24.4 According to the text, which is NO mentioned as the expected disastrous results of human cloning?____(2分)
____ recent discoveries it may be necessary to revise our previous theory.
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
21.4 Nowadays, the two major parties____.
22.There is no doubt that new technologies will also play an important role in language teaching in the twenty-first century. Indeed, the use of technology in foreign language learning has constituted another important revolutionary movement in our discipline (学科）in the last half of the twentieth century. Although it has clearly not been a methodological revolution，technological innovation has played an important role in the recent history of language teaching and is bound to have a profound effect on the way that languages are taught in the future. Beginning with the introduction of filmstrips, audiotapes, and language labs in “direct method” and “audiolingual” classroom over forty years ago, technological innovation has moved from the increased use of cassette tapes, videotapes, and overhead projectors and cameras in the past several decades to the introduction of CD-ROMs and the Internet in the 1990s. The possibilities for computer-enhanced language teaching have most recently been explored in distance education programs as well as in the use of local area networks, computer-assisted reading programs, and web-based classroom activities.Though the use of technology is nothing new in foreign language teaching, its exact role in the curriculum is still being assessed and questioned, particularly in light of the rapidly changing nature of technological aids to instruction. Rather than seeing technology as just another ancillary (助手） to be added to our teaching devices, we need to evaluate its potential for enhancing classroom learning as well as for facilitating (使……便利）student-centered, independent learning outside the classroom. In using technological aids and computer-mediated (计算机为中介的）materials in instruction, we also need to bear in mind the level of proficiency of our students and their ability to benefit from the materials that can be used for them. The use of authentic materials is going to be discussed in more detail in a later section of this chapter and in subsequent chapters.(10分)22.1 This passage is mainly about____.(2分)A. the role technology plays in foreign language learningB. the role technology plays in foreign language teachingC. the role computer plays in language learning and language teachingD. the role technology plays in foreign language learning and teaching
22.5 According to the passage, if you are learning the chemical amino acid (氨基酸）in biology, what image do you take its property “acid” which means sour into?(2分)
The policeman and new mother who saved six children in the river while pregnant ______ the conference.(1分)
Leifeng always helps people without expecting anything______ .(1分)
They made friends with each other and formed a band in 1998, but then ________ after a quarrel about its future.(1分)
3.Chess must be one of the oldest games in the world. An Arab traveler in India in the year 900 wrote that it was played "long, long ago". Chess was probably invented in India, and it has been played everywhere from Japan to Europe since 1400. The name "chess" is interesting. When one player is attacking the other's king, he says, in English,"check". When the king has been caught and cannot move anywhere, he says "check mate". These words come from Persian. "Shah mat" means "the king is dead". That is when the game is over, and one player has won.Such an old game changes very slowly. The rules have not always been the same as they are now. For example, at one time the queen could only move one square at a time. Now she is the strongest piece on the board. It would be interesting to know why this has happened! Chess takes time and thought, but it is game for all kinds of people. You don't have to be a champion in order to enjoy it. It is not always played by two people sitting at the same table. The first time the Americans beat the Russians was in a match played by radio. Some of the chess masters are able to play many people at the same time. The record was when one man played 400 games! It is said that some people play chess by post. This must make chess the slowest game in the world.(5分)3.1Which of the following is known to be true?____(1分)A. Chess is an old Indian traveling game.B. Chess is the oldest game in the world.C. Chess was played in Japan and Europe before 1400.D. Chess was played in India long before 900.
