PASSIVE VOICE
CÁCH CHUYỂN ĐỔI TỪ CÂU CHỦ ĐỘNG SANG CÂU BỊ ĐỘNG
Các bước đổi từ câu chủ động sang câu bị động:
Bước 1: Xác định thành phần câu: chủ ngữ (subject = S), động từ (Verb = V), tân ngữ (Object = O)
Bước 2: Xác định thì (tense) dạng (form) của động từ để xác định thì dạng của động từ “to be”
Bước 3: Xác định quá khứ phân từ (past participle = pp = V3ed )
Bước 4: đổi theo thứ tự
Lấy tân ngữ đổi thành chủ ngữ O ( S
Subject
I
WE
YOU
HE
SHE
IT
THEY
NOUN
WHO

Object
ME
US
YOU
HIM
HER
IT
THEM
NOUN
WHOM


Chia động từ “to be” theo thì dạng của động từ chính.
Đổi động từ chính thành quá khứ phân từ V3ed
Lấy chủ ngữ đổi thành “by + tân ngữ” (by + O)
 A: S + V + O

P: S + BE + V3ed + by O

(Chia thì theo động từ của câu Active)
Ex: Active: Susan wrote a letter.
      Passive: A letter was written by Susan.
      Active: He has bought some books.
     Passive: Some books have been bought (by him).
