同学你好~
这里passing都是修饰后面名词的定语，而不是宾语。
动词可以加ed或者ing变为形容词。

-ed形容词主要用来说明人的感受，含有“感到……”之意，
He was much amused by all this talk.  这一席话让他觉得十分好笑。

-ing形容词主要用来说明给人的感受，含有“令人……”之意，
He proved himself to be an amusing man.  他证明是一个有趣的人。

请再比较并体会以下句子：
He is frightened. 他很害怕。
He is frightening. 他很吓人。
He has a frightened look on his face. 他脸上带有惊恐的神情。
He has a frightening look on his face. 他脸上带有吓人的神情。
I read an interested expression on his face. 我看到他脸上露出一种感兴趣的表情。
I read an interesting expression on his face. 我看到他脸上露出一种有趣的表情。

祝同学学习进步~
