Câu điều kiện là gì ?

Câu điều kiện (Conditional sentences) là dạng câu dùng để diễn đạt một sự việc sẽ xảy ra khi có một điều kiện cụ thể xảy ra

Ví dụ: “If it rains, the picnic will be cancelled (Nếu trời mưa, chuyến dã ngoại sẽ bị hủy bỏ)”.

Trong đó, mệnh đề phụ (còn được gọi là mệnh đề if) diễn đạt điều kiện, còn mệnh đề chính diễn đạt kết quả (result).

Các loại câu điều kiện

4 loại câu điều kiện phân chia theo 0, 1, 2, 3 và một số dạng biến thể khác (tổng là 6). Thường mệnh đề if sẽ đứng trước và phân cách hai mệnh đề bằng dấu phẩy. Nhưng nếu đổi chỗ hai mệnh đề thì không cần dấu phẩy.

Ví dụ: I will buy this bag for you if you help me to do my homework (Tôi sẽ mua cái cặp này cho bạn nếu bạn giúp tôi làm bài tập về nhà).

Tổng hợp công thức câu điều kiện:

Loại Công thức Cách sử dụng Ví dụ
0 If + S + V(s,es), S+ V(s,es)/câu mệnh lệnh Điều kiện diễn tả thói quen, sự thật hiển nhiên If you freeze water, it becomes solid. (Nếu bạn đóng băng nước, nước sẽ trở nên rắn lại.)
1 If + S + V(s,es), S + Will/Can/shall…… + V

 

Điều kiện có thể xảy ra ở hiện tại ở tương lai If the weather is nice, I will go swimming tomorrow. (Nếu trời đẹp, ngày mai tôi sẽ đi bơi)
2 If + S + V2/ Ved, S +would/ Could/ Should…+ V

 

Điều kiện không có thật ở hiện tại If I were you, I would follow her advice. (Nếu tôi là bạn, tôi sẽ làm theo lời khuyên của cô ấy)
3 If + S + Had + V(pp)/Ved, S + would/ could…+ have + V(pp)/Ved

 

Điều kiện không có thật trong quá khứ If I had studied the lessons, I could have answered the questions. (Nếu tôi học bài thì tôi đã trả lời được câu hỏi)

Câu điều kiện loại 0

Câu điều kiện loại 0 là câu dùng để diễn tả một sự thật, chân lý, hoặc thói quen sẽ xảy ra khi điều kiện nói tới xảy ra trước.

If + S + V (s,es), S + V(s,es)

If this thing happens that thing happens.

Ex: If you freeze water, it becomes a solid (Nếu bạn đóng băng nước, nó sẽ trở thành chất rắn).

*Lưu ý: Bạn có thể thay thế “if” bằng “when” vì đều có ý nghĩa chung như nhau.

Câu điều kiện loại 1

Câu điều kiện loại 1 là câu dùng để dự đoán một hành động, sự việc có thể xảy ra trong tương lai khi có một điều kiện nhất định xảy ra trước.

If + S + V (s,es), S + Will/Can/shall… + V

If + hiện tại đơn, tương lai đơn

E.g: If she works hard, she will pass (Nếu cô ấy làm việc chăm chỉ, cô ấy sẽ đỗ).

Câu điều kiện loại 2

Câu điều kiện loại 2 là câu dùng để diễn tả một hành động, sự việc có thể sẽ không xảy ra trong tương lai dựa vào một điều kiện không có thật ở hiện tại.

If + S + V2/ Ved, S + Would/ Could/ Should… + V

If this thing happened that thing would happen.

To be: were/weren’t

E.g: If I were taller, I would buy this dress (Nếu tôi cao hơn, tôi sẽ mua cái váy đó).

Câu điều kiện loại 3

Câu điều kiện loại 3 là câu dùng để diễn tả một hành động, sự việc đã không xảy ra trong quá khứ bởi điều kiện nói tới đã không xảy ra.

If + S + Had + V(pp)/Ved, S + would/ could… + have + V(pp)/Ved

If this thing had happened that thing would have happened

E.g: If you had studied harder you would have passed the exam (Nếu bạn chăm chỉ hơn, bạn sẽ đỗ kỳ thi).

Biến thể câu điều kiện dạng hỗn hợp

Câu điều kiện hỗn hợp dùng để giả thiết về một hành động, sự việc sẽ xảy ra ở hiện tại nếu điều kiện nói tới trong quá khứ có thật hoặc giả thiết về một hành động, sự việc sẽ xảy ra trong quá khứ nếu điều kiện nói tới có thật.

Loại 1: If + S + had + Vpp/V-ed, S  + would + V-inf

If this thing had happened that thing would happen.

Loại 2: If + S + V-ed, S  + would/could/might + have + Vpp/V-ed

E.g: If I had worked harder, then I would be rich now. (Nếu tôi làm việc chăm chỉ hơn, thì bây giờ tôi đã giàu có).

