大学英语阅读理解无人车
① 2018高考英语阅读理解北京卷D篇浅析
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，属于普通的说事文吧，依然是侧重introce 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 — or even worsen — the traffic of today with driverless cars? Imagine a future where most alts own indivial 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 rece 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. Reced.
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 rece 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 — or even worsen — the traffic of today with driverless cars? Imagine a future where most alts own indivial 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.

2019年6月大学英语四级阅读理解训练：迹运前宇宙
A scientist once said: “I have concluded that the earth is being visited by intelligently controlled vehicles from outer space.”
If we take this as a reasonable explanation for UFOs (unidentified flying objects), questions immediately come up.
姿清“Why don’t they get in touch with us, then? Why don’t they land right on the White House lawn and declare themselves?” people asked.
悄租In reply, scientists say that, while this may be what we want, it may not necessarily be what they want.
“The most likely explanation, it seems to me,” said Dr. Mead, “is that they are simply watching what we are up to -- that responsible society outside our solar system is keeping an eye on us to see that we don’t set in motion a chain reaction that might have unexpected effects for outside our solar system.”
Opinions from other scientists might go like this: “Why should they want to get in touch with us? We may feel we’re more important than we really are! They may want to observe us only and not interfere with the development of our civilization. They may not care if we see them but they also may not care to say ‘hello’.”
①Some scientists have also suggested that Earth is a kind of zoo or wildlife reserve. ②Just as we set aside wilderness areas and wildlife reserves to allow animals and growing things to develop naturally while we observe them, so perhaps Earth was set aside ages ago for the same purpose.
①Are we being observed by intelligent beings from other civilizations in the universe? ②Are they watching our progress in space travel? ③Do we live in a gigantic “zoo” observed by our “keepers,” but having no communication with them?
①Never before in our history have we had to confront ideas like these. ②The simple fact is that we, who have always regarded ourselves as supreme in the universe, may not be so. ③Now we have to recognize that, among the stars in the heavens, there may very well be worlds inhabited by beings who are to us as we are to ants.
一、词汇
1.conclude v. 作结论，推断
2.vehicle n. 交通工具
3.be up to sth= be doing sth正在做
4.keep an eye on sb监视某人
5.set in motion使某物运转
6.reserve n. 贮存，预备舍
7.set aside 保留
8.supreme a. 最高的
9.inhabit v. 居住于，占据
二、长难句
1. The most likely explanation, it seems to me,” said Dr. Mead, “is that they are simply watching what we are up to -- that responsible society outside our solar system is keeping an eye on us to see that we don’t set in motion a chain reaction that might have unexpected effects for outside our solar system.
该句的宾语由直接引语构成。该直接引语的主干为The most likely explanation is that …，破折号的部分对that引导的表语从句进行解释说明。该部分的主干为responsible society … is keeping an eye on us，不定式结构to see that …做目的状语。其中第一个that引导的从句做see的宾语，第二个that引导的从句做后置定语，修饰先行词chain reaction。
翻译：米德博士称“在我看来，最可能的解释是他们只不过是看看我们在做什么——我们太阳系之外有责任心的社会正留意着我们，以确保我们不会触发某种连锁反应，从而给太阳系之外的星系造成意想不到的影响。”
2. Just as we set aside wilderness areas and wildlife reserves to allow animals and growing things to develop naturally while we observe them, so perhaps Earth was set aside ages ago for the same purpose.
该句为主从复合句，just as引导方式状语从句，其中还嵌套了while引导的时间状语从句。主句部分的主干为perhaps Earth was set aside。
翻译：就像我们划出野生动物活动区和保护区以便我们可以在自然状态观察动植物的生长情况一样，或许地球就是很早以前为达到相同的目的而被划出的保护区。
3. Now we have to recognize that, among the stars in the heavens, there may very well be worlds inhabited by beings who are to us as we are to ants.
该句的主干为we have to recognize that …，that引导的从句做宾语。该从句的主干为there may very well be worlds，过去分词短语inhabited by beings …做后置定语，修饰名词worlds，who引导的定语从句也做后置定语，修饰beings。
翻译：现在我们必须认识到在茫茫星海中，也许就有这样的星体，那上面居住的生物看待我们就如同我们看待蚂蚁一样。
三、文章结构分析
本文是一篇探讨外星生物是否存的时文。
第一至三段：通过一位科学家的话引出争论的焦点：外星生物是否存在?
第四至八段：罗列了科学家们对此问题而产生的四种猜测—不愿同人类接触、在暗中留意人类的行动、只出于观察目的而不想同人类接触、地球是外星人划立的“动物”保护区。
第九段：总结全文，肯定外星生物的存在，并提醒人们宇宙中存在着更强大生物的可能性。
四、试题具体分析
11. People who ask the question “Why don’t they get in touch with us... and declare themselves?” think that ________.11. 提出“那么他们为什么不和我们联系呢?为什么他们不正好降落到白宫的草坪上然后自我介绍一下呢?”这些问题的人认为________.
