第7题:In the 1950s, the pioneers of artificial intelligenceAI) 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 ofAI researchers think they know where the field went wrong. The problem, the scientists say, is thatAI 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 inAI, 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-basedAI movement is slowly but surely moving to the forefront of the fielD、 Imitating the brain’s neural (神经的) network is a huge step in the fight direction, says computer scientist and biophysicist MichaelConrad, 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 notion that conventional computers and software are fundamentally incapable of matching the processes that take place in the brain remains controversial.But if it proves true, then the efforts ofConrad and his fellowAI rebels could turn out to be the only game in town. Which of the following is closest in meaning to the phrase "the only game in town" A、The only approach to building an artificially intelligent computer. B、The only way for them to win a prize in artificial intelligence research. C、The only area worth studying in computer science. D、The only game they would like to play in town. |

第8题:The multi-billion-dollar Western pop music industry is under fire. It is being blamed by the United Nations for the dramatic rise in drug abuse worldwide. "The most worrisome development is a culture of drug-friendliness that seems to be gaining prominence (显著)," said the UN’s 13-member International NarcoticsControlBoard in a report released in late February 1998. The 74-page study says that pop music, as a global industry, is by far the most influential trend-setter for young people of most cultures. "Some lyrics advocate the smoking of marijuana (大麻) or taking other drugs, and certain pop stars make statements and set examples as if the use of drugs for non-medicinal purposes were a normal and acceptable part of a person’s lifestyle," the study says. Surprisingly, says theBoard, the effect of drug-friendly pop music seems to survive despite the occasional shock of death by overdose (过量用药). "Such incidents tend to be seen as an occasion to mourn the loss of a role model, and not an opportunity to confront the deadly effect of ’recreational’ drug use," it notes. Since the 1970s, several internationally famous singers and movie stars—includingElvis Presley, Janice Joplin, JohnBelushi, Jimi Hendrix, Jonathan Melvin andAndy Gibbs—have died of either drug abuse or drug related illnesses. With the globalization of popular music, messages tolerating or promoting drug abuse are now reaching beyond their countries of origin. "In most countries, the names of certain pop stars have become familiar to the members of every household," the study says. The UN study also blames the media for its description of certain drug issues—especially the use of marijuana and issues of liberalization and legalization—which encourages, rather than prevents, drug abuse. "Over the last years, we have seen how drug abuse is increasingly regarded as being acceptable or even attractive," says Hamid Ghodse, president of theBoarD、"Powerful pressure groups run political campaigns aimed at legalizing controlled drugs," he says. Ghodse also points out that all these developments have created an environment which is tolerant of or even favorable to drug abuse and spoils international drug prevention efforts currently underway. The present study, be says, focuses on the issue of demand reduction and prevention within an environment that has become tolerant of drug abuse. TheBoard calls on governments to do their legal and moral duties, and to act against the pro-drug messages of the youth culture to which young people increasingly are being exposeD、 Under the influence of drug-friendly pop music, what might the youth think of the death of some pop stars caused by overdose A、They tend to mourn the pop stars as role models. B、They are shocked to know even pop stars may abuse drugs. C、They try to confront the deadly effect of "recreational" drug use. D、They may stop abusing the drugs. |
