It shows whether the subject of a sentence is doing the action, or having the action done to it.ACTIVE VOICEThe verb is in the active voice when the subject does the action.Example: A cat ate the fish. (Subject: cat / Verb: ate / Object: fish)Here, the doer of the action is a cat and the verb "ate" is in the active voice. PASSIVE VOICEWhen action is done to the subject, the verb is in the passive voice. The previous object (fish) is now used as the subject.Example: The fish was eaten by a cat. (Verb: eaten / Subject: fish)Here, action is done to the subject and the verb "was eaten" is in the passive voice. Use of the Passive VoiceWe use the active voice whenever we can. We use the passive when:we want to make the active object more importantwe do not know the active subjectwe prefer not naming subjectverbobjectgive importance to active object President Kennedywas killedby Lee Harvey Oswald.active subject unknownMy wallethas been stolen.?when we choose not to name the one who performs the actionThe workwas done poorly.?Note that we always use by to introduce the passive object Example: Fish are eaten by cats. We use 'by' only when we have to.</li></ul>VERBS WITH TWO OBJECTS<br />A verb can have two objects – a person and a thing. Such a verb can have two possible passive voices.Example 1:Active: The salesman shows Nick a new computer. / The salesman shows a new computer to Nick.Passive: Nick is shown a new computer. / A new computer is shown to Nick.Example: 2:Active: We lent Bob some money. / We lent some money to Bob.Passive: Bob was lent some money. / Some money was lent to Bob.<br />CHANGING ACTIVE TO PASSIVE<br />In changing a sentence from active voice to one in the passive voice, we make the object of the active voice sentence the subject of the passive voice sentence. <br />The verb used in a passive voice sentence is formed by adding the past participle to quot;
(am, is, are, was, were, has been, have been, will be, etc.) <br />Passive verbs have the same tenses (simple present tense, present continuous tense, present perfect tense, etc.) as active verbs.<br />Only verbs which take on an object can be changed to the passive. <br />Example: He runs away. (This sentence has no object, so it's not possible to turn it into a passive sentence.)<br />Here are examples of sentences in active voice and passive voice in the present tense.<br />Present TenseActivePassivePresent SimpleWe make butter from milk.Somebody cleans these rooms every day.People never invite me to parties.How do they make butter? Butter is made from milk.These rooms are cleaned every day.I am never invited to parties.How is butter made?Present ContinuousThey are building a new airport at the moment. (= it isn’t finished)They are building some new houses near the river.A new airport is being built at the moment.Some new houses are being built near the river.Present PerfectLook! They have painted the door.These shirts are clean. Somebody has washed them.Somebody has stolen my car.Look! The door has been painted.These shirts are clean.
