12、 relates to the possibility that artificial intelligence(AI) may become extremely good at achieving something other than what we really want. In 1960 a well-known mathematician Norbert Wiener, who founded the field of cybernetics（控制论）, put it this way: “If we use, to achieve our purposes, a mechanic
13、al agency with whose operation we cannot effectively interfere(干预), we had better be quite sure that the purpose which we really desire.”A machine with a specific purpose has another quality, one that we usually associate with living things: a wish to preserve its own existence. For the machine, thi
14、s quality is not in-born, nor is it something introduced by humans; it is a logical consequence of the simple fact that the machine cannot achieve its original purpose if it is dead. So if we send out a robot with the single instruction of fetching coffee, it will have a strong desire to secure succ
15、ess by disabling its own off switch or even killing anyone who might interfere with its task. If we are not careful, then, we could face a kind of global chess match against very determined, super intelligent machines whose objectives conflict with our own, with the real world as the chessboard. The
16、 possibility of entering into and losing such a match should concentrating the minds of computer scientists. Some researchers argue that we can seal the machines inside a kind of firewall, using them to answer difficult questions but never allowing them to affect the real world. Unfortunately, that
17、plan seems unlikely to work: we have yet to invent a firewall that is secure against ordinary humans, let alone super intelligent machines.Solving the safety problem well enough to move forward in AI seems to be possible but not easy. There are probably decades in which to plan for the arrival of su
18、per intelligent machines. But the problem should not be dismissed out of hand, as it has been by some AI researchers. Some argue that humans and machines can coexist as long as they work in teamsyet that is not possible unless machines share the goals of humans. Others say we can just “switch them o
19、ff” as if super intelligent machines are too stupid to think of that possibility. Still others think that super intelligent AI will never happen. On September 11, 1933, famous physicist Ernest Rutherford stated, with confidence, “Anyone who expects a source of power in the transformation of these at
20、oms is talking moonshine.” However, on September 12, 1933, physicist Leo Szilard invented the neutron-induced(中子诱导) nuclear chain reaction.1.Paragraph 1 mainly tells us that artificial intelligence may .A. run out of human controlB. satisfy humans real desiresC. command armies of killer robotsD. wor

It will be solved but with difficulty.BAfter years of heated debate, gray wolves were reintroduced to Yellowstone National Park. Fourteen wolves were caught in Canada and transported to the park. By la
24、st year, the Yellowstone wolf population had grown to more than 14 wolves.Gray wolves once were seen here and there in the Yellowstone area and much of the continental United States, but they were gradually displaced by human development. By the 1920s, wolves had practically disappeared from the Yel
25、lowstone area. They went farther north into the deep forests of Canada, where there were fewer humans around.The disappearance of the wolves had many unexpected results. Deer and elk populations major food sources (来源) for the wolf grew rapidly. These animals consumed large amounts of vegetation (植被
26、), which reduced plant diversity in the park. In the absence of wolves, coyote populations also grew quickly. The coyotes killed a large percentage of the park s red foxes, and completely drove away the park s beavers.As early as 1966, biologists asked the government to consider reintroducing wolves
27、 to Yellowstone Park. They hoped that wolves would be able to control the elk and coyote problems. Many farmers opposed the plan because they feared that wolves would kill their farm animals or pets. The government spent nearly 7 years coming up with a plan to reintroduce the wolvers. The U.S. Fish
28、and Wildlife Service carefully monitors and manages the wolf packs in Yellowstone. Today, the debate continues over how well the gray wolf is fitting in at Yellowstone. Elk, deer, and coyote populations are down, while beavers and red fores have made a comeback. The Yellowstone wolf project has been
29、 a valuable experiment to help biologists decide whether to reintroduce wolves to other parts of the country as well.5.What is the text mainly about?A. Wildlife research in the United States.B. Plant diversity in the Yellowstone area.C. The conflict between farmers and gray wolves.D. The reintroduct
