宾语)
③whose 谁的(定语)
④which 哪个(主语,宾语)
⑤that (主语,宾语)
⑥as 像~(主语,宾语)
⑵关系副词(3个):
①when ~时候
②where 哪里
③why 为什么

定语从句引导词what和that的区别,麻烦详细一点
定语从句引导词即连词中没有what. 有that,who, which,whose,whom,where 等。
1当先行词为人时用who或that . 如:He is the man that /who likes playing basketball.
2当先行词为物时用which 或that. 如:The book which /that I bought yesteday is very interesting.
总之,what 引导的是宾语从句而不是定语从句。如:I don't know what I should do next.
英语中的名词性从句引导词的选择
引导名词性从句的连线词可分为三类:
连线词:that, whether, if (不充当从句的任何成分)
连线代词:what, whatever, who, whoever, whom, whose, which.
连线副词: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.
whether 与 if 均为 “是否” 的意思。但在下列情况下,whether 不能被 if 所取代:
1.whether 引导主语从句(包括从句在句首的位置)应当用whether,不用if,如:
Whether it is true remains a problem.
Whether he will e, I am not sure.
2. 引导表语从句用whether,不用if,如:
The question is whether you should aept it.
3. whether可以引导从句作介词的宾语,而if 则不能,如:
I’m not interested in whether they’ll go or not.
It depends on whether we have got enough money.
4. whether可以直接跟动词不定式连用,而if 则不能,如:
I didn’t know whether to laugh or to cry.
She hasn’t decided whether to go or not.
5.引导同位语从句用whether,不用if,如:
The question whe大部分连线词引导的主语从句都可置于句末,用it充当形式主语。
It is not important who will go.
ther he’ll attend the meeting is essential.
1)由从属连词that引导的从句叫做名词性that-从句。that只起连线主句和从句的作用,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:
用 it 作形式主语的that- 从句有以下四种不同的搭配关系:
a. It + be +形容词+ that-从句
It is necessary that… 有必要……
It is important that… 重要的是……
It is obvious that… 很明显……
b. It + be + -ed 分词+ that-从句
It is believed that… 人们相信……
It is known to all that… 从所周知……
It has been decided that… 已决定……
c. It + be +名词+ that-从句
It is mon knowledge that… ……是常识
It is a surprise that… 令人惊奇的是……
It is a fact that… 事实是……
d. It +不及物动词+ that-分句
It appears that… 似乎……
It happens that… 碰巧……
It ourred to me that… 我突然想起
1)由wh-词引导的名词从句叫做名词性wh-从句。wh-词包括who, whom, whose, whoever, what, whatever, which, whichever等连线代词和where, when, how, why等连线副词。wh-从句的语法功能除了和that-从句一样外,还可充当介词宾语、宾语补语和间接宾语等,例如:
主语:How the book will sell depends on its author.
直接宾语:In one's own home one can do what one likes.
间接宾语:The will give whoever wins a prize.
表语:My question is who will take over the president.
宾语补足语:She will name him whatever she wants to.
同位语:I have no idea when he will return.
形容词宾语:I'm not sure why she refused their invitation.
介词宾语:That depends on where we shall go.
2)wh-从句作主语也常用先行词it做形式主语,而将wh-从句置于句末,例如:
It is not yet decided who will do that job.
1)yes-no型疑问从句
从属连词if, whether引导的名词从句是由一般疑问句或选择疑问转化而来的,因此也分别被称为yes-no型疑问句从句和选择型疑问从句,其功能和wh-从句的功能相同, 例如:
主语:Whether the plan is feasible remains to be proved.
宾语:Let us know whether/if you can finish the article before Friday.
表语:The point is whether we should lend him the money.
同位语:They are investigating the question whether the man is trusorthy.
形容词宾语: She's doubtful whether we shall be able to e.
介词宾语: I worry about whether he can pass the exams.
2)选择性疑问从句
选择性疑问从句由关联词if/whether…or或whethe…or not构成,如:
Please tell me whether / if they are Swedish or Danish.
I don't care whether you like the plan or not.
