Passive Voice
Use:
Passive voice is used when the focus is on the action. It is not important or not known, however, who or what is performing the action. The passive voice is a grammatical construction (specifically, a "voice") in which the subject of a sentence or clause denotes the recipient of the action (the patient) rather than the performer (the agent). Passive voice is formed with an auxiliary verb (usually be or get) plus a participle (usually the past participle) of a transitive verb.
