单选题 Watch out! Here comes London Mayor Boris Johnson riding a bicycle from his new bike hire plan. "What We've put in a new form of public transport. These bikes are going to belong to everybody. " "More than 12000 people have signed up for the plan. They each receive a key at a cost of three pounds, with costs at one pound for a 24-hour membership, five pounds for seven days, and 45 pounds for an annual membership. " John Payne, a London teacher who cycles a lot, is among the first to use the system. "It's very comfortable. For people who don't cycle much I think it'll he very useful. But for people who cycle regularly, they are possibly a bit slow, But they' re perfect for London streets, very strong. I think they'll he very widely used. " And Johnson says it's of good value. "I think it's extremely good value. The first half hour is free. If you cycle smart and you cycle around London on—most journeys in London take less than half an hour, you can cycle the whole day free. "Some 5000 bikes are currently available at over 300 docking stations(租车点) in central London. Johnson says the city will gradually expand the system. "Clearly one of our ambitions is to make sure that in 2012 when the world comes to London, they will be able to use London hire bikes to go to the Olympic Stadiums. "

单选题There's a simple premise behind what Larry Myers does for a living: If you can smell it, you can find it. Myers is the founder of Auburn University's Institute for Biological Detection Systems, the main task of which is to chase the ultimate in detection devices—an artificial nose. For now, the subject of their research is little more than a stack of gleaming chips tucked away in a laboratory drawer. But soon, such a tool could be hanging from the belts of police, arson (纵火) investigators and food-safety inspectors. The technology that they are working on would suggest quite reasonable that, within three to five years, we'll have some workable sensors ready to use. Such devices might find wide use in places that attract terrorists. Police could detect drugs, bodies and bombs hidden in cars, while food inspectors could easily test food and water for contamination. The implications for revolutionary advances in public safety and the food industry are astonishing. But so, too, are the possibilities for abuse: Such machines could determine whether a woman is ovulating (排卵), without a physical exam—or even her knowledge. One of the traditional protectors of American liberty is that it has been impossible to search everyone. That's getting not to be the case. Artificial biosensors created at Auburn work totally differently from anything ever seen before. AromaScan, for example, is a desktop machine based on a bank of chips sensitive to specific chemicals that evaporate into the air. As air is sucked into the machine, chemicals pass over the sensor surfaces and produce changes in the electrical current flowing through them. Those current changes are logged into a computer that sorts out odors based on their electrical signatures. Myers says they expect to load a single fingernail-size chip with thousands of odor receptors (感受器), enough to create a sensor that's nearly as sensitive as a dog's nose.

单选题{{B}}Passage Three{{/B}} It is hard to predict how science is going to turn out, and if it is really good science it is impossible to predict. If the things to be found are actually new, they are by definition unknown in advance. You cannot make choices in this matter. You either have science or you don't, and if you have it you are obliged to accept the surprising and disturbing pieces of information, along with the neat and promptly useful bits. The only solid piece of scientific truth about which I feel totally confident is that we are profoundly ignorant about nature. I regard this as the major discovery of the past hundred years of biology. It is, in its way, an illuminating piece of news. It would have amazed the brightest minds of the 18th century Enlightenment to be told by any of us how little we know and how bewildering seems the way ahead. It is this sudden confrontation with the depth and scope of ignorance that represents the most significant contribution of the 20th century science to the human intellect. In earlier times, we either pretended to understand how things worked or ignored the problem, or simply made up stories to fill the gaps. Now that we have begun exploring in earnest, we are getting glimpses of how huge the questions are, and how far they are from being answered. Because of this, we are depressed. It is not so bad being ignorant if you are totally ignorant; the hard thing is knowing in some detail the reality of ignorance, the worst spots and here and there the not-so-bad spots, but no true light at the end of the tunnel nor even any tunnels that can yet be trusted. But we are making a beginning, and there ought to be some satisfaction. There are probably no questions we can think up that can't be answered, sooner or later, including even the matter of consciousness; to be sure, there may well be questions we can't think up, ever, and therefore limits to the reach of human intellect, but that is another matter. Within our limits, we should be able to work our way through to all our answers, if we keep at it long enough, and pay attention.

单选题I probably know him ______ but not ______.

单选题{{B}}练习二{{/B}} Extraordinary creative activity has been characterized as revolutionary, flying in the face of what is established and producing not what is acceptable but what will become accepted. According to this formulation, highly creative activity transcends the limits of an existing form and establishes a new principle of organization. However, the idea that extraordinary creativity transcends established limits is misleading when it is applied to the arts, even though it may be valid for the sciences. Differences between highly creative art and highly creative science arise in part from differences in their goals. For the sciences, a new theory is the goal and end result of the creative act. Innovative science produces new propositions in terms of which diverse phenomena can be related to one another in more coherent ways. Such phenomena as a brilliant diamond or a nesting bird are relegated to the role of data, serving as the means for formulating or testing a new theory. The goal of highly creative art is very different: the phenomenon itself becomes the direct product of the creative act. Shakespeare's Hamlet is not a tract about the behavior of indecisive princes or the uses of political power, nor is Picasso's painting Guernica primarily a propositional statement about the Spanish Civil War or the evils of fascism. What highly creative artistic activity produces is not a new generalization that transcends established limits, but rather an aesthetic particular. Aesthetic particulars produced by the highly creative artist extend or exploit, in an innovative way, the limits of an existing form, rather than transcend that form. This is not to deny that a highly creative artist sometimes establishes a new principle of organization in the history of an artistic field: the composer Monteverdi, who created music of the highest aesthetic value, comes to mind. More generally, however, whether or not a composition establishes a new principle in the history of music has little bearing on its aesthetic worth. Because they embody a new principle of organization, some musical works, such as the operas of the Florentine Camerata, are of signal historical importance, but few listeners or musicologists would include these among the great works of music. On the other hand, Mozart's The Marriage of Figaro is surely among the masterpieces of music even though its modest innovations are confined to extending existing means. It has been said of Beethoven that he toppled the rules and freed music from the stifling confines of convention. But a close study of his compositions reveals that Beethoven overturned no fundamental rules. Rather, he was an incomparable strategist who exploited limits—the rules, forms, and conventions that he inherited from predecessors such as Haydn and Mozart, Handel and Bach--in strikingly original ways.

