第1题
A lot of kids are getting online these days—sharing data, talking about social issues, meeting adults as well as kids, and learning about other cultures. There seems to be everything on the network. Just like any other form. of media, the quality of this massive collection of information is
unequal, and there is good information as well as rubbish. Networks hold great promise: however,
it's also home to people who mean to hurt others or use their technical knowledge to steal from them . Although many Web pages can teach kids useful things, there are some other sites waiting to temp young people who are immature and easily affected.
By now, you may shake your head, but wait, let's try to put the problem into perspective Generally.it's safe for kids to use the Internet. The number of sites considered harmful is between 1% and 3%, which shows about 4.5 million other sites are interesting and educational. Besides, to stop children from using these services just because crimes are being committed online would be like telling them not to attend college because students may have accidents on campus.
What can parents do to protect their children from those harmful sites？ The simplest solution is the use of programs which block offensive sites. Such programs are set to screen out certain words likely to appear on”unhealthy”sites. But many sites inappropriate to young people are clever at using words with double meanings that may appear harmless. What's more, not only do the programs fail to do the job satisfactorily, they also take away the decisive role of parents in children's education. A child who downloads bad information or pictures can only be corrected by positive family influence. No filtering program is necessary for a child who has learned to say“no”to sites he knows are inappropriate for him.
Today, when children are exposed to technology at a young age, parents often find themselveslagging behindin computer skills. Surprisingly, this may be the key to your involvement. What is better way to learn about the Internet than to do so alongside your children？
They'll most likely pick it up more quickly than you do, of course, but you'll have the chance to see, and take pride in, your child at work. You may search for information that interests your child together with him and get to know the”friends”he has online, just as you would get to know his other friends.
Thoughtful parents would combine supervision with communication, which is the best way to take advantage of the Internet as a resource while protecting their children. Follow their examples and have fun with kids on the Net!
