阅读理解Have you winterized your horse yet? Even though global warming may have made our climatemilder, many animals are still hibernating. Its too bad that humans cant hibernate. In fact, as aspecies, we almost did.Apparently, at times in the past, peasants in France liked a semi-state of human hibernation. Sowrites Graham Robb, a British scholar who has studied the sleeping habits of the French peasants. Assoon as the weather turned cold people all over France shut themselves away and practiced theforgotten art of doing nothing at all for months on end.In line with this, Jeff Warren, a producer at CBC Radios The Current, tells us that the way we sleephas changed fundamentally since the invention of artificial lighting and the electric bulb.When historians began studying texts of the Middle Ages, they noticed something referred to as“first sleep”, which was not clarified, though. Now scientists are telling us our ancestors most likelyslept in separate periods. The business of eight hours uninterrupted sleep is a modern invention.In the past, without the artificial light of the city to bathe in, humans went to sleep when it becamedark and then woke themselves around midnight. The late night period was known as “The Watch”.It was when people actually kept watch against wild animals, although many of them simply movedaround or visited family and neighbors.According to some sleep researchers, a short period of insomnia at midnight is not a disorder. It isnormal. Humans can experience another state of consciousness around their sleeping, which occursin the brief period before we fall asleep or wake ourselves in the morning. This period can be anextraordinarily creative time for some people. The impressive inventor, Thomas Edison, used thisstate to hit upon many of his new ideas.Playing with your sleep rhythms can be adventurous, as anxiety may set in. Medical science doesnthelp much in this case. It offers us medicines for a full nights continuous sleep, which sounds natural;however, according to Warrens theory, it is really the opposite of what we need.

阅读理解 America doesn't have a worker shortage; it has a work shortage. The unemployment rate is at a 15-year low, but only 55% of American adults 18 to 64 have fulltime jobs. Nearly 95 million people have removed themselves entirely from the job market. According to demographer Nicholas Eberstadt, the labor-force participation rate for men ages 25 to 54 is lower now than it was at the end of the Great Depression. The welfare state is largely to blame. More than 20% of American men of prime working age are on Medicaid. According to the Census Bureau, nearly 60% of nonworking men receive federal disability benefits. The good news is that the 1996 welfare reform taught us how to reduce government dependency and get idle Americans back to work. Attaching work requirements to social benefits like Medicaid, food stamps, Social Security Disability Insurance and Supplemental Security Income would make what these pages have called 'America's growing labor shortage' a nonissue. According to the Kaiser Family Foundation, 41% of nondisabled adults on Medicaid don't have jobs. Thirteen million Americans ages 18 to 54 currently receive SSDI or SSI benefits. Conservatively, work requirements could add 25% of that population (3.3 million workers) back to the labor force. Work requirements for people on food stamps would increase the worker rolls by 1.9 million if only 10% who aren't engaged in work rejoined. There's no question that insisting on work in exchange for social benefits would succeed in reducing dependency. We have the data: Within 10 years of the 1996 reform, the number of Americans in the Temporary Assistance for Needy Families program fell 60%. But no reform is permanent. Under President Obama, federal poverty programs ballooned. A better long-term solution to the work shortage would be to eliminate all forms of public support except for those who are unable to work, and eliminate all poverty programs, since they haven't reduced poverty since they were established in 1965. The money being spent on these programs should be redirected to job creation—preferably for private-sector jobs, but public-sector jobs will do in a pinch. A trillion-dollar federal infrastructure program, such as the one President Trump has said he will propose, could absorb a large number of the unemployed and underemployed. There are other avenues to pursue. For young men who aren't working, a mandatory two-year public-service requirement with an off-ramp for those who snag a job could motivate them to get off—and stay off—the couch. Too many Americans who could be available to help fuel robust economic growth are instead sitting on the sidelines. It's time to get them in the game. It's time to solve the work shortage.