单选题Directions: In this part there are four passages, each with four suggested answers. Choose the one that you think is the best answer. Mark your Answer Sheet by drawing with a pencil a short bar across the corresponding letter in the brackets. The human brain contains 10 thousand million cells and each of these may have a thousand connections. Such enormous numbers used to discourage us and cause us to dismiss the possibility of making a machine with humanlike ability, but now we have grown used to moving forward at such a pace we can be less sure. Quite soon, in only 10 or 20 years perhaps, we will he able to assemble a machine as complex as the human brain, and if we can we will. It may then take us a long time to render it intelligent by loading in the right software (软件) or by altering the architecture but that too will happen. I think it certain that in decades, not centuries, machines of silicon (硅) will arise first to rival and then exceed their human ancestors. Once they exceed us they will be capable of their own design. In a real sense they will he able to reproduce themselves. Silicon will have ended carbon's long control. And we will no longer be able to claim ourselves to be the finest intelligence in the known universe. As the intelligence of robots increases to match that of humans and as their cost declines through economies of scale we may use them to expand our frontiers, first on earth through their ability to withstand environments, harmful to ourselves. Thus, deserts may bloom and the ocean beds be mined. Further ahead, by a combination of the great wealth this new age will bring and the technology it will provide, the construction of a vast, mancreated world in space, home to thousands or millions of people, will be within our power.

单选题In the past century Irish painting has changed from a British-influenced lyrical tradition to an art that evokes the ruggedness(朴实)and roots of an Irish Celtic past. At the turn of the twentieth century Irish painters, including notables Walter Frederick Osborne and Sir William Orpen, looked elsewhere for influence. Osborne"s exposure to "plain air" painting deeply impacted his stylistic development; and Orpen allied himself with a group of English artists, while at the same time participated in the French avant-garde experiment, both as painter and teacher. However, nationalist energies were beginning to coalesce(接合), reviving interest in Irish culture—including Irish visual arts. Beatrice Elvery"s(1907), a landmark achievement, merged the devotional simplicity of fifteenth-century Italian painting with the iconography(图像学)of Ireland"s Celtic past, linking the history of Irish Catholicism with the still-nascent(初生的)Irish republic. And, although also captivated by the French plain air school, Sir John Lavery invoked the mythology of his native land for a 1928 commission to paint the central figure for the bank note of the new Irish Free State. Lavery chose as this figure, with her arm on a Celtic harp(竖琴), the national symbol of independent Ireland. In Irish painting from about 1910, memories of Edwardian romanticism coexisted with a new sense of realism, exemplified by the paintings of Paul Henry and Se Keating, a student of Orpen"s. Realism also crept into the work of Edwardians Lavery and Orpen, both of whom made paintings depicting World War I, Lavery with a distanced Victorian nobility, Orpen closer to the front, revealing a more sinister and realistic vision. Meanwhile, counterpoint(对照)to the Edwardians and realists came Jack B. Yeats, whose travels throughout the rugged and more authentically Irish West led him to depict subjects ranging from street scenes in Dublin to boxing matches and funerals. Fusing close observations of Irish life and icons with an Irish identity in a new way, Yeats changed the face of Irish painting and became the most important Irish artist of his century.

单选题Britain's government raises millions of pounds each year from the National Lottery (抽奖) and some of this money is used as an additional allowance for the arts. But this money can only be spent on "capital projects", and not on an institution's day-to-day expenses. Lottery money has been made available for many exciting new building projects to improve theatres, galleries and museums. But the project which has received the most publicity is the ￡ 78 million renewal on the Royal Opera House in London's Covent Garden. The House is the home of Britain's greatest opera company, as well as the Royal Ballet(芭蕾舞团). It's also considered to be the best arts institutions -- tickets to the opera can cost up to 200 -- and not everyone is happy that so much lottery money is being used for the benefit of a rich minority. But since builders moved into the Royal Opera House last July, that controversy has been overshadowed by a more serious crisis: the opera company is facing financial collapse. According to a special investigation, the crisis is the result of serious mismanagement by Opera House staff, and there have been calls for its allowance to be withdrawn completely. Now, the Opera House has to wait to hear from a government working party about its future survival.

单选题I have been very luck to have won the Nobel Prize twice. It is, of course, very exciting to have such an important 1 of my work, but the real pleasure was in the work itself. Scientific research is like an exploration of a voyage of discovery. You are 2 trying out new things that have not been done before. Many of them will lead 3 and you have to try something different, but sometimes and experiment does 4 and tells you something new and that it really exciting. 5 small the new finding may be, it is great to think "I am the only person who knows this" and then you will have the fun of thinking what this finding will 6 and of deciding what will be the 7 experiment. One of the best things about scientific research is that you are always doing something different and it is never 8 . These are good times when things go well and the bad times when they 9 . Some people get discouraged at the difficult times, but when I have a failure my policy has always been not to worry but to start planning the next experiment, 10 is always fun.
