Will đứng sau if : Thơng thường khơng dùng tương lai đơn với will sau if Tuy nhiên, dùng đến, người ta dùng hình thức muốn nhấn mạnh đến ý " mà sau này" Hãy so sánh: If it suits you, I will change the date of our meeting anh thấy thuận tiện đổi ngày họp lại If it will suit you, I will change the date of our meeting anh thấy thuận tiện ( mà sau ) tơi đổi ngày họp lại Will would đứng sau if : - Muốn nhấn mạnh đến lịng khơng lịng: + Khi u cầu người khác làm việc gì/ đáp ứng đề nghị giúp đỡ Ví dụ : Shall I hold the door open for you ? anh có muốn tơi để cửa mở cho anh không? Yes, if you will/would vâng, xin anh vui lịng Ví dụ : If you will/would/could wait a moment, I will fetch the money anh vui lịng chờ chút, tơi lấy tiền + Khi nói người khác: If he will/would/could only try harder, I am sure he'd well: chịu cố gằng nữa, thành cơng + Trong hình thức lịch mạch văn trang trọng: Ví dụ 1: I'd be grateful if you will/would let me know soon.: lấy làm biết ơn ông vui lịng cho tơi biết sớm Ví dụ 2: If you will/would follow me, I will show you the way anh chịu theo tơi tơi đường cho anh + Trong câu nói trực tiếp lịng/ khơng lịng Ví dụ 1: If you will/would agree to pay us compensation, We will/would agree not to take the matter any further : anh chịu bồi thường cho chúng tơi chúng tơi lịng khơng đá động đến vấn đề Ví dụ 2: If you won't stop smoking, you can only expect to have a bad cough : anh khơng chịu ngưng hút thuốc anh anh bị ho CÂU ĐIỀU KIỆN NÂNG CAO: Dùng were to bên mệnh đề có if: Để diễn tả hồn cảnh tưởng tượng tương lai: Ví du: If the government were to cut V.A.T, prices would fall (Tưởng tưởng cho thư giản trang thời buổi “gạo châu củi quế” ) If he were to win the game, he would be rich (Tưởng tượng thơi khơng dễ thắng đâu) Để đề nghị cách lịch sự: Ví dụ: If you were to ask him, he might help you (Nếu bạn mà nhờ đến giúp bạn) If you were to move over, we could all sit on the sofa Lưu ý: Công thức không áp dụng cho động từ tình trạng như: know, like, remember, understand… Ví dụ: If I were to remember… ( sai) If I remembered… ( đúng) Trong công thức were đem ngồi if, có not khơng đem not theo mà phải để lại sau chủ từ Ví dụ: Weren’t the government to cut… (sai) Were the government not to cut… (đúng) Dùng it was/were not for + noun bên mệnh đề if Người ta dùng cấu trúc để diễn tả hoàn cảnh lệ thuộc vào hoàn cảnh hay người khác Ví dụ: If it were not for you, I would die (Nếu khơng có bạn “tiêu” rồi) Đối với chuyện khứ ta dùng: if it hadn’t been for… Các em dùng but for để thay cơng thức mà khơng thay đổi nghĩa: Ví dụ: If it were not for you,… = but for you,… Phân biệt if ….not unless: Thông thường, cấp độ em thay if… not unless Tuy nhiên, cấp độ nâng cao em gặp trường hợp chúng thay Không thể dùng unless thay cho if not trường hợp sau: Trong tình khơng thật (thường câu loại 3) Ví dụ: She would be a good friend if she were not selfish She would be a good friend unless she were selfish (sai) If he had not been absent, he would have known that Unless he had been absent, he would have known that (sai) Khi nói cảm xúc: I will be disappointed, if you don’t pass the exam I will be disappointed, unless you pass the exam (sai) Trong hầu hết câu hỏi: Ví dụ: What you think if I don’t come? What you think unless I come? (sai) Không thể dùng if not thay cho unless trường hợp sau: Khi ta nhắc đến việc qua với nhận xét Cách nhận tình có dấu gạch nối trước unless Ví dụ: I couldn’t have gone to school on time – unless I had got up earlier (Tôi học giờ- Trừ dậy sớm hơn.) Trong tình này, thực tế tơi không học không dậy sớm So sánh với câu dùng if not I couldn’t have gone to school on time, if I had not got up earlier (Tôi học không thức dậy sớm hơn) Trong trường hợp thực tế dậy sớm học Nghĩa hoàn toàn ngược với câu Khi ta nói xong câu, sau thêm vào ý Trường hợp phải có dấu gạch nối Ví dụ: Because my secretaty is in the hospital, the work can’t continue – Unless you take up her position, of course (Vì thư kí tơi nằm viện, công việc tiếp tục – Dĩ nhiên trừ thay vị trí ấy.) Because my secretaty is in the hospital, the work can’t continue if you don’t take up her position, of course (sai) Câu điều kiện loại zero Người ta gọi tên “zero” có lẽ thấy vế chia đơn Cách dùng: Diễn tả chân lí, qui luật: Ví dụ: If water is frozen, it expands Nếu nước bị đơng đặc nở (Đây thật, chân lí lúc nên dùng loại zero) Phân biệt: If the water is frozen, it will expand Nếu nước bị đơng đặc nở (Đây hoàn cảnh cụ thể, khối nước cụ thể xác định nên khơng dùng loại zero) Diễn tả thói quen: Ví dụ: If it rains, I go to school by taxi (Đây thói quen khơng phải hồn cảnh cụ thể nên dùng loại zero) Phân biệt: If it rains this evening, I will go to school by taxi (Đây hồn cảnh cụ thể khơng phải thói quen nên khơng dùng loại zero) Câu điều kiện loại hổn hợp Loại hổn hợp loại câu điều kiện mà vế khác loại Ví dụ: If you had not spent too much yesterday, you would not be broke now (Nếu hôm qua bạn không xài nhiều tiền hơm đâu có túi vầy) => Loại + loại If you liked animals, I would have taken you to the zoo => Loại 2+ loại If she arrived there yesterday, she can come here tomorrow => Loại + loại Như em thấy loại hổn hợp đa dạng Vấn đề đặt biết chia vế loại Để làm loại hổn hợp em cần nắm vững bí sau: Trước tiên em phải hiểu chất câu điều kiện thật chia động từ theo thời gian nó, cịn khơng có thật, khó xảy giả sử thơi lùi Khi nắm nguyên tắc em xem xét vế riêng biệt mà chia chư khơng chia vế xong thấy loại vội vàng chia vế dễ sai Thử lấy ví dụ phân tích xem If you had not spent too much yesterday, you would not be broke now Vế đầu chuyện xảy q khứ khơng có thật (nếu hơm qua khơng xài nhiều tiền => thực tế xài nhiều tiền) Bình thường động từ khứ chia q khứ đơn khơng thật nên ta giảm xuống thành QKHT Vế sau chuyện khơng có thật nên từ will giảm thành would ( dùng will cơng thức câu điều kiện) If you liked animals, I would have taken you to the zoo Vế đầu nói sở thích chung chung nên bình thường chia khơng thật nên giảm xuống khứ Vế sau việc khứ nên giảm xuống thành would have p.p Tóm lại: Các em khơng nên học chi tiết loại hổn hợp mà cần nhớ nguyên tắc chiếu theo mà xem xét vế Lưu ý phải đọc kỹ manh mối cho câu đề để định thời gian biết có xảy hay khơng Thơng thường có sở để em xét: -Thời gian khứ -Thời gian tại/tương lai -Thói quen Bài tập câu điều kiện Để làm tốt câu điều kiện, làm số tập I/Chia động từ ngoặc If I (know)………………………….…… that you were ill, I (go)…………….…………… to see you 2 If she'd had enough money, She (buy) …………………………………………………………………… a car I (buy) …………………………………………………………… a car If you lend me some money I (see) ……………………………….…… him if I (go) …………….……………… to the party last night We could have gone out if the weather (not be)…………………… ………………………………… so bad If the book (not be )………………….…… expensive, I'll buy it You would be very surprised if he (return)………………………………………………… ……… I'll go out if it (not rain)………………………………………………………… ……………………… They wouldn't come to the party if you (not invite) …………………………………………… them 10 What ……………………………… you (do) ……………………… if you (be) …………………… him? 11 If that hat costs much, I (buy) …………………………………….……… a small one 12 If you (drive) ……………………… more carefully, you (have) ……………………… so many accidents 13 If I (make) …………………… that mistake again, my teacher (get) ………… ………… angry with me 14 If I spoke English, my job (be) ……………………………………………….……………… a lot easier 15 If he (go) ………………………… toLondon yesterday, he ( meet) ……………………… his old friend 16 I will lend them some money if they (ask) ……………………………….……………… me 17 If we had known who he was, we (invite) ……………………….…………… him to speak at our meeting 18 My dog (bark) ………………………………… if it (hear) ………………….………… any strange sound 19 If I (have) ………………………………………………… ……… enough money, I would buy a house 20 They (not/let) ……………………………………………………………………… you in if you (come) late 21 If you (not go) …………………………… away, I (send) …………….……………… for a policeman 22 If I (be) ………………………………… in your place, I (accept) ………………………………… Mr Anderson’s invitation 23 If I (win) ………………………………………………… a big prize in a lottery, I’d give up my job 24 If I (be) ……………………….………… you, I (tell) …………………… ………………… the truth 25 I was busy If I (have) …………………………… ……… free time I (go) ………………… ……………… to the cinema with you 26 Why didn’t you attend the meeting?
