Evolution: Fact, Theory, Controversy
When biologists refer to the theory of evolution, they use the word“theory” as it is used throughout science. It does not mean a mere speculation or an unsupported hypothesis. The complex body of principles that explain evolutionary change is a theory in the same sense as“quantum theory” in physics or “atomic theory” in chemistry: it has been developed from evidence, tested, and refined, and it accounts for literally thousands of observations made throughout the entirety of biological science and paleontology.
Like all scientific theories, the theory of evolution is a current best explanation. It has withstood innumerable tests and attempts to disprove it, but it is still being refined, modified in the light of new knowledge, and extended to account for newly discovered phenomena. The theory of genetics has had such a history, progressing from Mendel’s simple early principles to the complex body of molecular principles that constitute today’s theory of inheritance, and it is constantly being refined and modified, even though its core principles have remained valid for a century. So it is with the theory of evolution.
Is evolution also a fact? All but the most trivial facts begin as untested hypotheses—such as the hypothesis that the earth revolves around the sun. They acquire “facthood” as more and more evidences accrue in their favor, and as they withstand attempts to refute them. The evidence and attempt at refutation may take many forms besides simple observations; indeed, the most powerful evidence is not mere observations, but conformity to predictions that the hypothesis makes about what we should see if the hypothesis is true or false. We do not observe the earth making a circuit around the sun; we accept this hypothesis because of the numerous, verified astronomical observations—and more recently observations from spacecraft—that conform to the predictions of the hypothesis. So Copernicus’s hypothesis is now a fact—a statement supported by so much evidence that we use it as if it were true.
Biologists accept as fact that all organisms, living and extinct, have descended, with innumerable changes, from one or at most a few original forms of life. For Darwin in 1859, this was a hypothesis, for which he provided abundant evidence from comparative anatomy, embryology, behavior, agriculture, paleontology, and the geographic distributions of organisms. Since that time, all of the many thousands of observations in each of these areas have supported Darwin’s core hypothesis. To these observations has been added copious evidence that Darwin could hardly have dreamed of, especially from paleontology and molecular biology. A century’s accumulation of such evidence establishes descent, with modification, from common ancestors as a fact of science. How we explain this fact—what the principles and causes of it may be—is the theory of evolutionary process, parts of which are subject to various amounts of scientific debate, modification, and extension.
To claim evolution as a fact is to confront controversy, for probably no claim in all of science evokes as much emotional opposition as biological evolution. Nonetheless, no scientific hypothesis other than common descent with modification can account for and make predictions about the unity, diversity, and properties of living organisms. No other hypothesis of the origin of biological diversity is supported by such overwhelming evidence, and no competing hypothesis spawns such richness of scientific study and has as many implications for the biological sciences and their applications to societal needs.

课文参考译文
进化:事实、理论、争论
当生物学家提到进化理论的时候,他们使用“理论”这个字眼,就像整个科学界所使用的那样。理论并不意味着它仅仅是推测,或者是未经证实的假设。解释进化的一批复杂原理是理论,其道理就像物理学中的“量子理论”和化学中的“原子理论”一样:理论是从证据发展而来的,经过了试验和提炼。理论实际上可以解释整个生物科学和古生物学中成千上万的观察情况。
像所有的科学理论一样,进化论是目前最好的解释。进化论经住了无数次试图推翻它的试验和尝试,但是进化论仍在根据新的知识进行提炼和修改,并得到扩展,以解释新发现的现象。遗传学理论就有过这样的历史,从孟德尔的简单早期原理发展到构成今天遗传理论的复杂的分子原理,虽然它的核心原理在一个世纪内仍然有效,它也在不断被提炼和修改。进化论也是如此。
进化也是事实吗?差不多最琐碎的事实在开始时都是未经试验的假设,如地球围绕太阳转的假设。随着有利于假设的证据越积越多,随着那些假设经受住了试图驳倒它们的努力,假设就具有了“事实特征”。除开简单的观察之外,证据和驳斥假设的尝试可能采取许多形式:确实,最有威力的证据不仅仅是观察,而是与这个假设所作的预言一致,这个预言的内容是,如果假设为真或假,我们观测到的事实是怎样的。我们不能观察到地球围绕太阳运行;我们接受这个假设是因为许多业已证实的对天体的观察——最近从宇宙飞船上的观察——是与有关这个假设的预言一致的。所以,哥白尼的假设现在已成为事实——这个说法得到这么多证据的支持,因此我们使用它好像它是真的一样。
