51. But big dams tend not to work as intended. The Aswan Dam， for example， stopped the Nile flooding but deprived Egypt of the fertile silt that floods left- all in return for a giant reservoir of disease which is now so full of silt that it barely generates electricity.

【写作技法】段落结构写作：论点 论据。环境类话题背诵模板。

【翻译】但一些大坝不会像预期那样发挥功效。以阿斯旺大坝为例，它阻止了尼罗河洪水泛滥，但也夺走了埃及因洪水冲击而留下的肥沃土壤--随之而来的是一个疾病滋生的水库，该水库现在淤泥堆积，几乎无法发电。

52.Proper， scientific study of the impacts of dams and of the cost and benefits of controlling water can help to resolve these conflicts.

54. There is， as Robert Rubin， the treasury secretary， says， a “disjunction” between the mass of business anecdote that points to a leap in productivity and the picture reflected by the statistics.

【写作技法】1、there be句型；2、插入语；3、固定搭配：there is a disjunction between---and---. ---之间脱节。

【翻译】正如财政部长罗伯特-鲁宾所说的那样，生产力发生大幅提高的商业传奇与官方的统计数字所反映的状况之间存在着一种“脱节”。

55. Some of this can be easily explained. New ways of organizing the workplace-all that re-engineering and downsizing- are only one contribution to the overall productivity of an economy， which driven by many other factors such as joint investment in equipment and machinery， new technology， and investment in education and training. Moreover， most of the changes that companies make are intended to keep them profitable， and this need not always mean increasing productivity： switching to new markets or improving quality can matter just as much.

【写作技法】段落写作：解释原因。

【翻译】这其中的一些原因很容易解释。新的工作场所组织方式--包括所有那些重组和缩小规模的做法--只是促进某一个经济实体的综合生产力水平的一项措施，而这种生产力的提高还受到许多其他因素的驱动，如对机械设备的联合投资，采用新技术，以及在教育和培训上的投资。另外，公司的大部分改革以盈利为目的，而达到盈利的目的不一定总是要提高生产力：转入新的市场或改善产品质量也可以达到同样的效果。

56. Two other explanations are more speculative. First， some of the business restructuring of recent years may have been ineptly done. Second， even if it was well done， it may have spread much less widely than people suppose.

【写作技法】分词短语作状语

【翻译】他的同事迈克尔-比尔说，太多的公司用简单机械的方式进行重组，在没有充分考虑到长期盈利能力的情况下降低了成本。

59. Science has long had an uneasy relationship with other aspects of culture. Think of Gallileo‘s 17th-century trial for his rebelling belief before the Catholic Church or poet William Blake’s harsh remarks against the mechanistic worldview of Isaac Newton. The schism between science and the humanities has， if anything， deepened in this century.

【写作技法】1、表关系紧张；2、think of举例子；3、the n承上启下

【翻译】科学和文化的其他方面关系一直都很紧张。试想一下17世纪伽利略因为他离经叛道的理念而遭受天主教会的审判，还有诗人威廉-布莱克也尖锐批判艾萨克-牛顿的机械世界观。在本世纪，（自然）科学同人文科学之间的这种分裂更深了。

【写作技法】对比写作手法

【翻译】和世界上大多数火山不同的是，它们并不总是位于地球表面的巨大漂流板块之间的连接处；相反，许多热点区处于板块较深的内部。

64. That the plates are moving is now beyond dispute.

【写作技法】主语从句

【翻译】板块漂移这一理论现在是无可厚非。

65. The relative motion of the plates carrying these continents has been constructed in detail， but the motion of one plate with respect to another cannot readily be translated into motion with respect to the earth‘s interior.

【写作技法】分词短语作后置定语

【翻译】携带这些大陆板块漂移的相对运动已经能够被详细地阐述出来，但是一个板块相对另一板块的运动还不能轻易地解释为它们相对于地球内部的运动。

66. It is not possible to determine whether both continents are moving in opposite directions or whether one continent is stationary and the other is drifting away from it.

About 50 percent of the companies lose when injured customers take them to court.

【写作技法】for example举例充当插入语

【翻译】虽然警示语常常是合理而且是必要的，例如关于药物相互作用会产生危险的警示语，并且许多警示语是州或联邦法律所规定的，但是如果消费者受伤，这些警示语能否真正使制造商和销售商免于职责，这还很难说。当受伤的消费者把公司告上法庭后，大约一半的结果是公司败诉。

69. With regard to Futurist poetry， however， the case is rather difficult， for whatever Futurist poetry may be-even admitting that the theory on which it is based may be right-it can hardly be classed as Literature.

【写作技法】介词短语开头 插入语 it句型

【翻译】然而，就未来派诗歌而言，情况却大不相同，因为无论未来派诗歌是什么--即使承认其理论根据可能正确--也很难称之为文学。

70. In the first year or so of Web business， most of the action has revolved around efforts to tap the consumer market.

【写作技法】状语开头

【翻译】在互联网刚开始的一两年中，大部分业务活动都是围绕着努力开发消费者市场来进行的。
