单选题Behaviors that we do not understand often become nearly invisible—even when, in retrospect, we see how truly strange they are. When I was a psychiatric resident, we had a faculty member who was famous for his messy office: stacks of papers and old journals covered every chair and table as well as much of the floor. One day, as I walked past the open office door with one of my supervisors, he murmured mildly, "Odd duck." And that was as far as anyone seemed to reflect on this peculiar state of affairs within an institution staffed by psychiatrists. Eventually, the faculty member had to be given another office in which to see patients. Not surprisingly, the psychiatric diagnostic manual does not list "messy room" in the index. But it does mention a tantalizing symptom: inability "to discard worn-out or worthless objects even when they have no sentimental value," It comes under the diagnosis obsessive-compulsive personality disorder, an obscure cousin of the more famous obsessive compulsive disorder. I was barely aware of the diagnosis. Every era has mental disorders that for cultural or scientific reasons become popular. In Freud's day it was hysteria. Currently, depression has moved to center stage. But other ailments go relatively ignored, and this disorder was one. It came with a list of additional symptoms that appeared to be peculiar : anxiety about spending money, excessive devotion to work to the exclusion of leisure activities, rigidity about following rules, perfectionism in doing tasks—at times to the point of interfering with finishing them. In moderation, the symptoms seemed to fit right in with our workaholic culture—perhaps explaining the low profile of the diagnosis. Relentless work orientation and perfectionism may even be assets in rule-and detail-oriented professions like accounting or law. But when the symptoms are too intense or pervasive, they become crippling. Beneath the seemingly adaptive behaviors lies a central disability. People with this diagnosis have enormous difficulty making decisions. They lack the internal sense of completion that most of us experience at the end of a choice or a task, even one as simple as throwing something out or making a purchase. In obsessive-compulsive personality disorder, this feeling occurs only after endless deliberation and revision, if at all. The need to come up with the "correct" answer, the best purchase or the perfect proposal leads to excess rumination over each decision. It can even lead to complete paralysis. For such people, rules of all kinds are a godsend—they represent pre-made decisions. Open-ended assignments, like writing papers, are nightmares. For such a patient or for a psychiatrist, understanding a cluster of diagnostic symptoms can be a revelation. The picture leaps out from the previously disorganized background. But undoubtedly, at times we can become too reductionistic, seeing patterns where none exist, sometimes a messy room is just a messy room.

In addition to redistributing incomes, inflation may affect the total real income and production of the community. An increase in prices is usually associated with high employment. In moderate inflation, industries are operating efficiently and output is near capacity. There is a great deal of private investment and jobs are plentiful. Such has been the historical pattern. Thus many business persons and union leaders, in evaluating a little deflation and a little inflation, consider the latter to be the lesser of two evils. In mild inflation, the losses to fixed-income groups are usually less than gains to the rest of the community. Even worker with relatively fixed wages are often better off because of improved employment opportunities and greater take-home pay, a rise in interest rates on new securities may partly compensate for any losses to creditor, and increases in pension benefits may partly make losses to retirees. In deflation, on the other hand, the growing unemployment of labor and capital causes the community's total well-being to be less; so in a sense, the gainers get less than the losers lose. As a matter of fact, in a depression, or a time of severe deflation, almost everyone suffers, including the creditor who is left with uncollectible debts. For these reasons as increase in consumption of investment spending is considered good in times of unemployment, even if this tends to increase prices slightly. When the economic system is suffering from severe depression, few people will criticize private or public spending on the ground that this might be inflationary. Actually, most of this increased spending will increase production and create jobs. once, full employment and full plant capacity have been reached, however, any further increases in spending are likely to be completely wasted in prices increase.

单选题If you happened to be watching NBC on the first Sunday morning in August last summer, you would have seen something curious. There, on the set of Meet the Press, the host, David Gregory, was interviewing a guest who made a forceful case that the U. S. economy had become "very distorted. " In the wake of the recession, this guest explained, high-income individuals, large banks, and major corporations had experienced a "significant recovery"; the rest of the economy, by contrast—including small businesses and "a very significant amount of the labor force" —was stuck and still struggling. What we were seeing, he argued, was not a single economy at all, but rather "fundamentally two separate types of economy," increasingly distinct and divergent. This diagnosis, though alarming, was hardly unique, drawing attention to the divide between the wealthy and everyone else has long been standard fare on the left. (The idea of "two Americas" was a central theme of John Edwards's 2004 and 2008 presidential runs. ) What made the argument striking in this instance was that it was being offered by none other than the former five-term Federal Reserve Chairman Alan Greenspan. iconic libertarian, preeminent defender of the free market, and (at least until recently) the nation's foremost devotee of Ayn Rand. When the high priest of capitalism himself is declaring the growth in economic inequality a national crisis, something has gone very, very wrong. This widening gap between the rich and non-rich has been evident for years. In a 2005 report to investors, for instance, three analysts at Citigroup advised that "the World is dividing into two blocs—the Plutonomy and the rest". In a plutonomy there is no such animal as "the U.S. consumer" or "the UK consumer", or indeed "the Russian consumer". There are rich consumers, few in number, but disproportionate in the gigantic slice of income and consumption they take. There are the rest, the "non-rich", the multitudinous many, but only accounting for surprisingly small bites of the national pie. Before the recession, it was relatively easy to ignore this concentration of wealth among an elite few. The wondrous inventions of the modern economy—Google, Amazon, the iPhone broadly improved the lives of middle-class consumers, even as they made a tiny subset of entrepreneurs hugely wealthy. And the less-wondrous inventions—particularly the explosion of subprime credit—helped mask the rise of income inequality for many of those whose earnings were stagnant. But the financial crisis and its long, dismal aftermath have changed all that. A multibillion-dollar bailout and Wall Street's swift, subsequent reinstatement of gargantuan bonuses have inspired a narrative of parasitic bankers and other elites rigging the game for their own benefit. And this, in turn, has led to wider-and not unreasonable-fears that we are living in not merely a plutonomy, but a plutocracy, in which the rich display outsize political influence, narrowly self-interested motives, and a casual indifference to anyone outside their own rarefied economic bubble.

