同位语从句和定语从句的区别是什么 如何区分
同位语从句和定语从句的区别是什么如何区分定语从句对先行词起修饰限定作用,有主次关系,先行词可为任何名词.同位语从句和前面的名词是并列关系,前面的名词一般包含着内容,如NEWS.定语从句引导词在从句中充当某种句子成分,同位语从句引导词在从句中不担当任何成分.同位语从句和定语从句的区别1同位语从句和定语从句的区别一，作用不同：同位语从句是解释说明名词的具体内容。
定语从句没有说明名词的具体内容，而是修饰某个名词或者代词。
二，可用同位语从句说明的名词大多数是抽象名词，主要有news , idea, fact, belief, question, truth, word(消息), doubt, evidence，order(命令）。
而定语从句所修饰的词既可以是抽象名词，也可以是具体的名词。
既可以是名词，也可以是those，anything，anybody，all这样的代词。
三，从句引导词不同：一般情况下，引导同位语从句的词主要是that。
当名词是question或者problem的特殊情况下，用于提问的疑问词一般都可以用在同位语从句中。
这包括：which, who, where, when, what , why等疑问词。
而定语从句中，一般情况下，that，which ，who，where ，where，why ，how等都可以引导定语从句。
2如何区分同位语从句和定语从句如果名词后的that从句是完整的，就是同位语从句；如果从句缺少主语或宾语，就是定语从句。
That从句在所有名词性从句中，都只是连接主从句的连词，没有任何意义，不在从句中充当句子成分；That从句在定语从句中是关系代词，不但连接主从句，还要指代被修饰的名词和代词（即先行词）在从句中做主语或宾语，也就是说定语从句中必定少个主语或宾语！。
高三语法复习 同位语从句及其与定语从句的区别(习题带答案)
同位语从句同位语,就是用来补充说明名词的成分。
当我们用一个完整的句子来补充说明名词时，即构成同位语从句。
所以同位语从句都是位于一个名词后面，用来进一步说明前面的名词的内容，这个名词就是同位语从句的先行词。
名词性从句分别是由陈述句，一般疑问句和特殊疑问句变化而来。
一、陈述句作同位语The fact that he succeeded in the experiment pleased everybody.同位语从句可能与其修饰的名词被其他成分隔开。
A saying goes that practice makes perfect.一、一般疑问句作同位语They are faced with the problem whether they should continue to work.二、特殊疑问句作同位语I have no idea when he will return同位语从句主要是由that引导，而很少用whether以及连接代词或连接副词引导，这是因为我们多是用陈述句来补充说明名词的内容，而很少用一般疑问句或特殊疑问句来补充说明名词的内容。

同位语从句与定语从句的的语法区
同位语从句与定语从句的的语法区同位语从句与定语从句的的语法区导语：以下是店铺搜集并整理的“同位语从句与定语从句的的语法区”有关内容，希望在阅读之余对大家能有所帮助!1.意义的不同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：We are glad at the news that he will come. 听到他要来这个消息我们很高兴。
(news的内容就是that he will come，故that引导的是同位语从句)We are glad at the news that he told us. 听到他告诉我们的这个消息我们很高兴。
(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)2.引导词的不同what, how, if, whatever 等可引导名词性从句，但不引导定语从句。
3.引导词的功能上的不同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。
4.被修饰词语的区别同位语从句所修饰的名词比较有限，通常有hope, wish, idea, news, fact, promise, opinion, suggestion, truth等，而定语从句所修饰的名词则非常广泛。
另外，when和where 引导定语从句时，通常只修饰表示时间和地点的名词，而它们引导同位语从句时却不一定;又如why引导定语从句，它通常只修饰名词the reason，而它引导同位语从句时则不一定：I have no idea when they will come . 我不知道他们什么时候来。
同位语从句与定语从句
同位语从句与定语从句同位语从句和定语从句一样通常都放在由名词充当的先行词后面, 且其先行词和关联词特点与定语从句先行词及关联词特点十分相似,极易混淆,不过两者的区别还是十分明显的。
1. 从句性质不同同位语从句属于名词性从句,是用来进一步解释或补充说明前面的名词;而定语从句是用来说明先行词的性质或特征,起修饰或限制的作用,与先行词的关系是修饰与被修饰的关系,从句相当于形容词。
例1:The plan that you will go there next week has to be changed.你准备下周去那里的计划得改变.析:认真分析语境含义及句子结构可知,从句为The plan的具体内容,因此该句为同位语从句。
例2:The news that he told me was false.他告诉我的消息是假的。
析:认真分析语境含义和句子结构可知,从句是用来修饰The news的, 因此该句为定语从句。
2.关联词作用不同定语从句的关联词在从句中作主语、宾语、时间状语、地点状语和原因状语等,而同位语从句的关联词在从句中不担任成分。
例1:The plan t hat I”ll stay there for a week can”t come true.我要在那儿呆一周的计划不能实现。
析:分析句子成分可知,that在从句中不作任何成分,因此该句为同位语从句。
例2:The plan that he raised was reasonable.他提出的计划合理。
析:that在从句中作宾语,因此该句为定语从句。
