2019年6月大学英语四级阅读理解训练：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.
“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.
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 produced 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 industrial 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 produced[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 during 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。
