CÁC DẠNG BÀI TẬP LIÊN QUAN ĐẾN CÂU ĐIỀU KIỆN
I SENTENCE TRANSFORMATION: (chuyển đổi câu cùng nghĩa)
1 BECAUSE / SO IF (sử dụng đối với ĐK loại 2, và 3): Khi câu gốc có sử dụng BECAUSE /
SO và viết sang dạng câu ĐK thì ta làm như sau:
a) Câu có sử dụng BECAUSE / SO là sự thật ở Hiện Tại hoặc Quá Khứ, khi viết sang IF thì
ta phải nói ngược lại với sự thật đó (sử dụng NOT, hay bỏ NOT, hoặc dùng từ trái nghĩa) 1/ I am in a hurry , so I won't stay to dinner Sự thật ở _
If………
2/ I had an accident because I didn’t drive carefully Sự thật ở _
If………
b) Nếu BECAUSE / SO là sự thật ở HT ĐK loại 2 Nếu BECAUSE / SO là sự thật ở QK ĐK loại 3
c) Mệnh đề BECAUSE đổi thành mệnh đề IF, mđ còn lại thành mđ chính
Mệnh đề SO đổi thành mệnh đề chính, mđ còn lại thành mđ IF a) John ate too much birthday cake, so he was sick
………
b) We came home from our holiday early because we ran out of money
………
c) The house didn't burn down because the fire brigade came immediately
………

wet

Do đó ĐK loại 3 luôn không thể xảy ra ở QK vì nó TRÁI NGƯỢC với sự thật ở QK
Trang 4UNIT 5 – HIGHER EDUCATION 2010 - 2011
2 IF + S + V- not = Unless + S + V (sử dụng đối với ĐK loại 1, 2, và 3)
EX:
a) If you are not careful, you will make mistake (Nếu bạn không cẩn thận, bạn sẽ phạm sai lầm)
Unless you careful, you will make mistake.
b) These plants will die if you don’t water them regularly.
These plants will die unless you _ them regularly
NOTE: IF loại gì thì UNLESS loại đĩ.
- Nếu mệnh đề IF dùng trợ động từ DO / DOES / DID + NOT , thì ta bỏ hết chỉ lấy động từ chính và chia thì cho nĩ.(don’t water water)
- Nếu mệnh đề IF dùng trợ động từ BE/ HAVE/HAS /HAD + NOT, thì ta chỉ cần bỏ NOT
3 Cĩ thể diển tả câu đk mà khơng cần dùng If hay Unless bằng cách đảo ngữ, lưu ý chỉ áp dụng với động từ Be (loại 2) hoặc động từ Had (loại 3).
Ex:
a) If I were you, I wouldn’t do that Were I you, I wouldn’t do that
b) If he hadn’t resigned,we would have been forced to sack him
Had he not resigned, we would have been forced to sack him
4 Nột số cụm từ cĩ cùng nghĩa với If :
- Provided( that )/ on condition( that )/ as long as/ so long as: miễn là, điều kiện là
- Suppose/ supposing: Nếu như
- In case: để phịng khi
- But for: nếu khơng vì + Noun phrase (A / AN / THE + ADJ + NOUN)
- Without: khơng cĩ
EXERCISE: Chia động từ trong ngoặc và sử dụng các cụm từ thay cho IF
a) I (lend) you my book if you let me have it back by Monday (on condition (that))
I will lend you my book on condition that you let me have it back by Monday
b) If you look after it, I (let) you keep my bicycle till the weekend (providing (that))
