LEARN THIS! The passive
1 We form the passive with the verb 1 to be and the 2 past participle of the main verb. The object of an active verb can become the 3 subject of a passive verb.
They haven't found a cure for colds yet. (a cure = object)
→ A cure for colds hasn't been found yet. (a cure = subject)
2 If we need to mention the agent, we use 4 by
Enormous public baths were built by the Romans.
3 We use the passive:
a when we do not know (or do not want or need to say) who does something.
b for more formal language, e.g. for processes.
First, the coffee beans are dried. Then they are roasted
c when we want to focus on the person to whom the action is done, not the person doing the action.
4 We use the 5 simple and past continuous forms of the passive, but we do not use other continuous forms.
Hygiene is being improved.✔
→ Hygiene has been being improved. X
→ They have been improving hygiene.✓

LEARN THIS! Bị động
1 Chúng ta tạo thành thể bị động với động từ to be và phân từ quá khứ của động từ chính. Tân ngữ của động từ chủ động có thể trở thành chủ ngữ của động từ bị động.
Họ vẫn chưa tìm ra cách chữa cảm lạnh. (một phương pháp chữa trị = tân ngữ)
→ Thuốc chữa cảm lạnh vẫn chưa được tìm ra. (một cách chữa trị = chủ ngữ)
2 Nếu cần đề cập đến tác nhân, chúng ta dùng by
Những nhà tắm công cộng khổng lồ được xây dựng bởi người La Mã.
3 Chúng ta sử dụng thể bị động:
a khi chúng ta không biết (hoặc không muốn hoặc không cần nói) ai làm việc gì đó.
b cho ngôn ngữ trang trọng hơn, ví dụ: cho các quá trình.
Đầu tiên, hạt cà phê được sấy khô. Sau đó chúng được nướng
c khi chúng ta muốn tập trung vào người thực hiện hành động chứ không phải người thực hiện hành động đó.
4 Chúng ta sử dụng dạng đơn và quá khứ tiếp diễn của thể bị động, nhưng chúng ta không sử dụng các dạng tiếp diễn khác.

→ Vệ sinh đã được cải thiện. X
