单选题Some people do not like anything to be out of place; they are never late for work; they return their books on time to the library; they remember people's birthdays; and they pay their bills as soon as they arrive. Mr. Hill is such a man. Mr. Hill works in a bank, and lives alone. The only family he has is in the next town: his sister lives there with her husband, and her son, Jack. Mr. Hill does not see his sister, or her family, from one year to the next, but he sends them Christmas cards, and he has not forgotten one of Jack's seventeen birthdays. Last week Mr. Hill had quite a surprise. He drove home from the bank at the usual time, driving neither too slowly nor too fast; he parked his car where he always parked it, out of the way of other cars, and he went inside to make his evening meal. Just then, there was a knock at the door. He opened the door, to find a policeman standing on the door-step. "What have I done wrong?" Mr. Hill asked himself. "Have I driven on the wrong side of the road? Has there been some trouble at the bank? Have I forgotten to pay an important bill?" "Hello, Uncle," said the policeman, "My name is Jack./

单选题 If our solar system has a Hell, it's Venus. The air is choked with foul and corrosive sulfur, heaved from ancient volcanoes and feeding acid clouds above. Although the second planet is a step farther from the sun than Mercury, a runaway greenhouse effect makes it hotter indeed. It's the hottest of the nine plants, a toasty 900 degrees Fahrenheit of baking rocky flats from equator to poles. All this under a crushing atmospheric pressure 90 times that of where you're sitting now. From the earthly perspective, a dead end. It must be lifeless. 'Venus has nothing,' is the blunt word from planetologist Kevin Zahnle of NASA Ames Research Center in California's Silicon Valley. 'We've written it off.' Yet a small group of advanced life-forms on Earth begs to differ, and theorizes that bizarre microbial ecosystems might have once populated Veuns and, in fact, may be there still. Members of this loose band of researchers suggest that their colleagues have water too much on the brain, and are, in a sense, H2O chauvinists (盲目的爱国者). 'Astrobiologists are neglecting Venus due more to narrow thinking than actual knowledge of the environment, or environments, where life can thrive,' says Dirk Schulze-Makuch, a geobiologist at the University of Texas at El Paso who recently co-authored a Venus-boosting paper in Astrobiology with colleague Louis Irwin. The bias against life on Venus is partly rooted in our own biology. Human experience instructs that liquid water, preferably lot of it, is essential for life. In search for extraterrestrial life, we obsess over small rivers in Mars' surface apparently carved by ancient gushes of water, and delight in hints of permafrost (永久冻结带) just underneath its surface. (By comparison, Venus isn't even that interesting to look at: A boring cue ball (台球的白色母球) for backyard astronomers, its clouds reflects 75% of visible light.) Attention and then funding follow the water: Three more landers will depart for Mars this spring, and serious plans for sample-return missions hover in the midterm future. 'If you have limited resources, you base exploration on what you know,' says Arizona State University planetary geologist Ronal Greeley. It's like losing your keys on the way home at night: The first place you look is under the streetlights not because they're more likely to be there, but because if they are, you'll spot them. For astrobiologists, the streetlights are the spectral (光谱的) lines for water, and they've spotted that potential on Mars, Jupiter's moon Europa, even Neptune's moon Triton. Not on the baking rocky flats of Venus.

单选题 A. abolish B. accelerate C. ambiguity D. bring E. dispense F. evidence G. expenditure H. inquiry I. irrational J. lead K. outpace L. shift M. simply N. striking O. unanimously For the past four decades that basic tension between artificial intelligence and intelligence augmentation (增加)—A.I. versus I.A. —has been at the heart of progress in computing science as the field has produced a series of ever more powerful technologies. Now, as the pace of technological change continues to 42 , it has become increasingly possible to design computing systems that enhance the human experience, or now—in a growing number of cases—completely 43 with it. Watson is an effort by IBM researchers to advance a set of techniques used to process human language. It provides 44 evidence that computing systems will no longer be limited to responding to simple commands. Machines will increasingly be able to pick out jargon (行话) and even riddles. In attacking the problem of the 45 of human language, computer science is now closing in on what researchers refer to as the 'Paris Hilton problem' —the ability, for example, to determine whether an 46 is being made by someone who is trying to reserve a hotel in France, or 47 to pass time surfing the Internet. Traditionally, economists have argued that while new forms of automation may displace jobs in the short run, over longer periods of time economic growth and job creation have continued to 48 any job-killing technology. Over the past century and a half the 49 from being a largely agrarian (农业的) society to one in which less than 1 percent of the United States labor force is in agriculture is frequently cited as 50 of the economy's ability to reinvent itself. Rapid progress in natural language processing is beginning to 51 to a new wave of automation that promises to transform areas of the economy that have until now been untouched by technological change.
