Explanation of Conversion Rules
To change from passive to active voice, follow these steps:
1. Identify the Subject, Verb, and Object: In passive voice, the subject performing the action is often preceded by "by." Here:
· Passive Subject: "About 200 birds"
· Passive Object: "City Council"
· Verb: "were driven out"
2. Switch the Subject and Object: In active voice, the original object "City Council" becomes the subject, while "200 birds" becomes the object.
3. Adjust the Verb Form: In passive, "were driven" indicates a past action. In active voice, the verb becomes "drove" to indicate the same past action directly.
Structure of Passive and Active Voice in Past Simple
· Passive Voice Structure (Past Simple): Object + was/were + past participle of the verb + by + subject
· Example: About 200 birds were driven out by the City Council.
· Active Voice Structure (Past Simple): Subject + past form of the verb + object
· Example: The City Council drove out about 200 birds.
Applying These Rules:
Passive Voice: About 200 birds were driven out of their habitats by the City Council based on a Health Department recommendation. Active Voice: The City Council drove about 200 birds out of their habitats, based on a Health Department recommendation.
