01. That sex ratio will be favored which maximizes the number of descendants an individual will have and hence the number of gene copies transmitted. 那种性别比例能在最大程度上增加一个个体所能拥有的后代数量，并因此能在最大程度上增加所传递到后代身上去的基因复制品的数量。
02. A desire to throw over reality a light that never was might give away abruptly to the desire on the part of what we might consider a novelist-scientist to record exactly and concretely the structure and texture of a flower . 照亮现实的欲望，此欲望从来就不会唐突的取代后面的那种欲望，后者是我们可以将其部分的理解为一个兼任小说加和科学家的人想要去准确并具体的记录下一朵花的结构和文理的那种意义上的欲望。
03. Hardys weakness derived from his apparent inability to control the comings and goings of these divergent impulses and from his unwillingness to cultivate and sustain the energetic and risky ones. 哈代的缺陷一方面缘起于他的某种明显的无能，无法控制好那结不尽相同的创作冲动的穿梭往来;另一方面缘起于他不愿意去培养和维持那些富于生机活力和风险性强的创作冲动。
04. Virginia Woolfs provocative statement about her intentions in writing Mrs. Dalloway has regularly been ignored by the critics，since it highlights an aspect of her literary interests very different from the traditional picture of the poetic novelist concerned with examining states of reverie and vision and with following the intricate pathways of individual consciousness. 弗吉尼亚.伍尔夫在创作《黛洛维夫人》时有关其创作意图的这番发人深思的陈述，迄今为止一贯为文学评论家们所忽略，因为它突出反映了她诸多文学兴趣中某一方面，而这一方面则与人们对诗性小说家所形成的传统见解大相径庭。所谓的诗性小说家，所关注的是审视想入非非和白日梦幻的诸般状态，并致力于追寻个体意识的通幽曲径。
05. As she put it in The Common Reader , It is safe to say that not a single law has been framed or one stone set upon another because of anything Chaucer said or wrote ; and yet , as we read him , we are absorbing morality at every pore . 就像她在《致普通读者》一书中所表达的那样，尽管可以毫无疑问的说，没有任何法律被指定出来，也没有任何高楼大厦被建立起来是因为乔叟说了什么或者写了什么;然而，当我们读它的书的时候，我们身上每一个毛孔都充满了道德
06. With the conclusion of a burst activity , the lactic acid level is high in the body fluids , leaving the large animal vulnerable to attack until the acid is reconverted , via oxidative metabolism , by the liver into glucose , which is then sent back to the muscles for glycogen resynthesis . 随着爆发出来的运动的结束，再体液中乳酸含量会变得很高，使得大型动物处于容易受到攻击的状态，直到乳酸通过有氧新陈代谢，被肝脏转化成葡萄糖，而葡萄糖接下来又会传送回肌肉中重新合成糖原 .
07. Although Gutman admits that forced separation by sale was frequent，he shows that the slaves preference，revealed most clearly on plantations where sale was infrequent，was very much for stable monogamy. 虽然古特曼承认，由于奴隶买卖而造成的被迫离散甚为频繁，但他还是证明，奴隶的偏爱在那些奴隶买卖并不频繁的种植园上被最为显著地揭示出来在很大程度上侧重于稳定的一夫一妻制。
08. Gutman argues convincingly that the stability of the Black family encouraged the transmission of-and so was crucial in sustaining-the Black heritage of folklore,music,and religious expression from one generation to another，a heritage that slaves were continually fashioning out of their African and American experiences. 古特曼人令人信服地论辨道，黑人家庭的稳定有助于包括民间传说、音乐、及宗教表达在内的黑人文化遗产一代一代传递下去，因而在维持文化遗产方面也起着至关重要的作用，而对于这种文化遗产，黑奴们不断地从其非洲和美洲的经历中予以丰富发展。
09. This preference for exogamy，Gutman suggests,may have derived from West African rules governing marriage，which，though they differed from one tribal group to another，all involved some kind of prohibition against unions with close kin. 古特曼表示，这种对于外部通婚的偏爱很有可能缘起于西部非洲制约着婚姻的规定，尽管这些规定在一个和另一个部落群体之间不尽相同，但都涉及到某种对近亲联姻的禁止。
10. His thesis works relatively well when applied to discrimination against Blacks in the United States，but his definition of racial prejudice as racially-based negative prejudgments against a group generally accepted as a race in any given region of ethnic competition， can be interpreted as also including hostility toward such ethnic groups as the Chinese in California and the Jews in medieval Europe. 该社会学家的命题当被应用于针对美国黑人的歧视时，相对而言尚能适用，但他对种族偏见所下的定义即以种族为基础的、针对某个群体的消级的先入之见，而该群体在任何特定的种族竞争地区则被普遍认作一种族可被理解成同样也襄括了针对加利福尼亚州的中国人以及中世纪的犹太人这样一些种族群体的敌视态度。
11. Such variations in size， shape，chemistry， conduction speed， excitation threshold，and the like as had been demonstrated in nerve cells remained negligible in significance for any possible correlation with the manifold dimensions of mental experience. 类似于这些已经被在神经细胞中证明的在大小、形状、化学过程、产生的速度、兴奋阈值及其类似的方面上所发生变化，当他们被用来与大脑的体验以可能的方式联系起来的时候，他们在重要性上仍然是微不足道的。
12. It was possible to demonstrate by other methods refined structural differences among neuron types ; however , proof was lacking that the quality of the impulse or its condition was influenced by these differences , which seemed instead to influence the developmental patterning of the neural circuits . 有可能通过其他方法来证明神经元种类间的细微的结构差异;可是，这样的证据是缺乏的，即神经冲动的性质或者状态是受这些差异所影响的，而这些差异看起来却能影响神经网络的发育模式。
13. Although qualitative variance among nerve energies was never rigidly disproved，the doctrine was generally abandoned in favor of the opposing view，namely，that nerve impulses are essentially homogeneous in quality and are transmitted as common currency throughout the nervous system. 尽管在神经能量上存在着质的不同，这一点从来都没有在严格的意义上被反对过，但是以上教条通常被抛弃掉，而转向相反的观点，即：神经冲动从根本上本质相同，而且被当作一种普通流在整个神经系统中传播。
14. Other experiments revealed slight variations in the size，number， arrangement，and interconnection of the nerve cells，but as far as psycho neural correlations were concerned，the obvious similarities of these sensory fields to each other seemed much more remarkable than any of the minute differences. 尽管其他实验显示在神经细胞的大小、数量、排列和相互连接上有一些小的差异，但是就心理-神经的关系而言，这些感官区域彼此之间的明显的相似性看起来比起微小的差异更为令人注目。
15. Although some experiments show that，as an object becomes familiar，its internal representation becomes more holistic and the recognition process correspondingly more parallel，the weight of evidence seems to support the serial hypothesis,at least for objects that are not notably simple and familiar. 虽然某些实验表明，随着一个物体变得熟悉起来，其内心再现图像亦更具整体感，辨认过程相应地更趋于平行，但证据的砝码似乎在支持序列假设，至少是对于那些不甚简单、不甚熟悉的物体来说.
