In a society that literally runs on electric power, the very idea seems preposterous. But for more than a decade, a growing band of scientists and journalists has pointed to studies that seem to link exposure to electromagnetic fields with increased risk of leukemia and other maligna高考资源网ncies. The implications are unsettling, to say the least, since everyone comes into contact with such fields, which are generated by everything electrical, from power lines and antennas to personal computers and micro-wave ovens. Because evidence on the subject is inconclusive and often contradictory, it has been hard to decide whether concern about the health effects of electricity is legitimateor the worst kind of paranoia. w*w*w*k*s*5*u*c*o*m Now the alarmists have gained some qualified support from the U. S. Environmental Protection Agency. In the executive summary of a new scientific review, released in draft form late last week, the EPA has put forward what amounts to the most serious government warning to date. The agency tentatively concludes that scientific evidence “suggests a casual link” between extremely low-frequency electromagnetic fieldsthose having very longwave-lengthsand leukemia, lymphoma and brain cancer, While the report falls short of classifying ELF fields as probable carcinogens, it does identify the common 60-hertz magnetic field as “a possible, but not proven, cause of cancer in humans. ”The report is no reason to panicor even to lost sleep. If there is a cancer risk, it is a small one. The evidence is still so controversial that the draft stirred a great deal of debate within the Bush Administration, and the EPA released it over strong objections from the Pentagon and the Whit House. But now no one can deny that the issue must be taken seriously and that much more research is needed. At the heart of the debate is a simple and well-understood physical phenomenon: When an electric current passes through a wire, tit generates an electromagnetic field that exerts forces on surrounding objects, For many years, scientists dismissed any suggestion that such forces might be harmful, primarily because they are so extraordinarily weak. The ELF magnetic field generated by a video terminal measures only a few milligauss, or about one-hundredth the strength of the earths own magnetic field, The electric fields surrounding a power line can be as high as 10 kilovolts per meter, but the corresponding field induced in human cells will be only about 1 millivolt per meter. This is far less than the electric fields that the cells themselves generate. How could such minuscule forces pose a health danger? The consensus used to be that they could not, and for decades scientists concentrated on more powerful kinds of radiation, like X-rays, that pack sufficient wallop to knock electrons out of the molecules that make up the human body. Such “ionizing” radiations have been clearly linked to increased cancer risks and there are regulations to control emissions. But epidemiological studies, which find statistical associations between sets of data, do not prove cause and effect. Though there is a body of laboratory work showing that exposure to ELF fields can have biological effects on animal tissues, a mechanism by which those effects could lead to cancerous growths has never been found. The Pentagon is for from persuaded. In a blistering 33-page critique of the EPA report, Air Force scientists charge its authors with having “biased the entire document” toward proving a link. “Our reviewers are convinced that there is no suggestion that (electromagnetic fields) present in the environment induce or promote cancer,” the Air Force concludes. “It is astonishing that the EPA would lend its imprimatur on this report. ” Then Pentagons concern is understandable. There is hardly a unit of the modern military that does not depend on the heavy use of some kind of electronic equipment, from huge ground-based radar towers to the defense systems built into every warship and plane. 1. The main idea of this passage is A. studies on the cause of cancerB. controversial view-points in the cause of cancerC. the relationship between electricity and cancer. D. different ideas about the effect of electricity on caner. 2. The view-point of the EPA is A. there is casual link between electricity and cancer. B. electricity really affects cancer. C. controversial. D. low frequency electromagnetic field is a possible cause of cancer3. Why did the Pentagon and Whit House object to the release of the report? BecauseA. it may stir a great deal of debate among the Bush Administration. B. every unit of the modern military has depended on the heavy use of some kind of electronic equipment. C. the Pentagons concern was understandable. D. they had different arguments. 4. It can be inferred from physical phenomenonA. the force of the electromagnetic field is too weak to be harmful. B. the force of the electromagnetic field is weaker than the electric field that the cells generate. C. electromagnetic field may affect health. D. only more powerful radiation can knock electron out of human body. 5. What do you think ordinary citizens may do after reading the different arguments?A. They are indifferent. B. They are worried very much. C. The may exercise prudent avoidance. C. They are shocked.

