Active to passive voice exercise worksheet for English grammar practice.

To convert active sentences into passive sentences, we need to follow these steps:

1. Identify the subject (the doer of the action) and the object (the receiver of the action).
2. Make the object the new subject of the sentence.
3. Use the appropriate form of the verb "to be" followed by the past participle of the main verb.
4. Optionally, include the agent (the original subject) using "by."
