Worksheet for practicing passive voice conversion from active voice in the present simple.

To change a sentence from active voice to passive voice, we follow these steps:
1. Find the object (the thing receiving the action) and move it to the front of the sentence. This becomes the new subject.
2. Change the verb. Since the original sentences are in the Present Simple tense, we use am, is, or are + the past participle of the verb (usually ending in -ed).
* Use is for singular subjects (he, she, it, one thing).
* Use are for plural subjects (we, they, multiple things).
3. Add "by" followed by the original doer of the action at the end. If the doer is vague (like "someone"), you can leave it out.
