4.常用虚拟形式的句型
(1)从句中动词用过去式或过去完成式表示虚拟的句型：

had rather would sooner as if supposing…
If only… It is (high) time that…(从句中动词只用过去式)
如：

(2)If it were not for… (与现在事实相反)
If it had not been for… (与过去事实相反) 相当于but for。如：
If it had not been for his help (= but for his help), we would not have succeeded.
(3)If only…谓语动词视情况选用适当的形式。如：
If only the committee would approve the regulations and put them into effect as soon as possible.
(4)lest/for fear that/in case 从句谓语用(should+)动词原形。如：
The mad man was put in the soft-padded cell lest he injure himself.
(5)whether…or…有时谓语用be的原形，引导让步虚拟从句，这种用法经常采用倒装结构。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. |
