PASSIVE FORMS
I. DEFINITION (Định nghĩa)
- Câu bị động là câu có chủ ngữ là người hoặc vật chịu/nhận hành động của một tác nhân khác. (là đối tượng của hành động)
e.g1: I am taken to school every morning by my father.
(Chủ ngữ trong ví dụ trên là đại từ “I”, “tôi” không phải là chủ thể của hành động “đưa đến trường” mà là người được đưa đến trường (tân ngữ) bởi “bố tôi”.
e.g2: A letter is being written now by Lan.
(Chủ ngữ trong ví dụ trên là danh từ “A letter”, “lá thư” không phải là chủ thể của hành động “đang viết” mà là vật đang được viết (tân ngữ) vào lúc này bởi bạn Lan).
- Câu chủ động là câu có chủ ngữ là người hoặc vật là chủ thể của hành động, trạng thái được diễn đạt bởi động từ.
e.g1: Lan is writing a letter now.
(Chủ ngữ trong câu trên là danh từ “Lan”, Lan chính là người đang thực hiện hành động viết thư vào lúc này).
e.g2: My father takes me to school every morning.
(Chủ ngữ trong câu trên là danh từ “My father”, “bố tôi” chính là người thường thực hiện hành động đưa tôi đến trường vào các buổi sáng).
II. FORM (Công thức thành lập)
Cụ thể:
- Để thành lập câu bị động chúng ta sử dụng dạng đúng của động từ “to be” và quá khứ phân từ của động từ chính “past participle”.
III. USE:
- Câu bị động được sử dụng để nhấn mạnh vào hành động.
e.g1: English is spoken in many countries.
- Câu bị động cũng được sử dụng khi người nói/viết không biết hoặc muốn đề cập tới chủ thể của hành động.
e.g2: The cup has been broken.
IV. HOW TO CHANGE THE ACTIVE IN TO THE PASSIVE (Cách chuyển một câu chủ động sang câu bị động)
- Chúng ta chỉ có thể chuyển một câu chủ động sang câu bị động nếu câu đó có tân ngữ (nói cách khác động từ chính trong câu phải là ngoại động từ). Và một câu có bao nhiêu tân ngữ thì có thể chuyển thành bấy nhiêu câu bị động.
- Để chuyển một câu chủ động sang câu bị động chúng ta thực hiện theo 3 bước sau:
+ Bước 1: Xác định tân ngữ (người hoặc vật chịu/nhận tác động của chủ từ) bằng cách đặt câu hỏi “Chủ ngữ trong câu tác động lên người hay vật nào ?” hoặc “Người hay vật nào phải chịu tác động của chủ từ trong câu ?”).
+ Bước 2: Rút tân ngữ vừa xác định được ra và đưa lên làm chủ ngữ mới của câu bị động).
+ Bước 3: Chia động từ theo mẫu (Sử dụng dạng đúng của trợ động từ “to be” và quá khứ phân từ của động từ chính “past participle”).
e.g1: Nam bought me a watch on my birthday.
(Trong câu trên có hai tân ngữ là “me” và “a watch”, do đó mà chúng ta hoàn toàn có thể chuyển câu trên thành 2 câu bị động như sau:
I was bought a watch on my birthday by Nam.
A watch was bought for me on my birthday by Nam.
e.g2: I’ll see a movie tonight.
A movie will be seen tonight by me.
* Nếu muốn nêu rõ chủ thể của hành động chúng ta dùng cụm từ “by + agent”.
e.g3: I am taken to school every morning by my parents.

VI. PASSIVE FORMS OF SOME SPECIAL STRUCTURES:
1. Passive form of modal verbs:
Modal verb + be + past participle. |
e.g1: I can sing English songs. (active)
→ English songs can be sung by me. (passive)
e.g2: You must do your homework regularly. (active)
→ Your homework must be done regularly. (passive)
2. Past passive form of modal verbs:
modal verb | have been | past participle. |
e.g1: We should have invited Linda.
Linda should have been invited (by us).
e.g2: You must have eaten fish for dinner.
Fish must have been eaten for dinner (by you).
3. Stative passive:
e.g1: I am tired of reading the same book every day.
e.g2: They are married.
- Qua 2 ví dụ trên chúng ta có thể thấy là câu bị động trạng thái (Stative passive) cũng được thành lập giống với các câu bị động thông thường khác đó là:
- Tuy nhiên quá khứ phân từ ở đây không diễn tả hành động của chủ thể mà chúng diễn tả trạng thái của chủ thể, do đó chúng có chức năng như một tính từ.
- Theo sau quá khứ phân từ trong câu không phải là cụm từ “by + agent” mà thay vào đó là giới từ nếu có.
- Dạng câu bị động này (Stative passive) không có câu chủ động tương đương.