16. In large part as a consequence of the feminist movement，historians have focused a great deal of attention in recent years on determining more accurately the status of women in various periods. 在很大程度上，由于女权主义运动的缘故，史学家近年来汇聚了大量的注意力，来更为准确地确定妇女在各个历史时期的地位。 Focus A on B;
17. If one begins by examining why ancients refer to Amazons , it becomes clear that ancient Greek descriptions of such societies were meant not so much to represent observed historical fact -real Amazonian societies - but rather to offer moral lessons on the supposed outcome of womens rule in their own society . 如果我们先研究一下为什么古人会提到亚马逊人，下面的一点就变得清晰了，那就是古希腊对于这种社会的庙睡不是太多的被用来表达观察的历史事实真正的亚麻逊社会的而是为了对于妇女在其社会中的统治的预期后果提供一种道德教导.
18. Thus，for instance，it may come as a shock to mathematicians to learn that the Schrodinger equation for the hydrogen atom is not a literally correct description of this atom，but only an approximation to a somewhat more correct equation taking account of spin，magnetic dipole，and relativistic effects;and that this corrected equation is itself only an imperfect approximation to an infinite set of quantum field-theoretical equations. 因此，举例来说，对数学家而言，了解到下述情形可能会令其惊愕不已，即薛定谔的氢原子方程式并非是对该原子作出的一种绝然正确的描述，而仅仅是个近似值，趋近于一个在某种程度上更为正确的将自旋、磁性偶极子、以及相对论效应考虑在内的方程式;而这个得以纠正的方程式就其本身而言也只是一个不完美的近似值，趋近于无穷无尽的一整套量子场论方程式。
19. The physicist rightly dreads precise argument，since an argument that is convincing only if it is precise loses all its force if the assumptions on which it is based are slightly changed，whereas an argument that is convincing though imprecise may well be stable under small perturbations of its underlying assumptions. 物理学家恐惧于那些精确无误的论据不无道理，因为某种只有在它是精确无误的条件下才令人置信的论据，一旦它赖于建立其上的假设稍有变化，便会失去它一部的作用;而与此相反，一个尽管并不精确无误但却令人置信的论据，在其基本假设稍微受干扰的情况下，仍然有可能是站得住脚的。
20. However，as they gained cohesion，the Bluestockings came to regard themselves as a womens group and to possess a sense of female solidarity lacking in the salonnieres，who remained isolated from one another by the primacy each held in her own salon. 起初，蓝袜女们确实模仿了法国沙龙女主人，将男性襄括到其小圈子中来。然则，随着她们获得的凝聚力，她们渐趋将自己视作一女性团体，并拥有了一种妇女团结意识，而这种意识在法国沙龙女主人身上则荡然无存，因为她们每个人在其自己的沙龙中自视甚高而彼此孤立隔绝开来。
21. As my own studies have advanced，I have been increasingly impressed with the functional similarities between insect and vertebrate societies and less so with the structural differences that seem，at first glance，to constitute such an immense gulf between them. 随着我的研究不断深入，我对昆虫和脊椎动物群落之间的功能类似性印象愈来愈深刻，而对结构上的差异印象愈发淡漠，虽然这些结构上的差异初看上去似乎构成了二者间一条无法愈越的鸿沟。
22. Although fiction assuredly springs from political circumstances，its authors react to those circumstances in ways other than ideological，and talking about novels and stories primarily as instruments of ideology circumvents much of the fictional enterprise. 虽然小说无疑起源于政治情状，但其作者则是以非意识形态的方式对这些政治情状作出反应的，而将小说和故事主要地当作意识形态的工具来探讨，会在相当程度上阻碍小说事业。
23. Is this a defect，or are the authors working out of，or trying to forge，a different kind of aesthetic? 这究竟是一种缺陷呢，还是这些作者想要按照一种与众不同的美学体系进行创作，抑或是在试图创立一种与众不同的美学体系?
