23、dget constraints, general user and corporate management attitudes, lack of knowledge of the copyright laws, and now Internet access. Most organizations have not managed their software very effectively. Determining the extent of the problem is a time-consuming process.The industrys response has been
24、to form trade associations to educate the public about the copyright law and to aggressively pursue pirates. Some of the largest PC companies have set up their own in-house programs to combat the problem.Corporate exposure is increasing due to the need to manage more machines, software and on-line a
25、nd Internet access. Civil and criminal penalties for copyright infringement have stiffened. As a result, trade association resources have increased significantly as well as calls to hotlines from unhappy employees due to corporate downsizing.When infringing software is reported, the company is at ri
26、sk of embarrassing litigation for copyright infringement. The company will most probably lose as the copyright holder usually has a “smoking gun“ based on reports from former employees or other whistle blowers. There is also the simple fact that no matter how hard the IS staff try, there are and alw
27、ays will be copies of software programs that cannot be validated by purchasing records. They come in from home, are created by otherwise conscientious employees trying to get their jobs done or just unauthorized copies by purchasing records. They come in unauthorized copies created by cost conscious
28、 managers and employees. Internet access only increases these problems as software is downloaded from sites worldwide.A software management program will reduce the risks from using counterfeit or copied software and help avoid damage from viruses and corrupt programs. By conducting an audit before i
29、nfringement is reported the corporation will reduce its exposure.It is easy to inventory software programs on any particular machine. However, matching the software to the licensing documents is no easy task. Interpreting the variety of software licenses takes familiarity with industry business and
30、licensing practices. Networks make the task much more complex. Internet access compounds the problem.Employers should set guidelines for when and how to download software and data from on-line services and the Internet. Most software vendors maintain on-line support and provide the ability to downlo
31、ad bug fixes and program updates. However, one bad virus can wreak havoc throughout a companys networks and shut down the whole system. Firewall technology that controls access to and from outside systems can help.Information systems staff should work with management to develop policies that reduce
32、risk but reflect the level of openness that suits a particular companys corporate culture.（分数：5.00）(1).This passage aims at providing advice to _.（分数：1.00）A.software companiesB.business companiesC.lawmakersD.corporate employees(2).What is the role of Internet in software piracy?（分数：1.00）A.It is a we
33、apon against software piracy.B.It is an accessory to software piracy.C.It is the most important cause of software piracy.D.It has nothing to do with software piracy.(3).“Smoking gun“ in the fourth paragraph means _.（分数：1.00）A.reports from former employeesB.irrefutable evidenceC.debtorD.trade associa
34、tions(4).The author believes that _.（分数：1.00）A.an audit before infringement will solve the problem of corporate exposure to software piracyB.employees should be encouraged to bring software from homeC.virus can be downloaded from the InternetD.software licenses are all similar(5).The author advises
35、information systems staff to work with management in making policies because _.（分数：1.00）A.they are in charge of making policiesB.they are responsible for avoidance of software piracyC.they are familiar with the companys corporate cultureD.they are frequently the actual wrong-doersBPassage 2/BThe mor
36、e time scientists spend designing computers, the more they marvel at the human brain. Tasks that stump the most advanced supercomputer-recognizing a face, reading a handwritten note-are childs play for the 3-lb. organ. Most important, unlike any conventional computer, the brain can learn from its mi
37、stakes. Researchers have tried for years to program computers to imitate the brains abilities, but without success. Now a growing number of designers believe they have the answer: if a computer is to function more like a person and less like an over-grown calculator, it must be built more like a bra
38、in, which distributes information across a vast interconnected web of nerve cells, or neurons.Conventional computers function by following a chainlike sequence of detailed instructions. Although very fast, their processors can perform only one task at a time. This approach works best in solving prob
39、lems that can be broken down into simpler logical pieces. The processors in a neural-network computer, by contrast, form a grid much like the nerve cells in the brain. Since these artificial neurons are interconnected, they can share information and perform tasks at the same time. This two-dimension
40、al approach works best at recognizing patterns.Instead of programming a neural-network computer to make decisions, its maker trains it to recognize the patterns in any solution to a problem by repeatedly feeding examples to the machine. This process is like a process that prepares all possible moves
41、 in a chess game and try to find a best approach to it. If the examples are not sufficient or complete, the computer will be in for trouble, after all, it can not respond to something it can not recognize as a pattern in its memory.Neural networks come in all shapes and size. The new networks will m
42、ake things which were simply impossible completely feasible in the near future. What the users need to do is to wait and see. Developers are experimenting with new equipment and hopefully they will succeed. Until now most existed as software simulations because redesigning computer chips took a lot
43、of time and money. By experimenting with different approaches through software rather than hardware, scientists have been able to avoid costly mistakes.（分数：5.00）(1).What does the word “stump“ in paragraph 1, line 2, mean?（分数：1.00）A.Catch.B.Baffle.C.Please.D.Force.(2).It can be inferred from the firs
44、t paragraph that the most advanced supercomputer _.（分数：1.00）A.can recognize a face and read a handwritten noteB.can learn from the pastC.cannot fail to imitate the human brains abilitiesD.cannot distribute information across all interconnected web of nerve cells(3).The main feature of a neural-netwo
45、rk computer is that _.（分数：1.00）A.its processors net is an interconnected web of neuronsB.it is programmed to make decisionsC.its networks are of all shapes and sizesD.its neurons are artificial(4).According to the passage, the expression “this two-dimensional approach“ in the last sentence of the se
46、cond paragraph refers to _.（分数：1.00）A.the conventional computer and the neural computerB.the lockstep approach and the artificial approachC.sharing information and performing tasksD.making decisions and recognizing patterns(5).Scientists use software rather than hardware in their experiment because
47、_.（分数：1.00）A.it can adjoin redesigning computer chipsB.it can avoid making mistakesC.it can save a lot of time and moneyD.it can mimic the human brains abilitiesBPassage 3/BA new era is upon us. Call it what you will: the service economy, the information age, the knowledge society. It all translates
48、 to a fundamental change in the way we work. Already were partly there. The percentage of people who earn their living by making things has fallen dramatically in the Western World. Today the majority of jobs in America, Europe and Japan (two thirds or more in many of these countries) are in the service industry, and the number is on th
