根据下列文章,回答26~30题。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 a 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 became 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 Trey 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.

第26题:In paragraphs 1 and 2 , the text shows PTK’s

A.easy availability.

B.flexibility in pricing.

C.successful promotion.

D.popularity with households.

根据下列材料,请回答 26~30 题: Pretty in pink: adult women do not remember being so obse

根据下列材料,请回答 26~30 题:

Pretty in pink: adult women do not remember being so obsessed with the colour, yet it is pervasive in our young girls’ lives. It is not that pink intrinsically bad, but it is a tiny slice of the rainbow and, though it may celebrate girlhood in one way, it also repeatedly and firmly fused girls’ identity to appearance. Then it presents that connection, even among two-year-olds, between girls as not only innocent but as evidence of innocence. Looking around, despaired at the singular lack of imagination about girls’ lives and interests. Girls' attraction to pink may seem unavoidable, somehow encoded in their DNA, but according to Jo Paoletti, an associate professor of American Studies, it's not. Children were not colour-coded at all until the early 20th century: in the era before domestic washing machines all babies wore white as a practical matter, since the only way of getting clothes clean was to boil them. What's more, both boys and girls wore what were thought of as gender-neutral dresses. When nursery colours were introduced, pink was actually considered the more masculine colour, a pastel version of red, which was associated with strength. Blue, with its intimations of the Virgin Mary, constancy and faithfulness, symbolised femininity. It was not until the mid-1980s, when amplifying age and sex differences became a dominant children's marketing strategy, that pink fully came into its own, when it began to seem innately attractive to girls, part of what defined them as female, at least for the first few critical years. I had not realised how profoundly marketing trends dictated our perception of what is natural to kids, including our core beliefs about their psychological development. Take the toddler. I assumed that phase was something experts developed after years of research into children's behaviour: wrong. Turns out, according to Daniel Cook, a historian of childhood consumerism, it was popularised as a marketing gimmick by clothing manufacturers in the 1930s. Trade publications counselled department stores that, in order to increase sales, they should create a "third stepping stone" between infant wear and older kids' clothes. It was only after "toddler" became common shoppers' term that it evolved into a broadly accepted developmental stage. Splitting kids, or adults, into ever-tinier categories has proved a sure-fire way to boost profits. And one of the easiest ways to segment a market is to magnify gender differences – or invent them where they did not previously exist.

第 26 题 By saying "it is ... The rainbow"(line 3, Para 1), the author means pink _______.

A should not be the sole representation of girlhood

B should not be associated with girls' innocence

C cannot explain girls' lack of imagination

D cannot influence girls' lives and interests

根据下列文章,回答26~30题。It used to be so straightforward. A team of researchers working t
ogether in the laboratory would submit the results of their research to a journal. A journal editor would then remove the authors names and affiliations from the paper and send it to their peers for review. Depending on the comments received, the editor would accept the paper for publication or decline it. Copyright rested with the journal publisher, and researchers seeking knowledge of the results would have to subscribe to the journal.

No longer. The Internet and pressure from funding agencies, who are questioning why commercial publishers are making money from government-funded research by restricting access to it- is making access to scientific results a reality. The Organization for Economic Co-operation and Development (OECD) has just issued a report describing the far-reaching consequences of this. The report, by John Houghton of Victoria University in Australia and Graham Vickery of the OECD, makes heavy reading for publishers who have, so far, made handsome profits. But it goes further than that. It signals a change in what has, until now, been a key element of scientific endeavor.

The value of knowledge and the return on the public investment in research depends, in part, upon wide distribution and ready access. It is big business. In America, the core scientific publishing market is estimated at between $7 billion and $11 billion. The International Association of Scientific, Technical and Medical Publishers says that there are more than 2,000 publishers worldwide specializing in these subjects. They publish more than 1.2 million articles each year in some 16,000 journals.

This is now changing. According to the OECD report, some 75% of scholarly journals are now online. Entirely new business models are emerging; three main institutional subscribers pay for access to a collection of online journal titles through site-licensing agreements. There is open-access publishing, typically supported by asking the author (or his employer) to pay for the paper to be published. Finally, there are open-access archives, where organizations such as universities or international laboratories support institutional repositories. Other models exist that are hybrids of these three, such as delayed open-access, where journals allow only subscribers to read a paper for the first six months, before making it freely available to everyone who wishes to see it. All this could change the traditional form. of the peer-review process, at least for the publication of papers.

第26题:In the first paragraph, the author discusses

A.the background information of journal editing.

B.the publication routine of laboratory reports.

C.the relations of authors with journal publishers.

