They were, by far, the largest and most distant objects that scientists had ever detected: a strip of enormous cosmic clouds some 15 billion light-years from earth. 迄今为止,科学家所发现的最大、最遥远的物体是:离地球大约150亿光年的一块狭长的巨大宇宙云系。71) But even moreimportant, it was the farthest that scientists had been able to look into the past, for whatthey were seeing were the patterns and structures that existed 15 billion years ago.更为重要的是,这是科学家们能够观测到的最遥远的过去的景象,因为他们看到的是150亿年前宇宙云的形状和结构。That was just about the moment that the universe was born.那大约就是宇宙形成的时候。What the researchers found was at once both amazing and expected: the US National Aeronautics and Space Administration’s Cosmic Background Explorer satellite -- Cobe -- had discovered landmark evidence that the universe did in fact begin with the primeval explosion that has become known as the Big Bang (the theory that the universe originated in an explosion from a single mass of energy).研究人员所发现的宇宙云既令人惊讶,又在人们的意料之中:美国国家航空航天局的Cobe号(宇宙背景探测器)已经发现了划时代的证据,表明宇宙确实起源于最早的一次爆炸,人们称之为"大爆炸"(此理论认为宇宙起源于一大块能量的爆炸)。72) The existence of the giant clouds was virtually required for the Big Bang, first put forward in the 1920s, to maintain its reign as the dominant explanation of the cosmos. 巨大的宇宙云的存在,实际上是20年代首创的大爆炸论得以保持其宇宙起源论的主导地位不可缺少的。According to the theory, the universe burst into being as a submicroscopic, unimaginably dense knot of pure energy that flew outward in all directions, emitting radiation as it went, condensing into particles and then into atoms of gas. Over billions of years, the gas was compressed by gravity into galaxies, stars, plants and eventually, even humans.按照这一理论,宇宙形成于一团亚微观的、密度相当大的纯能量团,它在向四面八方发散的过程中放出辐射线,浓缩成粒子,然后形成气体原子。数十亿年来,这种气体在引力的压缩下形成星系、恒星、植物,甚至最终产生人类。Cobe is designed to see just the biggest structures, but astronomers would like to see much smaller hot spots as well, the seeds of local objects like clusters and superclusters of galaxies.设计Cobe卫星就是要观察这些最大的物体结构,但宇航员还想看到更小的热点,即,像星系中的星团和超星团这样一些局部物体的粒子。They shouldn’t have long to wait.看来他们不必等待很长时间。73) Astrophysicists working with ground-based detectors atthe South Pole and balloon-borne instruments are closing in on such structures, and may reporttheir findings soon.天体物理学家使用南极陆基探测器和球载仪器,正在越来越近地观测这些云系,也许不久会报告他们的观测结果。74) If the small hot spots look as expected, that will be a triumph for yet another scientific idea, a refinement of the Big Bang called the inflationary universe theory.假如这些小热点看上去同预计的一致,那就意味着又一种科学论说的胜利,这种论说即更完美的大爆炸论,亦称宇宙膨胀说。Inflation says that very early on, the universe expanded in size by more than a trillion trillion trillion trillionfold in much less than a second, propelled by a sort of antigravity. 膨胀说认为,很久以前,在一种反引力的驱动下,宇宙的体积在不到一秒钟内膨胀了无数倍。75) Odd though it sounds, cosmic inflation is a scientifically plausible consequence of some respected ideas in elementary particle physics, and many astrophysicists have been convinced for the better part of a decade that it is true.宇宙膨胀说虽然听似奇特,但是它是基本粒子物理学中一些公认的理论产生的在科学上看来似乎可信的结论。许多天体物理学家近十年来一直确信这一论说是正确的。
原文+译文:Science, in practice, depends far less on the experiments it prepares than on the preparedness of the minds of the men who watch the experiments.实际上,科学的进步依赖于做实验,但更依赖于实验的观察者(即做实验的人)有所准备的头脑。Sir Isaac Newton supposedly discovered gravity through the fall of an apple.据说艾萨克·牛顿爵士是从苹果落地现象中发现了万有引力。Apples had been falling in many places for centuries and thousands of people had seen them fall. But Newton for years had been curious about the cause of the orbital motion of the moon and planets.多少个世纪以来,许多地方一直都有苹果落到地面,成千上万的人也都看过苹果落地。但多年来只有牛顿一直对月球和行星沿轨道运行的起因感到好奇。What kept them in place? Why didn’t they fall out of the sky? The fact that the apple fell down toward the earth and not up into the tree answered the question he had been asking himself about those larger fruits of the heavens, the moon and the planets.是什么使它们保持在现在的位置?它们为什么不从天上掉下来?苹果向下落到地面而不向上飞到树上,这一事实回答了他长期以来一直对天空中更大的“果实”——月球和行星所存有的疑问。How many men would have considered the possibility of an apple falling up into the tree?多少人会考虑过苹果向上飞到树上的可能性呢?Newton did because he was not trying to predict anything. He was just wondering. His mind was ready for the unpredictable. Unpredictability is part of the essential nature of research.