定语从句引导词问题修饰人时,that和who的区别
先行词指人时,关系代词既可用who,亦可用that。但关系代词在从句之中用作主语时,多用主格who。如:
Persons who are quarrelsome are despised. 好争吵者遭轻视。(除外persons,还有people,those,等皆多用who)
All who heard the story were amazed. 听到这个故事的人都感到吃惊。(代词如he,they,any,all,one等之后多用who)
I will pardon him who is honest. 我愿意宽恕他,他是诚实的。(描述性定语从句用who)
I think it is you who should prove to me. 我认为是你应该向我提出证据。(在强调结构中多用who,who在此可省去)
Who is not for us is against us. 谁不赞成我们就是反对我们。(缩合连线代词who为可代之以that)
在下列一些情况中则多用that。如:
)He was the man that the bottle fell on. 他就是瓶子落在其身上的那个人。(此处常用that作宾语指人,亦可用whom)
He is a man that is never at a loss. 他是一个从未一筹莫展的人。(that常用于泛指人)
He was watching the children and parcels that filled the car. 我望着塞满车的孩子和包裹。(兼指人与物时须用that)
Who that you have ever seen can beat him in chess? 你曾见过谁能在棋艺上打败他?(避免与先行词who重复时应用that)
That’s the same man that asked for help the day before yesterday. 这个与前天求援的是同一个人。(先行词前有指示代词same时应用that)
He is not that man that he was. 他已不是过去的他了。(that常用作表语)
I knew her father for the simplest, hardest working man that ever drew the breath of life. 我早知她的父亲是一个世上最简朴最努力工作的人。(先行词前有形容词最高阶、序数词或only等词时应用that)
希望我能帮助你解疑释惑。
名词性从句所有引导词的具体意思
名词性从句的连线词可细分为以下四种:(1)以that来引导从句;(2)以whether/if引导从句;(3)以特殊疑问词引导从句;(4)以关系代词/副词引导从句
1. 连线词 that 只起连线作用,没有任何意思,也不充当句子成分
2. 连线词whether/if也不充当句子成分,但有自己的意思,表示“是否”;
3.英语中所有用来构成特殊疑问句的特殊疑问词均可以用来引导名词性从句, 意思也和特殊疑问词中的疑问词意思相同,其中包括关系副词和关系代词
关系副词:what(什么); who(谁)); which(哪一个); whose (谁的);whoever (无论谁);whatever(无论什么); whichever(无论哪一个)
关系代词when (什么时候) where(在什么地方); wherever(无论哪里)); why(为什么)how(怎样)
4.、以关系词引导从句 用关系词引导的名词性从句又可称作名词性关系从句,因为它实际上是先行词与在其后的定语从句的结合。引导这种名词性从句的关系词有:what "……的东西、所。。。"when"...的时候"where"...的地方"
他们可以转换为:what(=the thing that), where(=the place where), when(=the time when)这样就把他们转换为定语从句,选择题时通过转换可以更好判断
定语从句,没有 what 当引导词的吗?
定语从句(Attributive Clauses)在句中做定语,修饰一个名词或代词,被修饰的名词,片语或代词即先行词。定语从句通常出现在先行词之后,由关系词(关系代词或关系副词)引出。
关系代词有:who, whom, whose, that, which等。
关系副词有:when, where, why等。
定于从句,已经清楚的指明物件,所以也就不需要用what来引导
关于定语从句引导词的一个问题,谢谢。
定语从句中只有关系代词做宾语时是可以省略的,其他情况都不行,所以你提到的几个都是不可以省略的。
名词性从句引导词分为几类?各有些什么?
名词性从句分为四类,分别为主语从句、宾语从句、表语从句以及同位语从句。那么,名词性从句引导词即是这四大从句的引导词。
引导词有:1、连线词that, if ,whether,;疑问代词who,what,which和疑问副词when,where,how,why等。
2、as,as if ,as though,because可以引导表从
3、还有连线代词whatever,whoever,whichever等;(可引导主从、宾从)
以上并非分类,因为连线词可以具体用在不同从句当中。只是相当于一个罗列,希望对你有用
