单选题Man have often been praised by being told that they were as smart as a Philadelphia lawyer. No one knows why there is something special about Philadelphia lawyers, but the expression "smart as a Philadelphia lawyer" seems to have come from a famous trial early in the 18th century. An Englishman, William S. Cosby arrived in New York as the royal governor of the province. He was a tyrant. He wanted to make money quickly and he ruled the province with no thought for the law or the rights of the people. Among those who opposed his rule was John Peter Zinger who came to America from Germany Mr. Zinger started a newspaper which praised liberty and sharply criticized the governor. Governor Cosby arrested Mr. Zinger, charged him with slander and kept him in prison for 9 months. Mr. Zinger could not find a New York lawyer to defend him because of the governor's power. But a leading lawyer from Philadelphia agreed to defend Mr. Zinger. He was Andrew Hamilton, white-haired and almost 80 years old. The trial opened, the jury chosen and charges read. At that time, the law on slander said that jury could decide only if the person accused published in the newspaper named in the charges. The question of whether words published were true or not was to be decided by the judge. Mr. Zinger told the court he was innocent. Then the lawyer from Philadelphia rose, admitted that Mr. Zinger did publish the newspaper as charged. But Mr. Hamilton continued. The publishing of a newspaper does not make a person guilty of slander. He said that words themselves must be proved false or slanderous. Otherwise Mr. Zinger is innocent. The judge warned Mr. Hamilton that he, the judge, would decide if the words were slanderous or not. Mr. Hamilton quickly turned to the jury and asked them to decide. He said that it was their right to decide whether the alleged slander was in fact the truth. In his final statement to the jury, Mr. Hamilton said the question was much bigger than the charges against Mr. Zinger. He said the question was liberty and right of people to oppose dishonesty and tyranny by speaking and writing the truth. After a brief discussion the jury declared that Mr. Zinger was not guilty and cheers broke out in the courtroom. The decision established the principle of freedom of the press in the American Colonies. Mr. Hamilton was praised as a hero. Through the fame of Mr. Zinger trial, the praise for Mr. Hamilton has spread throughout the country. And so it is believed that the expression "as smart as a Philadelphia lawyer" honors the man from Philadelphia who successfully defended the freedom of the press to print the truth.

单选题Saudi Arabia, the oil industry's swing producer, has become its flip-flopper. In February, it persuaded OPEC to cut its total production quotas by lm barrels per day (bpd), to 23.5m, as a precaution against an oil-price crash this spring. That fear has since been replaced by its opposite. The price of West Texas crude hit $40 last week, its highest since the eve of the first Iraq war, prompting concerns that higher oil prices could sap the vigour of America's recovery and compound the frailty of Europe's. On Monday May 10th, Ali al-Naimi, Saudi Arabia's energy minister, called on OPEC to raise quotas, by at least 1. 5m bpd, at its next meeting on June 3rd. Thus far, the high oil price has been largely a consequence of good things, such as a strengthening world economy, rather than a cause of bad things, such as faster inflation or slower growth. China's burgeoning economy guzzled about 6m bpd in the first quarter of this year, 15% more than a year ago, according to Goldman Sachs. Demand was also strong in the rest of Asia, excluding Japan, growing by 5.2% to 8. 1m bpd. As the year progresses, the seasonal rhythms of America's drivers will dictate prices, at least of the lighter, sweeter crudes. Americans take to the roads en masse in the summer, and speculators are driving up the oil price now in anticipation of peak demand in a few months' time. Until recently, the rise in the dollar price of oil was offset outside America and China by the fall in the dollar itself. But the currency has regained some ground in recent weeks, and the oil price has continued to rise. Even so, talk of another oil price shock is premature. The price of oil, adjusted for inflation, is only half what it was in December 1979, and the United States now uses half as much energy per dollar of output as it did in the early 1970s. But if oil cannot shock the world economy quite as it used to, it can still give it "a good kick", warns Goldman Sachs. If average oil prices for the year come in 10% higher than it forecast, it reckons GDP growth in the Group of Seven (G7) rich nations will be reduced by 0.3%, or $70 billion. The Americans are certainly taking the issue seriously. John Snow, their treasury secretary, called OPEC's February decision "regrettable", and the rise in prices since then "not helpful". Washington pays close heed to the man at the petrol pump, who has seen the average price of a gallon of unleaded petrol rise by 39 cents in the past year. And the Saudis, some mutter, pay close heed to Washington. Besides, the high oil price may have filled Saudi coffers, but it has also affronted Saudi pride. Mr. al-Naimi thinks the high price is due to fears that supply might be disrupted in the future. These fears, he says, are "unwarranted". But the hulking machinery in the Arabian desert that keeps oil flowing round the world presents an inviting target to terrorists should they tire of bombing embassies and nightclubs. (ha May 1st, gunmen killed six people in a Saudi office of ABB Lummus Global, an American oil contractor. Such incidents add to the risk premium factored into the oil price, a premium that the Saudis take as a vote of no confidence in their kingdom and its ability to guarantee the supply of oil in the face of terrorist threats.

