Active and Passive Voice
Voice The voice of a verb tells whether the subject of the sentence performs or receives the action. In English there are two voices, passive and active.
Active Voice In active voice, the subject performs the action expressed by the verb: The student wrote a song.
Passive Voice In passive voice, the subject receives the action expressed by the verb: A song was written by the student.
Forming Tenses of Passive Verbs
The passive voice always consists of two parts: a form of the verb "to be" + past participle:
Tense
Passive voice form
Present
it is cleaned
Past
it was cleaned
Future
it will be cleaned
Present perfect
it has been cleaned
Past perfect
it had been cleaned
Future perfect
it will have been cleaned
Uses of Passive Voice
Use the passive voice to:
Call attention to receiver of the action rather than the performer:
The professor was hit by three snowballs.
Point out the receiver of the action when performer is unknown or unimportant:A love letter was slipped under the door.
The signs will be posted.
Avoid calling attention to the performer of the action (known as the "institutional passive"):
The fines will be collected on Monday.
Active and Passive Voice in Writing
The choice between using the active or passive voice in writing is a matter of style, not correctness. However, most handbooks recommend using active voice, which they describe as more natural, direct, lively, and succinct. The passive voice is considered wordy and weak (except when used in cases above). Examine the following examples.
weak, passive: The skater was slammed into the wall by Maria.
strong, active:Maria slammed the skater into the wall.
weak, passive:
The book was enjoyed by me because the events of her childhood were described so well by the author.strong, active:
I enjoyed the book because the author described the events of her childhood so well.
