form: to be + past participle Changing from Active into Passive
To change a sentence from the active into the passive:
nbsp; nbsp; The object of the active sentence becomes the subject of the passive sentence.
nbsp; nbsp; The active verb remains in the same tense but changes into a passive form.
nbsp; nbsp; The subject of the active sentence becomes the agent and is either introduced with by or is omitted if it is not a specific person or it is not essential to the meaning of the sentence.
Use
We use the passive: to give emphasis to the action rather than the person
who did it. The new theatre will be opened tomorrow by the Mayor. When the person who does the action is unknown, unimportant or obvious from the context.
