|In the active voice, the subject of the sentence is the doer of the action and the direct object follows the verb. In the passive voice, the subject of the sentence is the receiver of the action. There is no direct object. The doer of the actions is expressed by a prepositional phrase or may not be expressed.|
Refer to the examples below:
The aunt sent a doll’s house. (The sentence is in the active voice in which the doer is the aunt and the direct object is the doll’s house.)
A doll was sent by the aunt. (The second sentence is in the passive voice because the receiver of the action is the subject which is the aunt. We do not have a direct object in this voice.)
Note that the object of the verb in the active voice becomes the subject wehen the verb is changed to passive voice. The verb in the passive voice remains the same tense in as the verb in the active voice. This is indicated by various forms of the helping verb be (am, is, are, was, were, will be, shall be, has been, etc.) Intransitive verbs have no voice because they have no direct object.
Very often some would prefer to use the active voice, however there are some specific reasons why sometimes we also have to use the passive voice and the reasons are the following:
1. the action expressed is more important than the doer.
All the rooms were prepared. (In this example, the action of preparing the room was given more emphasis)
The carpenter prepared all the rooms. ( This sentence is in the active voice and the emphasis is more on the subject rather than the action made by the doer.
2. The speaker wants the statement to be impersonal, objective, or tactful
Children are affective by the war in Marawi. (This sentence would tell us that the War in Marawi affects the children. The emphasis is on the action.
3. The doer of the action is vague or unknown
The line of social distinction is drawn at the Kelveys. (The doer of the action is not mentioned in the sentence)
4. The action of the doer is confidential
He was reported to have taken the money. (The doer of the action is not specified to keep the confidentiality.
The above mentioned reasons are very helpful as guidelines to follow if we are to put emphasis on the action rather than the doer, then the passive voice is the perfect voice to use to make a sentence.
