  Active: Don't touch this.       Passive: Let this not be touched.
  Active: Please help me.         Passive: You are requested to help me.

─── Questions in Passive ───
  Active: Did she finish the work?
  Passive: Was the work finished by her?

  Active: Who wrote this letter?
  Passive: By whom was this letter written?

─── Ditransitive Verbs (two objects) ───

  Passive 2: A book was given to me by him. (thing as subject)

  When the doer is unknown, obvious, or unimportant:
    "The window was broken." (don't know who broke it)

    "The thief was arrested." (by the police — obvious)

─── Cannot Be Made Passive ───
  - Intransitive verbs (verbs without object):
    "He sleeps." (NO passive — "is slept" is wrong)
    "She arrived." (NO passive)
  - State verbs: belong, have, lack, resemble, suit
    "This book belongs to me." (NO passive — "is belonged" is wrong)

💡

Voice Conversion Tip: When converting active to passive, the tense NEVER changes — only the structure changes. The "be" verb in passive always matches the tense of the active verb. Remember: "be" + V3 = passive in any tense.

"The" — unique/specific things	Use for things that are one of a kind or already known	the sun, the moon, the longest river, the Himalayas, the Pacific Ocean
