虚拟语气的用法如何归纳

(1) I wish 句式:要表现与现在事实相反的欲望 , 从句谓语一般过去时或过去进行时 , 表现与过去相反的欲望 , 从句谓语用过去完成时或would / could+have +过去分词 , 表现将来没有把握或不太可能实现的欲望 , 用would (could)+动词本相 。如:
I wish I was ten years younger. 我但愿年青10岁 。
I wish I could speak your language. 但愿我能讲你们国度的话 。
I wish I hadn t wasted so much money. 但愿我没糟蹋这么多钱 。
(2) if only 句式:if only 与 I wish一样 , 也是表现与事实相反的欲望的 , 其后所虚拟语气的时态与 wish后所接时态的情形雷同 。如:
If only Tessa was here now. 要是特萨现在在这儿就好了 。
If only l knew the answer to your question. 我但愿知道你的问题的答案 。
(3) as if / as though 句式:以as if (as though)引诱的方法状语从句或表语从句 , 有时用虚拟语气 , 若表现与现在事实相反 , 谓语动词用一般过去时;若表现与过去事实相反 , 用过去完成时;表现将来的可能性不大 , 用would (might, could)+动词本相 。如:
I felt as if I was swimming. 我认为好像在游泳似的 。
At that time she acted as if I were her servant. 当时她的举止好像我是她的仆人 。
(4) it s time 句式:从句谓语通常用过去式表现现在或将来 , 有时也用过去进行时或 should+动词本相 (较少见 , 且should不能省略) , 其意为 (早)该干某事了。如:
It s time you washed those trousers. 你该洗洗那条裤子了 。
I m getting tired. It s time we went home. 我累了 , 我们该回家了 。
注:time前有时有about和high润饰:
It s high time we left. 我们早该出发了 。
(5) would rather 句式:通常用一般过去时表现现在或将来的欲望 , 用过去完成时表过去的欲望 。如:
I would rather you came tomorrow. 我情愿你明天来 。
I would rather you didn t mention the price. 我情愿你别提价格 。