阅读理解 In his book The Tipping Point, Malcolm Gladwell argues that 'social epidemics' are driven in large part by the actions of a tiny minority of special individuals, often called influentials, who are unusually informed, persuasive, or well connected. The idea is intuitively compelling--we think we see it happening all the time--but it doesn't explain how ideas actually spread. The supposed importance of influentials derives from a plausible-sounding but largely untested theory called the 'two-step flow of communication': Information flows from the media to the influentials and from them to everyone else. Marketers have embraced the two-step flow because it suggests that if they can just find and influence the influentials, those select people will do most of the work for them. The theory also seems to explain the sudden and unexpected popularity of certain looks, brands, or neighborhoods. In many such cases, a cursory search for causes finds that some small group of people was wearing, promoting or developing whatever it is before anyone else paid attention. Anecdotal evidence of this kind fits nicely with the idea that only certain special people can drive trends. In their recent work, however, some researchers have come up with the finding that influentials have far less impact on social epidemics than is generally supposed. In fact, they don't seem to be required at all. The researchers' argument stems from a simple observation about social influence, with the exception of a few celebrities like Oprah Winfrey--whose outside presence is primarily a function of media, not interpersonal influence--even the most influential members of a population simply don't interact with that many others. Yet it is precisely these non-celebrity influentials who, according to the two-step-flow theory, are supposed to drive social epidemics, by influencing their friends and colleagues directly. For a social epidemic to occur, however, each person so affected must then influence his or her own acquaintances, who must in turn influence theirs, and so on; and just how many others pay attention to each of these people has little to do with the initial influential. If people in the network just two degrees removed from the initial influential prove resistant, for example, the cascade of change won't propagate very far or affect many people. Building on the basic truth about interpersonal influence, the researchers studied the dynamics of populations, manipulating a number of variables relating to people's ability to influence others and their tendency to be influenced.

阅读理解The first ancient Olympics were held in 776 B.C.. The games got their name from Olympia, the Greek city where they took place. Like the Summer Olympics of today, the ancient Olympics were held every four years. Thousands of people from all over the Greek world came to watch. The main stadium held about 45,000 people. "We have accounts of visitors and pilgrims setting up tents all around the site," Lisa Cerrato of Tufts University said. During the first Olympics, there was only one competition — a 200-meter race. But over time the games grew to include wrestling, chariot racing boxing, and other sports. Women were not allowed to compete, but they had their own separate games. "The ancient athletes became celebrities (名人) , just like today. They often lived the rest of their lives being treated to free dinners." Cerrato said. "City-states even tried to steal away each other''s athletes by offering them various awards." The ancient Olympics existed until 393 AD. But the modern Olympics are still going strong.

阅读理解 Add CO2 to the atmosphere and the climate will get warmer—that much is well established. But climate change and carbon aren't in a one-to-one relationship. If they were, climate modeling would be a cinch. How much the globe will warm if we put a certain amount of CO2 into the air depends on the sensitivity of the climate. How vulnerable is the polar sea ice; how rapidly might the Amazon dry up; how fast could the Greenland ice cap disintegrate? That's why models like those from the Intergovernmental Panel on Climate Change spit out a range of predictions for future warming, rather than a single neat number. One of the biggest questions in climate sensitivity has been the role of low-level cloud cover. Low-altitude clouds reflect some of the sun's radiation back into the atmosphere, cooling the earth. It's not yet known whether global warming will dissipate clouds, which would effectively speed up the process of climate change, or increase cloud cover, which would slow it down. But a new study published in the July 24 issue of Science is clearing the haze. A group of researchers from the University of Miami studied cloud data of the northeast Pacific Ocean over the past 50 years and combined that with climate models. They found that low-level clouds tend to dissipate as the ocean warms—which means a warmer world could well have less cloud cover. 'That would create positive feedback, a reinforcing cycle that continues to warm the climate,' says Amy Clement, the leading author of the Science study. The data showed that as the Pacific Ocean has warmed over the past several decades—part of the gradual process of global warming—low-level cloud cover has lessened. That might be due to the fact that as the earth's surface warms, the atmosphere becomes more unstable and draws up water vapor from low altitudes to form deep clouds high in the sky. (Those types of high-altitude clouds don't have the same cooling effect.) The Science study also found that as the oceans warmed, the trade winds—the easterly surface winds that blow near the equator—weakened, which further dissipated the low clouds. The question now is whether this process will continue in the future, as the world keeps warming.

