单选题The Greek's lofty attitude toward scientific research—and the scientists' contempt of utility —was a long time dying. For a millennium after Archimedes, this separation of mechanics from geometry inhibited fundamental technological progress and in some areas repressed it altogether. But there was a still greater obstacle to change until the very end of the middle ages: the organization of society. The social system of fixed class relationships that prevailed through the Middle Ages(and in some areas much longer)itself hampered improvement. Under this system, the laboring masses, in exchange for the bare necessities of life, did all the productive work, while the privileged few — priests, nobles, and kings — concerned themselves only with ownership and maintenance of their own position. In the interest of their privileges they did achieve considerable progress in defense, in war making, in government, in trade, in the arts of leisure, and in the extraction of labor from their dependents, but they had no familiarity with the process of production. On the other hand, the laborers, who were familiar with manufacturing techniques, had no incentive to improve or increase production to the advantage of their masters. Thus, with one class possessing the requisite knowledge and experience, but lacking incentive and leisure, and the other class lacking the knowledge and experience, there was no means by which technical progress could be achieved. The whole ancient world was built upon this relationship — a relationship as sterile as it was inhuman. The availability of slaves nullified the need for more efficient machinery. In many of the commonplace fields of human endeavor, actual stagnation prevailed for thousands of years. Not all the glory that was Greece and the grandeur that was Rome could develop the windmill or contrive so simple an instrument as the wheelbarrow—products of the tenth and thirteenth centuries respectively. For about twenty-five centuries, two-thirds of the power of the horse was lost because he wasn't shod, and much of the strength of the ox was wasted because his harness wasn't modified to fit his shoulders. For more than rive thousand years, sailors were confined to rivers and coasts by a primitive steering mechanism which required remarkably little alteration(in the thirteenth century)to become a rudder. With any ingenuity at all, the ancient plough could have been put on wheels and the ploughshare shaped to bite and turn the sod instead of merely scratching it — but the ingenuity wasn't forthcoming. And the villager of the Middle Ages, like the men who first had fire, had a smoke hole in the center of the straw and reed thatched roof of his' one-room dwelling(which he shared with his animals), while the medieval charcoal burner(like his Stone Age ancestor)made himself a hut of small branches.

单选题As a wise man once said, we are all ultimately alone. But an increasing number of Europeans are choosing to be so at an ever earlier age. This isn"t the stuff of gloomy philosophical contemplations, but a fact of Europe"s new economic landscape, embraced by sociologists, real-estate developers and ad executives alike. The shift away from family life to solo lifestyle, observes a French sociologist, is part of the "irresistible momentum of individualism" over the last century. The communications revolution, the shift from a business culture of stability to one of mobility and the mass entry of women into the workforce have greatly wreaked havoc on Europeans" private byes. Europe"s new economic climate has largely fosterd the trend toward independence, the current generation of home-aloners came of age during Europe"s shift from social democracy to the sharper, more individualistic climate of American-style capitalism. Raised in an era of privatization and increased consumer choice, today"s tech-savvy workers have embraced a free market in love as well as economics. Modern Europeans are rich enough to afford to live alone, and temperamentally independent enough to want to do so. Once upon a time, people who lived alone tended to be those on either side of marriage-twentysometing professionals or widowed senior citizens, while pensioners, particularly elderly women, make up a large proportion of those living alone, the newest crop of singles are high earners in their 30s and 40s who increasingly view living alone as a lifestyle choice. Living alone was conceived to be negative-dark and cold, while being together suggested warmth and light. But then came along the idea of singles. They were young, beautiful, strong! Now, young people want to live alone. The booming economy means people are working harder than ever. And that doesn"t leave much room for relationships. Pirnpi Arroyo, a 35-year-old composer who lives alone in a house in Paris, says he hasn"t got time to get lonely becanse he has too much work. "I have deadlines which would make life with someone else fairly difficult. Only an Iddeal Woman would make him change his lifestyle," he says. Kaufmann, author of a recent book called "The Single Woman and Prince Charming", thinks this fierce new individualism means that people expext morn and more of mates, so relationships don"t last long--if they start at all. Eppendorf, a blond Berliner with a deep tan, teaches grade school in the mornings. In the afternoon she sunbarthes or sleeps, resting up for going dancing. Just shy of 50, she says she"d never have wanted to do what her mother did--give up a career to raise a family. Instead, "I"ve always done what I wanted to do: live a self-determined life."

