Passive Voice Error Correction

This passive voice error correction exercise targets the mistakes learners make when proofreading full passive sentences: using the wrong form of be, dropping been or being, and using a past simple verb instead of a past participle.

Wrong: "The reports was sent yesterday." Correct: "The reports were sent yesterday."
Wrong: "The shop is cleaned at the moment." Correct: "The shop is being cleaned at the moment."

Because this page asks you to edit only the wrong chunk inside each full sentence, it trains proofreading after normal passive voice transformation practice. Some sentences are already correct, so the task is not just to add passive forms everywhere. You must decide whether the sentence needs is/are, was/were, been, being, a past participle, or no change at all. That makes the route especially useful for learners who can form passive sentences in gap-fill tasks but still miss small auxiliary errors when reading real sentences.
