6、s.”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

7、.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

8、 objects,For many years,scientists dismissed any -1-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

9、,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 healt

10、h 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

11、 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,

12、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 convin

16、3.Why did the Pentagon and Whit House object to the release of the report?Because A.it may stir a great deal of debate among the Bush Administration.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

17、had different arguments.4.It can be inferred from physical phenomenon A.the force of the electromagnetic field is too weak to be harmful.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 rad

19、 恶性肿瘤 4.legitimate 合法的，合理的 5.paranoia 偏执狂，妄想狂。这里指：无根据的担心。6.lymphoma 淋巴瘤 7.carcinogen 致癌物 -1-8.minuscule 很小的，很不重要 9.consensus 舆论 10.wallop 乱窜，猛冲，冲击力 11.epidemiological 流行病学的 12.blistering 罗嗦的，胡扯的 13.critique 评论，批评 14.imprimatur 出版许可（官方审查后的），批准 难句译注 1.Because evidence on the subject is inconclusive an

20、d often contradictory,it has been hard to decide whether concern about the health effects of electricity is legitimateor the worst kind of paranoia.参考译文 由于这问题的证据还不是结论性的，而且常常是矛盾的，所以就难以断定有关电力对身体的影响的顾虑是合乎情理，还是毫无根据的怀疑。2.EPAU.S.Environmental Protection Agency 美国环境保护署 3 While the report falls short(缺乏，不够)

21、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.”参考译文 虽然报告没有把极低频磁场归类为可能致癌物，但它确实指出通常 60 赫兹的磁场是“一种虽尚未证实，但可能导致人患癌症的因素。”4 The evidence is still so controversial that the draft stirred a great dea

22、l of debate within the Bush Administration,and the EPA released it over strong objections from the Pentagon and the Whit House 参考译文 证据争议性仍然很大，所以报告草案在布什政府内引起巨大的争辩，而环保署无视无角大楼和白宫的强烈反对，公布了这份报告。5.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。-1-6.and fo

23、r 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 association

24、s 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

25、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

26、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。答案祥解 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 -1-三段说明：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

27、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

28、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.A.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

29、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。【2014 高考英语陕西省一模联考试题】D Everyone has done experiments in high school laboratories,but have you ever thought about designing a satellite to explore space?-1-On Nov

40、，选出最佳选项。The Board Meeting had come to an end.Bob started to stand up and knocked into the table,spilling his coffee over his notes.“How embarrassing!I am getting so clumsy in my old age.”Everyone had a good laugh,and soon we were all telling stories of our most embarrassing moments.It came around to

41、 Frank who sat quietly listening to the others.Someone said,“Come on,Frank.Tell us your most embarrassing moment.”Frank laughed and began to tell us of his childhood.“I grew up in San Pedro.My Dad was a fisherman,and he loved the sea.He had his own boat,but it was hard making -1-a living on the sea.

42、He worked hard and would stay out until he caught enough to feed the family.Not just enough for our family,but also for his Mom and Dad and the other kids that were still at home.”He looked at us and said,“I wish you could have met my Dad.He was a big man,and he was strong from pulling the nets and

43、fighting the seas for his catch.When you got close to him,he smelled like the ocean.He would wear his old canvas,foul-weather coat and his bibbed overalls.His rain hat would be pulled down over his brow.No matter how much my mother washed them,they would still smell of the sea and of fish.”Franks vo

44、ice dropped a bit.“When the weather was bad he would drive me to school.He had this old truck that he used in his fishing business.That truck was older than he was.It would wheeze and rattle down the road.You could hear it coming for blocks.As he would drive toward the school,I would shrink(畏缩)down

45、into the seat hoping to disappear.Half the time,he would slam to a stop and the old truck would belch(喷出)a cloud of smoke.He would pull right up in front,and it seemed like everybody would be standing around and watching.Then he would lean over and give me a big kiss on the cheek and tell me to be a