单选题 At the Museum of Sex in New York City, artificial-intelligence researcher David Levy projected a mock image on a screen of a smiling bride in a wedding dress holding hands with a short robot groom. "Why not marry a robot? Look at this happy couple," he said to a laughing crowd. When Levy was then asked whether anyone who would want to marry a robot was deceived, his face grew serious. "If the alternative is that you are lonely and sad and miserable, is it not better to find a robot that claims to love you and acts like it loves you?" Levy responded. "Does it really matter, if you're a happier person?" In his 2007 book, Love and Sex with Robots, Levy contends that sex, love and even marriage between humans and robots are coming soon and, perhaps, are even desirable. "I know some people think the idea is totally peculiar," he says. "But I am totally convinced it's inevitable." The 62-year-old London native has not reached this conclusion on a whim. Levy's academic love affair with computing began in his last year of university, during the vacuum-tube era. That is when he broadened his horizons beyond his passion for chess. "Back then people wrote chess programs to simulate human thought processes," he recalls. He later became engrossed in writing programs to carry on intelligent conversations with people, and then he explored the way humans interact with computers, a topic for which he earned his doctorate last year from the University of Maastricht in the Netherlands. Over the decades, Levy notes, interactions between humans and robots have become increasingly personal. Whereas robots initially found work, say, building cars in a factory, they have now moved into the home in the form of Roomba the robotic vacuum cleaner and digital pets such as Tamagotchis and the Sony Aibo. Science-fiction fans have witnessed plenty of action between humans and characters portraying artificial life-forms, such as with Data from the Star Trek franchise or the Cylons from the re-imagined Battlestar Galactica. And Levy is betting that a lot of people will fall in love with such devices. Programmers can tailor the machines to match a person's interests or render them some what disagreeable to create a desirable level of friction in a relationship. "It's not that people will fall in love with an algorithm but that people will fall in love with a convincing simulation of a human being, and convincing simulations can have a remarkable effect on people," he says.

单选题Many parents complain that their teenage children are rebelling (叛逆). I wish it were so. At this age you ought to be growing away from your parents. You should be learning to stand on your own feet. But take a good look at the present rebellion. It seems that teenagers are all taking the same way of showing that they disagree with their parents. They say they want to dress as they please, but all of them wear the same clothes. They set off in new directions in music, but all of them end up listening to the same record. Their reason for thinking or acting is that the others are doing it that way. It has become harder and harder for a teenager to stand up against the popularity wave and go his or her own way. These days every teenager can learn from the advertisements what a teenager should have and be. And many of today' s parents have come to award(给予) high marks for the popularity of their children. All this adds up to a great barrier for the teenager who wants to find his or her own path. But the barrier is worth climbing over. The path is worth following. You may want to listen to classical music instead of going to a party. You may want to collect rocks when everyone else is collecting records and stamps. Well, go to it. Find yourself. Be yourself. Popularity will come with the people who respect you for who you are. That's the only kind of popularity that really counts.
