Most English sentences are active
(they start with the doer of the
action) not passive (they start
with the receiver of the action).
Passive voice
• Passive voice is used when
the focus is on the action.
• When it is not so important
who did the action
• When the one who did the
action is unknown.
Example: My bike was stolen.
• In the example above, the focus is on the fact that
my bike was stolen. I do not know, however, who
did it.
To change from active to passive voice
follow these rules:
1- The object becomes subject.
2- Use verb to be in the tense of the active verb.
3- Use the past participle.
4- The subject becomes object and use (by) before it.
