原文+翻译:科学研究的各个领域相对发展速度各不相同,其中有若干原因。71) Some of these causes are completely reasonable results of social needs. Others arereasonable consequences of particular advances in science being to some extentself-accelerating.在这些原因中,有些纯属社会需求;另一些则是由于科学上某些特定发展在一定程度上自我加速而产生的必然结果。Some, however, are less reasonable processes of different growth in which preconception of the form scientific theory ought to take, by persons in authority, act to alter the growth pattern of different areas.然而,有些产生发展速度差异的原因就不尽合理,仅是因为某些权威人士对科学理论究竟应采取何种形式有先入为主的想法,这些想法改变了不同学科领域的发展模式。This is a new problem probably not yet unavoidable; but it is a frightening trend.这是一个新问题,虽然可以避免,但其趋势却令人担忧。72) This trend began ring the Second World War, when severalgovernments came to the conclusion that the specific demands that a government wants to makeof its scientific establishment cannot generally be foreseen in detail.这种趋势始于第二次世界大战期间,当时一些国家的政府得出结论:政府要向其科研机构提出具体的要求通常是无法详尽预见的。It can be predicted, however, that from time to time, questions will arise which will require specific scientific answers.然而,可以预见的是,往往会出现一些问题,要求有具体科学的解答。It is therefore generally valuable to treat the scientific establishment as a resource or machine to be kept in functional order.因此,把科研机构看作一种资源或一台机器,应维持其良好的运行状态,这种做法通常很有价值。73) This seems mostly effectively done by supportinga certain amount of research not related to immediate goals but of possible consequence in thefuture.给某些与当前目标无关而将来则可能产生影响的科研予以支持,看来能够有效地解决这个问题。This kind of support, like all government support, requires decisions about the appropriate recipients of funds.与所有政府资助项目一样,这种资助需要确定合适的资金接受对象。Decisions based on utility as opposed to lack of utility are straightforward.根据某一项目是否具有效用做出决策直接明了。But a decision among projects none of which has immediate utility is more difficult.但是在若干没有直接效用的项目中,要做出抉择就困难得多。The goal of the supporting agencies is the praisable one of supporting “good” as opposed to “bad” science, but a valid determination is difficult to make.资助机构的目标是支持“好”的学科,而不资助“坏”的学科,这一点值得赞扬,然而要做出正确的抉择却很困难。Generally, the idea of good science tends to become confused with the capacity of the field in question to generate an elegant theory.人们往往将好学科与该学科是否能够提出一套完美的理论混淆起来。74) However, the world is so made that elegant systems are in principle unable to deal with some of the world’s more fascinating and delightful aspects.然而,世界就是如此,完美的体系一般而言是无法解决世上某些更加引人入胜的课题的。75) New forms of thought as well as new subjects for thought must arise in the future as they have in the past, giving rise to new standards of elegance.同过去一样,将来必然出现新的思维方式和新的思维对象,给完美以新的标准。
There are two basic ways to see growth: one as a proct, the other as a process. People have generally viewed personal growth as an external result or proct that can easily be identified and measured. The worker who gets a promotion, the student whose grades improve, the foreigner who learns a new language -- all these are examples of people who have measurable results to show for their efforts.By contrast, the process of personal growth is much more difficult to determine, since by definition it is a journey and not the specific signposts or landmarks along the way. The process is not the road itself, but rather the attitudes and feelings people have, their caution or courage, as they encounter new experiences and unexpected obstacles. In this process, the journey never really ends; there are always new ways to experience the world, new ideas to try,new challenges to accept.In order to grow, to travel new roads, people need to have a willingness to take risks, to confront the unknown, and to accept the possibility that they may “fail” at first. How we see ourselves as we try a new way of being is essential to our ability to grow. Do we perceive ourselves as quick and curious? If so, then we tend to take more chances and to be more open to unfamiliar experiences. Do