生物学家认为,所有活着或灭绝的有机体——尽管有无数的变化——都起源于一个或者至多也只是少数几个原有的生命形式是事实。在1895年对达尔文来说,这是一个假设,他从比较解剖学、胚胎学、行为学、农学和古生物学以及有机体的地理分布角度提供了丰富的证据。自从那时以来,在所有这些领域的每个领域的数万个观察都支持达尔文的核心假设。在这些观察之外又加上了达尔文连做梦都想不到的丰富证据,尤其是来自古生物学和分子生物学的那些证据。一个世纪以来积累的这类证据表明,生物虽有变异,但起源于共同的祖先,这是一个科学事实。我们如何解释这个事实——不管其原理和产生的原因如何——就是进化过程的理论,这个理论的一些部分都要经过各种科学辩论、修改和扩展。
断言进化过程是一个事实就会招致争议,因为在科学领域内,也许没有任何论断像生物进化那样会招致如此多情感上的DIZHI。虽然如此,除了生物虽然有变异但有共同的起源这一科学假设以外,还没有其他的假设能解释生物体的一致性、多样性和诸多特征,并对它们做出预测;没有其他有关生物多样性起源的假设得到如此雄辩的证据的支持;没有其他假设促进了如此丰富的科学研究的产生,对生物科学及其在满足社会需要上的应用具有如此多的意义。
Ⅰ. Cloze
Men of science assume two types of evolution for man. Biological evolution is an evolution 1 the process of nature has produced without the 2 of man himself and without his asking for it. 3 this respect there is no difference between man and other animals, 4 every animal has reached a stage of evolution by a natural and coercive process. The same process has 5 man to the stage that we call him a human being, and consider him a specific kind of species as 6 from other species.
The social evolution means a new process of evolution 7 which nature does not 8 the role it did in man’s biological evolution. This evolution is an 9 one, namely, an evolution that man has secured by his own 10 , and in every period has transferred it to the next 11 through teaching and learning, and not through heredity.
There is no doubt that human society since its 12 , that is, since civilization first began to appear, has continuously progressed and evolved. We all know that 13 the biological evolution, social evolution, too, has been 14 , with one difference, and that is, with the passage of time the rate of evolution has increased in speed; in other words, it has followed a course of 15 . It has moved on and on and has not been 16 .
If we do not understand the direction of evolution and man’s 17 goal, we cannot speak of evolution, but merely state that man is progressing; 18 then, immediately, the question 19 : towards what? If we cannot answer this question, there is little 20 for us to speak of evolution.

Part A 阅读理解
★ Passage One
Natural selection is the ultimate cause of adaptations, but it cannot produce such adaptations unless mutation and recombination generate genetic variation on which it can act. Over a long enough time, new mutations and recombinations, sorted by genetic drift or natural selection, can alter many characteristics, and can alter each characteristic both quantitatively and qualitatively. The result can be a indefinitely great change, so great that a descendant species differs strikingly from its remote ancestor.
Although each of the separate process involved in evolution seems relatively simple, evolution is not as straightforward as this summary might make it appear. The various processes of evolution interact in complex ways, and each of them itself has many nuances and complexities. 1)One gene may affect several characters, several genes may affect one character, natural selection may change in rate or even direction from year to year, or conflicting selection pressures may affect a character. When such complexities are taken into account, it can be quite difficult to predict when and how a character will evolve. Mathematical theory and computer modeling are invaluable tools for understanding how the evolution of a character is likely to proceed. A great deal of evolutionary research consists of formulating precise, often quantitative models, then testing them by experiment or observation.
It is important to distinguish between the history of evolution and the processes held to explain this history. Most biologists regard the history of evolution—the proposition that all species have descended, with modification, from common ancestors—as a fact—that is, a claim supported by such overwhelming evidence that it is accepted as true. The body of principles that describe the causal processes of evolution, such as mutation, genetic drift, and natural selection, constitute the theory of evolution. 2)“Theory” is used here as it is used throughout science, as in “quantum theory” or “atomic theory,” to mean not mere speculation, but a well-established system or body of statements that explain a group of phenomena. Although most of the details of the history of evolution remain to be described (as is true also of human history), the statement that there has been a history of common ancestry and modification is as fully confirmed a fact as any in biology.
