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

2. A railroad was being built all the way down the east coast off Florida, from Jacksonville to Miami and Negro workers were employed because they were cheap. A great many of them were in Daytona. Most of them had children. They were living in shacks worse than those in The Terry in Augusta. The children were running wild in the streets. Mary Bethune seemed to hear a voice say, "What is the place? Build your school there."Her husband, Albertus, wasn't so sure about her school. He thought Palatka was a pretty good place for them to live. Mary listened but she never gave up her idea. She knew that if she went to Daytona, Albertus would come too.One day she begged a ride for herself and her little boy with a family that was going to Daytona. It was only seventy miles away. But in 1904 the sand was deep on Florida roads. Practically no one had an automobile -- certainly not the poor family that gave Mary and little Albert a ride. So it was three dusty days after they left Palatka before they reached Daytona. There Mary hunted up the only person she knew, and she and little Albert stayed with this friend for a few days.As she had done in The Terry in Augusta, Mary walked up and down the poor streets of Daytona. She was looking for two things -- a building for the school she was determined to start and some pupils for that school.After a day or two, she found an empty shack on Oak Street. She thought this would do. The owner said she could rent it for $11.00 a month. But it wasn't worth that much. The paint had peeled off, the front steps wobbled so that she had to hang onto the shaky railing to keep from falling, the house was dirty, it had a leaky roof. In most of the windows the panes of glass were broken or cracked.Eleven dollars a month ! Mary said she only had Times="10".50. She promised to pay the rent as soon as she could earn the money. The owner trusted her. By the time she was sure she could have the building, she had five little girls from the neighborhood as her pupils.What a school! A rickety old house and five little girls! The little girls pitched in and cleaned the house. The neighbors helped with scrubbing brushes, brooms, hammers, nails, and saws. Soon the cottage could be lived in, but there were no chairs, no tables, no beds. There was no stove. However, there were no pots and pans to cook in, even if there had been a stove.Mary set about changing these things. She found things in trash piles and the city dump. Nobody but Mary would have thought of making tables and chairs and desks from the old crates she picked up and brought home. Behind the hotels on the beach she found cracked dishes, old lamps, even some old clothes. She took them home too. Everything was scoured and mended and used. "Keep things clean and neat" was her motto then; and as long as she lived the pupils in her school had to live up to that motto.Her little pupils had no pencils. They wrote with pieces of charcoal made from burned logs. Their ink was elderberry juice. What good was ink or a pencil if there was no paper to write on? Mary took care of that too.Every time she went to the store to get a little food, or a few pots and pans, she had each article wrapped separately. The pieces of wrapping paper were carefully removed and smoothed out. The little girls used this paper to write their lessons with their charcoal pencils.She needed a cookstove very badly but she couldn't pay for one. What should she do? Her little pupils had to have warm food.Unexpectedly, the problem was solved for her. One day a wrinkled old white neighbor said to her, "Can you read?"Mary said, "Yes.""Then will you read me this letter from my son? I can't find my glasses."Mary read the letter to her."Thanks," said the mother.Mary turned to go. "You're welcome."The old woman stood by her open door and thought a moment. Then she said, "I got an old cookstove and I don't need it. Would you want it?"(5分)2.1 How did Mary's husband, Albertus feel about going to Daytona?____(1分)A. He was strongly in favour.B. He was quite reluctant.C. He was definitely against it.D. He was not happy about the idea.
