—Hello, Peter. I’m Bob. I just _________ on Monday.

A. start

B. have started

C. started

D. 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.

D. 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 trapping

B. have been trapped

C. were trapping

D. 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.

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.

7.【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

【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 repaired

B. is repaired

C. is being repaired

D. 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 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.

A. have developed

B. had developed

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.

12.【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

【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.

13.【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. )

14.【2018·海淀二模】13. —How was your vacation in Seattle?

64. is 65. than

66. that \which

67. causes 68. strength

69. energetic

70. it \running

【解析】本文是一篇说明文. 文章讲述了跑步的好处,它可以帮助人们延年益寿.

61. 考查副词的比较级. 医学报告显示:经常跑步的人比不跑步的人多活3年. 根据than 可知用比较级,故填longer.

62. 考查不定式作目的状语. 你不必跑地太快或时间太长就能看到它的好处. 此处不定式作目的状语,故填to see.

63. 考查动名词. 你也许喝酒、吸烟或超重,但仍然通过跑步会减少早亡的风险. 此处of 是介词,其后用动名词. 故填dying.

64. 考查动词的时态. 医学报告显示:跑步比散步、骑车和游泳更能有效地延长寿命. 这里叙述的是一个事实,故用一般现在时. 故填is.

65. 考查比较句型. 跑步比散步、骑车和游泳更能有效地延长寿命. 根据文章中的more effective可知此处填than.

点睛:本文比较难的一个题是10题. 短语give it a try不容易想出来. give a try试试. Give sb sth;give sth to sb这些短语学生都很清楚. 但give后加it或sth的形式,比较少见. 高考复习要尽可能多的复习相关的短语,尤其是用的比较多,而课本中出现较少的短语.

【2018·全国II】阅读下面短文,在空白处填入1个适当的单词或括号内单词的正确形式.

Diets have changed in China — and so too has its top crop. Since 2011,the country ___61___(grow)more corn than rice. Corn production has jumped nearly 125 percent over ___62___ past 25 years, while rice has increased only 7 percent.

A taste for meat is ___63___ (actual) behind the change: An important part of its corn is used to feed chickens, pigs, and cattle. Another reason for corn's rise: The government encourages farmers to grow corn instead of rice ___64___ (improve) water quality. Corn uses less water ___65___ rice and creates less fertilizer(化肥) runoff. This switch has decreased ___66___ (pollute) in the country's major lakes and reservoirs and made drinking water safer for people.

According to the World Bank, China accounts for about 30 percent of total ___67___ (globe)fertilizer consumption. The Chinese Ministry of Agriculture finds that between 2005—when the government ___68___ (start) a soil-testing program ___69___ gives specific fertilizer recommendations to farmers - and 2011, fertilizer use dropped by 7.7 million tons. That prevented the emission(排放) of 51.8 million tons of carbon dioxide. China's approach to protecting its environment while ___70___ (feed) its citizens "offers useful lessons for agriculture and food policymakers worldwide." says the bank's Juergen Voegele.

【答案】61. has grown

62. the 63. actually

64. to improve

65. than 66. pollution

67. global 68. started

69. that/which

70. feeding

【解析】本文是一篇说明文. 文中讲述了中国为保护环境在农作物种植上做了一些变化并得到了世界上的知名认识的认可.

61. 考查时态. since加时间点,主句要用现在完成时. 句意:2011年以来,中国种植的玉米比水稻多. 故填has grown.

62. 考查冠词. 句意:玉米产量在过去25年里增长了近125%,而大米只增长了7%. 故是特指在过去的25年里. 故填the.

67. 考查词性转换. 句意:中国约占全球化肥总消费量的30%. fertilizer consumption是名词短语,故应该用形容词修饰. 故填global.

68. 考查谓语动词. 句意:在2005年政府开始了一项土壤测试项目. 本句是when引导的定语从句,由于时间是2005年,故用过去时. 故填started.

