2018年高考英语真题与模拟类编：专题02-动词的时态和语态及情态动词
2018年高考及最新模拟分类汇编之动词的时态和语态及情态动词2018年高考动词的时态和语态及情态动词1.【2018·北京】1. —Hi, I’m Peter. Are you new here? I haven’t seen you around?—Hello, Peter. I’m Bob. I just _________ on Monday.A. startB. have startedC. startedD. had started【答案】C【解析】考查时态。
句意：——嗨，我是彼得。
你是新来的吗？我没有在附近见过你。
——你好，彼得。
我是鲍勃。
我周一刚刚开始住在这儿。
根据两人谈话内容可知，Bob现在在这儿，他开始(start)住在这儿是发生在周一的事情，周一是一个过去的时间，故该句应用一般过去时态，C选项正确。
点睛：一般过去时表示过去某个时间里发生的动作或状态或过去习惯性、经常性的动作、行为。
一般过去时常与表示过去的时间状语或从句连用，如：yesterday，last week，in the past，in 2017，once，a few days ago等。
2.【2018·北京】4. Susan had quit her well-paid job and _________ as a volunteer in the neighborhood when I visited her last year.A. is workingB. was workingC. has workedD. had worked【答案】B点睛：过去进行时表示在过去某一时间段或某一段时间内正在发生或进行的动作或状态。
3.【2018·北京】7. China’s high-speed railways _________ from 9,000 to 25,000 kilometers in the past few years.A. are growingB. have grownC. will growD. had grown【答案】B【解析】考查时态。
句意：在过去的几年里，中国的高速铁路已经从9,000公里增长到25,000公里。
该句时间状语为in the past few years。
中国高速铁路的增长是从过去一直到现在几年里的情况，故该句应用现在完成时态。
B选项正确。
点睛：现在完成时可以表示过去的事情对现在的影响，也可以表示持续到现在的动作或状态，动词一般是延续性的。
常见的时间状语有：since + 时间点/从句，for two months，so far，recently，in the past/last few days等。
4.【2018·北京】9. A rescue worker risked his life saving two tourists who _________ in the mountains for two days.A. are trappingB. have been trappedC. were trappingD. had been trapped【答案】D【解析】考查语态和时态。
句意：一个救援人员冒着生命危险挽救了两个被困在山里两天的旅游者。
“who ___ in the mountains for two days”是定语从句，修饰two tourists，two tourists 和trap之间是被动关系，该空应用被动语态。
由risked可知，营救人员救游客是过去的事情，被困两天发生在营救人员救了他们之前，即“过去的过去”，该空应用过去完成时态。
综上，D选项正确。
点睛：过去完成时表示过去某一时间或动作以前已经发生或完成了的动作，即“过去的过去”，其表达形式为had done，被动语态的表达形式为had been done。
5.【2018·北京】12. In today’s information age, the loss of data _________ cause serious problems for a company.A. needB. shouldC. canD. must【答案】C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。
6.【2018·北京】13. They might have found a better hotel if they _________ a few more kilometers.A. droveB. would driveC. were to driveD. 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 f ound 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。
7.【2018·天津】15. If we ___________the flight yesterday, we would be enjoying our holiday on the beachA. had caughtB. caughtC. have caughtD. 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。
8.【2018·天津】13. My washing machine ___________this week, so I have to wash my clothes by hand.A. was repairedB. is repairedC. is being repairedD. has been repaired【答案】C【解析】考查时态。
句意：这周我的洗衣机正在修，所以我不得不手洗衣服。
根据后句so I have to wash my clothes by hand.可知，洗衣机正在修，故用现在进行时态的被动语态。
故选C。
点睛：本题考查时态。
分析选项可以知道，4个选项都用了被动语态，本题考查的其实是不同的时态。
选项A是过去时；选项B是一般现在时的被动；选项C是现在进行时；选项D 是现在完成时。
再结合语境进行分析，最终判断出最佳答案。
9.【2018·天津】10. I can't find my purse. I___________ it in the supermarket yesterday, but I'm not sure.A. should leaveB. must have leftC. might leaveD. 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。
10.【2018·江苏】31. Hopefully in 2025 we will no longer be e-mailing each other, for we _______ more convenient electronic communication tools by then.A. have developedB. had developedC. will have developedD. developed【答案】C【解析】考查时态。
句意：希望在2025年，我们不再互相发电子邮件，因为到那时候我们将开发更方便的电子通信工具。
根据时间状语in 2025，可知用将来时；再根据时间状语by then到那时，可知用完成时。
结合两者可知用将来完成时。
故选C。
点睛：本题考查时态。
句中包含的时间状语是解答此题的突破点。
所以要做好此类题，一定要注意题中有没有明确的时间点，或者其他可以代替时间点的词，所以根据时间状语可以看出正确答案。
本题的关键在于抓住题干中的两个时间状语in 2025和by then，从而得出答案。
11.【2018·江苏】30. I was sent to the village last month to see how the development plan_______ in the past two years.A. had been carried outB. would be carried outC. is being carried outD. has been carried out【答案】A【解析】考查时态。

