英语名词性从句知识点复习一、概述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。

It is a fact that English is being accepted as an international language.事实上英语作为国际语言正为世人所接受。

(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。

(同位语从句)Do you remember how he came ? 你记得他怎么来的么?(宾语从句)二、语序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。

What we can't get seems better than what we have. 我们得不到的似乎比我们所拥有的要好。

The photographs will show you what our village looks like .这些照片将向你展示我们村庄的面貌。

Can you make sure where Alice has put the gold ring ?你能肯定爱丽丝放金戒指的地方吗?No one can be sure what man will look like in a million years .没有人肯定一百万年后人类会是什么样子。

He asked how much I paid for the violin . 他问我花了多少钱买这个小提琴。

三、时态的呼应名词性从句特别是宾语从句中谓语动词的时态要与主句中谓语动词时态要相呼应,主要有下列几种情况:(1)如果主句中的谓语动词是一般现在时态,从句的谓语动词的时态不受主句谓语动词时态的制约。

(完整版)同位语从句用法详解

(完整版)同位语从句用法详解

同位语从句(1)概念在复合句中充当同位语的名词性从句称为同位语从句。

一个名词(或其它形式)对另一个名词或代词进行修饰,限定或说明,这个名词(或其它形式)就是同位语。

同位语与被它限定的词的格要一致,并常常紧挨在一起。

(2)同位语1. 名词作同位语Mr. Wang, my child’s teacher, will be visiting us on Tuesday.王先生,我孩子的老师,星期二要来看我们。

2. 短语作同位语I, the oldest girl in the family, always had to care for the other children.我,作为家里最大的女孩,老得照料家中的其他孩子。

3. 直接引语作同位语But now the question comes to their minds, “Did she die young because she was a clone?”但是现在他们不得不思考这样的问题:“多利早死是因为它是一只克隆羊吗?”4. 句子作同位语The girls were surprised at the fact that ocean ships can sail up the Great lakes.巨大的海轮可以开到五大湖,让表姐妹俩感到吃惊。

(3)同位语从句用法1位置:同位语从句一般跟在某些名词后面,用以说明该名词表示的具体内容。

I heard the news that our team had won.我听到了我们队获胜的消息。

①可以跟同位语从句的抽象名词通常有news,idea,fact,promise,question,doubt,thought,hope,message,suggestion,words(消息),possibility等。

(承诺信息主意是事实;疑问想法与问题;希望消息建议是潜力。

)I’ve come from Mr. Wang with a message that he won’t be able to see you this afternoon.我从王先生那里来,他让我告诉你他今天下午不能来看你了。

(完整word)各类从句讲解

各类从句详解英语从句可以分为名词性从句、定语从句和状语从句三大类:下面我们逐一进行说明:一、名词性从句(主语从句、表语从句、宾语从句、同位语从句)主语从句、表语从句、宾语从句和同位语从句在复合句中的充当的成分和其名称相同,分别作主句的主语、表语、宾语和同位语。

上述这四种从句均被称为名词性从句.所有的名词性从句均不能用逗号分开,并且它们都用相同的关联词,关联词如下:①主从连词:that (无意义), whether (是否), if (是否)(在句子中不充当任何成分)②连接代词:who (谁), whom (谁), whose (谁的), what (什么), which (哪一个)③连接副词:when (什么时候), where (什么地方), how (怎样), why (为什么)主从连词只起连接作用,连接代词和连接副词除了起连接作用外,还充当从句某一个成分。

另外,可以用whatever, whichever, whoever, who(m)ever等连接代词引导名词性从句,来加强语气.下面分别对各种名词性从句进行介绍(一)主语从句(subject clause)在主句中用作主语的主谓结构称之为主语从句。

例如:That he will come to the discussion is certain.他来参加讨论是确定的。

That the moon moves round the earth is well known to all of us。

月球绕地球转动,这是我们大家都熟知的。

When the meeting is to be held has not yet been decide. 会议什么时候召开还没有决定。

主语从句放在句首,句子常常显得比较笨重,因此通常可以把it放在句首,作形式主语,而将主语从句放在后面.例如上面的句子可以分别改写为:It is certain that he will come to the discussion。

英语名词性从句讲解【完整版】

1、It depends on weather if she will come back on time .
2、I asked him if he could do me a favor .
If与whether的区别:
1、If不能引导放于句首的主语从句,而whether可以。 2、引导表语从句用whether,不用if。 3、引导同位语从句用whether,不用if。 4、whether可以引导从句作介词的宾语,不用if 。 5、whether or not 连在一起可以,但if不可以。而 “whether-----or not = if -----or not”
同位语从句:
定义:在复合句中充当同位语的句子。 同位语从句用来对其前面的抽象名词进行解释说明,被解释说明的词和 同位语在逻辑上是主表关系。 同位语常见名词:fact, suggestion, advice, idea, decision, news, thought, hope, belief, truth, doubt, promise, possibility, truth, warning, message, reason, report, question,explanation, wish, problem等。 常见的连接词:that, whether, what, who, how, when, where等。 用法: The thought that I want to buy my mother a birthday gift makes me excited.that 引导的同位语从句,解释说明 thought,从句不缺成 分 There is some doubt whether he will come. whether 引导同位语从句,if 不能引导同位语从句 we haven’t made the decision where we are going to spend our vacation. 有时同位语从句可以不紧跟解释说明的名词后面。 The news is surprising that he won the match.