牛顿这样做了,因为他不想对任何事情进行预测。他只是怀有好奇心。他的头脑在准备思考不可预测的事。不可预测性是科学研究的一个基本特征。If you don’t have unpredictable things, you don’t have research. Scientists tend to forget this when writing their cut and dried reports for the technical journals, but history is filled with examples of it.如果没有不可预测现象的产生就无所谓科学研究了。科学家们在为学术刊物撰写呆板的例行报告时往往会忘记这一点,而历史上这样的例子却比比皆是。In talking to some scientists, particularly younger ones, you might gather the impression that they find the “scientific method” a substitute for imaginative thought.在和一些科学家,特别是年轻科学家交谈时,你可能会有这样一种印象:他们认为“科学方法”可以代替创造性思维。I’ve attended research conferences where a scientist has been asked what he thinks about the advisability of continuing a certain experiment.我出席过一些科研会议,会上有人问一位科学家继续某项实验是否是明智之举。The scientist has frowned, looked at the graphs, and said “the data are still inconclusive.”那位科学家皱了皱眉,又看了看图表,然后说:“数据还是不够确定。”“We know that,” the men from the budget office have said, “but what do you think? Is it worthwhile going on? What do you think we might expect?” The scientist has been shocked at having even been asked to speculate.预算部门的人说:“这点我们知道,但你的意见如何?你觉得值得做下去吗?你觉得我们可以期待什么呢?”这位科学家感到很震惊,他没有料到人们会让他做出预测。What this amounts to, of course, is that the scientist has become the victim of his own writings.当然,这几乎等于说:这位科学家成了自己所写报告的受害者。He has put forward unquestioned claims so consistently that he not only believes them himself, but has convinced instrial and business management that they are true.他所提出的种种论断是如此不容置疑、如此一致,以至于不仅他自己相信了,而且也说服了工商界的管理者相信其正确性。If experiments are planned and carried out according to plan as faithfully as the reports in the science journals indicate, then it is perfectly logical for management to expect research to proce results measurable in dollars and cents.假如科学实验像科学杂志报告显示的那样完全按事先的计划去规划和实施,那么,对管理层来说,期待研究能够产生可用美元、美分衡量的结果是完全合理的。It is entirely reasonable for auditors to believe that scientists who know exactly where they are going and how they will get there should not be distracted by the necessity of keeping one eye on the cash register while the other eye is on the microscope.审计人员也完全有理由相信,确切知道自己的目标并知道如何实现这一目标的科学家们根本没必要分心:用一只眼盯着现金计数器的同时,用另一只眼睛盯着显微镜。Nor, if regularity and conformity to a standard pattern are as desirable to the scientist as the writing of his papers would appear to reflect, is management to be blamed for discriminating against the “odd balls” among researchers in favor of more conventional thinkers who “work well with the team.”如果像他们的论文所反映的那样,科学家渴望规律性和与某种标准模式的一致性,那么管理人员歧视研究人员中的“标新立异者”,而赞赏“善于合作”的具有传统思维模式的人,也就是无可指摘的。试题:51.

原文+翻译:Few creations of big technology capture the imagination like giant dams.在重大技术所创造的东西中很少能像大型水坝这样激起人们想象力的。Perhaps it is humankind’s long suffering at the mercy of flood and drought that makes the idea of forcing the waters to do our bidding so fascinating.可能正是因为人类长期遭受旱涝灾害的摆布才使得人们治理江河、供我驱策的理想如此令人痴迷。But to be fascinated is also, sometimes, to be blind. Several giant dam projects threaten to do more harm than good.但让人着迷有时也就使人盲目。有几个巨型大坝项目就有弊大于利的危险。The lesson from dams is that big is not always beautiful.建造大坝的教训是:大的未必总是美的。It doesn’t help that building a big, powerful dam has become a symbol of achievement for nations and people striving to assert themselves.但这个教训也无法阻止修建高大雄伟的大坝已成为那些力争得到自我肯定的国家和人民的伟大成就的象征。Egypt’s leadership in the Arab world was cemented by the Aswan High Dam.埃及由于建造了阿斯旺大坝而巩固了在阿拉伯世界的领导地位。Turkey’s bid for First World status includes the giant Ataturk Dam.土耳其在力图跻身第一世界的努力中也包括修建阿塔特克大坝。But big dams tend not to work as intended.但大坝不会像预期的那样产生效果。The Aswan Dam, for example, stopped the Nile flooding but deprived Egypt of the fertile silt that floods left -- all in return for a giant reservoir of disease which is now so full of silt that it barely generates electricity.以阿斯旺大坝为例,它阻止了尼罗河洪水泛滥,但也使埃及失去了洪水冲击过后留下的肥沃土壤,换回来的却是一个疾病滋生的水库。现在这个水库积满了淤泥,几乎不能发电了。And yet, the myth of controlling the waters persists.不过,控制水的神话还在继续。This week, in the heart of civilized Europe, Slovaks and Hungarians stopped just short of sending in the troops in their contention over a dam on the Danube.本周,在文明的欧洲腹地,斯洛伐克人和匈牙利人就为了多瑙河上的一处水坝引起争端,差点动用了军队。