[A] there are no such things as UFOs[A] 不明飞行物这种东西是不存在的
[B] UFOs are visitors from solar system[B] 不明飞行物是来自太阳系的探访者
[C] there’s no reason for UFOs sooner or later[C] 对于不明飞行物的说法迟早会理屈词穷的
[D] we are bound to see UFOs sooner or later[D] 人类迟早会看见不明飞行物的
[分析]本题考查的知识点是：推理引申。
根据第一、二段可知，题干中的问题是“如果将来自外太空的智能飞船正在造访地球作为对不明飞行物的合理解释”就会出现的问题。第四到七段引用科学家的话对这一问题给予了回复：对为什么人类同外星人之间没有联系进行了推测。可见，问这些问题的人并不相信外星生物或不明飞行物是存在的，而科学家的推测却在证明它们可能是存在的。故[A]选项正确。
[B]选项是根据UFOs和solar system编造的干扰项，且[B]选项本身表达亦不正确。文中指出如果外星人是存在的，那他们一定存在于太阳系之外的某个星系之中。[C]选项错在no reasons。文章第四到七段给出针对这些问题的解答，所以并非是理屈词穷。[D]选项反向干扰，从上面的分析可知提出问题的人是不相信UFOs是存在的，所以他们也不会认为迟早会见到不明飞行物。
12. According to Dr. Mead, the attitude of beings from outer space toward us is one of ________.12.米德博士认为来自外太空的生物对人类的看法会是_______。
[A] unfriendliness[A] 不友善的
[B] suspicion[B] 猜疑的
[C] superiority[C] 盛气凌人的
[D] hostility[D] 敌意的
[分析]本题考查的知识点是：推理引申。
根据题中人物关键词Dr. Mead定位到文章第五段。针对一些人提出的外星人为何不同人类接触的问题，米德博士认为最可能的解释就是他们只是负责留意我们，确保我们的行动不会触发能够危害到他们的连锁反应。由此可知，米德博士的观点是外星人对人类的态度应该是猜疑的，故[B]选项正确。
[A]、[C]选项都是其他猜测认为来外星生物会对人类所持的态度。[D]选项从文中无从推知。
13. The tone of the writer is that of ________.13. 作者的语气是________。
[A] doubt[A] 怀疑的
[B] warning[B] 警告的
[C] indifference[C] 冷漠的
[D] criticism[D] 批判的
[分析]本题考查的知识点是：作者态度。
文章第八段是作者观点的阐述。第八段第二句指出人类从未有过外星生物是否存在的想法正是人类自身的盲目优越感所致。作者认为也许正是这种盲目自大，使我们否定了外星生物的存在，但是外星生物一定是存在于茫茫宇宙的某个星体上，他们看待我们就如同我们看待蚂蚁一般。可见本文作者所持的是批判的态度，故[D]选项正确。
[A]选项反向干扰。第八段第三句话明确指出，我们必须认识到茫茫星海中也许真的有外星生物的存在。从文中无法得出作者对否定外星人存在的人所给的警示之语，故排除[B]选项。第八段中always, supreme, have to, who are to us as we are to ants等表明了作者并不是漠然的，故[C]选项错误。
五、全文翻译
一位科学家曾说过“我断定来自外太空的智能飞船正在造访地球。”
如果我们将其作为对不明飞行物的合理解释，那么问题马上就来了。
人们会问：“那么他们为什么不和我们联系呢?为什么他们不正好降落到白宫的草坪上然后自我介绍一下呢?”
对于这些问题，科学家们的回答是：虽然这也许是我们想要的，但这也许并不是他们想要的啊。
米德博士称“在我看来，最可能的解释是他们只不过是看看我们在做什么——我们太阳系之外有责任心的社会正留意着我们，以确保我们不会触发某种连锁反应，从而给太阳系之外的星系造成意想不到的影响。”
其他科学家的观点是这样的：“他们为什么要联系我们?我们也许把自己想的过于重要了!他们也许就是想观察我们而不想介入人类文明的发展。他们也许并不关心我们是否看到了他们，也不关心是否打个招呼。”
还有一些科学家认为，地球就是一个动物园或是野生动物保护区。就像我们划出野生动物活动区和保护区以便我们可以在自然状态观察动植物的生长情况一样，或许地球就是很早以前为达到相同的目的而被划出的保护区。
宇宙中其他文明的智能生物正在观察我们么?他们正留意我们在太空航行上的进展么?我们是生活在一个只能被“饲养员”观察却无法与其沟通的巨型“动物园”里么?
