目录2018年北京英语高考题 2018年英语高考真题 2018北京英语高考答案解析 2018北京卷阅读理解D篇解析 2018年北京卷完形填空答案
首先，文本选自洛杉矶时报http://www.latimes.com/opinion/editorials/la-ed-autonomous-vehicles-planning-20180309-story.html 2018年3月9日发表的名为If we don't plan for them, autonomous vehicles could make our car-dominated transit system even worse的文章。
看原标题可以得出几个信息：1.目前有plan，2.car−dominated transit system是关键问题3.even worse，也就是有前提条件，然后才可能出现某种预期。
这篇阅读理解试题选文的特点是，1.文章是国外主流媒体新近更新的文章，相对于高考日期来说是比较新的。2.题材相对比较前沿——关于无人驾驶汽车。相对来说的新科技话题，具有一定的信息引领性。同时，无人驾驶也是目前比较有争论的话题，所以任何一篇文章都不会完全从某一个角度独立来分析阐述这一现象，除非绝对的专业测评或者技术等视角，普通评论或者描述文章一定都会有或多或少的利弊分析，因为这是未知因素会有所影响的一个话题。本文也不例外，但是本文经过改编后明显把话题倾向性定位在positive 上，整体看不出明显的问题，但是会有对客观事实的微小不尊重。这是从阅读理解试题选文的真实性信息来考虑的。本文读者受众没有刻意的区分和归类以及倾向性，文章也不算纯粹的科普文，属于普通的说旅携前事文吧，依然是侧重introduce and describe ，因为没有明显的正反观点的对比，文中对比主要体现在现象的比较，所以涉及argumentation 的成分很少。基于此，本文的行文，正常来说要围绕提出问题——分析问题——解决问题来进行。
试卷文本和原文比较有大量删减改编。
首先看改编后的标题Preparing Cities for Robot Cars关键信息定位在preparing cities。但是我们在正文当中是否能够找到关键信息来支持标题核心信息，我认真阅读后，还是不明朗。但拆清是原选文标题比较符合原选文的核心内容。而且此标题从语言角度来说也不好理解，所以标题不做更多解释。
（2018•北京）阅读理解D
标题Preparing Cities for Robot Cars
试题文章第一段
原本想和原文比较一下改动部分，但是改动太大，就省略了吧，很明显感觉改动得不是很好。比如prospect被替换为possibility 这个在理解文本含义上可以理解，但是假如作为精读去点对点分析，就会不如原词汇那么妥帖，我只能用这个词隐谈来形容。看prospects词汇解释：
以此例来说明改编的可能的不准确性，文本下面部分的改编的类似问题不再重复说明。
The possibility of self-driving robot cars has often seemed like a futurist's dream, years away from materializing in the real world. Well, the future is apparently now. 开篇点“题”，把无人驾驶汽车的现存状态通过一个语义对比句展示出来。告知读者本文是围绕无人驾驶汽车现状的某个问题阐述的。接下来的test，cleared the way 暗示一是有测试环节，二是有相关辅助环节。
California, it should be noted, isn't leading the way here. Companies have been testing their vehicles in cities across the country. 这是本文中围绕标题而出现的最重要的关键信息。暗示cities在无人驾驶领域所可能做出的贡献。
But however long it takes, the technology has the potential to change our transportation systems and our cities, for better or for worse, depending on how the transformation is regulated.
此处有本文的一个题点关键词regulated，提示regulation 对于无人驾驶未来走向的重要性。看48题：
As for driverless cars, what is the author's major concern?
