Daylight Saving Time (DST) How and When Did Daylight Saving Time Start?
A. Benjamin Franklin--of "early to bed and early 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 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 wasnt 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 artificial 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) 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 later, 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 doesnt actually save energy--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 the practice reduced lighting and electricity
consumption in the evening but increased energy use in the now dark mornings-- wiping out the evening gains. Thats 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 a wanner house, they turn on their air conditioning," the University of Washingtons 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. Department 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 those percentages seem small, they could represent significant savings because of the nations enormous total energy use.
F. Whats more, savings in some regions are apparently greater than in others. California, for instance, appears to benefit most from daylight saving time--perhaps because 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 were subject to statistical variability ( 变化) and shouldnt 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 doesnt have as much 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, 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, were clearly seeing that, at the time of daylight saving time extension in the spring, television watching is substantially reduced and outdoor behaviors like jogging, walking, or going to the park are substantially increased," Wolff said. "Thats 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 university 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 chronically (长期地) overtired, he said, is that they suffer from"social jet lag. "In other words, their optimal circadian sleep periods dont accord with their actual sleep schedules. Shifting daylight from morning to evening only increases this lag, he said. "Light doesnt do the 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 that, 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 Haters
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 extreme 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 Standardtime, on the other hand, want to abolish daylight saving time altogether, calling energy-efficiency claims "unproven. "
M. National telephone surveys by Rasmussen Reports from spring 2010 and fall 2009 deliver the same answer.Most people just "dont think the time change is worth the hassle (麻烦的事 ). " Forty-seven percent agreedwith that statement, while only 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 positive."
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 energy 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 saving time and sounded the alarm of its negative effects.
51. Social jet lag can partly account for peoples 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 considered daylight saving time does good to peoples 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 do with geographic position.【参考译文】
夏令时
夏令时是如何开始的?何时开始的?
A.享有"早睡早起"声誉的本杰明富兰克林显然是提出夏令时这一理念
的第一人。当富兰克林在巴黎担任美国驻法大使时写道，早上6点起床时他惊奇地发现，太阳升起得比平时早了很多。他由此设想，如果自己和别
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]德国是第一个采纳变化时间以减少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，有几项研究表明，夏令时并不能真正节约能源——甚至可能导致净亏损。华盛顿大学的环境经济学家亨德里克.沃尔夫与别人合著的一篇论文研究了溴大利亚的电能使用数据。当时，该国一部分地区为2000年的悉尼奥运会延长了夏令时而其他地区没有。[48]研究人员发现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，如果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。"华盛顿大学的沃尔夫如是说。
E.但是，其他研究确实发现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，把时间往前调确实能节约能源。
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。延长夏令时节约了1.3太瓦时的电量。[52]这个数字意味着。夏令时使美国年耗电量降低了0.03%，也使整体能耗减少了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庞大，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,加利福尼亚州似乎是从夏令时中获益最大的——可能是因为那里的气候相对温和，鼓励人们在户外待到更晚。能源部的报告发现，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。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，南方在能耗上却是绝对的失利方。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，夏令时的倡导者一直宣称，不管夏令时能否节约能源，它都有利于健康，因为它倡导的是积极的生活方式——目前沃尔夫及其同事正在验证这种说法。"在对全美国时间使用的研究中，我们可以很清楚地看到，在春季夏令时延长时期，看电视大幅减少，而像慢跑、散步、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响。德国慕尼黑一所大学的教授蒂尔伦内伯格说。他的研究显示，我们的生物钟是根据白天
和黑夜确定的，永远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，发达国家中的很多人长期感觉过度劳累，原因之一就是。他们遭受"社会时差"的折磨。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致。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.其他研究暗示甚至还有更严重的健康危害。[47]2008年的一项研究总结道，至少在瑞典，在春季时间变化后不久，心脏病发病率就上升了。一位专家发电子邮件告诉《国家地理新闻》说："根据我们的调查结果，最可能的解释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益处或造成的损失，大家意见不一。因此每年的时间变化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(倡导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"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"未经证实的"。
M.拉斯姆森报告所做的从2010年春季和2009年秋季开始的全国电话调查也传达了同样的信息。大多数人只是"认为时间变化不值得人们如此烦
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，他对夏令时的研究表明，多数人是喜爱夏令时制的。"我想，如果你问多数人他们是否喜欢一年八个月中每天晚上多一个小时的日照时间，他们的回答将是十分肯定的。"

Although many researchers broadly agree that public access to raw data would accelerate science, most are reluctant to post the results of their own labors online. Some communities have agreed to share online—geneticists, for example, post DNA sequence sat the GenBank repository (库) , and astronomers are accustomed to accessing images of galaxies and stars from, say, the Sloan Digital Sky Survey, a telescope that has observed some500 million objects—but these remain the excepti on, not the rule.

