Active to Passive Voice Worksheet for Students

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.
2. Change the verb. You need to use the helping verb "to be" in the same tense as the original sentence, followed by the past participle of the main verb (usually ending in -ed).
3. Add the subject (the doer) at the end using "by." If the subject is general (like "they," "people," or "someone"), you can often leave it out.

1. Active: The teacher praised the students.