The huge complex will probably have all the usual problems of big dams. But Slovakia is bidding for independence from the Czechs, and now needs a dam to prove itself.这个大型工程可能会出现大坝所有的常见问题。但斯洛伐克正在要求脱离捷克而独立,现在它们需要建一个大坝来证明自己的实力。Meanwhile, in India, the World Bank has given the go-ahead to the even more wrong-headed Narmada Dam.与此同时,世界银行已经贷款给印度来建造问题更多的纳尔马达大坝。And the bank has done this even though its advisors say the dam will cause hardship for the powerless and environmental destruction. The benefits are for the powerful, but they are far from guaranteed.尽管世界银行的顾问指出,该大坝将给平民带来苦难,而且会破坏那里的环境,但世界银行依然一意孤行。大坝只会给有权有势者带来利益,而且这种利益也远远得不到保障。Proper, scientific study of the impacts of dams and of the cost and benefits of controlling water can help to resolve these conflicts.对于水坝的影响作用、水坝控制水流的成本和收益进行恰当而科学的研究能够有助于解决这些冲突。Hydroelectric power and flood control and irrigation are possible without building monster dams.水力发电,治理洪水以及灌溉即使不建大型水坝也是可能的。But when you are dealing with myths, it is hard to be either proper, or scientific. It is time that the world learned the lessons of Aswan. You don’t need a dam to be saved.但当你相信神话时就很难做到合理或科学。现在是世界吸取阿斯旺大坝教训的时候了。我们未必要通过大坝来拯救自己。试题:51. The third sentence of Paragraph 1 implies that.[A] people would be happy if they shut their eyes to reality[B] the blind could be happier than the sighted[C] over-excited people tend to neglect vital things[D] fascination makes people lose their eyesight52. In Paragraph 5, “the powerless” probably refers to.[A] areas short of electricity[B] dams without power stations[C] poor countries around India[D] common people in the Narmada Dam area53. What is the myth concerning giant dams?[A] They bring in more fertile soil.[B] They help defend the country.[C] They strengthen international ties.[D] They have universal control of the waters.54. What the author tries to suggest may best be interpreted as.[A] “It’s no use crying over spilt milk”[B] “More haste, less speed”[C] “Look before you leap”[D] “He who laughs last laughs best”答案:C D D C
原文+翻译:Science has long had an uneasy relationship with other aspects of culture. Think of Gallileo’s 17th-century trial for his rebelling belief before the Catholic Church or poet William Blake’s harsh remarks against the mechanistic worldview of Isaac Newton. 科学与文化其他方面的关系一直都很紧张。想想看,17世纪伽利略为他叛逆性的信仰而遭受天主教会的审判,还有诗人威廉·布莱克对艾萨克·牛顿的机械论世界观所发表的尖锐批判。The schismbetween science and the humanities has, if anything, deepened in this century.本世纪,(自然)科学与人文科学之间如果说有什么的话,那就是分裂更深了。Until recently, the scientific community was so powerful that it could afford to ignore its critics -- but no longer.以前,科学界如此之强大以至于可以对批评者置之不理--但现在不同了。As funding for science has declined, scientists have attacked “anti-science” in several books, notably Higher Superstition, by Paul R. Gross, a biologist at the University of Virginia, and Norman Levitt, a mathematician at Rutgers University; and The Demon-Haunted World, by Carl Sagan of Cornell University.由于科研基金减少,科学家开始在几本著作中抨击"反科学"势力,特别是弗吉尼亚大学生物学家保罗·R·格罗斯和拉特格斯大学的数学家诺曼·莱维特合著的《高级迷信》及康奈尔大学的卡尔·萨根著的《鬼怪出没的世界》。Defenders of science have also voiced their concerns at meetings such as “The Flight from Science and Reason,” held in New York City in 1995, and “Science in the Age of (Mis) information,” which assembled last June near Buffalo.科学的捍卫者们也在一些会议上表示了他们的担忧。比如,1995年在纽约举行的"远离科学和理性"会议,以及去年6月在布法罗附近召开的"(伪)信息时代的科学"会议。Anti-science clearly means different things to different people. Gross and Levitt find fault primarily with sociologists, philosophers and other academics who have questioned science’s objectivity. Sagan is more concerned with those who believe in ghosts, creationism and other phenomena that contradict the scientific worldview.显然,反科学对不同的人有不同的含义。格罗斯和莱维特主要挑那些质疑科学客观性的社会学家、哲学家和其他学者的毛病。而萨根则更关注那些相信鬼怪、上帝造物论和其他违背科学世界观的现象的人。A survey of news stories in 1996 reveals that the anti-science tag has been attached to many other groups as well, from authorities who advocated the elimination of the last remaining stocks of smallpox virus to Republicans who advocated decreased funding for basic research.1996年对新闻报道的调查表明,反科学的标签也贴在了许多其他群体上,从提倡消灭最后残存的天花病毒库的官方人士到倡议削减基础研究基金的共和党人。