同位语从句与定语从句的区别

如题所述

定语从句和同位语从句的区别
第一:定语从句是一个形容词性的从句,如果把引导词前面的主句部分去掉则不能成立,如
I am a boy who is 12 years old ,如果把I am a boy 去掉,则这个句子who is years old就是一个不成立的句子
第二:而同位语从句是一个名词性的从句,如果把引导词及前面的中心词,和主句部分都拿掉的话,剩下的这个句子依然成立,如
The fact that the Sun is the center of the Solor System is questioned by some scientists.
把The fact that和is questioned by some scientists拿掉的话,the Sun is the center of the Solor System 依然成立,
以上两点就是定语从句和同位语从句的最大区别。

同位语从句是名词性从句(主语从句、表语从句、宾语从句、同位语从句)中的主要从句之一,从句作同位语表示与之同位的名词(短语)的实际内容,它的作用相当于名词,对前面的名词(短语)加以补充说明或进一步解释。定语从句(Attributive Clauses)通常皆放在它所修饰的名、代词之后,这种名、代词就叫做先行词。定语从句中的引导词要充当句子成分。而同位语从句就不需要,而且常常是一些抽象的名词如news(消息)fact,qustion等我给你分析一下句子吧
The news that he has just died is true 同位语从句
这句话中that后面的成分都不缺,即he has just died 是完整的所以不是定于从句,that he has just died 是补充说明是一个说明样的消息,句子的主干是The news is true.
This is the book (that)i like.定语从句
This is the book是主句,后面的就是限定了,即定于从句。book是先行词,that是引导词 在从句中做宾语(作宾语是可以省掉)什么样的书呢,就是我喜欢的书。like 是及物动词后面要宾语成分不完整要加宾语that,that指代book 要记住定语从句中都是缺什么补什么,当是宾语的时候可以省。
1 The fact that he has already died is quite clear同位语从句
2 The idea that he we could ask the teacher for advice is wonderful同位语从句)
3 Water. which is a clear liquid. has many uses(定语从句,从句中缺少主语,which补上了)
4 I have a sister who works in a bank.定语从句

He told us the news that /which /he learned from our teacher
He told us the news that he had got No 1 in the exam.
第一句是定语从句,先行词news 在从句中充当learned 的宾语。可以用which 代替。也可以省略。第二句是同位语,news 在从句中不充当任何成分,但是不可以省略。
