Lí thuyết và bài tập vận dụng môn Tiếng Anh Lớp 7 - Passive Forms

PASSIVE FORMS
Thể bị động
I/- Thể bị động được sử dụng trong những trường hợp sau:
Khi chúng ta không biết ai đã thực hiện hành động hoặc cũng không quá quan trọng phải biết hành động đó được thực hiện bởi ai.
Ex: 	My briefcase was stolen last night. (I don’t know who stole it.)
Khi chúng ta nhấn mạnh vào bản thân hành động chứ không nhấn mạnh chủ thể gây ra hành động.
Ex: 	My hair is being done by the hairdresser.
II/- Cách chuyển từ câu chủ động (active) sang câu bị động (passive):
Lấy tân ngữ của câu chủ động làm chủ ngữ cho câu bị động
Động từ chính trong câu chủ động chuyển xuống thành quá khứ phân từ.
Trước quá khứ động từ ta thêm động từ tobe. (thì của động từ tobe phụ thuộc vào thì của động từ chính)
Khi muốn nhấn mạnh tác nhân (agent) gây nên hành động ta dùng by + agent. (chủ ngữ của câu chủ động chuyển xuống thành tân ngữ (O) cho câu bị động.
