1、小小顺口溜
虚拟语气并不难, 从句时态都提前,
主句would加在前,注意动词要还原。
(省略if要倒装)
.
1)If I were in your shoes, I would accept the terms.
2) If we had left earlier, we wouldn’t have missed the train.
3) I wish I were as clever as you

①此表中需要注意几点:
。在非正式情况下,第一、第三人称后偶尔也用was。如:
If he were/was you, he would go at once.

,would, could以及might可以用于各种人称。
,只能用should,而不能用would, could和might等。如:
If it should rain tomorrow, we would not go camping. (should rain也可以用rained, were to rain代替)

②含蓄条件句
有时为了表达的需要,在虚拟语气中并不总是出现if引导的条件句,而通过其他手段来替代条件句。
。常用介词有with, without, but for等。如:
We couldn’t have eeded without your help(=If we hadn’t got your help).
What would you do with a million dollars?
But for the rain(=If it hadn’t been for the rain), we would have finished the work.

1)He would have given you more help, but he has been ill.
2)I was ill that day. Otherwise I would have taken part in the parade.( if I hadn’t been ill,…)
★but, otherwis