A. Safety.
B. Side effects.
C. Affordability.
D. Management.
题干部分有关键信息词author ，major 所以就限定是本文作者的重点的……关注点，所以需要透彻理解本文所传递的信息是什么，还要结合选项内容来看。同时结合原文看，本文是把safety 部分内容删除掉了，而我们看四个选项事实上都可以，四个选项和客观真实性是保持一致的，至于本试题当中认为限制答案为D，从做题角度会有很多解释，但是这样的试题不严密，且，好的试题不会用major来限定。
第二段
While much of the debate so far has been focused on the safety of driverless cars(and rightfully so), policymakers also ……段首用了一个暗含转折，实际上是语义的一个侧重“确定”的句子，使用了while …also表达，前后两者都存在，但是此处侧重强调后者的意思。那么也就是说safety 问题是现存的一个相关焦点，但是这里作者想要强调also后面的内容。所以，从全文角度看，经过改编的文本有了作者或者文章态度上的些许不同，本段和原文比较有部分词汇改编删减，但是基本符合要求，没有大的变化。
接下来的内容作者具体描述无人驾驶汽车的优势和特色，包括停车管理，环境保护，以及和出租车公司等相比较的更多的便利，原文提到了优步等出租公司的disadvantageous ，但试题文本有删减，所以个别信息在理解上会觉得有模糊的感觉，不透彻。本段结束。
在此，我们就可以暂停，看试题：
47.According to the author, attention should be paid to how driverless cars can __________.
A. help deal with transportation-related problems
B. provide better services to customers
C. cause damage to our environment
D. make some people lose jobs
题干中使用了pay attention to ，而这个题干是完全可以修改成一个更地道的句子的，也可以是问答方式，不是填空式。重点又在author 和attention 来限定信息，也就是可以推测，题目需要做答的是作者在本文中想要表达的观点，那么根据文本内容，c项是可以否定的。abd都不是可以完全限制的信息，也就是都有可能性，只是a项更符合出题人的思路，所以答案是A。
接下来看下一段内容，
Do we want to copy — or even worsen — the traffic of today with driverless cars? Imagine a future where most adults own individual self-driving vehicles. They tolerate long, slow journeys to and from work on packed highways because they can work, entertain themselves or sleep on the ride, which encourages urban spread. They take their driverless car to an appointment and set the empty vehicle to circle the building to avoid paying for parking. Instead of walking a few blocks to pick up a child or the dry cleaning, they send the self-driving minibus. The convenience even leads fewer people to take public transport — an unwelcome side effect researchers have already found in ride-hailing(叫车) services.
段首一句属于段落衔接句，用设问的形式引出来。一方面提示读者思考，给出自己的思维判断，同时引出下面作者想要陈述的内容，此句看关键词worsen ，也就是说，作者暗示的观点是现有的交通的诸多不利因素，对于无人驾驶汽车来说会是什么样的一种对比分析结果呢？而通过上文中作者的情感态度，大致可以判断，下文作者想要阐述的是如何规避现有交通的不利因素。通过阅读试卷上的文本，我感觉此段信息和句首信息不一致，而且不符合常理，所以我再次查阅原文，因为在手机上编辑，顺便简单截图一下，如下：
通过阅读原文，可以了解，此处被命题人删除掉了，但是此举就完全改变了文章的行文思路和意义的正常表达。因为在提到了无人驾驶汽车的优势以后，作者做了一个imagine ，也就是假想内容，而此假设导致的结果就是满街的无人驾驶汽车，而此句也被命题人删除了，但是这些信息是非常关键的信息，是管理者要解决无人驾驶汽车所要面对的关键问题，删除后，就不能体现初衷含义了，而且阅读时会晦涩，不能够真正表达真实场景。具体语言不做分析解释，接下来看下一段，
A study from the University of California at Davis suggested that replacing petrol-powered private cars worldwide with electric, self-driving and shared systems could reduce carbon emissions from transportation 80% and cut the cost of transportation infrastructure(基础设施) and operations 40% by 2050. Fewer emissions and cheaper travel sound pretty appealing. The first commercially available driverless cars will almost certainly be fielded by ride-hailing services, considering the cost of self-driving technology as well as liability and maintenance issues(责任与维护问题). But driverless car ownership could increase as the prices drop and more people become comfortable with the technology.此段因为删除掉的信息，而会觉得没有自然的过度和衔接。在介绍了环保和降低使用成本等优势以后，作者把话题引到了首批无人驾驶汽车的试用上，
commercially available，almost certainly，technologyas well as liability and maintenance issues，这些词是属于此处的主要信息词，提示下面举措的原因，命题人没有在此处命题，而是避开，命制了一个所谓猜测词义题目。来看试题：
49.What does the underlined word ＂fielded＂ in Paragraph 4 probably mean?