在人类的历史上，我们从未遇到过类似的想法。真相很简单，那就是我们总认为在整个宇宙中我们是至高无上的，可事实也许并非如此。现在我们必须认识到在茫茫星海中，也许就有这样的星体，那上面居住的生物看待我们就如同我们看待蚂蚁一样。
2019年6月大学英语四级阅读理解训练：汽车
①The use of the motor is becoming more and more widespread in the twentieth century; as an increasing number of countries develop both technically and economically, so a larger proportion of the world’s population is able to buy and use a car. ②Possessing a car gives a much greater degree of mobility, enabling the driver to move around freely. ③The owner of a car is no longer forced to rely on public transport and is, therefore, not compelled to work locally. ④He can choose from different jobs and probably changes his work more frequently as he is not restricted to a choice within a small radius. ⑤Travelling to work by car is also more comfortable than having to use public transport; the driver can adjust the heating in winter and the air conditioning in the summer to suit his own needs and preference. ⑥There is no irritation caused by waiting for trains, buses or underground trains, standing in long patient queues, or sitting on windy platforms, for as long as half an hour sometimes. ⑦With the building of good, fast motorways long distances can be covered rapidly and pleasantly. ⑧For the first time in this century also, many people are now able to enjoy their leisure time to the full by making trips to the country or seaside at the weekends, instead of being confined to their immediate neighbourhood. ⑨This feeling of independence, and the freedom to go where you please, is perhaps the greatest advantage of the car.
①When considering the drawbacks, perhaps pollution is of prime importance. ②As more and more cars are proced and used, so the emission from their exhaust-pipes contains an ever larger volume of poisonous gas. ③Some of the contents of this gas, such as lead, not only pollute the atmosphere but cause actual harm to the health of people. ④Many of the minor illnesses of modern instrial society, headaches, tiredness, and stomach upsets are thought to arise from breathing polluted air; doctors’ surgeries are full of people suffering from illnesses caused by pollution. ⑤It is also becoming increasingly difficult to deal with the problem of traffic in towns; most of the important cities of the world suffer from traffic congestion. ⑥In fact any advantage gained in comfort is often cancelled out in city driving by the frustration caused by traffic jams: endless queues of cars crawling one after another through all the main streets. ⑦As an increasing number of traffic regulation schemes are devised, the poor bewildered driver finds himself diverted and forced into one-way systems which cause even greater delays than the traffic jams they are supposed to prevent. ⑧The mounting cost of petrol and the increased license fees and road tax all add to the driver’s worries. ⑨In fact, he must sometimes wonder if the motor car is such a blessing and not just a menace.
一、词汇
1.Mobility n. 可动性,变动性
2.Radius n. 半径
3.Preference n. 偏爱
4.irritation n. 烦恼
5.queue n. 长队
6.cover v. 行走(距离)
7.confine v. 限制
8.prime a. 首要的,最好的
9.bewildered a. 困惑的
10.divert v. 转移
11.blessing n. 祝福
12.menace n. 威胁
二、长难句
As an increasing number of traffic regulation schemes are devised, the poor bewildered driver finds himself diverted and forced into one-way systems which cause even greater delays than the traffic jams they are supposed to prevent.
该句为主从复合句。句首为as引导的时间状语从句，主干为the poor bewildered driver finds himself diverted and forced …，其中包含“find oneself +过去分词”结构，意为“发现自己(处于某状态)”。Which引导的定语从句做后置定语，修饰先行词one-way systems。
翻译：当越来越多的交通管理方案出台时，晕头转向的司机发现可怜的自己被迫转进了一条单行道，这样耽误的时间超过了他们所避免的交通拥堵时间。
三、文章结构分析
文章主要探讨了汽车广泛使用的利弊问题。
第一段：指出了汽车广泛使用的原因并论述汽车给人类带来的好处：灵活、舒适、快捷、自主。
第二段：主要论述了由于汽车的广泛使用给人类带来的困扰：大气污染、健康威胁、交通堵塞、费用负担。
四、试题具体分析
14. More and more people can afford to buy and use cars because ________.14. 越来越多的人能够购买并使用汽车是因为________。
[A] an increasing number of cars are being proced[A] 生产的汽车越来越多
[B] the cost of cars is getting cheaper with the development of technology[B] 随着技术的进步，汽车的成本也越来越低了
[C] lots of countries have become more developed[C] 许多国家都步入了发达国家之列
[D] the use of cars has proved to be more economical[D] 已经证实使用汽车是较经济的
[分析]本题考查的知识点是：因果细节。
文章第一段①句指出，因为越来越多的国家在技术和经济领域都取得了进步，所以世界上大部分人都能购买并使用汽车了。[C]选项正是对此句话的概括，故正确。
[A]选项张冠李戴。将“汽车的尾气管里排出了更多含有有毒物质的废气的原因，即人们生产的汽车越来越多了”，当成是“越来越来人购买并使用汽车的原因”。[B]选项无中生有，是利用原文词汇develop technically和the cost 编造的干扰项。第二段⑧句指出，飙升的油价和日益上涨的驾驶执照费和养路费使驾车人变得更加忧心忡忡。可见，使用汽车并不会为其所有者节省钱，故排除[D]选项。
15. The advantages of having a car are best experienced in the driver’s ________.15. 拥有汽车最大的好处是驾车人能够体验________。
[A] freedom in choosing his job[A] 选择工作的自由
[B] comfort ring the travels[B] 旅行中舒适的感觉
[C] enjoyment of his leisure time[C] 闲暇时光的享受
[D] feeling of self-reliance[D] 自立的感觉
[分析]本题考查的知识点是：具体细节。
第一段末句明确指出，自主的感觉以及去任何想去的地方的那种自由或许是汽车最大的优点了，故[D]选项正确。
[A]、[B]、[C]选项都是文中谈到的拥有汽车的好处，但并非最大优点，故排除。
16. What is considered by the writer as the greatest menace to the people caused by the widespread use of motor cars?16. 作者认为汽车的广泛使用对人们造成的最大威胁是什么?