69. 考查定语从句关系词. 根据空后的谓语动词gives可知,该空缺少主语,指代program并且引导后面的句子. 指物用that/which,故填that或者which.

70. 考查省略句. 句意:中国在养活了中国人民的同时又保护了环境. 这一做法为全世界的农业和粮食政策制定人提供了很有用的经验. 空格处表示正在进行的动作,while后面省略掉了China is,省略句的原则:在时间状语从句、条件状语从句、,让步状语从句中,如果从句的主语和主句的主语一致且含有be动词时,那么可以把主语和be动词一块省略. 故

、最值 一、选择题 1.(2017·全国甲卷理科·T11)若x=-2是函数f(x)=(2x+ax-1)1x e-的极值点,则f(x)的极小值为() A.-1 B.-23 e- D.1 e- C.53 【命题意图】导数研究函数的单调性,极值与最值以及不等式的解法.通过求极小值意在考查学生单调性与导数的关系,以及运算能力. 【解析】选A.由题可得f'(x)=(2x+a)1x e-+(2x+ax-1)1x e-=[2x+(a+2)x+a-1]1x e-, 因为f'(-2)=0,所以a=-1,f(x)=(2x-x-1)1x e-,故f'(x)=(2x+x-2)1x e-, 令f'(x)>0,解得x<-2或x>1,所以f(x)在(-∞,-2)和(1,+∞)上单调递增,在(-2,1)上单调递减,所以f(x)极小值=f(1)=(1-1-1)11 e-=-1. 【方法技巧】求可导函数f(x)的极值的步骤 (1)确定函数的定义区间,求导数f'(x). (2)求f(x)的拐点,即求方程f'(x)=0的根. (3)利用f'(x)与f(x)随x的变化情况表,根据极值点左右两侧单调性的变化情况求极值. 2.(2017·浙江高考·T7)函数y=f(x)的导函数y=f'(x)的图象如图所示,则函数y=f(x)的图象可能是() 【解析】选D.由导函数的图象可知函数在(-∞,0)上是先减后增,在(0,+∞)上是先增后减再增,故选D.

3.(2017·山东高考文科·T10)若函数g(x)=e x f(x)(e=2.718 28…是自然对数的底数)在f(x)的定义域上单调递增,则称f(x)具有M性质,下列函数中具有M性质的是() A.f(x)=2-x B.f(x)=x2 C.f(x)=3-x D.f(x)=cosx 【命题意图】本题考查函数的单调性的判断及导数的应用,意在考查考生应用已有知识分析问题、解决问题的能力. 【解析】选A.A中,g(x)=e x2-x= 2x e?? ???,因为 2 e >1,所以g(x)单调递增,所以f(x)具有M性质, 满足题意,故选A; B中,g(x)=e x x2,则g'(x)=e x x(x+2),所以g(x)在(-2,0)上单调递减,所以f(x)不具有M性质,不满足题意; C中,g(x)=e x3-x= 3x e?? ???,因为0< 3 e <1,所以g(x)单调递减,所以f(x)不具有M性质,不满足题 意; D中,g(x)=e x cosx,则g'(x)=e x(cosx-sinx),所以g(x)在 5 , 44 ππ ?? ? ?? 上单调递减,所以f(x)不具 有M性质,不满足题意. 二、填空题 4.(2017·江苏高考·T11)已知函数f(x)=x3-2x+e x-错误!未找到引用源。,其中e是自然对数的底数,若f(a-1)+f(2a2)≤0,则实数a的取值范围是. 【命题意图】考查利用函数性质解不等式,如何利用函数的性质把不等式转化为f(g(x))>f(h(x))的形式,根据函数的单调性去掉“f”,转化为具体的不等式(组)是重点.突出考查考生的应变能力. 【解析】因为f'(x)=3x2-2+e x+e-x≥3x2-2+2错误!未找到引用源。≥0,所以函数f(x)在R上单调递增,因为f(-x)

