Voice is a grammatical category that applies to the verb in a sentence. It shows the relationship between the doer of an action (subject) and the receiver of that action (object).
There are two types of voice:
1. Active voice
2. Passive voice
The active voice, at its most fundamental level, highlights the person or agency who performs an action, or the "actor." The passive voice highlights the action's recipient or, in rare occasions, the action itself.
• The cat caught the mouse.
• The mouse was caught by the cat.
Basic rules to change active voice into passive voice:
• Change the places of subject and object.
• Use the helping verb according to the tense.
• Use third form of the verb.
• Add ‘by’ if necessary.
• If the subject is a pronoun change it into the objective case.
• ‘Being’ is used in continuous tense.
• ‘Been’ is used in perfect tense.
• Future continuous and modal continuous tenses cannot be changed into passive voice.
• If ‘be or its forms’ is used as a main verb in a sentence, the sentence cannot be changed into passive voice.
Imperative sentences: Imperative sentences are used to convey an order, request, advice, suggestion, etc.
While converting these sentences into passive voice, we use ‘you are ordered/ requested/ advised, etc.’
• Shut the door. (Active voice)
• You are ordered to shut the door. (Passive voice)
We can also change the voice of an imperative sentence (with an object) in the following manner.
• Shut the door. (Active voice)
In the above given sentence we have an object i.e. door.
• Let the door be shut. (Passive voice)