24. In addition, the style of some Black novels, like Jean Toomers Cane, verges on expressionism or surrealism ; does this technique provide a counterpoint to the prevalent theme that portrays the fate against which Black heroes are pitted , a theme usually conveyed by more naturalistic modes of expression ? 不仅如此，有些黑人小说的风格接近与表现主义和超现实主义;这种技巧是否为流行的主题提供了一个和谐的对应呢?这种主题刻画了黑人注意与之相抗争的命运，这是一个通常用更为自然主义的表现手法所表达的主题。
25. Black Fiction surveys a wide variety of novels，bringing to our attention in the process some fascinating and little-known works like James Weldon Johnsons Autobiography of an Ex-Colored Man. 《黑人小说》考察了极为广泛的一系列小说，在此过程中让我们注意到了某些引人入胜但却鲜为人知的作品，如詹姆斯。韦尔登。约翰逊的《一个曾经是有色人的自传》。
26. Although these molecules allow radiation at visible wavelengths， where most of the energy of sunlight is concentrated，to pass through，they absorb some of the longer-wavelength，infrared emissions radiated from the Earths surface，radiation that would otherwise be transmitted back into space. 虽然这些分子允许可见波长的辐射阳光的绝大部分能量就汇集于此不受阻挡地穿透，但它们却会吸收某些较长波长，亦即从地球表面辐射出的红外发射，这种辐射若不是二氧化碳的缘故就会被重新输送回太空。
27. The role those anthropologists ascribe to evolution is not of dictating the details of human behavior but one of imposing constraints-ways of feeling，thinking，and acting that come naturally in archetypal situations in any culture. 这些人类学家所归诸于生物进化的作用，不是规定人类行为的种种细节，而是将各种限制强加于人类即在任何文化的典型情景中都会自然表露的情感、思维、以及行动方式。
28. Which of the following most probably provides an appropriate analogy from human morphology for the details versus constraints distinction made in the passage in relation to human behavior? 以下哪一个选项最有可能为文章中所谈到的与人类行为有关的人类行为细节相对人类所受限制之间的差异，从人类形态的角度上提供了一个合适的类比?
29. A low number of algal cells in the presence of a high number of grazers suggested，but did not prove， that the grazers had removed most of the algae. 在存在大量食草动物的同时却只有少量的水藻花粉囊，这暗示出但没能证明食草动物已吞噬了大部分水藻。
30. Perhaps the fact many of these first studies considered only algae of a size that could be collected in a net , a practice that overlooked the smaller phytoplankton that we now know grazers are most likely to feed on , led to a de-emphasis of the role of grazers in subsequent research. 可能这样一个事实，那就是很多这样的最初的研究只是考虑了那些能够用网捞起来的大小的水藻，这样一个忽视了更小的浮游生物的做法，导致了在接下来的研究中对于捕食者的作用的贬低。
31. Studies by Hargrave and Geen estimated natural community grazing rates by measuring feeding rates of individual zooplankton species in the laboratory and then computing community grazing rates for field conditions using the known population density of grazers. 由哈格雷夫和吉恩所进行的研究，对自然条件下的群落捕食速率进行了估计，其手段是通过测量出实验室内单独的浮游动物种类的捕食速率，然后利用已知的食草动物种群密度，计算出实地状况下的群落捕食速率。
32. In the periods of peak zooplankton abundance，that is，in the late spring and in the summer， Haney recorded maximum daily community grazing rates，for nutrient-poor lakes and bog lakes，respectively，of 6.6 percent and 114 percent of daily phytoplankton production. 在浮游动物数量激增的高峰期，亦即在春季后期以及夏季，哈尼记录了最大程度上的每日群落食草比率，对于营养物不充足的湖和沼泽湖而言，分别为每日浮游植物繁殖量的6.6%和114%.
33. The hydrologic cycle，a major topic in this science，is the complete cycle of phenomena through which water passes，beginning as atmospheric water vapor，passing into liquid and solid form as precipitation，thence along and into the ground surface，and finally again returning to the form of atmospheric water vapor by means of evaporation and transpiration. 水文循环，作为该学科中的一个主要课题，指的是水所经过的诸现象的整个循环过程，开始时是作为大气中的水蒸气，转而作为雨、雪、露、雹一类的降水量经过液体和固体形态，由此而沿着地层表面分布或进入地层表面，最终通过蒸发和散发作用再度回复到大气水蒸气的形态。
34. Only when a system possesses natural or artificial boundaries that associate the water within it the hydrologic cycle may the entire system properly be termed hydrogeologic. 只有当一个系统拥有自然的或人工形成的边界来把边界中的水与水文循环联系起来的时候，才有可能把整个的系统恰当的成为与水文地质学有关。
35. The historian Frederick J. Turner wrote in the 1890s that the agrarian discontent that had been developing steadily in the United States since about 1870 had been precipitated by the closing of the internal frontierthat is，the depletion of available new land needed for further expansion of the American farming system. 史学家弗雷德里克.杰.特纳于十九世纪九十年代著述道，美国约自18世纪70年代以来一直在持续不断发展的农民不满，由于国内边远地区的封闭而更趋加剧亦即是说，美国农业系统进一步扩展所必需的可资利用的新土地几近耗竭。
36. In the early 1950s，historians who studied preindustrial Europe began， for the first time in large numbers，to investigate more of the preindustrial European population than the 2 or 3 percent who comprised the political and social elite：the kings，generals，judges，nobles，bishops，and local magnates who had hitherto usually filled history books. 二十世纪五十年代早期，研究前工业化时代欧洲的史学家，首次以众多的人数，开始调查前工业化时代欧洲人口中的大多数，而非那些构成了政治与社会精英阶层的百分之二或三的人口，即国王、将军、法官、贵族、主教、以及地方上的达官显贵，而正是这部分人一直到那时为止普遍充斥于史学著作。
37. Historians such as Le Roy Ladurie have used the documents to extract case histories， which have illuminated the attitudes of different social groups and have revealed how the authorities administered justice. 象勒罗伊。拉迪里一类的史学家利用这些文献史料从中挖掘出某些个案史来，阐明了不同社会群体的态度，并揭示出当局是如何执行审判的。
38. It can be inferred from the passage that a historian who wished to compare crime rates per thousand in a European city in one decade of the fifteenth century with crime rates in another decade of that century would probably be most aided by better information about which of the following? 从文章中可以推断出来，一个希望比较十五世纪以前一个十年的某个欧洲城市中的每千人的犯罪率与另外一个十年中的犯罪率的历史学家将会被以下那种信息的提高所最好的帮助?
