如果你需要既含有定语从句又含有同位语从句的句子,那说明你英语语法应该很好才对.那么讲解他们的区别就显得没必要了吧?
eg. I don't know the man who told me the news that my car had been stolen.
句子中 who told me the news that my car had been stolen 是定语从句,修饰the man
that my car had been stolen是同位语从句,说明the news 的内容.
区别： 定语从句用来修饰前面名词,翻译成...的... 关系代词在定语从句中作主语,宾语或表语
同位语从句用来详细说明前面名词的内容,引导词that在从句中并不充当成分.
希望能帮到你.
