‎2018年高考题 ‎1.【2018·江苏】24. It’s strange that he _______ have taken the books without the owner’s permission.‎ A. would B. should C. could D. might ‎【答案】B 点睛:本题考查虚拟语气。It is important/necessary/strange/impossible/natural that... 主语从句多数情况下用虚拟语气,表达一种要求、命令或者责备、建议或主观看法。但是如果只是表示陈述一个事实而不是强烈的感情,完全可以用一般的陈述语气。试比较: It is strange that he had made a mistake.(陈述一个事实:他犯了错误让人有点奇怪。) It is strange that he (should) have made a mistake. (虚拟语气,说话者是在责备他本不应该犯错。)‎ ‎2.【2018·江苏】27. There is a good social life in the village, and I wish I _______ a second chance to become more involved.‎ A. had B. will have C. would have had D. have had ‎【答案】A ‎【解析】考查虚拟语气。句意:在这个村里有很好的社交生活,并且我希望我再有机会去更多的参与。本题考查wish引导的宾语从句,表示与现在事实相反的愿望,所以从句用一般过去时。故选A。‎ 点睛:本题考查wish引导的虚拟语气。由wish引起的表示愿望的虚拟语气:1.用wish表示对现在的愿望时,它所引起的宾语从句中谓语动词形式为:过去式(be动词用were)。2.用wish表示对将来的愿望时,它所引起的宾语从句中谓语动词形式为:would, could,‎ ‎ might+ 动词原形。3.wish用于对过去的事实表示一种不可能实现的愿望时,宾语从句中的谓语动词形式为:had+动词过去分词或could, would + have +动词过去分词。分析此题需抓住前句There is a good social life in the village的时态是一般现在时,可以判断出此题wish用于对现在的事实表示一种不可能实现的愿望。‎ ‎3.【2018·天津】10. I can't find my purse. I___________ it in the supermarket yesterday, but I'm not sure.‎ A. should leave B. must have left C. might leave D. could have left ‎【答案】D 点睛:情态动词是每年高考的热点也是难点。本题抓住两点:第一、时态。根据句中时间状语可以判断出是对过去事情的推测,故用情态动词 + have done;如果是对现在事情的推测,才用情态动词+v原形。第二、情态动词的选择。must为肯定推测,表示“一定”,could为不肯定推测,表示“可能”,这样就能选出正确答案。‎ ‎4.【2018·北京】12. In today’s information age, the loss of data _________ cause serious problems for a company.‎ A. need B. should C. can D. must ‎【答案】C ‎【解析】考查情态动词。句意:在今天的信息时代,数据的丢失有时会对一个公司造成严重的问题。数据丢失造成严重问题是客观上会发生的情况,即“客观可能性”,故该空应用情态动词can。C选项正确。其余情态动词均没有该用法。need需要;should应该,竟然;must必须,肯定。‎ 点睛:can的基本用法:1. (表示能力、功能)能,会;2. (表示推测)可能,可能会;3.(表示允许,请求)可以;4.(表示客观可能性)有时会。‎ ‎5.【2018·北京】13. They might have found a better hotel if they _________ a few more ‎ kilometers.‎ A. drove B. would drive C. were to drive D. had driven ‎【答案】D ‎【解析】考查虚拟语气。句意:如果他们多开几公里的话,他们也许会找到一个更好的旅馆。由“they might have found a better hotel”可知,该句是表示对过去的虚拟。if ____ a few more kilometers是条件句部分,表示对过去的虚拟,条件句部分要用过去完成时态,故D选项正确。‎ 点睛:1. 表示对现在的虚拟:if条件句用一般过去时,主句用would/might/could/should+do;2. 表示对过去的虚拟:if条件句用过去完成时,主句用would/might/could/should+have done;3. 表示对将来的虚拟:if条件句用were to do/should do/一般过去时,主句用would/might/could/should+do。‎ ‎6.【2018·天津】15. If we ___________the flight yesterday, we would be enjoying our holiday on the beach A. had caught B. caught C. have caught D. would catch ‎【答案】A ‎【解析】考查虚拟语气。句意:如果我们昨天赶上飞机的话,现在我们正在海滩享受我们的假日了。根据时间状语yesterday可知,从句表示与过去事实相反,故用had + v-ed。故选A。‎ 点睛:本题考查虚拟语气。虚拟语气重要做题原则:根据题干中主句或从句中动词形式判断所考查的动词的虚拟时间,一般要保持一致,但要注意错综时间虚拟语气要根据各自所表示的虚拟时间做出调整。本题就是错综条件虚拟语气,从句与过去事实相反,故用had + v-ed,主句与现在事实相反。‎ ‎2017年高考题 ‎【2017·北京卷】21.

It were B. Were it C. It was D.