Few would dispute that the term applies to the Unabomber, whose manifesto, published in 1995, scorns science and longs for return to a pre-technological utopia. But surely that does not mean environmentalists concerned about uncontrolled instrial growth are anti-science, as an essay in US News & World Report last May seemed to suggest.将该词用在在美国制造一连串类似炸弹爆炸事件的人身上,也不会引起多大争议,他在1995年公开发表蔑视科学、渴望回到前技术时代的理想社会的声明。当然,这并不意味着,对不加控制的工业发展表示担忧的环保主义者也是反科学的,而去年5月份刊登在《美国新闻和世界报导》的一篇文章却似乎暗示是这么回事。The environmentalists, inevitably, respond to such critics. The true enemies of science, argues Paul Ehrlich of Stanford University, a pioneer of environmental studies, are those who question the evidence supporting global warming, the depletion of the ozone layer and other consequences of instrial growth.环保主义者必定会对这些批评做出反应。作为环境研究的先驱者,斯坦福大学的保罗·埃利希认为,科学的真正的敌人是那些对全球变暖、臭氧层稀薄和其他由于工业增长带来的后果的证据提出质疑的人。Indeed, some observers fear that the anti-science epithet is in danger of becoming meaningless. “The term ‘anti-science’ can lump together too many, quite different things,” notes Harvard University philosopher Gerald Holton in his 1993 work Science and Anti-Science.“They have in common only one thing that they tend to annoy or threaten those who regard themselves as more enlightened.”的确,一些观察者担心反科学这个称号面临失去意义的危险。"'反科学'一词可以涵盖很多截然不同的东西",哈佛大学的哲学家杰拉尔德·霍尔顿在其1993年的著作《科学与反科学》中写道:"它们惟一的共同之处就是会激怒或威胁那些自以为比别人更有见识的人。"试题:51. The word “schism” (Line 4, Paragraph 1) in the context probably means.[A] confrontation[B] dissatisfaction[C] separation[D] contempt52. Paragraphs 2 and 3 are written to.[A] discuss the cause of the decline of science’s power[B] show the author’s sympathy with scientists[C] explain the way in which science develops[D] exemplify the division of science and the humanities53. Which of the following is true according to the passage?[A] Environmentalists were blamed for anti-science in an essay.[B] Politicians are not subject to the labeling of anti-science.[C] The “more enlightened” tend to tag others as anti-science.[D] Tagging environmentalists as “anti-science” is justifiable.54. The author’s attitude toward the issue of “science vs. anti-science” is.[A] impartial[B] subjective[C] biased[D] puzzling答案:C D A A
原文+翻译:Scattered around the globe are more than 100 small regions of isolated volcanic activity known to geologists as hot spots. 地球上散落分布着一百多个互不相连的小火山活动区,被地质学家称为热点。Unlike most of the world’s volcanoes, they are not always found at the boundaries of the great drifting plates that make up the earth’s surface; on the contrary, many of them lie deep in the interior of a plate.和世界上大多数火山不同的是,它们并不总是在构成地球表面的巨大漂流板块之间的边界上被发现;相反,许多热点深藏于板块内部。Most of the hot spots move only slowly, and in some cases the movement of the plates past them has left trails of dead volcanoes. The hot spots and their volcanic trails are milestones that mark the passage of the plates.大多数热点只缓慢地移动,有时,经过这些热点的板块运动留下了死火山的痕迹。热点及其火山痕迹是标志板块迁移的里程碑。That the plates are moving is now beyond dispute.板块漂移这一理论现在是毋庸置疑的。Africa and South America, for example, are moving away from each other as new material is injected into the sea floor between them.以非洲和南美洲为例,由于有新的物质注入二者之间的海底,两大洲正在彼此分离。The complementary coastlines and certain geological features that seem to span the ocean are reminders of where the two continents were once joined.但互相吻合的海岸线和某些似乎跨越海洋的地质特征会使人想到这两个大陆曾经是连在一起的。The relative motion of the plates carrying these continents has been constructed in detail,携带这些大陆的板块的相对运动已经能够被详细地阐述出来,but the motion of one plate with respect to another cannot readily be translated into motion with respect to the earth’s interior.但一个板块相对另一板块的运动还不能轻易地解释为相对于地球内部的运动。It is not possible to determine whether both continents are moving in opposite directions or whether one continent is stationary and the other is drifting away from it. Hot spots, anchored in the deeper layers of the earth, provide the measuring instruments needed to resolve the question. From an analysis of the hot-spot population it appears that the African plate is stationary and that it has not moved ring the past 30 million years.人们不能确定两个大陆是在朝相反的方向运动,还是一个大陆停止不动而另一个从它身边漂移开去。位于地球更深层的热点提供了解决该问题所需要的测量仪器。