D.the traditional process of journal publication

根据下列文章,请回答 21~25 题。

Text 1

In the 1920s demand for American farm products fell, as European countries began to recover from World War I and instituted austerity (紧缩) programs to reduce their imports. The result was a sharp drop in farm prices. This period was more disastrous for farmers than earlier times had been, because farmers were no longer self-sufficient. They were paying for machinery, seed, and fertilizer, and they were also buying consumer goods. The prices of the items farmers bought remained constant, while prices they received for their products fell. These developments were made worse by the Great Depression, which began in 1929 and extended throughout the 1939s.

In 1929, under President Herbert Hoover, the Federal Farm Board was organized. It established the principle of direct interference with supply and demand, and it represented the first national commitment to provide greater economic stability for farmers. President Hoover' s successor attached even more importance to this problem. One of the first measures proposed by President Franklin D. Roosevelt when he took office in 1933 was the Agricultural Adjustment Act, which was subsequently passed by Congress. This law gave the Secretary of Agriculture the power to reduce production through voluntary agreements with farmers who were paid to take their land out of use.A deliberate scarcity of farm, products was planned in an effort to raise prices. This law was declared unconstitutional by the Supreme Court on the grounds that general taxes were being collected to pay one special group of people.However, new laws were passed immediately that achieved the same result of resting soil and providing flood-control measures, but which were based on the principle of soil conservation. The Roosevelt Administration believed that rebuilding the nation' s soil was in the national interest and Was not simply a plan to help farmers at the expense of other citizens. Later the government guaranteed loans to farmers so that they could buy farm machinery, hybrid (杂交)grain, and fertilizers.

第 21 题 What brought about the decline in the demand for American farm products?

A.The impact of the Great Depression.

B.The shrinking of overseas markets.

C.The destruction caused by WWI.

D.The increased exports of European countries.

根据下列文章,回答26~30题。For the past several years, the Sunday newspaper supplement Parad
e has featured a column called “Ask Marilyn.” People are invited to query Marilyn vos Savant, who at age 10 had tested at a mental level of someone about 23 years old; that gave her an IQ of 228-the highest score ever recorded. IQ tests ask you to complete verbal and visual analogies, to envision paper after it has been folded and cut, and to deduce numerical sequences, among other similar tasks. So it is a bit confusing when vos Savant fields such queries from the average Joe (whose IQ is 100) as, What's the difference between love and fondness? Or what is the nature of luck and coincidence? It's not obvious how the capacity to visualize objects and to figure out numerical patterns suits one to answer questions that have eluded some of the best poets and philosophers.

Clearly, intelligence encompasses more than a score on a test. Just what does it means to be smart? How much of intelligence can be specified, and how much can we learn about it from neurology, genetics, computer science and other fields?

The defining term of intelligence in humans still seems to be the IQ score, even though IQ tests are not given as often as they used to be. The test comes primarily in two forms: the Stanford-Binet Intelligence Scale and the Wechsler Intelligence Scales (both come in adult and children's version)。 Generally costing several hundred dollars, they are usually given only by psychologists, although variations of them populate bookstores and the World Wide Web. Superhigh scores like vos Savant’s are no longer possible, because scoring is now based on a statistical population distribution among age pecks, rather tan simply dividing the mental are by the chronological age and multiplying by 100. Other standardized tests, such as the Scholastic Assessment Test (SAT) and the Graduate Record Exam (GRE), capture the main aspects of IQ tests.

Such standardized tests may not assess all the important elements necessary to succeed in school and in life, argues Robert J. Sternberg. In his article “How Intelligent Is Intelligence Testing?”。 Sternberg notes that traditional tests best assess analytical and verbal skills but fail to measure creativity and practical knowledge, components also critical to problem solving and life success. Moreover, IQ tests do not necessarily predict so well once populations or situations change. Research has found that IQ predicted leadership sills when the tests were given under low-stress conditions, but under high-stress conditions. IQ was negatively correlated with leadership-that is it predicted the opposite. Anyone who bas toiled through SAT will testify that test-taking skill also matters, whether it‘s knowing when to guess or what questions of skip.

第26题:Which of the following may be required in an intelligence test?

A.Answering philosophical questions.

B.Folding or cutting paper into different shapes.

C.Telling the differences between certain concepts.

D.Choosing words or graphs similar to the given ones.

根据下列文章回答,21~25题。 Habits are a funny thing. We reach for them mindlessly, setti

根据下列文章回答,21~25题。

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 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 synaptic 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 ingrain 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 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 anything,” 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.

第 21 题 In Wordsworth’s view,“habits” is characterized by being

A.casual.

B.familiar.

C.mechanical.

D.changeable.
