[单选题]Passage 1 Plants and animals that have been studied carefully seem to have built-in clocks. These biological clocks, as they are called, usually are not quite exact in measuring time. However, they work pretty well because they are "reset" each day, when the sun comes up. Do pigeons use their biological clocks to help them find directions from the sun? We can keep pigeons in a room lit only by lamps. And we can program the lighting to produce artificial "days",different from the day outside. After a while we have shifted their clocks. Now we take them far away from home and let them go on a sunny day. Most of thegn start out as if they know just which way to go, but choose a wrong direction. They have picked a direction that would be correct for the position of the sun and the time of day according to their shifted clocks. It is known and experimented that homing pigeons can tell directions by the sun. But what happens when the sky is darkly overcast by clouds and no one can see where the sun is? Then the pigeons still find their way home. The salne experiment has been repeated many times on sunny days and the result was always the same. But on very overcast days clock-shifted pigeons are just as good as normal pigeons in starting out in the right directions. So it seems that pigeons also have some extra sense of direction to use when they cannot see the sun. Naturally, people have wondered whether pigeons might have a built-in compass—something that would tell them about the directions of the earth's magnetic field. One way to test that idea would be to see if a pigeon's sense of direction can be fooled by a magnet attached to its back. With a strong magnet close by, a compass can no longer tell direction. To test the idea, a group of ten pigeons had strong little magnet bars attached to their backs. Another group carried brass bars instead which were not magnetic. In a number of experiments,both groups were taken away from home and let go. On sunny days none of the magnet-pigeons was fooled. They were just as good as the brass-pigeons in starting out in the right direction toward home. On cloudy, overcast days, however, with no sun the brass-pigeons chose the right direction,but the magnet-pigeons were in trouble. They later started out in different directions and acted completely lost. Which of the following can best describe the organization of the passage? 查看材料
A.Questions are raised first and then experiments to answer them are cited.
B.Opinions are given first and then evidences against them are quoted.
C.Statements come first and examples supporting them follow.
D.People's long held beliefs are cited first and exceptions come after.

[单选题]Passage 2 Scientists have been surprised at how deeply culture--the language we speak, the values weabsorb--shapes the brain, and are rethinking findings derived from studies of Westerners. To takeone recent example, a region behind the forehead called the medial prefrontal cortex supposedlyrepresents the self: it is active when we ( "we" being the Americans in the study) think of our ownidentity and traits. But with Chinese volunteers, the results were strikingly different. The "me"circuit hummed not only when they thought whether a particular adjective described themselves, butalso when they considered whether it described their mother. The Westerners showed no suchoverlap between self and mom. Depending whether one lives in a culture that views the self asautonomous and unique or as connected to and part of a larger whole, this neural circuit takes onquite different functions. "Cultural neuroscience," as this new field is called, is about discovering such differences. Someof the findings, as with the "me/mom" circuit, buttress longstanding notions of cultural differences. For instance, it is a cultural cliche that Westerners focus on individual objects while East Asians payattention to context and background (another manifestation of the individualism-collectivism split). Sure enough, when shown complex, busy scenes, Asian-Americans and non-Asian-Americansrecruited different brain regions. The Asians showed more activity in areas that processfigure-ground relations--holistic context--while the Americans showed more activity in regions thatrecognize objects. Psychologist Nalini Ambady of Tufts found something similar when she and colleagues showeddrawings of people in a submissive pose (head down, shoulders hunched) or a dominant one (armscrossed, face forward) to Japanese and Americans. The brain′s dopamine-fueled reward circuitbecame most active at the sight of the stance--dominant for Americans, submissive for Japanese--that each volunteer′s culture most values, they reported in 2009. This raises an obviouschicken-and-egg question, but the smart money is on culture shaping the brain, not vice versa. Cultural neuroscience wouldn′t be making waves if it found neurobiological bases only forwell-known cultural differences. It is also uncovering the unexpected. For instance, a 2006 studyfound that native Chinese speakers use a different region of the brain to do simple arithmetic (3 + 4)or decide which number is larger than native English speakers do, even though both use Arabicnumerals. The Chinese use the circuits that process visual and spatial information and planmovements (the latter may be related to the use of the abacus). But English speakers use languagecircuits. It is as if the West conceives numbers as just words, but the East imbues them withsymbolic, spatial freight. (Insert cliche about Asian math geniuses.) "One would think that neuralprocesses involving basic mathematical computations are universal," says Ambady, but they "seemto be culture-specific." Not to be the skunk at this party, but I think it′ s important to ask whether neuroscience revealsanything more than we already know from, say, anthropology. For instance, it′s well known thatEast Asian cultures prize the collective over the individual, and that Americans do the opposite. Does identifying brain correlates of those values offer any extra insight After all, it′s not as ifanyone thought those values are the result of something in the liver. Ambady thinks cultural neuro-science does advance understanding. Take the me/mom finding,which, she argues, "attests to the strength of the overlap between self and people close to you incollectivistic cultures and the separation in individualistic cultures. It is important to push theanalysis to the level of the brain." Especially when it shows how fundamental cultural differencesare--so fundamental, perhaps, that "universal" notions such as human rights, democracy, and thelike may be no such thing. Which of the following may best describe the author′s attitude towards universal culturalconcepts in the last paragraph
A.Doubtful.
