单选题The truly incompetent may never know the depths of their own incompetence, a pair of social psychologists said on Thursday．"We found again and again that people who perform poorly relative to their peers tended to think that they did rather well, "Justin KrugeL co-author of a study on the subject, said in a telephone interview． Kruger and co-author David Dunning found that when it came to a variety of skills-logical reasoning, grammar,even sense of humor--people who essentially were inept never realized it, while those who had some ability were self-critical． "It had little to do with innate modesty,"Kruger said．"but rather with a central paradox： Incompetents lack the basic skills to evaluate their performance realistically．Once they get those skills, they know where they stand, even if that is at the bottom．" "Americans and Western Europeans especially had an unrealistically sunny assessment of their own capabilities, "Dunning said by telephone in a separate interview,"while Japanese and Koreans tended to give a reasonable assessment of their performance．hi certain areas, such as athletic performance, which can be easily quantified, there is less self-delusion, the researchers said．But even in some cases in which the failure should seem obvious, the perpetrator is blithely unaware of the problem．" This was especially true in the areas of logical reasoning, where research subjects—students at Cornell University,where the two researchers were based—often rated themselves highly even when they flubbed all questions in a reasoning test． Later,when the students were instructed in logical reasoning, they scored better on a test but rate themselves lower,having learned what constituted competence in this area． Grammar was another area in which objective knowledge was helpful in determining competence, but the more subjective area of humor posed different challenges, the researchers said． Participants were asked to rate how funny certain jokes were, and compare their responses with what an expert panel of comedians thought．On average, participants overestimated their sense of humor by about 1 6 percentage points． This might be thought of as the"above-average effect", the notion that most Americans would rate themselves as above average, a statistical impossibility． The researchers also conducted pilot studies of doctors and gun enthusiasts．The doctors overestimated how well they had performed on a test of medical diagnoses and the gun fanciers thought they knew more than they actually did about gun safety． So who should be trusted：The person who admits incompetence or the one who shows confidence?Neither,according to Dunning． "You can't take them at their word．You've got to take a look at their performance，”Dunning added．

单选题City officials am considering building a path to give the public ______ to the site. A. recreation B. excess C. excursion D. access

单选题{{B}}Passage Three{{/B}} {{B}} Seniors and the City{{/B}} Tens of thousands of retirees are pulling up stakes in suburban areas and fashioning their own retirement communities in the heart of the bustling city. They are looking for what most older people want: a home with no stairs and low crime rates. And they are willing to exchange regular weekly golf time for rich cultural offerings, young neighbors and plenty of good restaurants. Spying and opportunity, major real-estate developers have broken ground on urban sites they intended to market to suburban retirees. These seniors are already changing the face of big cities. One developer, Fran McCarthy asks: "Who ever thought that suburban flight would be round trip?" The trickle of older folks returning to the city has grown into a steady stream. While some cities, especially those with few cultural offerings, have seen an exodus of seniors, urban planners say others have become retirees magnets. Between 1999 and 2000, the population of 64-to-75-year-olds in downtown Chicago rose 17 percent. Austin, New Orleans, and Los Angeles have seen double-dig-it increases as well. There may be hidden health benefits to city living. A study reveals that moving from suburbs to the city can ward off the byproduct of aging-social isolation. In the next six years, downtowns are expected to grow even grayer. For affluent retirees, city life is an increasingly popular option.
