ACTIVE AND PASSIVE VOICE

Active Voice :

When using the active voice, the subjects are the ones performing the action.

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 avoice.
Passive Voice :

In the passive voice, the verb takes an object.

All men are loved by God.
Nests are built by birds.
Bones are eaten by dog.

These sentences are in passive voice. 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.

How to convert active voice sentences into passive voice :

First move the object in the active voice to the subject position. Use the appropriate ‘be’ verb such as (is/am/are/was/were/has been/have been/shall be/will be). For example :

Active Voice Passive Voice
Columbus discovered America. America was discovered by Columbus
Who did this work? By whom was this work done?
Open the window Let the window be opened
He is writing a letter A letter is being written by him
The work will be finished by me I will finish the work
Somebody cleaned the room yesterday The room was cleaned yesterday
