第1题

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

Los Angeles cabinet-maker Edward Stewart may be a modern Dr. Frankenstein. In 1959, he cla

ims, he restored a dead friend to life with a simple technique. He opened the dead man's chest, rubbed his heart with a "secret, life-giving’plant juice, then stimulated the heartbeat with 110 volts of electricity. The friend, says Stewart, has been living in Hawaii ever since.

Stewart also claims his revivification technique works on the small animals he suffocates in jars in his garage. It takes three hours to revive a dead mouse, he reports, and five hours for a small dog. "Some-times, "he adds , "I buy those little chicken hearts in the super-market, and I make them beat again using my plant juice before I cook them for dinner."

According to Stewart, he discovered the plant juice one day while cutting hedges around his former home in Hawaii. Juice from one of the plants splattered onto his wrist, he says, and he suddenly noticed the skin begin to twitch. Nonetheless, he adds, he can't reveal the name of the plant. "When the juice is zapped with electricity, "he says, "it gives off a deadly gas."

To promote his idea, Stewart has spent the past decade sending his papers to the University of California, he Army, and a number of government agencies. One scientist who evaluated the concept was Lynn Eldridge, of the Jerry Lewis Neuromuscular Research Center, in Los Angeles. She says Stewart may not be joking. "The extracts from plant like belladonna are used to supply nutrients to human organs, which must be kept alive while traveling to a transplant. So Stewart might cut the heart out of a mouse and keep it alive with plant juice. But this effect is short-lived, and the organ must be placed into a healthy body or it dies. It's impossible to place a live organ in a dead body and expect it to revive every other organ in that body. I think Stewart has observed a basic scientific phenomenon, but his interpretation is crazy."

According to the passage yon have just read, it seemed that Edward Stewart was ______.

A．a trained surgeon

B．an expert botanist

C．a skilled electrician

D．an experienced craftsman

第4题

In no small measure, the epidemic of paranormal beliefs--beliefs beyond the range of scien

tific explanation--is due to the rapid emergence of the mass media on a global scale. These media have virtually replaced the schools, colleges and universities as the chief conveyors of information. The days of the lone scientist conducting research in the lab or of the isolated scholar writing a paper or book for a limited audience have been bypassed. Today new ideas are popularized--whether half or fully baked--and they are broadcast far and wide even if they have not been sufficiently tested. Apparently the chief interests of most media corporations are entertainment rather than information, profit rather than truth, selling products rather than contributing to the sum of human knowledge. Accordingly, paranormal ideas are pandered to a gullible public and the line between fiction and reality is blurred. The public is often confronted with sensational accounts of hidden realms, and pseudoscience is mistaken for genuine existence. Even reputable publishers prefer to publish books touting paranormal claims rather than dispassionate scientific critiques. Why is it that of the thousands of proastrology, pro-psychic, or pro-UFO books published, very few are sceptical7 "They don't sell," is the response of the hallelujah choir within the publishing industry--a sad commentary on our times.

The skeptics thus have a vital role to play: to educate the public about the nature of science and to attempt to persuade media producers and directors that they have some responsibility to develop an appreciation for scientific rationality. One of the roles of CSICOP is to challenge the views of pseudoscience pouring forth daily from the media. It is clear that we cannot operate within the cloistered confines of the academy, but need to enter into the public arena. In monitoring the media, we surely have not sought to center producers or publishers; we only wish for some balance on their part in presenting paranormal claims, and for some role for scepticism about theses claims. Largely because of the media, large sectors of public opinion simply assume that psychic powers are real, that it is possible to modify material objects merely by the mind, that psychics can help detectives solve mysteries, and that we can abandon the clinical tests of medical science and heal patients by miraculous means. The number of paranormal, occult, and sci-fi television programs is increasing. Our objection is that "docudramas" are not labelled as fictionalized accounts but touted as fact. In regard to the many talk shows that constantly deal with paranormal topics, the skeptical viewpoint is rarely heard; and when it is permitted to be expressed, it is usually sandbagged by the host or other guests.

It can be inferred from the text that most people who have no doubts about paranormal phenomena are probably ______.

A．ignorant of what life really is

B．enthusiastic about mass media

C．inclined to believe things readily

D．fond of psychic powers themselves

7. Einstein and “God” The debate over Science and ...

7. Einstein and “God” The debate over Science and Religion is like catnip for anyone wanting to spout off about the improbability of God or the arrogance of scientists. The public seems to have an insatiable appetite for this debate. Many of the current debates in science and religion turn on how we define certain key words, like “God”, “transcendence”, and “religion”. A great deal also rides on how much of reality we think can be explained by another loaded word, “science.” Take the case of Albert Einstein. He died more than half a century ago, but there’s a huge debate right now between religious believers and atheists over who gets to claim Einstein, the most famous scientist of the last century. Einstein himself made a number of provocative and rather cryptic comments about religion. He called himself “a deeply religious nonbeliever.” He said, “Science without religion is lame; religion without science is blind.” Most famously, he proclaimed, “God does not play dice with the universe.” Who is this God that Einstein invoked？ Was he simply using the word “God” as a synonym for order and harmony in the universe？ I have asked a number of scientists, theologians, and Einstein scholars, and I’ve heard many different responses. “Einstein clearly was an atheist（无神论者）in the sense that he didn’t believe in a personal God,” Richard Dawkins says. “He used the word God as a metaphoric name for that which we don’t yet understand, for the deep mysteries of the universe.” The Nobel Prize-winning physicist and fellow atheist Steven Weinberg believes Einstein was just using poetic language when he talked about religion, which Weinsberg considers a mistake. “Clearly, what Einstein meant by God is so vague and so far from conventional religion, it seems to me a misuse of the word,” Weinsberg says. “The concept of God historically has had a fairly definite meaning. God was conscious. God was powerful. God was benevolent to some extent. If you’re not going to use God to mean something like that, then you shouldn’t use the word.” Walter Isaacson, Einstein’s biographer, has a very different perspective. He claims that Einstein was a deist（自然神论信仰者）who knew exactly what he was doing when he talked about “God” and “religion.” When he was asked whether he was just using the word symbolically, he said, no, he wasn’t,” Isaacson told me. “He talked about having a cosmic religion. He thought there was a spirit manifesting in the laws of the universe, and that was his notion of God.” 14. Which of the following Can Not replace the underlined word “metaphoric”？

A、Figurative.

B、Symbolic.

C、Metaphorical.

D、Historical.

第10题

Although no one is certain why migration occurs, there are several theories. One theory cl

aims that prehistoric birds of the Northern Hemisphere were forced south during the Ice Age. As the glaciers melted, the birds came back to their homelands, spent the summer, and then went south again as the ice advanced in winter. In time, the migration became a habit in spite of the disappearance of glaciers.

Another theory proposes that the ancestral home of all modern birds was the tropics. When the region became overpopulated, many species were crowded north. During the summer, there was plenty of food, but during the winter, scarcity forced them to return to the tropics.

A more recent theory suggests a relationship between increasing daylight and the stimulation of certain glands (腺) in the birds' bodies that may prepare them for migration. One scientist has been able to cause midwinter migrations by exposing birds to artificial periods of daylight. He has concluded that changes occur in the bodies of birds due to seasonal changes in the length of daylight.

According to one theory, when the glaciers disappeared, birds______.

A．stopped migrating

B．continued migrating

C．stayed in the north

D．migrated south and stayed there
