To convert an active sentence to a passive sentence, you can follow these general rules:
1. Identify the subject, verb, and object of the active sentence.
- The subject is the doer of the action.
- The verb is the action being performed.
- The object is the receiver of the action.
2. Move the object of the active sentence to the subject position in the passive sentence.
- The object of the active sentence becomes the subject of the passive sentence.
3. Change the verb from active voice to passive voice.
- Use a form of the verb "to be" (such as "is," "are," "was," "were") followed by the past participle of the main verb.
- Adjust the verb tense if necessary.
4. Add the preposition "by" to indicate the doer of the action (optional).
- If it is important to mention who performed the action, you can include "by" followed by the doer of the action.
- However, in some cases, the doer may not be mentioned or known, and the "by" phrase can be omitted.
5. Make any necessary adjustments to the sentence structure and pronouns.
- Adjust pronouns and possessive determiners to match the new subject and object.