2018年12月英语六级阅读练习题及答案（五） Everyone has a moment in history, which belongs particularly to him. It is the moment when his emotions achieve their most powerful sway over him, and afterward when you say to this person ―the world today‖ or ―life‖ or ―reality‖ he will assume that you mean this moment, even if it is fifty years past. The world, through his unleashed(释放的)emotions, imprinted itself upon him, and he carries the stamp of that passing moment forever. For me, this momentfour years in a moment in historywas the war. The war was and is reality for me. I still instinctively live and think in its atmosphere. These are some of its characteristics: Franklin Delano Roosevelt is the president of the United States, and he always has been. The other two eternal world leaders are Winston Churchill and Joseph Stalin. America is not, never has been, and never will be what the song and poems call it, a land of plenty. Nylon, meat, gasoline, and steel are rare. There are too many jobs and not enough workers. Money is very easy to earn but rather hard to spend, because there isnt very much to buy.

Passage One Questions 52 to 56 are based on the following passage. The 35 percent of African-American youth living in poverty are the most visible victims of what is often called the achievement gap. But black children of all socioeconomic levels perform worse on national tests and graduate in fewer numbers than their white middle-class peers. A study by the U.S. Department of Education’s National Center for Education Statistics found that African-American students scored, on average, 26 points lower than white students on their reading and math tests. Some say, as Harvard psychologist Richard J. Herrnstein and American Enterprise Institute political scientist Charles Murray did in their 1994 book, The Bell Curve, that the cause is genetic. And though The Bell Curve has been discredited in scientific circles, the idea that IQ is somehow linked to race has been slow to retreat. Others, like Cornell University researchers Gary Evans and Michelle Schamberg, believe that “physiological stress is a plausible model for how poverty could get into the brain and eventually interfere with achievement,” as they wrote in Proceedings of the National Academy of Sciences. Our best efforts at narrowing the gap nationally — think No Child Left Behind —haven’t worked. But locally, there are now signs of hope. At the Harlem
2015大学英语六级阅读模拟试题及答案
大学英语六级阅读模拟试题及答案 第一篇 A scientific panel convened by the World Health Organization recommended guidelines on Friday for doctors conducting clinical studies of SARS patients. The panel urged doctors to apply the guidelines in analyzing the masses of potentially useful information about various therapies that were collected in this year’s epidemic. Much of that information has not been published or analyzed. “It is a matter of urgency to get better analysis and review,” said Dr. Simon Mardel, a WHO official who led the two-day meeting that ended on Friday. He said thousands of potential therapies and compounds had been tested so far as researchers try to determine treatments for SARS, or severe acute respiratory syndrome. “We recognize that having no treatment for SARS is hindering our ability to control an epidemic in so many ways.” He said. In the epidemic earlier this year, various treatments, like drugs to fight the virus or strengthen the immune system, as well as traditional Chinese medicine, were delivered under emergency conditions, in widely different settings and countries to patients suffering from varying stages of the illness. Those conditions—generally without standardized measurements or controlled situations—have made it hard to interpret results. Standard supportive therapy like nursing, and in severe cases the use of mechanical respirators（呼吸器）to help patients breathe, is the mainstay（主要支持）of SARS care, and helped many patients survive. But doctors still do not know how best to treat SARS patients who have breathing difficulties. Dr. Mardel said. One method is invasive ventilation. A second method involves blowing oxygen into the lungs through a mask. Both carry the risk of transmitting the virus to hospital employees. Without proper analysis, the panel was unable to say definitively which treatment worked best, or which caused the most harm. “There is a lack of shared information,” Dr. Mardel said, noting that a lot of data have not been published. The panel also agreed on guidelines that would allow doctors to conduct quick and safe clinical trials, a process that generally takes years to complete. The world Health Organization, a United Nations agency did not release the guidelines. Dr. Mardel said they were flexible because no one knew where, when and in what setting SARS would return. Experts in many countries have already listed the treatments they want to test, and the health agency is leaving these decisions to individual nations. 1. Guidelines recommended by the scientific panel can be used for _____. A. gathering potentially useful information about various therapies collected B. conducting clinical studies of SARS patients C. determining treatment for SARS D. publishing all the information about SARS
