Reading Comprehension
Directions: Read the following passage. Choose the best answer from the four choices marked A, B, C and D for each question.

     Most people can remember a phone number for up to thirty seconds. When this short amount of time elapses, however, the numbers are erased from the memory. How did the information get there in the first place? Information that makes its way to the short term memory (STM) does so via the sensory storage area. The brain has a filter which only allows stimuli that are of immediate interest to pass on to the STM, also known as the working memory.
     There is much debate about the capacity and duration of the short term memory. The most accepted theory comes from George A. Miller, a cognitive psychologist who suggested that humans can remember approximately seven chunks of information. A chunk is defined as a meaningful unit of information, such as a word or name rather than just a letter or number. Modem theorists suggest that one can increase the capacity of the short term memory by chunking, or classifying similar information together. By organizing information, one can optimize the STM, and improve the chances of a memory being passed on to long term storage.
     When making a conscious effort to memorize something, such as information for an exam, many people engage in “rote rehearsal”. By repeating something over and over again,we are able to keep a memory alive. Unfortunately,this type of memory maintenance only succeeds if there are no interruptions. As soon as a person stops rehearsing the information, it has the tendency to disappear. When a pen and paper are not handy, you might attempt to remember a phone number by repeating it aloud.
     If the doorbell rings or the dog barks to come in before you get the opportunity to make your phone call, you will forget the number instantly. Therefore, rote rehearsal is not an efficient way to pass information from the short term to long term memory. A better way is to practice “elaborate rehearsal”. This involves assigning semantic meaning to a piece of information so that it can be filed along with other pre-existing long term memories.
     Encoding information semantically also makes it more retrievable. Retrieving information can be done by recognition or recall. Humans can recall memories that are stored in the long term memory and used often. However, if a memory seems to be forgotten, it may eventually be retrieved by prompting. The more cues a person is given (such as pictures), the more likely a memory can be retrieved. This is why multiple choice tests are often used for subjects that require a lot of memorization.

     The ups and downs of life may seem to have no predictable plan. But scientists now know there are very definite life patterns that almost all people share. Today, when we live 20 years longer than our great-grandparents, and when women mysteriously outlive men by seven years, it is clearer than ever that the game of life” is really a game of trade-offs. As we age, we trade strength for ingenuity, speed for thoroughness, and passion for reason. These exchanges may not always seem fair, but at every age, there are some advantages. So it is reassuring to note that even if you’ve passed some of your “primes”,you still have other prime years to experience in the future. Certain important primes seem to peak later in time.
     When are you healthiest? For men,from 15 to 25; for women 15 to 30. “A man is in his best shape in the decade before age 25,‘’ says New York internist Dr. Donald Tomkins. uHis muscles are firmest, his resistance to colds and infection is highest,and his body is most efficient in utilizing nutrients.” Women,for reasons scientists do not understand,get a five-year bonus. Peak health begins to decline when the body process called anabolism (cell growth) is overtaken by the opposite process, catabolism (cell death). “Cells have been dying since birth,” says Tomkins, “but in our late 20’s,they start dying faster than they are replaced.” Also, muscle is replaced with fat.
     Women also get an additional bonus of good health later in life. The figures of National Institute of Health show that the onset of such “old age” diseases as arthritis, rheumatism and heart ailments denies the generally greater fitness of women: Life expectancy for men is now 68.3; for women 75.9. U. S. aging authority William Kannel says,“Older women with low blood pressure are practically important.” However,psychologists believe that by entering the competitive job market in increasing numbers, women may eventually give up their statistical advantage.
     When are you most likely to develop mental disorder? From 30 to 35. This surprisingly narrow peak is very real. The National Institute of Mental Health (NIMH) reports that more than half of the patients in mental hospitals, male and female, are in this age group (men leading women by about 20 %).
     But if we are most neurotic between 30 and 35, apparently we recover quickly. Admissions to mental hospitals drop sharply around age 40 and stay down until age 65. Yet,say psychologists,between 40 and 55, more people report they “feel” on the verge of a nervous breakdown. Relatively few actually occur. uWe become veterans at coping,” says psychologist Marvin Karlins.

