问答题We may not yet be conscious of the implications of the coming technological revolution in self-driving cars. But auto manufacturers and technology companies predict that by 2020, self-driving cars will be navigating public roads in countries such as the US, UK and Finland. Most autonomous vehicles will not be owned by individuals but by companies, and rented out to travelers by the hour. Self-driving is known as a way of improving traffic flows and decreasing road accidents. Advocates of this technology think that they can remove fallible and inattentive humans from behind the steering wheel. If car ownership diminishes in the age of self-driving cars, the days of car parks are numbered. Despite the upsides of this technology, some people are worried about its downsides. Hacking will be a menace. Individuals will try to dismantle their cars" software, causing accidents. Organized hackers and terrorists will seek to cause large accidents. What"s more, chaos will occur when autonomous car operators fail to charge their cars sufficiently and run out of power on busy roads.

问答题There is not much to choose between men. They are all a hotchpotch of greatness and littleness, of virtue and vice, of nobility and baseness. Some have more strength of character, or more opportunity, and so in one direction or another give their instincts freer play, but potentially they are the same. For my part, I do not think I am any better or any worse than most people, but I know that if I set down every action in my life and every thought that has crossed my mind, the world would consider me a monster of depravity. The knowledge that these reveries are common to all men should inspire one with tolerance to oneself as well as to others. It is well also if they enable us to look upon our fellows, even the most eminent and respectable, with humor, and if they lead us to take ourselves not too seriously.

问答题Questions 1～3 Contrary to popular belief, people who sleep six to seven hours a night live longer, and those who sleep eight hours or more die younger, according to the latest study ever conducted on the subject. The study, which tracked the sleeping habits of 1.1 million Americans for six years, undermines the advice of many sleep doctors who have long recommended that people get eight or nine hours of sleep every night. "There's an old idea that people should sleep eight hours a night, which has no more scientific basis than the gold at the end of the rainbow," said Daniel Kripke, a professor of psychiatry at the University of California at San Diego who led the study, published in a recent issue of the Archives of General Psychiatry. "That's an old wives' tale. " The study was not designed to answer why sleeping longer may be deleterious or whether people could extend their life span by sleeping less. But Kripke said it was possible that people who slept longer tended to suffer from sleep apnea, a condition where impaired breathing puts stress on the heart and brain. He also speculated that the need for sleep was akin to food, where getting less than people want may be better for them. The study quickly provoked cautions and criticism, with some sleep experts saying that the main problem in America's sleep habits was deprivation, not sleeping too much. "None of this says sleep kills people," said Daniel Buysse, a University of Pittsburgh psychiatrist and the immediate past president of the American Academy of Sleep Medicine. "You should sleep as much as you need to feel awake, alert and attentive the next day," Buysse added. "I'm much more concerned about people short-changing themselves on sleep than people sleeping too long. " Sleeplessness produces a variety of health consequences that were not measured in the study, critics said. "The amount of sleep you get impacts how alert you are, your risk for accidents, how you perform at work and school," said James Walsh, president of the National Sleep Foundation, a non-profit that advocates for better sleep habits. "There's much more to life than how long you live." The study used data from an extensive survey conducted by the American Cancer Society from 1992 to 1998. Women sleeping 8, 9 and 10 hours a night had 13 percent, 23 percent and 41 percent higher risk of dying, respectively, than those who slept 7 hours, the study found. Men sleeping 8, 9 and 10 hours a night had 12 percent, 17 percent and 34 percent greater risk of dying within the study period. By contrast, sleeping five hours a night increased the risk for women by only 5 percent, and for men, by 11 percent. Among people who slept just three hours a night, women had a 33 percent increase in death, and men had a 19 percent increase, compared with those who slept seven hours. Kripke, the new study's leader, pointed out that relatively few people slept so little—1 in 1,000—where as almost half of all people slept eight hours or more. The study also found that taking a sleeping pill every day increased the risk of death by 25 percent. He recommended that people should not routinely take pills to get eight hours of sleep. While acknowledging that the sleeping pills used from 1992 to 1998 were not the same pills being used today, Kripke said, "without data showing that contemporary pills are safe, these data provide the best information about whether sleeping pills are safe for long-term use. " Kripke, whose study was funded by federal tax dollars, said doctors' recommendations that everyone get eight hours of sleep a night may have been partly influenced by the drug companies that make sleeping pills. He cited a report from a public relations firm representing the medicine Ambien, which gave money to the National Sleep Foundation to alert people about an insomnia "public health crisis" as part of a marketing campaign. Both Buysse and Walsh have served as paid consultants to makers of sleeping, pills, but both denied being influenced by that role. Walsh said most researchers in the field had accepted consulting fees from the companies, because "99 percent of the funding to support this type of research is from pharmaceutical companies. " Buysse, who wrote an editorial accompanying Kripke's article, said more research was needed to pin down exactly what the connection was between sleep and the risk of death. The study relied on people's own reports of their sleeping habits, which can be faulty. When people are asked how long they sleep, they usually report how long they spend in bed, Buysse said. That could mean that people who reported sleeping eight hours were really sleeping around seven and a half hours, which would bring them into the study's lower risk category. Buysse also disagreed that sleep was like food, arguing that while people can restrict sleep, they cannot "choose" to sleep longer. Donald Bliwise, a psychologist at Emory University, in Atlanta, said studies had shown that when people were allowed to sleep however long they wanted, without cues from alarm clocks and watches, they often slept 14 to 15 hours a day for the first few days. "Everyone," Bliwise said, "walks around somewhat sleep deprived. /1.According to Kripke' s study, what might be the reason that sleeping less is healthier than sleeping longer?