This is far less than the electric fields that the cells themselves generate. 【参考译文】这远比细胞所产生的电磁场低的多。6. and for decades scientists concentrated on more powerful kinds of radiation, like X-rays, that pack sufficient wallop to knock electrons out of the molecules that make up the human body. 【参考译文】而且几十年来，科学家专注于更为强大的辐射类别，如光射线，其聚合的冲击力足以把电子从组成人体的分子中撞出来。7. But epidemiological studies, which find statistical associations between sets of data, do not prove cause and effect. 【参考译文】可是流行病学的研究发现，几组资料在数据方面有所关联，却没有证实其因果关系。8. a body of laboratory work 一批研究成果。9. In a blistering 33-page critique of the EPA report, Air Force scientists charge its authors with having “biased the entire document” toward proving a link. 【参考译文】在长达33页的对环保署文件的十分尖锐的批评中，空军方面的科学家指责，作者歪曲整个文件以证明癌症和电磁场之间的关联。10. It is astonishing that the EPA would lend its imprimatur on this report. 【参考译文】令人惊讶的是环保署竟然批准许可这份报告的出笼。写作方法与文章大意文章以问答的方式，对比的写作方法，写出了围绕电力是否影响健康是否致癌因素的两种观点，及其观点的依据。一种是美国环境保护署为代表的：极低频磁场是一种可能但还未被证实的致癌因素，而且无视白宫和五角大楼反对，公布了这份报告。理由是科学证据提出了两者之间的关联偶然性。另一种以空军中科学家为主的观点：电磁场不会诱发或触发癌症，而且以歪曲整个文件来证明两者之关系，批评了环保署。其理由人人皆知。因军队中任一单位都有点从地面雷达到舰艇飞机防卫系统。答案详解1. D 电力对癌症影响的不同观点。文章一开始就提出了“电会致癌吗？”这个问题。十多年来，一大批科学家和新闻界人士都指出：研究结果似乎表示：接触电磁场可能会增加患白血病和其他恶性肿瘤的危险性。所以说到目前为止还难以确定电力对健康的影响究竟是理性的，还是杞人忧天。见难句注释1。第二段公布了环保署的报告，见难句注释3。第三段说明：即使有致癌危险也是极微的。但应予以认真对待，进行更多的研究。而第七段中空军方面的科学家还没有被说服（见难句注释9），明确提出，我们的评论员认为没有迹象说明环境中存在的电力会诱发或促发癌症。A. 对致癌因素的研究。B. 致癌原因方面有争议的观点，这两项根本部队，和文内电力毫无关系。C. 电力和癌症的关系，文中涉及的是电力究竟会不会致癌的两种观点，而不是两者之关系。2. A. 电和致癌有一定难以确定的关系。答案在第二段第三句，环保署目前的结论是据科学证据指出极低频电磁场具有长波的电磁场和白血病，淋巴瘤及脑癌之间有着难以确定的联系，见难句注释3。A. 电确实致癌，不对。C. 有争议的。说的不够清楚，争议什么。D. 低频磁场是一个可能致癌因素。这只是论点的一面。3. B. 现代军事的任何部门都一直依赖于应用大量应用电子设备。五角大楼和白宫所以反对环保署公布报告之理由就在此。空军方面的专家所以说环保署方面的报告“歪曲了整个文件以证明两者之间的关系”也在此。见难句注释4。所以文内说“角大楼的关注是可以理解的。”A. 报告会在布什政府内引起大规模的辩论，这是结果。C. 五角大楼的关注是可以理解的，这不是原因。D. 他们有不同的观点。4. 磁场力太弱不会产生有害作用。答案在第四段第二，三句，当电流通过电缆，产生磁场，对周围物体产生（影响）力。许多年来，科学家把任何有关“这些力可能有害的想法”置于一边（不予考虑），主要是因为它们（所产生的力）非常弱。B. 磁场力比细胞产生的电磁场弱。只是明确指出的事实。C. 磁场力对人的健康有害。不对。D. 只有更强的辐射才能把人体中的电子击出来。不对。5. C. 他们会采取谨慎小心避开电器的途径。因为他们不可能象A项那样漠不关心。这种问题直接影响人的生命。B. 他们非常担忧。D. 他们感到震惊，这两项都不可能，因为还在争议中，唯一的途径是尽量避开和电器接触。 Passage Two Religion and RationalityYet the difference in tome and language must strike us, so soon as it is philosophy that speaks: that change should remind us that even if the function of religion and that of reason coincide, this function is performed in the two cases by very different organs. Religions are many, reason one. Religion consists of conscious ideas, hopes, enthusiasms, and objects of worship; it operates by grace and flourishes by prayer. Reason, on the other hand, is a mere principle or potential order, on which indeed we may come to reflect but which exists in us ideally only, without variation or stress of any kind. We conform or do not conform to it; it does not urge or chide us, not call for any emotions on our part other than those naturally aroused by the various objects which it unfolds in their true nature and proportion. Religion brings some order into life by weighting it with new materials. Reason adds to the natural materials only the perfect order which it introduces into them. Rationality is nothing but a form, an ideal constitution which experience may more or less embody. Religion is a part of experience itself, a mass of sentiments and ideas. The one is an inviolate principle, the other