In contrast, the theory of evolution, like all scientific theories, continues to develop as new information and ideas deepen our understanding. Evolutionary biologists have great confidence that the major causes of evolution have been identified. However, views on the relative importance of the various processes continue to change as new information adds detail and modifies our understanding. Yet, to cite evolution as a fact can invite controversy, for probably no claim in all of science evokes as much emotional opposition.

★ Passage Two
The Biophysical Society is deeply troubled by attempts in the United States to suppress the teaching of evolution in public schools, or to temper the teaching with disclaimers, or to present evolution as only one of several alternative theories about the origin of human life on earth.
As biophysicists, we are engaged in studying the structure and function of living organisms at a molecular level. Such studies have demonstrated that all life forms on earth obey the laws of chemistry and physics, and that these life forms are built from molecules that show common origins. 3)The hypothesis that binds all these studies, built upon an immense body of evidence accumulated from geology, paleontology, biochemistry and molecular biology, is the theory of evolution. The main mechanism for evolutionary change is genetic variation. Scientists have demonstrated how at the molecular level, imperfections in DNA replication and damage to DNA caused by sunlight and radiation can contribute to genetic variability. One need only look at the progression of influenza to see evolution in action today.
In contrast to the scientific picture of evolution that has emerged from field observations and laboratories, there are some today who argue that alternative views, such as Biblical Creationism or Intelligent Design, should be taught instead of evolution, or alongside evolution in classrooms. 4)What distinguishes scientific theories from these theological beliefs is the scientific method, which is driven by observations and deductions, leads to testable predictions, and involves the formulation of hypotheses that can be refuted. This process results in a body of facts that have been repeatedly confirmed by experiments, which in turn result in a theory. Scientific theories are therefore not “guesses,” but fact-supported, self-consistent, reliable accounts of the world. The alternative theological explanations for origins are not based on the scientific method, and are, therefore, not in the realm of science. They are in the realm of faith.
The Biophysical Society is strongly opposed to any effort to blur the distinction between science and theology by teaching or presenting non-scientific beliefs in science classrooms. Accepting the evidence that evolution has and continues to take place does not preclude one from believing in theologies, but those beliefs have no place in a science curriculum. Attempts to suppress or compromise the teaching of evolutionary science in the United States are misguided actions that will deprive our youth of a clear understanding of the scientific process, and of the scientific skills that they need to compete in a global economy: one that is increasingly driven by science and technology. Moreover, current efforts to disguise theology as science do a severe disservice to the scientific profession and to the people of the United States.
1. The Biophysical Society feels upset by all of the following practices in public schools except .
[A] the prohibition of evolution teaching
[B] the reluctance to teach evolution
[C] the debate about how evolution is taught
[D] the presentation of competitive theories about the origin of life
2. Genetic variation might be caused by .
[A] evolutionary change [B] contracting influenza
[C] radioactive damage to DNA [D] imperfect DNA transfer
3. According to the writer, the idea of Intelligent Design .
[A] should be taught in addition to the theory of evolution
[B] is not formulated on the basis of the scientific method
[C] is a theological belief that should be abandoned by all
[D] offers a strongly competitive version about the origin of life
4. One of the serious consequences from teaching creationism in schools is that .
[A] more students will turn to religious beliefs
[B] students will not take evolution seriously
[C] students may fail to grasp the scientific method
[D] students will be reluctant to follow the scientific profession

Part B 选择搭配
Directions:
In the following article, some sentences have been removed. For Questions 1~5, choose the most suitable one from the list A~G to fit into each of the numbered blanks. There are two extra choices which do not fit in any of the gaps.
In the context of the recent panic over the growth rate of the Muslim population in India, recent international data on “human development” in India and Bangladesh make interesting reading. Surely, India must be far ahead of Bangladesh in this respect?
Indeed, Bangladesh is not only poorer (much poorer) than India, but also saddled with a large Muslim population. India, for its part, is now a “superpower”. One would, therefore, expect its citizens to be much healthier, better fed and better educated than their Bengali neighbours.
1) .