        Ever since 2003, when Lisa Belkin’s article in The Times Magazine about highly privileged and high—achieving moms — “The Opt—Out Revolution” — was generalized by the news media to claim that mothers overall were choosing to leave the work force, researchers have been revisiting the state of mothers’ employment and reaching very similar conclusions.
        In 2005, the Motherhood Project published a report that said most mothers, given free choice, would choose to be employed — provided their employment didn’t take up too much time. Approximately two—thirds said they’d ideally work part—time or from home; only 16 percent said they’d prefer to work full—time.
        Sociologist David Cotter looked carefully at four decades of employment data and found that women with choices — those with college education — were overwhelmingly choosing, to stay in the work force. The only women “opting out” in any significant numbers were the very richest and the very poorest.
        You might say that the movement of the richest women out of the work force proves that women will, in the best of all possible worlds, go home. But these women often have husbands who work 70 or 80 hours a week and travel extensively; someone has to be home. They are privileged, it’s true, but very often they have also been cornered by the all—or—nothing non—choices of our workplaces.
        The alternative narrative — of constricted horizons, not choice — that might have emerged from recent research has never really made it into the mainstream. It just can’t, it seems, find a foothold. “The reason we keep getting this narrative is that there is this deep cultural ambivalence about mothers’ employment,” said Cotter. “On the one hand, people believe women should have equal opportunities, but on the other hand, we don’t envision men taking on more child care and housework and, unlike Europe, we don’t seem to be able to envision family—friendly work policies.”
        Why this matters — and why opening this topic up for discussion is important — is very clear: because our public policy continues to rest upon a false idea, eternally recycled in the media, of mothers’ free choices, and not upon the constraints that truly drive their behavior. If journalism repeatedly frames the wrong problem, then those who make public policy may very well deliver the wrong solution. E. J. Graff, a senior researcher at Brandeis University, says, “If women are happily choosing to stay home with their babies, that’s a private decision. But it’s a public policy issue if schools, jobs and other American institutions are structured in ways that make it frustratingly difficult, and sometimes impossible, for parents to manage both their jobs and family responsibilities.”

     Engineers and scientists are working on several ways to catch the carbon, either before or after coal bums. One technology known as integrated gasification combined cycle,or IGCC,would turn the coal into gas before it’s burned for energy; gasifying it releases the carbon for capture, transportation, and sequestration deep underground. Another process,called “oxy-coal” combustion, removes nitrogen from air before combustion; when coal is burned, the waste gas is close to pure C〇2, which can be easily captured.
     Scientists and engineers hope to pump this captured carbonation through mile-long straws that reach deep into the Earth’s crust, into salt mines,aquifers and oil fields. Underground, the pressure will liquefy it and perhaps eventually turn it to rock. Think of it as “geo-bottling” - except we never want to pop the cap. From Houston to Huainan,scientists are already digging holes and pumping down C〇2 by the ton.
     Today, the C〇2 captured for producing soda is only a very small percentage of the total CO2 from power plants, but the technology for large-scale carbon capture and storage looks to be just around the comer. Spurring action from industry and governments has proved difficult, however, because the long-term economic, social and environmental costs of CO2 pollution are not included in the price we pay for energy. That makes C〇2-intensive sources of energy like coal-fired power plants look like a better deal than cleaner technologies. But the truth is,it’s a “pay me now, or pay me later” situation. In the context of climate change,it’s more like,“pay me now,or your kids will pay me even more later.”
     Fortunately, a combination of efficient markets and smart policy could level the playing field. A. carbon-storage industry will be virtually impossible without a national policy that puts a price on CO2 pollution. One such policy involves the creation of a national cap for greenhouse gas emissions and an accompanying market for tradable carbon emission credits. This summer, the U.S. Senate will likely consider legislation that would set up such a market. By making carbon a pollutant and unleashing market forces to find a price for it, the nation will essentially be revealing fossil fuel’s true social cost - and giving cleaner technologies, including carbon capture and storage, a fair shot.

     When the German cruise ship Wilhelm Gustloff was hit by torpedoes fired from a Russian submarine in the final winter of World War II, more than 10,000 people—mostly women, children and old people fleeing the final Red Army push into Nazi Germany—were packed aboard. An ice storm had turned the decks into frozen sheets that sent hundreds of families sliding into the sea as the ship tilted and began to go down. Others desperately tried to put lifeboats down. Some who succeeded fought off those in the water who had the strength to try to claw their way aboard. Most people froze immediately. “I’ll never forget the screams,” says Christa Nutzmann, 87, one of the 1,200 survivors. She recalls watching the ship, brightly lit, slipping into its dark grave—and into seeming nothingness, rarely mentioned for more than half a century.
     Now Germany’s Nobel Prize-winning author Gunter Grass has revived the memory of the 9,000 dead, including more than 4,000 children—with his latest novel Crab Walk, published last month. The book, which will be out in English next year, doesn’t dwell on the sinking; its heroine is a pregnant young woman who survives the catastrophe only to say later: “Nobody wanted to hear about it, not here in the West (of Germany) and not at all in the East." The reason was obvious. As Grass put it in a recent interview with the weekly Die Woche: “Because the crimes we Germans are responsible for were and are so dominant, we didn’t have the energy left to tell of our own sufferings.”
     The long silence about the sinking of the Wilhelm Gustloff was probably unavoidable and necessary. By unreservedly admitting to their country's monstrous crimes in the Second World War, Germans have managed to win acceptance abroad, marginalize the neo-Nazis at home and make peace with their neighbors. Today’s unified Germany is more prosperous and stable than at any time in its long, troubled history. For that, a half century of willful forgetting about painful memories like the German Titanic was perhaps a reasonable price to pay. But even the most politically correct Germans believe that they have now earned the right to discuss the full historical record. Not to equate German suffering with that of its victims, but simply to acknowledge a terrible tragedy.

