When a Scottish research team startled the world by revealing 3 months ago that it had cloned an adult sheep, President Clinton moved swiftly. Declaring that he was opposed to using this unusual animal husbandry technique to clone humans, he ordered that federal funds not be used for such an experiment -- although no one had proposed to do so -- and asked an independent panel of experts chaired by Princeton President Harold Shapiro to report back to the White House in 90 days with recommendations for a national policy on human cloning. That group -- the National Bioethics Advisory Commission (NBAC) -- has been working feverishly to put its wisdom on paper, and at a meeting on 17 May, members agreed on a near-final draft of their recommendations.

NBAC will ask that Clinton’s 90-day ban on federal funds for human cloning be extended indefinitely, and possibly that it be made law. But NBAC members are planning to word the recommendation narrowly to avoid new restrictions on research that involves the cloning of human DNA or cells -- routine in molecular biology. The panel has not yet reached agreement on a crucial question, however, whether to recommend legislation that would make it a crime for private funding to be used for human cloning.

In a draft preface to the recommendations, discussed at the 17 May meeting, Shapiro suggested that the panel had found a broad consensus that it would be “morally unacceptable to attempt to create a human child by adult nuclear cloning.” Shapiro explained during the meeting that the moral doubt stems mainly from fears about the risk to the health of the child. The panel then informally accepted several general conclusions, although some details have not been settled.

NBAC plans to call for a continued ban on federal government funding for any attempt to clone body cell nuclei to create a child. Because current federal law already forbids the use of federal funds to create embryos (the earliest stage of human offspring before birth) for research or to knowingly endanger an embryo’s life, NBAC will remain silent on embryo research. NBAC members also indicated that they will appeal to privately funded researchers and clinics not to try to clone humans by body cell nuclear transfer. But they were divided on whether to go further by calling for a federal law that would impose a complete ban on human cloning. Shapiro and most members favored an appeal for such legislation, but in a phone interview, he said this issue was still “up in the air.”

63.We can learn from the first paragraph that ________.

[A] federal funds have been used in a project to clone humans

[B] the White House responded strongly to the news of cloning

[C] NBAC was authorized to control the misuse of cloning technique

[D] the White House has got the panel’s recommendations on cloning

64.The panel agreed on all of the following except that ________.

[A] the ban on federal funds for human cloning should be made a law

[B] the cloning of human DNA is not to be put under more control

[C] it is criminal to use private funding for human cloning

[D] it would be against ethical values to clone a human being

65.NBAC will leave the issue of embryo research undiscussed because ________.

[A] embryo research is just a current development of cloning

[B] the health of the child is not the main concern of embryo research

[C] an embryo’s life will not be endangered in embryo research

[D] the issue is explicitly stated and settled in the law

66.It can be inferred from the last paragraph that ________.

[A] some NBAC members hesitate to ban human cloning completely

[B] a law banning human cloning is to be passed in no time

[C] privately funded researchers will respond positively to NBAC’s appeal

[D] the issue of human cloning will soon be settled

Science, in practice, depends far less on the experiments it prepares than on the preparedness 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 about 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 falling 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 as faithfully as the reports in the science journals indicate, then it is perfectly logical for management to expect research to produce results measurable in dollars and cents. It is entirely reasonable for auditors to believe that scientists who know exactly where they are 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 researchers in favor of more conventional thinkers who “work well with the team.”

67.The author 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

68.The author asserts that scientists ________.

[A] shouldn’t replace “scientific method” with imaginative thought

[B] shouldn’t neglect to speculate on unpredictable things

[C] should write more concise reports for technical journals

[D] should be confident about their research findings

69.It seems that some young scientists ________.

[A] have a keen interest in prediction

[B] often speculate on the future

[C] think highly of creative thinking

[D] stick to “scientific method”

70.The author implies that the results of scientific research ________.

[A] may not be as profitable as they are expected

[B] can be measured in dollars and cents

[C] rely on conformity to a standard pattern

[D] are mostly underestimated by management
