1、科普类0:2012Text 3(科学发现声明的取信过程)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 ambiguo

2、us 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-de

3、ception 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 whic

4、h the individual researchers me, here, now becomes the communitys 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

5、 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 sci

6、entists) 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 individuals discovery claim into the commu

7、nitys 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

8、 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 disbe

9、lief. 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 fo

10、r 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 others reasoning and e

11、ach others conceptions of reason.”31. According to the first paragraph, the process of discovery is characterized by itsA uncertainty and complexity.B misconception and deceptiveness.C logicality and objectivity.D systematicness and regularity.32. It can be inferred from Paragraph 2 that credibility

12、 process requiresA strict inspection.Bshared efforts.C individual wisdom.Dpersistent innovation.33.Paragraph 3 shows that a discovery claim becomes credible after itA has attracted the attention of the general public.Bhas been examined by the scientific community.C has received recognition from edit

13、ors and reviewers.Dhas been frequently quoted by peer scientists.34. Albert Szent-Gyrgyi would most likely agree thatA scientific claims will survive challenges.Bdiscoveries today inspire future research.C efforts to make discoveries are justified.Dscientific work calls for a critical mind.35.Which

14、of the following would be the best title of the test?A Novelty as an Engine of Scientific Development.BCollective Scrutiny in Scientific Discovery.C Evolution of Credibility in Doing Science.DChallenge to Credibility at the Gate to Science.31. A 32. A 33. B 34. D 35. D1:2009Text 2(DNA检测及其存在的问题)It is

15、 a wise father that knows his own child, but today a man can boost his paternal (fatherly) wisdom or at least confirm that hes the kids dad. All he needs to do is shell our $30 for paternity testing kit (PTK) at his local drugstore and another $120 to get the results.More than 60,000 people have pur

16、chased the PTKs since they first become available without prescriptions last years, according to Doug Fog, 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 t

17、o more than $2500.Among the most popular : paternity and kinship testing , which adopted children can use to find their biological relatives and latest rage a many passionate genealogists-and supports businesses that offer to search for a familys geographic roots .Most tests require collecting cells

18、 by webbing 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

19、 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 fathers line or mitochondrial DNA, which a passed down onl

20、y 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

21、 is only as good as the reference collections to which a sample is compared. Databases used by some companies dont rely on data collected systematically but rather lump together information from different research projects. This means that a DNA database may differ depending on the company that proc

22、esses 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. 26.In paragraphs 1 and 2 , the text shows PTKs _.Aeasy availabilityBflexibility in pricing C successful promotion D popularity with hou

23、seholds27. PTK is used to _.Alocate ones birth placeBpromote genetic researchC identify parent-child kinship D choose children for adoption 28. Skeptical observers believe that ancestry testing fails to_.Atrace distant ancestors Brebuild reliable bloodlinesC fully use genetic information D achieve t

24、he claimed accuracy 29. In the last paragraph ,a problem commercial genetic testing faces is _.Adisorganized data collection Boverlapping database building C excessive sample comparisonD lack of patent evaluation30. An appropriate title for the text is most likely to be_.AFors and Againsts of DNA te

If he had played last s

26、eason, however, he would have been one of 42. The bodies playing major professional sports have changed dramatically over the years, and managers have been more than willing to adjust team uniforms to fit the growing numbers of bigger, longer frames.The trend in sports, though, may be obscuring an u

27、nrecognized reality: Americans have generally stopped growing. Though typically about two inches taller now than 140 years ago, todays people - especially those born to families who have lived in the U.S. for many generations - apparently reached their limit in the early 1960s. And they arent likely

28、 to get any taller. In the general population today, at this genetic, environmental level, weve pretty much gone as far as we can go, says anthropologist William Cameron Chumlea of Wright State University. In the case of NBA players, their increase in height appears to result from the increasingly c

29、ommon practice of recruiting players from all over the world. Growth, which rarely continues beyond the age of 20, demands calories and nutrients - notably, protein - to feed expanding tissues. At the start of the 20th century, under-nutrition and childhood infections got in the way. But as diet and

30、 health improved, children and adolescents have, on average, increased in height by about an inch and a half every 20 years, a pattern known as the secular trend in height. Yet according to the Centers for Disease Control and Prevention, average height - 59 for men, 54 for women - hasnt really chang

31、ed since 1960.Genetically speaking, there are advantages to avoiding substantial height. During childbirth, larger babies have more difficulty passing through the birth canal. Moreover, even though humans have been upright for millions of years, our feet and back continue to struggle with bipedal po

32、sture and cannot easily withstand repeated strain imposed by oversize limbs. There are some real constraints that are set by the genetic architecture of the individual organism, says anthropologist William Leonard of Northwestern University.Genetic maximums can change, but dont expect this to happen

33、 soon. Claire C. Gordon, senior anthropologist at the Army Research Center in Natick, Mass., ensures that 90 percent of the uniforms and workstations fit recruits without alteration. She says that, unlike those for basketball, the length of military uniforms has not changed for some time. And if you

34、 need to predict human height in the near future to design a piece of equipment, Gordon says that by and large, you could use todays data and feel fairly confident.31. Wilt Chamberlain is cited as an example to_.A illustrate the change of height of NBA players.B show the popularity of NBA players in

35、 the U.S.C compare different generations of NBA players.D assess the achievements of famous NBA players.32. Which of the following plays a key role in body growth according to the text?A Genetic modification. B Natural environment.C Living standards. D Daily exercise.33. On which of the following st

36、atements would the author most probably agree?A Non-Americans add to the average height of the nation.B Human height is conditioned by the upright posture.C Americans are the tallest on average in the world.D Larger babies tend to become taller in adulthood.34. We learn from the last paragraph that

37、in the near future_.A the garment industry will reconsider the uniform size.B the design of military uniforms will remain unchanged.C genetic testing will be employed in selecting sportsmen.D the existing data of human height will still be applicable.35. The text intends to tell us that_.A the chang

38、e of human height follows a cyclic pattern.B human height is becoming even more predictable.C Americans have reached their genetic growth limit.D the genetic pattern of Americans has altered.31. A 32.C 33.B 34.D 35.C3:2007年Text 2（智商测试不能准确反映人的能力）For the past several years， the Sunday newspaper supple

39、ment Parade 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 e

40、nvision 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， Whats the difference between love and fondness？ Or what is the nature of luck and coin

41、cidence？ Its 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

42、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 f

43、orms： the Stanford-Binet Intelligence Scale and the Wechsler Intelligence Scales （both come in adult and childrens 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 scor

44、es like vos Savants 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

45、 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 tes

46、ts 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 leadersh

47、ip 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 its knowing when to guess or w

48、hat questions of skip. 26. 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. 27. What can be inferred about intelligence testing from Paragraph 3？ A People no longer use IQ score
