定语从句与同位语从句的区别方法及例题讲解

【定语从句与同位语从句的区别方法及例题讲解】1、句中含有that时 , 看that是否能省略 。定语从句中的that不仅起到连接词的作用 , 而且还充当句子的成分(主语、宾语等) , 往往可以省略 。例如:The apples that your mom bought yesterday were delicious.(其中 , that可以省略 。)
在同位语从句中 , that只起到连接词的作用 , 不充当句子成分 , 一般不能省略 。例如:It is a fact that he has done his best.
2、that与先行词的关系 。定语从句中 , that对先行词起到修饰、限定作用 。例如:This is the dog that I'm looking for.同位语从句中 , that对先行词起到解释、补充说明的作用 。例如:The news that he has died was true.
3、先行词不同 。定语从句中 , 先行词往往是具体的人或者事物 。例如:The pen that Tom takes is blue.同位语从句中 , 先行词往往是抽象性的名词 。例如:The news that Tiny will come is true.
4、引导词不同 。定语从句中 , 当指代人时 , 可以用who或者which来引导 , 而同位语从句不可以 。例如:The boy who is laughing is my brother.同位语从句中 , 引导词可以用how , what , whether , 而定语从句不能 。例如:I have no idea whether he'll come or not.
