虚拟语气的考查要点;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. ;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。;3.虚拟语气在主语从句中的运用。 在主语从句中，谓语动词的虚拟语气用“(should＋)动词原形”的结构，表示惊奇、不相信、理应如此等。 It is necessary (important, natural, strange, etc.) that we (should) clean the room every day. It was a pity (a shame, no wonder, etc.) that you (should) be so careless. It will be desired (suggested, decided, ordered, requested, proposed, etc.) that she (should) finish her homework this afternoon. ;用所给词的适当形式填空 (4)—Where are the children? The dinners going to be completely ruined. —I wish they (not be) always late. (5)It is requested that Class Two (give) a performance at the English evening. (6)He insisted that a deadline (set) for completing the task.;三、虚拟语气在其他场合的运用 1.虚拟语气在as if/as though, even if/even though等引导的表语从句或状语从句中，如果从句表示的动作发生在过去，用过去完成时；指现在状况
