名词性从句知识点

名词性从句知识点在英语语法中,名词性从句是一个重要且复杂的部分。

它在句子中起着名词的作用,包括主语从句、宾语从句、表语从句和同位语从句。

接下来,让我们逐一深入了解。

一、主语从句主语从句即在句子中充当主语的从句。

例如,“What he said is true”(他说的是真的。

)在这个句子中,“What he said”就是主语从句。

引导主语从句的连接词主要有三类:1、从属连词:that、whetherThat he will come is certain (他会来是肯定的。

)这里的“that”在从句中不充当成分,只起引导作用。

Whether she will go there is not decided (她是否会去那里还没决定。

)“whether”表示“是否”。

2、连接代词:what、who、which、whose、whatever、whichever、whoever 等What you need is more practice (你需要的是更多的练习。

)“what”在从句中充当宾语。

3、连接副词:when、where、why、how 等When the meeting will be held has not been announced (会议何时举行还未宣布。

)需要注意的是,主语从句后置时,常用 it 作形式主语,而将真正的主语从句放在后面。

例如:It is unknown whether he will come (他是否会来还不知道。

)二、宾语从句宾语从句在句中充当宾语。

比如,“I know that he is a student”(我知道他是个学生。

)“that he is a student”就是宾语从句。

引导宾语从句的连接词与主语从句类似:1、从属连词:that(在口语或非正式文体中常省略)、whether、ifHe said (that) he was busyI wonder if/whether he will come2、连接代词:what、who、which、whose、whatever、whichever、whoever 等She asked me what I was doing3、连接副词:when、where、why、how 等Could you tell me how I can get there?宾语从句的时态要根据主句的时态来变化。

名词性从句语法总结(必备4篇)

1.宾语从句,是名词性从句的一种。

在主从复合句中充当宾语,位于及物动词、介词或复合谓语之后的从句称为宾语从句。

宾语从句分为三类:动词的宾语从句,介词的宾语从句和形容词的宾语从句。

2.宾语从句的引导词有三种:(1)以that引导的宾语从句:that引导的宾语从句一般都是由陈述句充当,引导词that没有实际意义,不在从句中作任何成分,that可以省略,而且从句成分齐全,句意完整。

Do you think (that) it will rain? 你认为天会下雨吗?He said (that) he could come on time. 他说他会准时来的。

(2)以whether或if引导的宾语从句: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句转化而来的,变成从句后,语序由原来的倒装语序变成陈述语序。

whether和if意为“是否”。

Let us know whether / if you can finish the work before Friday.请让我们知道你是否能在星期五以前把工作做完。

I don’t care whether you like the story or not.我不在乎你是否喜欢这个故事。

(3)特殊疑问词what/ when/ where/ who等引导的宾语从句:此类宾语从句原来是特殊疑问句,变成宾语从句后要用陈述语序,由wh-开头的疑问词引导。

包括who, whom, whose, what, which等连接代词和where, when, how,why等连接副词,这些引导词有各自的意思,在从句中要作相应的成分,不能省略。

例如:Could you tell me which gate we have to go to?请问我们得走哪个门?He didn’t tell me how long he would stay here.他没有告诉我他要在这里呆多长时间。

名词性从句知识点总结

名词性从句(一)围绕名词性从句的连接词1、连接代词:w h o,w h o s e,w h o m,w h a t,w h i c h。

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:w h e n,w h e r e,w h y,h o w。

注重:1、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w h e t h e r和i f(是否),a s i f(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,w h e t h e r、i f和a s i f都用不上时,才用t h a t 作连接词(t h a t本身无任何含义)。

2、不可省略的连词:(1)介词后的连词(2)围绕主语从句和同位语从句的连词不可省略。

T h a t s h e w a s c h o s e n m a d e u s v e r y h a p p y.W e h e a r d t h e n e w s t h a t o u r t e a m h a d w o n.(二)主语从句1、主语从句在复合句作主语。

(完整版)高中英语语法总结-名词性从句

名词性从句在句子中起名词作用的句子叫名词性从句(Noun Clauses). 名词性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.第一节知识点讲解顾名思义,主语从句在句子中作主语。