3．同位语从句先行词不同同位语从句的先行词就是被同位语从句解释说明的名词,因为它和同位语从句在内容上相同,因此常为一些体现一定内容的名词,如:hope, plan, fact, news, problem, truth, idea, information等,此时同位语从句具体介绍这些名词的内容。
同位语从句的先行词虽然体现同位语从句的内容,但在同位语从句中并不充当成分。
(完整版)同位语从句和定语从句练习
同位语从句讲解与练习1定义：用作同位语的从句叫做同位语从句，用以解释说明某一名词内容和实质的从句。
2.连接词：that, whether, why, who, where, how, when等。
引导同位语从句时一般都不省略。
if一般不引导同位语从句that, whether不作成分，whether表示“是否”E.g. They were all very much worried over the fact that you were sick.对你生病这件事，他们很焦虑。
Where did you get the idea that I could not come?你在哪儿听说我不能来？I have no idea whether he’ll 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，在句中作成分。
E.g. 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 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。
It is a question how he did it.那是一个他如何做了此事的问题。
3.可跟同位语从句的名词或短语不是所有的名词都可以跟同位语从句，常可以被同位语从句修饰的名词有：belief doubt explanation hopeidea news opinion possibilitystatement thought wish truthfact question promise problemreply report suggestion advicefear warning understanding feelingrumor certainty probability on conditionon the understanding with the exception in spite of the factE.g. Daniel will be allowed to make a trip to China on condition that he gets an A in all his school subjects.4同位语从句与定语从句的区别1）that引导的同位语从句与定语从句之区别句法功能上that引导的同位语从句that只起连接从句的作用，无意义。
同位语从句和定语从句的区别
同位语从句和定语从句的区别同位语从句和定语从句的区别同位语从句与定语从句从形式上来看十分相似，大多都由that来引导，都跟在名词或代词之后，这也很容易导致同学们在理解或做题时出现错误，而这两者在实质上是截然不同的，句法功能都有所不同，具体有哪些不同呢？以下是店铺精心为大家整理的有关同位语从句和定语从句的区别，希望对大家有所帮助，欢迎阅读。
同位语从句和定语从句的区别1同位语从句只能用that做连接词，且that在从句中不做成分，一般修饰idea，plan，assumption，suggestion等。
定语从句的连接词that只是众多连接词中的一个，that要做从句中的主语或宾语，先行词既可以是人，也可以是物。
1）Kelly thought of an idea. North Korean can kidnap an American in case tension with the U S. continue to escalate.这是两个独立的简单句，但都是完整的。
所以用句号。
把这俩合成一个句子就是，把句号去掉，第二个句子前加that。
先行词是idea。
kelly thought of an idea that North Korean can kidnap in case tension with the U.S. continue to escalate.Kelly相出了一个主意，在北韩与美国紧张持续升级的情况下，北韩可以绑架美国人。
在从句的谓语动词can kidnap前有它自己的主语north Korean。
that只起连接作用。
同位语从句的从句不缺主语和宾语2）Kelly thought of an idea. The idea made America administration very tense and strained.这也是两个简单句。
句子中间用句号。
但第二句的主语idea和第一句的idea是一个词。

如何区别定语从句与同位语从句
如何区别定语从句与同位语从句
定语从句和同位语从句有一些区别，可以从以下几个方面进行区分：
1.位置：定语从句通常紧跟在被修饰的名词之后，而同位语从句通常
紧跟在所解释的名词或名词性短语之后。
例句：
- 同位语从句：Her hope, that she would pass the exam, motivated her to study hard.（她希望通过考试，这激励她努力学习。
）
2.释义关系：定语从句是为了对被修饰名词进行限定、修饰或描述，
起到修饰定语的作用；同位语从句是对所解释名词的解释、说明或进一步
阐述。
例句：
- 定语从句：The movie that I watched last night was very exciting.（昨天晚上我看的电影非常刺激。
）
- 同位语从句：The fact that he passed the exam surprised everyone.（他通过考试的事实让每个人都感到惊讶。
）
3.引导词：定语从句一般由关系代词或关系副词引导，而同位语从句
一般由“that” 引导。
例句：
- 定语从句：The girl who is standing over there is my sister.（正在那边站着的女孩是我妹妹。
）
- 同位语从句：The news that he won first prize made me happy.（他获得一等奖的消息让我很开心。
）
综上所述，通过定语从句和同位语从句的位置、释义关系和引导词等方面的区分，可以准确判断两者之间的区别。
