Ten years ago, all you needed to protect yourself was a safe, a fence and security officers, said Chris Swecker, who is in charge of the FBI39。s Charlotte office. Now any business with a modem is subject to attack. FBE agents investigating puter hacking that disrupted popular Web sites including , CNN and Yahoo! this year identified several North Carolina victims. The investigation has also identified puter systems in North Carolina used by hackers to mit such attacks. Prosecutions of hackers have been hampered by the reluctance of businesses to report security intrusions for fear of bad publicity and lost business. Meanwhile, too many corporations have made it too easy for criminals by sacrificing security for speed and accessibility. Jack Wiles, who will lead the local InfraGard chapter39。s board, said a recent report estimated 97 percent of all cybercrime goes undetected. Wiles, a puter security expert, has a firewall on his personal puter to prevent hackers from getting into his files. I get at least one report a day that somebody was trying to get into my puter, he said. The Net is a wonderful place, but it39。s also a dangerous one. 21. From the first paragraph, we know [A] InfraGard is a protective measure aga/nst cybercrime. [BI InfraGard is a measure of cooperation and collaboration. [C] there will be 50 InfraGard chapters in all states. [DJ private business and the government are now mitting cybererime. 22. Each local chapter of InfraGard will be run by the following EXCEPT [Al academic munities. [B] public agencies. [C] FBI. [D] private industry. 23. By saying too many corporations have made it too easy for criminals by sacrificing security for speed and accessibility the author means [A] too many corporations take no notice of the security problem of puters. [B] criminals are sacrificing security for speed and accessibility. [C] it39。s very easy to sacrifice security for speed and accessibility. [D] many panies suffer from puter hacking because they value speed and accessibility more than security. 24. All the following are reasons for the rise in cybercrime EXCEPT [A] victims won39。t report intrusions by hackers. [B] vi victims have no fkewalls. [C] the use of modem is increasing. [D] panies don39。t pay enough attention to Security. 25. It can be concluded from the passage that [A] not all hacking attempts are worthy of investigation. [B] information of the victims is inaccessible. [C] InfraGard chapters will be in effect by the end of September. [D] was once disrupted by hacking. Text 2 The annual Phi Delta Kappa/Gallup poll of attitudes towards public education releasedthis week found that a majorty of Americans feel t is important to put a qualified,petent teacher in every classroom. Bob Chase, president of the National EducationAssociation (NEA), the main teachers39。 union, wasted no time in pointing out that this willrequire raising teachers39。 salaries so that more qualified candidates will enter the profession andstay there. A study by two economists suggests that the quality of America39。s teachers has more to dowith how they are paid rather than how much. The pay of American publicschool teachers isnot based on any measure of performance。 instead, it is determined by a rigid formula based onexperience and years of schooling, factors massively unimportant in deciding how wellstudents do. The uniform pay scale invites what economists call adverse selection. Since the mosttalented teachers are also likely to be good at other professions, they have a strong incentive toleave education for jobs in which pay is more closely linked to productivity. For dullards, theincentives are just the opposite. The data are striking: when test scores are used as a proxy for ability, the brightestindividuals shun the teaching profession at every juncture. Clever students are the least likelyto choose education as a major at university. Among students who do major in education, those with higher test scores are less likely to bee teachers. And among individuals who enterteaching, those with the highest test scores are the most likely to leave the profession early. The study takes into consideration the effects of a nationwide 20% real increase in teachersalaries during the 1980s. It concludes that it had no appreciable effect on overall teacherquality, in large part because schools do a poor job of. recruiting andselecting the best , even if higher salaries lure more qualified candida
