Science, in practice, depends far less on the experiments it prepares than on the prepared

ness of the minds of the men who watch the experiments. Sir Isaac Newton supposedly discovered gravity through the fall of an apple. Apples had been falling in many places for centuries and thousands of people had seen them fall. But Newton for years had been curious a- bout the cause of the orbital motion of the moon and planets. What kept them in place? Why didn’t they fall out of the sky? The fact that the apple fell down toward the earth and not up into the tree answered the question he had been asking himself about those larger fruits of the heavens, the moon and the planets.

How many men would have considered the possibility of an apple failing up into the tree? Newton did because he was not trying to predict anything. He was just wondering. His mind was ready for the unpredictable. Unpredictability is part of the essential nature of research. If you don’t have unpredictable things, you don’t have research. Scientists tend to forget this when writing their cut and dried reports for the technical journals, but history is filled with examples of it.

In talking to some scientists, particularly younger ones, you might gather the impression that they find the "scientific method" a substitute for imaginative thought. I've attended research conferences where a scientist has been asked what he thinks about the advisability of continuing a certain experiment. The scientist has frowned, looked at the graphs, and said "The data are still inconclusive." "We know that," the men from the budget office have said, "but what do you think?" Is it worthwhile going on? What do you think we might expect?" The scientist has been shocked at having even been asked to speculate.

What this amounts to, of course, is that the scientist has become the victim of his own writings. He has put forward unquestioned claims so consistently that he not only believes them himself, but has convinced industrial and business management that they are true. If experiments are planned and carried out according to plan is faithfully as the reports in the science journals medicate, then it is perfectly topical for management to expect research to produce results measurable ill dollars and cents. It is entirely reasonable for auditors to believe that scientists who know exactly where they arc going and how they will get there should not be distracted by the necessity of keeping one eye on the cash register while the other eye is on the microscope. Nor, if regularity and conformity to a standard pattern are as desirable to the scientist as the writing of his papers would appear to reflect, is management to be blamed for discriminating against the "odd balls" among re- searchers in favor of more conventional thinkers who "work well with the team".

The autor wants to prove with the example of Isaac Newton that ______.

A.inquiring minds are more important than scientific experiments

B.science advances when fruitful researches are conducted

C.scientists seldom forget the essential nature of research

D.unpredictability weighs less than prediction in scientific research

After decades of exile from U.S. courts, the science of lie detection is gaining new accep
tance. But the federal government wants to put a stop to it, and the U.S. Supreme Court has now agreed to consider a request from the Department of Justice to bar the technology from military courts.

Uncertainties surround the science of lie detection, which uses a device called polygraph. In 1991 President George Bush banned lie detector evidence in military courts. But that ban has since been overturned by the U.S. Court of Military Appeals, which ruled that it restricts defendants' rights to present evidence of their innocence.

In the past two years, some federal courts have also ruled that polygraph evidence can be heard. This follows a decision by the Supreme Court in 1993 that gave federal judges more discretion to decide on the admissibility of evidence.

A polygraph consists of monitors for pulse rate, sweating and breathing rate. The device is supposed to uncover lies by recording increases in these measures as the subject answers questions.

Critics have always argued that cunning defendants can control their physiological responses and sway polygraph results. But supporters of the technique argue that recent research has found it to be reliable. A psychologist named Charles Honts at a state university in Idaho, points to lab oratory studies, some of them being his own, in which student-subjects were offered cash to sway the test results.

This argument is rejected by Leonard Saxe, a psychologist at a Boston university. "There is a huge difference between students in a lab and a defendant", he says. Guilty defendants have time in which to rehearse their lies, and can even come to believe them to be true.

Saxe believes that the entire theoretical basis of lie detection is invalid. "It assumes you will be more nervous lying than telling the truth". But he says that for some people lies are trivial, while certain truth can be hard to swallow.

David Faigrnan of the University of California says that if the Supreme Court upholds the military appeal court's decision to allow polygraph evidence, polygraph bans would be overturned in federal courts across U.S. "That will put a big burden on judges to understand the science, and lead to a lot more' expert testimony in the courts", he predicts. The justice department fears that this will greatly increase the cost of trials.

According to the passage, which organization raised the proposal to stop the practice of lie detection evidence in military court?

A.Federal Government.

B.U.S. Supreme Court.

C.Department of Justice.

D.Military Courts.

