Passive voice is used to stress the thing done by doer than the doer.

The change of tenses when a sentence is changed from active voice to passive voice :

2. Present continuous

Active : is / am / are baking

Passive : is / am / are being baked

Active : Write

Passive : Was / were written

4. Past continuous

Active : was / were watching

Passive : was / were being watched

5. Present Perfect

Active : have / has cleaned

Passive : have / has been cleaned

6. Past Perfect

Active : had read

Passive : had been read

7. Future simple

Active : will write