        Public health experts have long been skeptical about the beneficial effect of pets on the health of their owners. After all, dogs bite and pass on parasites, and pigeons and parrots cause lung disease. However, in 1991, researchers at the University of Cambridge in Britain discovered that a short time after acquiring a cat or a dog, some people suffer less from health problems such as headache, backache and flu. It was also announced recently that Australians who keep pets tend to have less cholesterol in their blood than non-pet owners with comparable lifestyles, making them less likely to develop heart disease.
        For the time being, the findings are little more than puzzling correlations. Why should owning a pet make you less likely to suffer from backache? Why should it reduce your cholesterol level? Many researchers suspect that answers will be found in the subtle links between mental and physical well-being. If the newly discovered correlations between human health and pet ownership can be confirmed, they are likely to trigger fresh research on the psychological and physiological effects of keeping pets.
        The hint that pets could help some people to live longer came from a discovery made over a decade ago. Erica Friedmann, working at the University of Maryland in the United States, investigated whether a person's social life and degree of social isolation might influence their ability to survive a heart attack. Friedmann interviewed 92 recovering male patients and quizzed them in detail about their lifestyle, a few questions touching upon pets. A year later fourteen of the 92 men had died. Friedmann went back to her data to look for differences between those who had and those who had not survived. She found that socially isolated people were more likely to fall victim, and that those who had pets were more likely to recover.
Or the explanation is that pets can provide owners with a special kind of emotional support which is lacking or at least uncommon in relationships between people. An animal's muteness is a benefit, not a burden. The problem with language is that although we use it to communicate the deepest thoughts and emotions, we also use it to deceive, misinform, criticize and insult others. The fact that pets listen and seem to understand, but do not question or evaluate, may be one of their most endearing assets as companions. It resembles the relationships some psychotherapists try to build.

        Concern about individual privacy on the Internet has been rising. E-commerce continues to grow, but many online shoppers are concerned about how their personal information is being or might be used. According to a Harris poll, many people do not shop online because of this concern, and of those who do shop online, 41% say they are very concerned about how a company uses their personal information. Now a clear majority of Americans - 57% - favor some sort of laws regulating how personal information is collected and used. Just as people are angry at intrusions into their physical space, they now want to protect the privacy of their virtual space.
        For most companies, the Web can be a vast source of information about customers. Each buying that a user conducts on a Web site, from a single click to an actual online purchase, can be stored and analyzed. A company can learn about visitors to its Web site through “cookies”, which are small data files that the site creates on the first visit and stores in the user's computer. A cookie contains a unique tracking number, which enables sites to “remember” users on all subsequent visits. When you visit a site, it places electronic bits of data in your computer that tell the site a lot about you: what your e-mail address is, which portions of a Web site you looked at, what purchases you made, and so on. Many people do not even know that these “cookies” are being placed into their computers. Privacy advocates point out that if Web profiles ever became available for sale on the open market, such information could be used against people. For example, someone might not be hired for a future job if it became known that he or she had sought certain health advice on the Web. Or let's say a customer has purchased a lot of ice cream and wine on the Web. An insurance company could use that information against the person, assuming he or she would be a candidate for high cholesterol or alcoholism, and refuse to provide insurance.