适用文档名词性从句解说在复合句中起名作用的从句叫做名性从句。

它包含主从句、从句、表从句和同位从句。

名性从句是中学段的一个重要法目,在年的高考取几乎都波及到,而且每年的命各有化。

解析届高考名性从句考的焦点主要有以下六个方面1. 考名性从句的序2. 考引 that 与 what 的区3. 考 it 在名性从句中作形式主或形式的用法4. 考 whether 与 if 的区5. 考名性从句中的疑+ever 引的名性从句与no matter+ 疑引的状从句的区6.考名性从句的虚气法重点解析一、名性从句主从句、表从句、从句、同位从句,在整个句子中所起的作用,相当于一个名。

所以,四种从句通称名性从句。

引名性从句的接可分三:接: that, whether, if(不充任从句的任何成分)接代: what, whatever, who, whoever, whom, whose, which.接副: when, where, how, why1.主从句作句子主的从句叫主从句。

主从句往常由附属that ,whether ,if和接代what ,who,which ,whatever , whoever 以及接副 how, when, where, why 等引。

that 在句中无,只起接作用;接代和接副在句中既保存自己的疑含、又起接作用,在从句中充任从句的成分。

比如:What he wants to tell us is not clear.他要跟我什么,不清楚。

It is known to us how he became a writer.我都知道他是如何成一名作家的。

Where the English evening will be held has not yet been announced.英晚会将在哪里行,没有宣告。

有防止句子重脚,常用形式主it取代主从句作形式主放于句首,而把主从句置于句末。

主从句后的一般用数形式。

同位语从句属于名词性从句

同位语从句属‎于名词性从句‎,大多由从属连‎词that引‎导,常常跟在fa‎c t, idea, opinio‎n, news, hope, belief‎等名词后面。

同位语从句一‎般用来解释或‎说明这些名词‎的具体含义或‎内容,在逻辑上表现‎为同位关系。

完整版)名词性从句用法归纳

完整版)名词性从句用法归纳名词性从句是指在句子中作名词角色的句子,可以充当主语、宾语、表语、同位语、介词宾语等。

名词性从句包括主语从句、宾语从句、表语从句和同位语从句。

引导名词性从句的连接词可以分为三类。

第一类是从属连词,包括that、whether和if。

在宾语从句或表语从句中,that 有时可以省略。

第二类是连接代词,包括what、who、which 等。

这些代词在从句中做成分,不可以省略。

第三类是连接副词,如when、where、how等,也不可以省略。

在一些情况下,that可以省略,如定语从句中做宾语、引导宾语从句或表语从句时。

但在定语从句中做主语、由that引导同位语从句时,以及宾语从句中真正的that不可以省略的情况下,that不能省略。

主语从句是指作句子主语的从句。

主语从句通常由从属连词that、whether等,连接代词what、who、which等,以及连接副词how、when、where等引导。

2、连接词的使用:连接词在句子中起到连接的作用,其中that在句子中没有实际的意义,只是起到连接从句和主句的作用。

而连接代词和连接副词则在句子中既保留了自己的疑问含义,又起到连接从句和主句的作用,同时在从句中充当从句的成分。

例如,whom和who指人,what指物,而XXX和whoever则表示泛指意义。

举个例子,What he wants to tell us is not clear.表示他想告诉我们什么并不清楚。

另外,为了避免句子头重脚轻的情况,有时我们会用形式主语it代替主语从句,并将主语从句放在句末。

这种情况下,主语从句后的谓语动词一般使用单数形式。

常用的句型有:(1)It + be +名词+ that从句,如It is a fact that(事实是);(2)It + be +动词的过去分词+ that从句,如It is said that(据说);(3)It +不及物动词(vi)+ that从句,如It seems that (似乎);(4)It + be +形容词+ that从句,如It is naturalthat(很自然)。

同位语从句属于名词性从句,大多由从属连词that引导,常常跟在fact, idea, opinion, news, hope, belief等名词后面。

同位语从句一般用来解释或说明这些名词的具体含义或内容,在逻辑上表现为同位关系。

例如:They are familiar with the opinion that all matter consists of atoms.他们很熟悉这一观点,所有的物质都是由原子构成的。

1、从先行词来看同位语从句与名词之间在逻辑上是"主语+be+表语"的关系。

该名词是需要做特殊说明的抽象名词。

例如:They were delighted at the news that their team had won.当听到他们的球队赢了的消息时,他们欣喜若狂。