从热点地区的人口情况分析来看,非洲板块似乎是静止不动的,在过去3000万年里都没有移动过。The significance of hot spots is not confined to their role as a frame of reference.热点的重要性不仅限于作为参照体系这一作用。It now appears that they also have an important influence on the geophysical processes that propel the plates across the globe.现在看来,它们还对推动板块在地球表面漂移这一地球物理过程有重要影响。When a continental plate come to rest over a hot spot, the material rising from deeper layers creates a broad dome. As the dome grows, it develops deep fissures (cracks);当大陆板块漂移到热点上方,来自地球深层的物质便形成了巨大的圆顶状隆起物。随着这个圆顶的增长,板块出现深深的裂缝。in at least a few cases the continent may break entirely along some of these fissures, so that the hot spot initiates the formation of a new ocean. Thus just as earlier theories have explained the mobility of the continents, so hot spots may explain their mutability (inconstancy).至少有几次,大陆可能会沿着其中的一些裂缝完全裂开了,因此这个热点就引发了一个新的海洋的形成。这样,正像早期的理论解释了大陆的移动性一样,热点理论或许能解释大陆板块的不稳定性。试题:51. The author believes that.[A] the motion of the plates corresponds to that of the earth’s interior[B] the geological theory about drifting plates has been proved to be true[C] the hot spots and the plates move slowly in opposite directions[D] the movement of hot spots proves the continents are moving apart52. That Africa and South America were once joined can be deced from the fact that.[A] the two continents are still moving in opposite directions[B] they have been found to share certain geological features[C] the African plate has been stable for 30 million years[D] over 100 hot spots are scattered all around the globe53. The hot spot theory may prove useful in explaining. [A] the structure of the African plates[B] the revival of dead volcanoes[C] the mobility of the continents[D] the formation of new oceans54. The passage is mainly about.[A] the features of volcanic activities[B] the importance of the theory about drifting plates[C] the significance of hot spots in geophysical studies[D] the process of the formation of volcanoes答案:BBDC
原文+译文:When a Scottish research team startled the world by revealing 3 months ago that it had cloned an alt sheep, President Clinton moved swiftly. 三个月前,当一个苏格兰研究小组宣布他们克隆了一只成年绵羊时,世界为之震惊,克林顿总统迅速做出反应。Declaring that he was opposed to using this unusual animal husbandry technique to clone humans, he ordered that federal funds not be used for such an experiment -- although no one had proposed to do so -- and asked an independent panel of experts chaired by Princeton President Harold Shapiro to report back to the White House in 90 days with recommendations for a national policy on human cloning.他宣称反对利用这种非同寻常的畜牧业技术去克隆人,并下令禁止联邦资金用于此类实验——尽管还没有人提议要那样做——并要求一个由普林斯顿大学校长哈罗德·夏皮罗为首的独立专家小组,在九十天内拿出有关克隆人的国家政策的建议,向白宫汇报。That group -- the National Bioethics Advisory Commission (NBAC) -- has been working feverishly to put its wisdom on paper, and at a meeting on 17 May, members agreed on a near-final draft of their recommendations.这个名为“全国生物伦理道德顾问委员会”(NBAC)的小组一直在非常积极地工作,集思广益,并诉诸笔端;在5月17日的一次会议上,委员们就接近定稿的意见书取得了一致意见。NBAC will ask that Clinton’s 90-day ban on federal funds for human cloning be extended indefinitely, and possibly that it be made law.NBAC将要求克林顿总统禁止联邦资金用于克隆人的九十天禁令无限期地延长,并且还可能要求将之立法。But NBAC members are planning to word the recommendation narrowly to avoid new restrictions on research that involves the cloning of human DNA or cells -- routine in molecular biology.但是,NBAC成员们正计划在建议的措辞上更为严谨,以避免给克隆人体DNA或细胞等研究带来更多的限制——(这属于)分子生物研究中的常规课题。The panel has not yet reached agreement on a crucial question, however, whether to recommend legislation that would make it a crime for private funding to be used for human cloning.然而,该小组尚未在一个关键问题上达成一致,即是否建议立法机关将私人资金用于克隆人的行为法定为犯罪。In a draft preface to the recommendations, discussed at the 17 May meeting, Shapiro suggested that the panel had found a broad consensus that it would be “morally unacceptable to attempt to create a human child by alt nuclear cloning.”在5月17日会议上讨论的建议序言草案中,夏皮罗表示,专家组已取得广泛的共识,认为“试图利用成人细胞核去克隆婴儿将是违背道德伦理的”。Shapiro explained ring the meeting that the moral doubt stems mainly from fears about the risk to the health of the child. The panel then informally accepted several general conclusions, although some details have not been settled.