2 BR1- Lewis Thomas Lewis Thomas Lewis Thomas was an American physician and biologist. Thomas was born in Flushing, New York. He graduated from Princeton, and obtained his medical degree from Harvard in 1937. He held various professorships and research posts and was dean of the medical schools of New York University (1966–1969) and Yale (1972–1973), and President of Memorial Sloan-Kettering Institute. He is mostly widely known, however, for his lucid essays that combine his fascination for the living world with his thoughts on biology and philosophy. His collections of his essays include The Lives of a Cell (1974), The Medusa and the Snail (1979), and Late Night Thoughts on Listening to Mahler’s Ninth Symphony (1983).

3 circles to explain his geocentric theory of the solar system. Ptolemy’s system involved at least 80 epicycles to explain the motions of the Sun, the Moon, and the five planets known in his time. The circle was considered as the ideal orbit even if Hipparchus proposed an eccentric motion. It was only Kepler who finally showed that the planet orbits are elliptic and not spherical. BR1- Ptolemy1 Ptolemy Ptolemy lived and worked in Alexandria, Egypt, from approximately 87 to probably 170 AD. Very little is known about his personal life. Ptolemy was an astronomer, mathematician and geographer. He codified the Greek geocentric view of the universe, and rationalized the apparent motions of the planets as they were known in his time. Ptolemy synthesized and extended Hipparchus’s system of epicycles and eccentric

7 4. During 1665 to 1667, Newton conceived his ‘method of fluxions’ (infinitesimal calculus), laid the foundations for his theory of light and color, and achieved significant insight into the problem of planetary motion, which eventually led to the publication of his Principia. BR1- Sir Isaac Newton1 1. In 1642, Newton was prematurely born in Woolsthorpe. 2. In June 1661, the turning point in Newton’s life came when he left Woolsthorpe for Cambridge University. 3. In 1665, Newton took his bachelor’s degree at Cambridge without honors or distinction and then moved back temporarily to Woolsthorpe due to the Plague. Sir Isaac Newton Chronology of Sir Isaac Newton

8 BR1- Sir Isaac Newton2 5. In April 1667, Newton returned to Cambridge and, against stiff odds, was elected minor fellow at Trinity. 6. In 1666, Newton observed the fall of an apple in his garden at Woolsthorpe, later recalling, “In the same year I began to think of gravity extending to the orb of the Moon.” 7. During 1684 to 1686, Newton produced his De Motu, and Philosophiae Naturalis Principia Mathematica. 8. In 1689, he was elected to represent Cambridge in Parliament. 9. In 1696, with the help of Charles Montague, a fellow of Trinity and later earl of Halifax, Newton was appointed Warden and then Master of the Mint.

9 BR1- Sir Isaac Newton3 10. In 1703, Newton was elected president of the Royal Society and was annually reelected until his death. 11. In 1704, he published his second major work, Opticks, based largely on work completed decades before. He was knighted by Queen Anne in 1705. 12. He died in London on March 20, 1727.

10 BR1- Sir Cyril Ludowic Burt1 Sir Cyril Ludowic Burt was a British psychologist, noted for his contributions to the use of analysis in psychology and for his studies of child development. Burt was to the London City Council in 1913. He later served as professor of psychology at University College, London (1931-1950) and was knighted in 1946. After his death, Burt became a figure of. statistical ___________ educational __________ Sir Cyril Ludowic Burt Directions: Listen to the passage and fill in the blanks with what you have heard. controversy __________ appointed ________

11 BR1- Sir Gregor Mendel1 Gregor Mendel Gregor Mendel was an Austrian monk noted for his experimental work on heredity. He entered the Augustinian monastery in Brno in 1843, taught at a local secondary school, and carried out independent scientific investigations on garden peas and other plants until his election as prelate in 1868. Failing eyesight and his duties as prelate somewhat curtailed his researches. Although he anticipated Oscar Hertwig’s discovery that fertilization of an egg involved only one male sex cell, these findings went unpublished. His accounts of the experiments and his conclusions, published in 1866, were ignored during his lifetime. Rediscovered by three separate investigators in 1900, Mendel’s conclusions became the basic tenets of genetics and had a notable influence on plant growing and animal breeding.

