THANKS FOR YOUR ATTENTION!
Notes: 1. Ta có thể bỏ:by me/him/her/it/us/you/ them/somebody/someone/nobody/noone/everybody/everyone/people trong câu bị động nếu không muốn nêu rõ tác nhân hoặc thấy không quan trọng.





2. Nếu câu chủ động có trạng từ (ngữ), hoặc cụm trạng từ chỉ thời gian thì đặt chúng sau “by + O (bị động)”
Notes: 3. Nếu V chủ động có 2 O thì một trong 2 O có thể làm S trong câu bị động (nhưng S về người được sử dụng nhiều hơn). Nhưng thông thường chủ ngữ hợp lí của câu bị động là tân ngữ gián tiếp.
4. Các Verbs: ask, tell, give, send, show, teach, pay, offer thường có 2 tân ngữ.
5. Nếu câu chủ động có các trạng từ (ngữ) chỉ nơi chốn thì đặt chúng trước “by + O (bị động)”.
