1、一、Can the Computer Learn from ExperienceComputers have been taught to play not only checkers, but also championship chess, which is a fairly accurate yardstick for measuring the computers progress in the ability to learn from experience.Because the game requires logical reasoning, chess would seem t

2、o be perfectly suited to the computer .all a programmer has to do is give the computer a program evaluating the consequences of every possible response to every possible move, and the computer will win every time. In theory this is a sensible approach; in practice it is impossible. Today, a powerful

3、 computer can analyze 40 000 moves a second. That is an impressive speed. But there are an astronomical number of possible moves in chessliterally trillions. Even if such a program were written (and in theory it could be ,given enough people and enough time), there is no computer capable of holding

4、that much data. Therefore, if the computer is to compete at championship levels, it must be programmed to function with less than complete data. It must be able to learn from experience, to modify its own programm, to deal with a relatively unstructured situationin a word, to “think” for itself . In

5、 fact, this can be done. Chess-playing computers have yet to defeat world champion chess players, but several have beaten human players of only slightly lower ranks. The computers have had programs to carry them through the early, mechanical stages of their chess games. But they have gone on from th

6、ere to reason and learn, and sometimes to win the game. There are other proofs that computers can be programmed to learn, but this example is sufficient to demonstrate the point. Granted , winning a game of chess is not an earthshaking event even when a computer does it . But there are many serious

7、human problems which ban be fruitfully approached as games. The Defense Department uses computers to play war games and work out strategies for dealing with international tensions. Other problemsinternational and interpersonal relations , ecology and economics , and the ever-increasing threat of wor

13、ood Economy You have to have lived in the 1950s and 1960s to have experienced a good economy. In the period between 1950 and 1970 it was the rulerather than the exceptionthat an ordinary family, without higher education, could sustain itself decently on the income of a single breadwinner（养家糊口的人）. In

14、 1955, when I was 19 and living in Brooklyn, N. Y., my father, who had a sixth-grade education, maintained our family of five on a wage of $82 a week as a bookbinder. My mother taught us fairness and compassion; my father, discipline and enterprise. The U. S. economy in those years was good. Then wh

15、ere did this good economy go? It was inflated away. The price of gold, which I take as proxy for the prices of all goods, was $35 an ounce in those years. It is at roughly ten times that price today. There is another answer, though: inflation caused the entire work force to be moved into higher tax

16、groups, thus reducing after-tax purchasing power. That is, my fathers bindery job in1954 paid $82 a week, with $80 after deductions; today, at $ 820 per week the net would be $662. To ordinary people, the economy doesnt look very good at all. After-tax incomes continue to decrease in purchasing powe

17、r. The jobs offered in the employment ads pay only a little more than the minimum wage, maybe $5 an hour, which, after payroll deductions, yields $4 an hour. Compare that with minimum-wage jobs of the early 1950s, when 75 cents was worth todays $7.50 before and after taxes.Notes1 Brooklyn: a distric

24、. But common sense is useful now as it ever was. No amount of expertise substitutes for an intimate knowledge of a person or a situation. At times you just have to trust your own judgement. It almost cost me my life to learn that. I was reading a book one day, idly scratching the back of my head, wh

25、en I noticed that, in one particular spot, the scratching echoed inside my head like fingernails on an empty cardboard carton, I rushed off to my doctor. “Got a hole in your head, have you?” he teased. “Its nothingjust one of those little scalp nerves sounding off.” Two years and four doctors later,

26、 I was still being told it was nothing. To the fifth doctor. I said, almost in desperation,”But I live in tis body. I know somethings different.” “If you wont take my word for it,Ill take an X-ray and prove it to you,” he said. Well, there it was, of course, the tumor that had made a hole as big as

27、an eye socket in the back of my skull. After the operation, a young resident paused by my bed. ”Its a good thing youre so smart,” he said.” Most patient die of these tumors because we dont know theyre there until it is too late.” Im really not so smart. And Im too docile in the face of authority. I

28、should have been more aggressive with those first four doctors. Its hard to question opinions delivered with absolute certainty. Experts always sound so sure. Nevile Chamberlain, the British prime minister, was positive, just before the start of World War II, that there would be “peace for our time.

29、” Producer Irving Thalberg did not hesitate to advise Louis B. Mayer against buying the rights to Gone With the Wind because “no Civil War picture ever made a nickel.” Even Abraham Lincoln surely believed it when he said in his Gettysburg Address:” The world will little note, nor long remember, what

30、 we say here” We should not, therefore, be intimidated by experts. When its an area we really know aboutour bodies, our families, our houseslets listen to what the experts say, then make up our own minds.Notescardboard carton:a box or container made of a stiff pasteboard of paperscalp: the skin cove

Theres just one irritating detail: when you pay your money, the cashier pulls out a felt-trip marker

39、and an adhesive lapel tag and asks you your name.“Frum,” I say.“No, your first name.”“What do you need my first name for?”“To write on the tag, so all the children and the staff will know what to call you.”“In that case, write Mr. Frum.”2、 At which I am shot a look as if I had asked to be called to

40、Duke of Plaza Toro.3、 In encouraging five-year-olds to address grownups by their first names, PlaySpace is only slightly ahead of the times. As a journalist, I faithfully report that the custom of addressing strangers formally is as dead as the practice of leaving a visiting card.4、 Theres hardly a

41、secretary left who does not reply, when I give a message fro her boss, “Ill tell him you called, David.” Or a public relations agent, whether in Bangor or Bangkok, who does not begin his telephonic spiel with a cheerful “Hello, David!”5、 You dont have to be a journalist to collect amazing first-name

42、 stories. Place a collect call, and the operator first-names you. The teenager behind the counter at a fast-food restaurant asks a 70-year-old customer for his first name before taking his order.6、 Habitual first-names claim they are motivated by nothing worse than uncontrollably high-spirited frien

43、dliness. I dont believe it. I f I asked the fast-food order-takers to lend me $50, their friendliness would vanish in a whoosh. The PR man drops all his cheerfulness the moment he hears I wont go along with his story idea. No, its not friendliness that drives first-namers; its aggression. The PR age

44、nts who call me David uninvited would never, if they could somehow get him on the phone, address press baron Rupert Murdoch that way. The woman at the bank who called me David would never first-name the banks chairman. Like the mock-cheery staff at PlaySpace, they are engaged in a smiley-faced act o

45、f belittlement, an assertion of power disguised as good cheer.Notes1、 contraptions:(informal)mechanical devices;gadgets2、 felt-tip marker:软笔尖的颜色笔3、 adhesive lapel tag:不干胶标牌4 、Duke of Plaza Toro: Duke is a nobleman with the highest hereditary rank, especially in Britain.
