例如，“If he had known the answer, he would have told you.”这句话省 略了“he had known the answer”的部分，只保留了关键信息“he would have told you”，表示“如果他知道了答案，他会告诉你的”。

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。
为什么要学习虚拟语气？
虚拟语气是四级考试中重点考察的语法 点。历年四级考试中，仅仅单项填空部
分就一共出现了48道虚拟语气的题 目！！！
II. 虚拟语气的最基本形式
非真实性条件句是虚拟语气最基本的表 现形式。
i. 由“if” 来引导的非真实条件句

I.什么是语气？
语气是动词的一种形式，用以表示说话 人对某种言行或某种事情的看法或态度。 英语有三种语气：陈述语气，祈使语气 和虚拟语气。 陈述语气一般用来讲述事实或提出疑问。 常常用于陈述句、疑问句和感叹句。 e.g. I took a shower after supper. What are you going to do? What a beautiful flower!
