The document provides examples of sentences using passive and active voice. In the passive voice, the subject receives the action while in the active voice, the subject performs the action. Some examples given are: "The car was washed. He washed the car." showing the same event in both voices. And "The milk was drunk by the cat. The cat drank the milk." again demonstrating the equivalent active and passive constructions. The document also lists some regular and irregular verbs to illustrate differences in their past tense forms like "sing" becoming "sang" in the past.
