1. He has broken the window.
2. The window has been broken by him.
3. The window is broken by him.
(Which one is the active voice sentence of #1?)
# 1 is in the active voice because it tells what he did.
#s 2 and 3 are in the passive voice because the subject (window) isn't taking any action.
In active voice the subject does something. The action goes Subect->
In passive voice the verb acts on the subject. The action goes Subject <-
