For example: She is reading a book.
Passive voice: In the Passive Voice, the Verb is related to the receiver of the action, and the focus is on the action. We have seen in the examples given earlier, 'Short Passives' where the performer of action (agent) is not identified.
For example: The plants are watered by her everyday.
Uses of passive voice:
1. We use passive voice when the subject is not that important that is, when 'what happened' is more important.
For example: I made a mistake. - a mistake was made by me.
(Here making a mistake is more important than who did it)
2. We also use passive voice when the subject is unknown.
For example: someone left a phone in the hall. - a phone was left by someone in the hall.
Rules for changing voice:-
(i) Verb should be in transitive form.
(ii) Subject and object are replaced with each other.
(iii) Verb of the sentence undergoes a change
That is verb is changed into 3rd form
Example: play - played, enjoy - enjoyed, walk - walked, talk - talked.
(iv) We add helping verb according to the tense of the sentence.
(v) Nouns change according to the need. They turn into passive form
Example: he - him, she - her, I - my, we - us.
(vi)'By' is added with the subjects in some cases.