根据句中时间状语last month和in the past two years可知用过去完成时。
故选A。

2018年高考英语一轮复习 语法专题 动词时态和语态(1)(讲)(含解析)新人教版必修3
动词时态语态复习（1）动词的时态和语态【高考考纲解读】时态与语态一直是热点，也是广大考生复习备考的难点。
考纲要求考生应该具备较强的语言应用能力，能在具体语境中恰当、准确地使用某一特定时态；熟练掌握常见的8种时态，同时还要熟练运用特殊时态句式和用法以及不用被动式但表示被动的动词和短语。
高考对时态的考查非常灵活且难度较大，不易把握。
大部分时态题答案的选择取决于题干语境；但也有部分时态试题较易把握，其用法相对固定，常见于特定句式结构中；还有部分常见时态用法特殊。
时态的考查主要集中在完成时，进行时等主干时态的掌握上。
要求学生熟练掌握几种主干时态的基本概念，解题时充分挖掘时间副词，短语，时间状语从句提供的信息。
在复习时态时应注意如下几点：⑴吃透语境，摸清作者的意图。
⑵准确判断动作和时间的关系。
（即动作是在什么时间发生的）⑶正确理解时间概念。
（大的时间：现在、过去、将来；小的时间：时间段，时间点，时间瞬间）⑷找准相关时态时间之间的交叉点。
例如：一般现在时，现在进行时（现在时间的交叉点）。
高考对被动语态的考查热点主要是及物动词在被动语态中的使用。
被动语态与主动语态一样，也有多种时态。
被动语态的完成时态和进行时态中，考生往往漏掉been或being。
因此被动语态的各种常用时态的构成，仍是高考命题的热点之一。
【重点知识整合】动词的时态一、一般过去时和现在完成时的用法区别1．一般过去时所表示的一个或一段过去时间是可以具体确定的，与其他时间没有牵连。
它所表示的事情纯属过去与现在情况没有联系。
现在完成时表示的事情发生在不能具体指出的现在以前的过去的某个或某段时间。
它所表示的事情与现在情况有关系，是过去事情在现在产生的结果或对现在的影响。
2．一般过去时常用的状语有yesterday, last night, two days (months, weeks) ago, at that time 等；现在完成时常用的状语有already, just (刚刚), yet, never, before 等；表示从过去延续到现在并包括现在在内的一段时间状语有：today, now, lately, recently, in the last / past few days / years (在过去的这几天/年里)。
2018版高考英语语法 动词的时态与语态
专题六动词的时态与语态考点一一般现在时①If you arrive，please give me a phone call.如果你到了，请给我打电话。
②I learned that the earth goes around the sun when I was in primary school.我上小学时就知道了地球围绕太阳转。
③Here comes the bus.公共汽车来了。
考点总结1．主要用来表示人、事物的现在状况和特点；表示经常或习惯性的动作，句子中常有often，always，from time to time等时间状语。
2．表示客观规律、事实和永恒真理。
3．在时间和条件状语从句中，代替一般将来时；常用的引导词有时间：when，until，after，before，as soon as，once，the moment/the minute，the day等；条件：if，unless，provided，so/as long as等。
4．用于here，there开头的倒装句中，一般现在时表示现在正在发生的动作或存在的状态。
考点二一般过去时①[2016·四川]Then，after two and a half years，the mother drove the young panda away.然后，两年半之后这位母亲赶走了熊猫宝宝。
②[2015·江苏]The real reason why prices were，and still are，too high is complex，and no short discussion can satisfactorily explain this problem.物价过去是，现在仍然是那么高的真正原因是复杂的，短时间的讨论不可能对此问题作出令人满意的解释。
③I always got up late，and never had enough time for breakfast.我总是起床很晚，从来没有足够的时间吃早饭。

2018全国高考汇编之动词时态与语态
2018全国高考汇编之动词时态与语态一（2018安徽卷）23．The twins, Who their homework, were allowed to play badminton on the playground.A. will finishB. finishC. have finishedD. had finished【考点】察看时态【答案】D【解析】句义：已经完成了他们的家庭作业，这对双胞胎被赞同在操场上打羽毛球。
依照句义可知他们完成作业是在被赞同到操场上打羽毛球从前。
而他们被赞同打羽毛球已经使用了一般过去时，因此完成作业应该使用过去完成时。
故D正确。

这里拿走发生在过去，重申对现在造成的影响，不知在什么地方，故用现在完成时。
二（2018北京卷）22. ---Hi, let’s go skating.--- Sorry, I’m busy right now. I _______ in an application form for a new job.A. fillB. have filledC. am fillingD. will fill【考点】察看时态【答案】C【解析】句意：—喂，我们五滑冰吧！—对不起，我现在很忙，我正在填写一份新的工作申请表。
依照句意可知本句是在表达说话时正在进行，正在发生的事情，因此使用现在进行时。
故C正确。
【试题延伸】时态题的察看要点是抓住句子的上下文含义和句中的时间状语。
