回答1：

不可以。
prove是一个联系动词，它的过去式为proved，过去分词为proven，意思是“证明是”，后面可以接形容词或名词作表语，无被动语态。如：
We have been accused of exaggerating before, but unfortunately all our reports proved to be true.
In the past this process of transition has often proven difficult.
The experiment was to prove a source of inspiration for many years to come.
He proved to be a good father needs more things to do.

不是
这些要看你前面的语言结构

比如 He was proved to be 这就是被动了

比如 He proved to be a good father needs more things to do

这就不被动了

你的例句不成为被动语态
