is there anything left to eat 为什么用left
is there anything left to eat
为什么用left

is there anything left to eat 为什么用left
left是anything的定语,left的逻辑主语是anything,left与anything之间是动宾关系,所以用表示被动的过去分词left.如果是主谓关系,则用表示主动的现在分词,如Is there anybody leaving for Beijing?
还可以通过下列变式来理解
Is there anyting left to eat?=Is there anything that is left to eat?
Is there anbody leaving for Beijing?=Is there anybody who is leaving for shanghai?

过去分词做anything的后置定语

leave的过去式,表示剩下的意思,同时是被动句,所以要用过去式

这是一种习惯用语

left是指剩下的意思,就是说还剩下什么东西可以吃。

动词被动形式做后置定语

leave的过去分词
修饰anything

left 这里 是leave 的过去分词,做“剩下, 留下”讲。作后置定语修饰 anything。
这句的意思是:还有甚么剩下可吃的食物吗?

“还有吃的东西吗?”
修饰sth,anything,everying等不定代词的动词要后置
此处过去分词left做anything的后置定语,另外anything有得到对方肯定回答的意思

过去分词作定语修饰anything
