What are the rules for active and passive voices?

Answer 1

You cannot be anyone else be yourself sing like you want we won't stop you

1. Passive voice should be used sparingly.
2. If the Doer of the action is mentioned, don't use passive voice.
3. Only transitive verbs have passive voice.
4. The subject of a passive sentence is not the Doer of the action. It is the receiver of the action. If the doer is to be mentioned in the passive voice, it is preceded by 'by and followed by objective case of pronoun.
Examples;
He likes apples. (Active).
Apples are liked (by him). Passive
I shall help him. (Active)
He will be helped (by me). Passive

Answer 2

In active voice, the subject performs the action of the verb, while in passive voice, the subject receives the action of the verb. Active voice is generally more direct and clear, while passive voice is often used when the focus is on the recipient of the action or when the doer is unknown or less important. To change a sentence from active to passive voice, the object of the active sentence becomes the subject of the passive sentence, and the verb is changed to a form of "to be" plus the past participle.
