message received 这种后置分词做定语的情况只能是message that is(was) received吧

message received 这种后置分词做定语的情况只能是message that is(was) received吧
这里的received是被动式的done是吧 不会有adj的情况吧.
有可能是message that has received这种情况么

messages received =messages that / which are / have been received.“已收信息”的意思.received是过去分词短语做后置短语,修饰messages,不能改为messages that have received,因为messages与received之间是被动...那怎么区分是are/have been呢有没可能是过去式的was呢 这种过去分词做后置定语就这2中可能是吧这种过去分词做后置定语,通常都是表示 have been,“已收信息”的意思