B.Positive.
C.Negative.
D.Neutral.

[单选题]请阅读Passage 2。完成第小题。 Passage 2 We had been wanting to expand our children's horizons by taking them to a place that was unlike anything we'd been exposed to during our travels in Europe and the United States. In thinking about what was possible from Geneva, where we are based, we decided on a trip to Istanbul. We envisioned the trip as a prelude to more exotic ones, perhaps to New Delhi or Bangkok later this year, but thought our ll-and 13-year-olds needed a first step away from manicured boulevards and pristine monuments. What we didn't foresee was the reaction of friends, who warned that we were putting our children "in danger", referring vaguely, and most incorrectly, to disease, terrorism or just the unknown. To help us get acquainted with the peculiarities of Istanbul and to give our children a chance to choose what they were particularly interested in seeing, we bought an excellent guidebook and read it thoroughly before leaving. Friendly warnings didn't change our planning, although we might have more prudently checked with the U.S. State Department's list of trouble spots. We didn't see a lot of children among the foreign visitors during our six-day stay in Istanbul, but we found the tourist areas quite safe, very interesting and varied enough even to suit our son, whose oft-repeated request is that we not see "every single" church and museum in a given city. Vaccinations weren't needed for the city, but we were concerned about adapting to the water for a short stay. So we used bottled water for drinking and brushing our teeth, a precaution that may seem excessive, but we all stayed healthy. Taking the advice of a friend, we booked a hotel a 20-minute walk from most of Istanbul's major tourist sites. This not only got us some morning exercise, strolling over the Karakoy Bridge, but took us past a colorful assortment of fishermen,vendors and shoe shiners. From a teenager and pre-teen's view, Istanbul street life is fascinating since almost everything can be bought outdoors. They were at a good age to spend time wandering the labyrinth of the Spice Bazaar, where shops display mounds of pungent herbs in sacks. Doing this with younger children would be harder simply because the streets are so packed with people; it would be easy to get lost. For our two, whose buying experience consisted of department stores and shopping mall boutiques, it was amazing to discover that you could bargain over price and perhaps end up with two of something for the price of one. They also learned to figure out the relative value of the Turkish lira, not a small matter with its many zeros. Being exposed to Islam was an important part of our trip. Visiting the mosques, especially the enormous Blue Mosque, was our first glimpse into how this major religion is practiced. Our children's curiosity already had been piqued by the five daily calls to prayer over loudspeakers in every corner of the city, and the scarves covering the heads of many women. Navigating meals can be troublesome with children, but a kebab, bought on the street or in restaurants, was unfailing!y popular. Since we had decided this trip was not for gourmets, kebabs spared us the agony of trying to find a restaurant each day that would suit the adults' desire to try something new amid children's insistence that the food be served immediately. Gradually, we branched out to try some other Turkish specialties. Although our sons had studied Islam briefly, it is impossible to be prepared for every awkward question that might come up, such as during our visits to the Topkapi Sarayi, the Ottoman Sultans'palace. No guides were available so it was do-it-yourself, using our guidebook, which cheated us of a lot of interesting history and anecdotes that a professional guide could provide. Next time, we resolved to make such arrangements in advance. On this trip, we wandered through the magnificent complex, with its imperial treasures, its courtyards and its harem. The last required a bit of explanation that we would have happily left to a learned third party. Why did the couple choose Istanbul as their first holiday destination? 查看材料
A.They were interested in the churches and museums there.
B.Istanbul's street life is fascinating to their teenage boys.
C.This city could help broaden their vision with new experiences.
D.The city is not listed as a trouble spot by the U.S. State Department.
