1. Tổng quan câu điều kiện loại 1

1.1 Cấu trúc 

Câu điều kiện loại 1 được sử dụng khi muốn nói đến một sự việc nào đó có thể xảy ra ở hiện tại hoặc trong tương lai dưới một điều kiện nhất định. Cấu trúc câu điều kiện loại 1 gồm có hai mệnh đề: một mệnh đề “if” và một mệnh đề chính. 

Cấu trúc: If + S + V (present simple), S + will + V

Ví dụ:

If you talk like that, I will tell Mom what you did. 

If Hoa comes here, her friends will help her with her homework.

Lưu ý:

- Có thể đảo ngược thứ tự để mệnh đề “if” đứng sau mệnh đề chính, không cần dấu phẩy. (Ví dụ: I will tell mom what you did if you talk like that.)

1.2 Cách dùng

• Mệnh đề chính dùng “may” hoặc “might” để nói đến sự kiện trong tương lai có thể xảy ra, nhưng không chắc chắn. 

Ví dụ: If it’s a rainy day tomorrow, we might stay at home to watch TV. 

• Có thể thay ‘will’ bằng ‘be going to’ trong mệnh đề chính nhằm nhấn mạnh một kết quả chắc chắn.

Ví dụ: I’m going to pay you 10$ if you help me fix the AC.

• Cấu trúc Unless (Nếu không… thì…) 

Unless + S + V-s/es, S + will (not) + V-inf + O.

= If + S + doesn't/don’t + V, S + will (not) + V-inf + O.

Ví dụ: 

Unless you talk like that, I won’t tell Mom what you did. = If you don’t talk like that, I won’t tell Mom what you did.

• Có thể dùng thì hiện tại đơn ở cả hai mệnh đề khi muốn đề cập một hành động tiếp diễn sau một hành động khác:

Ví dụ: If she earns any money, she save it for a long term. (Nếu cô ấy kiếm được đồng nào thì liền dành tiết kiệm.)

• Có thể thay “will” bằng “can” thể hiện sự đồng ý, cho phép. 

Ví dụ:  If it’s sunny tomorrow, we can go on a picnic in the park. 

• Mang ý khuyên nhủ, gợi ý với “should” ở mệnh đề chính.

Ví dụ: If you want to pass the final exam, you should focus on studying. 

• Với câu mệnh lệnh, có thể giản lược chủ ngữ ở mệnh đề chính.

Ví dụ: If you are thirsty, please drink that juice.

1.3 Biến thể câu điều kiện loại 1

a. Biến thể mệnh đề if

• Sự việc đang xảy ra trong tương lai: 

If + thì hiện tại tiếp diễn, S + thì tương lai đơn

Ví dụ: If you are cooking dinner, I will help you answer the phone. 

• Sự việc không chắc về thời gian: 

If + thì hiện tại hoàn thành, S + thì tương lai đơn

Ví dụ: If you has written the letter, I will send it. 

b. Biến thể mệnh đề chính

• Nhấn mạnh tính tiếp diễn hay hoàn thành sự việc: 

If + thì hiện tại đơn, S + thì tương lai tiếp diễn/ tương lai hoàn thành

Ví dụ: If we start our meeting now, we will have finished by 10AM. (Nếu bắt đầu buổi họp bây giờ thì chúng ta sẽ hoàn thành xong trước 10 giờ.)

• Câu mệnh lệnh: If + thì hiện tại đơn, (don’t) V-inf

Ví dụ: If you don’t clean the house, don’t go out! (Nếu không dọn nhà thì con không được ra ngoài.)

• Câu khuyên nhủ, đề nghị:

If + thì hiện tại đơn, S + should/must/have to/… + V-inf

Ví dụ: If you don’t feel good, you should stay at home. (Nếu bạn không cảm thấy ổn, bạn nên nghỉ ở nhà.)

1.4 Đảo ngữ câu điều kiện loại 1

Cấu trúc: SHOULD + S + (not) + V-inf, (S + will/can/might/…) + V-inf

Ví dụ: If Lan comes, I will tell her to help you with homework. (Nếu Lan đến, hãy nói cô ấy giúp cậu làm bài tập.)

=> Should Lan come, I will tell her to help you with homework.
