`@` Câu bị động thì QKTD:

`+)` S + was/were + being + Vpp + (by O)

`-)` S + was/were + not + being + Vpp + (by O)

`?)` Was/were + S + being + Vpp + (by O)?

`@` Câu bị động thì HTHT:
`+)` S + has/have + been + Vpp + (by O)

`-)` S + has/have + not + been + Vpp + (by O)

`?)` Has/have + S + been + Vpp + (by O) ?

`@` Chú ý: 

- Trạng từ chỉ thời gian đứng sau by O , trạng từ chỉ nơi chốn đứng trước by O.

- Nếu ở câu bị động chủ ngữ là they , people , some one , sombody , something , no thing , no one , ... thì khi chuyển về câu bị động không dùng by O.

- Nếu ở câu bị động chủ ngữ là we , he , she , you , ... thì khi chuyển về câu bị động có thể dùng hoặc không dùng by O tùy vào ngữ cảnh.
