Grammar 虚拟语气（The Subjunctive Mood）表示说话人所说的话不是事实，而是一种假设、愿望、怀疑或推测。虚拟语气主要用于条件从句、让步从句和名词性从句中。
（1） 虚拟语气在条件从句中的用法：
条件从句 表示现在情况 条件从句的谓语形式 If I(you, he /she, we, they) +动词过去式 If I(you, he /she, we, they) 表示过去情况 +had+过去分词 If I(you, he /she, we, they) +动词过去式 表示未来情况 If I(you, he /she, we, they) +should+动词原形 If I(you, he /she, we, they) + were to +动词原形 should/would/could/might +动词原形 主句的谓语形式 should/would/could/might +动词原形 should/would/could/might +have+过去分词 根据下面例句进一步理解：
① 与现在事实相反：
If I were you, I should do it in another way. 如果我是你的话，我会用另一种方法做。 ② 与过去事实相反：
If I had not studied hard , I would have failed in the exam. 假如我学习不那么刻苦，就不会通过那次考试了。 ③ 与将来事实相反：
If you missed(were to miss/should miss)the film tonight, you would feel
sorry for it.假如今晚错过了这部电影，你将会感到遗憾的。
（2） 虚拟语气在宾语从句中的用法：
①在wish后面的宾语从句中，谓语常用过去式来表示现在的情况，用过去完成时表示过去的情况，用would/could/might + 动词原形来表示将来的情况。如：
I wish that she were here with me and that we weren’t sick. I wish I had sent the old man to hospital in time. I wish I could be with you for the next three months.
would rather, as if, it’s time…, what if, if only也有类似用法
②在demand, suggest, order, propose, request, command, insist等动词后的宾语从句中，谓语通常用should + 动词原形或只用动词原形来表示愿望、建议、命令、请求等。
She suggested we (should) leave early.
The teacher insisted that the students (should) have a test.
