(THE PASSIVE VOICE)
* Thể chủ động (active voice) là cách đặt câu mà chủ từ đóng vai trò chủ động.
- Mr Brown wrote the report yesterday.
- He has already finished his homework.
* Thể thụ động (passive voice) là cách đặt câu mà chủ từ đóng vai trò bị động.
- That house was built 100 years ago.
- Those windows are painted blue.
Passive sentence : S + be + past participle
1/ Hãy quan sát ví dụ sau :
* Active : Tom broke the chair yesterday.
* Passive : The chair was broken by Tom yesterday.
2/ Ghi nhớ: Cách đổi một câu từ active sang passive :
* Lấy túc từ (O) trong câu chủ động xuống làm chủ từ (S) trong câu thụ động
* Nhận xét xem động từ chia trong câu chủ động ở thì nào, ta chia TO BE ở thì đó rồi viết động từ chính ở dạng quá khứ phân từ (p.p)
* Lấy chủ từ (S) trong câu chủ động xuống làm doer trong câu thụ động, nhớ viết BY ngay đằng trước
* Trạng từ giữ nguyên không đổi và thường đặt cuối câu (nếu là trạng từ chỉ thời gian)
