同位语从句讲解及练习

同位语从句

◆◆◆辨认同位语从句

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。

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,星期二要来瞧我们。

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,老得照料家中的其她孩子。

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?”但就是现在她们不得不思考这样的问题:“多利早死就是因为它就是一只克隆羊不？”

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。

◆◆◆同位语从句用法

一、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。(承诺信息主意就是事实;疑问想法与问题;希望消息建议就是潜力。) 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,她让我告诉您她今天下午不能来瞧您了。

②在某些名词表“建议,命令,要求等”(如demand, wish, suggestion, resolution等)后面的同位语从句要用虚拟语气 (即should+动词原形;should可省)

There was a suggestion that Brown should be dropped from the team、有一项建议就是布朗应该离队。

③同位语从句前名词的数:同位语从句前的名词通常用单数形式,并且往往带有限定词(word除外)加以修饰。

Where did you get the idea that I could not come？您在哪儿听说我不能来？

二、英语中引导同位语从句的词通有连词that,whether,连接代词what,who。连接副词how, when, where等。(注:if, which 不能引导同位语从句。)

1、连词that引导同位语从句(注:引导同位语从句的that不能省略)

The idea that you can do this work well without thinking is quite wrong、您认为不动脑筋就能做好这件工作的想法就是完全错误的。(作idea的同位语)

【注意】引导同位语从句的连词that通常不省略,但在非正式文体中也可以省去。

He grabbed his suitcase and gave the impression he was boarding the Tokyo plane、她拿起了手提箱,给人的印象就是她要登上飞往东京的飞机了。

2、连词whether引导同位语从句(注:if不能引导同位语从句)

The question whether we should call in a specialist was answered by the family doctor、我们就是否请专家由家庭医生来定。

He must answer the question whether he agrees to it or not、她必须回答她就是否同意这样一个问题。

3、其它引导词引导的同位语从句

A、连接代词what, who, whom, whose引导同位语从句

1)、I have no idea what size shoes she wears、我不知道她穿几号的鞋。(what作定语)

2)、The question who will take his place is still not clear、(who作主语)

B、连接副词when, where, how, why 引导同位语从句

We haven’t yet settled the question where we are going to spend our summer vacation、到哪儿去度暑假,这个问题我们还没有决定。

l have no idea When he will be back.我不知道她什么时候回来。

My question how I shall get in touch with him has not been answered、

三、有时同位语从句可以不紧跟在说明的名词后面,而被别的词隔开。在语法上叫做分隔式同位语从句。

The thought came to him that maybe the enemy had fled the city.

她突然想起可能敌人已经逃出城了。

Several years later,word came that Napoleon himself was coming to inspect them. 几年以后,有消息传来说拿破仑要亲自视察她们。

◆◆◆定语从句与同位语从句的区别

1、意义的不同

同位语从句就是用于说明所修饰名词的具体内容的,它与被修饰词语通常可以划等号;而定语从句就是限制所修饰名词的,它的作用就是将所修饰的名词与其她类似的东西区别开来:

We are glad at the news that he will come、听到她要来这个消息我们很高兴。(news 的内容就就是that he will come,故that引导的就是同位语从句)

We are glad at the news that he told us、听到她告诉我们的这个消息我们很高兴。(that 从句就是限制the news的内容的,即我们高兴只就是因为她告诉的这个news而不就是其她的news,故that从句为定语从句)

2、被修饰词语的区别

A.定语从句的先行词就是名词或代词;而同位语从句的先行词只能就是名词,而且仅限于idea,plan,fact,theory,promise,hope,news,doubt,truth,information,suggestion,que stion, thought,belief,conclusion等少数名词。

例如:

①The boy who is playing football is my classmate.

②Those who work hard will succeed.

③The fact that he had not said anything surprised everybody.

④The fact that you are talking about is important.

在①句中,划线部分就是定语从句,其先行词就是名词 boy,它不能用作同位语从句的先行词。

在②句中,划线部分也就是定语从句,其先行词就是代词those,代词不能用作同位语从句的先行词。

在③句中,划线部分就是同位语从句,其先行词就是名词fact,它同样可以用作定语从句的先行词,④句便就是一例。

由以上分析可见,同位语从句的先行词一定可以用作定语从句的先行词,但定语从句的先行词不一定能用作同位语从句的先行词。

B.when,where,why引导的定语从句的先行词一定分别就是表示时间、地点与原因的名词,而三者引导的同位语从句的先行词则肯定不就是表示时间、地点与原因的名词。

例如:

①I still remember the day when I first came to Beijing.

②I have no idea when she will be back.

