To help them do that, they also included tracking buoys(浮標(biāo) )on the ice that had been equipped with GPS devices.

When it es to cyberbullying (網(wǎng)絡(luò)欺凌 ), they are often motivated by anger or frustration (挫敗感 ). Sometimes they do it for entertainment or because they are bored and have too much time on their hands and too many tech toys available to them. Many do it for laughs or to get a reaction. Some do it by accident, without thinking before they do something. The powerhungry do it to make others suffer. And some think they are righting wrong and standing up for others. Because their motives differ, the solutions and responses to each type of cyberbullying incident has to differ, too. There is no “one size fits all” when cyberbullying is concerned. However, education can help considerably in preventing and dealing with the consequences of cyberbullying. If we can help kids understand how much bullying hurts, and how in many cases words can hurt, fewer may cooperate with the cyberbullies. They will think twice before forwarding a hurtful , or visiting a cyberbullying “vote for the fat girl” site, or allowing others to take videos or cell phone pictures of personal moments. And, in addition to not lending their efforts to continue the cyberbullying, we also need to teach our children not to stand silently by while others are being hurt. Martin Luther King, Jr. once said that in the end we will remember not the words of our enemies, but the silence of our friends. Kids will feel more fortable to break the silence if given an anonymous (匿名的 ) method of reporting cyberbullying websites. School administration, munity groups and even school policing staff can receive these anonymous tips and take action quickly. If our children do not allow the cyberbullies to use them to embarrass or hurt others and realize that silence, when others are being hurt, is not acceptable, cyberbullying will quickly stop. It’s a tall task, but a noble goal. And in the end, our children will be safer online and offline. We will have helped create a generation of good cybercitizens, controlling the technology instead of being controlled by it. of the following is NOT an action of cyberbullying? A. Saying cruel words to upset others. B. Standing up for others. C. Voting for the fat girl on a website. D. Forwarding a hurtful . does the underlined sentence mean? A. our friends will stick with us without saying anything. B. friends will give us silent support when we are in trouble. C. it hurts more if our friends stand by when we are suffering. D. We will fet our enemies, but remember our friends. writer anizes the passage following the pattern of ________.

D There is no doubt that schools should teach and reinforce (加強(qiáng) ) lessons consistent with what’s widely accepted to be good citizenship. They should know how not to be beastly to one another for the over 30 hours a week they’re spending at school. At my daughter’s school, there are various awards for academic and sporting achievements, but they save the best random rewards for acts of kindness, like going out of one’s way to help a teacher clean up or helpi
