16、.00)Today we talk about the difference between a college and a university. Colleges and universities have a lot in common. They prepare young 1 for work. They provide a greater understanding of the world and its past. And they help students learn to 2 the arts and sciences. Students who attend eithe

17、r a college or a university 3 take four years to complete a program of study. But one difference is that many colleges do not offer additional study programs or support research 4 . Universities often are much larger than colleges. Universities 5 a lot of research. They offer more programs in differ

18、ent areas of study, for undergraduate and graduate students. 6 universities developed from those of the Middle Ages in Europe. The word “university“ came from the Latin “universitas“. This described a group of people organized for a common 7 . “College“ came from a Latin word with a similar meaning,

19、 “collegium“. In England, colleges were 8 to provide students with places to live. Usually each group was studying the same thing, so the word “college“ came to mean one area of study. Today, most American colleges offer an area of study called liberal arts. The liberal arts are subjects first devel

20、oped and taught in ancient Greece. They trained a person“s mind. They 9 different from subjects that were considered more 10 in everyday life. Another meaning of “college“ is a part of a university. The first American universities divided their studies into many areas and called each one a college.

22、 the potatoes in before the eggswhy not write down every 1 that needs doing, in order, then do them, checking them off as you go? That can be very helpful. The Checklist Manifesto , written by the journalist and doctor Atul Gawande, shows the importance of checklist when hospital doctors are 2 to ti

23、ck off items on checklists as they carry out routine but critical procedures. In one trial, the rate of infections from intravenous (静脉内的) drips fell from 11% of all patients to zero 3 because staff were compelled to work through a checklist of no-brainer items, such as 4 their hands. A more recent

24、study, which included UK hospitals, suggested that wider use of checklists might 5 40% of deaths during treatment. Unlike in medicine, the 6 uses of checklists in everyday lifea list for holiday packing, for instance, aren“t usually matters of life and death. The idea of making a checklist is so stu

25、pidly obvious that it seems impossible it could have so 7 an effect. But the truth is that all life, not just medicine, is 8 complex; if highly trained intensive-care specialists can forget a 9 step, it“s sure that anyone might. Besides, the step-by-step structure of checklists can narrow your 10 to

27、分数：71.00)How science goes wrongScientific research has changed the world. Now it needs to change itself.A. A simple idea underlies science: “trust, but verify“. Results should always be subject to challenge from experiment. That simple but powerful idea has generated a vast body of knowledge. Since

28、its birth in the 17th century, modern science has changed the world beyond recognition, and overwhelmingly for the better. But success can breed extreme self-satisfaction. Modern scientists are doing too much trusting and not enough verifying, damaging the whole of science, and of humanity. B. Too m

29、any of the findings are the result of cheap experiments or poor analysis. A rule of thumb among biotechnology venture-capitalists is that half of published research cannot be replicated (复制). Even that may be optimistic. Last year researchers at one biotech firm, Amgen, found they could reproduce ju

30、st six of 53 “milestone“ studies in cancer research. Earlier, a group at Bayer, a drug company, managed to repeat just a quarter of 67 similarly important papers. A leading computer scientist worries that three-quarters of papers in his subfield are nonsense. In 2000-10, roughly 80,000 patients took

31、 part in clinical trials based on research that was later withdrawn because of mistakes or improperness. What a load of rubbish C. Even when flawed research does not put people“s lives at risk-and much of it is too far from the market to do soit blows money and the efforts of some of the world“s bes

32、t minds. The opportunity costs of hindered progress are hard to quantify, but they are likely to be vast And they could be rising. D. One reason is the competitiveness of science. In the 1950s, when modern academic research took shape after its successes in the Second World War, it was still a raref

33、ied (小众的) pastime. The entire club of scientists numbered a few hundred thousand. As their ranks have swelled to 6m-7m active researchers on the latest account, scientists have lost their taste for self-policing and quality control. The obligation to “publish or perish (消亡)“ has come to rule over ac

34、ademic life. Competition for jobs is cut-throat. Full professors in America earned on average $135,000 In 2012more than judges did. Every year six freshly minted PhDs strive for every academic post. Nowadays verification (the replication of other people“s results) does little to advance a researcher

35、“s career. And without verification, uncertain findings live on to mislead. E. Careerism also encourages exaggeration and the choose-the-most-profitable of results. In order to safeguard their exclusivity, the leading journals impose high rejection rates: in excess of 90% of submitted manuscripts. T

36、he most striking findings have the greatest chance of making it onto the page. Little wonder that one in three researchers knows of a colleague who has polished a paper by, say, excluding inconvenient data from results based on his instinct. And as more research teams around the world work on a prob

37、lem, it is more likely that at least one will fall prey to an honest confusion between the sweet signal of a genuine discovery and a nut of the statistical noise. Such fake correlations are often recorded in journals eager for startling papers. If they touch on drinking wine, or letting children pla

38、y video games, they may well command the front pages of newspapers, too. F. Conversely, failures to prove a hypothesis (假设) are rarely even offered for publication, let alone accepted. “Negative results“ now account for only 14% of published papers, down from 30% in 1990. Yet knowing what is false i

39、s as important to science as knowing what is true. The failure to report failures means that researchers waste money and effort exploring blind alleys already Investigated by other scientists. G. The holy process of peer review is not all it is praised to be, either. When a prominent medical journal

40、 ran research past other experts in the field, it found that most of the reviewers failed to spot mistakes it had deliberately inserted into papers, even after being told they were being tested. If it“s broke, fix it H. All this makes a shaky foundation for an enterprise dedicated to discovering the

41、 truth about the world. What might be done to shore it up? One priority should be for all disciplines to follow the example of those that have done most to tighten standards. A start would be getting to grips with statistics, especially in the growing number of fields that screen through untold crow

42、ds of data looking for patterns. Geneticists have done this, and turned an early stream of deceptive results from genome sequencing (基因组测序) into a flow of truly significant ones. I. Ideally, research protocols (草案) should be registered In advance and monitored in virtual notebooks. This would curb t

43、he temptation to manipulate the experiment“s design midstream so as to make the results look more substantial than they are. (It is already meant to happen in clinical trials of drugs.) Where possible, trial data also should be open for other researchers to inspect and test. J. The most enlightened

44、journals are already showing less dislike of tedious papers. Some government funding agencies, including America“s National Institutes of Health, which give out $30 billion on research each year, are working out how best to encourage replication. And growing numbers of scientists, especially young o

45、nes, understand statistics. But these trends need to go much further. Journals should allocate space for “uninteresting“ work, and grant-givers should set aside money to pay for it. Peer review should be tightenedor perhaps dispensed with altogether, in favour of post-publication evaluation in the f

46、orm of appended comments. That system has worked well in recent years in physics and mathematics. Lastly, policymakers should ensure that institutions using public money also respect the rifles. K. Science still commands enormousif sometimes perplexedrespect. But its privileged status is founded on

47、the capacity to be right most of the time and to correct its mistakes when it gets things wrong. And it is not as if the universe is short of genuine mysteries to keep generations of scientists hard at work. The false trails laid down by cheap research are an unforgivable barrier to understanding.（分
