单选题Culture is transmitted largely by language and by the necessity for people in close contact to co-operate. The more extensive the communications network, the greater the exchange of ideas and beliefs and the more alike people become--in toleration of diversity if nothing else. Members of a culture or a nation are generally in closer contact with one another than with members of other cultures or nations. They become more like each other and more unlike others. In this way, there develops "national character", which is the statistical tendency for a group of people to share values and follow similar behavior patterns. Frequently, the members of one culture will interpret the "national characteristics" of another group in terms of their own values. For example, the inhabitants of a South Pacific island may be considered "lazy" by citizens of some industrialized nations. On the other hand, it may be that the islanders place a great value on social relationships but little value on "productivity", and crops grow with little attention. The negative connotation of the label "lazy" is thus unjustified from the point of view of the island culture. Stereotypes, such as "lazy", "inscrutable", and "dishonest" give people the security of labels with which to react to others in a superficial way, but they are damaging to real understanding among members of different cultures. People react more to labels than to reality. A black American Peace Corps volunteer, for instance, is considered and called a white man by black Africans. The "we--they" distinction applies to whatever characteristic the "wes" have and the "theys" do not have-- and the characteristics attributed to the "theys" are usually ones with a negative value. The distinction becomes most obvious in times of conflict. For this reason, it is often suggested the only thing that might join all men together on this planet would be an invasion from outer space. "We", the earthlings, would then fight "them", the outsiders. Given the great diversities- real and imagined- among people of the world, is there any foundation for hope that someday all men might join together to form a single and legitimate world government? The outcome will probably depend on the political evolution of mankind.

单选题In Second Nature, Nobel Prize-winning neuroscientist Gerald Edelman argues that the brain and mind are unified, but he has little patience with the claim that the brain is a computer. Fortunately for the general reader, his explanations of brain function are accessible, reinforced by concrete examples and metaphors. Edelman suggests that thanks to the recent development of instruments capable of measuring brain structure within millimeters and brain activity within milliseconds, perceptions, thoughts, memories, willed acts, and other mind matters traditionally considered private and impenetrable to scientific scrutiny now can be correlated with brain activity. The author describes three unifying insights that correlate mind matters with brain activity. First, even distant neurons will establish meaningful connections (circuits) if their patterns are synchronized. Second, experience can either strengthen or weaken synapses (neuronal connections). Finally, there is reentry, the continued signaling from one brain region to another and back again along massively parallel nerve fibers. Edelman concedes that neurological explanations for consciousness and other aspects of mind are not currently available, but he is confident that they will be soon. Meanwhile, he is comfortably hazarding a guess: "All of our mental life.., is based on the structure and dynamics of our brain," Despite this optimism about the explanatory powers of neuroscience, Edelman acknowledges the pitfalls in attempting to explain all aspects of the mind in neurological terms. Indeed, culture--not biology--is the primary determinant of the brain's evolution, and has been since the emergence of language, he notes. However, I was surprised to learn that he considers Sigmund Freud "the key expositor of the effects of unconscious processes on behavior". Such a comment ignores how slightly Freud's conception of the unconscious, with its emphasis on sexuality and aggression, resembles the cognitive unconscious studied by neuroscientists. Still, Second Nature is well worth reading. It serves as a bridge between the traditionally separate camps of "hard" science and the humanities. Readers without at least some familiarity with brain science will likely find the going difficult at certain points. Nonetheless, Edelman has achieved his goal of producing a provocative exploration of"how we come to know the world and ourselves".

单选题{{B}}Text 1{{/B}} British cancer researchers have found that childhood leukaemia is caused by an infection, and clusters of cases around industrial sites are the result of population mixing that increases exposure. The research published in the British Journal of Cancer backs up a 1988 theory that some as-yet unidentified infection caused leukaemia—not the environmental factors widely blamed for the disease. "Childhood leukaemia appears to be an unusual result of a common infection," said Sir Richard Doll, an internationally-known cancer expert who first linked tobacco with lung cancer in 1950. "A, virus is the most likely explanation. You would get an increased risk of it if you suddenly put a lot of people from large towns in a rural area, where you might have people who had not been exposed to the infection. "Doll was commenting on the new findings by researchers at Newcastle University, which focused on a cluster of leukaemia cases around the Sellafield nuclear reprocessing plant in Cumbria in northern England. Scientists have been trying to establish why there was more leukaemia in children around the Sellafield area, but have failed to establish a link with radiation or pollution. The Newcastle University research by Heather Dickinson and Louise Parker showed the cluster of cases could have been predicted because of the mount of population mixing going on in the area, as large numbers of construction workers and nuclear staff moved into a rural setting. "Our study shows that population mixing can account for the (Sellafield) leukaemia cluster and that all children, whether their parents are newcomers or locals, are at a higher risk if they are born in an area of high population mixing, "Dickinson said in a statement issued by the Cancer Research Campaign, which publishes the British Journal of Cancer. Their paper adds crucial weight to the 1988 theory put forward by Leo Kinlen, a cancer epidemiologist at Oxford University, who said that exposure to a common unidentified infection through population mixing resulted in the disease.

