3. Chủ ngữ của câu chủ động thành tân ngữ của câu bị động và đứng trước nó là giới từ by. (BY+O)
Ví dụ: The mouse was eaten by the cat.

· Chủ ngữ I, you, we, they, he, she , it, one, people, someone, somebody, nobody, no one thường được bỏ đi trong câu bị động.
Ví dụ: Somebody left this purse in a classroom
àThis purse was left in a classroom

· Nếu trong câu chủ động có chủ ngữ là nobody , no one hay nothing thì động từ trong câu bị động chia ở dạng phủ định
Ví dụ: Nobody saw him leaving the room.
==>He wasn't seen leaving the room
· Nếu vật gián tiếp gây ra hành động ta có thể dùng with thay cho by để chỉ phương tiện thực hiện hành động.
Ví dụ: The bird was shot by the hunter
The bird was shot with the gun.
He was hit by the stone (It was an accident)
He was hit with the stone (Someone used a stone to hit him )
Các động từ dùng với with thay cho by : crowd (ngăn cản),fill(đổ đầy),cover(bao phủ) ,edge (viền ) , pack ( gói ) , stuff( nhồi ) ,pile ( chất đống ) , load ( chất )

* Vị trí của các trạng từ trong câu bị động :
· Trạng từ chỉ cách thức (Adverb of manner) thường đứng giữa be và past participle. Các trạng từ khác thường đứng sau trợ động từ đầu tiên.

Ví dụ: This problem have been carefully studied by scientists
She had never been promoted if she wouldn’t have changed her job

  • Trạng từ chỉ nơi chốn + By O + Trạng từ chỉ thời gian
Ex : The report was typed by the secretary this morning.
He was found in the forest by the police.
The books are arranged on the shelves (by her) every weekend.
