这句话是什么语法结构？ We ate great meals cooked by expert

非谓语动词追答cooked 是动词cook 的过去分词，作定语，修饰 meals追问哦 那究竟和哪个主语是被动关系 这个非谓语的主语是谁？追答如果你想用定语从句来改写这个句子，则是：
We ate great meals that were cooked by experts cooks.和meals是被动关系。大餐是被烹调的追问谢谢了追答非谓语动词的逻辑主语是great meals不客气，也谢谢你的采纳。

We ate great meals是常见的主谓宾结构，后面的非谓语动词（过去分词短语）cooked by ......是宾语meals的后置定语。

We ( 人称代词 ，主语） ate （ 谓语） great meals （ 宾语 ） cooked by experts 过去分词短语作定语） 这是一个简单句
要是定语从句 ， 句子就该变为
We ate great meals that were cooked by experts .