        When trying to understand why some people have trouble living within their means, we tend to blame factors such as high interest rates and irresponsible spending. Now researchers have found another possible factor to add to the list: a gene linked to credit-card debt.
        Earlier work has shown that genetics plays a role in how we handle money. But a recent study was the first to show that a particular gene affects financial behavior outside the lab. Researchers at the University of California, San Diego, and the London School of Economics looked at genetic data and questionnaires already collected from more than 2,000 young adults aged 18 to 26 as part of the National Longitudinal Study of Adolescent Health. In particular, they looked at whether these young adults said they had any credit-card debt and what version of the MAOA gene they had.
        Monoamine oxidase A (MAOA) (甲型单胺氧化酶) is an enzyme that breaks down the signaling chemicals called neuro-transmitters in the brain. Previous studies have linked the low-efficiency versions of the MAOA gene - the variants that cause less MAOA to be produced by brain cells - to impulsiveness.
        In the new study, people with one “low” MAOA gene and one “high” MAOA gene reported having credit-card debt 7.8 percent more often than did people with two “high” versions, the researchers found, even when they controlled for factors such as education and socioeconomic status. For people with two “low” versions of the gene, that number jumped to 15.9 percent.
        The researchers were surprised by the magnitude of the difference. “The effect is almost as big as financial literacy,” meaning people's ability to digest complicated financial information, says Jan-Emmanuel de Neve, an author of the study.
        But, de Neve cautions, an individual's version of the MAOA gene does not predict whether he or she is carrying debt. The gene affects credit-card debt the way other genes have been found to play a role in breast cancer: a particular version of the gene increases risk, but many other genetic and environmental factors are important, too.

        For some time past it has been widely accepted that babies - and other creatures - learn to do things because certain acts lead to “rewards”; and there is no reason to doubt that this is true. But it used also to be widely believed that effective reward, at least in the early stages, had to be directly related to such basic physiological “drives” as thirst or hunger. In other words, a baby would learn if he got food or drink or some sort of physical comfort, not otherwise.
        It is now clear that this is not so. Babies will learn to behave in ways that produce results in the world with no reward except the successful outcome.
        Pap began his studies by using milk in the normal way to “reward” the babies and so teach them to carry out some simple movements, such as turning the head to one side or the other. Then he noticed that a baby who had enough to drink would refuse the milk but would still go on making the learned response with clear signs of pleasure. So he began to study the children's responses in situations where no milk was provided. He quickly found that children as young as four months would learn to turn their heads to right or left if the movement “switched on” a display of lights - and indeed that they were capable of learning quite complex turns to bring about this result, for instance, two left or two right, or even to make as many as three turns to one side.
        Pap's light display was placed directly in front of the babies and he made the interesting observation that sometimes they would not turn back to watch the lights closely although they would “smile and bubble” when the display came on. Pap concluded that it was not primarily the sight of the lights which pleased them, it was the success they were achieving in solving the problem, in mastering the skill, and that there exists a fundamental human urge to make sense of the world and bring it under intentional control.

Passage Two 
    Any discussion of English conversation, like any English conversation, must begin with The Weather. And in this spirit of observing traditional protocol, I shall quote Dr. Johnson’s famous comment that “When two English meet, their first talk is of the weather”, and point out that this observation is as accurate now as it was over two hundred years ago. 
    This, however, is the point at which most commentators either stop, or try, and fail, to come up with a convincing explanation for the English “obsession” with the weather. They fail because their premise is mistaken: they assume that our conversations about the weather are conversations about the weather. In other words, they assume that we talk about the weather because we have a keen interest in the subject. Most of them then try to figure out what it is about the English weather that is so fascinating. 
    Bill Bryson, for example, concludes that the English weather is not at all fascinating, and presumably that our obsession with it is therefore inexplicable: “To an outsider, the most striking thing about the English weather is that there is not very much of it. All those phenomena that elsewhere give nature an edge of excitement, unpredictability and danger - tornados, monsoons, hailstorms – are almost wholly unknown in the British Isles.” 
    Jeremy Paxman takes offence at Bryson’s dismissive comments and argues that the English weather is intrinsically fascinating: 
    Bryson misses the point. The interest is less in the phenomena themselves, but in uncertainty… one of the few things you can say about England with absolute certainty is that it has a lot of weather. It may not include tropical cyclones but life at the edge of an ocean and the edge of a continent means you can never be entirely sure what you’re going to get. 
    My research has convinced me that both Bryson and Paxman are missing the point, which is that our conversations about the weather are not really about the weather at all: English weather-speak is a form of code, evolved to help us overcome our natural reserve and actually talk to each other. Everyone knows, for example, that “Nice day, isn’t it?”, “Ooh, isn’t it cold?”; and other variations on the theme are not requests for meteorological data: they are ritual greetings or conversation-starters. In other words, English weather-speak is a form of “grooming talk” - the human equivalent of what is known as “social grooming” among our primate cousins, where they spend hours grooming each other’s fur, even when they are perfectly clean, as a means of social bonding.

