同位语从句、定语从句区别
  that 既可引导同位语从句又可引导定语从句,其区别在于:1.同位语从句由连接词that引导,连接词that本身无意义,在同位语从句中不充当任何成分,不可省略,不可以用其他词替代;2.定语从句由关系代词that引导,关系代词that在从句中充当一定的成分,作宾语时可省略.
由when,where,why引导的 同位语从句和定语从句的区别在于:同位语从句由连接副词只起连接作用,没有指代作用; 定语从句由关系副词引导,关系副词具有指代先行词的作用,常用一个介词加关系代词替换.例如:I will never forget the day when we first met.(定语从句,when为关系副词) That is the special day (which/that) I will never forget.(定语从句,which/that为关系代词,作forget的宾语) This is the house where we lived fifteen years ago.(定语从句,where为关系副词) This is the house which we sold fifteen years ago.(定语从句,which为关系代词,作sold的宾语).