39. My point is that its central consciousness-its profound understanding of class and gender as shaping influences on peoples lives-owes much to that earlier literary heritage，a heritage that，in general，has not been sufficiently valued by most contemporary literary critics. 我的论点是，其作品的中心意识它将阶级和性别作为人们生活的决定性影响而作出的深邃理解在很大程度上借鉴了那个早期的文学遗产，而这一遗产就总体而言还尚未获得大多数当代文学评论家的足够重视。
40. Even the requirement that biomaterials processed from these materials be nontoxic to host tissue can be met by techniques derived from studying the reactions of tissue cultures to biomaterials or from short-term implants. 即使是这样的要求，即从这些材料中加工出来的生物材料应该对受移植者的组织无害，也能够通过从研究组织培养对生物材料的反应而来的，或从研究短期移植而来的技术来满足。
41. But achieving necessary matches in physical properties across interfaces between living and nonliving matter requires knowledge of which molecules control the bonding of cells to each other-an area that we have not yet explored thoroughly. 但是，要想沿着原生和非原生物质之间的界面获取生理特性的必要匹配，需要某种知识，即什么样的分子控制着细胞彼此间的结合而对这一领域，我们尚未进行充分的探索。
42. Islamic law is a phenomenon so different from all other forms of law-notwithstanding，of course，a considerable and inevitable number of coincidences with one or the other of them as far as subject matter and positive enactments are concerned-that its study is indispensable in order to appreciate adequately the full range of possible legal phenomena. 伊斯兰法是一种如此不同于所有其它法律形式的现象毋庸置疑，尽管就其主要内容和有积极意义的法规而言，与其它法律形式中的这种或那种形式存在着相当数量的且不可避免的巧合相似之处以致于对它进行研究便显得不可或缺，以便充分理解有可能存在的法律现象的全部范围。
43. Though historically there is a discernible break between Jewish law of the sovereign state of ancient Israel and of the Diaspora ， the spirit of the legal matter in later parts of the Old Testament is very close to that of the Talmud， one of the primary codifications of Jewish law in the Diaspora. 尽管从历史角度来看，在古代以色列作为独立主权国家的犹太教法与大流散时期的犹太教法之间存在着一个明晰可辨的断裂，然则，《旧约全书》后半部分中法律内容的精神与《犹太教法典》极为一脉相承，而所谓的《犹太教法典》，是指大流散时期犹太教法的主要典籍辑录之一。
44. Islam，on the other hand，represented a radical breakaway from the Arab paganism that preceded it;Islamic law is the result of an examination, from a religious angle，of legal subject matter that was far from uniform，comprising as it did the various components of the laws of pre-Islamic Arabia and numerous legal elements taken over from the non-Arab peoples of the conquered territories. 另一方面，伊斯兰教则代表着与此前存在的阿拉伯异教的一种根本上的决裂;伊斯兰法是从宗教的角度，对各种杂乱无章、绝无共同点的法律内容进行考察所致的结果，而这些法律内容实际上是由前伊斯兰阿拉伯国家法律的不尽相同的组成部分以及由从被征服的土地上非阿拉伯民族借鉴过来的无数法律因素所构成。 实际上是一句插入语。
45. One such novel idea is that of inserting into the chromosomes of plants discrete genes that are not a part of the plants natural constitution：specifically，the idea of inserting into nonleguminous plants the genes，if they can be identified and isolated，that fit the leguminous plants to be hosts for nitrogen-fixing bacteria. Hence， the intensified research on legumes. 这其中的一个新颖思想就是，在植物的染色体内注入并非是该植物自然构造一个部分的那些不相关联的因基：具体而言，这一思想是，在非豆科植物内注入这样一些基因，倘若这些基因可被辨识出来并被分离开来，而这些基因业已使豆科植物宜于充当那些具备固氮作用的细菌的寄主。由此，对豆科植物的研究日趋深入。
46. It is one of natures great ironies that the availability of nitrogen in the soil frequently sets an upper limit on plant growth even though the plants leaves are bathed in a sea of nitrogen gas. 下述情形真可谓是自然界的一个莫大讽刺：土壤中所能获得的氮肥量往往对植物的生长构成了一个上限，虽然植物的叶子被沐浴在一片氮气的海洋中。
47. Unless they succeed，the yield gains of the Green Revolution will be largely lost even if the genes in legumes that equip those plants to enter into a symbiosis with nitrogen fixers are identified and isolated，and even if the transfer of those gene complexes，once they are found， becomes possible. 除非他们能取得成功，不然的话，绿色革命的产量收益将在很大程度上损失殆尽，即使豆科植物中使这些植物有条件进入到与固氮细菌共生关系的基因可被辨识出来和分离开来的话，且即使这些基因综合体，一旦被发现之后，其移植得以成为可能的话。
48. Its subjectis life-as-spectacle， for readers, diverted by its various incidents，observe its hero Odysseus primarily from without;the tragic Iliad，however，presents life-as-experience：readers are asked to identify with the mind of Achilles，whose motivations render him a not particularly likable hero. 其主题〔若借鉴梅纳德。迈克的两个分类范畴的话〕是人生作为外部景象，因为读者的注意力被作品那形形色色的事件所分散，主要是从外部来观察其主人公奥德修斯的;然而，富于悲剧色彩的《伊利亚特》所表现的则是人生作为内心体验：读者被要求与阿基琉斯的心灵产生共鸣，而其行为动机却致使他变作一个并非特别惹人喜爱的主人公。 注：hero:主人公;without:外部;likable:有吸引力的
49. Most striking among the many asymmetries evident in an adult flatfish is eye placement： before maturity one eye migrates，so that in an adult flatfish both eyes are on the same side of the head. 在一条成年比目鱼身上显著存在的诸多不对称特征中，最为吸人注目的是眼睛的摆位：在成年之前，一只眼睛发生移动，因此在成年比目鱼身上，两只眼睛均位于头部的同一侧面。
50. A critique of Handlins interpretation of why legal slavery did not appear until the 1660s suggests that assumptions about the relation between slavery and racial prejudice should be reexamined , and that explanations for the different treatment of Black slaves in North and South America should be expanded . 一个对于H的关于为何法律上的奴隶制没有在17世纪60年代以前出现的原因所作解释的批评显示，关于奴隶制和种族偏见之间的关系的假说应当重新检查，而且显示出，对于在北美和南美之间的对黑怒的不同处理的解释应当被扩展。