This is all the more interesting as the positions were reversed not so long ago: in 1990, the infant mortality rate was estimated at 91 per 1,000 in Bangladesh, and 80 per 1,000 in India. India has been neatly leap-frogged, that too during a period when economic growth was much faster in India than in Bangladesh.
2) .
Similarly, 97 per cent of the population in Bangladesh have access to an “improved water source,” compared with 84 per cent in India; and 48 per cent of Bangladeshis have access to “improved sanitation,” compared with 28 per cent of Indians.
For good measure, the maternal mortality rate is much higher in India than in Bangladesh: 540 and 380 per 100,000 live births, respectively. Contraceptive prevalence, for its part, is higher in Bangladesh than in India—the “wrong” ranking again!
3) .
The reverse applies to military expenditure, also known as “defence”: 2.3 per cent of GDP in India compared with 1.1 per cent in Bangladesh. So much for health. But in education at least, India must be way ahead? Can Bangladesh boast a fraction of India’s Nobel prizes, famous writers, nuclear scientists, eminent scholars?
4) .
Some of these estimates may not be very accurate. Perhaps the ranking would be reversed, in some cases, if exact figures were available. But the general pattern, whereby Bangladesh is now doing better than India in terms of many aspects of social development, is unlikely to reflect measurement errors.
5) .
Bangladesh is no paradise of human development. Like India, it is still one of the most deprived countries in the world. However, social indicators in Bangladesh are improving quite rapidly, while in India, social progress is slower and less broad-based, despite much faster economic growth. This is one indication, among many others, that India’s development strategy is fundamentally distorted and lopsided.
[A] Perhaps all this has something to do with the fact that public expenditure on health as a proportion of GDP is almost twice as high in Bangladesh (1.6 per cent) as in India (0.9 per cent).
[B] Yet, let us examine the evidence. A good starting point is the infant mortality rate: 51 per 1,000 live births in Bangladesh compared with 67 per 1,000 in India, according to the latest Human Development Report. In other words, infant mortality is much lower in Bangladesh.
[C] The overall picture for social progress in the world is grim, with 21 African and Asian countries nearing social collapse due to concentrated poverty, weak political institutions, repeated economic failure, disease and cultural isolation.
[D] This pattern is all the more striking as India used to fare better than Bangladesh in all these respects not so long ago—say in the early 1970s , when Bangladesh became independent.
[E] The last decade has seen a sharp deterioration in overall life quality for vast segments of the world’s population, especially for people living in the poorest nations of Africa and Asia. Even people in previously well-off countries are not doing as well today.
[F] Other indicators relating to child health point in the same direction. According to the same Report, 95 percent of infants in Bangladesh are vaccinated against tuberculosis, and 77 per cent are vaccinated against measles. The corresponding figures in India are only 81 per cent and 67 per cent, respectively.
[G] Perhaps not, but Bangladesh appears to be closer to universal primary education than India: it has achieved a “net primary enrolment ratio” of 87 per cent, higher than India’s 83 per cent. What is more, Bangladesh has eliminated the gender bias in primary education, in sharp contrast with India where school participation rates continue to be much higher for boys than for girls.

Ⅰ. Cloze
1.[D] that
本题考句子结构。主句是完整句:Biological evolution is an evolution;从句the process of nature has produced,故应选引导定语从句的关系代词that。
2.[B] intervention
本文主要讨论社会进化,根据本句“自然过程产生的”及下文中对另一种不同进化方式(the social revolution)的阐述,可知生物进化过程没有人类的干预,故选intervention(干涉,干预)。其余选项均与文意无关:adaptation,“适应,调节,改编”;disruption,“中断,破坏,瓦解”;innovation,“创新,革新”。
3.[B] In
本题考搭配。in this respect是常用词组,意为“在这个方面”,与in this regard是同义词。其余介词均不适用。
4.[A] since
本题考句间逻辑关系。从句意为“每一种动物都经过自然的过程被强迫进化到了一个阶段”,是主句“在这个方面人与其他动物没有区别”这一结论的依据,故选择表示因果关系的连词since(既然,由于)。其余选项均不适用:although(尽管)表示逻辑转折;as long as(只要,以……为条件)引导条件状语,unless(除非)表示“如果不”。
5.[C] brought
bring...to有“引起,导致,或迫使……进入一特定的状态、情形或位置”等意思,brought man to the stage that we call him a human being即“使人类进化到我们称之为人的阶段”。其余选项均需用其他句型表达,如:The same process has caused man to develop into the stage that.../ has resulted in man’s reaching the stage that.../has gradually made man what we call a human being.
