conditional sentence

<span class='text_page_counter'>(1)</span>CÂU ĐIỀU KIỆN  Điều kiện có thể xảy ra (probable conditions) Trong mệnh đề If loại 1, mệnh đề chính thường ở thì hiện tại, tương lai, hoặc thể mệnh lệnh. Mệnh đề IF Mệnh đề chính Simple present Future Present Imperative 1. If you go to the drug store, buy me a soft drink. 2. If Mary calls, I’ll invite her to the concert. 3. If Mary should call, I’ll invite her to the concert. Trong loại 1, mệnh đề If ở thì hiện tại. Tuy nhiên, chú ý là trong ví d ụ th ứ 3 c ũng có th ể s ử d ụng động từ should. Nghĩa gần như không khác nhau giữa ví d ụ th ứ 2 và th ứ 3 ngo ại tr ừ cách dùng should được xem là trịnh trọng hơn. Và should cũng có thể diễn tả s ự kém chắc ch ắn h ơn v ề kh ả n ăng Mary gọi điện.  Điều kiện không có thật ở hiện tại (present-unreal conditions) Mệnh đề IF Mệnh đề chính Simple past S + would/should/could/might + bare_inf (bewere) 1. If I had the money, I would buy a motorcycle. 2. If John were here, he could fix the plumbing.  Điều kiện không có thật ở quá khứ (past-unreal conditions) Mệnh đề IF Mệnh đề chính Past perfect (S + had + PP) S + would/should/could/might + have + PP 1. If I had known you were sick, I would have made you some soup. Ở đây, câu có nghĩa là tôi đã không biết bạn bị bệnh (và có thể bạn đã hết bệnh) 2. If you had been here yesterday, you could have seen Pam. Trong ví dụ này, rõ ràng là bạn đã không có mặt ở đây ngày hôm qua.  Chú ý cả 2 ví dụ đều chỉ các tình huống ở quá khứ, chứ không phải ở hiện tại. Từ If giúp bạn nhận biết được mệnh đề if. Nhưng không phải lúc nào nó cũng hiện diện. Chú ý các trường hợp đặc biệt sau. Loại 1: Should 1. If you should get me a letter from Greece, give me a call. 2. Should you get me a letter from Greece, give me a call. Chú ý rằng trong ví dụ thứ 2, if được bỏ đi, should và chủ ngữ you hoán đổi vị trí. Loại 2: were 1. If you were taller, you could reach the light. 2. Were you taller, you could reach the light. Một lần nữa if được bỏ đi. Lần này were hoán chuyển vị trí với chủ ngữ you..

<span class='text_page_counter'>(2)</span> Loại 3: had 1. If I had agreed, Jim would have married me. 2. Had I agreed, Jim would have married me. Chú ý rằng trong ví dụ thứ 2, if được bỏ đi, và had được hoán chuyển vị trí với chủ ngữ I. Trong cả 3 loại này, nghĩa không thay đổi đáng kể. Tuy nhiên, hoán vị được xem là tương đối trịnh tr ọng. Unless, có nghĩa tương tự như if not, cũng có thể được dùng trong mệnh đề điều kiện. Hai câu sau có nghĩa tương tự: 1. If it doesn’t rain, we’ll go to the lake. 2. Unless it rains, we’ll go to the lake. Exercise 1: Supply the correct tense of the verb in parentheses. 1. If today (be) Sunday, we would go to the beach. 2. If we (invite) her, she might go dancing with us. 3. If I finish the work in time, I (go) to the football game. 4. If he (have) your address, he would have written to you. 5. Unless they (pass) their examinations, they would join the army. 6. If he had told them the truth, they (not punish) him. 7. These plants will die if you (not water) them regularly. 8. What you (do) if she refuses your invitation? 9. He never does his homework. If he (do) his homework, he (not worry) about his examinations. 10. It’s too bad we lost the game. If you (play) for us, we (win).  Sentence Transformation : 1.. IF. UNLESS. + Qui taéc: - Không thay đổi thì. - Chỉ thay đổi ở mệnh đề IF / UNLESS: phủ định khaúng ñònh .