51. The best evidence for the layered-mantle thesis is the well-established fact that volcanic rocks found on oceanic islands，islands believed to result from mantle plumes arising from the lower mantle，are composed of material fundamentally different from that of the mid-ocean ridge system， whose source，most geologists contend，is the upper mantle. 对于地幔分层论点来说，最好的证据乃这样一个确认的事实，即在那些海洋岛屿这些岛屿据信是源于由下层地幔升上来的地幔柱状溶岩流上发现的火山岩石，是由与海洋中部山脊系统的物质根本不同的物质构成的，而这一海洋中部山脊系统的成因，大多数地质学家论辩道，为上部地幔。
52. Some geologists，however，on the basis of observations concerning mantle xenoliths， argue that the mantle is not layered，but that heterogeneity is created by fluids rich in incompatible elements percolating upward and transforming portions of the upper mantle irregularly，according to the vagaries of the fluids pathways. 但是，某些地质学家，以对地幔捕虏岩体所作的观察为依据，指出地幔并非是分层排列的，相反，地幔的异质性是由那些富含不相容成分的流质构成的，这些成分趋向于流体而非固体的状态，自下而上渗透扩散，并依照这些流质流向的任意性，不规则地将上部地幔的某些部分予以改变。
53. Fallois proposed that Proust had tried to begin a novel in 1908, abandoned it for what was to be a long demonstration of Saint-Beuves blindness to the real nature of great writing , found the essay giving rise to personal memories and fictional developments ,and allowed these to take over it a steadily developing novel. F认为，P在1908年试图开始写一部小说，又为了写一部批判S-B的 伟大作品的真正本质的视而不见的长篇的证明而放弃了这部小说，其后又发现这一论文又勾起了其个人记忆及小说情节的萌生，使得后者取而代之形成了一部稳定展开的小说。
54. The very richness and complexity of the meaningful relationships that kept presenting and rearranging themselves on all levels，from abstract intelligence to profound dreamy feelings， made it difficult for Proust to set them out coherently. 各种有意义的联系在所有的层次上，自抽象的理性至深刻的梦幻般的情感，层出不穷并不断重新组合排列;正是这些有意义的联系的丰富性和复杂性，致使普鲁斯特难于将它们错落有致地安排好。
55. But those of who hoped, with Kolb, that Kolbs newly published complete edition of Prousts correspondence for 1909 would document the process in greater detail are disappointed. 但是我们当中的那些希望K新出版的P1909年书信的全集能够更加详细的记录下这一过程的人都大失所望。
56. Now we must also examine the culture as we Mexican Americans have experienced it , passing from a sovereign people to compatriots with newly arriving settlers to , finally ，a conquered people - a charter minority on our own land. 现在我们必须也按照我们墨西哥裔的美国人的经历来审视这个文化，我们的经历是从一个主权的民族变成了新来的定居者的同胞，在最终沦落成为一个被征服的民族在我们自己的土地上的契约的少数民族。
57. It is possible to make specific complementary DNAs that can serve as molecular probes to seek out the messenger RNAs of the peptide hormones. If brain cells are making the hormones，the cells will contain these MrnaS. If the products the brain cells make resemble the hormones but are not identical to them，then the cDNAs should still bind to these mRNAs，but should not bind as tightly as they would to mRNAs for the true hormones. 科学家可以制造出特异的互补DNAs，以此作为分子探子，探觅出肽激素的信使RNAs。如果大脑正在制造着肽激素，则细胞就会含有这些信使RNAs.假若细胞所制造的产品类似于肽激素但并非与这些肽激素全然相同，那么，互补cDNAs应仍然和这些信使mDNAs粘结的程度。含有这些mRNAs的脑细胞然后就可以被分离开来，研究者可对其信使RNAs进行解码，以确定它们的蛋白质产品究竟是什么，并确定这些蛋白质产品在何种程度上类似于真正的肽激素。
58. The molecular approach to detecting peptide hormones using cDNA probes should also be much faster than the immunological method because it can take years of tedious purifications to isolate peptide hormones and then develop antiserums to them. 采用cDNA探子来测定肽激素的这一分子生物学方法同时也应该比免疫学的方法速度来得快，因为对于免疫的方法来说，需耗费好几年枯燥的提纯进程，方能将肽素分离了出来，然后再培养出针对它们的抗血清。
59. Nevertheless, researchers of the Pleistocene epoch have developed all sorts of more or less fanciful model schemes of how they would have arranged the Ice Age had they been in charge of events. 然而，研究P时代的研究者发展除了各种各样的或多或少有些奇怪思想的模型系统，用来显示如果由他们来决定地质事件的话他们将会如何安排冰川纪。
60. This succession was based primarily on a series of deposits and events not directly related to glacial and interglacial periods，rather than on the more usual modern method of studying biological remains found in interglacial beds themselves interstratified within glacial deposits. 这一序列演替所依据的，主要是一系列与冰川期和间冰期并不直接相关的地质沉积物和地质事件，而不是依据更为普遍的现代方法，去研究间冰层中所发现的生物残留物，而这些间冰层本身又在冰川沉积物发生间层化。
61. There have been attempts to explain these taboos in terms of inappropriate social relationships either between those who are involved and those who are not simultaneously involved in the satisfaction of a bodily need，or between those already satiated and those who appear to be shamelessly gorging. 人们试图对这些禁忌作出解释，所依据的要么是那些正置身于某一身体需要满足的人与那些并置身于某一身体需要之满足的人之间的，要么是那些早已酒足饭饱的人与那些正在不知羞耻地狼吞虎咽失之间的不相称的社会关系。
62. Many critics of Family Brontes novel Wuthering Heights see its second part as a counterpoint that comments on，if it does not reverse，the first part，where a romantic reading receives more confirmation. 研究艾米丽。勃朗特小说《呼啸山庄》的许多文学评论家，将小说的第二部分视作一种对比物，即使没有将第一部分予以逆转的话，也是在对第一部分作出一种诠释评判，而在小说第一部分中，一种浪漫的的读解能获得更为充分的确证。
63. Granted that the presence of these elements need not argue an authorial awareness of novelistic construction comparable to that of Henry James， their presence does encourage attempts to unify the novels heterogeneous parts. 诚然，这些因素的存在并不能证明作者对小说架构的意识可与亨利。詹姆斯的那种意识相比拟;然则，任何力图将小说所有形形色色的因素统一起来的做法，在某种程度上注定是无法令人信服的。 Granted that:大家都统一、当然，表让步，=admitted , of course.
