　　While the Internet opens a world of possibilities for children, they can be exposed to dangers as well. So teaching your kids the Internet safety is a must if you want to keep them safe while they can enjoy the benefits brought by the Internet. Below are some tips that you can follow to protect your children in the modern information age.

　　Start by taking some time to sit down and explain the potential dangers of surfing the Internet to your children. You can explain how important it is for them to know that there are some people on the Internet who will trick them by pretending to be someone they are not.

　　Make sure that your children understand that they should never give out personal information under no circumstances. Personal information includes address, phone number or parents' work information. Tell your children not to talk about things like going to ball games or other activities to strangers as these can help strangers locate where they are. Your children should never post a photo of themselves, family members or friends on the Internet without your approval.

　　Tell them never to open an e-mail from someone they don't know. You should also explain to your children that they should never respond to any messages that are sent in anger. Above all, tell them never to meet any strangers that they met online without your supervision(监督).

　　Keep the computer in a neutral(中立的)area of the home such as the living room. This allows you to see what is going on and know for sure how long your children stay online. Use any means available to make sure that your children cannot visit the websites that you feel are inappropriate.
