Passive Voice


The passive voiceis a structure that allows you to make a statement
without knowing who performed the action of the sentence: The
house was destroyed.Or the person who performed the action is
placed in a passive positionin the sentence: The house was destroyed by
soldiers.
An activesentence is commonly structured subjectverbdirect
object. A passivesentence changes that structure to direct objectused
as the subjectto bepast participlebysubjectused as the object
of the preposition. Let’s compare the two structures:
Active Sentences Passive Sentences

Kim finds the dog. The dog is found by Kim.
We buy his car. His car is bought by us.
The girls stole the purse. The purse was stolen by the girls.
They solved the problem. The problem was solved by them.

The verb to bein the passive sentences is conjugated in the same
tense as the verb in the active sentences. Look how the various
tenses appear in the passive:
Tense Passive Sentences

Present The house is destroyed by the soldiers.
Past The house was destroyed by the soldiers.
Present Perfect The house has been destroyed by the soldiers.
Past Perfect The house had been destroyed by the
soldiers.
Future The house will be destroyed by the soldiers.
Future Perfect The house will have been destroyed by the
soldiers.

Only in the present and past tenses is there a difference between
the habitual form of the conjugation and the conjugation for an
action in progress or incomplete:
the house is destroyed/the house is being destroyed
the house was destroyed/the house was being destroyed