问答题 Sixty-three years after U.S. forces vanquished the Japanese and planted the Stars and Stripes atop Iwo Jima's Mount Suribachi, the remote outpost in the Volcano Islands is the focus of another pitched battle. This time film directors Clint Eastwood and Spike Lee are sparring over the accuracy of Eastwood's two films about the clash, Flags of Our Fathers and Letters from Iwo Jima. Lee has claimed that by soft-pedaling the role of African Americans in the battle, Eastwood has whitewashed history. "Clint Eastwood made two films about Iwo Jima that ran for more than four hours total, and there was not one Negro actor on the screen," Lee said last month at the Cannes Film Festival. "In his version of Iwo Jima, Negro soldiers did not exist." Eastwood bristled at the charge. "Has he ever studied history? [African-American soldiers] didn't raise the flag," he countered in an interview with the British newspaper The Guardian. "If I go ahead and put an African-American actor in there, people'd go, 'This guy's lost his mind.'" Eastwood also suggested Lee should "shut his face". That didn't go down so well. Eastwood "is not my father, and we're not on a plantation either," Lee fumed. "I'm not making this up. I know history." History, as it turns out, is on both their sides. Lee is correct that African Americans played a key role in World War II, in which more than 1 million black servicemen helped topple the Axis powers. He is correct too in pointing out that African-American forces made significant contributions to the fight for Iwo Jima. An estimated 700 to 900 African Americans, trained in segregated boot camps, participated in the landmark battle, which claimed the lives of about 6,800 servicemen, nearly all Marines. Racial prejudice shunted blacks into supply roles in Iwo Jima, but that didn't mean they were safe. Under enemy fire, they braved perilous beach landings, unloaded and shuttled ammunition to the front lines and weathered Japanese onslaughts on their positions. "Shells, mortar and hand grenades don't know the difference of color," says Thomas McPhatter, an African-American Marine who hauled ammo during the battle. "Everybody out there was trying to cover their butts to survive." But Eastwood's portrayal of the battle is also essentially accurate. Flags of Our Fathers zeroes in on the soldiers who hoisted the U.S. flag on Mount Suribachi. None of the six servicemen seen in Joe Rosenthal's famous photograph—the iconic image depicts the second flag-raising attempt; the first wasn't visible to other U.S. troops on Iwo Jima—were black. (Eastwood's other film, Letters from Iwo Jima, is told largely from the perspective of Japanese soldiers.) Eastwood is also correct that black soldiers represented only a small fraction of the total force deployed on the island. That may be true, but it is not enough to placate Yvonne Latty, the author of a book about African-American veterans. Given the hazards of their mission and the virulent racism they endured—McPhatter says he has to execute his mission without giving orders to white troops, even if they were needed—Latty argues that black soldiers warrant more than fleeting inclusion in the film. Christopher Paul Moore, author of a book about black soldiers in World War II, praises Eastwood's rendering of the battle but laments the limited role it accords African Americans. "Without black labor," he says, "we would've seen a much different ending to the war." Adds Latty: "The way America learns history, unfortunately, is through movies." Eastwood poignantly memorialized a heroic chapter in American warfare. But using a wider-angle lens might have brought into sharper focus a group often elbowed to history's fringes.

