II. CÁCH ĐỔI ACTIVE VOICE SANG PASSIVE VOICE:
Ex: Active sentence: Peter took this book yesterday
Passive sentence: This book was taken by Peter yesterday
Trong câu chủ động:
- Peter → Subj ; took → động từ chính (Past simple)
- this book → Obj; yesterday → trạng từ chỉ thời gian
Trong câu bi động:
- Obj ( this book) → Subj ; Subj ( Peter) →by Obj
- took (động từ chính) → taken (V3 / VoED - Past participle)
- thêm was vì động từ chính (took) đang chia thì Past simple
A. Tổng quát:
A. Tổng quát:
active sentence:
Subject + V +
Obj
Passive sentence:
Subject + BE + V3 / VED (động từ chính) + by Obj

1- Chuyển: Obj ---> Subj; Subj ----> by Obj (Có thể bỏ nếu by Obj không cần thiết)
2-Thêm BE và chia thì tương ứng với thì câu chủ động.
Nghĩa là: Động từ chính của câu chủ động ở thì nào thì “ To Be” phải chia ở thì đó). Như
vậy: trong câu bị động “ To Be” có vai trò chia thì, Động từ chính có chức năng như một
tính từ mang nghĩa bị động (không chia thì)
3- Chuyển động từ chính sang ---> V3 hoặc Vo ED.
B. Cụ thể như sau:

động từ chính của câu chủ động)

: nếu không cần thiết).
- Nếu Subj của câu chủ động là danh từ chỉ vật liệu, dụng cụ ---> câu bị động thay by bằng
with + Obj.
Ex: Moss is covering this wall. ---> This wall is being covered with moss.
- Nếu Subj của câu chủ động là: nothing, no one, nobody ---> câu bị động bỏ by Obj và ở
thể phủ định.
Ex: No one helps me ---> I am not helped.
3. Chuyển động từ chính sang ---> V3 hoặc Vo ED.
(Động từ chính có chức năng như một tính từ mang nghĩa bị động-không chia thì)
4. Thêm BE và chia tương ứng với thì của câu chủ động (Động từ chính của câu chủ động ở thì
nào thì To be phải chia ở thì đó )
5. Giữ lại động từ khiếm khuyết (Modal verb) trong câu bị động nếu có.
Will/ would, shall/ should, can/ could, may/might must, have to, be going to, used to, ...