    On a hot summer’s day many years ago, I was on my way to pick up two items at the supermarket. I was then a frequent visitor to it because there never seemed to be enough money for a whole week’s food-shopping at once. 
    My wife, after a tragic battle with cancer, had died just a few months earlier. There was no insurance -just many expenses and a mountain of bills. I held a part-time job, which barely generated enough money to feed my two young children. Things were really bad. 
    And so, with a heavy heart and four dollars in my pocket, I was on my way to the supermarket to purchase a gallon of milk and a loaf of bread. The children were hungry and I had to get them something to eat. As I came to a red traffic light, I noticed on my right a young couple and a child on the grass next to the road. The noonday sun beat down on them without mercy.
    The man held up a sign which read, “Will Work for Food.” The woman stood next to him, staring at the cars stopped at the red light. The child sat on the grass holding a one-armed doll. I noticed all this before the light changed to green. 
    I wanted so desperately to give them a few dollars, but if I did that, there wouldn’t be enough left to buy the food for my kids. Four dollars will only go so far. As the light changed, I took one last glance at them and sped off feeling both guilty and sad. 
    As I kept driving, I couldn’t get the picture of them out of my mind. The sad, haunting eyes of the young couple stayed with me for about a mile. I could take it no longer. I felt their pain and had to do something about it. I turned around and drove back to where I had last seen them. 
    I pulled up close to them and handed the man two of my four dollars. There were tears in his eyes as he thanked me. I smiled and drove on to the supermarket. Perhaps both milk and bread would be on sale, I thought. And what if I only got milk alone, or just the bread? Well, it would have to do.

Passage One 
    Young girls and women need to be protected from inducements to smoke. Tobacco is a multinational, multi-billion dollar industry. It is also an industry under threat; one quarter of its customers, in the long-term, have been killed by using its product and smoking is declining in many industrialized countries. To maintain profits, tobacco companies need to ensure that at least 2.7 million new smokers, usually young people, start smoking every year. Women have been clearly identified as a key target group for tobacco advertising in both the industrialized and developing worlds. Billions of US dollars each year are spent on promoting this lethal product specifically to women. 
    This strategy has been highlighted by several tobacco journals which have carried articles on “targeting the female smokers” and suggesting that retailers should “look to the ladies”. Among 20 US magazines that received the most cigarette advertising revenue in 1985, eight were women’s magazines. In the same year, a study on the cigarette advertising policies of 53 British women’s magazines showed that 64 percent of the magazines accepted cigarette advertising, which represented an average of seven percent of total advertising revenue. 
    Research in industrialized countries has shown the subtle method used to encourage girls to smoke. The impact of such method is likely to be even greater in developing countries, where young people are generally less knowledgeable about smoking hazards and may be more attracted by glamorous, affluent, desirable images of the female smoker. This is why World Health Organization (WHO), together with other national and international health agencies, has repeatedly called for national legislation banning all forms of tobacco promotion, and for an appropriate “high price” policy which would slow down the “enthusiasm” of young women for tobacco consumption. 
    Young girls and women have a right to be informed about the damage that smoking can do to their health. They also need to acquire skills to resist pressure to start smoking or to give it up. Several countries have developed integrated school health education programs which have successfully reduced girls’ smoking rates, but this education should not be restricted to what happens in school. There are many other examples of effective cessation programs in the workplace and primary health centers. Unfortunately, many women do not have the opportunity to be involved in such programs, and programs have generally been less successful with women than with men. 
    In order for women to become, and remain, non-smokers they need support. Environments need to be created which enable them to break free of this health damaging behavior, to make the healthy choices the best choices.