根据下列材料,请回答 31~35 题:

In the idealized version of how science is done, facts about the world are waiting to be observed and collected by objective researchers who use the scientific method to carry out their work. But in the everyday practice of science, discovery frequently follows an ambiguous and complicated route. We aim to be objective, but we cannot escape the context of our unique life experience. Prior knowledge and interest influence what we experience, what we think our experiences mean, and the subsequent actions we take. Opportunities for misinterpretation, error, and self-deception abound.

Consequently, discovery claims should be thought of as protoscience. Similar to newly staked mining claims, they are full of potential. But it takes collective scrutiny and acceptance to transform. a discovery claim into a mature discovery. This is the credibility process, through which the individual researcher’s me, here, now becomes the community’s anyone, anywhere, anytime. Objective knowledge is the goal, not the starting point.

Once a discovery claim becomes public, the discoverer receives intellectual credit. But, unlike with mining claims, the community takes control of what happens next. Within the complex social structure of the scientific community, researchers make discoveries; editors and reviewers act as gatekeepers by controlling the publication process; other scientists use the new finding to suit their own purposes; and finally, the public (including other scientists) receives the new discovery and possibly accompanying technology. As a discovery claim works it through the community, the interaction and confrontation between shared and competing beliefs about the science and the technology involved transforms an individual’s discovery claim into the community’s credible discovery.

Two paradoxes exist throughout this credibility process. First, scientific work tends to focus on some aspect of prevailing Knowledge that is viewed as incomplete or incorrect. Little reward accompanies duplication and confirmation of what is already known and believed. The goal is new-search, not re-search. Not surprisingly, newly published discovery claims and credible discoveries that appear to be important and convincing will always be open to challenge and potential modification or refutation by future researchers. Second, novelty itself frequently provokes disbelief. Nobel Laureate and physiologist Albert Azent-Gyorgyi once described discovery as “seeing what everybody has seen and thinking what nobody has thought.” But thinking what nobody else has thought and telling others what they have missed may not change their views. Sometimes years are required for truly novel discovery claims to be accepted and appreciated.

In the end, credibility “happens” to a discovery claim – a process that corresponds to what philosopher Annette Baier has described as the commons of the mind. “We reason together, challenge, revise, and complete each other’s reasoning and each other’s conceptions of reason.”

第 31 题 According to the first paragraph, the process of discovery is characterized by its

[A] uncertainty and complexity.

[B] misconception and deceptiveness.

[C] logicality and objectivity.

[D] systematicness and regularity.

Research is commonly divided into "applied" and "pure". This classification is arbitrary a
nd loose, but what is usually meant is that applied research is a deliberate investigation of a problem of practical importance, in contradistinction to pure research done to gain knowledge for its own sake. The pure scientist may be said to accept as an act of faith that any scientific knowledge is worth pursuing for its own sake, and, if pressed, he usually claims that in most instances it is eventually found to be useful. Most of the greatest discoveries, such as the discovery of electricity, X-rays, radium and atomic energy, originated from pure research, which allows the worker to follow unexpected, interesting clues without the intention of achieving results of practical value. In applied research it is the project which is given support, whereas in pure research it is the man. However, often the distinction between pure and applied research is a superficial one as it may merely depend on whether or not the subject investigated is one of practical irnl0ortance. For example, the investigation of the life cycle of a protozoon in a pond is pure research, but if the protozoon studied is a parasite of manor domestic animal the research would be termed applied. A more fundamental differentiation, which corresponds only very roughly with the applied and pure classification is (a) that in which the. objective is given and the means of obtaining it are sought, and (b) that in which the discovery is first made and then a use for it is sought.

There exists in some circles a certain amount of intellectual snobbery and tendency to look contemptuously on applied investigation. This attitude is based on the following two false ideas: that new knowledge is only discovered by pure research while applied research merely seeks to apply knowledge already available, and that pure research is a higher intellectual activity because it requires greater scientific ability and is more difficult. Both these ideas are quite wrong. Important new knowledge has frequently arisen from applied investigation; for instance, the science of bacteriology originated largely from Pasteur's investigations of practical problem in the beer, wine and silkworm industries. Usually it is more difficult to get results in applied research than in pure research, because the worker has to stick to and solve a given problem instead of following any promising clue that may turn up. Also in applied research most riel& have already been well worked over and marry of the easy and obvious things have been done. Applied research should not be confused with the routine practice of some branch of science where only the application of existing knowledge is attempted. There is need for both pure and applied research for they tend to be complementary.

It is generally believed that in applied investigation

A.research workers follow unexpected, interesting clues.