26 GR-MAIN Global Reading 1. Part Division of the Text 2. Further Understanding For Part 1 True or False For Part 2Scanning Table Completion For Part 3 Questions For Part 4 Blank Filling For Part 5 Questions

27 GR- Part Division of the Text Part Division of the Text PartsParagraph(s)Main Ideas 1 2 3 1~2 3~4 5~6 The fact of fraudulent research has drawn much attention recently. Instances of fraudulent research both today and yesterday may seem to be a constantly spreading blot on the record of science and do damage to public confidence in the scientific method. Fraud in scientific research will inevitably lead to failure. 47~8The papers in Nature can serve as examples of how the self-monitoring system of scientific research is working. 59 There is no need to worry about fraudulent research.

28 GR-Further Understanding1 True or False T ( ) 1. The two famous scientists appeared before a congressional committee to argue against the fact that American researchers lack research ethics. F ( ) 2. The congressional committee wanted to know why there were fewer research papers published. F ( ) 3. The following three: The New York Times, Nature and Science are all technical magazines. The committee wanted to know why there are so many academic scandals in the scientific field. Nature and Science are technical periodicals, but The New York Times is newspaper.

29 GR-Further Understanding2 T ( ) 4. One of the situations related to academic scandals is that some scientists deliberately adopt the methods of fraud and plagiarism in their research. F ( ) 5. Fortunately, the self-monitoring system aimed at exposing all cases of faked data functions well. The self-monitoring system appears to be malfunctioning.

30 GR- Further Understanding3 Directions: Scan the text to find out phrases or expressions, which are related to either “unethical research behavior” or “faked data” in both Part 1 and Part 2. Para 1: fraud, plagiarism, fudging of data falsification of research, deliberate mistruth fraudulent research, cheating, bogus data falsehood, bent science, falsified synthesis, fabrication fake the result, faked data, cooked his data, plagiarize someone else’s data Para 2: Para 3: Para 4: Para 5: Scanning

31 GR- Further Understanding4 Directions: In this part, the author uses lots of examples to illustrate his points. Find all the examples used in Part 2, and fill in the following table according to their chronological order. WhenWho second century AD seventeenth- century What his unearthly data establishing the sun’s movement around the earth Ptolemy supposed example of fudging in Newton’s calculations Newton one hundred years ago small questions about the perfection of his classical generalizations about plant genetics Mendel Table Completion

32 GR- Further Understanding5 in the 1930s twenty years ago in 1974 Cyril Burtfaked data on the inheritance of intelligence in identical twins the falsified synthesis of a cellular protein a postdoctoral student at the Rockefeller Institute skin-graft fabrication at Sloan-Kettering

33 The author wants to point out that in the field of academic research, scientific malfeasance does exist, but the number is extremely small due to many factors. GR- Further Understanding6 In what kinds of cases can a scientist who has faked his research results get away with it successfully? There are two cases: one is that the faked data is confirmed by real research in every fine detail, the second one is that the work he describes is too trivial to arouse other investigators’ interest. 1. If a scientist has plagiarized others’ research paper, what would happen to him? It is definite that he would be caught by the computer retrieval system accessible to any scientific library sooner or later. 2. Why does the author mention the fact that there were only four instances of scientific malfeasance among about 18,000 research projects? 3. Questions

34 GR- Further Understanding7 Directions: In this part, the author lists five research papers. Fill in the following blanks with the information given in this part related to them. The two papers in Nature dealt with raised by Canadian scientists. They found out to suggest the phenomenon of so-called. The two papers pointed out that. In this case, no is involved. The other three papers were all about. question an important and fascinating sound evidence _____________ cautiously but not conclusively _________________________ tolerance _________ Canadian work could not be confirmed _______________________________ contrived data or misguided information ________________________________ molecular genetics ________________ _______ _______________________ Blank Filling

35 GR- Further Understanding8 Why does the author say that we don’t need to worry much about falsity and fraud appearing in academic research? Because the mainstream of scientific research is positive. Although we may face upheavals, arguments, disagreements, surprises or even total failures, we are assured that these would definitely lead to new knowledge and new bursts of research. 1. Why does the author mention the fact that the Latin root for “falsity” is the same root for the word “failure”? Because the author wants to point out that in scientific research falsity leads only to failure. 2. Questions

36 How far can we trust scientists to tell the truth? In recent years a number of cases have come to light in which researchers appear to have tampered with their results to make them fit their theories. Is such malpractice widespread or rare? Lewis Thomas reviews the evidence. TEXT

37 FALSITY AND FAILURE Lewis Thomas TEXT-S-1 Two friends of mine, eminent scientists with high responsibilities for science management and policy, were recently called before a congressional committee to testify in defense of the morals of American research. Why is it, they were asked, that there have been so many instances of outright fraud and plagiarism in recent years, so many publications of experiments never actually performed, so much fudging of data?

