2、to rise" fame-was apparently the first person to suggest the concept of daylight savings. While serving as U.S. ambassador to France in Pads, Franklin wrote of being awakened at 6 a.m. and realizing, to his surprise, that the sun would rise far earlier than he usually did. Imagine the resources
3、 that might be saved if he and others rose before noon and burned less midnight oil, Franklin, tongue half in cheek, wrote to a newspaper. B. It wasn't until World War I that daylight savings were realized on a grand scale. Germany was the first state to adopt the time changes, to reduce artific
4、ial lighting and thereby save coal for the war effort. Friends and foes soon followed suit. In the U.S. a federal law standardized the yearly start and end of daylight saving time in 1918-for the states that chose to observe it. C. During World War II the U.S. made daylight saving time mandatory(强制的
5、) for the whole country, as a way to save wartime resources. Between February 9, 1942, and September 30, 1945, the government took it a step further. During this period daylight saving time was observed year-round, essentially making it the new standard time, if only for a few years. Many years late
6、r, the Energy Policy Act of 2005 was enacted, mandating a controversial month-long extension of daylight saving time, starting in 2007.Daylight Saving Time: Energy Saver or Just Time Sucker? D. In recent years several studies have suggested that daylight saving time doesn't actually save energy-
7、and might even result in a net loss. Environmental economist Hendrik Wolff, of the University of Washington, co- authored a paper that studied Australian power-use data when parts of the country extended daylight saving time for the 2000 Sydney Olympics and others did not. The researchers found that
8、 the practice reduced lighting and electricity consumption in the evening but increased energy use in the now dark mornings- wiping out the evening gains. That's because the extra hour that daylight saving time adds in the evening is a hotter hour. "So if people get home an hour earlier in
9、a wanner house, they turn on their air conditioning," the University of Washington's Wolff said. E. But other studies do show energy gains. In an October 2008 daylight saving time report to Congress, mandated by the same 2005 energy act that extended daylight saving time, the U.S. Departmen
10、t of Energy asserted that springing forward does save energy. Extended daylight saving time saved 1.3 terawatt ( 太瓦 ) hours of electricity. That figure suggests that daylight saving time reduces annual U.S. electricity consumption by 0.03 percent and overall energy consumption by 0.02 percent. While
11、 those percentages seem small, they could represent significant savings because of the nation's enormous total energy use. F. What's more, savings in some regions are apparently greater than in others. California, for instance, appears to benefit most from daylight saving time-perhaps becaus
12、e its relatively mild weather encourages people to stay outdoors later. The Energy Department report found that daylight saving time resulted in an energy savings of one percent daily in the state. G. But Wolff, one of many scholars who contributed to the federal report, suggested that the numbers w
13、ere subject to statistical variability ( 改变) and shouldn't be taken as hard facts. And daylight savings' energy gains in the U.S. largely depend on your location in relation to the Mason-Dixon Line, Wolff said."The North might be a slight winner, because the North doesn't have as mu