B.scientists make a discovery first, and then try to use it.

C.it is the man rather than the project who is given support.

D.results of practical value are to be achieved.

Bilingual education in New York City was originally viewed as a transitional program that would teach foreign-born children in their native languages until they were fluent enough in English to enter the educational mainstream. But over the last 25 years, bilingual programs at many schools have become foreign-language ghettos from which many children never escape. The need to expose foreign-born students to more English during the school day—and to move them as quickly as possible into the mainstream—was underscored this week in a pair of reports, one from Mayor Rudolph Giuliani's task force on bilingual education and one form. Schools Chancellor Harold Levy.

The push to reform. bilingual education has intensified across the country since the Silicon Valley millionaire Ron K. Unz championed a ballot initiative that ended bilingual education in California two years ago. Opponents of bilingual education want it replaced with the so-called immersion method, in which students are forced to "sink or swim" in classes taught entirely in English. Immersion has at least a chance of success in the early grades, where children are mainly being taught to read and write. But it is a recipe for failure in the upper grades, where older foreign-born students must simultaneously learn English and master complex subjects like math, science and literature.

Mayor Giuliani and Schools Chancellor Levy have wisely called for reforming special education instead of dismantling it. Both reports want to end the practice of dragooning children into the system, and call on administrators to offer parents a range of choices. Instead of automatically assigning students to bilingual classes—where they take subjects like mathematics and social studies in their native languages—parents would be allowed to choose other options, including the strategy of English as a second language, in which most instruction is offered in English. Children would be moved into the mainstream as quickly as possible, preferably within three years.

But these sensible reforms have little chance of succeeding unless the city and the state act quickly to train and recruit teachers who can perform. the needed task. Nearly 30 percent of bilingual instructors are uncertified. Some have not even mastered the languages they have been hired to teach. True reform. will require dollars, determination and a qualified teacher in every classroom.

Which word can best describe the author's attitude to the two reports frequently mentioned?

A.Supportive.

B.Negative.

C.Indifferent.

D.Objective.

第5题
Many people consider the wider use of biofuels a promising way of reducing the amount of s
urplus carbon dioxide (CO2n) being pumped into the air by the world’s mechanized transport. The theory is that plants such as sugar cane, maize (corn, to Americans), oilseed rape and wheat take up CO2 during their growth, so burning fuels made from them should have no net effect on the amount of that gas in the atmosphere.

Theory, though, does not always translate into practice, and just as governments have committed themselves to the greater use of biofuels, questions are being raised about how green this form. of energy really is. The latest comes from the International Council for Science (ICSU) based in Paris.

The ICSU report concludes that, so far, the production of biofuels has aggravated rather than ameliorated global warming. In particular, it supports some controversial findings published in 2007 by Paul Crutzen of the Max Planck Institute for Chemistry in Germany. Dr. Crutzen concluded that most analyses had underestimated the importance to global warming of a gas called nitrous oxide (N2nO). The amount of this gas released by farming biofuel crops such as maize and rape probably negates by itself any advantage offered by reduced emissions of CO2n.

Although N2nO is not common in the Earth’s atmosphere, it is a more potent greenhouse gas than CO2n and it hangs around longer. The result is that, over the course of a century, its ability to warm the planet is almost 300 times that of an equivalent mass of CO2n.

N2nO is made by bacteria that live in soil and water and, these days, their raw material is often the nitrogen-rich fertiliser that modern farming requires. Since the 1960s the amount of fertiliser used by farmers has increased sixfold, and not all of that extra nitrogen ends up in their crops. Maize, in particular, is described by experts in the field as a “nitrogen-leaky” plant because it has shallow roots and takes up nitrogen for only a few months of the year. This would make maize (which is one of the main sources of biofuel) a particularly bad contributor to global N2nO emissions.

But it is not just biofuels that are to blame. The ICSU report suggests N2nO emissions in general are probably more important than had been realised. Previous studies, including those by the International Panel on Climate Change (IPCC), a United Nations-appointed body of experts, may have miscalculated their significance — and according to Adrian Williams of Cranfield University, in Britain, even the IPCC’s approach suggests that the global-warming potential of most of Britain’s annual crops is dominated by N2nO emissions.

Biofuels are appreciated by governments because

A.burning biofuels does not add CO2n to the atmosphere.

B.biofuels can slow down the pace of global warming.

C.biofuels is a promising and profitable form. of green energy.

D.burning biofuels discharges less N2nO than burning oils.