we think we’re shy and indecisive? Then our sense of timidity can cause us to hesitate, to move slowly, and not to take a step until we know the ground is safe. Do we think we’re slow to adapt to change or that we’re not smart enough to cope with a new challenge? Then we are likely to take a more passive role or not try at all.These feelings of insecurity and self-doubt are both unavoidable and necessary if we are to change and grow. If we do not confront and overcome these internal fears and doubts, if we protect ourselves too much, then we cease to grow. We become trapped inside a shell of our own making.15.[答案]A[解析]本题考核的知识点是:推理引申题。文章第一段谈到,人们对待成长有两种基本看法:将之视为结果和将之视为过程。该段第二句明确指出前者是人们通常持有的看法,即认为成长是一种外在的结果或成果,易于衡量。可以从该段最后作者给出的一系列例子去理解什么是外在结果。此外,最后一句中的“have measurable results to show for their efforts”表明这种观点认为个人成长也是通过努力取得的结果。这样答案就显而易见了。只有[A]选项既是经过努力又是可以衡量的外在结果,故为正确答案。[B]、[C]和[D]选项都属于过程中付出的努力,结果却不可测量,故都不对。命题意图是要求考生熟悉类比题的一种变相出法,即,不直接对文中内容提问,而是要求考生在正确理解文中的例子后,从选项中选出与之类似的情况。解题关键在于能够把握原来例子的实质。16.[答案]C有关视成长为过程的的论述主要集中在第二段。这种观点认为成长是一段旅程,而不是具体的标记。人们应该看重的是成长过程中的态度和情感而非点滴的成功标记。[C]选项就是一种遭遇困难时的态度,也与第二段末句 “new challenges to accept”观点一致,为正确答案。[A]选项是结果,而非过程。[B]选项显然是从结果的角度去看待人的发展。[D]选项仍然是追求有“标志”的成功结果。因此都可以排除。17.[解析] 本题考核的知识点是:词义题。题干中的短语出自第三段第二句中的how we see ourselves as we try a new way of being。该句之后,作者一连提出并列的三个问题,并给予了回答。三个问句及其回答分别是人由于对自身看法的不同而产生的不同处世方法:how we see ourselves是对三个问题的概括,而a new way of being这个关键词则应该涵盖三个回答的内容。[A]选项是简练、全面的概括,为正确答案。being相当于existing,意为:处世生存方式。首先排除[C],它涉及的是问句的内容,[B]和[D]选项虽然都在该段被提及,但是不具有概括性,应该排除。18.[答案]D[解析] 本题考核的知识点是:作者观点题。第三段首句提到,为了成长,人们需要乐于冒险、勇于面对未知事物、接受“失败”。接下来的一系列设问句说明了“快捷、有好奇心、抓住更多的机会、体验不熟悉的事情、对付新挑战”等的重要性,因此[A]、[B]和[C]选项都在文中提到。而第四段首句“这些不安全感和自我怀疑不仅是无法避免的,而且是必要的”充分表明作者对这些态度的肯定。由此可知,[D]选项与作者观点不一致,而且从第四段第二句作者用的两个假设也可看出他对躲避态度的否定,综上所述可以推出[D]选项为正确答案。全文翻译看待成长有两种基本态度:一种视其为结果,一种视其为过程。(佳句①)人们通常视个人成长为容易被识别和衡量的一种外在结果或成果。工人得到升迁、学生成绩提高和外国人学会了一门新的语言——这些都可以表明人们付出努力之后,取得了可测定的成绩。(长难句①)相比之下,测定个人成长的过程却要艰难得多。因为从定义来看,它是一段旅程,而不是沿途特定的路标或标志物。成长过程不是道路本身,而是当遭遇新的情况或未预料到的坎坷时所持的态度和情感,是慎重行事还是勇往直前。(长难句②)在这个过程中,旅行永远不会真正结束;总是有新的方法来感受世界,总会尝试新思想,接受新挑战。(佳句②)为了成长,为了探索新路,人们需要乐意去冒险,去勇敢面对未知事物,去接受他们也许会一开始就“失败”的可能性。(佳句③)当我们尝试一种新的生存方式时,我们如何看待自己对我们的成长能力至关重要。我们认为自己快捷、有好奇心吗?如果是的话,那我们往往会抓住更多的机会,更愿意去体验不熟悉的事情。我们认为自己腼腆、优柔寡断吗?那我们的羞怯感会使我们犹豫不决、行动缓慢,不到万无一失绝不迈步。我们认为自己适应变化很慢且对付新挑战也不够机敏吗?那么我们极可能会处事较被动或者根本放弃尝试。我们若想改变自己、有所成长,这些不安全感和自我怀疑感既无法避免也很有必要。如果我们不去面对并克服这些内心的恐惧和疑惑,如果我们过多地保护自己,那我们就一定会停止成长。我们会陷进自己营造的壳里面。(佳句④)
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。
“Intelligence” at best is an assumptive construct -- the meaning of the word has never been clear. 智力充其量只是一个假设性的概念,因为智力的含义从来就是模糊的。There is more agreement on the kinds of behavior referred to by the term thanthere is on how to interpret or classify them.人们对智力这个词所指的各种表现意见比较一致,而对这些表现的解释或分类则有不同的看法。But it is generally agreed that a person of high intelligence is one who can grasp ideas readily, make distinctions, reason logically, and make use of verbal and mathematical symbols in solving problems.但普遍认为,智力高的人是能指那些够迅速领会思想、区分事物、进行逻辑推理并运用文字和数字符号来解决问题的人。An intelligence test is a rough measure of a child’s capacity for learning, particularly for learning the kinds of things required in school.智力测验只是粗略衡量一个儿童学习的能力,尤其是学习学校所要求的各种知识的能力。It does not measure character, social adjustment, physical enrance, manual skills, or artistic abilities. It is not supposed to -- it was not designed for such purposes.智力测验并不测定人的个性、社会适应能力、身体耐力、手工技能或艺术才能。其设计初衷也并非为了测定这些方面。To criticize it for such failure is roughly comparable to criticizing a thermometer for not measuring wind velocity.批评智力测试不反映上述情况,就犹如批评温度计不测风速一样。The other thing we have to notice is that the assessment of the intelligence of any subject is essentially a comparative affair.我们要注意的另一件事是,对任何测试对象的智力评估都是比较而言的。Now since the assessment of intelligence is a comparative matter we must be sure that the scale with which we are comparing our subjects provides a “valid” or “fair” comparison.