虛擬語氣10大必背句型
一、虛擬條件句:
條件狀語從句是非真實情況,在這種情況下要用虛擬語氣。
1.條件從句與現在事實不一致,其句型為:
句型1:If +主語+過去時,主語+ should (could, would, 或might) +動詞原形
If I were you, Iwould study hard.
If it rained, Iwould not be here now.
2.條件從句與過去事實不一致,其句型為:
句型2: If +主語+had+過去分詞,主語+ should(could, would, 或might)+ have +過去分詞
If the doctor hadcome last night, the boy would have been saved.
If I had not studiedhard, I would have failed in the exam last term.
3.條件從句與將來事實不一致,其句型為:
句型3:If +主語+過去時/ should +動詞原形/ were to+動詞原形,主語+ should (could, would, 或might) +動詞原形
If it should raintomorrow, we would stay at home.
If I were to go tothe moon one day, I could see it with my own eyes.
If you missed thefilm tonight, you would feel sorry.
注意問題:
1.If條件句中絕對不可以出現would。
2.根據句中的時間狀語,有時可能出現“混合虛擬”的情況,即主句可能是現在的情況,條件句也許是發生在過去的情況,但都要遵守上述句型。如:
If you had studied hard before, you would be a college student now and you would graduate from a college in four years’ time.
3.條件句中如果出現were, had, should可省去if,將主語與這些詞倒裝。例如:
Had the doctor come last night, the boy would have been saved.
Were I to go to the moon one day, I would see it with my own eyes.
Should it rain tomorrow, we would stay at home.
二、名詞性虛擬語氣:
在表示命令、建議、要求、驚歎時的名詞性從句中需用虛擬語氣,基本句型:
句型4:主語+(should)+動詞原形
Mother insisted thatJohn (should) go to bed at 9 o’clock.(賓語從句)
It was required thatthe crops (should) be harvested at once.(主語從句)
It is surprising that she shouldn’t pass the math exam. (主語從句)
The suggestion tha the (should) be invited was rejected.(同位語從句)
Their demand is that their wages (should) be increased.(表語從句)
注意:在這種句子中絕不可以出現would,must, could等。
三、虛擬語氣在一些特殊詞中的使用或含蓄條件句:
句型5:wish後的賓語從句
與現在願望不一致:主語+過去時
與過去願望不一致:主語+ had +過去分詞/ could +have+過去分詞
與未來願望不一致:主語+ would / could +動詞原形。如:
I wish I were you.
I wish I had visited the White House when I was in the States.
I wish I could meet you tomorrow at the party.
句型6:It’s time句型(當It’s time後用that從句時應該為“主語+ should +動詞原形”或“主語+過去時”)
It’s time that you went / should go to school.
句型7:If only引起的感嘆句相當於“How I wish +賓語從句”
If only he could come! 他要能來就好了。
If only I had known the answer! 我要早知道答案就好了。
句型8:would rather, as if(though)引導的句子也需使用虛擬,表示過去的情況用過去完成時,表示現在與將來的情況用過去時。
I’d rather you posted the letter right away.
I’d rather you had returned the book yesterday.
She loves thechildren as if they were hers.
Alan talked about Rome as if he had been there.
句型9:without, but, but for, but that, otherwise引起的短語或句子常暗含著虛擬條件。
Without you, I would never know him.
But for your cooperation, we wouldn’t have done the work so well.
But that she was afraid, she would have said no.
I would be most glad to help you, but I’ am busy now.
I should have come to the party yesterday, but I was busy.
I am busy nowotherwise I would do you the favor!
句型10:If it were not for ... / If it hadn’t beenfor ... (要不是因為……),其後面的主句也需使用虛擬語氣。