6.[A] distinct
生物进化到一定程度,就产生了区别于其他物种的人类。distinct有“清楚的, 明显的, 截然不同的, 独特的”等意思,通常与介词from连用,是正确答案。其余选项均不适用:diverse,“不同的,多种多样的”;contradictory,“反驳的,矛盾的”; conflicting,“相冲突的,不一致的,矛盾的”。
7.[C] in
定语从句中关系代词which指代主句中的a new process of evolution,故需选用介词in,表示“在此过程中”。
8.[D] play
本题考动宾搭配。to play the role是固定用法,意为“担任角色,起作用”。其余选项在此均不适用。
9.[D] acquired
根据上文所描述的与生物进化过程的不同以及本句后半句namely引出的同位语解释,可以推知此处应当讲社会进化需要靠人类自己的意愿和努力完成;acquired与hereditary(遗传的)为对应词,意为“学到的,通过自己的努力得到的”,符合文意。其余选项均不合文意:altered,“更改的,改编的”;abandoned,“放弃的,遗弃的”;accomplished,“完成的,多才多艺的”。
10.[C] effort
本段描述与依靠自然选择的生物进化不同的新的人类进化形式(a new process of evolution)。secure有“确保,取得”等意思,effort意为“努力”,secured by his own effort即“通过自己的努力才获得”,是正确答案。其余选项均不能表示与生物进化的对比:course,“进展,进程,行为”;growth,“成长”,right,“权利,正义”。
11.[D] generation
本句中时间状语in every period和表示强调的否定式词组not through heredity限定本题只能选generation(一代人)才合文意:“并且在各个阶段都通过传授和学习,而不是通过遗传的方式传递给下一代” 。其余选项均不适用:era,“时代,纪元”;interval,“间隔,幕间休息,距离”;episode,“插曲,一段情节,(电视连续剧的)一集”。
12.[B] origin
根据that is引出的同位语since civilization first began to appear提示,此处应当讲人类的起源,故选origin(起源,事物出现的始点)。initiation(启动,发起,启蒙)和commencement(着手,起动,毕业典礼)虽然也有“开始”的意思,但一般不用于论述“物种的起源”;founding意为“建立,创建”,一般用于描述人为的活动。
13.[A] like
根据本句中插入语too和with one difference可知在此应讲两种进化的相同,故应填介词like(像……一样)。
14.[A] gradual
众所周知,人类进化过程漫长缓慢,gradual有“逐级的,逐步的;规则地或连续地发展或前进的”等意思,符合文意。其余选项均不适用:deliberate意为“蓄意的,深思熟虑的”,不能描述自然选择过程;intermittent意为“间歇的,断断续续的”,与上文continuously progressed and evolved不符;radical主要指“激进的,极端的,根本的”,亦非人类进化模式。
15.[B] acceleration
过渡词in other words提示,本句应重述分号前句的内容,acceleration意为“加速”,符合文意:“随着时间的流逝,进化的速度加快了;换言之,进化是一个不断加速的过程。”其余选项均不合逻辑:expansion,“扩充,扩张,展开”;accumulation,“积累,聚集”;modernization,“现代化”。
16.[C] stationary
由and连接的并列谓语用肯定和否定方式重述“人类进化过程没有停顿”这一思想。stationary意为“固定的,静止的,不变的”,符合文意。其余选项均不合逻辑:progressive,“进步的,前进的”;vigorous,“有活力的,精力充沛的”;deteriorating,“恶化的,衰退的”。
17.[D] ultimate
本段讲由人类自我意识决定的社会进步需要明确目标,ultimate意为“最终的,根本的”,符合文意。其余选项均不能表达“最高,极限”的意思:prominent,“卓越的,显著的,突出的”;optional,“任选的,非强制的”;terminal“末端的,最终的,晚期的”。
18.[B] for
本题考上下文逻辑。分号后面解释为什么不了解人类社会往何处去和要达到的最终目标就只能说人类正在前进而无法真正谈论进化,故选for引出原因:“因为那样就会立刻产生‘向何处前进’的问题。”
19.[A] arises
本题考主谓搭配。arises 有“形成,发生,出现,产生”等意思,其余选项均不正确:proposes,“提议,推荐,求婚”;reveals(显露,暴露)和creates(创造,引起)都是及物动词。
20.[C] point
