同位语从句及引导词 篇2

[同位语及充当同位语的形式]

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。单词、短语、直接引语以及从句都可以充当同位语。

1. 单词作同位语。

①This is my friend Harry.

②We both come from Hunan.

③We Chinese are brave and hardworking.

④You three take these seats.

这几个句子中Harry，both，Chinese和three都是同位语。

2. 短语作同位语。

①He says that Computertown UK was formed for just the opposite reason， to bring computers to people and make them “people-literate”.

②Wang Li， just back from the training class， was made director of the Maternity Home.

③People， old and young， took to the streets to watch the parade.

这几个句子分别采用了不定式、介词短语和形容词作同位语。

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？”

这个句子里则采用了直接引语来充当同位语。

[同位语从句及其位置]

按照同位语的概念，同位语从句就是在复合句中充当同位语的名词性从句，用来表示与之同位的名词或名词短语的实际内容，或对前面的名词或名词短语加以补充说明。一般情况下同位语从句跟在某些名词如news，idea，fact，promise，question，doubt，thought，hope，message，suggestion，words（消息），possibility等（一般的“抽象”名词都可以）的后面，用以说明该名词所表达的具体内容。比如在I’ve come from Mr Wang with a message that he won’t be able to see you this afternoon.这句中，that从句表示的就是message的内容。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，这在语法上叫做分隔式同位语从句，如The thought came to her that maybe she had left the door open when she left home.就是个很典型的例子。还有一些短语及固定句式后的同位语从句，如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从句都为同位语从句，如I will come on condition that John is invited.

[同位语从句的引导词]

同位语从句最常见的引导词是that和whether。这里值得提到注意的有两点：一是同位语从句中的that不能省略，二是虽然if和whether都有“是否”的意思，但是if不能引导同位语从句。

以下两个句子分别含有that和whether引导的同位语从句：

①The idea that you can do this work well without thinking is quite wrong.

②The question whether we should call in a specialist was answered by the family doctor.

除了这两个引导词，连接代词what，who，whom，whose和连接副词when，where，how，why也可以引导同位语从句。

①I have no idea what size shoes she wears.

②The question who will take his place is still not clear.

③We haven’t yet settled the question where we are going to spend our summer vacation.

这三个句子分别含有以what，who和where引导的同位语从句。

[同位语从句和定语从句的区别]

同位语从句和定语从句很容易被混淆，因为它们在句子形式上相近。它们的差别在于：

1. 先行词的区别。

定语从句的先行词是名词或代词，而同位语从句的先行词只能是名词，而且仅限于idea，plan，fact，theory，promise，hope，news，doubt，truth，information，suggestion，question，thought，belief，conclusion等少数名词。

nlc202309042301

2. 引导词的区别。

首先，that既可引导同位语从句又可引导定语从句，其区别在于：同位语从句由连接词that引导，连接词that本身无意义，在同位语从句中不充当任何成分，不可省略，不可以用其他词替代；而定语从句由关系代词that引导，关系代词that在从句中充当一定的成分，作宾语时可省略。

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，划线部分是同位语从句，that没有任何意义，只起连接作用。

其次，由when，where，why引导的同位语从句和定语从句的区别在于：同位语从句由连接副词引导，只起连接作用，没有指代作用；定语从句由关系副词引导，关系副词具有指代先行词的作用，常用一个介词加关系代词替换。

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。

3. 意义的差别。

同位语从句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；而定语从句是限制所修饰名词的，它的作用是将所修饰的名词与其他类似的东西区别开来。

①We are glad at the news that he will come.

②We are glad at the news that he told us.

在①句中，news的内容就是he will come，故that引导的是同位语从句，而②句中，that从句是限制the news的内容的，即我们高兴只是因为他告诉的这个news而不是其他的news，故that从句为定语从句。

[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。

①Our teacher gave us some advice how we（should） use the computer.

②She made a request that the doctor （should） be sent for at once.

