judging from为何意,怎么样用?

judging from/by 由.判断,judging from 用作独立结构,即不用考虑从句和主句逻辑关系的一致性,用法相当与：generally speaking,considering (考虑到）e.g.:judging from the truth,he is honest enough.
e.g.judging from the view,the earth is round.
从这两个例句中我们可以看出,不管主句主语为人、物、judging from 都不变,不会写成judged from
非独立结构则要考虑主从句的逻辑关系,
如：having finished the work,i went out
此处havcing done为主动 ,若主语变了,主动被动就会变,
e.g.:hit by the man,the little boy became angry.
