12．How to protect children Web fans from unsuitable material on-line while encouraging them to use the Internet has long been discussed in the U．S．
For some parents，the Internet can seem like a jungle，filled with danger for their children．But jungles contain wonders as well as hazards （危險(xiǎn)） and with good guides，some education，and a few precautions （預(yù)防措施），the wilds of the Internet can be safely navigated （航行）．"Kids have to be on-line．If we tell our kids they can't have access （機(jī)會(huì)） to the Internet，we're cutting them off from their future，"said an expert．
Most kids have started to use search engines．Many of them are great for finding tons of interesting Internet sites，and they can also locate places where you might not want your kids to go．There are search engines designed just for kids．A certain software contains only sites that have been selected as safe．The most popular way to limit access would be to use what is known as a"content screener （過濾器）"．But this can't be wholly reliable （可靠），and the best thing parents can do is to talk to their kids and let them know what is OK or not OK to see or do on the Internet．Another way is that mum or dad is nearby when the child is surfing （瀏覽） the Internet．
A few other tips：
-Don't put the PC in a child's room but keep it in an area where mum or dad can keep an eye on things．That also makes the Internet more of a family activity．
-Ask your child what he or she has been doing and about any friends they make on-line．
-Tell your child not to give on-line strangers personal information，especially like address and phone number．
-And tell your children never to talk to anyone they meet on-line over the phone，send them anything，accept anything from them or agree to meet with them unless you go along．
