语法六:名词性从句
名词从句讲解

名词性从句一、定义:在句子中起名词作用的句子叫名词性从句二、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。
三、类型根据它在句中不同的语法功能,名词性从句又可分为:1.主语从句2.宾语从句3.表语从句4.同位语从句四、特点:名词性从句的特点是从句都有关联词引导,从句的语序是陈述句语序。
五、连词(1)连接词:that /Whether/if:不充当从句的任何成分(2)连接代词:Who/whoever/Whom/whomever/whose /What/whatever /Which/whichever既起连接一个句子的作用,同时在从句担当主语、宾语,表语。
(3)连接副词:Why/where/when /how:既起连接作用,又在从句中作状语六、名词性从句引导词的用法:1.that无具体意思,在从句中也不充当任何语法成分,只起连接作用2.whether意为“是否”,在从句中不充当任何语法成分;引导及物动词的宾语从句时可与if互换;引导介词的宾语从句或引导主语、表语、同位语从句时,只用whether。
3. who意为“谁”,在从句中作主语。
4. whom意为“谁”,在从句中作宾语,但在口语中常用who代替whom。

英语语法:名 词 性 从 句

英语语法:名词性从句名词性从句是在句子中起名词作用的句子。
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,名词性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。

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。
英语语法几大从句(六级)

名词性从句常见考点突破一、名词性从句的概念及分类1.顾名思义不,名词性从句就是指在句子中起名词作用的句子,功能相当于名词词组。
2.根据其在句中不同的语法功能,名词性从句可以分为主语从句、宾语从句、表语从句和同位语从句。
同位语从句起对前面的名词进一步解释说明的作用,陈述该名词的内容。
二、名词性从句的三类引导词1.连接词,包括that,whether和if。
that用来引导陈述句,whether和if引导一般疑问句(从句中的一般疑问句要用陈述句语序,而if引导的从句不能作主语)。
2.wh-关系代词,如who,whom,whose,whatever,which等,这类词由于在句中作相应的句子成分,因此一般不能省略。
3.wh-关系副词,如when,why,how,where等,该类词一般也作相应的句子成分。
三、名词性从句的四种类型1.宾语从句①在许多情况下,作为真正宾语的that从句后置,而用it作形式宾语,此时,that不可省略。
例如:You may rely on it that I shall help you.(it作为形式宾语接在rely on后,真正的宾语是that引导的宾语从句。
另外,大多数介词不能直接跟that从句作宾语,所以此处需要it作形式宾语。
)②宾语从句分为三类:动词宾语从句、介词宾语从句和形容词宾语从句。
动词宾语从句指的是跟在动词之后且充当其宾语的从句;介词宾语从句指的是跟在一个介词之后充当其宾语的从句;同样,形容词宾语从句指的是跟在某些形容词后面,可理解为该形容词宾语的从句。
例如:I doubt whether he will come.(动词宾语从句)I'm curious as to what he will do.(介词宾语从句)I'm convinced that she is an honest girl.(形容词宾语从句)2.同位语从句①同位语从句就是跟在名词后面,表达具体内容、起解释说明作用的从句。
高中英语语法:名词性从句知识汇总

高中英语语法:名词性从句知识汇总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。
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。
当名词性从句要采用陈述句语序。
由一个含疑问意义的连词引起时,必须将该连词放在名词性从句的开头,且该从句语序不能倒装。
一、引导名词性从句的关联词引导名词性从句的关联词大致相同,它们分别是:连词:that, whether, if;关系代词:who, what, which , whom, whose, whatever, whoever, whomever, whichever;关系副词:when, where, how, why, however, whenever, wherever。
引导从句时一般不用逗号和主句分开。
连词that在从句中不作成分,不含疑问意义;而wh-连词在从句中作成分,且含有疑问意义;或what/where从句相当于一个名词后加一个定语从句。
It worried her a bit that her hair was turning grey.她的头发在变白令她有点担忧。
(that在从句中只起引导词作用,不作成分)What caused the accident is still a complete mystery.事故发生的原因仍然是个不解之谜。
(What在从句中作主语)2、that与whether引导名词性从句的区别。
(1)动词doubt表示“怀疑、不知道”解时,肯定句接whether引导的宾语从句;否定句don’t doubt和疑问句Do you doubt要接that引导的从句。
I don’t doubt that he will come soon.我不怀疑他不久会来。
(此处不用whether)Can you doubt that he will win?你怀疑他会赢吗?(此处不用whether)比较:doubt表示“不信”解时,表示强烈的不相信时,在陈述句中可接that从句。

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。
