PHẦN MỞ ĐẦU
Ngoại ngữ nói chung và Tiếng Anh nói riêng đã, đang và sẽ trở thành một
môn văn hóa cơ bản trong chương trình giáo dục phổ thông. Đồng thời việc
giảng dạy ngoại ngữ - Tiếng Anh cũng đang được các nhà trường, các nhà
giáo dục, nhiều dự án giáo dục và đông đảo giáo viên quan tâm và đưa ra
nhiều phương pháp dạy học thích hợp. Trong chương trình Tiếng Anh
THPT, Câu Điều Kiện – Conditional Sentences, là một trong các phần ngữ
pháp lớn có trong các kì thi tốt nghiệp THPT, ĐHCĐ và thi học sinh giỏi.
Tuy nhiên, đại đa số học sinh mới nắm được cấu tạo và cách sử dụng của
câu điều kiện loại 1 (type 1), loại 2 (type 2) và loại 3 (type 3). Các em
thường vẫn lúng túng khi gặp các loại câu điều kiện có hình thức hỗn hợp.
Do vậy nhiều học sinh đã gặp khó khăn trong việc phân biệt và làm các bài
tập liên quan câu điều kiện.
Vì vậy tôi mạnh dạn đưa ra một số hình thức nhận biết câu điều kiện
theo quan niệm cũ và quan niệm mới cùng một số dạng bài tập thường gặp
nhằm giúp các em củng cố ngữ pháp và luyện tập một cách hiệu quả và đạt
kết quả cao trong các kì thi.

(If – clause) và mệnh đề chính ( Main clause).

If- clause: If it rains
Main clause: I will stay at home.
II. TYPES OF CONDITIONAL SENTENCES (Các loại câu điều kiện)
A. Câu điều kiện theo quan điểm cũ
Có ba loại câu điều kiện:
1. Câu điều kiện loại 1 (Conditional sentences: type 1)
- Diễn tả những hành động, sự việc có khả năng thực hiện được, hoặc có khả
năng xảy ra ở hiện tại hoặc tương lai.
FUTURE ACTIONS
Eg. If you don’t work hard, you will not pass the exam.
THÓI QUEN (HABITUAL)

trái ngược với thực trạng ở hiện tại.

9. Cách sử dụng will, would, could, should trong một số trường hợp khác
Thông thường các trợ động từ này không được sử dụng với if trong mệnh đề
điều kiện của câu điều kiện, tuy nhiên vẫn có một số ngoại lệ như sau:
If you (will/would): Nếu ..... vui lòng. Thường được dùng trong các yêu cầu
lịch sự. Would lịch sự hơn will.
If you will/would wait for a moment, I will go and see if Mr Conner is
here.
•
If + Subject + Will/Would: Nếu ..... chịu. Để diễn đạt ý tự nguyện.
If he will listen to me, I can help him.
Will còn được dùng theo mẫu câu này để diễn đạt sự ngoan cố:
Vũ Thị Kim Oanh

THPT Nguyễn Duy Thì
Nếu ..... nhất định, Nếu ..... cứ.
If you will turn on the music loudly so late tonight, no wonder
why your neighbours complain.
•
If you could: Xin vui lòng. Diễn đạt lịch sự 1 yêu cầu mà người nói
cho rằng người kia sẽ đồng ý như là một lẽ đương nhiên.
If you could open your book, please.
• If + Subject + should + ..... + command: Ví phỏng như. Diễn đạt
một tình huống dù có thể xảy ra được song rất khó.
If you should find any difficulty in using that TV, please call me.
10. Cách sử dụng if trong một số trường hợp khác
•
If... then: Nếu... thì
If she can’t come to us, then we will have to go and see her.
•
If dùng trong dạng câu suy diễn logic (không phải câu điều kiện):
Động từ ở các mệnh đề diễn biến bình thường theo thời gian của chính
nó.
If you want to learn a musical instrument, you have to practice.
If you did not do much maths at school, you will find economics
difficult to understand.
If that was Marry, why didn’t she stop and say hello.
•
If... should = If... happen to... = If... should happen to... diễn đạt sự
không chắc chắn.
If you should happen to pass a supermarket, perhaps you could get
some eggs.
Vũ Thị Kim Oanh

