Explain the formation of the passive voice in the present simple and past simple tenses, providing examples.

  • Example 2: "These books are collected by the students every week." (The books receive the action of collecting.)

• Past Simple Passive The rule for forming the past simple passive is to use was or were followed by the past participle (p.p.) of the main verb.

  • Example 1: "Many houses were destroyed by the floods last year." (The houses received the action of being destroyed.)
  • Example 2: "The factory was founded by government a year ago." (The factory received the action of being founded.)