在①句中,划线部分就是when引导的定语从句,其先行词day就是表示时间的名词;

在②句中,划线部分就是when引导的同位语从句,其先行词idea则不就是表示时间的名词。

3、引导词的不同

定语从句与同位语从句共同的引导词有四个:that,when,where,why。下面把四个引导词分成两类说明它们在两种从句中的不同用法。

A.引导词that

引导定语从句的that叫做关系代词,它除了起连接作用,还在定语从句中充当一定成分,并且在意义上代表先行词;引导同位语从句的that叫做从属连词,它只起连接作用。不能省略。

例如:

①The news that you told me yesterday was really exciting.

②We heard the news that our team had won.

在①句中,划线部分就是定语从句,that在从句中作宾语,在意义上指代先行词news。

在②句中,划线部分就是同位语从句,that没有任何意义,只起连接作用。

that引导同位语从句时,它不充当句子成分,而引导定语从句时,它作为关系代词,要么充当定语从句的主语,要么充当定语从句的宾语。如上例 that he told us中的that就充当told的宾语。

B.引导词when,where,why

引导定语从句时,它们叫做关系副词,在从句中充当状语,可以转换成"介词＋关系代词"的形式;引导同位语从句时,它们叫做连接副词,在从句中充当状语,但不能转换成"介词＋关系代词"的形式。

例如:

①I will never forget the day when I joined the army.

②We have no idea when she was born.

在①句中,划线部分就是定语从句,when在从句中作状语,它可以转换成on which的形式;

在②句中,划线部分就是同位语从句, when在从句中充当状语,但不能转换成"介词＋关系代词"的形式。

③This is the house where I lived two years ago.

④He put forward to the question where the meeting would be held.

在③句中,划线部分就是定语从句,where在从句中作状语,它可以转换成in which的形

式;

在④句中,划线部分就是同位语从句, where在从句中充当状语,但不能转换成"介词＋关系代词"的形式。

⑤This is the reason why she will not attend the meeting.

⑥The teacher had no idea why Jack was absent.

在⑤句中,划线部分就是定语从句,why在从句中作状语,它可以转换成for which的形式;在⑥句中,划线部分就是同位语从句,why在从句中充当状语,但不能转换成"介词＋关系代词"的形式。

◆◆◆同位语从句-相关语法

1、同位语从句在句中的位置

1、一般情况下同位语从句跟在某些名词(如news,idea,fact,promise,hope,message 等)的后面,用以说明该名词所表达的具体内容。

I’ve come from Mr Wang with a message that he won’t be able to see you this afternoon、我从王先生那边得知一个消息,她说她今天下午不能来瞧您了。

2、有时同位语从句可以不紧跟在它所说明的名词后,而被别的词语隔开,在语法上叫做分隔式同位语从句。

The thought came to her that maybe she had left the door open when she left home、她突然想起可能在她离开家时没把门关上。

2、同位语从句前名词的数

同位语从句前的名词通常用单数形式,并且往往带有限定词(word除外)加以修饰。

Where did you get the idea that I could not come？您在哪儿听说我不能来？

3、同位语从句的语气

在suggestion,advice,request,order等意为“建议;命令;要求”的名词后,同位语从句中的谓语动词通常用“should +动词原形”的虚拟语气结构,句中的should可以省略。 Our teacher gave us some advice how we(should)use the computer、老师给我们提出了一些如何使用电脑的建议。

4、同位语从句的先行词

同位语从句的先行词通常就是抽象名词,常见的有:idea, situation thought, fact, evidence, belief, doubt, fear, hope, question, theory, news, order, ability等等。

How did the cheats explain the fact that the Emperor didn't feel the new clothes in him? 皇帝觉得身上并没有穿上新衣,对这个问题骗子就是怎样解释的?

代词it可用作同位语从句的先行词。这个it常放在某些动词或短语动词后作宾语,同时兼作其后that同位语从句的先行词。

I owe it to you that I am still alive、幸亏您,我现在还活着。

有的语法学家把先行词it后的that从句瞧作就是动词或介词的真正宾语。一般认为,这种it后的that 从句应瞧作it的同位语,因为它相当于“主语+be+表语”结构。

You must see to it that the children don't catch cold、 (=You must see to it, and It is that the children don't catch cold、)您要当心,别让孩子们着凉了。

5、短语及固定句式后的同位语从句

I will come on condition that John is invited、如果约翰也被邀请的话,我就来。

简析:短语On condition, on supposition, on the ground(s), on the understanding, with the exception, in spite of the fact, on the assumption及句式There BE+no doubt(hope, chance, possibility,…)后的that从句为同位语从句。
