单选题Modern technology and science have produced a wealth of new materials and new ways of using old materials. For the artist this means wider opportunities. There is no doubt that the limitations of materials and nature of tools both restrict and shape a man's work. Observe how the development of plastics and light metals along with new methods of welding has changed the direction of sculpture. Transparent plastic materials allow one to look through an object, to see its various sides superimposed on each other (as in Cubism or in an X-ray). Today, welding is as prevalent as casting was in the past. This new method encourages open designs, where surrounding and intervening space becomes as important as form itself. More ambiguous than other scientific inventions familiar to modern artists, but no less influential, are the psychoanalytic studies of Freud and his followers, discoveries that have infiltrated recent art, especially Surrealism. The Surrealists, in their struggle to escape the monotony and frustrations of everyday life, claimed that dreams were the only hope. Turning to the irrational world of their unconscious, they banished all dine barriers and moral judgments to combine disconnected dream experiences from the past, present and intervening psychological states. The Surrealists were concerned with overlapping emotions more than with overlapping forms. Their paintings often become segmented capsules of associative experiences. For them, obsessive and often unrelated images replaced the direct emotional message of expressionism. They did not need to smash paint and canvas; they went beyond this to smash the whole continuity of logical thought. There is little doubt that contemporary art has taken much from contemporary life. In a period when science has made revolutionary strides, artists in their studios have not been unaware of scientists in their laboratories. But this has rarely been a one-way street. Painters and sculptors though admittedly influenced by modern science, have also molded and changed our world. If breakup has been a vital part of their expression, it has not always been a symbol of destruction. Quite the contrary, it has been used to examine more fully, to penetrate more deeply, to analyze more thoroughly, to enlarge, isolate and make more familiar certain aspects of life that earlier we were apt to neglect. In addition, it sometimes provides rich multiple experiences so organized as not merely to reflect our world, but in fact to interpret it.

单选题In such a changing, complex society formerly simple solutions to informational needs become complicated. Many of life"s problems which were solved by asking family members, friends or colleagues are beyond the capability of the extended family to resolve. Where to turn for expert information and how to determine which expert advice to accept are questions facing many people today. In addition to this, there is the growing mobility of people since World War Ⅱ. As families move away from their stable community, their friends of many years, their extended family relationships, the informal flow of information is cut off, and with it the confidence that information will be available when needed and will be trustworthy and reliable. The almost unconscious flow of information about the simplest aspects of living can be cut off. Thus, things once learned subconsciously through the casual communications of the extended family must be consciously learned. Adding to societal changes today is an enormous stockpile of information. The individual now has more information available than any generation, and the task of finding that one piece of information relevant to his or her specific problem is complicated, time-consuming and sometimes even overwhelming. Coupled with the growing quantity of information is the development of technologies which enable the storage and delivery of more information with greater speed to more locations than has ever been possible before. Computer technology makes it possible to store vast amounts of data in machine-readable files, and to program computers to locate specific information. Telecommunication developments enable the sending of messages via television, radio, and very shortly, electronic mail to bombard people with multitudes of messages. Satellites have extended the power of communications to report events at the instant of occurrence. Expertise can be shared world wide through teleconferencing, and problems in dispute can be settled without the participants leaving their homes and/or jobs to travel to a distant conference site. Technology has facilitated the sharing of information and the storage and delivery of information, thus making more information available to more people. In this world of change and complexity, the need for information is of greatest importance. Those people who have accurate, reliable up-to-date information to solve the day-to-day problems, the critical problems of their business, social and family life, will survive and succeed. "Knowledge is power" may well be the truest saying and access to information may be the most critical requirement of all people.

单选题 According to a survey, which was based on the responses of over 188, 000 students, today's traditional- age college freshmen are "more materialistic and less altruistic (利他主义的) "than at any time in the 17 years of the poll. Not surprising in these hard times, the student's major objective "is to be financially well off. Less important than ever is developing a meaningful philosophy of life. It follows then that today the most popular course is not literature or history but accounting". Interest in teaching, social service and the "altruistic" fields is at a low. on the other hand, enrollment in business programs, engineering and computer science is way up. That's no surprise either. A friend of mine (a sales representative for a chemical company) was making twice the salary of her college instructors her first year on the job--even before she completed her two-year associate degree. While it's true that we all need a career, it is equally tame that our civilization has accumulated an incredible amount of knowledge in fields far removed flora our own and that we are better for ear understanding of these other contributions--be they scientific or artistic. It is equally true that, in studying the diverse wisdom of others, we learn how to think. More important, perhaps, education teaches us to see the connections between things, as well as to see beyond our immediate needs. Weekly we mad of unions who went on strike for higher wages, only to drive their employer out of business. No company; no job. How shortsighted in the long run ! But the most important argument for a broad education is that in studying the accumulated wisdom of the ages, we improve our moral sense. I saw a cartoon recently which shows a group of businessmen looking puzzled as they sit around a conference table; one of them is talking on the intercom (对讲机): "Miss Baxter," he says, "could you please send in someone who can distinguish fight from wrong?" From the long-term point of view, that's what education really ought to be about.

