常用虛擬形式的句型
(1)從句中動詞用過去式或過去完成式表示虛擬的句型：
would rather would as soon as though suppose…
had rather would sooner as if supposing…
If only… It is (high) time that…(從句中動詞只用過去式)
如：His wife would rather they didn’t talk about the matter any more.

If I were in a movie, then it would be about time that I buried my head in my hands for a cry.

(2)If it were not for… (與現(xiàn)在事實相反)
If it had not been for… (與過去事實相反) 相當(dāng)于but for。如：
If it had not been for his help (= but for his help), we would not have succeeded.
(3)If only…謂語動詞視情況選用適當(dāng)?shù)男问?。如?BR> If only the committee would approve the regulations and put them into effect as soon as possible.
(4)lest/for fear that/in case 從句謂語用(should+)動詞原形。如：
The mad man was put in the soft-padded cell lest he injure himself.
(5)whether…or…有時謂語用be的原形，引導(dǎo)讓步虛擬從句，這種用法經(jīng)常采用倒裝結(jié)構(gòu)。如：
Church as we use the word refers to all religious institutions, be they Christian, Islamic, Buddhist, Jewish, and so on.
The business of each day, be it selling goods or shipping them, went quite smoothly.
