5.2017年高考英语词汇详解：persuade陷阱题解析

因为17年的计算量大。

数学题难度相当大，理综难度也超出了很多人的想象。物理大题的难度比较大，化学要比平时还要难，生物选修题考了平时很少复习的一个知识点。

所以当时很多同学的理综成绩都远远比不上平时的考试成绩。虽然说2019年的高考数学很难，但是其它科都还算简单，数学难度和2017年差不多，但是理综难度要偏简单，总的来看，2017年高考难度要偏难。

2017与2019年高考难度对比

2017年的难是有规律的难，出题都比较符合考生们平时的训练，只不过是难度稍微加大了一些。但是2019年高考就不一样了，它不但很难，而且还考了很多新题型。2017年，数学理综都比较难，数学的难度很大，理综的难度也不小，当时全省的理综的平均分都压得很低。

在2019年考试中，只有数学特别难，理综不算特别难，英语也还算简单，总体的难度不算高。但是有一点，2019年的考生数量要比2017年要多，竞争压力很大。从各种角度分析，2017年与2019年的难度相当。

　Once when I was facing a decision that involved high risk, I went to a friend. He looked at me for a moment, and then wrote a sentence containing the best advice I?ve ever had: Be bold and bre ? and mighty (强大的) forces will come to your aid.

　Those words made me see clearly that when I had fallen short in the past, it was seldom because I had tried and failed. It was usually because I had let fear of failure stop me from trying at all. On the other hand, whenever I had plunged into deep water, forced by courage or circumstance, I had always been able to swim until I got my feet on the ground again.

　Boldness means a decision to bite off more than you can eat. And there is nothing mysterious about the mighty forces. They are potential powers we possess: energy, skill, sound judgment, creative ideas ? even physical strength greater than most of us realize.

　Admittedly, those mighty forces are spiritual ones. But they are more important than physical ones. A college classmate of mine, Tim, was an excellent football player, even though he weighed much less than the erage player. ?In one game I suddenly found myself confronting a huge player, who had nothing but me between him and our goal line,? said Tim. ?I was so frightened that I closed my eyes and desperately threw myself at that guy like a bullet ? and stopped him cold.?

　Boldness ? a willingness to extend yourself to the extreme?is not one that can be acquired overnight. But it can be taught to children and developed in adults. Confidence builds up. Surely, there will be setbacks (挫折) and disointments in life; boldness in itself is no guarantee of success. But the person who tries to do something and fails is a lot better off than the person who tries to do nothing and succeeds.

　So, always try to live a little bit beyond your abilities?and you?ll find your abilities are greater than you ever dreamed.

　25. Why was the author sometimes unable to reach his goal in the past?

　A. He faced huge risks. B. He lacked mighty forces.

　C. Fear prevented him from trying. D. Failure blocked his way to success.

　26. What is the implied meaning of the underlined part?

　A. Swallow more than you can digest. B. Act slightly above your abilities.

　C. Develop more mysterious powers. D. Learn to make creative decisions.

　27. What can be learned from Paragraph 5?

　A. Confidence grows more rapidly in adults. B. Trying without success is meaningless.

　C. Repeated failure creates a better life. D. Boldness can be gained little by little.

　C

　The wallet is heading for extinction. As a day-to-day essential, it will die off with the generation who read print newspapers. The kind of shopping-where you hand over notes and count out change in return?now hens only in the most minor of our retail encounters，like buying a bar of chocolate or a pint of milk from a corner shop. At the shops where you spend any real money, that money is increasingly abstracted. And this is more and more true, the higher up the scale you go. At the most cutting-edge retail stores?Victoria Beckham on Dover Street, for instance?you don't go and stand at any kind of cash register when you decide to pay. The staff are equipped with iPads to take your payment while you relax on a sofa.

　Which is nothing more or less than excellent service, if you he the money. But across society, the abstraction(抽象) of the idea of cash makes me uneasy. Maybe I'm just old-fashioned. But earning money isn't quick or easy for most of us. Isn't it a bit incredible that spending it should hen in half a blink(眨眼)of an eye? Doesn't a wallet?that time-honoured Friday-night feeling of pleasing, promising fatness?represent something that matters?

