1. Khái niệm câu chủ động và bị động:
– Câu chủ động: Là câu có chủ ngữ là chủ thể tạo ra hành động. Câu chủ động được dùng khi chúng ta biết rõ chủ thể của hành động.
Ví dụ: People speak English all over the world.
– Câu bị động: Là câu có chủ ngữ là người hay vật chịu tác động của hành động. Câu chủ động được dùng khi ta không biết rõ chủ thể của hành động hoặc có biết nhưng người nói muốn nhấn mạnh tới đối tượng hơn tới chủ thể của hành động. Ví dụ: English is spoken all over the world.
Lưu ý: Không phải cứ chủ ngữ là người thì là chủ động, chủ ngữ là vật thì là bị động.
Ví dụ:
The students were punished yesterday.
Hanoi has changed a lot in the past five years.
2. Quy tắc chuyển câu chủ động sang câu bị động
*Quy tắc chung: To be + Past participle
- Xác định thì ngữ pháp của câu chủ động để tìm thể bị động tương ứng của nó.
- Xác định tân ngữ trong câu chủ động để rút về làm chủ ngữ trong câu bị động. Nếu câu có hai tân ngữ thì có thể chuyển thành hai câu bị động nhưng thông thường ta chọn tân ngữ chỉ người.
Simple present:
S + V (s/es) + Object
S + am/is/are + PII + by + O
Trong câu bị động, nếu tân ngữ không xác định (people, them, someone, him, her …) thì bỏ đi.