point有“(值得达到或取得的)目标或目的”等意思;there is little (no)point for somebody to do something是常用表达,意为“某人做某事没有多少(毫无)意义”。其余选项均无此用法。
◎ Ⅱ. Reading Passages
Part A 阅读理解
Passage One
1.[A] 意为:遗传变异。
第一段提到,虽然自然选择是导致适应性变化的最终原因,但是,如果没有(基因的)突变和重组导致遗传变异,使它可以作用于其上,自然选择就不能产生这些适应性变化。在足够长的时间之后,经过遗传漂变或自然选择过程的筛选,新的突变和重组能改变许多特征,并且能使每一个特征发生量变和质变。结果可能导致巨大的变化,以至于某个物种的后代与其遥远的祖先有显著的差别。可见,没有变异的产生,自然选择就没有作用的基础,也就没有生物发生适应性变化,即没有进化。
[B] 意为:遗传漂变。
[C] 意为:行为的改变。
[D] 意为:适应的速度。
2.[A]意为:进化过程的复杂性。
第二段第四句提到,考虑到有这些复杂性,要预测某个特征什么时候开始进化以及如何进化,就相当困难。这里,such complexities指进化过程的复杂性。
[B] 意为:进化过程中发生的大量变化。原文强调的是进化方式的复杂性,而不是变化的数量。
[C] 意为:每种理论模式所提出的相互冲突的解释。
[D] 意为:缺乏有效的设备模拟进化过程。
3.[B]意为:后者是一个公认的事实。
第三段提到进化论和进化历史的区别。第三段最后一句总结说:虽然进化历史过程中的多数细节还有待于被进一步去记述(正像是美国历史的一些细节问题一样),但是,生物起源于一个共同的祖先,之后才发生了变异,这种论断正像是生物学中的一些论断一样,已经完全被确立为一个事实。该段第二句也提到,许多生物学家把进化的历史看作是一个事实。另请参阅第四段作者对进化理论的论断。
[A] 意为:后者可能被否定。
[C] 意为:前者是一个公认的事实。
[D] 意为:前者只是一些原理。
4.[D]意为:各种过程在进化中的相对重要性。
最后一段提到,相比之下,像其他科学理论一样,随着新的信息和思想不断深化着我们的认识,进化的理论将继续发展。研究进化过程的生物学家坚信,他们已经找到了进化的主要原因,但是,随着新的信息提供更多细节并改变我们的认识,各种进化过程的相对重要性还会改变。可见,在作者看来,随着人们对进化过程产生更深刻的认识,人们对什么因素在导致生物进化中起主要作用,还会产生新的认识。换言之,哪些进化过程起到了更重要的作用,还是一个值得进一步证实的问题。
[A] 意为:产生遗传变异的突变和重组。
[B] 意为:对导致进化的主要原因的确认。
[C] 意为:所有生物虽然发生了变异但起源于一个共同祖先。
5.[D]意为:经常带有感情色彩而不是科学的态度。
在最后一句作者指出,断定进化是一个事实就会引起争议,因为在科学领域还没有任何一种论断(像进化论一样)引起如此多感情上的DIZHI。这里的含义是:人们对进化论的DIZHI经常是一种情感反应。
[A] 意为:可以轻易地被新的发现推翻。
[B] 意为:没有获得科学界的支持。
[C] 意为:在当今社会通常被看作是荒唐的。
Passage Two
1.[C] 意为:有关如何讲授进化论的争论。
第一段提到,在美国,有些人企图在公立学校压制进化论的教学(选择项[A]表达的内容),或者宣布自己对进化论的教学不承担责任(选择项[B]表达的内容),或者把进化论当做有关地球上人类起源的几种理论中的一种来讲授(选择项[D]表达的内容),这些做法使生物物理学协会深感不安。
[A]意为:禁止进化论的教学。
[B]意为:不愿意讲授进化论。
[D]意为:讲授有关生命起源的其他理论。
2.[C]意为:对DNA的放射损伤。
第二段提到,导致进化过程中的变化的主要机制是遗传变异。科学家已经证明,在分子水平上,DNA在复制过程中产生的缺陷,阳光和辐射对DNA造成的损伤,都可能导致遗传变异。我们只要看看流感的进程就能观察到活生生的进化过程。
[A]意为:进化过程中的变化。
[B]意为:感染流感。
[D]意为:有缺陷的DNA传递。
3.[B]意为:不是基于科学的方法而形成的。
参阅第三段第二句和该段最后两句。
[A]意为:应该同进化论一起讲授。
[C]意为:是人们都应该摒弃的一种宗教信仰。
[D]意为:对生命的起源提供了一种有很强竞争力的理论。
4.[C]意为:学生可能掌握不了科学方法。
最后一段提到,在美国,企图压制或调和进化论科学的教学是误导人的做法,这会剥夺我们的年轻人清楚地理解科学过程的权利,使他们无法获取在全球经济竞争中所需要的科学技能,而全球化经济的形成越来越受到科学技术的驱动。而且,目前把神学伪装成科学的做法,对科学界和美国人民造成了严重的伤害。
[A]意为:更多的学生会转向宗教信仰。
[B]意为:学生不会认真对待进化论。
[D]意为:学生将不愿意从事科学方面的职业。
5.[A]意为:一项声明。
本文是生物物理学协会就美国公立学校中进化论的教学状况所发表的一篇声明。这由第一段、第二段第一句、第四段第一句可以清楚地看出。
