Subjunctive Mood (2) Unit 2 Grammar 在上一单元中我们学习了虚拟语气(和现在、过去、将来事实相反)的用法。在本单元中我们将复习上一单元所学内容、引申一些新知识并通过练习进一步加深理解。 To learn more about the subjunctive mood and use it properly. 语法讲解建议采用归纳法，如尽可能多的呈现一些相关例句，或可让学生从已学课文中找相应例句，引导学生试着从所观察到的语言现象中总结出语言规则和语法规律。 Let’s look at this poem. Our first football match We would have won … if Jack had scored that goal, if we’d had just a few more minutes, if we had trained harder, … We would have won … if we’d been better! This poem contains sentences in the subjunctive mood. 虚拟语气  1）概念 虚拟语气用来表示说话人的主观愿望或假想，所说的是一个条件，不一定是事实，或与事实相反。 2）在条件句中的应用 条件句可分为两类，一类为真实条件句，一类为非真实条件句。非真实条件句表示的是假设的或实际可能性不大的情况，故采用虚拟语气。 在条件状语从句和结果状语从句中,表示 与事实相反的条件和结果。 1) 与现在事实相反： If 主语 …, 主语 +V原 was/were /V-ed should (would could, might) 2) 与过去事实相反： If 主语 , 主语 +have V-ed 3) 与将来事实相反： If 主语 …, 主语 +V原 should (would could, might) should were to should (would could, might) had been /V-ed 假设条件从句谓语动词发生的时间与主句所假设的谓语动词不一致，叫做错综条件虚拟语气(mixed conditionals)。主句和从句的谓语动词要依照假设的时间而定。 If the weather had been finer, the crops would be growing still better. If you had followed the teacher’s advice, you wouldn’t be in the hospital. 1. We use mixed conditionals when the main clause and the if-clause are about different tenses. e.g. If you had come and attended the meeting yesterday, you would know what we are doing now. If you had followed my advice, you would not be in trouble now. 2. We use otherwise, or and phrases beginning with with, without and but for to replace an if-clause in implied conditionals. Without air , there would be no living things. But for your help , I couldn’t have done it. (If there were no air) (If it hadn’t been for your help) I was busy that day. Otherwise I would have gone there with them. (I