　But I'll lee the economics to the experts. What bothers me about the death of the wallet is the change it represents in our physical environment. Everything about the look and feel of a wallet?the way the fastenings and materials wear and tear and loosen with age, the plastic and paper and gold and silver, and handwritten phone numbers and printed cinema tickets?is the very opposite of what our world is becoming. The opposite of a wallet is a smartphone or an iPad. The rounded edges, cool glass, smooth and unknowable as pebble(鹅卵石). Instead of digging through pieces of paper and peering into corners, we move our fingers left and right. No more counting out coins. Show your wallet, if you still he one. It may not be here much longer.

　28. What is hening to the wallet?

　A. It is disearing. B. It is being fattened.

　C. It is becoming costly. D. It is changing in style.

　29. What makes the author feel uncomfortable nowadays?

　A. Sing money is becoming a thing of the past.

　B. The pleasing Friday-night feeling is fading.

　C. Earning money is getting more difficult.

　D. Spending money is so fast and easy.

　30. Why does the author choose to write about what's hening to the wallet?

　A. It represents a change in the modern world.

　B. It has something to do with everybody's life.

　C. It marks the end of a time-honoured tradition.

　D. It is the concern of contemporary economists.

　31. What can we infer from the passage about the author?

　A. He is resistant to social changes.

　B. He is against technological progress.

　C. He feels reluctant to part with the traditional wallet.

　D. He feels insecure in the ever-changing modern world.

2017高考英语动词不定式专项知识点

一是选材丰富多用，渗透中外文化，助力文化品格培养，倡导科技，培育学生的情怀和国际视野，落实立德树人任务，体现学科核心素养的渗透。此次全国卷1高考英语试题的素材选材符合真实性强、时代性强、题材广泛、体裁多样、语篇典型、难度适合的原则。体裁覆盖了记叙文、说明文、议论文和应用文等四大文体。选用的语篇材料社会生活、历史文化、科普知识、饮食等，均和学生生活紧密相关。具体话题包括宣传手册（阅读A，介绍Pacific Science Center）、个人情况（阅读B，在野生动物救援和教育组织工作）、艺术与传承（阅读C，爵士乐）、科普知识与技术（阅读D，自制蒸馏器）休闲生活（七选五，露营体验）、学校生活（完形填空，在学校学习美式手语的事情）、饮食与健康（语法填空，在饮食中不能过少或过多摄入脂肪和盐分，两种情况对健康都不好）、难忘经历（短文改错，生日后期学车时的紧张心情）、传统文化推广（写作，教朋友Leslie学习汉语、唐诗）等话题，具有丰富的人文内涵、现实意义和育人价值。

二是倡导语篇能力，对语言知识运用、阅读理解及写作能力的考查均在语篇层次进行，注重综合运用能力的考核。各部分的任务兼顾真实性、实用性和趣味性，高度考查了学生的运用语言分析和解决问题能力。问题设置力求典型、规范，各部分考点设置分布合理，难度搭配适当，较全面地考查了学生应当掌握的基本语言技能以及各语言技能中包含的具体语言运用能力。命题语言（题目与选项）具有一定的难度，需要学生具有较高的解读（paraphrase）能力，能够反映一直以来高考全国卷的变化趋势。七选五侧重于对学生理解文章结构即文章内容连贯能力的考查，要求学生具有较高的语篇分析能力。

三是写作任务真实。2017高考英语写作是给朋友写信告知下次上课，题材是学生平时生活和学习中所熟悉的，又是学习和生活中用得上的，有很强的实用价值；同时具有很强的生活气息，突出了在生活中使用英语传递信息的必要性和真实性，充分体现了用英语做事的教学理念：将来无论在国内大学或者国外深造，导师与学生在很多时候都是用email联系、交流、布置任务。