[A] air pollution[A]空气污染
[B] traffic jams[B]交通堵塞
[C] fatal diseases[C]致命疾病
[D] high cost[D]高额成本
[分析]本题考查的知识点是：具体细节。
文章第二段①句即明确指出，对于汽车使用的最大弊端可能就是汽车造成的污染问题。故[A]选项正确。
[B]、[D]选项虽然都是汽车使用对人们生活和健康的威胁，但并不是最大的威胁，故排除。[C]选项本身即错误。第二段第四句指出，现代工业社会中许多小病都是由于吸入被汽车尾气污染了的空气而引起的。可知，汽车的使用并不会引发致命的疾病。
五、全文翻译
二十世纪，汽车的用途变得越来越广泛了，因为越来越多的国家在技术和经济领域都取得了进步，所以世界上大部分人都能购买并使用汽车了。拥有一辆汽车就相当于具有更大的灵活性，开车的人可以自由活动。有汽车的人不必再依靠公共交通工具，因此也不必在工作所在地居住了。他可以选择不同的工作，也可能更频繁地跳槽，他不必在离家很近的范围内选择工作了。同乘坐公共汽车相比，开车上班也更加舒适些，人们可以按自己的需要和喜好随着季节来调节车内供暖和空调系统。有时人们要花半个小时站在长长的队伍里或坐在当风的站台内等火车、公交或地铁，由这种情况导致的恼怒也会随着汽车的使用而消失。随着宽敞快捷的高速公路的修建，长途旅行变得快捷且愉快了。许多人能够在周末的时候开车去乡村或海边，好好地享受他们的闲暇时光，而不用限制在住家附近的地方活动，这在本世纪也属首次了。自主的感觉以及去任何想去的地方的那种自由或许是汽车最大的优点了。
考虑到不好的方面，汽车造成的污染或许是其最大的缺点。因为人们生产和使用的汽车越来越多，所以汽车的尾气管里会排出更多含有有毒物质的废气。这种气体中一些成分的，例如铅，不仅污染了大气还对人们健康造成了实际伤害。人们认为现代工业社会中许多小病，例如，头痛、疲劳以及胃不适，都是由于吸入污浊的空气而引起的，医生的诊室里面充满了受其累的病患。处理城市里交通问题也变得越来越棘手了，世界上大多数重要城市都饱受交通堵塞之苦。事实上，在城市中驾车而行，从这种舒适中获取的任何好处都被由交通堵塞造成的沮丧感给抵消了：一眼望不到边际的汽车长龙，一辆跟着一辆慢慢爬过每一条主街道。当越来越多的交通管理方案出台时，晕头转向的司机发现可怜的自己被迫转进了一条单行道，这样耽误的时间超过了他们所避免的交通拥堵时间。飙升的油价和日益上涨的驾驶执照费和养路费使驾车人变得更忧心忡忡。事实上，他肯定有时候会想弄清楚汽车真的只会带来幸福而不会对我们造成威胁么。

⑤ 2019年6月大学英语四级阅读理解训练三篇
2019年6月大学英语四级阅配歼读理解培猛冲训练：梦
Of all the components of a good night's sleep, dreams seem to be least within our control. In dreams, a window opens into a world where logic is suspended and dead people speak. A century ago, Freud formulated his revolutionary theory that dreams were the disguised shadows of our unconscious desires and fears; by thelate 1970s, neurologists had switched to thinking of them as just "mental noise"-the random byprocts of the neural repair work that goes on ring sleep. Now researchers suspect that dreams are part of the mind's emotional thermostat, regulating moods while the brain is "off line." And one leading authority says that these intensely powerful mental events can be not only harnessed but actually brought under conscious control, to help us sleep and feel better. "It's your dream," says Rosalind Cartwright, chair of psychologyat Chicago's Medical Center, "if you don't like it, change it."
he link between dreams and emotions shows up among the patients in Cartwright's clinic. Most people seem to have more bad dreams early in the night, progressing toward happier ones before awakening, suggesting that they are working through negative feelings generated ring the day. Because our conscious mind is occupied with daily life we don't always think about the emotional significance of the day's events-until, it appears, we begin to dream.
知脊And this process need not be left to the unconscious. Cartwright believes one can exercise conscious control over recurring bad dreams. As soon as you awaken, identify what is upsetting about the dream. Visualizehow you would like it to end instead; the next time it occurs, try to wake up just enough to control its course. With much practice people can learn to, literally, do it in their sleep.
