虛擬語氣用來表達不可能或難以實現的願望,與事實相反的假設,通常分為基本的三種形式

1. 與現在事實相反的虛擬:

If did / were

would

should

could do (動詞原形)

might

If I were you, I would go abroad at once. (I am not you.)

If he knew it now, he could help me. (He doesn't know it now.)

2. 與過去事實相反的虛擬:

If had done would (might) have done ...

If I had known your telephone number yesterday, I would have phoned you.

(I didn't know your telephone number.)

If you had come here a little earlier just now, you might have met her.

(You didn't come here earlier.)

3. 與將來事實相反的虛擬:

(1) If should v.,   would v.

可能性很小)(譯作“一”)

If it should rain tomorrow, you could stay at home.

If I should fail, what should Ido?

(2) If did / were to v , would v.

完全不可能

If the sun were to rise in the west, I would lend you the money.

If you finished it in 3 minutes, I would give you my car.

4. 金牌特殊重點:!!

[簡單聯想記憶]:

下列動詞後的“賓語從句”中需要用虛擬形式,即should 動詞原形shoud在美國英語中要省略TOEFL語法考點)。此類常見的動詞有:order, ask, decide, demand, require, recommend, suggest(建議)insist(堅決要求),advise, etc.

例句:He suggested that we (should) help them with English.

The teacher ordered that the homework (should) be finished within half an hour.

 

● 下列名詞後的同位語從句要用“should 動詞原形”(should可省去)的虛擬

suggestion, order, request, demand, importance, proposal.

He made a suggestion that we (should) have a fancy dress party.

I think it is a thing of importance that it (should) be done soon.

 

● It is / was important / necessary / natural / essential / advisable / strange / surprising, ect. that 主語 should v.

It is strange that you should say such a thing.

It was important that you should tell me all the information.

 

wish後的賓語從句中,as if 後的狀語從句中,須用下列的虛擬形式

wish (that)did / were(指現在)

had done(指過去

would v.(指將來

I wish that I met my uncle now.

I wish I had met my uncle yesterday.

IwishI could meet my uncle tomorrow.

 

● It is (high) time that ... did / were ...

It is time that you went to bed.

 

would rather that ... did / were ...

I would rather that you were not here now.

 

would sooner that ... did / were ...
