3、ards science education.7.And I wish they would decrease the size of classes.8.My wife often wishes that I had chosen a job with less stress but I love what I do.1.1、2、3 句表示与过去事实相反的虚拟语气，其条件从句用 had done，主句谓语用 would have done。2.在 wish 后面的宾语从句中，表示与现在事实相反的愿望的是 4 句和 7 句，表示与过去事实相反的是 8 句。3.5 句和 6 句中用 should

4、 have done 结构表示“过去本该做某事而实际未做” 。虚拟语气常表示某种情况与事实不相符或表示说话人的愿望、请求、意图、建议、惊奇或设想等。它常用于非真实条件句中，根据其表达的时间不同主从句的虚拟结构也有所不同。一、虚拟语气在非真实条件句中的使用时间 从句谓语 主句谓语与现在事实相反动词的过去式(be 动词的过去式通常用 were)would/could/should/might动词原形与过去事实相反 had过去分词 would/could/should/mighthave过去分词与将来事实相反动词的过去式；should动词原形；were to动词原形would/could/shoul

6、间使用不同的动词形式。If he had joined the army thirty years ago，he would be a general now.如果 30 年前他参了军，他现在就是将军了。(从句表示与过去事实相反的假设，主句则表示与现在事实相反的假设。)三、含蓄条件句1.非真实条件句中的条件从句有时不表示出来，只暗含在上下文中，如用 but for，without， with，otherwise，or 等词语。Given more time，he could have done it better.再多给点时间他可能会做得更好。Without your help，we coul

7、dnt have finished our work on time.没有你的帮助，我们不可能按时完成我们的工作。2.有些句子没有任何表示条件的单词、短语或句子，但意义隐含在上下文中，所以它们也需要用虚拟语气。He told me about your coming，or I would have known nothing about it.他告诉我你来了，否则我就一无所知了。四、虚拟条件句的省略和倒装当虚拟条件从句中含有 were，had，should 时，可以省去 if，而将它们移到从句句首构成倒装结构。If I were in your place，I wouldnt do that.
