Taxi RidingIn a moment of personal crisis, how much help can you expect from a New York taxi driver I began studying this question after watching the "Taxicab Confessions", a series of documentaries in which hidden cameras record the secrets of unsuspecting taxi riders. I found the results varied.One morning I got into three different taxis and announced: "Well, it"s my first day back in New York in seven years. I"ve been in prison." Not a single driver replied, so I tried again. "Yeah, I shot a man in Reno," I explained, hoping the driver would ask me why, so I could say casually, "Just to watch him die." But nobody asked. The only response came from a Ghanaian driver: "Reno That is in Nevada"Taxi drivers were uniformly sympathetic when I said I"d just been fired. "This is America," a Haitian driver said. "One door is closed. Another is open." He argued against my plan to burn down my boss"s house: "If you do something silly and they put you away, you cannot look for another job." A Pakistani driver even turned down a chance to profit from my loss of hope: he refused to take me to the middle of the George Washington Bridge, a $20 trip. "Why do you want to go there Go home and relax. Don"t worry. Take a new job."One very hot weekday in July, while wearing a red ski mask and holding a stuffed pillowcase with the word "BANK" on it, I tried hailing a taxi five times outside different banks. The driver picked me up every time. My ride with Guy-Caaude Thevenain, a Haitian driver, was typical of the superb assistance I received."Is anyone following us""No," said the driver, looking in his rearview mirror at traffic and me."Let"s go across the park," I said, "I just robbed the bank there. I got $25,000.""$25,000" he asked."Yeah, you think it was wrong to take it""No, man, I work 8 hours and I don"t make almost $70. If I can do that, I do it too."As we approached 86th and Lexington, I pointed to the Chemical Bank."Hey, there"s another bank," I said, "could you wait here a minute while I go inside""No, I can"t wait. Pay me now." His reluctance may have had something to do with money—taxi drivers think the rate for waiting time is too low—but I think he wanted me to learn that even a bank robber can"t expect unconditional support.

If there should be human beings on other planets, they would be radically different from Americans.
Ford"s Assembly LineWhen it comes to singling out those who have made a difference in all our lives, you cannot overlook Henry Ford. A historian a century from now might well conclude that it was Ford who most influenced all manufacturing, everywhere, even to this day, by introducing a new way to make cars—one, strange to say, that originated in slaughterhouses (屠宰场).Back in the early 1900s, slaughterhouses used what could have been called a "disassembly line". Ford reversed this process to see if it would speed up production of a part of an automobile engine called a magneto. Rather than have each worker completely assemble a magneto, one of its elements was placed on a conveyor, and each worker, as it passed, added another component to it, the same one each time. Professor David Hounshell of the University of Delaware, an expert on industrial development, tells what happened."The previous day, workers carrying out the entire process had averaged one assembly every 20 minutes. But on that day, on the line, the assembly team averaged one every 13 minutes and 10 seconds per person."Within a year, the time had been reduced to five minutes. In 1913, Ford went all the way. Hooked together by ropes, partially assembled vehicles were towed (拖、拉) past workers who completed them one piece at a time. It hasn"t been long before Ford wasturning outseveral hundred and thousand cars a year, a remarkable achievement then. And so efficient and economical was this new system that he cut the price of his cars in half, to $260, putting them within reach of all those who, up until that time, could not afford them. Soon, auto makers and the world all copied him.In fact, he encouraged them to do so by writing a book about all of his innovations, entitledToday and Tomorrow. The Age of the Automobile has arrived. Today, aided by robots and other forms of automation (自动化), everything from toasters to perfumes is made on assembly lines. The phrase "turning out" in the fourth paragraph could be best replaced by ______.

Difficult to Have Hard DiscoveriesIf there is one thing scientists have to hear, it is that the game is over. Raised on the belief of an endless voyage of discovery, they recoil (畏缩) from the suggestion that most of the best things have already been located. If they have, today"s scientists can hope to contribute no more than a few grace notes to the symphony of science.A book to be published in Britain this week,The End of Science, argues persuasively that this is the case. Its author, John Horgan, is a senior writer forScientific American magazine, who has interviewed many of today"s leading scientists and science philosophers. The shock of realizing that science might be over came to him, he says, when he was talking to Oxford mathematician and physicist Sir Roger Penrose.The End of Scienceprovoked a wave of denunciation (谴责) in the United States last year. "The reaction has been one of complete shock and disbelief," Mr. Horgan says.The real question is whether any remaining unsolved problems, of which there are plenty, lend themselves to universal solutions. If they do not, then the focus of scientific discovery is already narrowing. Since the triumphs of the 1960s—the genetic code, plate tectonics (板块构造学说), and the microwave background radiation that went a long way towards provingthe Big Bang—genuine scientific revolutions have been scarce. More scientists are now alive, spending more money on research, than ever. Yet most of the great discoveries of the 19th and 20th centuries were made before the appearance of state sponsorship, when the scientific enterprise was a fraction of its present size.Were the scientists who made these discoveries brighter than today"s That seems unlikely. A far more reasonable explanation is that fundamental science has already entered a period of diminished returns. "Look, don"t get me wrong," says Mr. Horgan. "There are lots of important things still to study, and applied science and engineering can go on forever. I hope we get a cure for cancer, and for mental disease, though there are few real signs of progress." The term "the Big Bang" in the fourth paragraph probably refers to ______.
