What are the different tenses that can be used in passive voice?

In passive voice, the subject of the sentence receives the action rather than performing it. The different tenses that can be used in passive voice are as follows:

1. Present Simple Passive: This tense is formed by using the auxiliary verb "is/are/am" + past participle of the main verb. For example, "The cake is baked by my mother."

2. Past Simple Passive: This tense is formed by using the auxiliary verb "was/were" + past participle of the main verb. For example, "The letter was written by John."

3. Present Continuous Passive: This tense is formed by using the auxiliary verb "is/are/am" + being + past participle of the main verb. For example, "The house is being painted by the workers."

4. Past Continuous Passive: This tense is formed by using the auxiliary verb "was/were" + being + past participle of the main verb. For example, "The car was being repaired by the mechanic."

5. Present Perfect Passive: This tense is formed by using the auxiliary verb "has/have been" + past participle of the main verb. For example, "The book has been read by many people."

6. Past Perfect Passive: This tense is formed by using the auxiliary verb "had been" + past participle of the main verb. For example, "The project had been completed before the deadline."

7. Future Simple Passive: This tense is formed by using the auxiliary verb "will be" + past participle of the main verb. For example, "The concert will be attended by thousands of fans."

8. Future Perfect Passive: This tense is formed by using the auxiliary verb "will have been" + past participle of the main verb. For example, "By next year, the new building will have been constructed."

These are the different tenses that can be used in passive voice, allowing us to express actions or events in various time frames while emphasizing the receiver of the action rather than the doer.