既然对智力的评估是比较而言的,那么我们必须确保,在对我们的对象进行比较时,我们所使用的尺度能提供有效的或公平的比较。It is here that some of the difficulties which interest us begin. Any test performed involves at least three factors: the intention to do one’s best, the knowledge required for understanding what you have to do, and the intellectual ability to do it.正是基于这一点,产生了一些让我们关注的问题。进行任何测试至少要包含三个因素:尽力考好的意向,理解考试要求所需要的知识,以及做这件事情所需的智能。The first two must be equalfor all who are being compared, if any comparison in terms of intelligence is to be made.如果从智力方面进行任何比较的话,那么对所有的被比较者来说,前两个因素必须是一样的。In school populations in our culture these assumptions can be made fair and reasonable, and the value of intelligence testing has been proved thoroughly.在我们的文化培养的学生中,上述设想可以公平合理。这就完全证明了智力测试的价值。Its value lies, of course, in its providing a satisfactory basis for prediction.它的价值当然就在它对预测提供了令人满意的依据。No one is in the least interested in the marks a little child gets on his test;没有人会对一个儿童在测试中所取得的分数感兴趣。what we are interested in is whether we can conclude from his mark on the test that the child will do better or worse than other children of his age at tasks which we think require “general intelligence.”我们感兴趣的是,我们能否从他测试的成绩中得出结论:与同龄人相比,这个儿童在完成我们认为需要“一般智力”的任务时,他会做的更好还是更差。On the whole such a conclusion can be drawn with a certain degree of confidence, but only if the child can be assumed to have had the same attitude towards the test as the others with whom he is being compared, and only if he was not punished by lack of relevant information which they possessed.总的来说,得出这种结论是有一定把握的,但前提是必须两个假定成立:这个孩子对测试的态度和与他相比较的孩子对测试的态度相同;他没有因为缺乏别的孩子已掌握的有关知识而被扣分。
It is all very well to blame traffic jams, the cost of petrol and the quick pace of modern life, but manners on the roads are becoming horrible. 我们可以谴责交通阻塞、汽油价格、以及现代生活的快节奏,但马路礼貌确实越来越糟糕。Everybody knows that the nicest men become monsters behind the wheel. It is very well, again, to have a tiger in the tank, but to have one in the driver’s seat is another matter altogether.所有的人都知道:即便脾气最好的人在车里也会变成怪兽。老虎在油箱里还好说,可老虎若坐在驾驶员的位置上就完全是另一回事了。You might tolerate the odd road-hog, the rude and inconsiderate driver, but nowadays the well-mannered motoristis the exception to the rule. Perhaps the situation calls for a “Be Kind to Other Drivers” campaign, otherwise it may get completely out of hand.你也许能够容忍在马路上横冲直闯的司机、粗鲁且不体谅人的司机,但现今文明驾驶的司机却实属罕见。(可能这需要发起一场“对其他司机友善”的运动,否则,情形会完全失控)。第二段:Road politeness is not only good manners, but good sense too. It takes the most cool-headed and good-tempered of drivers to resist the temptation to revenge when subjected to uncivilized behavior.马路文明不仅是一种礼貌行为,还是一种良好的意识。司机需要非常冷静的头脑和好脾气才能在碰到不文明行为时克制住自己不进行报复。On the other hand, a little politeness goes a long way towards relieving the tensions of motoring.另一方面,些许文明行为十分有助于缓解驾车时的紧张情绪。A friendly nod or a wave of acknowledgement in response to an act of politeness helps to create an atmosphere of goodwill and tolerance so necessary in modern traffic conditions.一个友好的颔首、感谢对方礼貌行为的一个轻轻的挥手有助于形成友好宽容的氛围,But such acknowledgements of politeness are all too rare today. Many drivers nowadays don’t even seem able to recognize politeness when they see it.而这在当前的交通条件下是非常必要的。但现在,这种对礼貌表示认可的行为非常罕见。现今很多司机即使见到礼貌行为也似乎视若惘然。第三段:However, misplaced politeness can also be dangerous. Typical examples are the driver who brakes violently to allow a car to emerge from a side street at some hazard to following traffic, when a few seconds later the road would be clear anyway;但是,误用礼貌同样危险。典型的事例为:司机为了让过从边路上突然出现的车而采取急刹车,却对后面的交通造成了危险。(而若不出现这种情况),本来只需几秒钟的等待,道路就会畅通无阻;or the man who waves a child across a zebra crossing into the path of oncoming vehicles that may be unable to stop in time. The same goes for encouraging old ladies to cross the road wherever and whenever they care to.或者,有人会为一个穿过斑马线的孩子让路,示意其进入行车道,但随后驶来的车辆却无法及时停车。同样,鼓励老太太随时随地横穿马路的行为也是如此。