C. Passive Voice

1. Definition of Passive Voice

Talking about passive voice cannot be separated to talking about active voice because students should be encouraged to form passive voice from the active sentence given. Both sentences need transitive verbs to indicate them as a passive or active sentence. “Voice itself means the form of transitive verb takes to show whether the subject of the verb performs or receives the action.” 22 When the subject of a verb performs the action; it is called an active voice. Meanwhile, the subject which receives the action is called passive voice. The passive form allows people to focus on the action and the receiver of that action. In line with the above definition, passive voice is a sentence in which the verb indicates the object of the action or the effect of the verb. 23 In this case, students should understand which one as a subject or object in a sentence, either active or passive. As the following examples show subjects, verbs, and objects in active and passive voice. 22 John E. Warriner, Literature and Language Arts, Austin: HOLT, RINEHART, And WINSTON, 2009, p. 211. 23 Marcel Danesi, Basic American Grammar and Usage, New York: Barron’s, 2006, p. 171. Active Voice : My brother broke the mirror. S V O Passive Voice : The mirror was broken by my brother. S V O Active Voice : Dianne will invite Tom to her party. S V O Passive Voice : Tom will be invited by Dianne to her party. From the sentences above, it can be explained that, first, the object in active voice becomes the subject in the passive form. Second, the subject in active voice may become the one who receives the action begun with by. In active sentence, my brother is the focus idea, but in passive sentence, the mirror is the main point. To understand the passive form, students should know the grammatical term of subject, object, and transitive verb. The term ‘by-phrase’ is used for the prepositional phrase that includes the doer of the verb’s action. Yet, it sometimes does not require identification of the doer because it may not important or necessary to know who did something. 24 In summary, passive voice is a sentence in which it focuses on what happens to the subject whowhat gets the action, whereas an active voice shows the action of what subject does. In the passive voice, the subject of active sentence becomes the object of passive sentence.

2. Formula of Passive Voice

There are some rules to change an active sentence becomes passive voice. a. Students change the subject in active becomes the object in passive. So, the position of agent in active will be put after the verb which is preceded by ‘by’. 24 Martha Hall and Betty S. Azar, Understanding and Using English Grammar, New York: Pearson, 2010, 4 th Edition, p. 70.