2018年高考语文真题分类汇编论述类文本阅读

2018年高考语文真题分类汇编论述类文本阅读 一、现代文阅读(共6题;共54分) 1.(2018卷Ⅰ)阅读下文,回答问题 诸子之学,兴起于先秦,当时一大批富有创见的思想家喷涌而出,蔚为思想史之奇观。在狭义上,诸子之学与先秦时代相联系;在广义上,诸子之学则不限于先秦而绵延于此后中国思想发展的整个过程,这一过程至今仍没有终结。 诸子之学的内在品格是历史的承继性以及思想的创造性和突破性。“新子学”,即新时代的诸子之学,也应有同样的品格。这可以从“照着讲”和“接着讲”两个方面来理解。一般而言,“照着讲”,主要是从历史角度对以往经典作具体的实证性研究,诸如训诂、校勘、文献编纂,等等。这方面的研究涉及对以往思想的回顾、反思,既应把握历史上的思想家实际说了些什么,也应总结其中具有创造性和生命力的内容,从而为今天的思考提供重要的思想资源。 与“照着讲”相关的是“接着讲”。从思想的发展与诸子之学的关联看,“接着讲”接近于诸子之学所具有的思想突破性的内在品格,它意味着延续诸子注重思想创造的传统。以近代以来中西思想的互动为背景,“接着讲”无法回避中西思想之间的关系。在中西之学已相遇的的背景下,“接着讲”同时展开为中西之学的交融,从更深的层次看,这种交融具体展开为世界文化的建构与发展过程。中国思想传统与西方的思想传统都构成了世界文化的重要资源,而世界文化的发展,则以二者的互动为其重要前提。这一意义上的“新子学”,同时表现为世界文化发展过程中创造性的思想系统。相对于传统的诸子之学,“新子学”无疑获得了新的内涵与新的形态。 “照着讲”与“接着讲”二者无法分离,从逻辑上说,任何新思想的形成,都不能从“无”开始,它总是基于既有的思想演进过程,并需要对既有思想范围进行反思批判。“照着讲”的意义,在于梳理以往的思想发展过程,打开前人思想的丰富内容,由此为后继思想提供理论之源,在此意义上,“照着讲”是“接着讲”的出发点。然而,仅仅停留在“照着讲”,思想便容易止于过去,难以继续前行,可能无助于思想的创新。就此而言,在“照着讲”之后,需要继之以“接着讲”。“接着讲”的基本精神,是突破以往思想或推进以往思想,而新的思想系统的形成,则是其逻辑结果。进而言之,从现实的过程看,“照着讲”与“接着讲”总是相互渗入:“照着讲”包含对以往思想的逻辑重构与理论阐释,这种重构与阐释已内含“接着讲”;“接着讲”基于已有的思想发展,也相应地内含“照着讲”。“新子学”应追求“照着讲”与“接着讲”的统一。 (摘编自杨国荣《历史视域中的诸子学》) (1)下列关于原文内容的理解和分析,不正确的一项是() A.广义上的诸子之学始于先秦,贯穿于此后中国思想史,也是当代思想的组成部分。 B.“照着讲”主要指对经典的整理和实证性研究,并发掘历史上思想家的思想内涵。 C.“接着讲”主要指连续诸子注重思想创造的传统,在新条件下形成创造性的思想。 D.不同于以往诸子之学,“新子学”受西方思想影响,脱离了既有思想演讲的过程。 (2)下列对原文论证的相关分析,不正确的一项是() A.文章采用了对比的论证手法,以突出“新子学”与历史上诸子之学的差异。 B.文章指出理解“新子学”的品格可从两方面入手,并就二者的关系进行论证。 C.文章以中西思想交融互动为前提,论证“新子学”“接着讲”的必要和可能。 D.文章论证“照着讲”“接着讲”无法分离,是按从逻辑到现实的顺序推进的。
