Passive Voice
S V O
ACTIVE : (a) Mary helped the boy.
S V
PASSIVE : (b) The boy was helped by Mary
Form of the passive : be + past participle
In the passive voice, the object of an active verb becomes the subject of the passive verb: “the boy” in (a) becomes the subject of the passive verb in (b). (a) and (b) have the same meaning.
ACTIVE : (c) An accident happened.

Using Passive Voice
(a) Rice is grown in India.
(b) Our house was built in 1890.
(c) This olive oil was imported from Spain.
Usually passive voice is used without a “by phrase.” The passive is most frequently used when it is not known or not important to know exactly who performs an action.
In (a) : Rice is grown in India by people, by farmers, by someone. In sentence (a), it is not known or important to know exactly who grows rice in India.
(a), (b), (c) illustrate the most common use of the passive, i.e., without the “by phrase.”
(d) Life on the Mississippi was written by Mark Twain.
The “by phrase” is included only if it is important to know who performs an action. In (d), by Mark Twain is important information.
(e) My aunt made this rug. (active)
(f) This rug was made by my aunt.
(g) That rug was made by my mother.
If the speaker/writer knows who performs an action. Usually the active is used, as in (e).
The passive may be used with the “by phrase” instead of the active when the speaker/writer wants to focus attention on the subject of a sentence. In (f) the focus of attention is on two rugs.