单选题The Aleuts, residing on several islands of the Aleutian Chain, the Pribilof islands, and the Alaskan Peninsula, have possessed a written language since 1825, when the Russian missionary Ivan Veniaminov selected appropriate characters of the Cyrillic alphabet to represent Aleut speech sounds, recorded the main body of Aleut vocabulary, and formulated grammatical rules. The Czarist Russian conquest of the proud, independent sea hunters was so devastatingly thorough that tribal traditions, even tribal memories, were almost obliterated. The slaughter of the majority of an adult generation was sufficient to destroy the continuity of tribal knowledge, which was dependent upon oral transmission. As a consequence, the Aleuts developed a fanatical devotion to their language as their only cultural heritage. The Russian occupation placed a heavy linguistic burden on the Aleuts. Not only were they compelled to learn Russian to converse with their overseers and governors, but they had to learn Old Slavonic to take an active part in church services as well as to master the skill of reading and writing their own tongue. In 1867, when the United States purchased Alaska, the Aleuts were unable to break sharply with their immediate past and substitute English for any one of their three languages. To communicants of the Russian Orthodox Church a knowledge of Slavonic remained vital, as did Russian, the language in which one conversed with the clergy. The Aleuts came to regard English education as a device to wean them from their religious faith. The introduction of compulsory English schooling caused a minor renascence of Russian culture as the Aleut parents sought to counteract the influence of the schoolroom. The harsh life of the Russian colonial rule began to appear more happy and beautiful in retrospect. Regulations forbidding instruction in any language other than English increased its unpopularity, The superficial alphabetical resemblance of Russian and Aleut linked the two tongues so closely that every restriction against teaching Russian was interpreted as an attempt to eradicate the Aleut tongue. From the wording of many regulations, it appears that American administrators often had not the slightest idea that the Aleuts were clandestinely reading and writhing their own tongue or even had a written language of their own. To too many officials, anything in Cyrillic letters was Russian and something to be stamped out. Bitterness bred by abuses and the exploitations the Aleuts suffered from predatory American traders and adventurers kept alive the Aleut resentment against the language spoken by Americans. Gradually, despite the failure to emancipate the Aleuts from a sterile past by relating the Aleut and English languages more closely, the passage of years has assuaged the bitter misunderstandings and caused an orientation away from Russian toward English as their second language, but Aleut continues to be the language that molds their thought and expression.

单选题There are those whom we instantly recognize as clinging to the traditional values of travel, the people who endure a kind of alienation and panic in foreign parts for the after-taste of having sampled new scenes. On the whole, travel at its best is rather comfortless, but travel is never easy: you get very tired, you get lost, you get your feet wet, you get little co-operation, and—if it is to have any value at all—you go alone. Homesickness is part of this kind of travel. In these circumstances, it is possible to make interesting discoveries about oneself and one"s surroundings. Travel has less to do with distance than with insight: it is, very often, a way of seeing. The second group of travelers has only appeared in numbers in the best twenty years. For these people, paradoxically, travel is an experience of familiar things; it is travel that carries with it the illusion of immobility. It is going to a familiar airport and being strapped into a seat and held captive for a number of hours—immobile; then arriving at an almost identical airport; being whisked to a hotel so fast it is not like movement at all, and the hotel and the food are identical to the hotel and the food in the city one has just left. This is all tremendously reassuring and effortless; indeed, it is possible to go from, say, London to Singapore and not experience the feeling of having traveled anywhere. For many years in the past, this was enjoyed by the rich. It is wrong to call it tourism, because businessmen also travel this way; and many people, who believe themselves to be travelers, object to being called tourists. The luxury travelers of the past set an example for the package tourists of today. In this sort of travel you take your society with you: your language, your food, your styles of hotel and service. It is of course the prerogative of rich nations—America, Western Europe, and Japan. It has had a profound effect on our view of the world. It has made real travel greatly sought-after and somewhat rare. And I think it has caused a resurgence of travel writing. As everyone knows, travel is very unsettling, and it can be quite hazardous and worrying. One way of overcoming this anxiety is to travel packaged in style: luxury is a great remedy for the alienation of travel. What helps calm us is a reminder of stability and protection, and what the average package tourist looks for in foreign surroundings is familiar sights.
