高中英语语法课件_虚拟语气(全)(共55张PPT)详解
解题思路
本题前半句是表示与过去事实相反的虚拟条件 从句,后半句是表示与过去事实相反的主句。 相当于:If he had worked harder, he would have got through the exams.本题的 答案是B. would have got through。 选项A. must have got through(肯定通过) 表示一种对过去事情的主观推测,不是与过去 事情相反的情况。另外,must不能用在虚拟条 件句中。 选项C. 和D. would / could get through (就会通过)是虚拟语气现在时的一种表示方 法,表示与现在事实相反。

祈使语气主要用于祈使句。 e.g. Get out of here! 虚拟语气
II. 什么是虚拟语气?
虚拟语气是一种特殊的动词形式,表示说话人 所说的话不是事实,而是想象、假设、建议、 打算、意见、愿望、怀疑、推测、喜悦等等。 e.g. If we had met her last night, we would have told her what had happened. 如果我们昨晚见到她,我们就会告诉她发生了 什么事。 (实际上,我们并没有见到她,也没有告诉她 所发生的事。)
注意!!!
如果条件从句是否定式,倒装时只能把 not 放在主语之后,不能用缩写式把not 放在主语之前。 e.g. Had you not told me about the matter, I should never have known the whole thing. (不能说:Hadn’t you told me…)
