新课标2016届英语语法总复习课件 专题八：情态动词和虚拟语气.ppt

(15)The door open, no matter how hard Grandma pushed. 解析　句意：无论Grandma如何推，门总是打不开。will表示某种倾向或习惯性动作，意为“总会，老是”，其否定为“不能，不肯”，在此是过去时态，故用“wouldn‘t”。 wouldnt 虚拟语气的考查要点 一、虚拟语气用于条件状语从句 1.表示与现在事实相反的假设，条件状语从句中的谓语动词用一般过去时(be动词用were)，而主句中的谓语动词用“would/should/could/might＋动词原形”。 If I were you, I would buy that house. If he had time, he should go with you. 2.表示与过去的事实相反，条件状语从句中的谓语动词用过去完成时，主句中的谓语动词则用“would/should/might/could＋have＋过去分词”。 If he had taken my advice, he would have succeeded in passing the examination. 3.表示与将来事实相反，条件状语从句中的谓语动词用一般过去时或“should/were to＋动词原形”，而主句中的谓语动词则用“would/should/could/might＋动词原形”。 If it were to rain tomorrow, the football match would be put off. 4.当条件状语从句表示的行为和主句表示的行为所发生的时间不一致时，动词的形式要根据它所表示的时间作相应调整。 If they had worked hard, they would be very tired now.(从句说的是过去，主句指的是现在) 用所给动词的适当形式填空 (1)If I (have) time next week, I would go to the party. (2)If I (be) you, I should go and see the dentist at once. (3)If you had arrived at the station ten minutes earlier, you (catch) the train. had were would have caught 二、虚拟语气用于名词性从句 1.虚拟语气在宾语从句中的运用。 (1)“wish＋宾语从句”表示不能实现的愿望，译为“要是……就好了”等。表示现在不能实现的愿望，从句中的谓语动词用一般过去时；表示将来不能实现的愿望，从句中的谓语动词用“would/could＋动词原形”；表示过去不能实现的愿望，从句中的谓语动词用“had＋过去分词”或“could/should＋have＋过去分词”。 I wish it were spring all the year round. I wish I had known the answer. I wish I could fly like a bird. (2)在表示建议、要求、命令等动词后的宾语从句中，谓语动词用“should＋动词原形”，should可以省略。 常见的动词有： suggest, advise, propose, demand, require, insist, request, command, order等。 She suggested we (should) leave here at once. The doctor ordered she should be operated on. suggest除了“建议”外，还有“暗示，表明”的意思，若当“暗示”时，suggest后跟陈述语气。 insist当“坚持主张、要求”时后跟虚拟语气；若当“坚持一说法、事实”时，后用陈述语气。 2.虚拟语气在同位语从句和表语从句中的运用。 表示建议、要求、命令等的名词，如advice, idea, order, demand, plan, proposal, suggestion, request等，其后的表语从句和同位语从句中谓语动词用“(should)＋动词原形”， should可以省略。 His suggestion that we (should) go to Shanghai is wonderful. My idea is that they (should) pay 100 dollars. 3
