Police in the popular resort city Virginia Beach recently began operating video surveillance cameras with controversial face recognition technology. Virginia Beach and Tampa in Florida two cities in the United States acquired the technology, which cost them $ 197, 000.” “Before we switched it on, we went through an extensive public education process with hearings and the involvement of citizen groups and minority groups, who helped write the policies we are using, " said deputy police chief Greg Mullen. A citizens' auditing committee has the right to perform. unannounced spot checks on police headquarters to make sure the technology is not being misused.Three of the city's 13 cameras are linked full time to the face recognition system, though the others can be activited as needed. The database of wanted people is updated every day. So far, the system has failed to produce a single arrest, though it has generated a few false alarms. It works by analyzing faces based on a series of measurements, such as the distance from the tip of the nose to the chin or the space between the eyes. Critics say it is highly inaccurate and can be easily fooled. Mullen, who sees the system eventually being linked to the databases of other city, state and federal law enforcement agencies to track criticals and suspected terrorists, said, "The system doesn't look at skin color or your hair or your gender. It takes human prejudices out of the equation. ""This technology has little or no effect on the crime rate but it does have an effect on people's behavior. People feel cowed, " said Bruce Steinhardt, who directs the technology. Despite the fact that tests have shown faces recognition only works in around 30% cases, the ACLU is alarmed that the technology may soon spread to airports. The organization also fears it could potentially be used to monitor individual's political activities to harass law-abiding citizens." This kind of surveillance should be subject to the same procedures as wiretaps. Law enforcement agencies should justify why they need it and it should be tightly limited, otherwise it will soon become a tool of social control, " said Mihir Kshisagar of the Electronic Information Privacy Center. Nor does such criticism come exclusively from the political left. Lawyer John Whitehead, founder of the conservative Rutherford Institute, wrote in an editorial that the technology threatened the right of each U. S. citizen to participate in society. "After all, that is exactly what constant surveillance is—the ultimate implied threat of coercion, " he wrote.What does Mullen's statement in Paragraph 1 indicate?A．Police is confident in using the technology.B．Police has made preparation for the use of the technology.C．Citizens have rights over managing the technology.D．Police has gone through public education process.

●Border Gateway Protocol(BGP) is inter-autonomous system (71) protocol. BGP is based on a routing method called path vector routing. Distance vector routing is not a good candidate for inter-autonomous system routing because there are occasions on which the route with the smallest (72) count is not the preferred route. For example, we may not want a packet through an not secure even though it is the shortest route. Also, distance vector routing is unstable due to the fact that the routers announce only the number of hop counts to the destination without actually defining the path that leads to that (73) ．A router that recevives a distance vector advertisement packet may be fooled if the shortest path is actually calculated through the receiving router itself. Link (74) routing is also not a good candidate for inter-autonomous system routing because an Internet is usually too big for this routing method. To use link state routing for the whole internet would require each routex to have a huge link state database. It would also take a long time for each router to calculate its rousting (75) using the Dijkstra algorism.（71）A. routingB. switchingC. transmittingD. receiving(72)A. pathB. hop `C. routeD. packet(73）A. connectionB. windowC. sourceD. destination(74)A. statusB. searchC. stateD. research(75）A. tableB. stateC. metricD. cost

Passage 2 A great deal of attention is being paid today to the socalled digital divide — the division of the world into the info(information) rich and the info poor. And that divide does exist today. My wife and I lectured about this looming danger twenty years ago. What was less visible then, however, were the new, positive forces that work against the digital divide. There are reasons to be optimistic.There are technological reasons to hope the digital divide will narrow. As the Internet becomes more and more commercialized, it is in the interest of business to universalize access — after all, the more people online, the more potential customers there are. More and more governments, afraid their countries will be left behind, want to spread Internet access. Within the next decade or two, one to two billion people on the planet will be netted together. As a result, I now believe the digital divide will narrow rather than widen in the years ahead. And that is very good news because the Internet may well be the most powerful tool for combating world poverty that we've ever had.Of course, the ue of the Internet isn't the only way to defeat poverty. And the Internet is not the only tool we have. But it has enormous potential.To take advantage of this tool, some impoverished countries will have to getover their outdated anticolonial prejudices with respect to foreign investment. Countries that still think foreign investment is an invasion of their sovereignty might well study the history of infrastructure (the basic structural foundations of a society) in the United States. When the United States built its industrials infrastructure, it didn't have the capital to do so. And that is why America's Second Wave infrastructure — including roads, barbors, highways, prots and so on — were built with foreign investment. The English, the Germans, the Dutch and the French were investing in Britain's former colony. They financed them. Immigrant Americans built them. Guess who owns them now? The Americans. I believe the same thing would be true in places like Brazil or anywhere else for that matter. The more foreign capital you have helping you build your Third Wave infrastructure, which today is an electronic infrastructure, the better off you're going to be. That doesn't mean lying down and becoming fooled, or letting foreign corporations run uncontrolled. But it does means recognizing how important they can be in building the energy and telecom infrastructures needed to take full advantage of the Internet.第55题：Digital divide is something _______ .A getting worse because of the InternetB the rich countries are responsible forC the world must guard againstD considered positive today
