Mark your answers on ANSWER SHEET 1. (40 points)Text 1Habits are a funny thing. We reach for them mindlessly, setting our brains on auto-pilot and relaxing into the unconscious comfort of familiar routine. ―Not choice, but habit rules the unreflecting herd,‖ William Wordsworth said in the 19th century. In the ever-changing 21st century, even the word ―habit‖ carries a negative implication.So it seems paradoxical to talk about habits in the same context as creativity and innovation. But brain researchers have discovered that when we consciously develop new habits, we create parallel paths, and even entirely new brain cells, that can jump our trains of thought onto new, innovative tracks.Rather than dismissing ourselves as unchangeable creatures of habit, we can instead direct our own change by consciously developing new habits. In fact, the more new things we try – the more we step outside our comfort zone –the more inherently creative we become, both in the workplace and in our own personal lives.But don‘t bother trying to kill off old habits; once those ruts of procedure are worn into the brain, they‘re there to stay. Instead, the ne w habits we deliberately press into ourselves create parallel pathways that can bypass those old roads.―The first thing needed for innovation is a fascination with wonder,‖ says Dawna Markova, author of The Open Mind. ―But we are taught instead to ‗decide,‘ just as our president calls himself ‗the Decider.‘ ‖ She adds, however, that ―to decide is to kill off all possibilities but one. A good innovational thinker is always expl oring the many other possibilities.‖All of us work through problems in ways of which we‘re unaware, she says. Researchers in the late 1960s discovered that humans are born with the capacity to approach challenges in four primary ways: analytically, procedurally, relationally (or collaboratively) and innovatively. At the end of adolescence, however, the brain shuts down half of that capacity, preserving only those modes of thought that have seemed most valuable during the first decade or so of life.The current emphasis on standardized testing highlights analysis and procedure, meaning that few of us inherently use our innovative and collaborative modes of thought. ―This breaks the major rule in the American belief system — that anyone can do anythi ng,‖ explains M. J. Ryan, author of the 2006 book This Year I Will... and Ms. Markova‘s business partner. ―That‘s a lie that we have perpetuated, and it fosters commonness. Knowing what you‘re good at and doing even more of it creates excellence.‖ This is where developing new habits comes in.21. In Wordsworth‘s view, ―habits‖ is characterized by being[A] casual. [B] familiar. [C] mechanical. [D] changeable.22. Brain researchers have discovered that the formation of habits can be[A] predicted. [B] regulated. [C] traced. [D] guided.23. The word ―ruts‖ (Line 1, paragraph 4) is closest in meaning to[A] tracks. [B] series. [C] characteristics. [D] connections.24. Dawna Markova would most probably agree that[A] ideas are born of a relaxing mind.[B] innovativeness could be taught.[C] decisiveness derives from fantastic ideas.[D] curiosity activates creative minds.25. Ryan‘s comments suggest that the practice of standardized testing[A] prevents new habits from being formed.[B] no longer emphasizes commonness.[C] maintains the inherent American thinking model.[D] complies with the American belief system.Text 2It is a wise father that knows his own child, but today a man can boost his paternal (fatherly) wisdom –or at least confirm that he‘s the kid‘s dad.All he needs to do is shell out $30 for paternity testing kit (PTK) at his local drugstore – and another $120 to get the results.More than 60,000 people have purchased the PTKs since they first become available without prescriptions last year, according to Doug Fogg, chief operating officer of Identigene, which makes the over-the-counter kits. More than two dozen companies sell DNA tests directly to the public, ranging in price from a few hundred dollars to more than $2500.Among the most popular: paternity and kinship testing, which adopted children can use to find their biological relatives and families can use to track down kids put up for adoption. DNA testing is also the latest rage among passionate genealogists --- and supports businesses that offer to search for a family‘s geographic roots .Most tests require collecting cells by swabbing saliva in the mouth and sending it to the company for testing. All tests require a potential candidate with whom to compare DNA.But some observers are skeptical, ―There is a kind of false precision being hawked by people claiming they are d oing ancestry testing,‖ says Tr oy Duster, a New York University sociologist. He notes that each individual has many ancestors --- numbering in the hundreds just a few centuries back. Yet most ancestry testing only considers a single lineage, either the Y chromosome inherited through men in a father‘s li ne or mitochondrial DNA, which is passed down only frommothers. This DNA can reveal genetic information about only one or two ancestors, even though, for example, just three generations back people also have six other great-grandparents or, four generations back, 14 other great-great-grandparents.Critics also argue that commercial genetic testing is only as good as the reference collections to which a sample is compared. Databases used by some companies don‘t rely on data collected systematically but rather lump together information from different research projects. This means that a DNA database may differ depending on the company that processes the results. In addition, the computer programs a company uses to estimate relationships may be patented and not subject to peer review or outside evaluation.26. In Paragraphs 1 and 2, the text shows PTK‘s[A] easy availability.