    Are children becoming addicted to the Internet?

    Children are becoming addicted to the Internet and for many it is one drug that can't be beaten. Not all children, but an alarming number of them are being swept up in this age of digital information.

    Websites like Myspace, Youtube, and Facebook, are becoming so popular that many kids can't help but to be addicted to them just in order to fit. Why not become part of a society where you judged by how many friends on a friend list ? What has become of the world , when instead of calling your best friend on the phone you send them a message electronically and wait around for hours to see if they get on and read it ?Often on the web there just aren't enough adults setting kids straight and too many teenagers causing trouble .

    However, it is biased to claim all kids are addicted, or even that all kids who are addicted to the web are negatively affected by it. While the web can be a large waste pool of negative influence, it is also a wealth of positive knowledge, friendly social networking, and even gateways to future employment. Perhaps it isn't so important whether or not a child is addicted to the web and more important that parents know exactly what the kids are doing there.

    Many computers have optional parent controls that allow parents to block the children from entering certain types of sites, or even individual ones. Such programs are unfortunately not used enough by today's parents, who in many cases are caught up on computers themselves. All one needs to do is google search parental controls and you will be provided with any number of companies that can help with programs for tracing child activity and, if necessary, limit time spent on the Internet .

  ____   Countrieslike France, Brazil and even Japan have their own hip-hop culture. But where did this strange speaking-singing style come from? Many centuries ago, in West Africa, traditional storytellers played musical instruments while they were telling stories. When this tradition travelled from West Africa to the USA, it developed into different musical styles. For example, blues and jazz.   ____    And in the 1970s, there were many poor areas in New York. There wasn’t any money for music lessons in schools, so kids made their own music. Teenagers Afrika and DJ Here played their records outside in the streets. Everybody joined in. MCs had rapping（说唱） competitions. Every week, there were talented new dancers, new DJs and new MCs. Hip-hop culture was born.

  ____  It was 1980. I was at a party in New York. There was a young DJ at the party. He was playing records. While he was putting a record on, a kid picked up a microphone（话筒） and begantapping. Some other kids were break-dancing to the music. It was loud and boring, and I

hated it. I preferred jazz.

  ____   Today's successful American artists like Missy and her friend Tim heard it on the radio when they were growing up.

The last time I heard hip-hop, I was in West Africa.  ____    I was going to interview a traditional storyteller when I met a young hip-hop artist, He told me there are hundreds of rap groups in Africa today. We live on a hip-hop planet.
