一、虚拟语气在带有条件状语从句的复合句中的使用及其形式:
与现在事实相反:从句谓语用动词过去式(be 动词一般用were);主句用should, would, could, might等加动词原形。
If I were you, I shouldn’t do that.
We would go with you if we had time.
与将来事实相反:从句谓语可用动词过去式,should加动词原形或者用were to 加动词原形;主句谓语形式也是用should等助动词加上动词原形.
If it should rain, the crops would be saved.
If it were to snow tomorrow, they would not go out.
与过去事实相反:条件从句谓语用had加过去分词had+done;主句谓语是由should等助动词加have的过去分词组成. should/could/would +have+done
If he had seen you yesterday, he would have asked you about it.
If you e earlier, you might have met him.
I should / would have called you if I had known your telephone number.
混合虚拟条件句,,选用相对的虚拟形式.
If he had followed the doctor’s advice, he would be quite all right now.
If China had not been liberated, the working people would still be leading a miserable life now.
二、虚拟语气在主语从句中的应用:
句型一: It is necessary (important, natural, strange etc.) that…
是必要的(重要的,自然的,奇怪的)
句型二: It is a shame (a pity, no wonder, etc.) that…
惭愧(遗憾,不奇怪)
句型三: It is suggested (requested, ordered, etc.) that…
建议(要求,命令)
在这样的句型中,主句谓语动词的时态不限,从句谓语的虚拟形式一律是(should )+ 动词原形。其中should可以省去,但不能换would等别的助动词。
