The history of responds to the work of the artist Sandro Botticelli (1444-1510) suggests that widespread appreciation by critics is a relatively recent phenomenon. Writing in 1550, Vasari expressed an unease with Botticelli's work, admitting that the artist fitted awkwardly into his evolutionary scheme of the history of art. Over the next two centuries, academic art historians defamed Botticelli in favor of his fellows Florentine, Michelangelo. Even when anti-academic art historians of the early nineteenth century rejected many of the standards of evaluation adopted by their predecessors, Botticelli's work remained outside of accepted taste, pleasing neither amateur observers nor connoisseurs. (Many of his best paintings, however, remained hidden away in obscure churches and private homes.) The primary reason for Botticelli's unpopularity is not difficult to understand: most observers, up until the mid-nineteenth century, did not consider him to be noteworthy, because his work, for the most part, did not seem to these observers to exhibit the traditional characteristics of fifteenth-century Florentine art. For example, Botticelli rarely employed the technique of strict perspective and, unlike Michelangelo, never used chiaroscuro. Another reason for Botticelli's unpopularity may have been that his attitude toward the style of classical art was very different from that of his contemporaries. Although he was thoroughly exposed to classical art, he showed little interest in borrowing from the classical style. Indeed, it is paradoxical that a painter of large-scale classical subjects adopted a style that was only slightly similar to that of classical art. In any case, when viewers began to examine more closely the relationship of Botticelli's work to the tradition of fifteenth-century Florentine art, his reputation began to grow. Analyses and assessments of Botticelli made between 1850 and 1870 by the artists of the Pre-Raphaelite movement, as well as by the writer Pater (although he, unfortunately, based his assessment on an incorrect analysis of Botticelli's personality), inspired a new appreciation of Botticelli throughout the English-speaking world. Yet Botticelli's work, especially the Sistine frescoes, did not generate worldwide attention until it was finally subjected to a comprehensive and scrupulous analysis by Home in 1908. Home rightly demonstrated that the frescoes shared important features with paintings by other fifteenth-century Florentines—features such as skillful representation of anatomical proportions, and of the human figure in motion. However, Home argued that Botticelli did not treat these qualities as ends in themselves—rather, that he emphasized clear depletion of a story, a unique achievement and one that made the traditional Florentine qualities less central. Because of Home's emphasis crucial to any study of art, the twentieth century has come to appreciate Botticelli's achievements. Which of the following would be the best title for the text?

Today's college students are more narcissistic (自恋的) and self-centered than their predecessors, according to a comprehensive new study by five psychologists who worry that the trend could be harmful to personal relationships and American society. "We need to stop endlessly repeating 'You're special' and having children repeat that back," said the study's lead author, Professor Jean Twenge of San Diego State University. "Kids are self-centered enough already." "Unfortunately, narcissism can also have very negative consequences for society, including the breakdown of close relationships with others," he said. The study asserts that narcissists "are more likely to have romantic relationships that are short-lived, at risk for infidelity, lack emotional warmth, and to exhibit game-playing, dishonesty, and over-controlling and violent behaviors." Twenge, the author of em>Generation Me: Why Today's Young Americans Are More Confident, Assertive, Entitled—and More Miserable Than Ever Before/em>, said narcissists tend to lack empathy, react aggressively to criticism and favor self-promotion over helping others. Some analysts have em>commended/em> today's young people for increased commitment to volunteer work. But Twenge viewed even this phenomenon skeptically, noting that many high schools require community service and many youths feel pressure to list such endeavors on college applications. Campbell said the narcissism upsurge seemed so pronounced (非常明显的) that he was unsure if there were obvious remedies. "Permissiveness seems to be a component," he said. "A potential antidote would be more authoritative parenting. Less indulgence might be called for." Yet students, while acknowledging some legitimacy to such findings, don't necessarily accept negative generalizations about their generation. Hanady Kader, a University of Washington senior, said she worked unpaid last summer helping resettle refugees and considers many of her peers to be civic-minded. But she is dismayed (气馁，灰心) by the competitiveness of some students who seem prematurely focused on career status. "We're encouraged a lot to be individuals and go out there and do what you want, and nobody should stand in your way," Kader said. "I can see goals and ambitions getting in the way of other things like relationships." Kari Dalane, a University of Vermont sophomore, says most of her contemporaries are politically active and not overly self-centered. "People are worried about themselves—but in the sense of where they're going to find a place in the world," she said. "People want to look their best, have a good time, but it doesn't mean they're not concerned about the rest of the world." Besides, some of the responses on the narcissism test might not be worrisome, Dalane said. "It would be more depressing if people answered, 'No, I'm not special.'" According to the passage, a narcissistic person may ______.

