     As the Internet's influence grows, the potential for danger also escalates (逐步上升). One of these

dangers is from cyber-bullying. Cyber-bullying (网络欺凌) is repeatedly hurting someone else through

the use of technology. It consists of sending or posting cruel messages, photos, or videos on the Internet

or other electronic media with the intent of damaging the reputation of the target. Imagine being a

13-year-old girl discovering a cell phone picture of her changing clothes for gym class has been sent to

all her classmates. Or imagine being an 11-year-old boy who is scared to go to school because an

unknown bully sent him an instant message saying that he is so fat that he should kill himself. Cases such

as these are happening every day, leading kids to be depressed and unable to concentrate.

     Worse yet, parents are oblivious (忽视的) to what is happening. Only 15 percent of parents even

know what cyber-bullying is. And anyone who thinks that their child is not a victim or a bully is probably

wrong. 90 percent of middle school students have had their feelings hurt online and 75 percent have

admitted to visiting a website attacking another student.

     Unlike traditional schoolyard bullying, where a bully has a name and a face, cyber-bullying gets much

of its power from anonymity (匿名). A cyber bully might design a website posting cruel remarks about a

classmate and never tell anyone that he or she was the creator. The cyber-bullying also gets its power

from the scope (范围) of its audience. Within seconds, a cyber bully can send an e-mail to everyone he

or she knows, inviting them to take part in an online poll (民意测验) of who is the ugliest kid in their

class. Victims can be picked on day and night from any place.

     The good news is that you can help stop cyber-bullying. By making parents and educators aware of

what is going on and encouraging them to take quick and strong action when cyber-bullying cases happen, you can help make technology constructive, not destructive, for young people.
