同位语从句和定语从句怎么区分

区别之分 :-同位语从句 = Noun Clause is in Apposition to a Noune.g. The report that she was killed is uncertain.that she was killed 是同位语从句,只能用 that这个关系代名称 Relative Pronoun。而不能用任何关系副词,如 : why, where, when, who... etc.定语从句 = Adjective Clausee.g. The report why the police wrote it is untrue.why the police wrote it是定语从句。关建是 : 必需采关系副词为主,有时也可用 that ,但其句法形式不能与上面同位语从句双同,如: The report that the police wrote it is untrue.否则就变成同位语从句子了。