A. Employed.
B. Replaced.
C. Shared.
D. Reduced.
根据field所在原文语境，提示，鉴于一些考量首先要把无人驾驶技术应用于叫车服务领域。field在此处取其名词“领域”的动词含义“应用于某一领域”，在此，也就是把车辆服务划分了，可能有：公共交通，私人汽车，叫车服务等等。所以在理解此词的时候需要理解原语境的微妙提示，而不是简单来随意根据主观判断下结论，尽管结论可能也不是太离谱，至少我查了很多词典，没有查到field的英英解释为employ。细节不做分析。继续下一段，
Policymakers should start thinking now about how to make sure the appearance of driverless vehicles doesn't extend the worst aspects of the car-controlled transportation system we have today. The coming technological advancement presents a chance for cities and states to develop transportation systems designed to move more people, and more affordably. The car of the future is coming. We just have to plan for it.
最后一段，我们看它的情感态度，一个对未来的期待和展望，是建立在对现有一些问题和技术的解决和确认的基础上的，也就是说，作者的观点态度中规中矩，但最后一句还是表达了对未来无人驾驶汽车的正面期待。结尾段，对整个上文信息做了概括总结，综合了上文信息点。看最后一题：
50.What is the author's attitude to the future of self-driving cars?
A. Doubtful.
B. Positive.
C. Disapproving.
D. Sympathetic.
答案是B。这个不多说，假如发散开来还有很多内容能够阐述。
总结一下：
本题目选自主流外刊，时间比较新，话题比较新。命题人对文本进行了一定量的改动删减，个人认为已经影响了准确和地道信息的传递，这是不太看好的地方。文本语言和结构没有特殊难点，试题命制也没有深度思维理解的题目，所以考虑试题安排难度，应该不是难题范畴。解读本文本相当于外刊解读的一个过程了。所以说高考题目文本精良，和外刊解读和运用分割开来不是一个真命题。我记得16年北京好像也是D篇，也是命题人做了一些删减改编，而使得整个行文不达意，试题缺少信息支持。这是一个不可忽视的命题问题。
没有时间和精力做更精细的分析。
下面是试题原文：
Preparing Cities for Robot Cars
The possibility of self-driving robot cars has often seemed like a futurist's dream, years away from materializing in the real world. Well, the future is apparently now. The California Department of Motor Vehicles began giving permits in April for companies to test truly self-driving cars on public roads. The state also cleared the way for companies to sell or rent out self-driving cars, and for companies to operate driverless taxi services. California, it should be noted, isn't leading the way here. Companies have been testing their vehicles in cities across the country. It's hard to predict when driverless cars will be everywhere on our roads. But however long it takes, the technology has the potential to change our transportation systems and our cities, for better or for worse, depending on how the transformation is regulated.
While much of the debate so far has been focused on the safety of driverless cars(and rightfully so), policymakers also should be talking about how self-driving vehicles can help reduce traffic jams, cut emissions(排放) and offer more convenient, affordable mobility options. The arrival of driverless vehicles is a chance to make sure that those vehicles are environmentally friendly and more shared.
Do we want to copy — or even worsen — the traffic of today with driverless cars? Imagine a future where most adults own individual self-driving vehicles.

Preparing Cities for Robot Cars
为自动驾驶汽车做准备的城市
The possibility of self-driving robot cars has often seemed like a futurist's dream,years away from materializing in the read world. Well, the future is apparently now. The California Department of Motor Vehicles began giving permits in April for companies to test truly self-driving cars on public roads. The state also cleared the way for companies to sell or rent out self-driving cars, and for companies to operate driverless taxi services. California, it should be noted, isn't leading the way here. Companies have been testing their vehicles in cities across the country. It's hard to predict when driverless cars will be everywhere on our roads. But however long it takes, the technology has the potential to change our transportation systems and our cities, for better or for worse, depending on how the transformation is regulated.
