1) Form of Passive Cấu trúc câu bị động:

Subject + finite form of to be + Past Participle

(Chủ ngữ + dạng của động từ “to be” + Động từ ở dạng phân từ 2) Example: A letter was written.

Khi chuyển câu từ dạng chủ động sang dạng câu bị động:

Tân ngữ của câu chủ động chuyển thành chủ ngữ của câu bị động. Ví dụ: Active: He punished his child. -> Passive: His child was punished. (Anh ta phạt cậu bé.) (Cậu bé bị phạt)

Câu chủ động ở dạng thì nào, chúng ta chia động từ “to be” theo đúng dạng thì đó. Chúng ta vẫn đảm bảo nguyên tắc chủ ngữ số nhiều, động từ “to be” được chia ở dạng số nhiều, chủ ngữ số ít thì động từ “to be” được chia ở dạng số ít.

S + wish + thì quá khứ .

Eg : I wish I knew the answer to this question. (at present i don't know the answer)

2. Wish ở quá khứ

Để diễn đạt một mong muốn ở quá khứ, chúng ta dùng:
S + wish + The Past perfect.

3. Wish ở tương lai

+ Chúng ta có thể dùng "could" để diễn đạt mong muốn về một việc nào đó ở tương lai.

+ Chúng ta cũng có thể cùng "could" để diễn tả một việc nhìn chung rất khó có thể thực hiện, không khả thi.
Eg : I wish I could contact him, but I don't have my mobile phone with me.

+ Chúng ta cũng có thể dùng "have to" để nói về mong muốn một việc trong tương lai
