39、(2021上海模拟)For several decades,there has been an extensive and organized campaign intended to generate distrust in science,funded by regulated industries and libertarian think tanks(自由主义智囊团)whose interests and beliefs are threatened by the findings of modern science.In response,scientists have tended

40、 to stress the success of science.After all,scientists have been right about most things,from the structure of the universe to the relativity of time and space.Quoting successes isnt wrong,but for many people its not persuasive.What is typically declared to be the scientific methoddevelop a supposit

41、ion,then design an experiment to test itisnt what scientists actually do.Science is active so that new methods get invented and old ones get abandoned.The scientific method doesnt always work.False theories can produce true results,so even if an experiment works,it doesnt prove that the theory it wa

42、s designed to test is true.If there is no identifiable scientific method then what is the guarantee for trust in science?The answer is the methods by which those claims are evaluated.A scientific claim is never accepted as true until it has gone through a long process of examination by fellow scient

43、ists.Until this point,scientific feedback is typically fairly friendly.But the next step is different:once the paper is ready,it is presented to a scientific journal,where things get a whole lot tougher.Editors deliberately send scientific papers to people who are not friends or colleagues of the au

44、thors,and the job of the reviewers is to find errors or other inadequacies.We call this process“peer review”because the reviewers are scientific peers but they act in the role of a superior who has both the right and the obligation to find fault.It is only after the reviewers and the editor are sati

45、sfied that any problems have been fixed that the paper is accepted for publication and enters the body of“science.”Does this process ever go wrong?Of course.Scientists are human.But if we look carefully at historical cases where science went wrong,typically there was no agreement reached by all.Some

46、 people argue that we should not trust science because scientists are“always changing their minds”.While examples of truly settled science being overturned are far fewer than is sometimes claimed,they do exist.But the beauty of this scientific process is that it explains what might otherwise appear

47、paradoxical(矛盾的):that science produces both novelty(新颖性)and stability.New observations,ideas,interpretations introduce novelty:transformative questioning leads to collective decisions and the stability of scientific knowledge.Scientists do change their minds in the face of new evidence,but this is a

48、 strength of science,not a weakness.1.Distrust in science has been found because _.A.scientists citing successes isnt persuasive for many people to some extentB.most scientists have tended to lay too much emphasis on the success of scienceC.a wide-ranging and organized campaign has been founded in s

49、ome industries and think tanksD.someones benefits and beliefs are endangered by the findings of modern science【解析】选D。细节理解题。根据第一段第一句可知,几十年来,有一个广泛的、有组织的运动,目的是产生对科学的不信任,由受管制的行业和自由主义智囊团资助,他们的利益和信仰受到现代科学发现的威胁。由此可知,人们发现对科学的不信任是因为某些人的利益和信仰受到现代科学发现的威胁,故D项正确。2.Which of the following statements will the autho

50、r agree with about a scientific method?A.A scientific method doesnt necessarily take effect because science is changing.B.A scientific method is not right because it isnt what scientists actually do.C.A successful experiment can guarantee the truthfulness of a claim by a scientific method.D.True the