2、从引导词来看引导词that在同位语从句中是连词,只起连接作用,无具体词义,that不可省略;that在定语从句中是关系代词,它在从句中充当一定成分---主语或宾语,有具体词意,作宾语时还可以省略。

试比较:The factory(that)we visited yesterday is a chemical one.我们昨天参观的那家工厂是化工厂。

(that在从句中作宾语,所以此句是宾语从句)The news that he will leave for Shanghai is true.他将要去上海的消息是真的。

(that只起连接从句的作用,所以此句是同谓语从句)同位语从句讲解及练习一、理解同位语从句的含义,把握同位语从句的实质在主从复合句中作同位语的从句称为同位语从句。

同位语从句一般用t hat, whether,what, which, who, when, where, why, how 等词引导,常放在fact, news, idea, truth, hope, problem, information, wish,promise, an swer, evidence, report, explanation, suggestion, conclusion等抽象名词后面,说明该名词的具体内容。

换言之,同位语从句和所修饰的名词在内容上为同一关系,对其内容作进一步说明。

例:The news that they had won the game soon spread over the whol e school.他们比赛获胜的消息很快传遍了整个学校。

析:they had won the game说明The news的全部内容,因此该句为同位语从句。

二、正确运用同位语从句的引导词,准确把握同位语从句1.如同位语从句意义完整,应用that引导同位语从句。

(即that 不充当任何成分,只起连接作用,不可省略)例:The general gave the order that the soldiers should cross the river at once.将军下达了战士们立即过河的命令。

析:the soldiers should cross the river at once是the order的全部内容,且意义完整,因此应用that引导同位语从句。

2.如同位语从句意义不完整,需增加"是否"的含义,应用whether引导同位语从句。

(if不能引导同位语从句)例:We'll discuss the problem whether the sports meeting will be held on time.我们将讨论运动会是否会如期举行的问题。

析:the sports meeting will be held on time意义不完整,应加"是否"的含义才能表达the problem的全部内容,因此应用whether引导同位语从句。

3.如同位语从句意义不完整,需增加"什么时候"、"什么地点"、"什么方式"等含义,应用when, where, how等词引导同位语从句。

例1:I have no idea when he will be back.析:he will be back意义不完整,应加"什么时候"的含义才能表达i dea的全部内容,因此应用when引导同位语从句。

例2:I have no impression how he went home, perhaps by bike.析:he went home意义不完整,应加"如何"的含义才能表达impression的全部内容,因此应用how引导同位语从句。

4.当主句的谓语较短,而同位语从句较长时,同位语从句常后置。

如:The thought came to him that maybe the enemy had fled the cit y.三、把握同位语从句和定语从句的区别,明确同位语从句和相似从句的界限同位语从句和定语从句相似,都放在某一名词或代词后面,但同位语从句不同于定语从句。

同位语从句对名词加以补充说明,是名词全部内容的体现,且名词和同位语从句的引导词均不在从句中作成分;定语从句说明先行词的性质与特征,与先行词是修饰与被修饰的关系,且名词和定语从句的引导词均在从句中作成分。

区分时可以在先行词与与从句之间加一个系动词be,使之构成一个新句子,如果句子通顺且符合逻辑,则为同位语从句,反之,则为定语从句。

如:The report that he was going to resign was false.因为the report was that he was going to resign 句意通顺,所以,th at he was going to resign 是同位语从句。

例1:1)Information has been put forward ____ more middle school gradu ates will be admitted into universities.A. whileB. thatC. whenD. as析:答案为B。

more middle school graduates will be admitted in to universities是Information的内容,且Information不在从句中作成分,所以该句为同位语从句。

应将该句区别于:2)It is said that more middle school graduates will be admitted into universities,this is the information ____ has been put forward.A. whatB. thatC. whenD. as析:答案为B。

that has been put forward为information的修饰性定语,且information在从句中作主语,所以该句为定语从句。

例2:She heard a terrible noise,____ brought her heart into her m outh.(MET91)A. itB. whichC. thisD. that析:答案为B。

分析语境含义、句子结构和句子成分可知,该句为非限制性定语从句,先行词为a terrible noise,且它在从句中作主语。

应将该句区别于:I can't stand the terrible noise ____ she is crying loudly.A. itB. whichC. thisD. that析:答案为D。

she is crying loudly是the terrible noise的内容,且t he terrible noise不在从句中作成分,所以该句为同位语从句。

(同位语从句)We are not looking into the question whether he is worth trustin g.(同位语从句)Word came that he had been abroad. (同位语从句)Our team has won the game, which made us very happy.我们的队赢了,这让我们很高兴?(定语从句)The doctor whom you are looking for is in the room.你找的那位医生在房间里面?(定语从句)His mother did all she could to help him with his study.他妈妈尽她的最大努力帮助他的学习?(定语从句,代词all作先行词?)2. 从性质上区别定语从句是从句对其先行词的修饰或限制,属于形容词性从句的范畴;而同位语从句是从句对前面抽象名词的进一步的说明和解释,属于名词性从句的范畴。