问答题John Reid became home secretary because of a prison scandal. His predecessor, Charles Clarke, was forced to resign in May after admitting that some 1,000 foreign prisoners who ought to have been considered for deportation had been freed. This week Mr. Reid faced a prison crisis of his own, made worse by new figures showing that offenders released early from jail on electronic tags have committed more than 1,000 serious crimes. In theory, the jails of England and Wales can accommodate just over 80,000 people. By October 6th they were just 210 short of that limit. The obvious remedies—cramming two people into cells built for one, letting more prisoners out on probation and moving convicts far from their families—have already been taken. So, last-ditch measures were put in place this week. Some 500 police cells will be used for prisoners. Foreign convicts" appeals against deportation will no longer be contested, in order to liberate their beds. Others will be paid to go home. This is one of history"s less surprising crises. By the late 1990s Home Office statisticians were not only predicting a rapid rise in prisoner numbers, but also erring on the side of pessimism. Eight years ago, when the prison population was just above 65,000, the department predicted that it would rise to 83,000 by 2005. In 2002 the statisticians" forecasts were also too pessimistic. Yet the politicians still appear to have been caught by surprise. One reason the prisons are full is that there are more police officers—141,000, compared with 122,000 in 2000. They can now go after crimes that are hard to crack but attract long sentences, such as drug trafficking. The number of people in prison for drug offences has trebled since 1994. And, while the overall crime rate in England and Wales is improving, it may be that some criminals are worse. Cindy Barnett, a London magistrate, reckons the defendants she sees are more violent and have graver drug problems these days. That helps to explain why magistrates sent 27% of robbers straight to prison in 2004—up from just 10% in 1993. In the past few years, the Home Office has prodded judges and magistrates to punish serious, violent offenders more heavily, while encouraging them to go easier on petty thieves. The former has certainly happened: the number of life sentences has more than doubled since the early 1990s. The latter has not. Populist politicians forgot that judges tend to have fixed ideas about the relative seriousness of offences. Force them to increase sentences for murder, and they will also hand out longer terms to armed robbers. Finally, there is media pressure. Tabloid newspapers such as the Sun and the Daily Mail hound judges who pass, or even seek to justify, lenient sentences. This week the Sun accused one wig of "living in an ivory tower". Because most people"s experience of the criminal-justice system is rare and intermittent, such coverage strongly influences the public mood. Ivory towers notwithstanding, it also stings judges. Penny Derbyshire, an academic who has been following wigs for several years, says they pore over press coverage. "And many of them have wives who read the Daily Mail," she says.

问答题My Story about Love and Loss I was lucky—I found what I loved to do early in life. Woz and I started Apple in my parents" garage when I was 20. We worked hard, and in 10 years Apple had grown from just the two of us in a garage into a $2 billion company with over 4000 employees. We had just released our finest creation—the Macintosh—a year earlier, and I had just turned 30. And then I got fired. How can you get fired from a company you started? Well, as Apple grew we hired someone who I thought was very talented to run the company with me, and for the first year or so things went well. But then our visions of the future began to diverge and eventually we had a falling-out. When we did, our board of directors sided with him. So at 30 I was out. And very publicly out. What had been the focus of my entire adult life was gone, and it was devastating. I really didn"t know what to do for a few months. I felt that I had let the previous generation of entrepreneurs down—that I had dropped the baton as it was being passed to me. I met with David Packard and Bob Noyce and tried to apologize for screwing up so badly. I was a very public failure, and I even thought about running away from the valley. But something slowly began to dawn on me— I still loved what I did. The turn of events at Apple had not changed that one bit. I had been rejected, but I was still in love. And so I decided to start over. I didn"t see it then, but it turned out that getting fired from Apple was the best thing that could have ever happened to me. The heaviness of being successful was replaced by the lightness of being a beginner again, less sure about everything. It freed me to enter one of the most creative periods of my life. During the next five years, I started a company named NeXT, another company named Pixar, and fell in love with an amazing woman who would become my wife. Pixar went on to create the world"s first computer animated feature film, Toy Story , and is now the most successful animation studio in the world. In a remarkable turn of events, Apple bought NeXT, I returned to Apple, and the technology we developed at NeXT is at the heart of Apple"s current renaissance. And Laurene and I have a wonderful family together. I"m pretty sure none of this would have happened if I hadn"t been fired from Apple. It was awful tasting medicine, but I guess the patient needed it. Sometimes life hits you in the head with a brick. Don"t lose faith. I"m convinced that the only thing that kept me going was that I loved what I did. You"ve got to find what you love. And that is as true for your work as it is for your lovers. Your work is going to fill a large part of your life, and the only way to be truly satisfied is to do what you believe is great work. And the only way to do great work is to love what you do. If you haven"t found it yet, keep looking. Don"t settle. As with all matters of the heart, you"ll know when you find it. And, like any great relationship, it just gets better and better as the years roll on. So keep looking until you find it Don"t settle.
