2. 1. Purposes of Passive Voice
1. When the doer of an action is not know
2. When the object of an action is the emphasis

3. 1.1 When the doer is not known
Example:
The window has been broken. Who has broken it?
In this case, we do not know who broke the window. Instead of starting the sentence with ‘Somebody has broken the window.’, we can also start the sentence with the window.

4. 1.2 When the object of the action is the emphasis
Example:
This murderous killer was sentenced a life’s imprisonment.
In this case, we do not care about who made the judgement. Instead, our emphasis is put on the murderous killer. So, we start the sentence with ‘the killer’.
