单选题In the late 1960's, many people in North America turned their attention to environmental problems, and new steel-and-glass skyscrapers were widely criticized. Ecologist pointed out that a cluster of tall buildings in a city often overburdens public transportation and parking lot capabilities. Skyscrapers also lavish consumers, and wasters, of electric power. In one recent year, the addition of 17 million square feet of skyscraper office space in New York City raised the peak daily demand for electricity by 120,000 kilowatts — enough to supply the entire city of Albany, New York, for a day. Glass-walled skyscrapers can be especially wasteful. The heat loss through a wall of half-inch plate glass is more than ten times that through a typical masonry wall filled with insulation board. To lessen the strain on heating and air-conditioning equipment, builders of skyscrapers have begun to use double-blazed panel of glass, and reflective glasses coasted with silver or gold mirror films that reduce glare as well as heat gain. However, mirror-walled skyscrapers raise the temperature of the surrounding air and affect neighboring buildings. Skyscrapers put a sever strain on the city's sanitation facilities, too. If fully occupied, the two World Trade Towers in New York city would alone generate 2. 25 million gallons of raw sewage each year as much as a city the size of Stanford, Connecticut, which has a population of more than 109,000. Skyscrapers also interfere with the television reception, block bird flyways, and obstruct the traffic. In Boston in the late 1960's, some people even feared that shadows from skyscrapers would kill the grass on Boston Common. Still, people continue to build skyscrapers for all the reasons they have always built them personal ambitions, civic pride and the desire of owners to have the largest possible amount of retable space.

Less Education, Income Linked to Obesity in Women, Not Men Women who are better educated and live in households that are middle-income or above are less likely to be obese than women who are less educated and live in the lowest income households, new government research shows. Among men, there is not a statistically significant【C1】______in obesity based on income and very【C2】______difference based on education, the data show. 【C3】______, about one in three U.S. adults - almost 73 million people - are obese, which is【C4】______30 or more pounds over a【C5】______weight. Extra weight raises the【C6】______of diabetes, heart disease, some types of cancer and other【C7】______. "There is a relationship between obesity and income, but it's not a【C8】______story," says Cynthia Ogden, an epidemiologist with the National Center for Health Statistics, part of the Centers for Disease Control and Prevention. "When looking at these two【C9】______of socioeconomic status - income and education - their【C10】______is greater on women than men," she says. Jennifer Lovejoy, president of the Obesity Society, says that【C11】______-income women may be more likely to become obese because of environmental【C12】______such as lack of access to safe places to do physical activity and easy access to fast food. Among the findings: 29% of women who live in households with an annual income of $77,000 or more for a family of four are obese in opposition【C13】______42% of women who live in households with an annual income below $29,000 for a family of four. 23% of women with a college degree are obese, significantly less than the 42% of women with【C14】______than a high school education. 33% of men who live in households with an annual income of $77,000 or more for a family of four are obese,【C15】______29% of men who live in households with an annual income below $29,000 for a family of four are obese. This difference is not considered statistically【C16】______. The analysis is based on【C17】______from the National Health and Nutrition Examination Survey, which is considered the gold【C18】______for evaluating obesity because it is a(an) 【C19】______survey of people whose weight and height are actually【C20】______rather than being self-reported.

Good luck. In the past,【C1】______President Bush — or at least those assigned to read his mail — what was【C2】______your mind it was necessary only to sit down at a personal computer connected to the Internet and【C3】______a note to president@whitehouse.gov. But this week, Tom Matzzie, an online organizer with the A.F.L.-C.I.O., discovered that 【C4】______with the White House had become a bit more【C5】______. When Mr. Matzzie sent an e-mail protesting【C6】______a Bush administration policy, the message was bounced back with an automated reply, saying he had to send it again in a new way. Under a system【C7】______on the White House Website【C8】______the first time last week, those who want to send a message to President Bush must now【C9】______as many as nine Web pages and【C10】______a detailed form that starts by asking whether the message sender supports White House policy【C11】______differs with it. The white House says the new e-mail system is an effort to be more responsive【C12】______the public and offer the administration "real time" access【C13】______citizen comments. Completing a message to the president also requires【C14】______a subject from the provided list, then entering a full name, organization, address and e-mail address.【C15】______the message is sent, the writer must wait for an automated response【C16】______his message,【C17】______whether the addressee intended to send the message. The message is delivered to the White House only after the person using that e-mail address【C18】______it. "Over【C19】______, it's a very cumbersome process," said Jakob Nielsen, an authority on Web design. "It's probably designed deliberately to【C20】______on their e-mail."

单选题In the 1950s, the pioneers of artificial intelligence(AI)predicted that, by the end of this century, computers would be conversing with us at work and robots would be performing our housework. But as useful as computers are, they're nowhere close to achieving anything remotely resembling these early aspirations for humanlike behavior. Never mind something as complex as conversation: the most powerful computers struggle to reliably recognize the shape of an object, the most elementary of tasks for a ten-month-old kid. A growing group of AI researchers think they know where the field went wrong. The problem, the scientists say, is that AI has been trying to separate the highest, most abstract levels of thought, like language and mathematics, and to duplicate them with logical, step-by-step programs. A new movement in AI, on the other hand, takes a closer look at the more roundabout way in which nature came up with intelligence. Many of these researchers study evolution and natural adaptation instead of formal logic and conventional computer programs. Rather than digital computers and transistors, some want to work with brain cells and proteins. The results of these early efforts are as promising as they are peculiar, and the new nature-based AI movement is slowly but surely moving to the forefront of the field. Imitating the brain's neural network is a huge step in the right direction, says computer scientist and biophysicist Michael Conrad, but it still misses an important aspect of natural intelligence. "People tend to treat the brain as if it were made up of color-coded transistors," he explains, "but it's not simply a clever network of switches. There are lots of important things going on inside the brain cells themselves. " Specifically, Conrad believes that many of the brain's capabilities stem from the pattern recognition proficiency of the individual molecules that make up each brain cell. The best way to build an artificially intelligent device, he claims, would be to build it around the same sort of molecular skills. Right now, the option that conventional computers and softwares are fundamentally incapable of matching the processes that take place in the brain remains controversial. But if it proves true, then the efforts of Conrad and his fellow AI rebels could turn out to be the only game in town.
