sentence and the thing receiving the
action is the object. Most sentences

are active.

Passive voice

In passive sentences, the thing receiving the
action is the subject of the sentence and the

passive form if you think that the thing

be emphasized. You can also use the passive
form if you do not know who is doing the action

or if you do not want to mention who is doing
the action.
