(江苏专用)2017届高考英语二轮复习课件：第二部分专题六情态动词和虚拟语气

　　(1)基本用法

　　情况从句谓语动词主句谓语动词与现在事实相反过去式(be的过去式用were) should/would/could/ might＋动词原形与过去事实相反 had done should/would/could/ might＋have done 与将来事实相反过去式、 should＋动词原形、 were to＋动词原形 should/would/could/ might＋动词原形 ①If I were you，I would do it another way. If I saw her now，I would be very happy. ②If he had taken my advice，he should have succeeded in the competition. ③If he should come here tomorrow，I should/would talk to him. If it were to rain tomorrow，the football match would be put off. (2)含蓄虚拟语气有时非真实条件不是通过if引导的条件来表现的，而是通过一些词或短语来表示，如without，but for，otherwise，but等。 ①I couldn't have finished the work on time without your help. ②But for your timely warning，we would have got into great trouble. (3)非真实条件句省略if的用法如果非真实条件句中有had，were，should，就将had，were，should提前形成部分倒装，条件句中的if可以省略。 ①Had he taken my advice，he would not have made such a mistake. ②Should it be sunny tomorrow，we would go hiking. ③Were there no air or water，there would be no living things on the earth. (4)在“suggest，order，demand，propose，command，request，require，insist，desire，urge，recommend”等动词的宾语从句以及would rather后，要用“(should＋)动词原形”来表示愿望、建议、命令、要求等；由上述动词派生或转化的名词的同位语从句或表语从句中也要用相应的虚拟形式。 ⊙怎么考在语篇中考查：1.情态动词的基本用法(情感、态度和推测)；2.某些情态动词的“偏义”用法，如：shall，must，won't等；3.虚拟语气的考查。 ⊙怎么学在平时的阅读与学习中，注意情态动词的基本用法，掌握虚拟语气的句型公式。 ⊙怎么解细心体会上下语境，把握作者或语篇中人物的情感态度，然后确定情态动词的选择。