It always amazes me that the highways are not covered with the dead bodies of these grannies.我经常感到奇怪:高速公路上居然没有屡屡出现这些老太太被撞死的交通事故。第四段:A veteran driver, whose manners are faultless, told me it would help if motorists learnt to filter correctly into traffic streams one at a time without causing the total blockages that give rise to bad temper.一位行为无可挑剔的老司机曾告诉我:在不引起交通阻塞,从而惹怒其他司机的前提下,司机们学会逐个插入车流有助于缓解交通。Unfortunately, modern motorists can’t even learn to drive, let alone master the subtler aspects of boatmanship.但现代的驾驶员甚至不会学如何驾车,更别说掌握公路驾车技能的微妙之处了。Years ago the experts warned us that the car-ownership explosion would demand a lot more give-and-take from all road users. It is high time for all of us to take this message to heart.多年前专家就曾警告我们:汽车拥有量的突增要求所有马路使用者的互谅互让。现在是我们该把这项警告铭记于心的时候了。14. According to this passage, troubles on the road are primarily caused by.[A] people’s attitude towards the road-hog[B] the rhythm of modern life[C] the behavior of the driver[D] traffic conditions[分析] 本题考核知识点:第一段主旨题。第一段第二句至段末的内容指出:好人一旦驾车也可能成为伤人的妖怪;过分大胆的司机(tiger)会造成很大的麻烦;鉴于文明驾车的司机太少的现状,为了不至于情况完全失控,有必要发起名为“对其他司机好点”的运动。这说明,形成道路问题的主要原因是司机的行为。 另外,本文其余部分全部是围绕“司机如何正确运用礼貌(politeness),以减少道路问题”进行讨论。所以,[C]为正确选项。误选[A]是因为没有正确理解You might tolerate…rule,本句旨在说明:文明驾驶的司机并不常见;而并非说明人们对于鲁莽司机的态度。[B]、 [D]舍本逐末:文章第一段提到现代生活的节奏和交通状况是为了引出道路问题的主要原因──司机的行为。15. The sentence “You might tolerate the odd road-hog... the rule.” (Para. 1) implies that.[A] our society is unjust towards well-mannered motorists[B] rude drivers can be met only occasionally[C] the well-mannered motorist cannot tolerate the road-hog[D] nowadays impolite drivers constitute the majority of motorists[分析] 本题考核知识点:根据上下文理解句意。本句大意:你可以容忍古怪、粗鲁、不体谅人的司机,但现今文明驾驶的司机却实属罕见。exception to the rule 意为“例外”。[D] 是the well-mannered motorist is the exception to the rule的改写,表达相同的意思,所以为正确选项。[B]与事实相反。[A]、[C]文中未提及。16. By “good sense,” the writer means.[A] the driver’s ability to understand and react reasonably[B] the driver’s prompt response to difficult and severe conditions[C] the driver’s tolerance of rude or even savage behavior[D] the driver’s acknowledgement of politeness and regulations[分析] 本题考核知识点:根据上下文理解短语。根据题干关键词good sense锁定第二段第一句。由于该句是段落主题句,所以对它的理解必然基于对本段内容的把握。本段第一句指出:马路文明不仅是good manners,还是good sense。下文开始对good sense进行具体阐述。第二句说明如何对待他人不礼貌的行为:克制住自己不进行报复;第三句到段末说明如何对待他人的礼貌行为:表示理解并做出认可的反应。所以,[A]是这两方面内容的概括。[C]和[D]都只涉及一个方面的内容,不全面,[B]中“困难且严峻的条件”太笼统,“快速反应”在该段也没有提到。17. Experts have long pointed out that in the face of car-ownership explosion,.[A] road users should make more sacrifice[B] drivers should be ready to yield to each other[C] drivers should have more communication among themselves[D] drivers will suffer great loss if they pay no respect to others[分析]:本题考核知识点:细节题。根据题干中出现的关键词Experts,car-ownership explosion锁定全文倒数第二句。对本题进行判断的主要依据来自于对短语give-and-take 的理解。考生根据本合成词的构成很容易猜测出give-and-take 意为:互相让步,互相迁就(make mutual concessions),[B]中的yield to each other即为此意,所以为正确选项。18. In the writer’s opinion,.[A] strict traffic regulations are badly needed[B] drivers should apply road politeness properly[C] rude drivers should be punished[D] drivers should avoid traffic jams[分析] 本题考核知识点:作者观点题。理解作者的观点需要纵观全文。本文第二段说明司机应该礼貌驾驶并对同行的礼貌行为做出合理反应。第三段说明司机误用礼貌(misplaced politeness ) 同样危险。所以,本文是从正反两方面分析了politeness对减少道路问题的作用。properly对于作者的观点最具有概括力,所以[B]为正确选项。本文并没有从利用交通法规减少交通问题方面进行讨论,所以[A]非本文论述内容。本文也没有提及对野蛮司机的惩罚,所以[C]非正确选项。文章只在开头作为马路问题产生原因之一提及traffic jam,而并没有提到司机应该避免交通高峰以减少交通问题,所以[D]非正确选项。