At the end of the day, there's probably little reason to pay attention to our dreams at all unless they keep us from sleeping or "we wake up in panic," Cartwright says. Terrorism, economic uncertainties and general feelings of insecurity have increased people's anxiety. Those suffering from persistent nightmares should seek help from a therapist. For the rest of us, the brain has its ways of working through bad feelings.Sleep-or rather dream-on it and you'll feel better in the morning.
练习题：
Choose correct answers to the question:
1.By saying that “dreams are part of the mind's emotional thermostat," (Lines 4-5, Para. 1) the researchers mean that _______.
A.we can think logically in the dreams too
B.dreams can be brought under conscious control
C.dreams represent our unconscious desires and fears
D.dreams can help us keep our mood comparatively stable
2.What did Cartwright find in her clinic?
A.Most bad dreams were followed by happier ones.
B.Divorced couples usually have more bad dreams.
C.One’s dreaming process is related to his emotion.
D.People having negative feelings dream more often.
3.Cartwright believed with much practice，we can learn to _____.
A.control what dreams to dream
B.sleep well without any dreams
C.wake up in time to stop the bad dreams
D.identify what is upsetting about the dreams
4.The author points out that a person who has constant bad dreams should ______
A.learn to control his dreams
B.consult a doctor
C.sleep and dream on it
D.get rid of anxiety first
5.The author most probably thinks that controlling dreams is ______.
A.a good practice
B.a new discovery
C.helpful for everyone
D.not essential for everyone
参考答案及解析
1.[D] 词义理解题。在第1段第4句中，逗号后面的regulating moods是对emotional thermostat的功能进行解释说明，因此可以推断出选项D正确。
2.[C] 事实细节题。最具干扰的是选项A，因为其陈述与第2段第2句的陈述有点相似,但是，此长句说的是大多数人上半夜做噩梦，之后都会做好梦，而不是像选项A中所说大多数噩梦之后是好梦。而且，根据本段第1 句，很明显，选项C是这一句的近义替换。
3 [C] 推理判断题。本题考査对代词的理解。在第3段的最后一句中，代词it应指上文说到的控制噩梦，及时醒来等做法，因此只有选项C涉及了其中一个做法。选项A太泛了，选项B和D在文中并无提及。
4.[B] 事实细节题。本题考查根据构词法猜测词义的能力。解题关键是推断最后一段第3句中therapist的意义，在考纲词汇表中，therapy是“治疗”的意思，因此，therapist应该是专门负责某种治疗的医生，由此可见，选项B是对原文seek help from a therapist的近义替换。
5.[D] 观点态度题。根据最后一句可以推断作者认为如无必要，梦还是不要控制的好。做梦会让你早上感觉舒服一些，因此本题应选D。
2019年6月大学英语四级阅读理解训练：机器人跳舞
The dancers stand motionless at their position and the room grows silent. But as the music starts, they began to move, bending, turning and waving their fans gracefully as they perform. a traditional Japanese dance. Yoshihiro Kuroki watches in silence, occasionally making notes. But as the dance ends, he beams with happiness. The performance has been flawless.
There have been many performances of traditional Japanese dances over the centuries, but this one is unique,because it is performed not by human dancers but by robots. And the performance takes place not in a dance studio but in a laboratory of Sony Corp.'s Entertainment Robot Co. in Shinagawa, Japan, where Kuroki isgeneral manager. He is the mastermind behind a series of even more capable humanoid entertainment robots,starting with the Sony Dream Robot, or SDR, in 1997, up to the current QRIO in 2003.
These delightful machines are only 58 cm tall, about the size of a newborn infant, weigh about 7 kg, and move with 38 degrees of freedom, each with its own servomotor(辅助马达).
QRIO's predecessor, the SDR4X, announced in 2002, can walk, dance, sing, speak, recognize faces, and understand continuous speech. Each robot has two charge-coupled-device cameras to detect color and position andcan locate a colored ball, move toward it, and kick it into a goal. It also has contact sensors in severaljoints to avoid pinching real human fingers. Seeing the robot perform, it is difficult to remember that there is no sentience(知觉)behind those glass eyes.
练习题：
Choose correct answers to the question:
1.Which of the following is the most suitable title of this passage?
A.New Entertainment Robots Proced in Japan.
B.QRIO the Robot Dancers.
C.Robots Man's Best Friend.
D.An Extraordinary Performance in Sony's Lab.
2.Yoshihiro Kuroki ______.
A.is excited when the robots are performing a traditional Japanese dance
B.keeps silent because he is a little unsatisfied with the new proct
C.witnesses the creation of a series of entertainment robots
D.is an executive manager of Sony Corp.
3.Which aspect of the robots is NOT mentioned in the passage?
A.The vividness of their motion.
B.Their pleasant appearance.
C.Their smart designing principles.
D.Their communicative ability.