Biến thể câu kiều kiện dạng đảo ngữ

Trong tiếng Anh, người ta thường dùng dạng đảo, đặc biệt câu loại 2 và 3. Các từ should, were, had đảo lên trước chủ ngữ trong đó should là dùng trong điều kiện loại 1, were dùng trong loại 2 và had dùng trong loại 3.

Công thức đảo câu điều kiện loại 1: Should + S + Vo, S + Will + Vo

Ví dụ: Should I go school tomorrow, I will give my classmate this book. = If I go to school tomorrow, I will give my classmate this book

=> Dịch: Tôi có nên đi học vào ngày mai, tôi sẽ tặng bạn cùng lớp cuốn sách này. = Nếu tôi đi học ngày mai, tôi sẽ tặng bạn cùng lớp cuốn sách này.

Công thức đảo câu điều kiện loại 2: Were + S + to + Vo, S + Would + Vo

Ví dụ: Were I you, I would buy this house. => If I were you, I would buy this house.

=> Dịch: Tôi là bạn, tôi sẽ mua ngôi nhà này. => Nếu tôi là bạn, tôi sẽ mua ngôi nhà này.

Công thức đảo câu điều kiện loại 3: Had + S + V3/Ved, S + Would have + V3/Ved

Ví dụ: Had he driven carefully, the accident wouldn’t have happened. => If he had driven carefully, the accident wouldn’t have happened.

=> Dịch: Anh ấy lái xe chậm lại, tai nạn đã không xảy ra. => Nếu anh ta lái xe chậm lại, tai nạn đó đã không xảy ra.

Các trường hợp khác của câu điều kiện

Unless

Unless được sử dụng thay If… not trong tất cả các loại câu điều kiện.

Câu điều kiện loại 1: Unless + hiện tại đơn

You will be sick if you don’t stop eating.

=> You’ll be sick unless you stop eating. (Bạn sẽ bị bệnh trừ khi bạn ngừng ăn)

Câu điều kiện loại 2: Unless + quá khứ đơn

If he wasn’t very ill, he would be at work.

=> Unless he was very ill, he would be at work. (Anh ấy sẽ đi làm trừ khi anh ấy bị bệnh)

Câu điều kiện loại 3: Unless + quá khứ hoàn thành

Our director would not have signed the contract if she hadn’t had a lawyer present.

=> Our director would not have signed the contract unless she had had a lawyer present. (Đạo diễn của chúng tôi đã không ký hợp đồng trừ khi cô ấy không có luật sư đại diện)

Một số cụm từ đồng nghĩa với if

suppose/supposing

Trong một số trường hợp điều kiện, bạn có thể thay if bằng

Supposing (giả sử như): Đặt ra giả thiết.

Ví dụ: Supposing I don’t arrive till after midnight, will the guest-house still be open? (Nếu tôi không có mặt sau nửa đêm, thì nhà nghỉ có còn mở cửa không?)

Mệnh đề Wish/If only

Bên cạnh câu điều kiện thì Wish, câu ao ước cũng gần giống nhau nên bạn cần học thêm nhé.

Wish là ước, sử dụng tương tự if only – nếu chỉ. Ý nghĩa thể hiện sự tiếc nuối và những điều muốn thay đổi trong quá khứ, hiện tại. Đồng thời là ước mơ ở tương lai.

Cách sử dụng wish trong tương lai

Dùng để diễn tả mong ước về một điều gì đó trong tương lai. Thì sử dụng là thì hiện tại đơn.

Cấu trúc: S + wish (es) + S + would/could + V1

Ví dụ:

He wishes he would be a designer in the future.

I wish it would rain. The garden really needs some water.

Có thể không phải là ước mơ mà là ước muốn, mong muốn thay đổi, có thể đó là điều khiến bạn khó chịu. Sử dụng Wish đi kèm với would

*Lưu ý: wish + would là nói về điều gì đó ở hiện tại không thể thay đổi nên không nói đến quá khứ.

Ví dụ: bạn có thể nói I wish I didn’t eat so much chocolate nhưng không thể nói I wish I wouldn’t eat so much chocolate

Sử dụng wish ở hiện tại

Câu Wish ở hiện tại nói về những mong ước về sự việc không có thật ở hiện tại và có thể là giả định ngược lại so với thực tế.

Cấu trúc: S + wish (es) + S + V2/ed + ...

*Lưu ý: “to be: were/weren’t”

Ví dụ:

I wish I knew what to do.

If only I didn’t have so much homework I could go to the concert tonight. She has a lot of homework and she can’t go to the concert.

Wish sử dụng trong quá khứ

Thể hiện ước muốn về sự việc không có thật ở quá khứ, giả định điều ngược lại so với thực tế đã xảy ra.

Cấu trúc: S + Wish (es) + S+ V3/ed

Ví dụ:

I wish I’d studied harder when I was at school. He didn’t study harder when he was at school.

She wishes she could have been there (She couldn’t be there).