38 At about the same time, articles about falsification of research — particularly in biomedical science — appeared in The New York Times and in two respected and widely read technical periodicals, Nature (published in London) and Science (in Washington). The general drift of the thoughtful, worried essays was that the reported instances of deliberate mistruth on the part of scientists seem to be on the increase, and the self-monitoring system, traditionally relied upon to spot and immediately expose all cases of faked data, appears to be malfunctioning. The list of fraudulent research reports is not a long one, but several of the studies were carried out within the walls of the country’s most distinguished scientific institutions, long regarded as models of scientific probity. Science stated flat out, in its April 10, 1981, issue: “There is little doubt that a dark side of science has emerged during the past decade... Four major cases of cheating in biomedical research came to light in 1980 alone with some observers in the lay press calling it a ‘crime wave.’” TEXT-S-2

39 TEXT-S-3 It is the same list in all the reports: the case of a pathologist knowingly employing a contaminated cell-culture line, two junior researchers who plagiarized work already done by others, a clinical investigator found to have inserted bogus data on cancer chemotherapy into the project’s computer. None of these studies involved crucial issues of science; the papers in question dealt with relatively minor matters, unlikely to upheave any field but requiring, nonetheless, a significant waste of time and money in other laboratories attempting to confirm the unconfirmable. The real damage has been done to the public confidence in the scientific method, and there are apprehensions within the scientific community itself that someone, somewhere, perhaps in Washington, will begin framing new regulations to ensure exactitude and honesty in an endeavor that has always prided itself, and depended for its very progress, on these two characteristics.

40 Now that the issue has surfaced so publicly it is likely that story will lead to story, and there will be more speculations and skepticism about any piece of science that seems to carry surprising or unorthodox implications. Indeed, a number of old stories are being exhumed and revived, as though to reveal a pattern of habitual falsehood in the process of science: Ptolemy and his unearthly second-century A.D. data establishing the sun’s movement around the earth, supposed examples of seventeenth-century fudging in Newton’s calculations, even some small questions about the perfection of Gregor Mendel’s classical (and absolutely solid) generalizations about plant genetics one hundred years ago. Lumped in with these are some outright examples of bent science: Cyril Burt’s 1930s data on the inheritance of intelligence in identical twins, the falsified synthesis of a cellular protein by a postdoctoral student at the Rockefeller Institute twenty years ago, and the notorious episode of skin-graft fabrication at Sloan-Kettering in 1974. TEXT-S-4

41 It is an impossibility for a scientist to fake his results and get away with it, unless he is lucky enough to have the faked data conform, in every fine detail, to a guessed-at truth about nature (the probability of this kind of luck is exceedingly small), or unless the work he describes is too trivial to be of interest to other investigators. Either way, he cannot win. These can, if you like, be made to seem all of a piece, a constantly spreading blot on the record of science. Or, if you prefer (and I do prefer), they can be viewed as anomalies, the work of researchers with unhinged minds or, as in the cases of Newton and Mendel, gross exaggerations of the fallibility of even superb scientists. TEXT-S-5

42 TEXT-S-6 If he reports something of genuine significance, he knows for a certainty that other workers will repeat his experiments, or try to, and if he has cooked his data the word will soon be out, to the ruin of his career. If he has plagiarized someone else’s paper, the computer retrieval systems available to scientific libraries everywhere will catch him at it, sooner or later, with the same result. In short, the system does indeed work, and the fact that only four instances of scientific malfeasance have been identified in a year during which some 18,000 research projects were sponsored by the National Institutes of Health means just what the fact says: such events are extremely rare. This is not a claim that scientists are necessarily, by nature, an impeccably honest lot although I am convinced that all the best ones are. It says, simply, that people are not inclined to try cheating in a game where cheating leads almost inevitably to losing.

43 TEXT-S-7 You have only to glance through other pages of the same issue of Nature in which the editorial comment on fraud appears to catch a sense of how the system really works, and works at its very best. There are two extensive papers dealing with an important and fascinating question raised last year by a Canadian group of immunologists, who had found evidence suggesting, cautiously but not conclusively, that mice can inherit through the male line an acquired abnormality in their immune cells known technically as “tolerance”. If true, the claim would support nothing less than Lamarckianism, long since jettisoned from biology; it would be an upheaval indeed to face again, as an open problem, the question of the inheritance of acquired characteristics.

