There's none left 什么都没剩下?

There's none left 什么都没剩下? there's none left的意思 there's none left.请问这里的left是什么意思呢? 新概念第一册there's none left中的left there was none left 翻译 there is none left there is none left为什么left在none后面? there's none left.中left是leave的过去分词,那这一句是现在完成时吗?为什么不用加have/ha there is none left中left为什么用过去分词? 是There was none left.还是There were none left. 谓语动词用单数还是复数? there is none there are none都对吗? left.there is none left.I'm one of the few people left.