        Toward twelve o'clock, when we were crossing a high land, we heard the cry of a young animal, which we all recognized to be a baby ape. We crawled through the bush as silently as possible, still hearing the baby-like cry. Then a frightened little ape came into our sight. I could not tell my surprise when I saw that the baby ape's face was pure white - very white indeed - pallid. The little one was about a foot in height. One of the men threw cloth over its head and we secured it with a rope.
        I called him Tommy, to which name he soon began to answer. He had a great affection for me, and used constantly to follow me about. When I sat down, he was not content till he had climbed upon me and hid his head in my breast. He was extremely fond of being petted and fondled and would sit for hours while any one stroked his head or back.
        He soon began to be a great thief. When the people left their huts he would steal in and make off with their plantains or fish. He watched very carefully till all had left the house, and it was difficult to catch him in the act.
        From me he stole constantly. He soon found out that my hut was better furnished with ripe bananas and other fruit than any other; and also he discovered that the best time to steal from me was when I was asleep in the morning. At that time he used to crawl in on his tiptoes, move slyly toward my bed, look at my closed eyes, and, if he saw no movement, with an air of great relief go up and pluck several plantains. If I stirred in the least he was off like a flash, and would presently reenter for another inspection. If my eyes were open when he came in on such a predatory trip, he at once came up to me with an honest face, and climbed on and caressed me. But I could easily detect an occasional wishful glance toward the bunch of plantains.
        He kept the run of mealtimes, and was present at as many meals as possible; that is, he would go from my breakfast to half a dozen others, and beg something at each. He was very fond of boiled meat - particularly boiled fish - and was constantly picking bones. He wanted always to taste my coffee, and would beg of me, in the most serious manner, for some.
        Tommy had a great deal of intelligence; and if I had had leisure I think I might have trained him to some kind of good behavior, though I despaired of his thieving disposition. He lived so long, and was growing so accustomed to civilized life, that I began to have great hopes of being able to carry him to America. But, one morning he refused his food, seemed downcast, and was very anxious to be petted and held in the arms. I got all kinds of forest berries for him, but he refused all. He did not seem to suffer, but ate nothing; and the next day, without a struggle, died. I was very sorry, for he had grown to be quite a pet companion for me.

    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.

    Modern humans emerged some 250,000 years ago, yet agriculture is a fairly recent invention, only about 10,000 years old. Many crop plants are rather new additions to our diet: broccoli (a flowering mutant of kale) is thought to be only 500 years old. Most innovation is far more recent still. Although Austrian monk Gregor Mendel’s pea plant experiments quietly laid the basic foundations of genetics in the mid-19th century, his work was rediscovered and applied to crop breeding only at the beginning of the 20th century. 
    Further advances have steadily accumulated. The 1940s saw the identification of DNA as genetic material and the adoption, by commercial breeders, of genetic modification - typically by applying chemicals or radiation to DNA to try to make plants with advantageous characteristics. The modifications ultimately led to the green revolution of the 1960s and 1970s, during which time global wheat yields tripled. The 1980s and 1990s saw the commercial adoption of agricultural biotechnology, which has allowed breeders to introduce specific genes into crops from the same or different species. In 2004 the first plant genome was fully sequenced, and since then the number of plant gene sequences in GenBank, the public repository for gene sequence information, has been doubling every two years. Our knowledge is increasing exponentially, as it has been in other fields such as semiconductors and cellular telephony. 
    Our challenge is to increase agricultural yields while decreasing the use of fertilizer, water, fossil fuels and other negative environmental inputs. Embracing human ingenuity and innovation seems the most likely path. Plants did not evolve to serve humans, and their sets of genes are incomplete for our purposes. The integral role of modifying genes is obvious to all breeders, though sometimes painfully absent from the public’s understanding of how modern agriculture succeeds. All breeding techniques, from before Mendel’s time until today, exploit modifications to plant DNA. These modifications can take the form of mistakes or mutations that occur during natural cell division in the wild; the natural but random movement of DNA sequences from one part of a plant’s genome to another; or the more precise insertion of known gene sequences using biotechnology. In all these cases, plant genes are moved within or across species, creating novel combinations. Hybrid genetics - the combination of different versions of the same gene – has resulted in spectacular yield increases. Largely as the consequence of using hybrid seed varieties, corn yields in the U.S. have increased more than 500 percent in the past 70 years.

        If you've ever been pranked on April Fools' Day, you may wonder how this tradition started. Well, you're not alone. No one knows for sure how April Fools' Day began. But the most likely explanation has to do with the calendar.
        No, that's not an April Fools' Day joke. People used to celebrate New Year's Day on April lst. Just like today, people would have big parties to celebrate. Over time, the calendar changed and so did the date for New Year's. In the 1500s, the new calendar marked New Year's Day as January lst. But because there was no Internet or other means to spread the word, the news traveled slowly by word of mouth. It took a while for everyone to hear about the change, and even then some people resisted it. They continued to celebrate New Year's on April lst. These people were given the nickname“April fools”.
        People following; the new calendar played tricks on the “April fools” by sending them on“ fool's errands”. They had the “April fools” deliver invitations to big New Year's celebrations that weren't really going to happen. In France, “April fools” were called “Poisson d'Avril”, which is French for “April Fish”. This began because people thought fish were easy to catch since they could be fooled into taking the bait on a hook. Children would tag a paper fish on a person's back to mark them as an “April Fish”. When the person discovered the fish, the prankster would yell “Poisson d'Avril”.
        Not everyone is convinced that this is actually how the tradition of April Fools'Day began.  People have tried to pinpoint the exact date of the first April Fools' Day, but this only led to more pranks. A professor from Boston University pranked a reporter by making up a story about a court jester who said he could run the empire better than the king. The jester was made king for a day on April 1st. This turned out to be a big April Fools' Day trick because the reporter thought the story was real.
        Even though we aren't sure how this tradition began, people still celebrate April Fools' Day by playing tricks on each other. So the next time you prank someone and yell “April Fools!” remember that the day may actually be about the people who didn't want to change their traditions when the new calendar was adopted. Or maybe it's just a day to celebrate the joker in all of us.