夏皮罗解释说在与会期间,道德上的怀疑主要源于对婴儿健康的担忧。随后,该小组非正式地接受了几项概括性的结论,尽管有些细节尚无定论。NBAC plans to call for a continued ban on federal government funding for any attempt to clone body cell nuclei to create a child. Because current federal law already forbids the use of federal funds to create embryos (the earliest stage of human offspring before birth) for research or to knowingly endanger an embryo’s life, NBAC will remain silent on embryo research.NBAC计划呼吁继续禁止为任何企图利用人体细胞核去制造婴孩的做法提供联邦政府基金资助。因为现行的联邦法律已经禁止联邦基金用于制造研究用的胚胎(人类后代出生前的最早阶段)或有意识地危及胚胎的生命,所以NBAC在胚胎研究这一问题上将保持沉默。NBAC members also indicated that they will appeal to privately funded researchers and clinics not to try to clone humans by body cell nuclear transfer. NBAC的成员明确表示,他们将呼吁受私人基金资助的研究人员和诊所不要尝试通过人体细胞核转移来克隆人。But they were divided on whether to go further by calling for a federal law that would impose a complete ban on human cloning. Shapiro and most members favored an appeal for such legislation, but in a phone interview, he said this issue was still “up in the air.”但他们在是否进一步要求联邦立法强令完全禁止克隆人这一问题上存在分歧。夏皮罗和大多数委员赞成将此立法,但在电话采访中,他透露这一议题仍“悬而未决”。试题:51. We can learn from the first paragraph that.[A] federal funds have been used in a project to clone humans[B] the White House responded strongly to the news of cloning[C] NBAC was authorized to control the misuse of cloning technique[D] the White House has got the panel’s recommendations on cloning52. The panel agreed on all of the following except that.[A] the ban on federal funds for human cloning should be made a law[B] the cloning of human DNA is not to be put under more control[C] it is criminal to use private funding for human cloning[D] it would be against ethical values to clone a human being53. NBAC will leave the issue of embryo research undiscussed because_.[A] embryo research is just a current development of cloning[B] the health of the child is not the main concern of embryo research[C] an embryo’s life will not be endangered in embryo research[D] the issue is explicitly stated and settled in the law54. It can be inferred from the last paragraph that.[A] some NBAC members hesitate to ban human cloning completely[B] a law banning human cloning is to be passed in no time[C] privately funded researchers will respond positively to NBAC’s appeal[D] the issue of human cloning will soon be settled答案:B C D A
本文强调了要为大学生提供更多课程方面的信息,从而使他们在对各门不同学科进行钻研之后,选择符合自己兴趣和能力的学科。It would be interesting to discover how many young people go to university without any clear idea of what they are going to do afterwards.发现有多少上大学的年轻人对将来要做什么没有任何明确的想法,将是一件有趣的事情。(21) If one considers the enormous variety of courses offered, it is not hard to see how difficult it is for a student to select the course most suited to his interests and abilities.(21)如果想一想那些为学生设置的门类繁多的课程,我们就不难发现,对一个学生来说,要选一门符合他的兴趣和能力的课程是多么困难。(22) If a student goes to university to acquire a broader perspective of life, to enlarge his ideas and to learn to think for himself, he will undoubtedly benefit.(22)如果一个学生进大学是为了想获得一个对生活前景更广泛的认识,为了扩大思想境界和学会独立思考,那么毫无疑问,进大学对他是有好处的。(23) Schools often have too restricting an atmosphere, with its time tables and disciplines, to allow him much time for independent assessment of the work he is asked to do.(23)学校由于受课程表和纪律的约束,气氛往往令人感到过于拘束,使学生没有充分时间对规定要他做的事情有独立的见解。(24) Most students would, I believe, profit by a year of such exploration of different academic studies, especially those “all rounders” with no particular interest.(24)我认为大多数学生,尤其是那些没有偏重某一门课程的“全面发展的学生”,经过一年左右的时间对各门不同学科的钻研,将会从中获益。They should have longer time to decide in what subject they want to take their degrees, so that in later life, they do not look back and say, “I should like to have been an archaeologist.他们应该有更长的时间来决定想拿什么学科的学位,以便在以后的岁月里回顾过去时不会说,“我希望自己是一名考古学家。If I hadn’t taken a degree in Modern Languages, I shouldn’t have ended up as an interpreter, but it’s too late now. I couldn’t go back and begin all over again.”如果我没有获得现代语言的学位,就不会成为一名翻译,但现在为时已晚。我不能回头再重新来过了。(25) There is, of course, another side to the question of how to make the best use of one’s time at university.