虚拟语气概念。虚拟语气是动词的一种特殊形式， 用来表达说话人的愿望，意图，建议，惊奇，设想等未能实现的情况，以及在说话人看来实现可能性很小的情况。II.虚拟语气的特点：1、虚拟语气表达的是与客观现实相反的观念。2、虚拟语气常由一个表示条件的从句和一个主句构成。3、由于虚拟语气中条件从句中的条件是与客观事实相反，因此其主句的结论也只能是想象的，非真实的。4、虚拟语气的特点决定了它句中动词形式的使用与真实句中的动词形式的是不同的。同时，虚拟语气受时间的制约，分成以下三种句式：1） 与现在事实相反的虚拟语气。2） 与过去事实相反的虚拟语气3） 与将来事实相反的虚拟语气III. 在不同时间下，虚拟语气的三种形式，公式。I.与现在事实相反 were might if+主语+ 过去式动词 would 过去式助动词 ， 主语+ could + V should II.与过去事实相反 might would + have + 过去分词If +主语+had +过去分词, 主语 + could Should III.与将来事实相反 were might if + 主语+ 过去式助动词 were to +v 主语+ would + V should + v. could 注：。虚拟语气中助动词be一律用were，不用was。在与将来事实相反的虚拟语气中，“if主语should +表示可能的假设1.与现在事实相反1)If I had a car, I should be very happy.= I should be very happy if I had a car, but I havent a car. 2)If I were a bird, I could fly. = I could fly if I were a bird, but I am not a bird, so I cant fly. 3)I he took his teachers advice, he might pass the exam. = He might pass the exam if he took his teachers advice, but he doesnt take his teachers advice, so he doesnt pass the exam. 4)If it werent raining, we should go for a picnic. = We should go for a picnic if it werent raining, but it is raining. 题例：1) If my father _ here now, he _ tell me what to do.

Its suggested that a modern hotel (should) be set up at the front of the hill. b. The general gave the order that the bridge (should ) be destroyed before 5 oclock in the morning. c. Its necessary /important that every party member (should ) take the lead and work well. 2)当suggest的主语不指人，而是指某一现象时，同时宾语从句不表示建议，而是暗示一种情况，这时宾语从句不用should +动词原形，而应根据内容而选择正确的时态。Insist等词的用法在不表示对未来某一动作的主张和要求时，也不用should +动词原形。例：a. The expression on his face suggested that he was unhappy. b. She insisted that her answer was right. 2.常见的要求使用虚拟语气的特殊动词， 词组，句形。1) about time should + V It + time + that +主语 high time V-ed例：a.
