新東方白易禮：英語四級(jí)考試語法筆記(六)

　　(fact: You often go to bed late, so you are always sleepy in the morning.)

　　If this were the case, it would be very awkward.

　　(fact: This is not the case, so it is not awkward.)

　　Now let’s do some translation:

　　要是沒有虛擬語氣，英語就會(huì)容易多了。

　　If there were no subjunctive mood, English would be much easier.

　　如果我是你，我就在房屋周圍種些樹。

　　If I were you, I would (should) plant some trees around the house.

　　如果我把頭發(fā)染成藍(lán)色，人人都會(huì)笑話我。

　　If I dyed my hair blue, everybody would laugh at me. Or: I would (should) be laughed at by everybody.

　　要不是她這么忙，她就會(huì)出席今天下午的會(huì)議了。

　　If she were not so busy, she would attend the meeting this afternoon.

　　2、對(duì)過去的虛擬，表示與過去的事實(shí)相反的假設(shè)時(shí)，條件狀語從句的謂語動(dòng)詞用過去完成時(shí),主句的謂語動(dòng)詞用would (should, could, might)+過去分詞。見下表：

　　例句：

　　If you had taken my advice, you wouldn’t have failed in the examination.

　　(fact: You did not take my advice, so you have failed in the examination.)

　　I would have checked my paper again if I had had more time at yesterday’s examination.

　　You didn’t let me drive. If we had driven in turn, you wouldn’t have got so tired.