20186月大学英语六级真题、译文和详细解析汇报[仔细阅读卷二]
2018年6月大学英语六级考试仔细阅读真题解析（卷二） Section C Directions:There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A),B),C)and D).You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre. Passage One Questions 46 to 50 are based on the following passage. Economically speaking, are we better off than we were ten years ago? Twenty years ago? In their thirst for evidence on this issue, commentators seized on the recent report by the Census Bureau, which found that average household income rose by 5.2% in 2015. Unfortunately, that conclusion puts too much weight on a useful, but flawed and incomplete, statistic. Among the more significant problems with the Census’s measure are that: 1) it excludes taxes, transfers, and compensation like employer-provided health insurance; and 2) it is based on surveys rather than data. Even if precisely measured, income data exclude important determinants of economic well-being, such as the hours of work needed to earn that income. While thinking about the question, we came across a recently published article by Charles Jones and Peter Klenow, which proposes an interesting new measure of economic welfare. While by no means perfect, it is considerably more comprehensive than average income, taking into account not only growth in consumption per person but also changes in working time, life expectancy, and inequality. Moreover, it can be used to assess economic performance both across countries and over time. The Jones-Klenow method can be illustrated by a cross-country example. Suppose we want to compare the economic welfare of citizens of the U.S. and France in 2005. In 2005, as the authors observe, real consumption per person in France was only 60% as high as the U.S., making it appear that Americans were economically much better off than the French on average. However, that comparison omits other relevant factors: leisure time, life expectancy, and economic inequality. The French take longer vacations and retire earlier, so typically work fewer hours; they enjoy a higher life expectancy, presumably reflecting advantages with respect to health care, diet, lifestyle, and the like; and income and consumption are somewhat more equally distributed there than in the U.S. Because of these differences, comparing France’s consumption with the U.S.’s overstates

As soon as colonizers and explorers began taking cameras into distant lands,stories began circulating about how indigenous peoples saw them as tools for black magic.The ignorant natives may have had a point.When photography first became available,scientists welcomed it as a more objective way of recording faraway societies than early travelers' exaggerated accounts.But in some ways,anthropological photographs reveal more about the culture that holds the camera than the one that stares back.Up into the 1950s and 1960s,many ethnographers sought pure pictures of primitive cultures,routinely deleting modern accoutrements such as clocks and Western dress.They paid men and women to re-enact rituals or to pose as members of war or hunting parties,often with little regard for veracity.Edward Curtis,the legendary photographer of North American Indians,for example,got one Makah man to pose as a whaler with a spear in 1915--even though the Makah had not hunted whales in a generation. These photographs reinforced widely accepted stereotypes that indigenous cultures were isolated,primitive,and unchanging.For instance,National Geographic magazine's photographs have taught millions of Americans about other cultures.As Catherine Lutz and Jane Collins point out in their 1993 book Reading National Geographic,the magazine since its founding in 1888 has kept a tradition of presenting beautiful photos that don't challenge white,middle-class American conventions.While dark-skinned women can be shown without tops,for example,white women's breasts are taboo.Photos that could unsettle or disturb,such as areas of the world torn asunder by war or famine,are discarded in favor of those that reassure,to conform with the society's stated pledge to present only kindly visions of foreign societies.The result,Lutz and Collins say,is the depiction of an idealized and exotic world relatively free of pain or class conflict. Lutz actually likes National Geographic a lot.She read the magazine as a child,and its lush imagery influenced her eventual choice of anthropology as a career.She just thinks that as people look at the photographs of other cultures,they should be alert to the choice of composition and images. 1.The main idea of the passage is______________. [A]Photographs taken by Western explorers reflect more Westerners’ perception of the indigenous cultures and the Western values. [B]There is a complicated relationship between the Western explorers and the primitive peoples. [C]Popular magazines such as National Geographic should show pictures of the exotic and idealized worlds to maintain high sales. [D]Anthropologists ask the natives to pose for their pictures,compromising the truthfulness of their pictures. 2.We can infer from the passage that early travelers to the native lands often_________. [A]took pictures with the natives [B]gave exaggerated accounts of the native lands

