The PASSIVE VOICE is often used in English – more often than it is used in other languages – as a way to avoid naming the subject, either because the subject is unknown or irrelevant, or else. However, there’s instances when a passive voice is used for other purposes – and the subject becomes an agent (the action is done by the agent).
Can you think why a speaker would use the passive voice+by+agent instead of the active voice+subject? Simple! Either the subject is unknown, or it is irrelevant.
Active: I keep the butter in the fridge.
Passive: The butter is kept in the fridge.
Active: They stole the painting.
Passive: The painting was stolen.
Active: They are repairing the road.
Passive: The road is being repaired.
Active: Shakespeare wrote Hamlet.
Passive: Hamlet was written by Shakespeare.
Passive: He was bitten by a dog.