14、ch air conditioning," he said. "But the South is a definite loser in terms of energy consumption. The South has more energy consumption under daylight saving." Daylight Saving Time: Healthy or Harmful? H. For decades advocates of daylight savings have argued that, energy savings or no
15、, daylight saving time boosts health by encouraging active lifestyles-a claim Wolff and colleagues are currently putting to the test. "In a nationwide American time-use study, we're clearly seeing that, at the time of daylight saving time extension in the spring, television watching is subs
16、tantially reduced and outdoor behaviors like jogging, walking, or going to the park are substantially increased," Wolff said. "That's remarkable, because of course the total amount of daylight in a given day is the same. " I. But others warn of ill effects. Till Roenneberg, a univ
17、ersity professor in Munich (慕尼黑), Germany, said his studies show that our circadian (生理节奏的 ) body clocks-set by light and darkness-never adjust to gaining an "extra" hour of sunlight to the end of the day during daylight saving time. J. One reason so many people in the developed world are
18、chronically (长期地) overtired, he said, is that they suffer from"social jet lag. "In other words, their optimal circadian sleep periods don't accord with their actual sleep schedules. Shifting daylight from morning to evening only increases this lag, he said. "Light doesn't do t
19、he same things to the body in the morning and the evening. More light in the morning would advance the body clock, and that would be good. But more light in the evening would even further delay the body clock. " K. Other research hints at even more serious health risks. A 2008 study concluded t
20、hat, at least in Sweden, heart attack risks go up in the days just after the spring time change. "The most likely explanation to our findings is disturbed sleep and disruption of biological rhythms," One expert told National Geographic News via email. Daylight Savings' Lovers and Hater
21、s L. With verdicts (定论) on the benefits, or costs, of daylight savings so split, it may be no surprise that the yearly time changes inspire polarized reactions. In the U.K., for instance, the Lighter Later movement-part of 10:10,a group advocating cutting carbon emissions-argues for a sort of extrem
22、e daylight savings. First, they say,move standard time forward an hour, then keep observing daylight saving time as usual-adding two hours ofevening daylight to what we currently consider standard time. The folks behind S, on the other hand, want to abolish daylight saving time altogether, calling e
23、nergy-efficiency claims "unproven. " M. National telephone surveys by Rasmussen Reports from spring 2022 and fall 2009 deliver the same answer.Most people just "don't think the time change is worth the hassle (麻烦的事 ). " Forty-seven percent agreedwith that statement, while onl
24、y 40 percent disagreed. But Seize the Daylight author David Prerau said his research on daylight saving time suggests most people are fond of it."I think if you ask most people if they enjoy having an extra hour of daylight in the evening eight months a year, the response would be pretty positi