We have probably all had lectures pointing out that laziness is immoral, that it is wasteful, and that lazy people will never amount to anything in life. But laziness can be more harmful than that, and it is often caused by more complex reasons rather than simple wish to avoid work. Some people who appear to be lazy are suffering from much more serious problems. They may be so distrustful of their fellow workers that they are unable to join in any group task for fear of ridicule or of having their idea stolen. These people who seem lazy may be ruined by a fear of failure that prevents fruitful work. Or other sorts of fantasies (幻想) may prevent work; some people are so busy planning, sometimes planning great deals of fantastic achievements that they are unable to deal with whatever "lesser" work is on hand. Still other people are not avoiding work; strictly speaking, they are merely procrastinating rescheduling their day.

2011年6月大学英语六级真题及答案 Part IV Reading Comprehension (Reading in Depth) (25 minutes) Section A Directions: In this section, there is a short passage with 5 questions or incomplete statements. Read the passage carefully. Then answer the questions or complete the statements in the fewest possible words. Please write your answers on Answer Sheet 2. Questions 47 to 51 are based on the following passage. How good are you at saying "no"? For many, it's surprisingly difficult. This is especially true of editors, who by nature tend to be eager and engaged participants in everything they do. Consider these scenarios: It's late in the day. That front-page package you've been working on is nearly complete; one last edit and it's finished. Enter the executive editor, who makes a suggestion requiring a more-than-modest rearrangement of the design and the addition of an information box. You want to scream: "No! It's done!" What do you do? The first rule of saying no to the boss is don't say no. She probably has something in mind when she makes suggestions, and it's up to you to find out what. The second rule is don't raise the stakes by challenging her authority. That issue is already decided. The third rule is to be ready to cite options and consequences. The boss's suggestions might be appropriate, but there are always consequences. She might not know about the pages backing up that need attention, or about the designer who had to go home sick. Tell her she can have what she wants, but explain the consequences. Understand what she's trying to accomplish and propose a Plan B that will make it happen without destroying what you've done so far. Here's another case. Your least-favorite reporter suggests a dumb story idea. This one should be easy, but it's not. If you say no, even politely, you risk inhibiting further ideas, not just from that reporter, but from others who heard that you turned down the idea. This scenario is common in newsrooms that lack a systematic way to filter story suggestions. Two steps are necessary. First, you need a system for how stories are proposed and reviewed. Reporters can tolerate rejection of their ideas if they believe they were given a fair hearing. Your gut reaction (本能反应) and dismissive rejection, even of a worthless idea, might not qualify as systematic or fair. Second, the people you work with need to negotiate a "What if ...?" agreement covering "What if my idea is turned down?" How are people expected to react? Is there an appeal process? Can they refine the idea and resubmit it? By anticipating "What if...?" situations before they happen, you can reach understanding that will help ease you out of confrontations. 47. Instead of directly saying no to your boss, you should find out __________. 48. The author's second warning is that we should avoid running a greater risk by __________. 49. One way of responding to your boss's suggestion is to explain the __________ to her and offer an alternative solution. 50. To ensure fairness to reporters, it is important to set up a system for stories to __________. 51. People who learn to anticipate "What if...?" situations will be able to reach understanding and avoid __________. Section B Directions:There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre. Passage One Questions 52 to 56 are based on the following passage. At the heart of the debate over illegal immigration lies one key question: are immigrants good or bad for the economy? The American public overwhelmingly thinks they're bad. Yet the consensus among most economists is
