there is none left为什么left在none后面?

there is none left为什么left在none后面? 翻译 there is none left there is none left中left为什么用过去分词? there was none left left.there is none left.I'm one of the few people left. there's none left的意思 there was none left.如果不是was,而是is,left要改成leave. 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 是There was none left.还是There were none left. 谓语动词用单数还是复数? 英语翻译I'd like some more bananas.I'm sorry,there is none left. 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
