单选题Social psychologists arc used to hearing that their experiments are a waste of time because they just prove the obvious, and tell us what we always knew. But there is a very simple and effective riposte to this accusation. The trouble with folk-wisdom (what we always knew) is that it tends to come in pairs of statements, both of which are obviously' true, but which—unfortunately—are mutually exclusive. For example, birds of a feather flock together, but what about the attraction of opposites? Experiments may not be as much fun as intuitions, but they sometimes tell us which proverbs are actually true, or (moor often) in what circumstances which apply. There is one other preconception to be removed before tackling the question of whom we like and love, whom we find attractive and make friends with: "Why bother to study an area in which we are all expert practitioners?" Well, ff you believe that, have a word with a marriage guidance counselor, a psychiatrist, or someone involved in industrial relations. Research on friendship has established a number of facts, some interesting, some even useful. Did you know that the average student has 5-6 friends, or that a friend who was previously an enemy is liked more than the one who has always been on the right side? Would you believe that physically attractive individuals are preferred as friends to those less comely, and is it fair that physically attractive defendants are less likely to be found guilty in court? Unfortunately, such tidbits don't tell us much more than the nature or the purpose of friendship. In fact, studies of friendship seem to implicate more complex factors. For example, one function friendship seems to fulfill is that it supports the image we have of ourselves, and confirms the value of the attitudes we hold. Several studies have shown that we judge them to be more like us than they (objectively) are. This suggests that we ought to choose friends who are similar to us ('birds of a feather') rather than those who would be complementary ('opposites attract'), a prediction which is supported by empirical evidence, at least so far as attitudes and beliefs are concerned. In one experiment, some developing friendships were monitored amongst first-year students living in the same hostel. It was found that similarity of attitudes (towards politics, religion, and ethics, pastimes and aesthetics) was a good predictor of what friendships would be established by the end of four months, though it had less to do with initial alliances. The difficulty of linking friendship with similarity of personality probably reflects the complexity of our personalities. This of course can explain why we may have two close friends who have little in common and indeed dislike each other. By and large, though, it looks as though we would do well to choose friends ( and spouses) who resemble us. If this were not so, computer dating agencies would have gone out of business years ago.

单选题{{B}}Passage Five{{/B}} Some modern anthropologists hold that biological evolution has shaped not only human morphology but also human behavior. The role those anthropologists ascribe to evolution is not of dictating the details of human behavior but one of imposing constraints-ways of feeling, thinking, and acting that "come naturally" in archetypal situations in any culture. Our "frailties" --emotions and motives such as rage, fear, greed, gluttony, joy, lust, love--may be a very mixed assortment, but they share at least one immediate quality: we are, as we say, "in the grip" of them. And thus they give us our sense of constraints. Unhappily, some of those frailties--our need for ever-increasing security among them--are presently maladaptive. Yet beneath the overlay of cultural detail, they, too, are said to be biological in direction, and therefore as natural to us as are out appendixes. We would need to comprehend thoroughly their adaptive origins in order to understand how badly they guide us now. And we might then begin to resist their pressure.

单选题When she ______, she could not for a moment recognize her surroundings.

单选题Scholars often seem to operate on the assumption that any analysis with a rosy outlook simply does not adequately understand the matter at hand. Ecotourism researchers have not been derelict in this regard, as the literature review earlier showed. All the researchers who have looked at Capirona's project, however, have been impressed by its grassroots nature and are optimistic about its potential as eco-development (Colvin 1994; Wesche 1993; Silver 1992). All of these researchers, however, visited the community in its early years of operation. As mentioned previously, recent, non-scholarly reports are less positive. Thus there remains some doubt as to the long-term viability of even such a model of indigenous ecotourism development as Capirona. This study originally proposed to study Capimna's project, but that community was weary of such research visits and refused a request to carry out the study there. Palo Blanco, though completing only its first year of ecotourism developmemt was chosen as an alternate site. Perhaps it should not be surprising that the prospects for ecotourism in Rio Blanco appear, as they did in Capirona quite bright. Ecotourism development efforts differ from mainstream development efforts in that, aside from start-up loans, much or all of the continuing financial support comes from tourists rather than from governments or development agencies. As a result, the two main players many ecotourism endeavor—the hosts and the guests—are driven by differing motivations. The local population hopes to improve its own lot by taking advantage of the curiosity, disposable income, and in some cases, perhaps, good intentions of ecotourists. The tourists want to "explore the natural wonders of the world," whether that be a wildebeest migration across the Serengeti or the march of leaf-cutter ants across the jungle floor (Ryan and Grasse 1991: 166). In contrast to mass tourism, ecotourism permits tourists to seek educational self-fulfillment in the form of travel, and tries to transform that activity into something that benefits the greater good—specifically, to fund environmental preservation, rural development, and even cultural survival. However, in order to satisfy everyone—tourists, environmentalists, tour operators and the local hosts—ecotourism must bring into aliganment a variety of contradictory purposes. Ecotourism promotes feelings among tourists that they are part of the solution when, in fact, the very act of flying a thousand miles or more to their destination consumes resources and pollutes the enviroment (cf. Somerville 1994). The beauty of ecotourism is that it can exploit this egotistic motivation; the flaw is that it is forever limited by it. Even a brief foray into development literature, however, shows that flawed conceptualizations are the rule, not the exception. As development, ecotourism may be no more inchoate than any other approach, and in some ways it is as progressive as any theory. For example, ecotourism twin development goals—conserving the environment and benefiting local peoples—are increasingly seen, both within and outside of tourism circles, as interdependent. Without economic development, many argue that environmental conservation is neither ethical nor sustainable (Boo 1990: 1; West and Brechin 1992: 14; Brandon and Wells 1992). Such conservation can be achieved only by providing local people with alternative income sources which do not threaten to deplete the plants and amamis within the protected zone (Brandon and Wells 1992: 557). Most research on this issue, however, assumes that the protective regulations have been established by the government or another external ageacy. In Rio Blanco, however, the people themselves are already acting to protect their land.

