03. Hardy's weakness derived from his apparent inability to control the comings and goings of the divergent impuls 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。
读书札记04. Virginia Woolf's 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（Virginia Woolf）在创作《黛洛维夫人》（Mrs. Dalloway）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（poetic novelist）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 t upon another becau 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"

07. Although Gutman admits that forced paration 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（monogamy）。
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 clo 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（union with clo kin）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-bad 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 Chine 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 impul or its condition was influenced by the differences , which emed 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 impuls are esntially 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 the nsory fields to each other emed much more remar
kable than any of the minute differences. 尽管其他实验显示在神经细胞的大小、数量、
茉莉的花语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 reprentation becomes more holistic and the recognition process correspondingly more parallel，the weight of evidence ems to support the rial 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（rial hypothesis），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 conquence of the feminist movement，historians have focud a great deal of attention in recent years on determining more accurately the status of women in
自然特征various periods. 在很大程度上，由于女权主义运动（feminist movement）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 reprent obrved historical fact -real Amazonian societies - but rather to offer "moral lessons" on the suppod outcome of women's 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 itlf only an imperfect approximation to an infinite t 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（Schrodinger）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 preci argument，since an argument that is convincing only if it is preci los all its force if the assumptions on which it is bad are slightly
changed，whereas an argument that is convincing though impreci 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（underlying assumption）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 themlves as a women's group and to posss a n 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 impresd with the functional similarities between inct and vertebrate societies and less so with the structural differences that
em，at first glance，to constitute such an immen 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 tho circumstances in ways other than ideological，and talking about novels and stories primarily as instruments of ideology circumvents much of the fictional enterpri. 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。花寓意
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？审计范围
24. In addition, the style of some Black novels, like Jean Toomer's 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（比如JT的甘蔗）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 Johnson's 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（James Weldon Johnson）的《一个曾经是有色人的自传》（Autobiography of an Ex-Colored Man）。

26. Although the 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 Earth's surface，radiation that would otherwi be transmitted back into space. 虽然这些分子允许可见波长（visible wavelength）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（longer-wavelength），亦即从地球表面辐射出的红外发射（infrared emission），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 tho anthropologists ascribe to evolution is not of dictating the details of human behavi
or 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？