单选题{{B}}Passage Five{{/B}} A number of researchers have examined the variables/strategies that affect students' learning English as a second language. This report identifies some of the learner variables/ strategies used by two students in a Hong Kong Technical Institute. The instruments for data collection included observation, interviews and questionnaires. The findings are discussed and some implications highlighted. What makes a 'good' language learner 'good', and what makes a 'poor' language learner 'poor'? What does this imply for the teaching of language in the Hong Kong context? These are the central questions of this assignment. The existing body of research attributes the differences between language learners to learner variables and learner strategies, Learner variables include such things as differences in personality, motivation, style, aptitude and age (Ellis, 1986: chap 5) and strategies refer to "techniques, approaches, or deliberate actions that students take in order to facilitate the learning and recall of both linguistic and content area information" (Chamot, 1987: 71). It is important to note here that what we are considering is not the fact that language learners do and can learn, but why there should be such variations in speed of learning, ability to use the target language, and in achieving examination grades, areas which generally lead to the classification of students as being either 'good' or 'poor'. Learner variables and strategies have been the focus of a number of research projects, (O'Malley et al, 1985, Oxford, 1989). However, to the best of my knowledge, this area has not been researched in Hong Kong classrooms. Since I am a teacher of English working in Hong Kong, gleaning a little of what learner variables and strategies seem to work for local students seems to be a fruitful area of research. In discussing learner variables and strategies, we have to keep in mind the arbitrary nature of actually identifying these aspects. As the existing research points out, it is not possible to observe directly qualities such as aptitude, motivation and anxiety. (Oxford, 1986) We cannot look inside the mind of a language learner and find out what strategies, if any, they are using. These strategies are not visible processes. Also, as Naiman and his colleagues (1978) point out, no single learning strategy, cognitive style or learner characteristic is sufficient to explain success in language learning. The factors must be considered simultaneously to discover how they interact to affect success or failure in a particular language learning situation. Bearing these constraints in mind, the aim of this assignment is to develop two small scale studies of the language learners attempting to gain an overall idea of what strategies are in use and what variables seem to make a difference to Hong Kong students.

单选题"Most episodes of absent-mindedness--forgetting where you lift something or wondering why you just entered a room--are caused by a simple lack of attention," says Schacter, "you are supposed to remember something but you haven't encoded deeply." Encoding, Schacter explains, is a special way of paying attention to an event that has a major impact on recalling it later. Failure to encode properly can create annoying situations. If you put your mobile phone in a pocket, for example, and don't pay attention to what you did because you are involved in a conversation, you'll probably forget that the phone is in the jacket now hanging in your wardrobe. "Your memory itself isn't failing you," says Schacter, "rather you didn't give your memory system the information it needed." Laek of interest can also lead to absent-mindedness. "A man who can recite sports statistics from 30 years ago," says Zelinski, "may not remember to drop a letter in the mailbox.' Women have slightly better memories than men possibly because they pay more attention to their environment and memory relies on just that. "Visual cues can help prevent absent-mindedness." says Schacter. "But be sure the cue is clear and available," he cautions. If you want to remember to take a medication with lunch, put the pill bottle on the kitchen table--don't leave it in the medicine chest and write yourself a note that you keep in a pocket. Another common episode of absent-mindedness like walking into a room and wondering why you're there is most likely because you were thinking about something else. "Everyone does this from time to time,' says Zelinske. The best thing to do is to return to where you were before entering the room and you will likely remember.

单选题 A particular area in which assumptions and values differ between cultures is that of friendship. Friendships among Americans tend to be shorter and less intense than those among people from many other cultures. At least many observers from abroad have this impression. Because Americans are taught to be self-reliant, because they live in a very mobile society, and for many other reasons as well, they tend to avoid deep involvement with other people. Furthermore, Americans tend to" compartmentalize" their friendships, having their" friends at work" ," friends at school", a" tennis friend", and so on. Americans often seem very friendly, even when you first meet them. This friendliness does not usually mean that the American is looking for a deeper relationship. The result of these attitudes and behaviors is sometimes viewed by foreigner as an "inability to be friends". Other times it is seen as a normal way to retain personal happiness in a mobile, ever-changing society. People normally have in their minds stereotypes about people who are different from themselves. Stereotypes are based on limited and incomplete experience and information, but they shape people's thoughts and expectations. Americans have many stereotypes about foreign students in general (for example, that they are very hard working, intelligent, and rich; that they do not speak English well) and about particular categories of foreign students (Chinese are polite Own stereotypes of Americans, for example, that they are arrogant, rude, and generous). There are two stereotypes that often effect male-female relationships involving U. S. and foreign students. The first is the idea, held by some foreign males, that American females are American females, is that male foreign students have no interest in American females other than having sex with them. The existence of these and other stereotypes can give rise to considerable misunderstanding and can block the development of a mutually satisfactory human mind seeks to categorize and classify information, so it is not realistic to suppose people can "forget their stereotypes". But they can be aware of their stereotypes, and be ready to find exceptions to them.
