名词性从句知识点
名词性从句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、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:从属连词:that(无任何词意);whether, if(均表示“是否”表明从句内容的不确定性);as if ,as though(均表示“好像”,“似乎”)because。
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,whenever,whereever.名词性从句的分类1.主语从句作句子主语的从句叫主语从句。
主语从句通常由从属连词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。
that 在句中无词义,只起连接作用;连接代词和连接副词在句中既保留自己的疑问含义、又起连接作用,在从句中充当从句的成分。
例如:What he wants to tell us is not clear. 他要跟我们说什么,还不清楚。
Who will win the match is still unknown. 谁能赢得这场比赛还不得而知。
It is known to us how he became a writer. 我们都知道他是如何成为一名作家的。
Where the English evening will be held has not yet been announced. 英语晚会将在哪里举行,还没有宣布。
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。
高中英语高考名词性从句专项复习(知识点+易错点+练习题)
高考英语名词性从句知识点一、that 从句1、主语从句(1)that 从句作主语时,常用it 作形式主语,常见的句型有:It+be+形容词(obvious, true, natural, surprising, good, wonderful, funny, possible, likely, certain, probable, etc.)+ that从句It+be+名词词组(no wonder, an honor, a good thing, a pity, no surprise, etc.)+ that 从句It+be+过去分词(said, reported, thought, expected, decided, announced, arranged, etc.)+ that 从句(2)that可以省略,但 that 从句位于句首时,that不能省略。
2、宾语从句(1)常见的可以接 that 从句作宾语的动词有see, say, know, imagine, discover, believe, tell, show, think, consider, be sure, be afraid等。
在可以接复合宾语的动词之后,如 think, make, consider等,可以用 it 作形式宾语。
(2)That 从句一般不能充当介词宾语,偶尔可作except, in 的宾语。
3、表语从句(that不可省略)4、同位语从句连词that引导同位语从句时,应在某些抽象名词之后,如:fact, hope, desire, thought, suggestion, idea, news, problem, possibility 等,对前面的名词起补充说明的作用,that在从句中不担当任何成分,不能省略。
二、whether/if从句1、在表语从句和同位语从句中,只能用 whether 不能用 if;当主语从句放于句首时,只能用 whether 不用 if;当 it 作形式主语,主语从句放在句末时用 whether或if均可;discuss 后引导宾语从句时,必须用whether。
名词性从句知识点
复合句中具有名词性质并且可以做主语、表语、同位语或宾语的从句叫名词性从句。
因此,我们把主语从句、表语从句、同位语从句和宾语从句这四种从句统称为名词性从句。
高考热点1)怎样判断名词性从句的类别;2)连词that 和what的用法与选择3)if 与whether的区别4)同位语从句与定语从句的区别5)名词性从句必须采用的陈述语序6)it 可充当形式主语和形式宾语7)疑问词+-ever的连词和不加-ever的连词在语义上的用法和差别核心解读一1、在名词性从句中,从句都用陈述语序。
2、引导名词性从句的词叫引导词。
引导词可以分为以下几类:1)从属连词that(用于表示肯定的含义), whether, if (表示疑问),这三个词只起连接作用,不充当从句中的任何成分,除宾语从句外(that可省),这些词均不可省略。
2)连接代词有who, whom, whose, what, which, whoever, whatever, whichever等。
这些词在从句中既起连接作用,又充当从句中的成分,如主语、宾语、表语、补语,且不可省略。
3)连接副词有when, where, why, how, wherever, however等。
它们既起连词作用,本身又做从句中的状语。
3、名词性从句中的时态一致问题1)在宾语从句中,当主句是一般现在时、将来时或现在完成时,起从句的谓语根据需要用适当的时态。
当主句是一般过去时,从句用过去的某个时态,但若宾语从句表示客观真理,格言,谚语等,从句的时态仍用一般现在时。
Have you told him that when we are to leave?Teacher told us that China lies in the west of Japan.Although she was listening, she didn’t hear what he was saying because t here was so much noise.2)在主语从句、表语从句或同位语从句中,应注意主语从句中的谓语动词的时态一致性及动作发生的先后关系。

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。
有词义,在从句中担任成分,作状语。
3、连接词:t h a t,w h e t h e r,i f,a s i f。
t h a t无词义,在从句中不担任成分,有时可省略;i f(w h e t h e r),a s i f虽有词义,但在从句中不担任成分。
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。

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。

高中英语名词性从句知识点(含练习)
高中英语名词性从句知识点(含练习)基础回顾1.表语:表语用来说明主语的身份、性质、品性、特征和状态的,表语常由名词、形容词、副词、介词短语、动词的-ing、不定式、从句来充当,它常位于系动词(be, become, appear, seem,look,sound,feel,get,smell等词)之后。
如:Her job is selling computers. 此句表语为selling computers如果句子的表语也是由一个句子充当的,那么这个充当表语的句子就叫做表语从句。
2.同位语:一个名词(或其它形式)对另一个名词或代词进行解释或补充说明,这个名词(或其它形式)就是同位语。
如Mr. Smith,our new teacher,is very kind to us. 我们的新老师史密斯先生对我们很好。

that our team had won 解释news的具体内容,是同位语正文一、定义在复合句中具有名词的性质的作主语、表语、同位语、宾语的从句叫名词性从句。

That he finished writing the composition in such a short time surprised us all他在很短的时间内写完作文让我们都很惊讶 (主语从句)The trouble is that she has lost his address. 麻烦的是她把他的地址搞丢了。
(表语从句)They have no idea at all where he has gone. 他们不知道他去什么地方了。
