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. Which of the following statements is TRUE about Tolerance. org______

A. It is a Web site from the Southern Poverty Law Center.
B. It is helping parents across the country create homes for those orphans.
C. The goal is to challenge those intolerant children.
D. It helps parents cultivate a sense of empathy and responsibility in their children.

第三篇 Hack The first big-name hackers include Steve Wozniak, Bill Gates and Linus Torvalds, all now highly recognizable 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 hacker. 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 bow much you train and educate your employees. If your employees disregard warnings about the hazards of opening questionable e-mail attachments, bow 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. Which of the following statements of Steve Wozniak, Bill Gates and Linus Torvalds is TRUE

A. They are all good examples of today’s computer users.
B. They are driven by greed, power, revenge, or some other malicious intent.
C. Their goal is to push programs beyond what they are designed to do.
D. They are all dead.
