4. Động từ thường chia ra làm hai loại: nội động từ (intransitive verbs) và ngoại động từ (transitive 
verbs)

4.1. Nội động từ

• Nội động từ diễn tả hành động nội tại của người nói hay người thực hiện hành động.
Ví dụ:

- He walks. (Anh ấy đi bộ - Anh ấy tự đi chứ không phải là do người hay vật khác tác động)
- Birds fly. (Chim bay - Con chim tự bay theo bản năng chứ không do người hay vật tác động)

• Nội động từ khơng cần có tân ngữ trực tiếp đi kèm. Nếu có thì phải có giới từ đi trước và cụm từ này sẽ đóng vai
trị ngữ trạng từ chứ không phải là tân ngữ trực tiếp.

Ví dụ:

- She walks in the garden.
- Birds fly in the sky.
4.2. Ngoại động từ

• Ngoại động từ diễn tả hành động gây ra trực tiếp lên người hoặc vật.
Ví dụ: The cat killed the mouse.

• Ngoại động từ ln cần thêm yếu tố bên ngoài là một danh từ hay đại từ theo sau để hoàn thành nghĩa của câu.
Danh (đại) từ đi theo sau ngoại động từ là tân ngữ trực tiếp.

Trong câu trên chúng ta khơng thể nói “The cat killed” rồi dừng lại được mà phải có “the mouse” đi kèm theo sau.
“The mouse” là tân ngữ trực tiếp của “killed”.

4.3. Chú ý:

- Sự phân chia nội động từ và ngoại động từ chỉ là tương đối, vì trong câu này, động từ ấy là nội động từ nhưng
trong câu khác nó lại là ngoại động từ. Xem xét những ví dụ sau:

- The door openned. (Cửa mở) - nội động từ

She opened the door. (Cô ấy mở cửa) - ngoại động từ
- The bus stopped. (Chiếc xe buýt dừng lại) - nội động từ

The driver stopped the bus. (Tài xế dừng xe buýt lại) - ngoại động từ
- The bell rings. (Chuông kêu) - nội động từ

He rings the bells. (Ơng ấy rung chng) - ngoại động từ
- The glass broke. (Cốc vỡ) - nội động từ

The boy broke the glass. (Cậu bé làm vỡ cốc) - ngoại động từ

- His lecture began at 8pm. (Bài giảng của ông ta bắt đầu lúc 8h tối) - nội động từ
He began his work at 8pm. (Anh ấy bắt đầu công việc lúc 8h tối) - ngoại động từ

Thể của

động từ

I. Thể chủ động: Là cách đặt câu trong đó chủ ngữ đứng vai chủ động, chủ thể của hành động.
Ví dụ:+ She learns Chinese at school

+ She bought a book.

II. Thể bị động: Câu bị động được dùng khi muốn nhấn mạnh đến đối tượng chịu tác động của hành 
động hơn là bản thân hành động đó. Thời của động từ ở câu bị động phải tuân theo thời của động từ ở
câu chủ động.

• Sau đây là bảng tóm tắt:

Thì Dạng bị động

The simple present tense Is/ am/are + P2

The present progressive tense Is/am /are + being + P2

The present perfect tense Have/has + been + P2

The simple past tense Were/was + P2

The past progressive tense Were/was + being + P2

The past perfect tense Had + been + P2

The simple future tense Will + be + P2

The future progressive tense Will + be + being + P2

The future perfect tense Will + have + been + P2

The near future tense Is/are/am + going to + be +

P2
Ví dụ:

+ She learns Chinese at school. --> Chinese is learnt at school by her.
+ She bought a book. -->A book was bought by her.

(2)<div class='page_container' data-page=2>

-->A great of property is destroyed by hurricanes each year.

+ The tornado destroyed twenty houses. -->Twenty houses were destroyed by the tornado.
+ They are cleaning the room at the moment. --> The room is being cleaned at the moment
+ They were cleaning the room when I came yesterday.

–> The room was being cleaned when I came yesterday.
+ The company has ordered some new machines.

–> Some new machines have been ordered by the company.

+ Nam will give me a book tomorrow. –> I will be given a book tomorrow by Nam.
Chú ý:

– Trong câu bị động, chúng ta có thể lược bỏ "by ..." (bởi ai đó) khi chủ ngữ đã bao hàm người thực
hiện hành động

Ex: I have done my homework. -> My homework has been done

– Nếu câu chủ động có hai tân ngữ (trực tiếp và gián tiếp), chúng ta có hai cách chuyển đổi:
Ex: He gave me some apples.

–> I was given some apples.
–> Some apples were given to me.

Tuy nhiên, chúng ta ưu tiên cách chuyển đổi đưa tân ngữ chỉ người lên làm chủ ngữ trong câu bị động.
- đối với vật chất gây trạng thái, dùng “with’ thay cho “by”

Ex: Smoke filled the room → The room was filled with smoke.
