2、。其句子结构为宾语从句的谓语为would/could/might+动词原形。例：I wish I might be able to come tomorrow 。二、 用在一般虚拟条件句中的虚拟语气（一） 表示与现在、过去、将来事实相反的假设1 与现在事实相反的假设。其句子结构为：从句：if+主语+动词的过去式（be变were）+其他主句：主语+would(should, could, might)+动词原形+其他例：If I were you, I would go with him.2 与过去事实相反的假设。其句子结构为：从句：If+主语+过去完成时+其他主句：主语+should(woul

5、t week。4从句表示将来，主句表示现在。If we shouldn t have an exam this afternoon. I would go shopping now.三、 可以引起与事实相反的方式状语从句，用虚拟语气由as if、as though引起的与事实相反的句子，不论主句的谓语是现在时或者说过去时，其谓语表示的时间概念和句子结构，都基本上与wish后的宾语从句相同。例：John pretends as if he didn t know the thing at all, but in fact he knows it very well.(用过去式表示与现在事实相反的
6、假设)The old man looked at the picture, he felt as though he had gone back to time 20 years ago.（用过去完成式表示与过去相反的事实）They talked and talked as if they would never meet again (would+动词原形，表示与将来事实相反)四、在表示建议、命令、要求、忠告等动词的后面，其宾语从句的谓语用“should+动词原形”表示虚拟语气常用的此类动词有：表示“要求”的：ask, desire, request, demand, require, be
