Research on animal intelligence always makes us wonder just how smart humans are. 1 the fruit-fly experiments described by Carl Zimmer in the Science Times. Fruit flies who were taught to be smarter than the average fruit fly 2 to live shorter lives. This suggests that 3 bulbs burn longer, that there is a(n) 4 in not being too bright.
Intelligence, it 5 , is a high-priced option. It takes more upkeep, burns more fuel and is slow 6 the starting line because it depends on learning — a(n) 7 process— instead of instinct. Plenty of other species are able to learn, and one of the things they’ve apparently learned is when to 8 .
Is there an adaptive value to9 intelligence? That’s the question behind this new research. Instead of casting a wistful glance 10 at all the species we’ve left in the dust I.Q.-wise, it implicitly asks what the real 11 of our own intelligence might be. This is 12 the mind of every animal we’ve ever met.
Research on animal intelligence also makes us wonder what experiments animals would 13 on humans if they had the chance. Every cat with an owner, 14 , is running a small-scale study in operant conditioning. We believe that 15 animals ran the labs, they would test us to 16 the limits of our patience, our faithfulness, our memory for locations. They would try to decide what intelligence in humans is really 17 , not merely how much of it there is. 18 , they would hope to study a(n) 19 question: Are humans actually aware of the world they live in? 20 the results are inconclusive.

Text 1
Habits 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 connotation.
So it seems paradoxical to talk about habits in the same contextas 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 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 new 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 exploring the many other possibilities.”
All of us work through problems in ways of which we’re unaware, she says. Researchers in the late 1960 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 anything,” explains M. J. Ryan, author of the 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 habit can be .
[A] predicted
[B] regulated
[C] traced
[D] guided
23. “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 2
It 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 years, 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 doing ancestry testing,” says Troy 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 line or mitochondrial DNA, which is passed down only from mothers. 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 have a lot of data from some regions and not others, so a person’s test results 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] 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 3
The 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 to improve 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 radically 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 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 — a result of the training that U.S. workers received on the job.
More recently, while examing 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 organize
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 4
The 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 established 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 e