- Đôi khi chúng ta cũng có thể dùng “get” để thay thế cho “be”.
e.g3: She got married to a foreigner last year.
4. Passive form of verbs followed by a gerund:
- Để thành lập câu bị động với các động từ được theo sau bởi một danh động từ chúng ta sử dụng hiện tại phân từ của động từ “to be” (là “being”) và kết hợp quá khứ phân từ của động từ chính.
| like | being | past participle. |
| dislike |
| love |
| enjoy |
| ... |
e.g1: I dislike people telling me what to do.
→ I dislike being told what to do.
e.g2: She loves people admiring her.
→ She loves being admired.
5. Passive form of “need” and “want”:
- Để thành lập câu bị động với “need” và “want” chúng ta có thể làm theo hai cách sau:
Cách 1: Sử dụng hiện tại phân từ của động từ chính.
| need | present participle |
| want |
e.g1: Your hair is too long. It needs cutting.
e.g2: The car is too dirty. It wants cleaning.
Cách 2: Sử dụng “to be” kết hợp với quá khứ phân từ của động từ chính.
| need | to be | past participle |
| want |
e.g3: His coat is too dirty. It needs to be cleaned.
e.g4: Their house is too old. It wants to be repaired.
6. Passive forms of “make”
- Lưu ý ở dạng chủ động ta có mẫu câu:
Make sb do st: bắt/bảo ai đó (phải) làm gì đó.
- Nhưng khi chuyển sang dạng thụ động ta có mẫu câu sau:
Be made to do st: bị ép/bắt làm gì đó.
e.g1: She usually makes me do the housework.
→ I am usually made to do the housework.
e.g2: They made him work hard from morning till night.
→ He was made to work hard from morning till night.
7. Passive forms of “let”:
- Lưu ý ở dạng chủ động ta có mẫu câu:
Let sb do st: cho phép ai đó làm gì.
- Nhưng khi chuyển sang dạng thụ động ta có mẫu câu sau:
Be let to do st: được phép làm gì. (Hoặc là: be allowed to do smt.)
e.g1: He let me play video games once a day.
→ I’m let to play video games once a day. (I’m allowed to play …)
8. “Have something done” và “Get something done”:
- Các mẫu câu này được sử dụng để diễn đạt ý “chủ ngữ trong câu không thực hiện hành động mà thuê/mướn/bảo ai đó thực hiện hành động cho mình.”
- Hai dạng chủ động và bị động cụ thể như sau:
Active | Passive |
S + have someboby do something. e.g1: I had a mechanic repair my car. | S + have something done. I had my car repaired (by a mechanic). |
S + get somebody to do something. e.g2: He gets a barber to cut his hair once a day. | S + get something done. He gets his hair cut once a day. |
e.g3: I had my hair cut. (passive)
e.g4: I cut my hair. (active)
9. Impersonal passive:
- Một số động từ hay dùng: know, say, think, report, rumour, believe.
e.g1: People think that he is a liar. (active)
→ It’s thought that he is a liar. (passive)
→ He is thought to be a liar. (passive)
e.g2: People thought that she passed the exam. (active)
→ It was thought that she passed the exam. (passive)
→ She was thought to have passed the exam. (passive)
- Quy tắc chuyển từ câu chủ động (active) sang câu bị động (pasive): có 2 cách.
* Cách 1: Mượn đại từ “It” làm chủ ngữ của câu bị động đồng thời kết hợp với dạng đúng của trợ động từ “to be” và quá khứ phân từ của động từ chính. Sau đó kéo nguyên mệnh đề với “that” (that clause) xuống cuối câu.
It + be + past participle + that clause. |
e.g1: People say that I am not qualified for that job.
→ It’s said that I am not qualified for that job.
e.g2: People said that they got divorced last year.
→ It was said that they got divorced last year.
* Cách 2: Lấy chủ ngữ trong mệnh đề với “that” (that clause) ra làm chủ ngữ của câu bị động đồng thời sử dạng đúng của trợ động từ “to be” và quá khứ phân từ của động từ chính kết hợp với động từ trong mệnh đề với “that” (that clause) theo 2 dạng sau:
S + be + past participle | to do smt. |
to have done smt. |
- Chúng ta sử dụng dạng “to do smt” sau quá khứ phân từ của động từ chính khi động từ trong mệnh đề “that” được sử dụng ở thì hiện tại/tương lai đơn.
e.g1: People rumour that she speaks English perfectly.
→ She is rumoured to speak English perfectly.
- Chúng ta sử dụng dạng (to have done smt” sau quá khứ phân từ của động từ chính khi động từ trong mệnh đề “that” được sử dụng ở thì quá khứ đơn hoặc hiện tại hoàn thành.
e.g2: People rumour that she spoke English perfectly.
→ She is rumoured to have spoken English perfectly.
