In the active voice, the subject of the sentence performs the action: I aced the exam. Subject/actor verb object/thing acted on
In the passive voice, the object of the action becomes the subject of the sentence, and the actor appears in a prepositional phrase, or is absent from the sentence: The exam was aced (by me). Subject verb actor/object of prepositional phrase ► Use the active voice when the actor’s identity is important. Active: The butler did it. Passive: It was done by the butler.
The first sentence is stronger; it sounds like an accusation. The second sentence is weaker; it sounds like the butler did nothing more sinister than a load of laundry. ► Use the active voice when you want to be direct and emphatic. Active: Management expects the staff to follow the rules. Passive: It is expected by Management that the rules will be followed by the staff.
In this instance, the active voice delivers the message more effectively. ► Use the passive voice when you do not need to tell the reader who is acting. Active: Ned will prosecute trespassers. Passive: Trespassers will be prosecuted.
In this case, it is not necessary to say who will be doing the prosecuting. Fear of being prosecuted, not fear of being prosecuted by Ned, will prevent most people from trespassing. ► Use the ‘objective’ passive for writing in disciplines such as the sciences. Active: Dr. Cranium considered the drug to be a medical breakthrough, but after he tested the drug further, he found that it had serious side effects. Passive: The drug was considered to be a medical breakthrough, but after further testing, it was found to have serious side effects.
Writers in the sciences often use the passive voice when they want to sound objective. In the first sentence, the active voice suggests that Dr. Cranium made an error in judgement. In the second sentence, the passive voice delivers important information about the drug without implying anything (either positive or negative) about Dr. Cranium.