64. This is not because such an interpretation necessarily stiffens into a thesis，but because Wuthering Heights has recalcitrant elements of undeniable power that，ultimately，resist inclusion in an all-encompassing interpretation. 这倒不是因为这样的一种解释必定会僵化成为一个命题，而是因为《呼啸山庄》拥有一些极难驾御的因素，以其无可辩驳的力度，最终拒绝被囿于一个囊括无遗的解释中。
65. The isotopic composition of lead often varies from one source of common copper ore to another，with variations exceeding the measurement error;and preliminary studies indicate virtually uniform is topic composition of the lead from a single copper-ore source. 铅的同位素构成经常在一种普通铜矿石来源与另一种铜矿石来源之间存在差异，其差异程度超出测量误差;而最初的研究表明，对于来自单独一个铜矿石来源的铅来说，其同位素构成几乎是毫无二致的。
66. More probable is bird transport，either externally，by accidental attachment of the seeds to feathers，or internally，by the swallowing of fruit and subsequent excretion of the seeds. 更有可能的是鸟类运输：或者是通过外部途径，即由于种籽偶然粘附在羽毛上;或者是通过内部方式，即由于鸟类吞食果子并随后将种籽排泄出来。
67. A long-held view of the history of English colonies that became the United States has been that Englands policy toward these colonies before 1763 was dictated by commercial interests and that a change to a more imperial policy , dominated by expansionist militarist objectives , generated the tensions that ultimately led to the American Revolution . 一个对于后来成了美国的英国殖民地的历史的长久以来的观点，认为英国在1763年以前对于这些殖民地的政策被经济利益所支配，而且认为一种向着更大程度帝国制度的政策上的转变为扩张主义的军事目标所左右产生了最终导致美国革命的紧张气氛。
68. It is not known how rare this resemblance is，or whether it is most often seen in inclusions of silicates such as garnet，whose crystallography is generally somewhat similar to that of diamond; but when present，the resemblance is regarded as compelling evidence that the diamonds and inclusions are truly cogenetic. 现在尚不知这种类似稀少到何种地步，也不知道是否它最常见于象石榴石一类的硅酸盐内含物中，而这类物质的晶体结构普遍地在某种程度上类似于金刚石的晶体结构。但一旦存在，这种类似就被视作极有说服力的证据，证明金刚石与内含物确是同源的。
69. Even the radical critiques of this mainstream research model，such as the critique developed in Divided Society，attach the issue of ethnic assimilation too mechanically to factors of economic and social mobility and are thus unable to illuminate the cultural subordination of Puerto Ricans as a colonial minority. 即使是对这一主流研究模型的激进批评，诸如《分裂的社会》一书中所提出的那种批判，亦将少数民族同化问题过分机构地与经济和社会移动性的因素联系起来，因此无从阐明波多黎各人作为一个殖民地少数民族的文化从属关系。
70. They are called virtual particles in order to distinguish them from real particles，whose lifetimes are not constrained in the same way，and which can be detected. 它们被称为虚粒子，以便与实粒子区分开来，而实粒子则不会以这种方式受到制约，并且其存在可得以测定。
71. Open acknowledgement of the existence of womens oppression was too radical for the United Stated in the fifties, and Beauvoirs conclusion, that change in womens economic condition , though insufficient by itself , remains the basic factor in improving womens situation , was particularly unacceptable . 公开对妇女压迫的存在的承认对于50年代的美国而言有些过分激进，而且B的结论，即妇女经济状况的变化，经管它本身不是一个充分的因素，但是仍然是提高妇女地位的根本因素的观点，尤其无法令人接受。
72. Other theorists propose that the Moon was ripped out of the Earths rocky mantle by the Earths collision with another large celestial body after much of the Earths iron fell to its core. 其他的理论家提出，在地球的大部分铁沉入到地核之后，由于地球与另一个庞大的天体发生碰撞，月亮便从地球那石质的地幔中撕裂开来而形成的。 Rip:撕开;拨去;在本文是撕开的意思。
73. However, recent scholarship has strongly suggested that those aspects of early New England culture that seem to have been most distinctly Puritan, such as the strong religious orientation and the communal impulse, were not even typical of New England as a whole, but were largely confined to the two colonies of Massachusetts and Connecticut. 然而，进来的学术研究强烈的显示那些看来最为明确的请教徒的早期新英格兰文化的一些方面，比如强烈的宗教导向和团体意识，就整体而言却不是新英格兰的典型特征，而是在很大程度上只局限与马萨诸赛和康涅狄格两个州。
74. Thus，what in contrast to the Puritan colonies appears to Davis to be peculiarly Southern- acquisitiveness，a strong interest in politics and the law，and a tendency to cultivate metropolitan cultural models-was not only more typically English than the cultural patterns exhibited by Puritan Massachusetts and Connecticut，but also almost certainly characteristic of most other early modern British colonies from Barbados north to Rhode Island and New Hampshire. 因此，那些与清教殖民地形成鲜明对比、并在戴维斯教授的心目中显得具有特殊南方色彩的特征占有欲、对政治和法律的浓厚兴趣、以及培养大都市文化模式的倾向不仅仅要比清教的马萨诸塞州和康乃涅克州所展现出来的文化模式更具有典型的英国色彩，并且几乎毫无疑问地构成了绝大多数其它早期近代英国殖民地的特征，从巴巴多斯北至罗得岛和新罕布什尔州。
75. Portrayals of the folk of Mecklenburg County, North Carolina, whom he remembers from early childhood, of the jazz musicians and tenement roofs of his Harlem days, of Pittsburgh steelworkers, and his reconstruction of classical Greek myths in the guise of the ancient Black kingdom of Benin, attest to this. 一些描述，关于他从小就记得的北卡罗来纳州的M县的人民、关于他在H的日子里的爵士乐手和公寓的房顶、关于匹兹堡的钢铁工人的描述和他的假借古代B国对古希腊神话得宠俗，都表现了这一点。In the guise of :假借、在的幌子下，假装.
