The first big-name hackers include Steve Wozniak, Bill Gates and Linus Torvalds, all now highly recognisable names behind many of the computer technologies used today. These early hackers had a love of technology and a compelling need to know how it all worked, and their goal was to push programs beyond what they were designed to do. Back then, the word "hacker" didn’t have the negative connotation it has today. The original hacker ethic, rooted out of simple curiosity and a need to be challenged, appears to be dead.The objectives of early hackers are a far cry from the goals of today’s hackers. The motivation of the new breed of hackers appears not to be curiosity, or a hunger for knowledge, as it used to be. Instead, most of today’s hackers are driven by greed, power, revenge, or some other malicious intent, treating hacking as a game or sport, employing the tools that are readily available via the Internet.The rate of security attacks is actually outpacing the growth of the Internet. This means that something besides the growth of the Internet is driving the rise in security attacks. Here are some realities you should know about: Operating systems and applications will never be secure. New vulnerabilities will be introduced into your environment every day. And even if you ever do get one operating system secure, there will be new operating systems with new vulnerabilities--phones, wireless devices, and network appliances. Employees will never keep up with security polices and awareness. It doesn’t matter how much you train and educate your employees. If your employees disregard warnings about the hazards of opening questionable email attachments, how are you going to educate them about properly configuring firewalls and intrusion detection systems for their PCs Managers have more responsibility than ever. And on top of the realities listed above, security managers are being asked to support increasing degrees of network availability and access.There are some good security measures you can take: Employ a layer 7, full-inspection firewall. Automatically update your anti-virus at the gateway, server and client. Keep all of your systems and applications updated. Hackers commonly break into a Web site through known security holes, so make sure your servers and applications are patched and up to date. Turn off unnecessary network services. Eliminate all unneeded programs. Scan network for common backdoor services--Use intrusion detection systems, vulnerability scans, anti-virus protection. 53 Which of the following is NOT true of security attacks().

A. Employees will keep up with security polices and awareness if they are highly-trained.
B. The rate of security attacks appears faster than the growth of the Internet.
C. One’s computer system will never be secure.
D. Vulnerabilities can go through phones, wireless devices, and network appliances.

As Eleanor Roosevelt once said, "Universal human rights begin in small places, close to home. " And Tolerance. org, a Web site from the Southern Poverty Law Center, is helping parents across the country create homes in which tolerance and understanding are guiding themes. "The goal of nurturing open-minded, empathetic children is a challenging one," says Jennifer Holladay, director of Tolerance. org. "To cultivate tolerance, parents have to instill in children a sense of empathy, respect and responsibility--to oneself and to others--as well as the recognition that every person on earth is a treasure. " Holladay offers several ways parents can promote tolerance:Talk about tolerance. Tolerance education is an ongoing process; it cannot be captured in a single moment. Establish a high comfort level for open dialogue about social issues. Let children know that no subject is taboo. Identify intolerance when children are exposed to it. Point out stereotypes and cultural misinformation depicted in movies, TV shows, computer games and other media. Challenge bias when it comes from friends and family members. Do not let the moment pass. Begin with a qualified statement: "Andrew just called people of XYZ faith ’lunatics. ’ What’ do you think about that, Zoe" Let children do most of the talking. Challenge intolerance when it comes from your children. When a child says or does something that reflects biases or embraces stereotypes, confront the child: "What makes that joke funny, Jerome" Guide the conversation toward internalization of empathy and respect--"Mimi uses a walker, honey. How do you think she would feel about that joke" or "How did you feel when Robbie made fun of your glasses last week" Support your children when they are the victims of intolerance. Respect children’s troubles by acknowledging when they become targets of bias. Don’t minimize the experience. Provide emotional support and then brainstorm constructive responses. For example, develop a set of comebacks to use when children are the victims of name-calling. Create opportunities for children to interact with people who are different from them. Look critically at how a child defines "normal". Expand the definition. Visit playgrounds where a variety of children are present--people of different races, socioeconomic backgrounds, family structures, etc. Encourage a child to spend time with elders--grandparents, for example. Encourage children to call upon community resources. A child who is concerned about world hunger can volunteer at a local soup kitchen or homeless shelter. The earlier children interact with the community, the better. This will help convey the lesson that we are not islands unto ourselves. Model the behavior you would like to see. As a parent and as your child’s primary role model, be consistent in how you treat others. Remember, you may say, "Do as I say, not as I do," but actions really do speak louder than words. According to the passage, children are encouraged to join in many activities other than ().

A. live in homeless shelter
B. spend time with elders
C. volunteer at a local soup kitchen
D. visit playgrounds where a variety of children are present

There are two factors which determine an individual’s intelligence. The first is the sort of brain he is born with. Human brains differ considerably, some being more capable than others. But no matter how good a brain he has to begin with, an individual will have a low order of intelligence unless he has opportunities to learn. So the second factor is what happens to the individual--the sort of environment in which he is reared. If an individual is handicapped environmentally, it is likely that his brain will fail to develop and he will never attain the level of intelligence of which he is capable.The importance of environment in determining an individual’s intelligence can be demonstrated by the case history of the identical twins, Peter and Mark. Being identical, the twins had identical brains at birth, and their growth processes were the same. When the twins were three months old, their parents died, and they were placed in separate foster homes. Peter was reared by parents of low intelligence in an isolated community with poor educational opportunities. Mark was reared in the home of well-to-do parents who had been to college. He was read to as a child, sent to good schools, and given every opportunity to be stimulated intellectually. This environmental difference continued until the twins were in their late teens, when they were given tests to measure their intelligence. Mark’s I.Q. was 125, twenty-five points higher than the average and fully forty points higher than his identical brother. Given equal opportunities, the twins, having identical brains, would have tested at roughly the same level. The best statement of the main idea of the passage is that ().

A. human brains differ considerably
B. the brain a person is born with is important in determining his intelligence
C. environment is crucial in determining a person’s intelligence
D. persons having identical brains will have roughly the same intelligence

Standard English is the variety of English which is usually used in print and which is normally taught in schools and to non-native speakers learning the language. It is also the variety which is normally (21) by educated people and used in news broadcasts and other (22) situations. The difference between standard and nonstandard, it should be noted, has (23) in principle to do with differences between formal and colloquial (24) ; standard English has colloquial as well as formal variants.(25) , the standard variety of English is based on the London (26) of English that developed after the Norman Conquest resulted in the removal of the Court from Winchester to London. This dialect became the one (27) by the educated, and it was developed and promoted (28) a model, or norm, for wider and wider segments of society. It was also the (29) that was carried overseas, but not one unaffected by such export. Today, (30) English is arranged to the extent that the grammar and vocabulary of English are (31) the same everywhere in the world where English is used; (32) among local standards is realIy quite minor, (33) the Singapore, South Africa, and Irish varieties are really very (34) different from one another so far as grammar and vocabulary are (35) . Indeed, Standard English is so powerful that it exerts a tremendous (36) on all local varieties, to the extent that many of long-established dialects of England have (37) much of their vigor and there is considerable pressure on them to be (38) . This latter situation is not unique (39) English: it is also true in other countries where processes of standardization are (40) . But it sometimes creates problems for speakers who try to strike some kind of compromise between local norms and national, even supranational (跨国的) ones. 22().

A. same
B. similar
C. equal
D. identical