单选题The way people hold to the belief that a fun-filled, painfree life equals happiness actually reduces their chances of ever attaining real happiness. If fun and pleasure are equal to happiness then pain must be equal to unhappiness. But in fact, the opposite is true: more often than not things that lead to happiness involve some pain. As a result, many people avoid the very attempts that are the source of true happiness. They fear the pain inevitably brought by such things as marriage, raising children, professional achievement, religious commitment (承担的义务), self-improvement. Ask a bachelor (单身汉) why he resists marriage even though he finds dating to be less and less satisfying. If he is honest he will tell you that he is afraid of making a commitment. For commitment is in fact quite painful. The single life is filled with fun, adventure, excitement. Marriage has such moments, but they are not its most distinguishing features. Couples with infant children are lucky to get a whole night's sleep or a three-day vacation. I don't know any parent who would choose the word fun to describe raising children, But couples who decide not to have children never know the joys of watching a child grow up or of playing with a grandchild. Understanding and accepting that true happiness has nothing to do with fun is one of the most liberating realizations. It liberates time: now we can devote more hours to activities that can genuinely increase our happiness. It liberates money; buying that new car or those fancy clothes that will do nothing to increase our happiness now seems pointless. And it liberates us from envy: we now understand that all those who are always having so much fun actually may not be happy at all.

单选题How men first learnt to invent words is unknown; in other words, the origin of language is a mystery. All we really know is that men, unlike animals, somehow invented certain sound to express thoughts and feelings, actions and things, so that they could communicate with each other; and that later they agreed upon certain signs, called letters, which could be combined to represent those sounds, and which could be written down. Those sounds, whether spoken or written in letters, we call words. The power of words, then, lies in their associations—the things they bring up before our minds. Words become filled with meaning for us by experience; and the longer we live, the more certain words recall to us the glad and sad events of our past; and the more we read and learn, the more the number of words that mean something to US increases. Great writers are those who not only have great thoughts but also express these thoughts in words which appeal powerfully to our minds and emotions. This charming use of words is what we call literary style. Above all, the real poet is a master of words. He can convey his meaning in words which sing like music, and which by their position and association can move men to tears. We should therefore learn to choose our words carefully and use them accurately, or they will make our speech silly and dull.

单选题It is a wise father that knows his own child, but today a man can boost his patemal(fatherly) wisdom—or at least confirm that he's the kid's dad．All he needs to do is shell out$30 for paternity testing kit (PTK)at his local drugstore—and another$120 to get the results． More than 60,000 people have purchased the PTKs since they first become available without prescriptions last years, according to Doug Fog, chief operating officer of Identigene, which makes the over-the-counter kits．More than two dozen companies sell DNA tests directly to the public, ranging in price from a few hundred dollars to more than$2500． Among the most popular：patemity and kinship testing, which adopted children can use to find their biological relatives and 1atest rage a many passionate genealogists—and supports businesses that offer to search for a family's geographic roots． Most tests require collecting ceils by swabbing saliva in the mouth and sending it to the company for testing．All tests require a potential candidate with whom to compare DNA． But some observers are skeptical, "There is a kind of false precision being hawked by people claiming they are doing ancestry testing, "says Trey Duster,a New York University sociologist．He notes that each indivridual has many ancestors—numbering in the hundreds just a few centuries back．Yet most ancestry testing only considers a single lineage, either the Y chromosome inherited through men in a father's line or mitochondrial DNA, which a passed down only from mothers． This DNA can reveal genetic information about only one or two ancestors, even though, for example, just three generations back people also have six other great-grandparents or, four generations back, 14 other great-great-grandparents． Critics also argue that commercial genetic testing is only as good as the reference collections to which a sample is compared．Databases used by some companies don't rely on data collected svstematically but rather lump together information from different research projects．This means that a DNA database may have a lot of data from some regions and not others, SO a person's test results may differ depending on the company that processes the results．In addition, the computer programs a company uses to estimate relationships may be patented and not subject to peer review or outside evaluation．
