条件状语成分疑问

请问

A typical example is that once trapped by passing exams with only"correct answers"from textbooks,youngsters would gradually lose the motivation of truth-seeking. 

once引导的条件状从 为啥没有主语呢 是因为和表从主语一致,省略了么 如果是 那为啥谓语trapped没有被动啊

麻烦老师指点

once (they are) trapped by passing exams with only "correct answers" from textbooks, youngsters...

once引导的条件句省略了与主句相同的主语和动词be.
