3、虚拟语气在状语从句中的用法
(1)在带有even if/ even though引导的让步状语从句的主从复合句中,主句和从句都用虚拟语气,动词形式与含有非真实条件句的虚拟语气相同。如: Even if he had been ill, he would have gone t his office. 即使生了病,他俩去办公室。
(2)由as if或as though引导的状语从句表示比较或方式时。从句谓语形式为动词的过去式(be用were)或 “had十过去分词”。如: He treated me as if I were a stranger. 他那样对待我,好像我是陌生人似的。She talked about the film as if she had really seen it. 她谈论那部影片,就好像她确实看过一样。
注:如果表示的事情可能会发生,那么方式状语从句中的谓语动词可用陈述语气。
(3)在in order that或so that引导的目的状语从句中,谓语动词多用 “could或might(有时也用should)+ 动词原形”。如: Mr green spoke slowly so that his students could (might) hear clearly. 格林先生说得很慢,好让学生听清楚。
4、虚拟语气在定语从句中的用法:在"It is time (that) …"句型中,定语从句的谓语动词常用虚拟语气表示将来,动词形式一般用过去式,意思是"该干某事的时候了"。如: It’s (high) time we did our homework. 我们该做作业了。
5、虚拟语气在简单句中的用法
(1)情态动词的过去式用于现在时态时,表示说话人的谦虚、客气、有礼貌,或委婉的语气,常见于日常会话中。如: It would be better for you not to stay up too late. 你最好别太晚睡觉。
(2)在一些习惯表达中。如: I would rather not tell you. 我宁愿不告诉你。
(3)用“may + 动词原形”表示"祝愿"、"但愿”,此时may须置于句首(多用于正式文体中)。如:May you be happy!祝你快乐!May good luck be yours.祝你顺利。