(25)当然,关于一个人如何最充分地利用上大学的时间,还有另外一个方面。(26) This is the case of the student who excels in a particular branch of learning.(26)某一学科中出类拔萃的学生就属于这种情况。(27) He is immediately accepted by the University of his choice, and spends his three or four years becoming a specialist, emerging with a first-class Honour Degree and very little knowledge of what the rest of the world is all about.(27)他一毕业马上就被一所他自己选中的大学所接受,再花三、四年时间成为一名专家。结果他以优异的成绩取得荣誉学位,但对外界的一切却几乎一无所知。(28) It therefore becomes more and more important that, if students are not to waste their opportunities, there will have to be much more detailed information about courses and more advice.(28)因此,如果要学生好好利用他们上大学的机会,就应该为他们提供大量关于课程方面更为详尽的信息和更多的的建议。这个问题显得越来越重要了。Only in this way can we be sure that we are not to have, on the one hand, a band of specialists ignorant of anything outside of their own subject,只有这样,我们才能确保:一方面,我们不会有一帮对自己学科以外的事情完全无知的专家,and on the other hand, an ever increasing number of graates qualified in subjects for which there is little or no demand in the working world.另一方面,我们不会有越来越多的毕业生具备这个工作世界很少或没有需求的学科的知识。
The American economic system is organized around a basically private-enterprise, market-oriented economy in which consumers largely determine what shall be proced by spending their money in the marketplace for those goods and services that they want most. 美国的经济体制是在基本上由私营企业组成并以市场为导向的经济基础上建立起来的。在这个经济体制里,需要生产什么主要是由消费者在市场上花钱购买他们最需要的商品和服务决定的。Private businessmen, striving to make profits, proce these goods and services in competition with other businessmen; and the profit motive, operating under competitive pressures, largely determines how these goods and services are proced.为了获取利润,私有企业主之间互相竞争,来生产这些产品和提供这些服务。在竞争的压力下运作,追求利润的动机很大程度上决定了生产商品和提供服务的方式。Thus, in the American economic system it is the demand of indivial consumers, coupled with the desire of businessmen to maximize profits and the desire of indivials to maximize their incomes, that together determine what shall be proced and how resources are used to proce it.因此,在美国的经济体制中,消费者个人的需求、商人对获取最大利润的追求以及消费者渴望最大化自己的收入,所有这些共同决定了应该生产什么和如何利用资源去生产这些产品。An important factor in a market-oriented economy is the mechanism by which consumer demands can be expressed and responded to by procers.在以市场为导向的经济中的一个重要因素是反映消费者需求以及生产者对消费者需求作出反应的机制。In the American economy, this mechanism is provided by a price system, a process in which prices rise and fall in response to relative demands of consumers and supplies offered by seller-procers.在美国经济中,这一机制是由价格体制提供,在价格体系中,价格随消费者的相对需求和出售者及生产者的供应情况而上下浮动。If the proct is in short supply relative to the demand, the price will be bid up and some consumers will be eliminated from the market.如果产品相对供不应求,价格就会抬升,从而使一些消费者从市场上消失。If, on the other hand, procing more of a commodity results in recing its cost, this will tend to increase the supply offered by seller-procers, which in turn will lower the price and permit more consumers to buy the proct.另一方面,如果商品的大量生产导致成本的降低,这会促使销售商和生产商供给的增加,从而反过来导致价格下降,致使更多的消费者购买产品。Thus, price is the regulating mechanism in the American economic system.因此,价格是美国经济体制中的调节机制。The important factor in a private-enterprise economy is that indivials are allowed to own proctive resources (private property), and they are permitted to hire labor, gain control over natural resources, and proce goods and services for sale at a profit.私有企业经济的一个重要因素是允许个人拥有生产资料(私有财产),允许他们雇用劳动力,控制自然资源,以及生产产品、提供服务以获取利润。In the American economy, the concept of private property embraces not only the ownership of proctive resources but also certain rights, including the right to determine the price of a proct or to make a free contract with another private indivial.在美国经济中,私人财产的概念不仅仅包含对生产资料的所有权,还包含某些其他权利,其中包括确定产品的价格或与另一私营者签订自由合同。11.[答案]D[解析]本题考核的知识点是:句题题。先定位到第一段末句。解题的关键是看对maximize的理解。原文所在句“coupled with the desire of businessmen to maximize profits and the desire of indivials to maximize their incomes”将生产者和消费者的愿望对照来说。句中的两个maximize平衡并列,作用、意义完全相同。因此知道maximize在第一处的意义即可知道第二处之意。众所周知,商人总是想用最少的投入取得最大的利润,这就是maximize的意义。由此可知,消费者希望使一定的收入取得最大限度的效益,即用现有收入买到更多更好的商品。而[D]选项恰是此意。[A]和[B]选项未在原文提及。[C]选项反映的是劳资双方的关系,而不是生产者与消费者之间的关系。12.[解析] 本题考核的知识点是:事实细节题。