[B] flexibility in pricing.[C] successful promotion.[D] popularity with households.27. PTK is used to[A] locate one‘s birth place.[B] promote genetic research.[C] identify parent-child kinship.[D] choose children for adoption.28. Skeptical observers believe that ancestry testing fails to[A] trace distant ancestors.[B] rebuild reliable bloodlines.[C] fully use genetic information.[D] achieve the claimed accuracy.29. In the last paragraph, a problem commercial genetic testing faces is[A] disorganized data collection.[B] overlapping database building.[C] excessive sample comparison.[D] lack of patent evaluation.30. An appropriate title for the text is most likely to be[A] Fors and Againsts of DNA Testing.[B] DNA Testing and Its Problems.[C] DNA Testing Outside the Lab.[D] Lies Behind DNA Testing.Text 3The relationship between formal education and economic growth in poor countries is widely misunderstood by economists and politicians alike. Progress in both areas is undoubtedly necessary for the social, political and intellectual development of these and all other societies; however, the conventional view that education should be one of the very highest priorities for promoting rapid economic development in poor countries is wrong. We are fortunate that it is, because building new educational systems there and putting enough people through them toimprove economic performance would require two or three generations. The findings of a research institution have consistently shown that workers in all countries can be trained on the job to achieve radical higher productivity and, as a result, radically higher standards of living.Ironically, the first evidence for this idea appeared in the United States. Not long ago, with the country entering a recession and Japan at its pre-bubble peak, the U.S. workforce was derided as poorly educated and one of the primary causes of the poor U.S. economic performance. Japan was, and remains, the global leader in automotive-assembly productivity. Yet the research revealed that the U.S. factories of Honda, Nissan, and Toyota achieved about 95 percent of the productivity of their Japanese counterparts as a result of the training that U.S. workers received on the job.More recently, while examining housing construction, the researchers discovered that illiterate, non-English-speaking Mexican workers in Houston, Texas, consistently met best-practice labor productivity standards despite the complexity of the building industry‘s work.What is the real relationship between education and economic development? We have to suspect that continuing economic growth promotes the development of education even when governments don‘t force it. After all, that‘s how education got started. When our ancestors were hunters and gatherers 10,000 years ago, they didn‘t have time to wonder much about anything besides finding food. Only when humanity began to get its food in a more productive way was there time for other things.As education improved, humanity‘s productivity potential increased as well. When the competitive environment pushed our ancestors to achieve that potential, they could in turn afford more education. This increasingly high level of education is probably a necessary, but not a sufficient, condition for the complex political systems required by advanced economic performance. Thus poor countries might not be able to escape their poverty traps without political changes that may be possible only with broader formal education. A lack of formal education, however, doesn‘t constrain the ability of the developing world‘s workforce to substantially improve productivity for the foreseeable future. On the contrary, constraints on improving productivity explain why education isn‘t developing more quickly there than it is.31. The author holds in Paragraph 1 that the importance of education in poor countries[A] is subject to groundless doubts.[B] has fallen victim of bias.[C] is conventionally downgraded.[D] has been overestimated.32. It is stated in Paragraph 1 that the construction of a new education system[A] challenges economists and politicians.[B] takes efforts of generations.[C] demands priority from the government.[D] requires sufficient labor force.33.A major difference between the Japanese and U.S workforces is that[A] the Japanese workforce is better disciplined.[B] the Japanese workforce is more productive.[C] the U.S workforce has a better education.[D] the U.S workforce is more organized.34. The author quotes the example of our ancestors to show that education emerged[A] when people had enough time.[B] prior to better ways of finding food.