　　我希望我昨天遇上他了。(事实是昨天没有遇上) ③表示对将来情况的虚拟： wish ＋主语＋ would ＋动词原形。

　　I wish they would take me to London.

　　我希望他们会带我一起去伦敦。 (3)would rather引导的宾语从句，从句为过去时间，动词用had done; 从句为现在时间，动词用一般过去式(be用were)；从句是将来时间，动词用一般过去式。 I'd rather you came tomorrow.

　　我宁愿你明天来。 (不用would come, 用一般过去时came表示将来) 2．主语从句用虚拟语气的句式主要有3种： (1)在It is important/necessary that…等主语从句中，从句谓语动词用should＋动词原形。should此时表达“应该”的意思。 It is important that he (should) study hard.

　　他努力学习是很重要的。 (2)在It is amazing / strange / surprising / astonishing / a pity / a shame that从句中有时也用should，此时表示说话人的惊异、懊悔、失望等情感，常含有“竟然”之意。若不用虚拟语气则不带感情色彩，比较： It's a pity that he failed the exam.

　　他考试没及格，真是遗憾。 It's a pity that he should have failed the exam.

　　他考试竟没及格，真是遗憾。 (3)It is / was ordered / suggested / required / requested that从句中，从句谓语动词用should＋动词原形。should此时表达“应该”的意思。 It is suggested that you should phone before you go round there. 你去那儿之前应该先打个电话。 3.