The fact is that the energy crisis, which has suddenly been officially announced, has been with us for a long time now, and will be with us for an even longer time. 事实是,虽然官方突然宣布能源危机的存在,然而长期以来我们一直面临着能源危机,而且这种情况今后将会持续更长的时间。Whether Arab oil flows freely or not, it is clear to everyone that world instry cannot be allowed to depend on so fragile a base.不管阿拉伯的石油能否源源不断地流出,人人都清楚,再也不能让世界工业依赖于如此脆弱的能源基础了。The supply of oil can be shut off unexpectedly at any time, and in anycase, the oil wells will all run dry in thirty years or so at the present rate of use.石油供应可能随时会被突然切断;不管怎样,以目前这种消费速度,只需30年左右,所有的油井都会枯竭。New sources of energy must be found, and this will take time, but it is not likely to result in any situation that will ever restore that sense of cheap and plentiful energy we have had in the times past.必须找到新的能源,这需要时间;而过去我们感觉到的那种能源廉价而充足的情况将不大可能再出现了。For an indefinite period from here on, mankind is going to advance cautiously, and consider itself lucky that it can advance at all.在今后的漫长的时间内,人类将谨慎前进,而且应该对自己能够继续前进感到非常幸运。To make the situation worse, there is as yet no sign that any slowing of the world’s population is in sight. Although the birth-rate has dropped in some nations, including the United States, the population of the world seems sure to pass six billion and perhaps even seven billion as the twenty-first century opens.使目前状况更糟的是,至今尚无迹象表明,世界人口的增长在近期内会减慢。虽然包括美国在内的一些国家的出生率已经下降,但是在21世纪初世界人口似乎肯定会超过60亿,或许甚至超过70亿。The food supply will not increase nearly enough to match this, which means that we are heading into a crisis in the matter of procing and marketing food.食品供应的增加将远远赶不上人口的增长,这就意味着我们在粮食的生产和购销方面已陷入危机。Taking all this into account, what might we reasonably estimate supermarkets to be like in the year 2001?考虑到所有这些因素,我们可以适当地估计一下2001年的超级市场将会是什么样子呢?To begin with, the world food supply is going to become steadily tighter over the next thirty years -- even here in the United States. By 2001, the population of the United States will be at least two hundred fifty million and possibly two hundred seventy million, and the nation will find it difficult to expand food proction to fill the additional mouths.首先,今后的30年内,世界的食品供应日益紧张,甚至美国这里也不例外。到2001年美国人口将至少达到2亿5千万,也可能是2亿7千万。那时,美国将很难扩大食品生产来满足人口增长的需要。This willbe particularly true since energy pinch will make it difficult to continue agriculture in thehigh-energy American fashion that makes it possible to combine few farmers with high yields.这种困境将是确定无疑的,因为能源的匮乏使农业无法以高能消费这种美国耕作方式继续下去了,而按照这种耕作方式可以投入少数农民就获得高产。It seems almost certain that by 2001 the United States will no longer be a great food-exporting nation and that, if necessity forces exports, it will be at the price of belt-tightening at home.几乎可以肯定,到2001年美国将不再是一个食品输出国;如果必须出口的话,那么其代价就是美国国内人民将勒紧裤带。In fact, as food items will tend to decline in quality and decrease in variety, there is very likely to be increasing use of flavouring additives.实际上,由于各种食品往往会质量下降、品种减少,这就非常有可能更多地使用调味添加物。Until such time as mankind hasthe sense to lower its population to the point where the planet can provide a comfortable supportfor all, people will have to accept more “unnatural food”.除非人类终于意识到要把人口减少到这样的程度,使地球能为所有人提供足够的饮食,否则人们将不得不接受更多的“人造食品”。
“I have great confidence that by the end of the decade we’ll know in vast detail how cancer cells arise,” says microbiologist Robert Weinberg, an expert on cancer.“But,” he cautions, “some people have the idea that once one understands the causes, the cure will rapidly follow. Consider Pasteur, he discovered the causes of many kinds of infections, but it was fifty or sixty years before cures were available.”“我有极大的信心相信到这个十年期结束时我们将会详尽地知晓癌细胞的生成原因,”一位癌症专家和微生物学家罗伯特·温伯格说道。“但是,”他告诫说,“有些人认为一旦人们弄清了病因,治疗方法很快就会跟上。例如法国细菌学家巴斯德,他发现了许多传染病的成因,但治疗方法却在五六十年后才问世。”This year, 50 percent of the 910,000 people who suffer from cancer will survive at least five years. In the year 2000, the National Cancer Institute estimates, that figure will be 75 percent. For some skin cancers, the five-year survival rate is as high as 90 percent. But other survival statistics are still discouraging -- 13 percent for lung cancer, and 2 percent for cancer of the pancreas (胰腺).今年,91万癌症患者中有一半将至少再活5年。国家癌症研究所估计,到2000年存活率将升至75%。现在对于一些皮肤癌来说,5年期的存活率高达90%,但其他类型癌症的存活数据却仍令人沮丧——肺癌13%,胰腺癌2%。