阅读理解It is hardly necessary for me to cite all the evidence of the depressing state of literacy. These figuresfrom the Department of Education are sufficient: 27 million Americans cannot read at all, and afurther 35 million read at a level that is less than sufficient to survive in our society.But my own worry today is less that of the overwhelming problem of elemental literacy than it is ofthe slightly more luxurious problem of the decline in the skill even of the middle-class reader, of hisunwillingness to afford those spaces of silence, those luxuries of domesticity and time andconcentration, that surround the image of the classic act of reading. It has been suggested that almost80 percent of America’s literate, educated teenagers can no longer read without an accompanyingnoise (music) in the background or a television screen flickering at the corner of their field ofperception. We know very little about the brain and how it deals with simultaneous conflicting input,but every common-sense intuition suggests we should be profoundly alarmed. This violation ofconcentration, silence, solitude goes to the very heart of our notion of literacy; this new form ofpart-reading, of part-perception against background distraction, renders impossible certain essentialacts of apprehension and concentration, let alone that most important tribute any human being canpay to a poem or a piece of prose he or she really loves, which is to learn it by heart. Not by brain, byheart; the expression is vital.Under these circumstances, the question of what future there is for the arts of reading is a real one.Ahead of us lie technical, psychic, and social transformations probably much more dramatic thanthose brought about by Gutenberg, the German inventor in printing. The Gutenberg revolution, as wenow know it, took a long time; its effects are still being debated. The information revolution willtouch every fact of composition, publication, distribution, and reading. No one in the book industrycan say with any confidence what will happen to the book as we’ve known it.

阅读理解Passage 2 I am one of the many city people who are always saying that given the choice we would prefer to live in the country away from the dirt and noise of a large city. I have managed to convince myself that it weren’t for my job I would immediately head out for the open spaces and go back to nature in some sleepy village buried in the country. But how realistic is the dream? Cities can be frightening places. The majority of the population live in massive tower blocks, noisy, dirty and impersonal. The sense of belonging to a community tends to disappear when you live fifteen floors up. All you can see from your window is sky, or other blocks of flats. Children become aggressive and nervous—cooped up at home all day, with nowhere to play; their mothers feel isolated from the rest of the worlD、 Strangely enough whereas in the past the inhabitants of one street all knew each other, nowadays people on the same floor in tower blocks don’t even say hello to each other. Country life, on the other hand, differs from this kind of isolated existence in that a sense of community generally binds the inhabitants of small villages together. People have the advantage of knowing that there is always someone to turn to when they need help. But country life has disadvantages too. While it is true that you may be among friends in a village, it is also true that you are cut off from the existing and important events that take place in cities. There’s little possibility of going to a new show or the latest movie. Shopping becomes a major problem, and for anything slightly out of the ordinary you have to go on and expedition to the nearest large town. The city-dweller who leaves for the country is often oppressed by a sense of unbearable stillness and quiet. What, then, is the answer? The country has the advantage of peace and quiet, but suffers from the disadvantage of being cut off; the city breeds a feeling of isolation, and constant noise batters the senses. But one of its main advantages is that you are at the center of things, and that life doesn’t come to an end at half-past nine at night. Some people have found (or rather bought) a compromise between the two; they have expressed their preference for the “quiet life”by leaving the suburbs and moving to villages within commuting distance of large cities. They generally have about as much sensitivity as the plastic flowers they leave behind—they are polluted with strange ideas about change and improvement which they force on to the unwilling original inhabitants of the villages. What then of my dreams of leaning on a cottage gate and murmuring “morning” to the locals as they pass by? I’m keen on the idea, but you see there’s my cat, Toby, I’m not at all sure that he would take to all that fresh air and exercise in the long grass, I mean, can you see him mixing with all those hearty males down the farm? No, he would rather have the electric imitation-coal fire any evening. We get the impression from the first paragraph that the author
