Berners-Lee regards today’s Web as a rebellious adolescent that can never fulfill his original expectations. By 2005, he hopes to begin replacing it with the Semantic Web—a smart network that will finally understand human languages and make computers virtually as easy to work with as other humans.
As envisioned by Berners-Lee, the new Web would understand not only the meaning of words and concepts but also the logical relationships among them. That has awesome potential. Most knowledge is built on two pillars: semantics and mathematics. In number-crunching, computers already outclass people. Machines that are equally adroit at dealing with language and reason won’t just help people uncover new insights; they could blaze new trails on their own.
Even with a fairly crude version of this future Web, mining online repositories for nuggets of knowledge would no longer force people to wade through screen after screen of extraneous data. Instead, computers would dispatch intelligent agents, or software messengers, to explore Web sites by the thousands and logically sift out just what’s relevant. That alone would provide a major boost in productivity at work and at home. But there’s far more.
Software agents could also take on many routine business chores, such as helping manufacturers find and negotiate with lowest-cost parts suppliers and handling help-desk questions. The Semantic Web would also be a bottomless trove of eureka insights. Most inventions and scientific breakthroughs, including today’s Web, spring from novel combinations of existing knowledge. The Semantic Web would make it possible to evaluate more combinations overnight than a person could juggle in a lifetime. Sure scientists and other people can post ideas on the Web today for others to read. But with machines doing the reading and translating technical terms, related ideas from millions of Web pages could be distilled and summarized. That will lift the ability to assess and integrate information to new heights. The Semantic Web, Berners-Lee predicts, will help more people become more intuitive as well as more analytical. It will foster global collaborations among people with diverse cultural perspectives, so we have a better chance of finding the right solutions to the really big issues—like the environment and climate warming.
第36题:Had he liked, Berners-Lee could have _____.
[A]created the most important innovation in the 1990s
[B]accumulated as much personal wealth as Bill Gates
[C]patented the technology of Microsoft software
[D]given his brainchild to us all
Work therefore is desirable, first and foremost, as a preventive of boredom, for the boredom that a man feels when he is doing necessary though uninteresting work is as nothing in comparison with the boredom that he feels when he has nothing to do with his days. With this advantage of work another is associated, namely that it makes holidays much more delicious when they come. Provided a man does not have to work so hard as to impair his vigor, he is likely to find far more zest in his free time than an idle man could possibly find.
The second advantage of most paid work and of some unpaid work is that it gives chances of success and opportunities for ambition. In most work success is measured by income, and while our capitalistic society continues, this is inevitable. It is only where the best work is concerned that this measure ceases to be the natural one to apply. The desire than men feel to increase their income is quite as much a desire for success as for the extra comforts that a higher income can acquire. However dull work may be, it becomes bearable if it is a means of building up a reputation, whether in the world at large or only in one's own circle.
What is the author's opinion about work?
A.Work can keep people busy as if they were poor.
B.Work is a cause of the greatest delight of life.
C.Work is very tiresome, especially when too excessive.
D.Work can at least give relief from boredom.

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 software 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.

Arthur was born as a result of the wizardry of Merlin, who arranged all adulterous liaison between Arthur's father, King Uther Pendragon, and his lover, a married duchess. Merlin agreed to do this only if the lovers allowed him to bring up the child born of the affair. When Uther Pendragon died some years later, there was confusion in the kingdom about who should inherit the throne. Merlin arranged a pageant where many knights came to try their luck at pulling a sword out of a stone. Whoever successfully extracted the blade was the rightful king. After many a brave knight had tried and failed, Merlin presented the young Arthur who, to everyone's surprise, easily pulled out the sword.
As king, Arthur established the knightly fellowship of the Round Table at his castle of Camelot, so appear all the other chivalrous knights associated with the king. The knights of the Round Table spent much of their time on the quest for the Holy Grail. The Grail is the cup used by Jesus at the Last Supper, which was allegedly brought to Britain, then somehow lost. It is notoriously hard to get hold of, as finding it requires an almost superhuman degree of moral purity. At last it was the true gentleman Sir Galahad who eventually found it and set off to return it to its rightful place in the Holy Land.
Arthur's death is a matter of some debate. According to legend, one of Arthur's less intelligent moves was his decision to marry the Lady Guinevere, who fell in love with Sir Lancelot, and their adultery led to war among the knights of the Round Table, culminating in the Battle of Camlan and Arthur's mortal woound. After the Battle of Catalan the wounded king was taken to the mysterious isle of Avalon ruled by his sister Morgan Le Faye. She, being skilled in the arts of witchcraft and healing, was apparently meant to cure him. But evidently Arthur thought he had little chance, because he gave his sword, Excalibur, to Sir Bedivere to return to the Lady of the Lake, an enigmatic character from whom Arthur had originally received the blade. Bedivere hurled the sword over the water, where a spooky hand appeared from the lake to catch it, waved it around for a while and then carried it down to the murky depths where, who knows, perhaps it still lies. As for Arthur, we can only conclude that his sister wasn't such a good doctor.
The passage is mainly about ______ .
A.a brief history of King Arthur
B.the story of the Round Table Knights
C.a legendary life of King Arthur
D.the death of King Arthur