4.The Sony Dream Robot was___
A.the first human-like entertainment robot developed by the Sony Corp
B.as capable as the QRIO of speaking,dancing,singing and walking
C.largest among all the entertainment robot developed by the Sony Corp
D.the first entertainment robot sold at the market by the Sony Corp
5.The robot can locate colored balls by mens of ____
A.a charge-coupled device
B.two cameras
C.two contacts sensors
D.a digital detector
参考答案及解析
1.[A] 主旨大意题。标题需要既全面又突出地概括文章的主题。本文先是描述“舞蹈演员”，然后揭晓这是些“机器人”(第2段第1句)，接着对Sony公司的一些机器人产品进行详细介绍。选项A比较全面地概括了文章内容。选项B、D只是涉及细节，不能全面地概括本文的内容。而C又过于笼统，不具有针对性。
2.[C] 事实细节题。选项C符合第2段最后一句“He is the mastermind behind a series of... robots...”。仔细阅读有关的细节信息会发现,第1段第3句可帮助否定选项A。第1段最后两句可帮助否定选项B。另外，根据第2段倒数第2句可否定选项D。
3.[D] 事实细节题。全文分四段，分别讨论机器人三方面的特点：第1段和第2段描述机器人舞蹈演员栩栩如生的表演，即选项A;第3段描写它们的外表，即选项B;第4段介绍它们巧妙的设计，即选项C;只有选项D是没有提到的，故为答案。
4.[A] 推理判断题。该句中的分词结构“starting with...”表明the Sony Dream Robot是第一个人形娱乐机器人，因此选项A正确。文章在最后一段的第1句提到两种能说话、跳舞的机器人，但没有提到SDR是否和它们一样，由此可否定选项B。在第3段讨论机器人大小的时候也没有提到SDR体型最大，因此选项C不正确。选项D在文中没有讨论到。
5.[B] 事实细节题。该句中“two…cameras to...”的结构表明这两个摄像头可以用于定位，所以选项B正确。选项A在该句中也有提到，但它只是摄像机的工作机制，而不是用于定位的装置。选项C在下一句提到，但与题干提到的定位功能无关。选项D在文中并未提及。
2019年6月大学英语四级阅读理解训练：决定婴儿性别
Henry III didn't know much about biology. He went through six wives back in the 1500s, looking for one whocould bear him a son. Scientists now know that it's the father's sperm, not the mother's egg, which determines whether a baby is a boy or a girl. And last week researchers at the Genetics and IVF Institute, a private fertility(生育能力)center in Virginia, announced a new technique that will allow parents to choose the sex of their baby-to-be, before it has even been conceived. The scientist used a tiny laser detector to measure the DNA in millions of sperm cells as they pass single file through a narrow tube, like cattle being herded through a corral(牲口栏). In a study published last week, "girl sperm," which has more DNA—the genetic material— in each cell, was collected, while "boy sperm" was discarded. And when purified girl sperm was used to impregnate(使受孕)a group of mothers, 15 of 17 resulting babies turned out to be girls.
The researchers say that "sex selection" can also double a mother's chance of having a son and can be usedto avoid genetic diseases that affect only one gender, such as hemophilia(血友病). But some experts, like New York University fertility specialist Dr. Jamie Grifo, worry that sex selection could lead to a kind ofin uteri(子宫)discrimination, especially in cultures where sons are considered superior to daughters. "It's valuing one gender' over another," Grifo says. "I don't think that's something we should be doing." So far, patients at the institute have been asking for both boys and girls, in order to "balance" their families. And some ethics experts say that's fine, as long as parents are just looking for a little gender variety. "If you have three boys, and you want a girl," says University of Texas reproctive-law professor John Robertson, "that's not gender bias at all."
练习题：
Choose correct answers to the question:
1.The DNA in the sperm cells can be measured ______.
A.in the same way how the cattle are herded
B.when they pass through a tube one behind the other
C.after they pass through a laser tube
D.when they are scanned by a laser detector all at a time
2.The gender of the baby is decided by ______.
A.the father's DNA
B.the mother's DNA
C.the father's sperm
D.the mother's egg
3.According to this passage, the practice of "sex selection" ______.