44 TEXT-S-8 The two new papers explore the matter in elegantly designed and meticulously executed experiments, with the conclusion that the Canadian work could not be confirmed. There is, in this instance, no question at all of contrived data or even the misguided reading of results; it is a typical instance of disagreement in science, something that happens whenever major ideas are under exploration. It will, in this case, lead to more work in the three laboratories now caught up in the problem and no doubt in others not yet involved. It may also lead to new knowledge, a deeper comprehension of immunology, and conceivably to something surprising, even if the Canadians turn out at the end to have been totally wrong. In the same journal there are three marvelous papers — one from the University of Cambridge, two from Cal Tech — that will cause even more of a stir in biomedical science, generating surprise, argument, and new bursts of research in laboratories around the world.

45 TEXT-S-9 The genetic composition of human mitochondria has been elucidated, and these structures, long believed to be the descendants of bacteria living as permanent lodgers inside all nucleated cells, are turning out to have an arrangement of their genes like nothing else on earth: they display an astonishing economy in their circles of DNA, and in some respects the genetic code is different from what has, up to now, been regarded as a universal code. It is something quite new, unorthodox, unexpected, and therefore certain to be challenged but also likely to be repeated, confirmed, and extended. Molecular genetics may then be moved on to new ground, new explanations for the origin of mitochondria will be thought up and tested, and science itself will be off and running in a new direction.

46 TEXT-S-10 With work like this going on in the pages of a single issue of Nature, and with similar things to be read in Science, week after week these days, I cannot find time to worry so much about falsity and fraud. Only to reflect that my dictionary gives the Latin root for “falsity” as fallere, which is the same root for the word “failure”.

47 TEXT-W-1 FALSITY AND FAILURE Lewis Thomas Two friends of mine, eminent scientists with high responsibilities for science management and policy, were recently called before a congressional committee to testify in defense of the morals of American research.

56 TEXT-S2-1 1. What does the word “drift” refer to? The word “drift” refers to “the general idea”. 2. What is the meaning of the sentence in Chinese? 那几篇经过深思熟虑且忧虑重重的文章的大意是,报刊上披露的科学家故意 捏造事实的事例似有上升趋势,长期以来赖以发现并迅速曝光各种虚假数据 的自律体系好像失灵了. 3. Why does the author use the two phrases “seem to be” and “appear to be”? The phrases “seem to be” and “appear to be” indicate uncertainty. The author uses these two phrases in order to show that the phenomenon may not necessarily happen in any scientific paper.

57 TEXT-S3-2 1. Why does the author think that the loss of public confidence is the real damage? Because maybe both time and money are needed to prove that the data is contrived or the report is faked, but if the public no longer believe any scientific report due to some faked ones, it will pose a potential danger to science and society. 2. What does the phrase “within the scientific community” refer to? This phrase refers to those scientists who do scientific research. 3. What do “these two characteristics” refer to? They refer to “exactitude and honesty”.

58 TEXT-S4-3 1. What’s the meaning of the phrase “now that”? “Now that” means “as a result of something”, for example: 2. What is the meaning of the sentence in Chinese? 由于这一问题如此公开暴露,很可能一篇报道会引出又一篇报道,大家对任 何似乎有着惊人之处或异于常规之处的科学研究都会产生更多的猜测或怀疑. Now that they’ve got to know each other a little better, they get along just fine. 由于彼此之间有了进一步了解,他们相处得不错。

59 TEXT-S5-4 1. What does “these” refer to? It refers to the examples of habitual falsehood in the process of science. 2. What does the phrase “all of a piece” mean? This phrase means “be the same or similar in all parts”. The style of the book is all of a piece, both in illustrations and text. 这本书无论是插图还是文字,风格都很一致。

60 TEXT-S5-5 Analyze the structure of the sentence. 本句是个由连接词 “ unless ” 组成的主从句,主句是 “ It is an impossibility for a scientist to fake his results and get away with it ”, 从句由两个 并列的状语从句组成: “ unless he is lucky… ”,“ or unless the work… ” 。

61 TEXT-S5-6 1. What does “either way” refer to? “Either way” refers to the following two situations: the first one is that he is lucky enough that his faked data are later to be confirmed, the second one is that no other researchers are interested in what he is doing. 2. Analyze the structure of the sentence. 本句是个倒装句,按正常语序应为: He cannot win either way. 在这里 倒装句起强调作用,强调了无论哪个方法都不行。

62 TEXT-S6-7 1. What does “it” refer to? It refers to the fact that the events of scientific malfeasance are extremely rare. 2. What does “game” refer to? It refers to “scientific research”. 3. What is the meaning of the sentence in Chinese? 这仅仅是说明,在欺骗几乎不可避免地会导致失败的游戏中,人们不会乐于 弄虚作假。