自动驾驶汽车的可能性通常看起来是未来主义者的梦想，距离真实世界里的实现还要好几年。然而，未来显然就是现在。今年四月，加州机动车管理局开始发放许可证，允许各公司在公共道路上测试真正的自动驾驶汽车。州政府还为企业出售或出租自动驾驶汽车以及运营无人驾驶出租车服务扫清了障碍。值得注意的是，加州在这方面并没有走在最裂段前沿。各公司一直在全国各大城市测试他们的汽车。很难预测公路上何时能遍布无人驾驶汽车。但是无论需要多长时间，这项技术都有可能肆衫誉改变我们的交通和城市，至于是好还是坏，就取决于如何管理这种转变。
While much of the debate so far has been focused on the safety of driverless cars(and rightfully so), policymakers also should be talking about how self-driving vehicles can help reduce traffic jams, cut emissions and offer more convenient, affordable mobility options. The arrival of driverless vehicles is a chance to make sure that those vehicles are environmentally friendly and more shared.
虽然到目前为止大部分的讨论都集中在无人驾驶汽车的安全性上（确有塌虚道理），决策制定者也应该讨论自动驾驶汽车如何帮助减少交通阻塞、减少排放，提供更便捷、更实惠的灵活性选择。无人驾驶汽车的到来是一个机会，可以确保那些汽车对环境友好，有更多的共享机会。
Do we want to copy-or even worsen-the traffic of today with driverless cars? Imagine a future where most adults own individual self-driving vehicles. They tolerate long, slow journeys to and from work on packed highways because they can work, entertain themselves or sleep on the ride, which encourages urban spread. They take their driverless car to an appointment and set the empty vehicle to circle the building to avoid paying for parking. Instead of walking a few blocks to pick up a child or the dry cleaning, they send the self-driving minibus. The convenience even leads fewer people to take public transport—an unwelcome side effect researchers have already found in ride-hailing services.
我们想通过无人驾驶汽车复制甚至恶化现在的交通状况吗？想象一下，未来大多数成年人都拥有自己的自动驾驶汽车。这样他们就能够忍受在拥挤的高速公路上上下班的漫长而缓慢的旅程了，因为他们可以在路上工作、娱乐或睡觉，这也会鼓励城市的扩张。他们把无人驾驶汽车带到约会的地点之后，就让空车绕着大楼行驶，以此避免付停车费。他们不再步行几个街区去接孩子或者去干洗店，只要让无人驾驶的迷你巴士去就可以了。这种便利甚至会让越来越少的人乘坐公共交通——研究人员已经在叫车服务中发现了这种糟糕的负面效果。
A study from the University of California at Davis suggested that replacing petrol-powered private cars worldwide with electric, self-driving and shared systems could reduce carbon emissions from transportation 80% and cut the cost of transportation infrastructure and operations 40% by 2050. Fewer emissions and cheaper travel sound pretty appealing. The first commercially available driverless cars will almost certainly be fielded by ride-hailing services, considering the cost of self-driving technology as well as liability and maintenance issues. But driveless car ownership could increase as the prices drop and more people become comfortable with the technology.
加州大学戴维斯分校的一项研究表明，在全球范围内，用电动、自动驾驶和共享取代了汽油动力的私家车，至2050年，可以减少交通运输中80%的碳排放，并降低40%的交通基础设施和运营成本。更少的排放和更便宜的驾驶听起来很有吸引力。几乎可以肯定的是，考虑到无人驾驶技术的成本以及责任和维护问题，第一批商业化的无人驾驶汽车将在叫车服务行业诞生。不过随着价格的下降以及越来越多的人熟练掌握这项技术，无人驾驶汽车的拥有率可能会提高。
Policymakers should start thinking now about how to make sure the appearance of driverless
vehicles doesn't extend the worst aspects of the car-controlled transportation system we have today. The coming technological advancement present a chance for cities and states to develop transportation systems designed to move more people, and more affordably. The car of the future is coming. We just have to plan for it.