a changing and struggling force. And yet this struggling and changing force of religion seems to direct man toward something eternal. It seems to make for an ultimate harmony within the soul and for an ultimate harmony between the soul and all that the soul depends upon. Religion, in its intent, is a more conscious and direct pursuit of the Life of Reason than is society, science, or art, for these approach and fill out the ideal life tentatively and piecemeal, hardly regarding the foal or caring for the ultimate justification of the instinctive aims. Religion also has an instinctive and blind side and bubbles up in all manner of chance practices and intuitions; soon, however, it feels its way toward the heart of things, and from whatever quarter it may come, veers in the direction of the ultimate. w*w*w*k*s*5*u*c*o*m Nevertheless, we must confess that this religious pursuit of the Life of Reason has been singularly abortive. Those within the pale of each religion may prevail upon themselves, to express satisfaction with its results, thanks to a fond partiality in reading the past and generous draughts of hope for the future; but any one regarding the various religions at once and comparing their achievements with what reason requires, must feel how terrible is the disappointment which they have one and all prepared for mankind. Their chief anxiety has been to offer imaginary remedies for mortal ills, some of which are incurable essentially, while others might have been really cured by well-directed effort. The Greed oracles, for instance, pretended to heal out natural ignorance, which has its appropriate though difficult cure, while the Christian vision of heaven pretended to be an antidote to our natural deaththe inevitable correlate of birth and of a changing and conditioned existence. By methods of this sort little can be done for the real betterment of life. To confuse intelligence and dislocate sentiment by gratuitous fictions is a short-sighted way of pursuing happiness. Nature is soon avenged. An unhealthy exaltation and a one-sided morality have to be followed by regrettable reactions. When these come. The real rewards of life may seem vain to a relaxed vitality, and the very name of virtue may irritate young spirits untrained in and natural excellence. Thus religion too often debauches the morality it comes to sanction and impedes the science it ought to fulfill. What is the secret of this ineptitude? Why does religion, so near to rationality in its purpose, fall so short of it in its results? The answer is easy; religion pursues rationality through the imagination. When it explains events or assigns causes, it is an imaginative substitute for science. When it gives precepts, insinuates ideals, or remoulds aspiration, it is an imaginative substitute for wisdomI mean for the deliberate and impartial pursuit of all food. The condition and the aims of life are both represented in religion poetically, but this poetry tends to arrogate to itself literal truth and moral authority, neither of which it possesses. Hence the depth and importance of religion becomes intelligible no less than its contradictions and practical disasters. Its object is the same as that of reason, but its method is to proceed by intuition and by unchecked poetical conceits. 1.
