What is the biggest city in the world？ That is， __1__ city has the largest population？ This seems like __2__ question to answer， but actually it isn't. It's actually rather difficult to say which cities __3__ the largest. There are two reasons for this difficulty. First of all， it isn't easy to determine a city's boundaries， that is， where a city ends. Nowadays， nearly all cities have a large __4__ area around them. So when we talk about the population of a city， we often mean the population of the whole metropolitan area around the city. That means that it's difficult to determine what the population of a city is because it's difficult to define what a city is. The second reason that it is difficult to __5__ the population of different cities is this： it is almost impossible to get __6__ about the population of all cities for the same year. For example， we might get an estimate of New York's population in 1979 an __7__ of Mexico City's population in 1981. So we really can't compare the numbers because the information is for __8__ different years. the population of cities changes rather quickly， especially in some cases. For example， the population of Beijing， China may increase by 5% each year， so the population figure will change rather quickly. So we can say that these are our two __9__ for comparing the populations of cities： one， it's difficult to determine the __10__ of a city， two， it is difficult to get accurate information. 1.

1. In 1637 the French philosopher-mathematician ReneDescartes predicted that it would neverBe possible to makeA machine that thinksAs humansDo. In 1950, theBritish mathematicianAndComputer pioneerAlan TuringDeclared that oneDay there wouldBeA machine thatDuplicate human intelligence in every wayAnd prove itBy passingA specialized test. In this test,AComputerAndA human hidden from view wouldBeAsked random identical questions, if theComputer were successful; the questioner wouldBe unable toDistinguish the machine from the personBy theAnswers.InspiredBy Turing's theory, the firstConference onAIConvenedAtDartmouthCollege in New Hampshire in 1956. SoonAfterwardsAnAI laboratory was startedAt Massachusetts Institute of TechnologyBy John McCarthyAnd Marvin Minsky, two of the nation's leadingAI proponents. McCarthyAlso invented theAIComputer language, Lisp;ButBy the early 1990sAI itself had notBeenAchieved. However, logic programsCalled expert systemsAllowComputers to "make,Decisions"By interpretingDataAnd selecting fromAmongAlternatives. TechniciansCan run programs used inComplex medicalDiagnosis, language translation, mineral exploration,And evenComputerDesign.MachineryCan outperform humans physically. So, too,CanComputers outperform mental functions in limitedAreas--notably in the speed of mathematicalCalculations. For example, the fastestComputersDevelopedAreAble to perform roughly 10BillionCalculations per second.But making more powerfulComputers will probably notBe the way toCreateA machineCapable of passing the Turing test.Computer programs operateAccording to set procedures, or logic steps,CalledAlgorithms (算法). InAddition, mostComputersDo serial processing: operations of recognitionAndComputationAre performed oneAtA time. TheBrain works inA mannerCalled parallel processing, performing operations simultaneously. ToAchieve simulated (模拟) parallel processing, some supercomputers haveBeen made with multiple processors to follow severalAlgorithmsAt the same time.Critics of thisApproach insist that solvingAComputationDoes not indicate understanding, somethingA person who solvedA problem would have. Human reasoning is notBased solely on rules of logic. It involves perception,Awareness, emotional preferences, values, evaluating experience, theAbility to generalizeAnd weigh options,And more. Some proponents ofA1 have, therefore, suggested thatComputers shouldBe patternedAfter the humanBrain, which essentiallyConsists ofA network of nerveCells.By the early 1990s, theClosestApproximation toAI wasA special siliconChipBuilt toBehave likeA humanBrainCell. It was modeledAfter the internal workings of neurons in the humanCerebralContext. Unlike theConventional silicon ship, which works inDigital mode, the new siliconChip works inAnalog mode, much the wayA humanBrainCell works.21. According to Turing,AComputerCan prove to have human-like intelligence inA special test if____A. theComputer givesBetterAnswersB. the questioner fails to give identical questionsC. the questionerCan't tellBetween theAnswers ofA personAndAComputerD. The questionerCan't find the person hiddenBy theComputer