决策制定者应当开始考虑，如何确保无人驾驶汽车的出现不会加剧我们现今这个被汽车主导的交通的弊端。即将到来的技术进步为城市和各州提供了发展交通的机会，这些交通旨在承载更多的人、更加便宜。未来汽车就要来了，我们只需要做好准备。
Plastic-Eating Worms
吃塑料的蠕虫
Humans produce more than 300 million tons of plastic every year. Almost half of that winds up in landfills， and up to 12 million tons pollute the oceans. So far there is no effective way to get rid of it, but a new study suggests an answer may lie in the stomachs of some hungry worms.
人类每年生产超过3亿吨塑料，其中几乎一半被作为垃圾填埋， 多达1200万吨污染海洋。目前还没有有效的方法来消除它，但一项新的研究表明慎核瞎宽空，答案可能在于一些饥饿蠕虫的胃。
Researchers in Spain and England recently found that the worms of the greater wax moth can break down polyethylene, which accounts for 40% of plastics. The team left 100 wax worms on a commercial polyethylene shopping bag for 12 hours, and the worms consumed and broke down about 92 milligrams, or almost 3% of it. To confirm that the worms' chewing alone was not responsible for the polyethylene breakdown, the researchers made some worms into paste and applied it to plastic films. 14 hours later the films had lost 13% of their mass--apparently broken down by enzymes from the worms' stomachs. Their findings were published in Current Biology in 2017.
西班牙和英国的研究人员最近发现，大蜡螟的蠕虫可以分解聚乙烯，聚乙烯占塑料的40%。研究小组将100只蜡虫蠕虫放在一个商用聚乙烯购物袋中12小时，这些蠕虫消耗并分解了约92毫克，约占总量的3%。为了证实蠕虫的咀嚼并不是聚乙烯分解的原因，研究人员将一些蠕虫制成糊状物并将其放置于塑料薄膜。14小时后，这些胶片失去了13%的质量——显然被蠕虫胃里的酶分解了。他们的发现发表在2017年的《当代生物学》上。
Federica Bertocchini, co-author of the study, says the worms' ability to break down their everyday food-beeswax--also allows them to break down plastic. "Wax is a complex mixture, but the basic bond in polyethylene, the carbon-carbon bond, is there as well, "she explains. "The wax worm evolved a method or system to break this bond. "
这项研究氏岁的合著者费德丽卡·贝尔托基尼说，蠕虫分解日常食物——蜂蜡的能力，也可以让它们分解塑料。“蜡是一种复杂的混合物，但聚乙烯中的基本键——碳碳键——也存在，”她解释道，“蜡虫进化出一种方法或来破坏这种键。”
Jennifer Debruyn, a microbiologist at the University of Tennessee, who was not involved in the study, says it is not surprising that such worms can break down polyethylene. But compared with previous studies, she finds the speed of breaking down in this one exciting. The next step, DeBruyn says, will be to identify the cause of the breakdown. Is it an enzyme produced by the worm itself or by its gut microbes?
田纳西大学的微生物学家詹妮弗·德布鲁恩没有参与这项研究，她说，这种蠕虫可以破坏聚乙烯，这并不奇怪。但与之前的研究相比，她发现这次研究的分解速度令人兴奋。德布鲁恩说，下一步将是确定分解原因。这种酶是由蠕虫自身产生还是肠道微生物产生？
Bertocchini agrees and hopes her team’s findings might one day help employ the enzyme to break down plastics in landfills. But she expects using the chemical in some kind of industrial process-not simply "millions of worms thrown on top of the plastic.”
贝尔托基尼对此表示同意，并希望她的研究小组的发现有朝一日能利用这种酶在垃圾填埋场分解塑料。但她希望在某种工业过程中使用这种化学物质，而不仅仅是将“数百万只蠕虫扔在塑料上”。