[C] when people on longer went hungry.[D] as a result of pressure on government.35. According to the last paragraph, development of education[A] results directly from competitive environments.[B] does not depend on economic performance .[C] follows improved productivity.[D] cannot afford political changes.Text 4The most thoroughly studied intellectuals in the history of the New World are the ministers and political leaders of seventeenth-century New England. According to the standard history of American philosophy, nowhere else in colonial America was ―so much importance attached to intellectual pursuits.‖ According to many books and articles, New England‘s leaders establi shed the basic themes and preoccupations of an unfolding, dominant Puritan tradition in American intellectual life.To take this approach to the New Englanders normally means to start with the Puritans‘ theological innovations and their distinctive ideas about the church --- important subjects that we may not neglect. But in keeping with our examination of southern intellectual life, we may consider the original Puritans as carriers of European culture, adjusting to New World circumstances. The New England colonies were the scenes of important episodes in the pursuit of widely understood ideals of civility and virtuosity.The early settlers of Massachusetts Bay included men of impressive education and influence in England. Besides the ninety or so learned ministers who came to Massachusetts church in the decade after 1629, there were political leaders like John Winthrop, an educated gentleman, lawyer, and official of the Crown before he journeyed to Boston. These men wrote and published extensively, reaching both New World and Old World audiences, and giving New England an atmosphere of intellectual earnestness.We should not forget, however, that most New Englanders were less well educated. While few craftsmen or farmers, let alone dependents and servants, left literary compositions to be analyzed, it is obvious that their views were less fully intellectualized. Their thinking often had a traditional superstitions quality. A tailor named John Dane, who emigrated in the late 1630s, left an account of his reasons for leaving England that is filled with signs. Sexual confusion, economic frustrations, and religious hope --- all came together in a decisive moment when he opened the Bible, told his father that the first line he saw would settle his fate, and read the magical words: ―come out from among them, touc h no unclean thing, and I will be your God and you shall be my people.‖ One wonders what Dane thought of the careful sermons explaining the Bible t hat he heard in Puritan churches.Meanwhile, many settler s had slighter religious commitments than Dane‘s, as one clergymanlearned in confronting folk along the coast who mocked that they had not come to the New World for religion. ―Our main end was to catch fish.‖36. The author holds that in the seventeenth-century New England[A] Puritan tradition dominated political life.[B] intellectual interests were encouraged .[C] Politics benefited much from intellectual endeavors.[D] intellectual pursuits enjoyed a liberal environment.37. It is suggested in Paragraph 2 that New Englanders[A] experienced a comparatively peaceful early history.[B] brought with them the culture of the Old World.[C] paid little attention to southern intellectual life.[D] were obsessed with religious innovations.38. The early ministers and political leaders in Massachusetts Bay[A] were famous in the New World for their writings.[B] gained increasing importance in religious affairs.[C] abandoned high positions before coming to the New World.[D] created a new intellectual atmosphere in New England.39. The story of John Dane shows that less well-educated New Englanders were often[A] influenced by superstitions.[B] troubled with religious beliefs.[C] puzzled by church sermons.[D] frustrated with family earnings.40. The text suggests that early settlers in New England[A] were mostly engaged in political activities.[B] were motivated by an illusory prospect.[C] came from different backgrounds.[D] left few formal records for later reference.Part BDirections:In the following text, some sentences have been removed.

Mark your answers on ANSWER SHEET 1. (10 points)Coinciding with the groundbreaking theory of biological evolution proposed by British naturalist Charles Darwin in the 1860s, British social philosopher Herbert Spencer put forward his own theory of biological and cultural evolution. Spencer argued that all worldly phenomena, including human societies, changed over time, advancing toward perfection. 41.____________.American social scientist Lewis Henry Morgan introduced another theory of cultural evolution in the late 1800s. Morgan, along with Tylor, was one of the founders of modern anthropology. In his work, he attempted to show how all aspects of culture changed together in the evolution of societies.42._____________________.In the early 1900s in North America, German-born American anthropologist Franz Boas developed a new theory of culture known as historical particularism. Historical particularism, which emphasized the uniqueness of all cultures, gave new direction to anthropology.43._______________________ .Boas felt that the culture of any society must be understood as the result of a unique history and not as one of many cultures belonging to a broader evolutionary stage or type of culture.44.