请教left是什么成分

Her mother did of complications from the de-arming, and her brother died fighting in the revolution. I'm all she has left.

这个句子中all she has left中left该如何理解，到底left是all的定语，还是left是动词？重点是想弄了解错的那个为什么是错的，辛苦老师帮忙具体剖析一下，谢谢老师了！

 Left虽然有些词典标为形容词，但我觉得理解为过去分词最好, 由于通常都是做后置修饰的，

He's got plenty of money left...他还剩有大量的钱。

•They still have six games left to play.

left假如理解为完成体-ed:

 All she has left _ ，意思是她所抛弃的所有。

 Left假如理解为被动ed:

 All she has _ left, 意思是她所拥有些，被留下的，所有。

非常明显是第2个。