A.can help to prevent all genetic problems
B.is totally unacceptable to ethics experts
C.was already realized five hundred years ago
D.will benefit families with certain inheritable diseases
4.Girl sperm was preferred to boy sperm in the research most probably because____
A.girl sperm contains more genetic material
B.more mother want to have girl babies
C.girl sperm is healthier and more active
D.girl sperm is more easily purified
5.It can be concluded from the passage that author’s toward”sex selection”is____
A.negative
B.positive
C.neutral
D.favorable
参考答案及解析
1.[B] 推理判断题。解答本题的关键在于推断single file的意思。该句把精子通过试管的情形与牛群被赶入牲口圈的情形作对比，结合single一词本身的意思，可以推断single file是“一个接一个”的意思，只有选项B能表达这个意思，由此也可否定选项D。选项A最具干扰性，原句是把精子通过试管的情形比作牛群被赶人牲口圈的情形，而选项A说的是测定精子内DNA的方法与放牧的方法相同，显然选项A只是引用了原文的某些词语，但表达的意思与原文却截然不同。
2.[C] 事实细节题。第1段第3句which引导的非限制性定语从句修饰的是the father's sperm，而不是插入语the mother’s egg,因此选项C正确。
3.[D] 推理判断题。第2段第1句中的genetic暗示有些疾病是遗传的，即如选项D所述。第2段第1句同时表明选项A的说法是不全面的。选项B与第2段最后两句正好相反。第1段前两句说明选项C是错误的。
4.[A] 事实细节题。第1段倒数第2句中的由which引导的定语从句表明选项A的叙述正确。
5.[C] 观点态度题。文章第2段中作者给出了一些反对者和赞成者的观点，但是没有加以评论，可以看出作者的态度是中立的，故选项C正确。
⑥ 2018年高考英语北京卷 - 阅读理解D
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，这项技术都有可能改变我们的交通系统和城市，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 rece 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 -or even worsen-the traffic of today with driverless cars? Imagine a future where most alts own indivial 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工具——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 rece 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、自动驾驶和共享系统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系统的弊端。即将到来的技术进步为城市和各州提供了发展交通系统的机会，这些交通系统旨在承载更多的人、更加便宜。未来汽车就要来了，我们只需要做好准备。
⑦ 2022年高考英语全国乙卷 - 阅读理解C
Can a small group of drones guarantee the safety and reliability of railways and, at the same time, help railway operators save billions of euros each year? That is the very likely future of applying today's "eyes in the sky" technology to making sure that the millions of kilometres of rail tracks and infrastructure worldwide are safe for trains on a 24/7 basis.
一小群无人机扮冲兄可以保证铁路的安全和可靠性，同时帮助铁路运营商每年节省数十亿欧元吗？这就是应用当今“空中之眼”技术确保全世界数百万公里的铁路轨道和基础设施全天候安全的厅袭未来。
Drones are already being used to examine high-tension electrical lines. They could do precisely the same thing to inspect railway lines and other vital aspects of rail infrastructure such as the correct position of railway tracks and switching points. The more regularly they can be inspected, the more railway safety, reliability and on-time performance will be improved. Costs would be cut and operations would be more efficient across the board.
无人机已经被用来检查高压电线。它们可以做同样的事情来检查铁路线路和铁路基础设施的其他重要方面，如铁路轨判虚道和变轨点的正确位置。越是定期检查，铁路的安全性、可靠性和准时性就越高。全面削减成本，提高运营效率。
That includes huge savings in maintenance costs and better protection of railway personnel safety. It is calculated that European railways alone spend approximately 20 billion euros a year on maintenance, including sending maintenance staff, often at night, to inspect and repair the rail infrastructure. That can be dangerous work that could be avoided with drones assisting the crews' efforts.
这可以节省大量维护成本，更好地保护铁路人员安全。据计算，仅欧洲铁路维护每年就要花费约200亿欧元，包括派遣维护人员（通常在夜间）检查和维修铁路基础设施。这是件危险的工作，无人机协助工作人员则可以避免。
By using the latest technologies, drones could also start providing higher-value services for railways, detecting faults in the rail or switches, before they can cause any safety problems. To perform these tasks, drones for rail don't need to be flying overhead. Engineers are now working on a new concept: the rail drones of the future. They will be moving on the track ahead of the train, and programmed to run autonomously. Very small drones with advanced sensors and AI and travelling ahead of the train could guide it like a co-pilot. With their ability to see ahead, they could signal any problem, so that fast-moving trains would be able to react in time.
通过使用最新技术，无人机还可以开始为铁路提供更高价值的服务，在铁路或道岔出现任何安全问题之前检测出故障。为了执行这些任务，铁路无人机不需要在头顶飞行。工程师们现在正在研究一个新概念：未来的轨道无人机。它们将在列车前方的轨道上移动，编制好程序自动运行。配备先进传感器和人工智能的微型无人机可以像副驾驶一样引导列车前行。凭借它们的前瞻能力，它们可以发出任何问题的信号，以便快速行驶的列车能够及时做出反应。

大学英语阅读理解及答案【1】
Swimming is one of those activities that can be learned early in life. Little children can learn to swim as soon as they walk. In fact, you need the same skills in walking as in swimming. However, I believe that five is the best age to learn. By five or six, a child knows fear of water, a very important thing to know. It's wise to be afraid, to recognize true danger. Young ones understand that the water can sometimes be very dangerous.
To really benefit from swimming, every swimmer should learn, as soon as possible, these four basic strokes; butterfly, backstroke, breastroke, and crawl. I feel that one of these-the breaststroke-is different from the others, since some young swimmers use this stroke naturally, without any training.
In swimming there are certain rules every swimmer should follow:
1. Never swim alone! No matter how good you are in the water, don't risk drowning by swimming alone. If you swim by yourself , with no life guards or friends with you, you may get into trouble.
2. Don't go beyond your abilities. Most swimmers know enough not to swim too far from the bank or the beach, Showing off by doing dangerous tricks is no good. Swim safely and you will continue to swim and alive.
