     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 lake 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 online alone.

 strangers.

  right away.
