Voice change – Active voice to passive voice

Voice change rules

 

Voice is the form of the verb which indicates whether the subject does the work or something has been done to it.
There are two types of voice:
Active voice.
Passive voice.
Active voice: When using the active voice, the subjects are the ones performing the action.
Structure:
Subject + verb + object.
Examples:
I do the work.
God loves all men.
Birds build nests.
Dog eats bones.
In these three sentences the subject does the action. Hence they are in the active voice.

Passive voice: In the passive voice, the verb takes an object.

Structure:

Object + be verb + Past participle of verb + by+ subject.

Examples:
The work is done by me.
All men are loved by God.
Nests are built by birds.
Bones are eaten by dog.
These sentences are in passive voice.
Why the Passive voice is used in English ?
(a) To stress the action done rather than the doer of the action
(b) If the doer is unknown
(c) When it is more convenient.
