区别: 虚拟语气 Subjunctive Mood 非典型性虚拟语气 类型一 would (had) rather, would as soon, would sooner和would prefer所引起的从句中要求用过去式表示当时或将来的情况，用过去完成时表示过去的情况，表示希望或婉转的责备。例如：  类型二 （4）It’s (high, about) time that 句型中that从句中要求用虚拟语气形式，即动词要用过去式。 It’s time that something was done about the traffic problem downtown. It is high time that we ? put an end to this discussion.现在是我们该结束讲座的时候了。 类型三 （6）由连接词in case, so that ,unless, lest （唯恐，以免）,for fear that引起的状语从句中，谓语动词要用虚拟形式，即should(might, would)+动词原形，例如： She put a blanket over the baby for fear that he should catch cold. 她在那个婴儿身上盖上了毯子以免他着凉。 The bad man was put in the safe cell lest he injure himself.  类型四 if it were not for…与现在事实相反， if it had not been for与过去事实相反，两个都相当于but for： If it had not been for his help(=but for his help),we would not have succeeded.  类型五 虚拟语气用于as if（though）引起的方式状语从句和表语从句中，其动词形式与wish宾语从句的形式相同。例如：She often laughs spontaneously（不由自主地）, and her good humor（好心情） breaks out as brightly as if it were a part of the sunshine above.她常常发出发自内心的微笑，而且她那美好的情绪像天上一道明亮的阳光一样，常常流露出来。 They talked as if they had been friends for years.他们交谈着，就好像他们是我年的老朋友一样。 She looks as if she would cry.她看起来好像要哭了。  类型六 if it were not for…与现在事实相反， if it had not been for与过去事实相反，两个都相当于but for： If it had not been for his help(=but for his help),we would not have succeeded.  类型一 虚拟语气的特殊形式，即用来表示要求、建议、命令、提议、意愿等的主语从句、宾语从句、表语从句和同位语从句中的虚拟形式，其虚拟语气的构成往往是由should(可省略)+动词原形that从句。 A、 用于表示意愿、建议、命令、提议、请求等动词后的that宾语从句中，这类动词有：  If you ? ? ? that late movie last night, you wouldn’t be so sleepy. A. haven’t watched ? ? B. didn’t watch ? ? C. hadn’t watched ? ? D. wouldn’t have watched ? Many dead would now be alive if they have not attempted to return for something.  Had Paul received six more votes in the last election, he would be our chairman now.  混合虚拟语气还有一种情况就是事实和虚拟假设的混合句，这样的句子不仅仅是时间的不同，而重要是事实和假设的混合。  含蓄条件句是指句中没有明显的虚拟条件句，而是利用其他手段来暗示存在虚拟条件。但是这类隐含式虚拟条件句往往都可以转化为if引导的条件句。常来表示含蓄虚拟条件的手段有： （1）介词或介词短语，如but for, but that, without, in case of
