·Cấu trúc khẳng định:
S + had + V3 + O
Ex: I had visited this museum when they invited me.
·Cấu trúc phủ định:
S + hadn't + V3 + O
Ex: He hadn't slept last week.
·Cấu trúc nghi vấn:
Had + S + V3 + O + ?
Ex: Had you loved him?
·Cấu trúc từ WH:
Wh-words + had + S + V3 + O +?
Ex: What had they gifted for your birthday?

2. Chuyển sang bị động
Sample Sentence: They are going to organize a garden party to raise money for the victims of the flood
Passive voice: The victims of the flood is going to be organized a garden party to raise money.
*Explaination: Dùng câu bị động ở dạng thì tương lai gần
*Cấu trúc: S + be (am/is/are) + going to be + $V_{0}$ + O
