To change a sentence from active voice to passive voice, we follow these steps:
1. Move the object (the thing receiving the action) to the front of the sentence. This becomes the new subject.
2. Add the verb "to be" in the present simple tense (am, is, or are) depending on whether the new subject is singular or plural.
3. Change the main verb to its past participle form (usually ending in -ed, but some are irregular like *written*, *caught*, *broken*).
4. Add "by" followed by the original doer of the action at the end (optional if the doer is unknown or unimportant, but usually included in these exercises).