Humanity uses a little less than half the water available worldwide. Yet occurrences of shortages and droughts are causing famine and distress in some areas, and industrial and agricultural by-products are polluting water supplies. Since the world's population is expected to double in the next 50 years, many experts think we are on the edge of a widespread water crisis. But that doesn't have to be the outcome. Water shortages do not have to trouble the world—if we start valuing water more than we have in the past. Just as we began to appreciate petroleum more after the 1970s oil crises, today we must start looking at water from a fresh economic perspective. We can no longer afford to consider water a virtually free resource of which we can use as much as we like in any way we want. Instead, for all used except the domestic demand of the poor, governments should price water to reflect its actual value. This means charging a fee for the water itself as well as for the supply costs. Governments should also protect this resource by providing water in more economically and environmentally sound ways. For example, often the cheapest way to provide irrigation water in the dry tropics is through small-scale projects, such as gathering rainfall in depressions and pumping it to nearby cropland. No matter what steps governments take to provide water more efficiently, they must change their institutional and legal approaches to water use. Rather than spread control among hundreds or even thousands of local, regional, and national agencies that watch various aspects of water use, countries should set up central authorities to coordinate water policy. What is the real cause of the potential water crisis?

In police work

When Mark Zuckerberg posted a picture of himself on Facebook in June, a sharp-eyed observer spotted a piece of tape covering his laptop's camera. The irony didn't go unnoticed: A man whose $350 billion company relies on users feeding it intimate details about their lives is worried about his own privacy. But Zuckerberg is smart to take precautions. Many of the cameras that can be pointed at us today are easy to spot. But researchers are developing recording devices that can hide in plain sight, some by mimicking animals. A company called AeroVironment has produced a drone that looks and flies like a humming bird. Engineers at Carnegie Mellon, NASA, and elsewhere have designed "snakebots" that can maneuver in tight spaces and could be adapted for surveillance. Robotic bugs are in development, too, and engineers at UC Berkeley and in Singapore are developing cyborg beetles—real insects that can be remote-controlled via implanted electrodes and that might someday pack cameras. With the advent of the Internet of Things, appliances and gadgets will monitor many aspects of our lives, from what we eat to what we flush. Devices we talk to will record and upload our conversations, as Amazon's Echo already does. Even toys will make us vulnerable. Kids say the darndest things, and the talking Hello Barbie doll sends those things wirelessly to a third-party server, where they are analyzed by speech-recognition software and shared with vendors. Even our thoughts could become hackable. The technology company Retinad can use the sensors on virtual-reality headsets to track user's engagement. Future devices might integrate EEG electrodes to measure brain waves. In August, Berkeley engineers announced that they had produced "neural dust," implantable electrodes just a millimeter wide that can record brain activity for scientific or medical purposes. As the data collected by all the devices around us become overwhelming, we'll increasingly rely on artificial intelligence to sift through them and make decisions, says Gary T. Marx, the author of em>Windows into the Soul: Surveillance and Society in an Age of High Technology/em>. Algorithms are already used to identify potential terrorists, as well as to generate credit ratings and parole recommendations. Chicago police use an algorithm that analyzes arrest records, social networks, and other data to identify future criminals. Soon, bots will likely guide many aspects of personnel management, such as hiring and faring. The word "sharp-eyed" in the first sentence of Paragraph One surely means ______.

The republication of the poet's most recent works will certainly ______ his national reputation.