THPT Nguyễn Duy Thì
If.. was/were to... Diễn đạt điều kiện không có thật hoặc tưởng tượng.
Nó gần giống câu điều kiện không có thật ở hiện tại.
If our boss was/were to come in now (= if the boss came in now),
we would be in real trouble.
What would we do if I was/were to lose my job.
Hoặc có thể diễn đạt một ý lịch sự khi đưa ra đề nghị
If you were to move your chair a bit, we could all sit down.
Note: Cấu trúc này tuyệt đối không được dùng với các động từ tĩnh tại
hoặc chỉ trạng thái tư duy
Correct: If I knew her name, I would tell you.
Incorrect: If I was/were to know...
•
If it + to be + not + for: Nếu không vì, nếu không nhờ vào.
Thời hiện tại:
If it wasn’t/weren’t for the children, that couple wouldn’t have
any thing to talk about.
Thời quá khứ:
If it hadn’t been for your help, I don’t know what to do.
Not đôi khi được thêm vào những động từ sau if để bày tỏ sự nghi
ngờ, không chắc chắn. (Có nên ... Hay không ...)
I wonder if we shouldn’t ask the doctor to look at Mary.
•
It would... if + subject + would... (sẽ là... nếu – không được dùng
trong văn viết)
It would be better if they would tell every body in advance.
How would we feel if this would happen to our family.

diễn đạt điều kiện không thể xảy ra ở quá khứ

•
If + preposition + noun/verb... (subject + be bị lược bỏ)
If in doubt, ask for help. (= If you are in doubt, ...)
If about to go on a long journey, try to have a good nights sleep.
(= If you are about to go on... )

•
•

(There is little evidence, if there is any at all, for flying saucers)
I’m not angry. If anything, I feel a little surprised.
Cách nói này còn diễn đạt ý kiến ướm thử: Nếu có...

If + Adjective = although (cho dù là)
Nghĩa không mạnh bằng although

K ẾT LU ẬN
Trong quá trình giảng dạy Tiếng Anh tại trường , tôi đã giới thiệu cho các
em những kiến thức cơ bản về câu điều kiện trong Tiếng Anh. Đối với từng
đối tượng học sinh khác nhau thì yêu cầu về kiến thức cũng khác nhau. Đối
với những học sinh yếu tôi chỉ giới thiệu những kiến thức cơ bản để các em
phân biệt được ba loại câu điều kiện trong bài tập tự luận và trắc nghiệm.
Đối với học sinh có lực học khá giỏi tôi cung cấp kiến thức cao hơn. Vì vậy
trong quá trình giảng dạy tôi nhận thấy phần lớn học sinh đã nắm được các
kiến thức cơ bản và áp dụng làm được các bài tập trắc nghiệm phục vụ cho
thi tốt nghiệp THPT và Cao Đẳng- Đại H ọc
Khi thực hiện chuyên đề này giáo viên nên chú ý đến chủ điểm, cấu
trúc ngữ pháp và từng đối tượng học sinh để đề ra yêu cầu phù hợp. Hướng
dẫn cho học sinh hiểu rõ yêu cầu, song nó phải mang tính logic, mặt khác
phải tôn trọng tính độc lập và sáng tạo của học sinh.
Khi nghiên cứu chuyên đề nầy tôi mong muốn áp dụng những nội
dung yêu cầu của lí thuyết và dạng bài tập rèn luyện ngữ pháp vào việc
giảng dạy môn Tiếng Anh trong trường THPT. Đồng thời tôi cũng mong
muốn được sự tham gia đóng góp của bạn bè đồng nghiệp để nội dung vấn
đề thêm phong phú và hoàn hảo hơn.
Tôi xin chân thành cảm ơn!
