Many children use the Internet to get useful knowledge and information, and to relax in their free time. But some of them are not using in 
a good way. Here are some rules to make sure you are safe and have fun on the Internet.
● Make rules for Internet use with your parents. For example, when you can go online, for how long and what activities you can go online.
● Don’t give your password (密码) to anyone else, and never leak out the following information---your real name, home address, age, school, phone number or other personal information.
● Check with your parents before giving out a credit (信用) card number.
● Never send a photo of yourself to someone in e-mail unless your parents say it’s OK.
● Check with your parents before going into a chat room. Different chat rooms have different rules and attract different kinds of people. You and your parents must make sure it’s a right place for you.
● Never agree to meet someone you met on the Internet without your parent’s permission (允许). Never meet anyone you met on line alone.
● Always remember that people online may not be who they say they are. Treat everyone online as strangers.
● If something you see or read online makes you uncomfortable, leave the site. Tell a parent or teacher right away.