76. A very specialized feeding adaptation in zooplankton is that of the tadpolelike appendicularian who lives in a walnut-sized balloon of mucus equipped with filters that capture and concentrate phytoplankton. 浮游动物体内一种极特殊的进食适应性变化是蝌蚪状的尾海鞘纲动物的那种适应性变化，而尾海鞘纲动物则存活于核桃大小的黏液球囊内，装备有过滤器，用以捕捉和集中浮游植物。
77. These historians，however，have analyzed less fully the development of specifically feminist ideas and activities during the same period. 但是，这些史学家还不曾充分地分析同一时期中那些具体的女权主义思想和活动的发展。
78. Apparently most massive stars manage to lose sufficient material that their masses drop below the critical value of 1.4 M before they exhaust their nuclear fuel. 显然，大多数的巨星能够失去足够多的物质以至于在燃尽其核燃料以前他们的质量下降到关键值1.4M以下。难在：sufficient that = so much that
79. This is so even though armed forces operate in an ethos of institutional change oriented toward occupational equality and under the federal sanction of equal pay for equal work. 即使是武装部队是在一种趋向职业平等的制度变迁的风气中运作的时候，而且即使部队是在联邦政府的同工同酬的约束下运行的时候，情况仍然是这样。
80. An impact capable of ejecting a fragment of the Martian surface into an Earth-intersecting orbit is even less probable than such an event on the Moon, in view of the Moons smaller size and closer proximity to Earth. 一个能够把活性表面的碎片射入地球交叉轨道的碰撞发生的可能性甚至小于这种事件在月亮上发生的可能性，考虑到月亮更小的尺寸及其与地球接近的程度。
81. Not only are liver transplants never rejected，but they even induce a state of donor-specific unresponsiveness in which subsequent transplants of other organs, such as skin,from that donor are accepted permanently. 但是，我们已经发现，在许多种老鼠之间，这些移植法的常规并没有被肝脏移植物所遵循。肝脏移植物非但从没遭到过排斥，甚至还诱发了一种供者特异性无应答状态，在此状态中，随后来自那个供者其它器官的移植物，如皮肤，会永久地被接受。
82. As rock interface are crossed, the elastic characteristics encountered generally change abruptly, which causes part of the energy to be reflected back to the surface, where it is recorded by seismic instruments. 当岩石界面被穿过的时候，震波所遇到的弹性性质通常会发生突然的变化，这就使得一部分能量被反射回地面，在地面反射回来的波被震波纪录仪记录下来。
83. While the new doctrine seems almost certainly correct，the one papyrus fragment raises the specter that another may be unearthed，showing，for instance，that it was a posthumous production of the Danaid tetralogy which bested Sophocles,and throwing the date once more into utter confusion. 数据资料已被统计出来，或被重新统计出来，以便证明在文体学这方面，《乞援衰女》实际上确实在《波斯人》和《七雄攻忒拜》之后以及在轴残片却唤起了一种幽灵似的疑虑，即另一块残片有可能再度被挖掘出来，并证明，比如说，《乞援衰女》是作者藉以击败索福克勒斯的《达那特四部曲》的一部死后出版之作，从而将创作年代再度置于极度的混乱之中. 注：best:击败,=defeat, overcome, outdo
84. The methods that a community devises to perpetuate itself come into being to preserve aspects of the cultural legacy that that community perceives as essential. 一个社会所创造出来藉以使其自身生生不息、恒久不衰的方法得以形成产生，以保存在这个社会看来具有本质意义的文化遗产的各个方面。
85. Traditionally, pollination by wind has been viewed as a reproductive process marked by random events in which the vagaries of the wind are compensated for by the generation of vast quantities of pollen, so that the ultimate production of new seeds is assured at the expense of producing much more pollen than is actually used. 传统上，风媒传粉被看成是这样的繁殖过程：其特征就是由一些随即事件的发生，在这些随机事件里，风的反复无常被大量的产生花粉所补偿，以至于新种子的最终产生被保证了，其代价是产生远远多于实际使用量的花粉。
86. Because the potential hazards pollen grains are subject to as they are transported over long distances are enormous，wind pollinated plants have，in the view above，compensated for the ensuing loss of pollen through happenstance by virtue of producing an amount of pollen that is one to three orders of magnitude greater than the amount produced by species pollinated by insects. 由于花粉粒在其长距离的运输过程中所要面临的潜在危险是巨大的，按上述观点来看，由风授粉的植物补偿了通过偶发事件而伴随造成的花粉损失。其途径是，制造出大于昆虫授粉的植物种类所产生的花粉量的一至三个数量级的花粉量。
87. For example，the spiral arrangement of scale-bract complexes on ovule-bearing pine cones，where the female reproductive organs of conifers are located，is important to the production of airflow patterns that spiral over the cones surfaces，thereby passing airborne pollen from one scale to the next. 例如，带有胚珠的松球的鳞苞综合体的螺旋状安排，亦即松柏目植物雌性殖器官的所在位置，对于气流模式的形成与产生殊为重要，而这些气流模式在松球的表现盘旋上升，从而把在空气中飞行的花粉从一个鳞苞传播至下一个鳞苞。
88. Friedrich Engels, however, predicted that women would be liberated from the social, legal, and economic subordination of the family by technological developments that made possible the recruitment of the whole female sex into public industry. FE,却预测妇女们将被从家庭的社会、法律和经济压迫中解放出来，只是通过使得征召整个女性阶层进入公共的工业中去成为可能的技术进步的方式做到的。