25、ve." 46. Daylight savings' energy gains might be various due to different climates. 47. Disturbed sleep and disruption of biological rhythms may be the best explanation to higher heart attack risks in the days after the spring time change. 48. A research indicated that DST might not save en
26、ergy by increasing energy use in the dark mornings, though it reduced lighting and electricity consumption in the evening. 49. Germany took the lead in saving wardme resources by adopting the time changes and reducing artificiallighting. 50. A university professor studied the effect of daylight savi
27、ng time and sounded the alarm of its negative effects. 51. Social jet lag can partly account for people's chronic fatigue syndrome in developed countries. 52. The figure of a study in the U.S. suggested that DST could save a lot of energy nationally. 53. Supporters of daylight savings have long
28、considered daylight saving time does good to people's health. 54. A group advocating cutting carbon emissions launches the Lighter Later movement to back a kind of extreme daylight savings. 55. A scholar contributing to a federal report suggested that the amount of saved energy had something to
29、do with geographic position. 【参考译文】 夏令时 夏令时是如何起先的?何时起先的? A.享有;早睡早起;声誉的本杰明·富兰克林明显是提出夏令时这一理念的第一人。当富兰克林在巴黎担当美国驻法大使时写道，早上6点起床时他惊异地发觉，太阳升起得比平常早了许多。他由此设想，假如自己和别人都少挑灯熬夜并在中午之前起床，那么就有可能节约资源。于是，他就以半开玩笑的口吻给一家报社写了信。 B.直到第一次世界大战夏令时才获得广泛认可。49德国是第一个接受改变时间以削减人工照明从而为战事节约煤炭资源这一做法的国家。很快，不论敌国还是友邦都纷纷效仿。1918年，美国的一
30、部联邦法律为那些选择遵守夏令时的州制定标准，规定了每年夏令时的起止日期。 C.二战期间，美国在全国强制执行夏令时，以此来节约战时的资源。在1942年2月9日至l945年9月30日期间，政府进一步推行夏令时。在这期间，全年都要遵守夏令时，这几年基本上都把它作为新的标准时间。多年以后，能源政策法案于2005年颁布，强制规定从2007年起将夏令时延长一个月。这个规定曾颇有争议。 夏令时：节能还是耗时? D.近年来，有几项探讨表明，夏令时并不能真正节约能源——甚至可能导致净亏损。华盛顿高校的环境经济学家亨德里克.沃尔夫与别人合著的一篇论文探讨了溴大利亚的电能运用数据。当时，该国
31、一部分地区为2000年的悉尼奥运会延长了夏令时而其他地区没有。48探讨人员发觉这种做法降低了杰盟的照明及电量消耗。但是却增加了晨间的用电量。因为现在早晨很昏暗——这就抵消了夜间节约的能源。这是因为夏令时在夜间所增加的一个小时正是很热的时候。;所以，假如人们提前一小时回家，回到比以往更热的房子里，他们就会打开空调。;华盛顿高校的沃尔夫如是说。 E.但是，其他探讨的确发觉夏令时可以带来节能收益。美国能源部在2008年10月份给国会的夏令时报告中称，把时间往前调的确能节约能源。这份报告同样是由2005年延长夏令时的能源法案所授权发布的。延长夏令季节约了1.3太瓦时的电量。52
32、这个数字意味着。夏令时使美国年耗电量降低了0.03%，也使整体能耗削减了0.02%。尽管这些百分比看起来很小，但是，由于国家总能耗量很浩大，它们所代表的节能量还是很大的。 F.46此外，一些地区的节能量明显比其他地区要大。例如,加利福尼亚州好像是从夏令时中获益最大的——可能是因为那里的气候相对温柔，激励人们在户外待到更晚。能源部的报告发觉，夏令时使这个州每日能耗量节约了1%。 G.但是作为为联邦报告撰稿的诸多学者之一，沃尔夫却表示，这些数字可能会受统计变动的影响，不应将其视为铁的事实。55沃尔夫表示，夏令时给美国带来的能源收益主要取决于某个地区与梅森一狄克森线的相对位置
33、。他说：;北方在节能上可能略有优势，因为北方没有那么多空调。但是，南方在能耗上却是肯定的失利方。实行夏令时，南方会消耗更多能源。;夏令时：健康的还是有害的? H.53几十年来，夏令时的提倡者始终宣称，不管夏令时能否节约能源，它都有利于健康，因为它提倡的是主动的生活方式——目前沃尔夫及其同事正在验证这种说法。;在对全美国时间运用的探讨中，我们可以很清晰地看到，在春季夏令时延长时期，看电视大幅削减，而像慢跑、漫步、逛公园这类的户外活动却大幅增多了。;沃尔夫说道，;这是很好的现象，当然这是因为某一特定日期的白昼长度是一样的。; I.50但是其他人却警告人们夏令时所带来的负面影
34、响。德国慕尼黑一所高校的教授蒂尔伦内伯格说。他的探讨显示，我们的生物钟是依据白天和黑夜确定的，恒久都适应不了夏令时期间白天快结束时所多出的那;额外;一小时的日光。 J.51他说，发达国家中的许多人长期感觉过度劳累，缘由之一就是。他们遭遇;社会时差;的熬煎。换句话说，他们的最佳生理节奏睡眠期与他们实际的睡眠时间不一样。他还说，把日光从早晨转移到晚上只会加重这种时差。;光线对人体的作用在早上和晚上是不一样的。早上的光线更多会促进生物钟，这是有益的。但是，晚上的光线更多则会进一步推迟生物钟。; K.其他探讨示意甚至还有更严峻的健康危害。472008年的一项探讨总结道，至少在瑞典，在春季时间改变后不久
35、，心脏病发病率就上升了。一位专家发电子邮件告知国家地理新闻说：;依据我们的调查结果，最可能的说明是睡眠障碍及生物节奏紊乱。; 对夏令时是爱还是恨? L.对夏令时所能带来的好处或造成的损失，大家看法不一。因此每年的时间改变都会引起两极分化的回应也就不足为奇了。例如，54在英国，;晚亮灯运动;——作为10：10(提倡降低碳排放量的一个组织)开展的运动的一部分——提倡一种极端的日光节约时制。他们说，首先要把标准时间提前一个小时，然后同以往一样遵守夏令时——这会给我们目前所认为的标准时间增加两个小时的夜间时间。另一方面，;标准时间
36、;网的支持者则想完全废除夏令时。他们称那些节能的说法都是;未经证明的;。 M.拉斯姆森报告所做的从2022年春季和2009年秋季起先的全国电话调查也传达了同样的信息。大多数人只是;认为时间改变不值得人们如此苦恼;。47%的人赞同这一说法，而只有40%的人不赞同。然而，一寸光阴一寸金的作者戴维·普雷劳说，他对夏令时的探讨表明，多数人是宠爱夏令时制的。;我想，假如你问多数人他们是否喜爱一年八个月中每天晚上多一个小时的日照时间，他们的回答将是非常确定的。; 【答案解析】 46.F 解析：题干意为，夏令时带来的能源收益可能会因为不同的气候而有差异。留意抓住题干中的关键词daylight
