4、mportant/necessary/strange/impossible/natural that.”中，其中由 that 引导的主语从句通常用“should+ 动词原形”这样的虚拟语气，其中的 should 可以省略。故选 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 mi

5、stake.（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.

6、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。3wish 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

7、。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 cant find my purse.

8、超市了，但我不确定。根据句中时间状语 yesterday 可知，是对过去事情的推测，故用情态动词 + have done，再根据后句 but Im not sure.可知，此推测为不能肯定的推测，故用情态动词 could，表示“可能”。故选 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

9、 todays 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，

10、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

11、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。6.【2018天津】15. If we _the flight yesterday, we would be enjoying our holiday on the beachA. had caught B. caughtC. 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

12、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。 三、2017 年高考真题1.【2017北京卷】21. Samuel, the tallest boy in our class, _ easily reach the books on the top shelf.A. must B. should C. can D. need【答案】C试题分析：A. must 必须；B. should 应该；C. can 能；D. n

A. had been put B. were put C. should be put D. would be put【答案】A试题分析：句意：如果这个新的安全系统被投入使用过的话，这个事故就不会发生了。根据主句确定是对过去情况的虚拟，所以从句谓语用 had done

14、 形式，此外根据句意可知是被动，用被动语态，故 A 项是正确的。考点：考查虚拟语气。【名师点睛】英语中的三种语气，语气是动词的一种形式，用来说明我们对自己的话所采取的态度。1、陈述语气（疑问，否定，肯定，感叹）2、祈使语气（命令，要求，建议，警告）3、虚拟语气：不可能发生的事，愿望，建议，与事实相反的假设等.1、虚拟语气在条件中的具体用法真实条件句If you work hard,youll surely pass the exam.虚拟条件句（假设情况不存在，实现机会很小）If I were a bird, I could fly freely in the sky.3.【2017江苏卷】2

15、2. _ not for the support of the teachers, the student could not overcome her difficulty.A. It were B. Were it C. It was D. Was it【答案】B【解析】考查虚拟语气的省略。虚拟语气中，be 动词统一用 were；虚拟语气的省略形式主要是把 if 省略，if 从句的谓语动词 主句谓语动词1.与现在事实相反 动词过去式（be 一律用 were） would/could/might/should+动词原形2.与过去事实相反 had done would/could/might/

16、should+have done3.与将来事实可能相反 a.动词过去式（be 一律用 were）b.should+动词原形（不能用would）c.were to+动词原形would/could/might/should+动词原形同时把 were/should/had 提前，即 Were /Should/ Had I.，故选 B。【名师点睛】在虚拟语气中，be 动词只能用 were；虚拟条件句省去连词 if 时，从句主谓部分倒装：Were/Had/Should+主语+谓语动词.若条件从句为否定句，否定词 not 应置于主语之后，而不能与 were, should, had 等缩略成 Werent

17、, Shouldnt, Hadnt 置于句首。考点：考查虚拟语气和倒装4.【2017天津卷】2. My room is a mess, but I _clean it before I go out tonight. I can do it in the morning.A. darent B. shouldnt C. neednt D. mustnt【答案】C【解析】试题分析： 句意：我的房间很乱，但是在今晚我出去之前不需要打扫，我可以明天早晨再打扫。A.不敢；B.不应该；C 不需要；D.不许。根据句意，故选 C。考点：考查情态动词。【名师点睛】情态动词主要考查句意和说话人的语气的强弱，这几

18、个情态动词的否定形式意思各不相同，确定各自的含义，弄清它们的区别再结合上下文语境就不难理解了。 darent 通常表示“不敢”，shouldnt强调的是没有义务，必要性；neednt 表示“不需要” ，mustnt 表示不许，语气比较强烈，它们之间有明显不同。5.【2017天津卷】15. Do you have Bettys phone number?Yes. Otherwise, I _able to reach her yesterday.A. hadnt been B. wouldnt have been C. werent D. wouldnt be【答案】B【解析】试题分析：句意：你

19、有贝蒂的电话号码吗？有。否则我昨天就联系不到她了。此处 otherwise(否则)相当于一个 if 引导的条件状语从句，由 yesterday 可知本句对过去进行虚拟，由此可以判断出主句用wouldnt have done，故选 B。2016 年高考真题1.【2016北京】31.