有时本身出现在主语的位置上,也有时出于句子结构的考虑退到句子的尾部,前面用形式主语it代替。

从句作主语时,谓语动词一般为单数形式。

如:What I saw was beyond any verbal description。

That his hair was turning grey worried him a bit。

Why the company denied the contract is still unknown。

When and where the government will build a city square is under discussion.It is pretty annoying that a small part of the machine is missing。

It remains to be seen whether the new novel will be well received。

Tips:主语从句的that绝对不能省去。

因为句子是不能做主语的,故用that引导.若去掉则没有了主语,而宾语从句的that可省。

主语从句:That he is right is known to all of us.宾语从句:We all know (that) he is right.1. It 作形式主语和it引导强调句的比较It 作形式主语代替主语从句,主要是为了平衡句子结构,主语从句的连接词没有变化。

而it引导的强调句则是对句子某一部分进行强调,无论强调的是什么成分,都可用连词that.被强调部分指人时也可用who/whom。

【英语】名词性从句知识点总结经典1一、名词性从句1.________ manners are very important in every country is known to all,but the trouble is that different countries have different ideas about ________ good manners are.A. That; whatB. That; thatC. What; thatD. What; what【答案】 A【解析】【分析】句意:众说周知,礼貌在每一个国家中都是非常重要的,但是麻烦是,不同的国家对于什么是良好的礼貌有着不同的认识。

逗号前有两个谓语动词,一个是are,一个是is known,故是两句话,需填连词连接这两句话,根据句意可知,前面是主语从句,故填that,此处的that,只起连接作用不作任何成分。

about是介词,其后是个句子故应填连词把这两句话连接起来,所缺词作are的表语,故填what。

因此选A。

【点评】考查名词性从句,本题涉及that引导的主语从句和what引导的宾语从句。

2.Some people believe _______ has happened before or is happening now will repeat itself in the future.A. whateverB. wheneverC. whereverD. no matter what【答案】 A【解析】【分析】句意:一些人认为之前发生的或现在正在发生的任何事情在将来都会重复发生。

Whatever has happened before or is happening now是一个主语从句,whatever既引导起这个主语从句,也在句中做主语。

BC项都属于副词的性质,都不能做主语,通常只能做状语;no matter what只能用来引导状语从句,故选A。

【点评】考查名词性从句,本题涉及"特殊疑问词+ever"引导的主语从句。

3.It________that the road will be closed tomorrow for repairs.A. was announcedB. has been announcedC. had been announcedD. would be announced【答案】 B【解析】【分析】本题考查动词的时态和语态。

题干句子中that到句子结束是宾语从句,且从句动词用“will+动词原形”表示将来,由此推断出空白处谓语动词应用现在的某种时态,在所给四个选项中,只有B项正确。

【点评】考查现在完成时的被动语态,其结构是have/has +been +done。

需要注意宾语从句的时态。

主句用现在时,从句所需的任何时态。

4.Has it been announced ______?A. when are the planes to take offB. that are the planes to take offC. where are the planes to take offD. when the planes are to take off【答案】 D【解析】【分析】句意: 飞机什么时候起飞已经宣布了吗?此处是when引导的主语从句,且要用陈述句语序,故选D。

【点评】考查名词性从句,it作形式主语,关系副词when引导的从句作真正的主语。

5.In the past decade, our education system too much on grades. However, grades have a direct connection with future success is still a question.A. focused; whetherB. focused; ifC. has focused; whetherD. has focused; if【答案】 C【解析】【分析】考查时态和主语从句。

根据In the past decade,在最近的几十年里,可知句子用现在完成时态,our education system是句子的主语,单数形式,所以第一空填has focused;第二空是主语从句做主语,if是否,不能引导主语从句,所以第二空填whether。