      Nowadays there is a remarkable consensus among educators and business and policy leaders on one key conclusion: we need to bring what we teach and how we teach into the 21st century. Right now we're aiming too low. Competency in reading and math — the focus of so much No Child Left Behind (NCLB) testing – is the meager minimum. Scientific and technical skills are, likewise: utterly necessary but insufficient. Today's economy demands not only a high-level competence in the traditional academic disciplines but also what might be called 21st century skills. Here's what they are:
      Knowing more about the world. Kids are global citizens now, even in small-town America, and they must learn to act that way. Mike Eskew, CEO of UPS, talks about needing workers who are "global trade literate, sensitive to foreign cultures, conversant in different languages” — not exactly strong points in the U.S., where fewer than half of high school students are enrolled in a foreign-language class and where the social-studies curriculum tends to fixate on U.S. history.
      Thinking outside the box. Jobs in the new economy — the ones that won't get outsourced or automated – “put an enormous premium on creative and innovative skills, seeing patterns where other people see only chaos,” says Marc Tucker, an author of the skills-commission report and president of the National Center on Education and the Economy. Traditionally that's been an American strength, but schools have become less daring in the back-to-basics climate of NCLB. Kids also must learn to think across disciplines, since that's where most new breakthroughs are made. It's interdisciplinary combinations — design and technology, mathematics and art – “that produce YouTube and Google,” says Thomas Friedman, the best-selling author of The World Is Flat.
     Becoming smarter about new sources of information. In an age of overflowing information and proliferating media, kids need to rapidly process what's coming at them and distinguish between what's reliable and what isn't. “It's important that students know how to manage it, interpret it, validate it, and how to act on it,” says Dell executive Karen Bruett, who serves on the board of the Partnership for 21st Century Skills, a group of corporate and education leaders focused on upgrading American education.
      Developing good people skills. EQ, or emotional intelligence, is as important as IQ for success in today's work place. "Most innovations today involve large teams of people,” says former Lockheed Martin CEO Norman Augustine. “We have to emphasize communication skills, the ability to work in teams and with people from different cultures.”

          There are many different kinds of evidence that women and men are judged differently even if they talk the same way. This tendency makes mischief in discussions of women, men and power. If a linguistic strategy is used by a woman, it is seen as powerless; if it is used by a man, it is seen as powerful. Often, the labeling of “women’s language” as “powerless language” reflects the view of women’s behavior through the lens of men’s. 

            Because they are not struggling to be one-up, women often find themselves framed as one-down. Any situation is ripe for misinterpretation because status and connections are displayed by the same moves. This ambiguity accounts for much misinterpretation by experts as well as nonexperts, by which women’s ways of talking, uttered in a spirit of rapport are branded powerless. Nowhere is this inherent ambiguity clearer than in a brief comment in a newspaper article in which a couple, both psychologists, were jointly interviewed. The journalist asked them the meaning of “being very polite”. The two experts responded simultaneously, giving different answers. The man said, “Subservience.” The woman said, “Sensitivity.” Both experts were right, but each was describing the view of a different gender.
              Experts and nonexperts alike tend to see anything women do as evidence of powerlessness. The same newspaper article quotes another psychologist as saying, “A man might ask a woman, ‘Will you please go to the store?’ where a woman might say. ‘Gee. I really need a few things from the store, but I’m so tired. ’” The woman’s style is called “covert” a term suggesting negative qualities like being “sneaky” and “underhanded”. The reasons offered for this is power: The woman doesn’t feel she has a right to ask directly.
             Granted, women have lower status than men in our American society. But this is not necessarily why they prefer not to make outright demands. The explanation for a woman’s indirectness could just as well be her seeking connection. If you get your way as a result of having demanded it, the payoff is satisfying in terms of status: You’re one-up because others are doing as you told them. But if you get your way because others happened to want the same thing, or because they offered freely, the payoff is rapport. You’re neither one-up nor one-down but happily connected to others whose wants are the same as yours. Furthermore, if directness is understood by both parties, then there is nothing covert about it: That a request is being made is clear. Calling an indirect communication covert reflects the view of someone for whom the direct style seems “natural” and “logical” - a view more common among men.