语篇材料生词量与阅读量控制得当。2017年全国卷1阅读理解部分的总词量为1894词，文本长度为1436词，与2016年全国卷相比，要求接近（全国卷2007~2016年阅读理解总词量在1800~2000词之间，文本长度在1300~1400之间；其中全国1卷阅读理解长度为1914词，文本长度为1309词）。

完形填空考查学生在篇章层面综合运用背景知识、语言知识和逻辑判断等手段进行意义补全的能力，重点考查实词的用法。要求学生在掌握文章主旨大意和正确理解句与句、段与段之间的内在联系的基础上，准确判断动词、名词、形容词、副词等的意义和作用，语篇层面的考查要点占较大比例。

语法填空考点设置符合考纲要求以及课程标准所倡导的语言学习理念，在语篇层面上考查对语法知识掌握和应用的情况，不仅关注语言基础的词法和句法考查，还重视对语篇逻辑和意义连贯的判断，符合语言真实性的要求。与2016年全国卷1考点相比，此次没有考副词和代词，适当增加了主谓一致和形容词比较级，难度基本持平，答案保持了最大限度的唯一性，信度较高。

短文改错考点设置均为高中阶段学生学习英语过程中常犯的错误类型及项目，考点与考试大纲的样题及近年高考全国卷的考点相一致，对于词法、句法和行文连贯的考查分布合理，重视学生对于语篇的整体理解和逻辑判断。与2016年全国卷1考点相比，适当增加了序数词的考查。

书面表达对于部分写作内容有所限定（如学习内容和课前准备），以保证评分的效度，但对于时间和地点给予了半开放，对学习汉语、唐诗等的意义这些拓展则不作内容规限，保持一定开放性。写作任务对学生运用背景知识，合理拓展写作内容的能力要求比较高，任务能够充分考量学生就话题所表达内容的思想性、合理性和丰富度。

2017年高考英语词汇详解：persuade陷阱题解析

邪恶的机器(邪恶)的思想将推动军队的机器人杀手的好莱坞的理论是愚蠢的。真正的问题在于人工智能(AI)可能会变得非常擅长于实现某些东西，而不是我们真正想要的东西。在1960年,一个著名的数学家诺伯特·维纳,创立控制论领域(控制论),这么说:“如果我们使用,达到我们的目的,操作的机械机构与我们不能有效地干预(干预),我们最好是确定目的投入机器是我们真正的目的的欲望。”

具有特定目的的机器具有另一种质量，我们通常把它与生物联系在一起:希望保持它自己的存在。对于机器来说，这种质量不是与生俱来的，也不是由人类引入的;这是一个简单事实的逻辑结果，即如果机器死了，机器就无法达到它最初的目的。因此，如果我们送出一台带有“取咖啡”指令的机器人，它将有强烈的愿望，通过关闭自己的开关，甚至杀死任何可能干扰其任务的人，从而获得成功。如果我们不小心，那么，我们可能会面对一种国际象棋比赛，对手是非常坚定、超级智能的机器，它们的目标与我们自己的目标冲突，而现实世界则是棋盘。

进入和输掉这样一场比赛的可能性应该集中在计算机科学家的头脑中。一些研究人员认为，我们可以把机器密封在一种防火墙内，用它们来回答一些棘手的问题，但绝不允许它们影响现实世界。不幸的是，这个似乎不太可能奏效:我们还没有发明出一种安全的防火墙来对付普通人类，更不用说超级智能机器了。

在人工智能方面解决安全问题，似乎是有可能的，但并不容易。可能有几十年的时间来超级智能机器的到来。但这个问题不应该像某些人工智能研究人员那样被忽视。一些人认为，人类和机器可以共存，只要它们在团队中工作——但这是不可能的，除非机器能分享人类的目标。另一些人则说，我们可以“把它们关掉”，就好像超级智能机器太蠢了，不去考虑那种可能性。还有一些人认为超级智能的人工智能永远不会发生。1933年9月11日，著名的物理学家Ernest Rutherford满怀信心地说:“任何人都希望在这些原子的转变中，有一个力量的来源是月球上的光。”“然而,9月12日,1933年,物理学家Leo Szilard发明了中子诱发(中子诱导)核连锁反应。