3. Don't smoke. Swimming depends on a healthy body; good lungs are part of it.
4. Work at any activity that builds muscles.
9. Little children can learn to swim as soon as _____.【 B 】
A. they can talk
B. they start walking
C. they have no fear of the water
大学英语阅读理解及答案【2】
Americans spend their free time in various ways.
America is a country of sports—of hunting, fishing and swimming, and of team sports like baseball and football. Millions of Americans watch their favorite sports on television. They also like to play in community orchestras(管弦乐队),make their own films or recordings, go camping ,visit museums, attend lectures, travel, garden, read, and join in hundreds of other activities. The people also enjoy building things for their homes, sewing their own clothes, even making their own photographs. They do these things for fun as well as for economy.
But as much as Americans enjoy their free time, the country is at the same time a"self-improvement" country. More than 25 million alts continue their ecation, chiefly by going to school in the evening, ring their own free time, at their own expense. Added to the time spent on personal activities, Americans a1so devote a great amount of their time to the varied needs of their communities. Many hospitals, schools, libraries, museums, parks, community centers, and organizations that assist the poor depend on the many hours citizens devote to these activities, often without any pay. Why do they do it?
There are several answers. The idea of cooperating and sharing responsibility with one another for the benefit of all is as old as the country itself.
When the country was first founded in 1776,it was necessary for the settlers to work together to live. They had crossed dangerous seas and risked all they had in their struggle for political and religious freedom. There remains among many Americans a distrust of central government. People still prefer to do things themselves within their communities, rather than give the government more control.
Sometimes people offer their time because they wish to accomplish something for which no money is paid, to do something that will be of benefit to the entire community. It is true that some people use their leisure because they are truly interested in the work; or they are learning from the experience.
No matter what the reason is, hundreds of thousands of so called leisure hours are put into hard, unpaid work on one or another community need.

大学英语阅读理解及答案【3】
Early one morning, more than a hundred years ago, an American inventor called Elias Howe finally fell asleep. He had been working all night on the design of a
sewing machine but he had run into a very difficult problem: It seemed impossible to get the thread to run smoothly around the needle.
Though he was tired, Howe slept badly. He turned and turned. Then he had a dream. He dreamt that he had been caught by terrible savages whose king wanted to kill him and eat him unless he could build a perfect sewing machine. When he tried to do so, Howe ran into the same problem as before. The thread kept getting caught around the needle.
The king flew into the cage and ordered his soldiers to kill Howe. They came up towards him with their spears raised. But suddenly the inventor noticed something. There was a hole in the tip of each spear. The inventor awoke from the dream,
realizing that he had just found the answer to the problem. Instead of trying to get the thread to run around the needle, he should make it run through a small hole in the center of the needle. This was the simple idea that finally made Howe design and build the first really practised sewing machine.
Elias Howe was not the only one in finding the answer to his problem in this
way.
Thomas Edison, the inventor of the electric light, said his best ideas came into him in dreams. So did the great physicist Albert Einstein. Charlotte Bronte also drew in her dreams in writing Jane Eyre.
To know the value of dreams, you have to understand what happens when you are asleep. Even then, a part of your mind is still working. This unconscious(无意识的), but still active part understands your experiences and goes to work on the problems you have had ring the day. It stores all sorts of information that you may have
forgotten or never have really noticed. It is only when you fall asleep that this part of the brain can send messages to the part you use when you are awake. However, the unconscious part acts in a special way. It uses strange images which the conscious part may not understand at first. This is why dreams are sometimes called “secret messages to ourselves”.

3.Thomas Edison is spoken of because________.【 B 】

大学英语阅读理解及答案【4】
The greatest recent changes have been in the lives of women. During the
twentieth century there was an unusual shortening of the time of a woman’s life spent in caring for children. A woman marrying at the end of the 19th century would
probably have been in her middle twenties, and would be likely to have seven or eight children, of whom four or five lived till they were five years old. By the time the youngest was fifteen, the mother would have been in her early fifties and would
expect to live a further twenty years, ring which custom, chance and health made it unusual for her to get paid work. Today women marry younger and have fewer
children. Usually a woman’s youngest child will be fifteen when she is forty-five and is likely to take paid work until retirement at sixty. Even while she has the care of
children ,her work is lightened by household appliances(家用电器)and convenience foods.
This important change in women’s way of life has only recently begun to have its full effect on women’ s economic position. Even a few years ago most girls left school at the first opportunity and most of them took a full-time job. However, when they married, they usually left work at once and never returned to it. Today the school-leaving age is sixteen, many girls stay at school after that age ,and though
women tend to marry younger ,more married women stay at work at least until shortly before their first child is born. Many more after wads, return to full or part-time work. Such changes have led to a new relationship in marriage, with both husband and wife accepting a greater share of the ties and satisfaction of family life, and with both husband and wife sharing more equally in providing the money and running the home, according to the abilities and interest of each of them.
