同位語從句與定語從句的區(qū)別是什么，二者有哪些不同，小編整理了相關信息，來看一下！

同位語從句與定于從句從形式上來看很相似，大多都是由that來引導，都跟在名詞或代詞后。但兩者在用法和功能上還是有很多區(qū)別的。

和先行詞的關系不同。對于同位語從句來說，同位語從句說明先行詞的具體內(nèi)容，二者是同位關系。而定語從句修飾限定先行詞，二者是修飾關系。

例如：The news that he told me is that Tom would go abroad next year.這個句子中第一個that引導的從句是定語從句，that在從句中作賓語。

The news that Tom would go abroad is told by him.而這個同位語從句中，that在句子中不作任何成分。

定語從句由關系代詞或是關系副詞引導，關系詞在從句中擔當相應的句子成分，可以做主語、賓語或表語等，但作賓語時常被省略。同位語從句主要有連詞that引導，在從句中不擔當成分。

還有，同位語從句與定語從句的引導詞也是不一樣的，what, how, if, whatever 等詞可以引導同位語從句，但不引導定語從句。同位語從句與先行詞可以用be動詞發(fā)展成為一個完整的句子，但是定語從句是不可以的。
