19、e OneQuestions 31 to 35 are based on the following passage.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, theyre nowhere

20、 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.The problem, the s

21、cientists 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 u

22、p with intelligence. Many of these researchers study evolution and natural adaptation instead of formal logic and conventional computer programs. 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 forefron

23、t of the field.Imitating the brains 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 expl

24、ains. But its not simply a clever network of switches. There are lots of important things going on inside the brain cells themselves. Right now, the notion that conventional computers and software are fundamentally incapable of matching the processes that take place in the brain remains controversia

25、l. 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.31.The author says that the powerful computers of today _ .A) are capable of reliably recognizing the shape of an objectB) are close to exhibiting humanlike behaviorC) are not ver

32、 contaminate the water with untreated sewage or toxic chemicals, and then release it in a devastating flood. As the emergency services struggle to respond, the terrorists strike again, shutting down the telephone network and electrical power grid with just a few mouse clicks. Businesses are paralyse

33、d, hospitals are overwhelmed and roads are gridlocked as people try to flee.This kind of scenario is invoked by doom-mongers who insist that stepping up physical security since the September 11th attacks is not enough. Road-blocks and soldiers around power stations cannot prevent digital terrorism.

34、Until we secure our cyber-infrastructure, a few keystrokes and an Internet connection is all one needs to disable the economy and endanger lives, Lamar Smith, a Texas congressman, told a judiciary committee in February. It is true that utility companies and other operators of critical infrastructure

35、 are increasingly connected to the Internet. But just because an electricity companys customers can pay their bills online, it does not necessarily follow that the companys critical control systems are vulnerable to attack. Control systems are usually kept entirely separate from other systems, for g

36、ood reason. They tend to be obscure, old-fashioned systems that are incompatible with Internet technology anyhow. On September 18th Richard Clarke, Americas cyber-security tsar, unveiled his long-awaited blueprint for securing critical infrastructure from digital attacks. It was a bit of a damp squi