[D]选项就是该段第二句“prices rise and fall in response to relative demands of consumers and supplies offered by seller-procers”的概括,为正确答案。[A]选项在这两句中并未涉及。注意文中第一句的mechanism意为“机制”,而该选项中的mechanized意为“机械化”,二者含义不同。误选[B]选项的考生是对该段首句的语法成分分析错误。它是一个省略句,补全后应该是“An important factor in a market-oriented economy is the mechanism by which consumer demands can be expressed and (by which consumer demands can be) responded to by procers”。由此可知,消费者通过这一机制表达他们的需求,而生产者则通过这一机制对他们的需求作出反应。[B]选项理解成consumer demands can be expressed…by procers。[C]选项与第二句“供求关系决定价格”不符,也应该排除。此题亦可通过经济常识解答。注意:干扰选项经常使用原文中出现的词语或类似的结构伪造,所以对那些出现了原词的选项一定要仔细辨认真伪。13.[答案]A[解析] 本题考核的知识点是:段落主旨题。题干要求考生回答私营企业经济的特点,即第三段的主题。该段只有两句。第一句强调的是私营企业最重要的因素是个人拥有生产资料(私人财产)、允许个人雇用劳动力和控制自然资源。第二句是指私人财产的概念还包含某些其他权利,如:产品价格的决定权或与其他私有个体的自由签约权。尤其第二句的not only… but also…更表明了此段主旨。[A]选项是对上述内容的概括,为正确答案。而[B]、[C]和[D]选项虽然都在第三段述及,但是都是[A]选项下的具体内容,缺乏概括性,不应该入选。命题意图要求考生区分段落细节与段落中心是局部与整体的关系。14.[答案]C[解析] 本题考核的知识点是:文章主旨题。解此题需要了解文章各段的主旨。第一段论述美国经济体制的构成;第二段介绍市场经济的运行方式;第三段介绍私营经济的特点。后两段是对第一段的进一步论述。由此可见,美国经济体制的构成和运作是本文论述的中心。[C]选项正反映了这一主题。[A]、[B]和[D]选项都在文中有所涉及,但都是具体细节,比较片面,应该排除。此题还可以通过直接对选项进行比较排除来解题。[A]、[B]和[D]都在文中述及,分属于三个独立的、不同的概念。其中任意一个可代表其他两个,而[C]选项概括性强,可以包括[A]、[B]和[D],故[C]为正确答案。
大家好,咱们来看一篇阅读,这篇阅读是1996年考研英语试卷一的第五篇阅读,介绍了一本关于批评创世论的著作,原文如下,并把原文内的中文翻译也一并给出,方便理解。原文:Rumor has it that more than 20 books on creationism/evolution are in the publisher’s pipelines. A few have already appeared.有传言说,有20多本关于创世论与进化论之争的书即将出版,其中有几本已经面世。The goal of all will be to try to explain to a confused and often unenlightened citizenry that there are not two equally valid scientific theories for the origin and evolution of universe and life.出版所有这些书的目的是试图告诉那些迷惑不解且常常头脑不开化的普通百姓:就宇宙和生命的起源与发展问题而言,不可能存在两种同样成立的科学理论。Cosmology, geology, and biology have provided a consistent, unified, and constantly improving account of what happened.对于所发生的一切,宇宙学、地质学、生物学已经提供了一贯的、统一的并且是在不断完善的解释。“Scientific” creationism, which is being pushed by some for “equal time” in the classrooms whenever the scientific accounts of evolution are given, is based on religion, not science.而“科学”创世论——当课堂上讲授进化论时,有些人就想争抢“相同的课时”来解释它——是基于宗教,而非科学的。Virtually all scientists and the majority of non-fundamentalist religious leaders have come to regard “scientific” creationism as bad science and bad religion.实际上,所有科学家和大多数非原教旨主义宗教领袖们都已将“科学”创世论看作是拙劣的科学和拙劣的宗教。The first four chapters of Kitcher’s book give a very brief introction to evolution.金切尔这本书的前四章简要地介绍了进化论。At appropriate places, he introces the criticisms of the creationists and provides answers.在适当的地方,作者引入了对创世论的非难并提供了回答。In the last three chapters, he takes off his gloves and gives the creationists a good beating.在书的后三章,他毫不客气地对创世论者进行了猛烈抨击。He describes their programmes and tactics, and, for those unfamiliar with the ways of creationists, the extent of their deception and distortion may come as an unpleasant surprise.他揭露了这些人的行动计划和骗人手段,对那些不了解创世论者惯用手法的人来说,其欺骗和歪曲事实的程度会令人感到气愤和震惊。When their basic motivation is religious, one might have expected more Christian behavior.由于他们的基本动机是宗教,人们原本还期待他们会做出更具基督精神的行为。Kitcher is a philosopher, and this may account, in part, for the clarity and effectiveness of his arguments.金切尔是位哲学家,这也许能部分说明他的立论为何明确而有说服力。The non-specialist will be able to obtain at least a notion of the sorts of data and argument that support evolutionary theory.非专业人士起码可以从中了解支持进化论的各种数据和观点。The final chapter on the creationists will be extremely clear to all.关于创世论者的最后一章对每个人来说都阐述得极为清楚。On the st jacket of this fine book, Stephen Jay Gould says: “This book stands for reason itself.”这部优秀作品的护封上,斯蒂芬·杰·古尔德这样写道:“本书代表了理性”。And so it does -- and all would be well were reason the only judge in the creationism/evolution debate.的确如此——如果理性是创世论和进化论之争的唯一评判标准,一切问题就已解决了。试题:51. “Creationism” in the passage refers to.[A] evolution in its true sense as to the origin of the universe[B] a notion of the creation of religion[C] the scientific explanation of the earth formation[D] the deceptive theory about the origin of the universe52. Kitcher’s book is intended to.[A] recommend the views of the evolutionists[B] expose the true features of creationists[C] curse bitterly at this opponents[D] launch a surprise attack on creationists53.