[B]意为:一篇社论。
[C]意为:一篇科学报告。
[D]意为:对一个事件的评述。
Part B 选择搭配
1.[B]
此处结合上下文来考虑。上文主要讲,与印度相比,巴基斯坦不仅穷得多,而且拥有大量的穆斯林人口。印度可称为一个“超级大国”。因此,人们会认为印度国民比其巴基斯坦邻居更丰衣足食、接受更好的教育。而下一段开头讲,这些情况在不久前被颠倒过来。由此可知,所空缺这一段是讲事实与人们预期的不同,应与上文有转折的关系。[B]符合这一点,意为:但是让我们来看看证据。一个很好的出发点就是婴儿死亡率:在巴基斯坦每1 000名新生婴儿死亡51名,而在印度则为每1 000名死亡67名。换言之,巴基斯坦婴儿死亡率低得多。
2.[F]
此处仍是考虑上下文意思的连贯。上文讲,在1990年,印度的婴儿死亡率比巴基斯坦低得多,而同一时期经济增长也比巴基斯坦快得多。下一段开头用Similarly引出,可知仍是在讲现在被颠倒过来的事实,即印度已落后于巴基斯坦:巴基斯坦人口的95%可以有“改善的水源”,而印度则只有84%;48%巴基斯坦人可以享有“改善的卫生条件”,而印度只有28%。由此可知,所空缺这一段也是在讲印度已落后于巴基斯坦的一些方面。[F]可以承上启下,意为:与儿童相关的其他指标情况也是一样。根据该《报告》,巴基斯坦95%的婴儿都注射肺结核疫苗,77%的婴儿注射麻疹疫苗,而印度相应的数字分别只有81%和67%。
3.[A]
根据上下文,上文都是在讲两国相比较的事实,下一段开头的The reverse是关键信息词,意为:用于军事花费,也就是所谓的“国防”的花费是反过来的:印度的军费占GDP的2.3%,巴基斯坦的军费则只占GDP的 1.1%。由此可知,所空缺这一段是讲在某一方面的花费问题,即[A],而且[A]开头all this与上文也是连贯的,意为:也许所有这一切都与这一事实有关:巴基斯坦用于卫生健康方面的公共花费所占GDP的比例(1.6%)几乎为印度(0.9%)的两倍。
4.[G]
此处结合上文来看。上段最后为问句:在教育方面,印度一定会领先?巴基斯坦能自豪地称自己拥有相当于印度一小部分的诺贝尔奖、著名作家、核科学家、杰出学者吗?[G]开头正好是对此问题的回答:也许不能,但是,巴基斯坦似乎比印度更为普及小学教育:它已经实现了87%的小学入学率,高于印度的83%。另外,巴基斯坦在小学教育中已经根除了性别歧视,这与印度形成鲜明对照,在印度男孩入学率持续比女孩入学率高得多。
5.[D]
根据上段最后一句:但是,总的形势(the general pattern)即巴基斯坦在社会发展的许多方面都比印度做得好,测量数据不可能是有错的。而[D]开头的This pattern正好与此衔接起来,意为:这一形势更加令人震惊,因为在不长时间前——如20世纪70年代巴基斯坦刚独立时,印度一直在所有这些方面都远远好于巴基斯坦。
**[C]和[E]是干扰项。[C]意为:全世界社会进步的总体画面是很严酷的,由于集中的贫穷、无力的政治制度、反复的经济失败、疾病及文化的孤立,有21个非洲和亚洲国家几近社会崩溃的边缘。[E]意为:前十年世界人口很大的一部分都经历了生活质量大幅下降的情况,尤其是居住在非洲和亚洲最贫穷国家的人们。即使那些以前曾经很富裕的国家的人们现在生活得也不如从前。这两个选项都是在讲整个世界范围内的情况,不符合本文主题。
◎ Ⅲ.Translation
1.这是四个并列的简单句,大部分由逗号连接。本句应译成:一个基因可能影响一些特征,几个基因可能影响一种特征,自然选择可能在速度、甚至在方向上年复一年地变化,或者说,彼此冲突的选择压力可能影响一种特征。
2.这是一个简单主从复合句,句架是“Theory”is used...as it is..., as in...“atomic theory,”to mean not mere speculation,but a...system or body of statements that...。前面的as it is used throughout science是方式状语从句;后面的that explain a group of phenomena是一个定语从句,修饰body of statements。本句应译成:就像在整个科学界所使用的那样,像在“量子理论”或“原子理论”中那样,在这里使用“理论”这个字眼的意思,不是指纯粹的推测,而是指得到公认的一个体系,或一批论断,能用它来解释一些现象。
3.这是一个简单主从复合句,句架是 The hypothesis that..., built upon..., paleontology,biochemistry and...,is the theory of evolution。句中that binds all these studies 是修饰hypothesis的定语从句,built upon是过去分词,修饰hypothesis。本句应译成:把所有这些研究结果结合在一起的这种假说就是进化论。而这些研究结果则是以地质学、古生物学、生物化学和分子生物学所积累的大量证据为基础的。
