Passive voice is not just "add was/were + past participle". Commands, verbs with two objects, and modals each transform in their own special way.

Commands turn passive using "Let" or "should be". Modal verbs keep the modal but change the main verb to its past participle.
📌 Two special passive patterns
Imperative (command): "Close the door" → "Let the door be closed." or "The door should be closed."
Request: "Please help me" → "You are requested to help me."
Modal verb: "You must finish the work" → "The work must be finished (by you)."

A verb like "give" or "teach" has TWO objects — that means it can usually form TWO different passive sentences, both correct.
📊 One active sentence, two passives
| Active | Passive (object 1) | Passive (object 2) |
|---|---|---|
| She gave me a book. | I was given a book. | A book was given to me. |
| The teacher taught us grammar. | We were taught grammar. | Grammar was taught to us. |
Agentless passive: when the doer is unknown, obvious, or unimportant, drop the "by" phrase entirely — "The window was broken" (not "…by someone"), or "Rice is grown in Punjab" (the farmers are obvious and unimportant here).
Achievers questions test the interrogative passive — turning a question into passive voice keeps the question word at the front.
🏆 The interrogative passive
Yes/No question: "Did she write this essay?" → "Was this essay written by her?"
Wh-question (object): "What did he break?" → "What was broken by him?"
Wh-question ("who" as subject): "Who wrote this essay?" → "By whom was this essay written?"
Pro tip: When "who" is the DOER in the active question, it becomes "by whom" in the passive — never just "who" left unchanged.