With as many as 120 varieties in existence, discovering how cancer works is not easy. The researchers made great progress in the early 1970s, when they discovered that oncogenes, which are cancer-causing genes (基因), are inactive in normal cells.癌症种类现有多达120多种,发现其规律实属不易。研究者在70年代取得了很大的进展。当时他们发现致癌基因,即那些可以引起癌症的基因,在正常细胞中是不活动的。Anything from cosmic rays to radiation to diet may activate a dormant oncogene, but how remains unknown. If several oncogenes are driven into action, the cell, unable to turn them off, becomes cancerous.从宇宙射线到辐射到日常饮食,任何东西都有可能激活处于沉寂状态中的致癌基因,但是如何激活不为人所知。如果若干致癌基因被激活,而细胞无力排除,它们就演变成了癌细胞。The exact mechanisms involved are still mysterious, but the likelihood that many cancers are initiated at the level of genes suggests that we will never prevent all cancers. 导致癌变的确切机制仍然是个谜,但是许多癌症始于基因这一可能性表明我们将永远不能预防所有癌症。“Changes are a normal part of the evolutionary process,” says oncologist William Hayward. Environmental factors can never be totally eliminated; as Hayward points out, “We can’t prepare a medicine against cosmic rays.”“变化是进化过程中的一个正常部分,”肿瘤专家威廉·海沃德说道。环境因素永远无法完全消除,正如海沃德所指出的那样:“我们无法准备出一种抗宇宙射线的药。”The prospects for cure, though still distant, are brighter.“First, we need to understand how the normal cell controls itself. Second, we have to determine whether there are a limited number of genes in cells which are always responsible for at least part of the trouble. If we can understand how cancer works, we can counteract its action.”治癌前景虽然遥远,但却越来越明朗了。“首先,我们需要了解正常细胞如何控制其本身。其次,我们必须查明细胞中是否有一定数量的基因总是造成至少部分麻烦的原因。如果我们能弄清癌症的原理,我们就能采取相应的措施。”23.[答案] D[解析] 本题考核的知识点是:作者意图题。本题考查第一段末句在文中的作用:he (指Pasteur)discovered the causes of many kinds of infections, but it was fifty or sixty years before cures were available。这句话说明发现病因并不意味着一定能够很快找到治疗方法。同时结合该段第一句中对即将了解癌细胞成因的肯定态度以及第二句but的转折,可知作者用Pasteur之例对but后人们的态度进行反驳,提醒人们找到治癌症的方法仍然需要一段漫长的时间。由此可知,[D]选项为正确答案。该段中Weinberg只认为人们在近十年内会对癌症的病因有很深的了解,但是这并不意味着会彻底揭开癌症的秘密,因此[A]选项不正确。[B]选项刚好与Pasteur的例子要说明的问题相反。[C]选项是草率结论。Pasteur发现传染病病因后五六十年才找到治疗方法,这并不意味着癌症亦如此。命题意图是要求考生了解文章中例证方法的写作思路。这里是先提出观点,后举例说明。24.[解析] 本题考核的知识点是:推理引申题。本题考查到2000年癌症患者的情况。根据第二段内容,今年(1994)有50%的癌症患者可存活5年。至2000年(6年后),此存活率将升到75%。对于一些皮肤癌患者来说,目前的5年存活率已高达90%。但是其他类型的存活数据却很让人沮丧——肺癌13%、胰腺癌2%。由此可见,存活率的稳步上升是大趋势。一些皮肤癌的存活比率已相当高但是也有些类型的癌症仍难以攻克。因此[D]选项合乎情理。为正确答案。[A]选项不对。文中第三句指出皮肤癌患者目前的存活率已相当高,达到90%,增长余地已很少,不会再有急剧增长。[B]选项若对,则与5年存活率不符。从1994年~2000年已经有6年时间,无法确保这些人仍然在世。[C]选项与文章内容相悖。命题意图要求考生根据原文所给数据和事实信息进行逻辑推理,排除错误选项。25.[答案] B[解析] 本题考核的知识点是:词义题。第三段第二句和第四句oncogenes which are cancer causing genes are inactive in normal cells… If several oncogenes are driven into action, the cell, unable to turn them off, becomes cancerous说明致癌基因在正常细胞中是不活跃的,但是如果被激活,正常细胞无力排除,它们就会转化为癌细胞,造成伤害。由此可见,[B]选项的内容与此相符,为正确答案。[A]选项与第二句的inactive in normal cells不符。该段第四句提到“一旦被激活,健康细胞就根本起不了排斥作用”,因此[C]、[D]选项都不对,它们都忽视了“一旦被激活”这个条件。activate意思是“使活动,起动”。drive into action的意思是“迫使……行动、生效、起作用”。命题意图要求考生准确理解第三段的内容。注意第四句中的条件句的作用是限制事情发生的条件。26.[答案] C解释词语要结合语境和上下文。从第三段第二句和第三句… oncogenes are inactive in normal cells. Anything from cosmic rays to radiation may activate a dormant oncogene…可以分析出致癌基因原本是不活跃的,外在因素激活的只能是“不活跃,静止状态下的”致癌基因。也就是说activate的对象指的仍然应该是前一句中的inactive oncogenes,因此dormant具有与activate相反意义的特点。[C]选项为正确答案。dormant本身词义为“休眠期的、暂停活动的、潜伏的”(in a state of inactivity but awaiting development or activity),这里与inactive同义,没有二次使用是为了避免语言的重复。[A]选项和[B]选项都不含该词义。[D]选项potential的英文含义是existing in possibility, that can or may come into existence or action,即表示可能出现的东西,而oncogene是已经存在之物,故不对。况且potential与同一句中的activate(make… active)的意思也不搭配。
