Using the active voice, you concentrate on the person or thing carrying out the action.
Examples:
Jenny closes the door.
Kevin hits Tom.
Using the passive voice, you concentrate on the person or thing affected by the action.
Examples:
The door is closed by Jenny.
Tom is hit by Kevin.
As you can see, an important part of the passive is the past participle.
When employing regular verbs, you just have to add ‘–ed’ to the infinitive.
Examples:
to close – closed, to call – called, to cook – cooked
When employing irregular verbs, you take the past participle – usually the third form listed.
Examples:
to write – written, to take – taken, to bring – brought
Another element is the verb ‘to be’ in the right tense.
So: [size=150][color=blue]passive voice = person or thing affected + to be + past participle (+ by performer)[/size]