4.这是一个简单主从复合句,句架是What...is the scientific method,which..., ..., and...。关系代词which引导非限制性定语从句,修饰前面整个句子。在定语从句中,is driven, leads to,involves是三个并列的谓语动词。that 是关系代词,引导定语从句,修饰 the formulation of hypotheses。 本句应译成:把科学理论同这些神学信仰区分开来的是科学方法,科学方法在观察和推论的推动下,导致可测试的预测的产生,促进了一些可被推翻的假设的形成。

Part A 应用文
Dear Xiaogang,
I’ve arrived in Beijing only for a few hours, but I’m already anxious to tell you my first impression on Beijing,that is, the extremely heavy traffic.
I admitted that traffic in Beijing was heavy 20 years ago when I worked here.Usually we had to carefully avoid the rush hours.But now we can observe no obvious rush hours,for there are traffic jams eveywhere at anytime of the day!
I cannot help pondering on the situation.The increasing number of private cars must have been a major cause.Perhaps something has to be done about this.
More later,and take care.
Yours,
Jack
Part B 英语写作
Great changes have taken place in people’s living conditions, especially in housing in China. As the two contrasting pictures describe, it was quite difficult for Chinese people to have houses of their own in the past. They could only live in dormitories or in rented houses. But now, many of them have moved into new and spacious apartment houses.
The change can be attributed to many factors. With the development of economy and the progress of society, people’s living standard has been greatly improved. One consequence is that their ability to purchase private houses is considerably enhanced. What they could hardly imagine in the past can be fulfilled today. In addition, the rapid development of real estate stimulates people’s desire for the ownership of their own houses. Furthermore, certain policies formulated by the government give people privileges when they buy houses. For instance, banks grant a large amount of loans to people. Also, the state allocates huge funds for the building of economical houses ordinary people can afford.
Whatever the reason, changes in people’s living conditions serve as a symbol of social development in China. However, more efforts should be made so that it will not be long before people in all areas of the country can better their lives. |