89. It was not the change in office technology,but rather the separation of secretarial work,previously seen as an apprenticeship for beginning managers，from administrative work that in the 1880s created a new class of dead-end jobs，thenceforth considered womens work. 十九世纪八十年代，产生了新的一类没前途的职业，这并不是因为办公室技术发生了改变，而是由于秘书工作在此之前被视作是初起步的经理们的一种习见训练与行政工作的分离。自此以后，这类没前途的职业便被视作是女人的工作。
90. The increase in the numbers of married women employed outside the home in the twentieth century had less to do with the mechanization of housework and an increase in leisure time for these women than it did with their own economic necessity and with high marriage rates that shrank the available pool of single women workers, previously, in many cases, the only women employers would hire. 二十世纪已婚妇女在家庭以外就业的人数不断增加，这与家务的机械化及这些妇女闲暇时间的增加并无多大联系，更多地是与妇女自身的经济需要和高婚姻率相关。高婚姻率致使所能雇佣的单身女工的总量缩减，而在此之前的许多情形中，单身女性则是雇主们所愿雇佣的唯一-一类妇女。 The pool of 如果后面跟着一群人，则表示劳动力资源。
91. For one thing, no population can be driven entirely by density-independent factors all the time. 请思考:如果文中说这句话的前提是：all population are driven by two categories of growth parameters, one is density-independent factors, and the other is density-independent factors. 那么作者说上面的这句话有什么用意。解释：本句虽然貌不惊人，但本书既然将其收录进来，并标出难度5，就意味着其中有怪异之处。值得一提的是，本文前面曾把控制种群密度的因素分为两种，一种叫做density-dependent factors，另一种叫做dentsity-independent factors。原文的直译虽然好懂，但是总令人感觉说得不甚明白。显然，GRE或GMAT的作者不可能随便说一句无关痛痒的话，那么没有任何种群能够在所有的时间全被d-I因素所控制，其真正意思是什么呢?就是：一切种群都必然在某个时间内受到d-d因素的控制。本句是ETS在考试中惯用的正话反说的典型例子，请读者深沉体会。本句在文章中也是理解作者态度的关键所在。
92. In order to understand the nature of the ecologists investigation，we may think of the density-dependent effects on growth parameters as the signal ecologists are trying to isolate and interpret，one that tends to make the population increase from relatively low values or decrease from relatively high ones，while the density-independent effects act to produce noise in the population dynamics. 为了能理解生态学家们所从事的研究的性质，我们可以把那些作用于增长参数的密度依赖效应视作生态学家们力图将其分离并予以解释的信号，正是这一信号倾向于使种群从相对较低的数值递增，或从相对较高的数值递减;而与此同时，那些密度独立效应起到的作用则构成了种群动态变化中的噪音.
93. But the plays complex view of Black self-esteem and human solidarity as compatible is no more contradictory than Du Bois famous，well-considered ideal of ethnic self-awareness coexisting with human unity，or Fanons emphasis on an ideal internationalism that also accommodates national identities and roles. 但该剧有关黑人自尊可与人类团结相融合这一复杂观点，丝毫都不比杜波伊斯的理想或法侬的强调来得更为矛盾：杜波伊斯提出的著名的、深思熟虑的理想是，民族的自觉可以和人类大同共存;法侬则对理想的国际主义进行了强调，而这一理想的国际主义同样也能兼容民族身份与角色。
94. In which of the following does the author of the passage reinforce his criticism of responses such as Isaacs to Raisin in the Sun? 在以下哪一个选项中，文章的作者加强了她对类似这样的对于《》做出的反应的批判呢?
95. Inheritors of some of the viewpoints of early twentieth-century Progressive historians such as Beard and Becker，these recent historians have put forward arguments that deserve evaluation. 作为二十世纪早期进步派史学家等人某些观点的继承者，这些近期的史学家所提出的观点值得我们予以评价。
96. Despite these vague categories，one should not claim unequivocally that hostility between recognizable classes cannot be legitimately observed. 尽管存在这些模糊范畴，但我们不应该断然声称，在各个易于辨认出的阶层之间所存在的敌对态度就无法被合理地观察到。
97. Yet those who stress the achievement of a general consensus among the colonists cannot fully understand that consensus without understanding the conflicts that had to be overcome or repressed in order to reach it. 然而，有些史学家强调在殖民者之间曾出现过一种普遍的一致意见。这些史学家如果不认识到各种矛盾的存在，就无法充分地理解这种一致意见，而所有那些矛盾只有在被克服或压制之后才有可能获得那种一致意见。 It 指代：general consensus
98. It can be inferred from the passage that the author would be most likely to agree with which of the following statements regarding socioeconomic class and support for the rebel and Loyalist causes during the American Revolutionary War? 从文章中可以推断出来，作者最有可能同意以下哪一个关于在美国革命战争中的社会经济各阶层及其对叛党和保王党的支持的陈述?
99. She wished to discard the traditional methods and established vocabularies of such dance forms as ballet and to explore the internal sources of human expressiveness. 她希望抛弃传统的方法和像芭蕾舞这样已经确立的舞蹈语言，而希望探索人类表现力的内在源泉。
100. Although it has been possible to infer from the goods and services actually produced what manufactures and servicing trades thought their customers wanted，only a study of relevant personal documents written by actual consumers will provide a precise picture of who wanted what. 尽管有可能从实际制造的商品和服务中可推知制造商和服务业认为他们的顾客所需要的是什么，但只有对由实际顾客撰写的相关的个人文件进行一番研究，方能提供一幅精确的图画，藉以说明什么样的人需要什么样的东西。
