GRE NO题难句摘录及分析
1.That sex ratio will be favored which maximizes the number ofdescendants 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。
2.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。
3.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 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。
4.Although Gutman admits that forced separation by sale was frequent,he shows that the slavespreference,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。
5.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 andd 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。
6.This preference for exogamy,Gutman suggests,may have derived fromWest 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。
8. 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.
9.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。 Other experiments revealed slight variations in the size,number,arrangement,and interconnection of the nerve cells,but as far as psychoneural correlations were concerned,the obvious similarities of these sensory fields to each other seemed much more remarkable than any of the minute differences。 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。
10.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。
GRE NO题难句摘录及分析
11.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。
12.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。
13.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。
14.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。
15. 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。

16.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,或者是否表明,这些作者是在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?
17.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。

由哈格雷夫和吉恩所进行的研究,对自然条件下的群落食草比例进行了估计,其手段是通过测量出实验室内单独的浮游动物种类的结食比例,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食草比例。
22.In the periods of peak zooplankton abundance,that is,in the late spring and in the summer,Haney recorded maximum daily com-munity 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%。
23.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。
24.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 frontiers,historians who studied preindustrial Europe began,for the first time in large numbers,to investigate more of the preindustrial European population than the 2or3 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。

26.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。

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。
28.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 othernatural 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。
33.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 plantsleaves 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。