While there are almost as many definitions of history as there are historians, modern practice most closely conforms to one that sees history as the attempt to recreate and explain the significant events of the past.几乎每个历史学家对史学都有自己的界定,但是现代史学家的实践最趋于认为历史学试图重现过去的重大史实并对其做出解释。Caught in the web of its own time and place, each generation of historians determines anew what is significant for it in the past.由于受其所处时间和地点的限制,每一代史学家都要重新判断过去哪些史料对他们具有重要价值。In this search the evidence found is always incomplete and scattered; it is also frequently partial or partisan.在这种探索中,所发现的证据总是不完全的、零散的,而且常常是不全面的或带有派别色彩的。The irony of the historian’s craft is that its practitioners always know that their efforts are but contributions to an unending process.历史研究这个行当的讽刺意味在于,从事研究的人一直知道,他们的努力只不过是为永无止境的过程添砖加瓦而已。Interest in historical methods has arisen less through external challenge to the validity of history as an intellectual discipline and more from internal quarrels among historians themselves.人们之所以关注历史研究的方法论,主要是因为史学界内部意见不一,其次是因为外界并不认为历史是一门学问。While history once revered its affinity to literature and philosophy, the emerging social sciences seemed to afford greater opportunities for asking new questions and providing rewarding approaches to an understanding of the past.尽管历史学一度崇尚它与文学和哲学的相似之处,但新兴的社会科学似乎提供了更多机会,以便人们能够提出新问题,有了解过去的有效途径。Social science methodologies had to be adapted to a discipline governed by the primacy of historical sources rather than the imperatives of the contemporary world.社会科学研究的方法论必须进行改变以适应这样一个学科,其基础是史料,而不是当代社会的需要。During this transfer, traditional historical methods were augmented by additional methodologies designed to interpret the new forms of evidence in the historical study.在这种转变中,历史学家研究历史时,那些解释新史料的新方法充实了传统的历史研究方法。Methodology is a term that remains inherently ambiguous in the historical profession.在历史学界,方法论这个词从来都是模棱两可的。There is no agreement whether methodology refers to the concepts peculiar to historical workin general or to the research techniques appropriate to the various branches of historicalinquiry.所谓方法论是指一般的历史研究中的特有概念,还是指历史探究中各个具体领域适用的研究手段,人们对此意见不一。Historians, especially those so blinded by their research interests that they have been accused of “tunnel method,” frequently fall victim to the “technicist fallacy.”史学家,尤其是那些单纯局限于他们研究兴趣的史学家,被指责为使用“单方向研究法”,他们常常成为“纯技术方法论”的牺牲品。Also common in the natural sciences, the technicist fallacy mistakenly identifies the discipline as a whole with certain parts of its technical implementation.纯技术方法论错误地把整个学科与学科研究的某些操作方法等同起来,这种情况在自然科学领域里也屡见不鲜。It applies equally to traditional historians who view history as only the external and internal criticism of sources, and to social science historians who equate their activity with specific techniques.这种谬误同样存在于历史传统派和历史社科派;前者认为历史就是史学界内部和外部人士对各种史料来源的评论,后者则认为历史的研究是具体方法的研究。
The standardized ecational or psychological tests that are widely used to aid in selecting, classifying, assigning, or promoting students, employees, and military personnel have been the target of recent attacks in books, magazines, the daily press, and even in Congress. 广泛用来帮助选择、分类、指定或者激励学生、雇员和军队人员的标准化教育或心理测试是近来书刊、杂志、日报社甚至是国会攻击的目标。71) Thetarget is wrong, for in attacking the tests, critics divert attention from the fault that lieswith ill-informed or incompetent users.把标准化测试作为抨击目标是错误的,因为在抨击这类测试时,批评者未注意到其弊病在于那些对测试不甚了解或使用不当的使用者。The tests themselves are merely tools, with characteristics that can be measured with reasonable precision under specified conditions.这些测试本身只是工具,其特点能够在特殊的条件下相当准确地被估量。Whether the results will be valuable, meaningless, or even misleading depends partly upon the tool itself but largely upon the user.测试结果是否有价值、有意义,或者甚至误导人部分取决于工具本身,而大部分取决于使用者。All informed predictions of future performance are based upon some knowledge of relevant past performance: school grades, research proctivity, sales records, or whatever is appropriate.所有已知的对将来行为的预测都是基于对过去某些相关经验的了解的基础之上的:学校成绩、科研生产力、销售业绩,或诸如此类。72) How well the predictions will be validated by later performance depends uponthe amount, reliability, and appropriateness of the information used and on the skill and wisdomwith which it is interpreted.这些预测在多大程度上被后来的表现证实,这取决于被采用信息的数量、可靠性和适宜性以及解释这些信息的技能和才智。Anyone who keeps careful score knows that the information available is always incomplete and that the predictions are always subject to error.