1、1. However, none of these high-technology methods are of any value if the sites to which they are applied have never mineralized, and to maximize the chances of discovery the explorer must therefore pay particular attention to selecting the ground formations most likely to be mineralized.但是，如果这些方法所应
2、用的地点没有被矿化的话那么这些高科技方法就毫无价值。因此，探索者为了最大化发现矿产的机会，必须对选择最有可能被矿化的地质构成给予特别的关注。2. Rather，the coincidence of increased United States government antidiscrimination pressure in the mid-1960s with the acceleration in the rate of black economic progress beginning in 1965 argues against the community theorists vie
3、w.20世纪60年代中期，美国政府反对歧视的压力不断升高，与此同时，从1965年开始，黑人经济状况改善的步伐越来越快。确切的说，这两个事件的同时发生违背了连续性理论家的观点。3.

4、land of opportunity.虽然起初对于英国人来说没有什么正面的吸引力，他们宁愿呆在家里，但是到了18世纪的时候，越来越多的人移民到美国，因为他们将美国视为一片充满机会的土地。4. Although surveys of medieval legislation, guild organization, and terminology used to designate different medical practitioners have demonstrated that numerous medical specialties were recognized in Euro
5、pe during the Middle Ages, most historians continue to equate the term “women medical practitioner”, wherever they encounter it in medieval records, with “midwife”.虽然关于中世纪的立法、行会组织和用于命名不同医术人员的术语做了许多调查，而且这些调查证明了中世纪欧洲的许多医学专家都被正式认可，但是大部分历史学家只要在中世纪文献中遇到“女性医护人员”这个术语时，还是会把这个术语等同于“接生婆”。5. One might conclude
6、 that the older labor-intensive machinery still operating in United States integrated plants is at fault for the poor performance of the United States industry, but this cannot explain why Japanese integrated producers, who produce a higher-quality product using less energy and labor, are also exper
7、iencing economic trouble.或许有人会总结道，老式的、密集劳动型的机制依旧在美国的大型工厂中运作，正是这些机制应该为美国工业不尽人意的表现负责，但是这并不能解释为什么即使日本的一体化生产商可以利用更少的资源与劳力生产出更高质量的产品，但他们也依旧处于经济困难的状态。6. Moreover，the almost simultaneous abolition of Russian serfdom and United States slavery in the 1960sa riveting coincidence that should have drawn more mo
8、dern scholars to a comparative study of the two systems of servitudehas failed to arouse the interest of scholars.更为甚者，俄国农奴制与美国农奴制在19世纪60年代同时被废除。这个巧合非常有意思，现代学者本应对这两个奴役体系进行比较研究，但是这一巧合并没有引起学者的兴趣。7. Thomas V Carroll has proposed that the conclusions drawn by previous researchers are attributable to the
9、ir myopic focus on the premise that, unless right-to-work laws significantly reduce union membership within a state, they have no effect.Thomas V Carroll认为，先前研究者缺乏远见，认为除非各种禁止公会存在的法律大幅减少某个州的公会人数，否则这些法律无效。在这种前提下，先前研究者得出了这些结论。8. The Constitution gives Congress the basic power to declare war, as well as
10、 the authority to raise and support armies and a navy, enact regulations for the control of the military, and provide for the common defense.宪法赋予议会宣战的基本权利，同时还有招募及供养陆军和海军、管理军队的支配和提供共同防御的权利。9. One argument against my contention asserts that, by nature, text books are culturally biased and one argument
11、 against my contention asserts that I am simply underestimating childrens ability to see through these biases.一个与我的观点相对立的观点认为教科书本质上都存在文化偏见，而且认为我低估了小孩看穿这些偏见的能力。10. Competing for votes, parties seek to offer different sections of the electorate what they most want; they do not ask what the majority th
12、inks of an issue, but what policy commitments will sway the electoral decisions of particular groups.为了尽可能多的获得选票，政党尝试着给不同的选民许诺他们最想获得的东西；这些政党并不考虑大部分选民对某个议题的看法，而是考虑什么样的政策许诺能够改变某些特定群体的投票决定。11. He insisted that there could be no return to traditional, preindustrial; only by accepting wholeheartedly the
13、political and technological revolutions of the nineteenth century could the architect establish the forms appropriate to a modern, urban society.他坚持认为不可能再回到传统的、前工业化时代的模式；只有全心全意的去接受19世纪的政治和科技革命，建筑师才能建立起适合现代都市社会的模式。12. This preference for exogamy, Gutman suggests, may have derived from West African ru
14、les governing marriage, which , though they differed from one tribal group to another, all involved some kind of prohibition against unions with close kin.Gutman认为，这种与外族通婚的偏好源自于西非地区在婚姻方面的规定，虽然这类规定在每一个部落都不尽相同，但是所有这些规定都禁止近亲结婚。13. Such variations in size, shape, chemistry, conduction speed, excitation
15、threshold, and the like as had been demonstrated in nerve cells remained negligible in significance in any possible correlation with the manifold dimensions of mental experience.神经细胞在大小、形状、化学性质、传导速度、兴奋阀值及其他类似方面存在差异。当这些差异与心理体验的诸多方面以可能的方式联系起来时，其重要性仍然微不足道。14. Although qualitative variance among nerve e
16、nergies was never rigidly disapproved, the doctrine was generally abandoned in favor of the opposing view, namely, that nerve impulses are essentially homogeneous in quality and nerve impulses are transmitted as “common currency” throughout the nerve system.虽然在神经能量方面存在着质的差异这一点从未被严格证伪过，但是人们往往会抛弃这个传统的
17、教条而支持它的对立面，即：神经冲动从根本上性质相同，而且它们以“通货”的形式在神经系统中传递。15. 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 based in a sea of nitrogen gas.尽管植物的叶子浸润在氮气的海洋中，但是决定植物生长上限的却是土壤中的氮元素含量。这真是自然界中的一个极大的讽刺。