______________________.Historical particularism became a dominant approach to the study of culture in American anthropology, largely through the influence of many students of Boas. But a number of anthropologists in the early 1900s also rejected the particularist theory of culture in favor of diffusionism. Some attributed virtually every important cultural achievement to the inventions of a few, especially gifted peoples that, according to diffusionists, then spread to other cultures.45._______________________.Also in the early 1900s, French sociologist Émile Durkheim developed a theory of culture that would greatly influence anthropology. Durkheim proposed that religious beliefs functioned to reinforce social solidarity. An interest in the relationship between the function of society and culture—known as functionalism—became a major theme in European, and especially British, anthropology.[A] Other anthropologists believed that cultural innovations, such as inventions, had a single origin and passed from society to society. This theory was known as diffusionism.[B] In order to study particular cultures as completely as possible, Boas became skilled in linguistics, the study of languages, and in physical anthropology, the study of human biology and anatomy.[C] He argued that human evolution was characterized by a struggle he called the ―survival of the fittest,‖ in which weaker races and societies m ust eventually be replaced by stronger, more advanced races and societies.[D] They also focused on important rituals that appeared to preserve a people‘s social structure, such as initiation ceremonies that formally signify children‘s entrance into adul thood.[E] Thus, in his view, diverse aspects of culture, such as the structure of families, forms of marriage, categories of kinship, ownership of property, forms of government, technology, and systems of food production, all changed as societies evolved.[F]Supporters of the theory viewed culture as a collection of integrated parts that work together to keep a society functioning.[G] For example, British anthropologists Grafton Elliot Smith and W. J. Perry incorrectly suggested, on the basis of inadequate information, that farming, pottery making, and metallurgy all originated in ancient Egypt and diffused throughout the world. In fact, all of these cultural developments occurred separately at different times in many parts of the world.Part CDirections:Read the following text carefully and then translate the underlined segments into Chinese. Your translation should be written carefully on ANSWER SHEET 2. (10 points)There is a marked difference between the education which every one gets from living with others, and the deliberate educating of the young. In the former case the education is incidental; it is natural and important, but it is not the express reason of the association. (46) It may be said that the measure of the worth of any social institution is its effect in enlarging and improving experience; but this effect is not a part of its original motive. Religious associations began, for example, in the desire to secure the favor of overruling powers and to ward off evil influences; family life in the desire to gratify appetites and secure family perpetuity; systematic labor, for the most part, because of enslavement to others, etc. (47) Only gradually was the by-product of the institution noted, and only more gradually still was this effect considered as a directive factor in the conduct of the institution. Even today, in our industrial life, apart from certain values of industriousness and thrift, the intellectual and emotional reaction of the forms of human association under which the world's work is carried on receives little attention as compared with physical output.But in dealing with the young, the fact of association itself as an immediate human fact, gains in importance. (48) While it is easy to ignore in our contact with them the effect of our acts upon their disposition, it is not so easy as in dealing with adults. The need of training is too evident; the pressure to accomplish a change in their attitude and habits is too urgent to leave these consequences wholly out of account. (49) Since our chief business with them is to enable them to share in a common life we cannot help considering whether or not we are forming the powers which will secure this ability. If humanity has made some headway in realizing that the ultimate value of every institution is its distinctively human effect we may well believe that this lesson has been learned largely through dealings with the young.(50) We are thus led to distinguish, within the broad educational process which we have been so far considering, a more formal kind of education -- that of direct tuition or schooling. In undeveloped social groups, we find very little formal teaching and training. These groups mainly rely for instilling needed dispositions into the young upon the same sort of association which keeps the adults loyal to their group.Section ⅢWritingPart A51.
