I hope to be a physician praised.
I hope to be a doctor(who is)praised by people.
因为我这个人是要被别人称赞的
所以用被动.
您如果分不清被动,就不会理解
比如这个苹果被我吃掉了,
This apple is eaten by me.
还有一个地方,如果你没有学【定语从句】,你也不好理解.
I hope to be a doctor who is praised by people.
who is praised by other people就是【定语从句】,其中,who is可以省略,就变成:
I hope to be a doctor praised by other people.
