单选题Watch a baby between six and nine months old, and you will observe the basic concepts of geometry being learned. Once the baby has mastered the idea that space is three-dimensional, it reached out and begins grasping various kinds of objects. It is then, from perhaps nine to fifteen months, that the concepts of sets and numbers are formed. So far, so good. But now an ominous development takes place. The nerve fibers in the brain insulate themselves in such a way that the baby begins to hear sounds very precisely. Soon it picks up language, and it is then brought into direct communication with adults. From this point on, it is usually downhill all the way for mathematics, because the child now becomes exposed to all the nonsense words and beliefs of the community into which it has been so unfortunate as to have been born. Nature having done very well by the child to this point, having permitted it the luxury of thinking for itself for eighteen months, now abandons it to the arbitrary conventions and beliefs of society. But at least the child knows something of geometry and numbers, and it will always retain some memory of the early happy days, no matter what vicissitudes it may suffer later on. The main reservoir of mathematical talent in any society is thus possessed by children who are about two years old, children who have just learned to speak fluently.

单选题There is a battle going in Australia between Aborigines and archaeologists. The Aborigines say that ancient bones and other artifacts should be reburied. The archaeologists say that to do so would mean the end of archaeology. Rocky Satiny, president of the Tasmanian Aboriginal Land Council, wants all archaeological excavation in Tasmania stopped. Sainty told The Bulletin: "Aboriginal people know how long we"ve lived here. We know how we trade. The sites that have been excavated are very significant to us. We couldn"t expect someone to go and dig up graves of the Whites at the back of Hobart, well, we have the same feelings." Last year, Sainty and the council took two La Trobe University archaeologists to court in an effort to have excavated material returned. University of Western Australia archaeologists had already returned some excavated material. The artifacts, 17,000 years old, had been dug up in the King River Valley. After the material was returned to them, the Aborigines scattered it over the lake "to heal the site". The La Trobe archaeologists, Jim Allen and Tim Murray, were shocked. They refused to hand over the artifacts they had collected until they had finished their analysis. The courts, however, ordered Allen and Murray to return the material to Tasmania. A track was needed to transport the 500,000 items. Allen is angry. "This decision means I will never again excavate on a site in Australia, because it would carry at least the potential problem we"ve encountered there. It would be unethical to take any material out of the ground knowing that it could be vandalized in this way somewhere down the track." His colleague, Tim Murray, believes the irony of the current situation is that the work of archaeologists has given Aborigines a new sense of pride. "Archaeologists provide a service both to Aboriginal people and the general Australian public," Murray says. "We found the way of making meaningful a whole history of this country before the arrival of Europeans. If that becomes more and more difficult, then the kind of silence that existed before the development of Aboriginal history will return."

单选题{{B}}Part A{{/B}}{{B}}Directions:{{/B}} Read the following four texts. Answer the questions below each text by choosing A, B, C or D. Mark your answers on ANSWER SHEET 1.{{B}}Text 1{{/B}} This past academic year, 146 New York City kids from 4 to 14 dutifully attended Rosalyn Chao's Mandarin class at St. Patrick's Old Cathedral Academy. Many of the students were first-generation Americans; for several, Mandarin would be their third language, after English and Spanish. Get used to this picture; around the world, more adults and kids are learning Chinese. Beijing is pouring money into new Confucius Institutes (Chinese language and culture centers), and two U.S. senators recently proposed spending $1.3 billion on Chinese-language programs over the next five years. From Ulan Bator to Chicago, it sometimes seems as if everyone is trying to learn the language now spoken by a fifth of the world's population. Their reasoning is easy to understand. China is booming, and citizens around the globe want a piece of the action. Speaking Mandarin can facilitate communication with newly wealthy Chinese tourists or smooth bilateral trade relations. In a form of intense cultural diplomacy, Beijing is also promoting its films, music, art and language as never before. Front and center are the Confucius Institutes, modeled on the British Council, Germany's Goethe Institutes or the Alliance Francaise. China's Ministry of Education is sending thousands of language instructors to foreign programs and inviting foreign students from Asia, Africa and elsewhere to study in its universities. As a result, Beijing predicts that 100 million individuals will be studying Mandarin as a second language by the end of the decade. The U.S. Department of Education announced earlier this year that it hopes to have 5 percent of all elementary, secondary and college students enrolled in Mandarin studies by 2010. The Chinese boom hasn't escaped criticism, however. For one thing, the language is hard, with more than 2,500 characters generally employed in daily writing and a complex tonal speaking system. Then there's the danger that other important languages, such as Russian or Japanese, will be neglected; for example, there are now 10 times more students learning Mandarin than Japanese in the United States. And other countries fear a growing encroachment(侵蚀) of Chinese power; some Africans have complained about Beijing's "neocolonialist(新殖民主义)" attitudes, for example, and this could breed resentment against Confucius Institutes on their soil. Yet most Mandarin students, like those at St. Pat's, aren't letting such concerns dissuade them. Mandarin represents a new way of thinking. Chao says that" we must begin preparing our students for the interconnected world." Accordingly, she has encouraged her Mandarin students to correspond with pen pals in Shanghai. Chao says that" in reading the Chinese students' letters, we learned quickly that American students are far behind their Asian counterparts." If they hope to catch up to their Chinese competitors, her students--like the growing legions of Mandarin pupils around the globe -- are going to have to study hard indeed.

单选题Sustainable management is seen as a practical and economical way of protecting species from extinction. Instead of depending on largely ineffective laws against poaching(偷猎), it gives local people a good economic reason to preserve plants and animals. In Zimbabwe, for instance, there is a sustainable management project to protect elephants. Foreign tourists pay large sums of money to kill these animals for sports. This money is then given to the inhabitants of the area where the hunting takes place. In theory, locals will be encouraged to protect elephants, instead of poaching them because of the economic benefit involved. This sounds like a sensible strategy, but it remains to be seen whether it will work. With corruption in these developing countries, some observers are skeptical(怀疑的) that the money will actually reach the people it is intended for. Others wonder how effective the locals will be at stopping poachers. There are also questions about whether sustainable management is practical when it comes to protecting forests. In theory, the principle should be the same as with elephants—allow logging companies to cut down certain number of trees, but not so many as to completely destroy the forest. Sustainable management of forests requires controls on the number of trees which are cut down, as well as investment in replacing them. Because almost all tropical forests are located in countries which desperately need revenue from logging, there are few regulations and incentive to do this. One solution might be to certify wood which comes from sustainably managed forests. In theory, consumers would buy only this wood and so force logging companies to go "green" or go out of business. Unfortunately, unrestricted logging is so much more profitable that wood prices from managed forests would cost up to five times more—an increase that consumers, no matter how "green", are unlikely to pay.