          Snazzy technology is a twist in a narrative already several chapters long. Mass-market retailing has changed the publishing industry: these days books are as likely to be found beside steaks and saucepans as they are to be bought in specialist stores. The story turns on whether broader changes in bookselling will stifle literature. Dan Brown will survive. Would Dante? 

          For most of the past century, governments across Europe protected book prices; many still do. Even in America, apart from dime-store romances, few titles were sold outside bookshops. But in the 1970s stores like Borders and Barnes & Noble applied a supermarket maxim to print: pile them high and watch them fly. Waterstones did the same thing in Britain and top titles started selling in the hundreds of thousands, even millions.
          Just as book superstores forced out many independents, so supermarkets and other mass retailers have since crowded the book chains. In Britain, when price regulation was disbanded in 1997, supermarkets rushed in and now sell a quarter of all books, according to the way that Nielsen, a market-research outfit, calculates it. Belgium and Finland mimicked this trend.
         This has been good for readers: in Britain the average price of a book has fallen by 15% since 2003, reckons BML Bowker, a book-marketing consultancy. And demand has grown: consumers spend the same amount on books, so they must be buying more. Those independent bookshops that survived the chain war in America and Britain have held sales and prices steady. Meanwhile, mass retailers find books such a draw that they lure in customers by selling some titles at a loss.
         Higher turnover should also be positive for publishers. But mass retailers demand discounts of up to 60% for bulk orders, shrinking margins. All sides prosper when books sell quickly. But, unlike groceries, if books don’t sell, retailers return them to the publisher - and do not pay. So, when a book with a large print run flops, publishers end up with an expensive pile of recycling. That is why some publishers have stopped doing new deals with the likes of Costco, an American warehouse retailer, which likes to order very large print runs.
           Few people will mourn publishers’ losses from increased price competition and new technology like e-readers. The question is whether these trends undermine the quality of books which are being published, by breaking a business model that has let firms focus on variety and range. Publishers have good reason to shiver at the decline of traditional bookshops. To fund the discovery and promotion of new authors, they have relied on books that sell steadily over a number of years. Yet mass retailers stock a few hundred new blockbusters.

    From time to time, we need an expert. In such situations, the Internet has been like a gift from the gods. In the old days, authorities were near at hand for expert advice: the village seamstress on how to make a buttonhole, the blacksmith on how to take care of a horse's hooves, or the apothecary on what to do about warts. On the Internet, advice and answer sites are popping up all over the place, with self-proclaimed experts at the ready.
    Exp.com claims to have “tens of thousands of experts who can help you,”while the more restrained Abuzz.com, owned by The New York Times, limits its pitch to “Ask Anything! Real People. Real Answers.” It's said that expert sites or knowledge networks represent the latest stage in the Internet's evolution, a “democratization of expertise.” However, if your question is about something other than “Who invented the light bulb?”, the answers are likely to be a wild potpourri of personal opinions.
    Top colleges and universities are rushing into online education, but the big news is the proliferation of a new breed of for-profit online institutions bringing Internet education to the masses. “The Internet will probably be the single most democratizing force in education,” says Columbia Business School Dean Meyer Feldberg, who envisions educational programs being routed through the net to hundreds of millions of people.
     The largest online institution is the University of Phoenix, with some 6,000 students today and hopes of reaching 200,000 students in 10 years. The university offers bachelor's, master's, and doctoral degrees in business management, technology, education, and nursing. The university notes that its degree programs cost far less and may take some students far less time to complete.
    On the other hand, a Business Week survey of 247 companies found that only a handful would consider hiring applicants who earned their MBA degrees online.Whether that will change as for-profit online universities improve their offerings and graduates prove their worth-is anyone's guess.
     The rest of the world is moving into cyberspace more slowly than the United States, and, in the developing world, the Internet has hardly penetrated at all. UN Secretary-General Kofi Annan is determined to change this through the United Nations Information Technology Service, which will train large numbers of people to tap into the income enhancing power of the Internet. Annan is also proposing an Internet health network that will provide state-of-the-art medical knowledge to 10,000 clinics and hospitals in poor countries.