任何仔细记分的人都知道可用的信息总是不完整的,预测总是容易出现错误。Standardized tests should be considered in this context.标准化测试应该考虑在这样的环境中使用。They provide a quick, objective method of getting some kinds of information about what a person learned, the skills he has developed, or the kind of person he is.他们提供快捷、客观的方法以获取关于某个人学到了什么、他有哪些技能或者他属于哪种人的一些信息。The information so obtained has, qualitatively, the same advantages and shortcomings as other kinds of information.如同其他种类的信息,如此得来的信息在质量方面也是兼有优缺点。73) Whether to use tests, otherkinds of information, or both in a particular situation depends, therefore, upon the evidencefrom experience concerning comparative validity and upon such factors as cost and availability.因此,究竟是采用测试还是其他种类的信息,或是在某一特定情况下两者同时使用,须凭有关相对效度的经验依据而定,也取决于诸如费用和现有条件等因素。74) In general, the tests work most effectively when the qualities to be measured can be most precisely defined and least effectively when what is to be measured or predicted cannot be well defined.一般来说,当被测定的特征能够被很准确地界定时,测试最为有效;而当被测定或被预测的东西不能够被明确地界定时,测试的效果则最差。Properly used, they provide a rapid means of getting comparable information about many people.如果测试被恰当地使用,它们将提供一种快捷的方式来获取有关很多人的可比较的信息。Sometimes they identify students whose high potential has not been previously recognized, but there are many things they do not do.有时,通过它们(测试)还可以发现那些高潜质以前没有被发掘的学生,但许多事情是测试做不到的。75) For example, they do not compensate for gross social inequality, and thus do not tell how able an underprivileged youngster might have been had he grown up under more favorable circumstances.例如,测试并不弥补明显的社会不公;因此,它们不能说明一个物质条件差的年轻人,如果在较好的环境下成长,会有多大才干。试题分析1.[解析]本题考核的知识点:名词译为动词和介词语短的译法。这是一个主从复合句。主干为主系表结构带一个for引导的原因状语从句。主句翻译成“目标是错误的”含义不够清楚,根据上下文可知,the target应翻译成“把标准化测试作为抨击目标”。状语从句的主干是critics divert attention from…,直译为“批评家把注意力从弊病上移开”,意译为“批评家没有考虑其弊病”。The fault和其后的定语从句直译为“在于消息不灵通或不称职的使用者的错误”也不太符合中文的习惯,原因在于英文的名词使用频率比中文高,翻译时经常需要把名词转化为动词。users的动词是use,users前的形容词应相应地转为修饰动词的状语,可以译为“人们使用测试时对信息了解不够或使用不当”。In attacking the tests是介词短语做状语,译成状语从句时关键要看此介词短语在原句中起什么作用,然后再译成中文相应的状语从句。译文:把标准化测试作为抨击目标是错误的,因为在抨击这类测试时,批评者未考虑其弊病是来自人们对测试不甚了解或使用不当。2. [解析]本题考核的知识点:句子理解,代词指代。句子的主干是:How well…depends upon the amount, reliability, and appropriateness of… and (depends) on the skill and wisdom…。主语是how well开头的主语从句,其中使用了被动语态的将来时。“by+施动者”译成被动语态。depend后除了upon接了the amount, reliability, and appropriateness of the information做介词宾语之外,后头的the skill and wisdom with which 也是承接depend 而来,做on的介词宾语。with which引导的定语从句中it指代前文中的information,所以定语从句译成“解释这些信息的技能和才智”。词汇方面:validated的意思可以从形容词valid(有效的)推出,译为“证实”。译文:这些预测在多大程度上被后来的表现证实,这取决于被采用信息的数量、可靠性和适宜性以及解释这些信息的技能和才智。3.[解析] 本题考核的知识点:抽象名词的意译和代词指代。这是一个简单句。Whether to use… situation做主语;whether… or 意为“是……还是”; depends是谓语;evidence from和such factors as…共同做介词on的宾语。主语中的both根据上文应该指tests, other kinds of information两者;the evidence后有from experience修饰,experience又由一现在分词短语修饰;the evidence… validity可以译作“有关相对效度的经验依据”。译文:因此,究竟是采用测试还是其他种类的信息,或是在某一特定情况下两者同时使用,须凭有关相对效度的经验依据而定,也取决于诸如费用和现有条件等因素。4. [解析] 本题考核的知识点:状语从句的翻译和句子间的对比。该句由两个并列的主从复合句构成:the tests work most effectively when…and least effectively when…。两个分句由and 连接,and 之后的分句承前省略了主语和谓语the tests work。两个when都引导了时间状语从句,翻译时应置于主语之前。第二个状语从句中的主语是what 引导的名词性从句:what is to be measured or predicted,意为“被测定和被预测的东西”。词汇方面:work在这里意马心猿为“起作用”的意思;qualities是指被测人的素质;define意为“下定义,界定”。译文:一般地说,当被测定的特征能够被很准确的界定时,测试最为有效;而当被测定或被预测的东西不能够被明确地界定时,测试的效果则最差。5.[解析] 本题考核的知识点:虚拟语气,推测词义这是一个并列复合句。前一个分句的主语they指上文的the tests(本题所在段落中第二、三、四句的主语都承接第一句的主语tests,用they代替)。后一分句省略主语。由于两个分句成分相同时才会省略,因此这里省略的主语就是they(指测试)。Tell后的宾语从句用的是虚拟语气,表示对过去情况的虚拟;had he grown up 即if he had grown up。翻译时虚拟句中的条件从句应该放在其主句之前。词汇方面:gross在这里意为“明显的”;tell在此意为“判断、说明”;underprivileged 是一个需要用词汇学知识去推测词义的词,under(在……下)+privilege(特权),意为“在特权之下”,即物质条件不好,也可以结合条件句中的favorable circumstances(好的物质环境)的反义猜出词义;how able可以译作“有多能干,有多大的才干”。译文:例如,测试并不弥补明显的社会不公;因此,它们不能说明一个物质条件差的年轻人,如果在较好的环境下成长,会有多大才干。
