GRAMMAR : PASSIVE VOICE
A. Revision: Passive Voice ( ôn tập về câu bị động)
-Câu bị động thường có cấu trúc sau:

ACTIVE: Graham Bell invented The telephone
S +
V +
O

PASSIVE: The telephone
S
+ V

was invented

BY Graham Bell

B. Những điều cần ghi nhớ khi đổi câu chủ động
(Active) sang câu bị động (Passive):
1. Lấy túc từ (Object) của câu chủ động làm chủ từ
(Subject) câu bị động.
2. Trong câu bị động, luôn phải dùng trợ động từ “Be” với
hình thức thích hợp tùy theo thì cần dùng.
3. Động từ chính (main verb) trong câu bị động luôn được
dùng ở dạng quá khứ phân từ (past participle)
4. Khi muốn nói thêm ai gây ra hành động,chúng ta có thể
dùng chủ từ câu chủ động làm “tác nhân” (Agent) câu bị
động và đứng sau “By”
5. Nhiều câu bị động không cần dùng “by” , tác nhân , nhất
là khi tác nhân là : “somebody, someone, people”, hoặc các
đại từ như “me, you , him , her , us , them”.

Ex: - The floor is cleaned every morning by someody
- Many new buildings have been built in recent years
by people
Tuy nhiên, tùy theo ý nghĩa đặc thù của câu nói, đôi
khi chúng ta phải dùng các tác nhân trên trong câu bị động
Ex: This program is being watched by millions of people.
C. Bảng đối chiếu hình thức thay đổi của trợ động từ
“BE” từ câu chủ động sang câu bị động.
