there was antoher sister who died

题目

there was antoher sister who died
there was another sister who died
为什么用who
there was another sister ,she is died

答案

there was another sister who died.对的,一个句子只能有一个谓语（即动词）；这里用who定语从句.
there was another sister ,she is died.不对的,was 和is 都是动词,一个句子不可以用2个动词.而且,she is died,这种说法也是错误的,死亡是不需要用被动形式的；形容一个人死了用dead,she is dead.
口语中有时也解释为某某人死定了.someone is dead.
