同位语从句与非限制性定语从句的区别

同位语从句与非限制性定语从句的区别
例如：
(07崇文一模）-what would you do?
-I'd get a job doing something exciting,WHERe I could meet interesting people and travel a lot
它是非限制性定语从句还是同位语从句?
如何把非限制性定语从句改写成同位语从句,反之又如何?

概念
【1】非限定性定语从句的作用是对所修饰的成分作进一步说明,通常和主句间用逗号隔开,将从句拿掉后其他部分仍可成立.
【2】在复合句中用作同位语的从句叫同位语从句.
区别
【1】从意义上看,同位语从句是名词性从句,是对一个名词加以补充说明,定语从句是形容词性的,对一个名词加以修饰限定.
【2】从结构上看,同位语从句的连接词不充当句子成分,但不可省略；定语从句的关系代词代替先行词在句中充当成分,充当宾语时可省略.
综上所述,上面的句子是非限制性定语从句.二者互相转换,会使句子显得蹩脚.因为可跟同位语从句的通常是一些具有一定内容含义的名词.常见的有：conclusion evidence fact hope idea news opinion problem promise reason
truth.
I'd get a job doing something exciting,WHERe I could meet interesting people and travel a lot .主句I'd get a job doing something exciting中
doing something exciting是分词短语,不是从句.回答者：lrqshuai答案错了.
