If only là gì? | Định nghĩa - Cấu trúc - Phân biệt If only và Only if - Bài tập vận dụng

If only là gì?

Trong tiếng Anh, cấu trúc If only khi đi cùng một mệnh đề có nghĩa là “Giá như ai làm gì” hay “Ước ai làm gì”. Những mong ước này có thể được sử dụng cho thì hiện tại, tương lai và quá khứ. 

Ví dụ:

• If only Jenny brought an umbrella. It is going to rain. (Giá như là Jenny mang ô. Trời chuẩn bị mưa rồi.) 
• If only my father would buy this car. (Giá như bố tôi sẽ mua chiếc xe ô tô đó.) 
• If only Anna had come to my birthday party last week. (Giá như Anna đã tham gia tiệc sinh nhật của tôi tuần qua.) 

Cấu trúc If only

1. Cấu trúc If only ở tương lai

Để diễn tả những mong ước sẽ được xảy ra trong tương lai, bạn có công thức If only sử dụng như sau:

If only + S + would V: Giá như ai sẽ làm gì

Ví dụ:

• If only our team would get that price. (Giá như nhóm chúng tôi đạt được phần quà đó). 
• If only Jenny would attend my wedding. She is studying abroad. (Giá như Jenny sẽ tham dự được đám cưới của tôi. Cậu ấy đang đi du học).

2. Cấu trúc If only ở hiện tại

Nếu như diễn tả những mong muốn trong hiện tại (mong muốn trái với hiện tại) thì ta dùng cấu trúc If only như sau:

If only + S + V-ed: Giá như ai đó làm gì

Ví dụ:

• If only Jenny knew the truth. (Jenny doesn’t know the truth but Jenny wishes she knew.) (Giá như Jenny biết được sự thật.) 
• If only Peter loved her. (Giá như Peter yêu cô ấy.) 
• If only there was something I could do to help you. (Giá như có điều gì đó mà tôi có thể giúp bạn.) 

Lưu ý: Trong trường hợp lịch sự, chúng ta sử dụng “were” thay thế cho “was”. Ví dụ:

• If only the leader weren’t so tired, our team could continue the meeting. (Giá như người đứng đầu không quá mệt thì nhóm tôi có thể tiếp tục cuộc họp.) 

3. Cấu trúc If only ở quá khứ

Để diễn tả những mong muốn trong quá khứ (mong muốn trái với việc đã xảy ra trong quá khứ), bạn dùng cấu trúc If only như sau:

If only + S + had PII: Giá như ai đó (đã) làm gì

Ví dụ:

• If only Anna had listened to what I had told her. (Anna didn’t listen to what I had told her). (Giá như Anna đã lắng nghe những gì tôi nói với cô ấy.) 
• If only my family had not gone to this place. (Giá như gia đình tôi đã không đi tới nơi này.) 
• If only John had studied harder last year. (Giá như John đã chăm học hơn vào năm ngoái.)

4. Cấu trúc If only trong câu ước

Như đã đề cập ở trên, cấu trúc If only mang ý nghĩa giống với cấu trúc Wish (câu ước). Hơn nữa, hai cấu trúc này cũng có công thức giống nhau. Vậy nên bạn có thể thay thế cấu trúc If only bằng câu ước sử dụng “wish”.

Ví dụ:

• If only Anna understood this exercise.= I wish Anna understood this exercise. (Ước gì Anna hiểu được bài tập này.) 
• If only Peter had joined the competition. = I wish Peter had joined the competition. (Ước gì Peter đã tham gia cuộc thi.) 

Phân biệt If only và Only if 

Hai cấu trúc If only và Only if tuy chỉ đổi vị trí từ nhưng mang ý nghĩa khác hẳn nhau, vì thế rất nhiều bạn bị nhầm lẫn.

Cấu trúc If only mang nghĩa là “Giá như”, còn Only if mang nghĩa là “Chỉ khi”.

Cấu trúc Only if được dùng trong câu điều kiện nhằm mục đích nhấn mạnh.

Only if S + V, S + V: Chỉ khi ai làm gì, thì ai làm gì

Ví dụ:

• We are allowed to come in only if the boss gives permission – Chúng tôi được phép vào chỉ khi người chủ cho phép thôi. 
• Only if Jenny studies hard, she will get a high score – Chỉ khi Jenny học hành chăm chỉ thì cô ấy mới đạt điểm cao được. 
• Anna will come only if you call her – Anna sẽ tới chỉ khi bạn gọi cô ấy.
