定语从句与同位语从句的区别方法及例题讲解

更新时间:2021-02-20 20:13:06

  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.