单选题4 The evolution of sex ratios has produced, in most plants and animals with separate sexes, approximately equal numbers of males and females. Why should this be so? Two main kinds of answers have been offered. One is couched in terms of advantage to popula tion. It is argued that the sex ratio will evolve so as to maximize the number of meetings be tween individuals of the opposite sex. This is essentially a "group selection" argu- ment. The other, and in my view correct, type of answer was first put forward by Fisher in 1930. This "genetic" argument starts from the assumption that genes can influence the relative numbers of male and female offspring produced by an individual carrying the genes. That sex ratio will be favored which maximizes the number of descendants an indi vidual will have and hence the number of gene copies transmitted. Suppose that the popula tion consisted mostly of females, then an individual who produced sons only would have more grandchildren. In contrast, if the population consisted mostly of males, it would pay to have daughters. If, however, the population consisted of equal numbers of males and females, sons and daughters would be equally valuable. Thus a one-to-one sex ratio is the only stable ratio; it is an "evolutionarily stable strategy. " Although Fisher wrote before the mathematical theory of games had been developed, his theory incorporates the essen tial feature of a game that the best strategy to adopt depends on what others are doing. Since Fisher's time, it has been realized that genes can sometimes influence the chro mosome or gamete in which they find themselves so that the gamete will be more likely to participate in fertilization. If such a gene occurs on a sex-determining (X or Y) chromo some, then highly aberrant sex ratios can occur. But more immediately relevant to game theory are the sex ratios in certain parasitic wasp species that have a large excess of fe males. In these species, fertilized eggs develop into females and unfertilized eggs into males. A female stores sperm and can determine the sex of each egg she lays by fertilizing it or leaving it unfertilized. By Fisher's argument, it should still pay a female to produce equal numbers of sons and daughters. Hamilton, noting that the eggs develop within their host--the larva of another insect--and that the newly emerged adult wasps mate immedi ately and disperse, offered a remarkably cogent analysis. Since only one female usually eggs in a given larva, it would pay her to produce one male only, because this one could fertilize all his sisters on emergence. Like Fisher, Hamilton looked for an evolutionarily stable strategy, but he went a step further in recognizing that he was looking for a strate gy.

单选题{{B}}Text 3{{/B}} Culture is the total sum of all the traditions, customs, belief and ways of life of a given group of human beings. In this sense, every group has a culture, however savage, undeveloped, or uncivilized it may seem to us. To the professional anthropologist, there is no intrinsic superiority of one culture ever another, just as to the professional linguist there is no intrinsic hierarchy among languages. People once thought of the languages of backward groups as savage, undeveloped forms of speech, consisting largely of grants and groans. While it is possible that language in ganeral began as a series of grunts and groans, it is a fact established by the study of "backward" languages that no spoken tongue answers that description today. Most languages of uncivilized groups are, by our most severe standards, extremely complex, delicate, and ingenious pieces of machinery for the transfer of ideas. They fall behind the Western languages not in their sound patterns or grammatical structures, which usually are fully adequate for all language needs, but only in their vocabularies, which reflect the objects and activities known to their speakers. Even in this department, however, two things are to be noted: 1. All languages seem to possess the machinery for vocabulary expansion, either by putting together words already in existence or by borrowing them from other languages and adapting them to their own system. 2. The objects and activities requiring names and distinctions in "backward" languages, while different from oars, are often surprisingly numerous and complicated. A western language distinguishes merely between two degrees of remoteness ("this" and "that"); some languages of the American Indians distinguish between what is close to the speaker, or the person addressed, or remote from both, or out of sight, or in the past, or in the future. This study of language, in turn, casts a new light upon the claim of the anthropologists that all cultures are to be viewed independently, and without ideas of rank or hierarchy.
