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。
5. whoever(=anyone who)意为“凡是……的人”,它的宾格形式是whomever (但在口语中常用whoever代替whomever)。
6. whose意为“谁的”,在从句中作定语。
7. what意为“什么”;whatever(=anything+that)意为“凡是……的物”。
what 和whatever都可在从句中作主语、表语、宾语。

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。
我在这里整理了相关学问,快来学习学习吧!英语语法:名词性从句主语从句宾语从句表语从句同位语从句作及物动词宾语作介词宾语that一般不省略可以省略一般不省略一般不省略一般不省略Whether/if〔是否〕放于句首时只用whether用whether/if均可,但有区分只用whether只用whether只用whether 特殊疑问词留意语序要用陈述语序名词性关系从句留意语序要用陈述语序一、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。
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。

例如:- I know that he is a good student.- She asked me if/whether I had finished my homework.- He told her (that) he loved her.3.表语从句表语从句在句中充当表语的作用。
表语从句通常以that引导,也可以用whether或if 引导。

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
D.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。
____ you have seen both fighters, ____ will win?
A. Since; do you think who B. As; who you think
C. When; whoever D. Since; who do you think
解析:根据上面的讲解,不难知道答案是D。其中do you think是插入成分,其余部分是宾语从句,作think的宾语;由于引导词在从句中作主语,所以要用主格who(不用whom)。
-I drove to Zhuhai for the air show last week.
-Is that ____ you had a few days off?
A. why B. when C. that D. where
解析:答案是A,why引导的从句作表语,同时why在从句中作原因状语。这里之所以选why,而不是when或 where等,唯一的依据便是句子的逻辑含义,及语境。
whatever,whoever,whichever引导名词性从句
一、基本用法概说英语中的-ever 词主要包括 whatever, whoever, whichever, whenever, wherever, however 等,其中可引导名词性从句的主要有 whatever, whoever, whichever等,其中可引导Roman'; mso-ascii-font-family: 'Times New Roman'">。这里所说的名词性从句主要指主语从句和宾语从句,它们通常不用于引导同位语从句,同时也很少用于引导表语从句。如:Whatever he said was right. 无论他说什么都是对的。(引导主语从句)I don’t believe whatever he said. 无论他说什么我都不信。(引导宾语从句)在某些特定的语境中,也可用于引导表语从句。如:

四、if, whether引导的名词从句
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
五、否 定 转 移
1) 将think, believe, suppose, expect, fancy, imagine等动词后面宾语 从句的否定词转移到主句中,即主句的谓语动词用否定式,而从句 的谓语动词用肯定式。
I don't think I know you. 我想我并不认识你。 I don' t believe he will come. 我相信他不回来。 注意:若谓语动词为hope, 宾语从句中的否定词不能转移。 I hope you weren't ill. 我想你没有生病吧。 2) 将seem, appear 等后的从句的否定转移到前面。

如:Whether he will be able to come remains a question. 他是否来还是问题。
That China is a great socialist country is well known. 众所周知,中国是一个伟大的社会主义国家。
注:为避免头重脚轻,使句子平衡,常用it作形式主语,而将主语从句后置。

如:What he found surprised me greatly. 他的发现使我非常吃惊。
Whoever is finished may rest. 凡是做完工的人都可以休息。
(2)表语从句就是在连系动词之后作表语的从句。

It looks as if (though) it is going to snow. 天好像要下雪似的。
注意:要区分以下句式:1. that’s why+结果;that’s because+原因。
2. the reason why /for…is that…He is absent. That’s because he is ill. 他缺席,这是因为他生病了。

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。

(完整版)名词性从句
名词性从句一.概述:在句子中起名词作用的各种从句统称为名词性从句。
根据它们在句中的语法作用,这类从句又可分为主语从句、表语从句、宾语从句和同位语从句。
二.名词性从句连接词四.if, whether的区别1.引导主语从句时,如果主语从句放在句首,只能用whether不能用if引导,但是如果用it 做形式主语,而把主语从句放在句末时,也可以用if引导.2.引导宾语从句时常放在动词know, ask, care, wonder之后,if和whether均可。
少数动词,如: leave, put, discuss, doubt后的宾语从句常用whether. 。
3.在介词后面的宾语从句中,在表语从句、同位语从句中,表“是否”,只能用whether;4.whether和if都可以和or not连用,但是whether 之后可以直接跟or not,而if不可以。
I do n’t know whether or not I will stay.(只能用whether)5.在不定式前只能用whether.如:I can’t decide whether to stay. 我不能决定是否留下。
五.与“命令、要求、建议”等相关的名词性从句中通常用虚拟语气,虚拟语气的构成是“should+动词原形”或省去should,直接用动词原形。
六.名词性从句以考查引导词为主,同时考查时态,语序,与其它从句的区别以及混同虚拟语气的考查。
