单选题 That experiences influence subsequent behaviour is evidence of an obvious but nevertheless remarkable activity called remembering. Learning could not occur without the function popularly named memory. Constant practice has such an effect on memory as to lead to skilful performance on the piano, to recitation of a poem, and even to reading and understanding these words. So-called intelligent behaviour demands memory, remembering being a primary requirement for reasoning. The ability to solve any problem or even to recognize that a problem exists depends on memory. Typically, the decision to cross a street is based on remembering many earlier experiences. Practice (or review)tends to build and maintain memory for a task or for any learned material. Over a period of no practice, what has been learned tends to be forgotten; and the adaptive consequences may not seem obvious. Yet, dramatic instances of sudden forgetting can seem to be adaptive. In this sense, the ability to forget can be interpreted to have survived through a process of natural selection in animals. Indeed, when one's memory of an emotionally painful experience lead to serious anxiety, forgetting may produce relief. Nevertheless, an evolutionary interpretation might make it difficult to understand how the commonly gradual process of forgetting survived natural selection. In thinking about the evolution of memory together with all its possible aspects, it is helpful to consider what would happen if memories failed to fade. Forgetting clearly aids orientation in time, since old memories weaken and the .new tend to stand out, providing clues for inferring duration. Without forgetting, adaptive ability would suffer, for example, learned behaviour that might have been corrected a decade ago may no longer be. Cases are recorded of people who (by ordinary standards)forgot so little that their everyday activities were full of confusion. This forgetting seems to serve that survival of the individual and the species. Another line of thought assumes a memory storage system of limited capacity that provides adaptive flexibility specifically through forgetting. In this view, continual adjustments are made between learning or memory storage (input) and forgetting (output). Indeed, there is an evidence that the rate at which individuals forget is directly related to how much they have learned. Such data offers gross support of contemporary models of memory that assume an input-output balance.

单选题Britain no longer dominates Anglophone education. Students want more, and the old empire is happy to give it to them. A good name and a British campus are no longer enough to pull in high-paying overseas recruits. The competition within the world of English-language higher education is growing increasingly intense. Today's international students don’t automatically head to the United States or the United Kingdom; they consider a slew of factors before making their pick. Already, Britain is starting to suffer as it finds itself in a fierce three-way contest for market share. On the one hand, U.S. colleges are recovering fast in overseas recruitment. On the other, a batch of commonwealth countries is coming on strong and eating into Britain's market share. Consider Singapore, which four years ago set out to lure branches of foreign colleges. The number of overseas students there has since climbed 46 percent. And in the first three years of the decade, the number of foreign students in New Zealand almost quadrupled. Then there’s Australia. Foreigners now make up about a quarter of its entire student body. Australia shows that the secret to success often has as much to do with government policy as with academic philosophy. Lavish grants can offset the Brits’ and the Americans’ edge in prestige. Foreign students at state-run schools in Singapore now get an 80 percent discount. An engineering degree that costs about $30,000 a year at Harvard runs just $2,000 at the University of Malaya, thanks to heavy subsidies. The biggest factor today seems to be the prospect of employment. A degree from an Australian university now puts graduates on the fast track to permanent residency. And London offers an automatic 12-month work permit to most overseas recruits. But Britain can’t do anything about its location. Why go all the way to the United Kingdom -- or to the United States -- when there’s now a good English- language college just a few hours’ flight from Shanghai or Mumbai? But few countries can match Australia's main selling point. Its sunny outdoors image works strongly to its advantage among international students. Yet no country can afford to throw in the towel. Cuts in government spending have forced colleges to look elsewhere for money. Overseas recruits have thus become an increasingly critical source of cash: in Britain the average university now looks to foreign students to provide at least 10 percent of its income. Other trends could soon make things even more desperate. Today China is one of the biggest sources of traveling students. But for how much longer? The country is now busy developing its own elite institution and ordinary colleges. If this trend continues, the developed world is going to lose its largest client. The scramble for business in the Anglo world is already ferocious(激烈的), while the market is expanding. Just wait till it starts to contract.