故选C。

【点评】主语从句主要有三类:1)(1)由连词that引导的主语从句:引导词that无含义,在句中不做成分,不可以省。

例如:That you will win the medal seems unlikely.你想获得奖牌看起来是不可能的。

(2)用连词whether 引导的主语从句:whether有含义(是否),在句中不做成分,不可以省。

例如:Whether she is coming or not doesn't matter too much.她来不来都无关紧要。

注意:if不能引导主语从句。

2)用连接代词引导的主语从句(在由连接代词who, whose, whom, which, what, whoever, whomever, whichever, whatever引导的名词性从句中,其连接代词在句中起名词性作用,担当一定成分).例如:What you need is more practice.你所需要的是更多的训练。

3)用连接副词when, where, why, how引导的名词性从句(其连接副词有含义,在句中作状语。

)例如:Where we should leave it is a problem.6.--- made her ashamed of herself?--- the lowest mark in her class.A. What; Because she gotB. Was it what; GettingC. What was it that; That she gotD. What was it that; Get【答案】 C【解析】【分析】句意:——是什么让她对她自己感到羞愧?——是她获得了她班上的最低分让她惭愧。

A中的what是句子的主语,但是because引导的从句不作主语,是原因状语从句,故排除;B的第一空是错误形式,故排除;C、D两项的第一个选项是一样的,说明第一个题干是一个强调句型,特殊疑问句下的强调句型,有what引导;第二个空是对what的回答,因为what是上一句的主语,That she got the lowest mark in her class是从句,可以作主语;而D项的get是动词原形,不能作主语,故答案为C。

【点评】考查强调句型的使用和对特殊疑问句的回答,注意问什么回答什么,也就是说疑问词what是句子的主语,回答的内容也需要在句子中能作主语。

7.____ he will offer us enough help doesn't matter a lot to our success.A. IfB. WhetherC. BeforeD. How【答案】 B【解析】【分析】句意:他是否提供帮助对于我们的成功没有什么关系。

If不可以引导主语从句,故选B。

【点评】考查名词性从句,本题涉及whether引导的主语从句的应用。

8.—Tell me something about your adventure in the rainforest, please.— We lost our way in the forest and ___ made matters worse was ___ night began to fall.A. what; thatB. it; thatC. it; becauseD. what; because【答案】 A【解析】【分析】考查名词性从句的连接词。

第一空what作主语从句的主语;第二空为表语从句的that。

9.They lost their way in the forest, and ___ made matters worse was that night began to fall.A. itB. whichC. thatD. what【答案】 D【解析】【分析】本题中含有一个主语从句what made matters worse,其中的what引导起这个主语从句,同时在主语从句中做主语。

AC两项不能引导主语从句,which在引导名词性从句的时候总是含有疑问的语义,而本句中并没有疑问的语义。

句意:他们在森林里迷路了,情况更糟糕的是天又黑了。

故D正确。

10._______ you don't like him is none of my business.A. WhatB. WhoC. ThatD. Whether【答案】 C【解析】【分析】句意:你不喜欢他,跟我没有什么关系。

you don't like him为主语从句,其内容已经是完整的,所以用that,且引导主语从句的that不能省略。

11.They lost their way in the forest, and ________ made matters worse was that night began to fall.A. thatB. itC. whatD. which【答案】 C【解析】【分析】句意:他们在森林里迷路了,更糟糕的是天开始黑了。

根据连词and可知,本句需要一个引导主语从句的连接词,该词同时还要能在从句里充当主语。

that不能在句中作成分;it不能引导主语从句;which意为“哪一个”,不符合本句语境。

排除A、B、D三项。

故选C。

【点评】考查名词性从句,本题涉及what引导的主语从句的应用。

12._______ is troubling me is ______ I don't understand ________ he saidA. What; that; whatB. What; what; whatC. That; that; whatD. Why; that; which 【答案】 A【解析】【分析】句意:我烦恼的是我不明白他说的话。

第一空是主语从句,从句中缺主语,要用What;第二空是表语从句,从句不缺成分,所以要填that;第三空是宾语从句,从句中的动词understand缺宾语,要填what。

故选A。

【点评】考查名词性从句,本题涉及主语从句,表语从句和宾语从句的应用。

13.________ his failure lies is expected ________ clear to us.A. What… to makeB. How… madeC. Where… to be madeD. Why… making【答案】C【解析】【分析】句意:他的失败之处有可能被我们弄清楚。
