Active and Passive Voice Voice The voice of a verb tells whether the subject of the sentence performs or receives the action. In English there are two voices, passive and active. Active Voice In active voice, the subject performs the action expressed by the verb: The student wrote a song. Passive Voice In passive voice, the subject receives the action expressed by the verb: A song was written by the student.

Changing a sentence from the active voice to the passive voice involves 3 steps: 1. move the direct object to the subject of the sentence. 2. move the subject to the end of the sentence; add the preposition "by" before it. 3. change the verb.
Changing the verb involves three steps: 1. check the verb tense; use the verb “be” in the same tense; 2. change the verb into a past participle; put this verb after the form of “be”; 3. check that the new verb goes with the new subject.