如果在高考英语试题中，同位语从句出现在语法填空的题型中，特别提示同学们一定要按照三个步骤来完成：第一步确定引导词，第二步注意从句中的语序要用陈述句的句式，最后则要关注从句中的谓语部分的时态语态或者虚拟语气的用法。

表语从句和同位语从句的区别 篇3

引导表语从句的词有连词that, whether，连接代词和连接副词，关系代词型what，以及as if, as though, because等连词。

1、 由that引导

The question is whether the film is worth seeing. 问题是这部电影是否值得看。

注意：whether 可引导表语从句，但与之同义的if却通常不用于引导表语从句。

2、由连接代词引导

You are not who I thought you were. 你已不是我过去所想像的.人。

3、由连接副词引导

The problem is how we can find him. 问题是我们如何找到他。

4、由关系代词型what引导

He is no longer what he was. 他已经不是以前的他了。

5、由as if / as though引导

同位语从句例句 篇4

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忙他的学习?(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。如:

The news that our team has won the game was true。 我们队赢了那场比赛的消息是真的?(同位语从句，补充说明news到底是一个什么消息?)

The news that he told me yesterday was true。 昨日他告诉我的那个消息是真的?(定语从句，news在从句中作told的宾语?)

I made a promise that if anyone set me free I would make him very rich。 我许诺如果谁让我自由，我就让他十分富有?(同位语从句，补充说明promise到底是一个什么诺言?)

The mother made a promise that pleased all her children。 妈妈做出了一个令她的孩子们高兴的许诺?(定语从句，promise在从句中作pleased的主语?)

3。 从引导词及其在句子中的成分上区别

有些引导词如how， whether， what能够引导同位语从句，但不能引导定语从句?如:

That question whether we need it has not been considered。 我们是否需要它这个问题还没有研究?(同位语从句)

I have no idea what has happened to him。 我不明白他发生了什么事?(同位语从句)

引导词that引导定语从句时，在从句中一般作主语或宾语(指物时还能够用which代替)，并且作宾语时常常省略?that在同位语从句中仅起连接作用，不充当任何成分，并且不能省略，也不能用which来代替?如:

The order that we should send a few people to help the other groups was received yesterday。 我们应派几个人去帮别的几个小组的命令昨日收到了?(同位语从句，是对order的具体解释，that虽不作成分，但不能省略?)

语法讲座之同位语从句 篇5

1. 定义：用作同位语的从句叫做同位语从句。

2. 用法：同位语从句的先行词多为fact, news, idea, thought, question, reply, report, remark等，关联词多用从属连词that。如：

They were all very much worried over the fact that you were sick.

对你生病这件事，他们都很焦虑。

Where did you get the idea that I could not come?

你在哪儿听说我不能来?

Early in the day came the news that Germany had declared war on Russia.

德国已对俄国宣战的消息一大早就传来了。

注：同位语从句偶尔由从属连词whether引导。如：

I have no idea whether hell come or not. 我不知道他是否来。

连接代词who, which, what和连接副词where, when, why, how亦可引导同位语从句。

The question who should do the work requires consideration.

谁该干这项工作，这个问题需要考虑。

We havent 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。

It is a question how he did it.

那是一个他如何做了此事的问题。

重点疑难

1.that引导的同位语从句与定语从句之区别

that引导的同位语从句 that引导的定语从句

句法功能上 that只起连接从句的作用，无意义。在从句中不充当句子成分。不可省。 that替代先行词在从句中不仅起连接作用，还充当一个句子成分。如在从句中作动词的宾语时可省略。

意义上 从句是被修饰名词的内容。 从句起限定作用，是定语

如：The news that Mr. Li will be our new English teacher is true. (同位语从句，that不可省。)

李先生将是我们的新英语老师这个消息是真的。

The news (that) he told me yesterday is true. (定语从句，that在从句中作told的宾语，可省。)

他昨天告诉我的消息是真的。

2.一些表示“建议、命令、要求”的名词后所跟的同位语从句中，谓语动词用虚拟语气should+动词原形表示。should可省。如：

This is our only request that this (should) be settled as soon as possible.