单选题{{B}}Passage Four{{/B}} Many people seem to think that science fiction is typified by the covers of some of the old pulp magazines: the Bug-Eyed Monster, embodying every trait and feature that most people find repulsive, is about to grab, and presumably ravish, a sweet, blonde, curvaceous, scantily-clad Earth girl. This is unfortunate because it demeans and degrades a worthwhile and even important literary endeavor. In contrast to this unwarranted stereotype, science fiction rarely emphasizes sex, and when it does, it is more discreet than other contemporary fiction. Instead, the basic interest of science fiction lies in the relation between man and his technology and between man and the universe. Science fiction is a literature of change and a literature of the future, and while it would be foolish to claim that science fiction is a major literary genre at this time, the aspects of human life that it considers make it well worth reading and studying ——for no other literary form does quite the same things. The question is: what is science fiction? And the answer must be, unfortunately, that there have been few attempts to consider this question at any length or with much seriousness; it may well be that science fiction will resist any comprehensive definition of its characteristics. To say this, however, does not mean that there are no ways of defining it nor that various facets of its totality cannot be clarified. To Begin, the following definition should be helpful: science fiction is a literary sub-genre which postulates a change (for human beings) from conditions as we know them and follows the implications of these changes to a conclusion. Although this definition will necessarily be modified and expanded, and probably changed, in the course of this exploration, it covers much of the basic groundwork and provides a point of departure. The first point ——that science fiction is a literary sub-genre ——is a very important one, but one which is often overlooked or ignored in most discussions of science fiction. Specifically, science fiction is either a short story or a novel. There are only a few dramas which could be called science fiction, with Karel Capek's RUR (Rossum's Universal Robots) being the only one that is well known; the body of poetry that might be labeled science fiction is only slightly larger. To say that science fiction is a sub-genre of prose fiction is to say that it has all the basic characteristics and serves the same basic functions in much the same way as prose fiction in general ——that is, it shares a great deal with all other novels and short stories. Everything that can be said about prose fiction, in general applies to science fiction. Every piece of science fiction, whether short story or novel, must have a narrator, a story, a plot, a setting, character, language, and theme. And like any prose, the themes of science fiction are concerned with interpreting man's nature and experience in relation to the world around him. Themes in science fiction are constructed and presented in exactly the same ways that themes are dealt with in any other kind of fiction. They are the result of a particular combination of narrator, story, plot, character, setting, and language. In short, the reasons for reading and enjoying science fiction, and the ways of studying and analyzing it, are basically the same as they would be for any other story or novel.

单选题The contribution of genes make intelligence increase as children grow older. This goes against the notion that most people hold that as we age, environmental influences gradually overpower the genetic legacy we are born with and may have implications for education. "People assume the genetic influence goes down with age because the environmental differences between people pile up in life," says Robert Plomin. "What we found was quite amazing, and goes in the other direction. " Previous studies have shown variations in intelligence are at least partly due to genetics. To find out whether this genetic contribution varies with age, Plomin's team pooled data from six separate studies carried out in the US, the UK, Australia and the Netherlands, involving a total of 11,000 pairs of twins. In these studies, the researchers tested twins on reasoning, logic and arithmetics to measure a quantity called general cognitive ability, or "G" . Each study also included both identical twins, with the same genes, and fraternal twins, sharing about half their genes, making it possible to distinguish the contributions of genes and environment to their G scores. Plomin's team calculated that in childhood, genes account for about 41 percent of the variation in intelligence. In adolescence, this rose to 55 percent; by young adolescence, it was 66 percent. No one knows why the influence from genes should increase with age, but Plomin suggests that as children get older, they become better at exploiting and manipulating their environment to suit their genetic needs, and says "Kids with high G will use their environment to foster their cognitive ability and choose friends who are like-minded. " Children with medium to low G may choose less challenging pastimes and activities, further emphasizing their genetic legacy. Is there any way to interfere with the pattern? Perhaps. "The evidence of strong heritability doesn't mean at all that there is nothing you can do about it, " says Susanne Jaeggi, "From our own work, the ones that started off with lower IQ scores had higher gains after training. " Plomin suggests that genetic differences may be more emphasized if all children share an identical curriculum instead of it being tailored to children's natural abilities. "My inclination would be to give everyone a good education, but put more effort into the lower end," he says. Intelligence researchers Paul Thompson agrees: "It shows that educators need to steer kids towards things drawing out their natural talents. /
