The Passive Voice
The passive voice is normally used when we are interested in the person or thing affected by the action rather than in the performer of the action. It is also used when the performer of the action is unknown. Passive sentences can only be formed from active ones containing an object. Consider these sentences:
Active:Sir Isaac Newton discovered the law of gravity.
Passive:The law of gravity was discovered by Sir Isaac Newton.
Form of Passive Sentences: (Passive) Subject + finite form of to be + Past Participle (Verb + -ed or 3rd column of irregular verbs) + (Agent = by-phrase)
When rewriting active sentences in passive voice, note the following:
- the object of the active sentence becomes the subject of the passive sentence - the finite form of the verb is changed (to be + past participle) - the subject of the active sentence becomes the agent of the passive sentence (or is dropped)