这就是我们唯一的请求：尽快解决这个问题。

在复合句中作表语的从句称作表语从句，位于连系动词（be，seem，remain等）之后。1.that 引导的表语从句

连接词that 仅起连接作用，无意义，在句中不作任何成分，通常不可省略。这种从句往往是对主句主语的内容起进一步解释的作用。

连接词whether起连接作用，意为“是否、究竟、到底”，（注意：if不能引导表语从句)在句中也不作任何成分。

The question is whether what man will turn up in time.3.what, which, who, whom, whose引导的表语从句

连接副词where, when, why, how除在句中起连接作用外，在从句中还充当时间、地点、方式、原因状语，本身具有词义。

2013年高考英语试题定语从句部分训练题（1）答案解析

1.【解析】题干的意思是：“生态系统是由一个区域里相互作用的生物和非生物构成的”。分析句子结构，interact with one another是定语从句，先行词是the living and nonliving things，通过还原法可知，先行词在从句中作主语，不是人，所以用that。务必记住：what不可引导定语从句。故选择A.2.【解析】考查定语从句。where引导的定语从句修饰platform，where再从句中充当地点状语。先行词从句主干是否完整，确定关系代词或关系副词在从句中充当什么成分。故选择B。

3.【解析】本题考查定语从句。as在此句中引导非限定性定语从句，放在句首，同时在从句中作主语，为正确答案；如果用it或者that，那么整个句子中缺少一个连词，排除选项A和B； 如果用what，逗号前面应该是一个主语从句，主语从句之后应该是谓语动词，而不是逗号之后再来一个句子，排除。句意：等医生到的时候，Amy好多了，孩子都这样。故选择B。

4.【解析】本题考查定语从句。the environment是先行词，在定语从句中做地点状语，“他们生活在这个环境中”，故用关系代词where。句意：现在人们更加关心他们所生活的环境。（拓展：关系词的选择，最关键的就是看先行词在定语从句中作什么成分，而不是看先行词是表示什么的单词，如表示地点的先行词之后未必用where，同样表示时间的先行词之后未必用when。）故选择D。

5.【解析】本题考查定语从句。定语从句的先行词为island，而先行词在从句中所做的成分是主语，所以用关系代词that或which；when和where引导定语从句时用做状语；而whom引导定语从句时做宾语。句意：最终他们到达了一个完全与外界隔绝的荒岛上。故选择C。

6.【解析】本题考查as引导的非限制性定语从句。That是不可以引导非限制性定语从的；而when和where引导定语从句时不做主语。句意:没有简单的答案，正如科学界的许多情况一样。故选择A。

7.【解析】本题考查非限制性定语从句。分析句子结构，He may win the competition为主句，剩下的只可以为从句，故先排除B。本题中，in which case引导非限制性定语从句，相当于and in that case。（注：what不可引导定语从句。）故选择A。

8.【解析】考查定语从句。解题关键是判断定语从句关联词的选择方法，即：根据先行词在定语从句中做的成分来判断。本题中先行词letter在从句中做地点状语，因此，正确答案为C。句意：他写了一封信，在信中他解释了事故中发生的一切。（注：what与how都不可以引导定语从句。）故选择C。

9.【 解析】本题考查固定短语在语境中的使用。A.take a share分担……，为……出力 B.take a chance冒险 C.take a turn转弯，转；（情况、形势等）转变 D.take a lead领先，带头。根据本句，for the better的提示，可见是讲转变，变得更好，句意：有了源于其他食品文化的灵感，美国饮食文化可以变得更好。故选择C。

10.【解析】考查定语从句。who指代先行词those（那些人），在从句中做主语，whom不能做主语，which指物，what不能引导定语从句，故选择B。句意：幸福和成功总青睐能善于意识到自己长处的人们。（解题技巧：找主干，析从句。1.找主干：因为主句完整，Happiness and success often come to those.不难看出本题考查定语从句，排除what。

2.析从句:____are good at recognizing their own strengths,缺主语，先排除whom，先行词those（那些人），排除which，故选择who。）故选择B。

11.【 解析】本题考查定语从句。____ lives were affected.是定语从句，修饰those，从句的主语是____ lives，缺修饰语，所以选whose。句意：这本书从经历过地震的人的角度来

讲述地震的故事。故选择A。

12.【解析】本题考查定语从句的连词。空处之后是一个定语从句，先行词是park，在定语从句中作地点状语，“in the park”，故应该选用关系副词where。句意：许多国家都在建立国家公园，可以保护很多动植物。（方法技巧：定语从句中关系词的选择取决于在定语从句中的句法作用，要看它做什么成分，而不是表示什么，如表示时间，地点等的先行词，在定语从句中未必就是做时间或者地点状语，如果是做主语，宾语，表语，那就不能用关系副词when，where，而应该根据具体情况，选用关系代词。）故选择D。
