How to be safe on the Internet
At present, most of us use the Internet to get useful knowledge and information, and to relax in our free time. But some of us are not using it in a good way, such as being crazy about playing games. Here are some rules to make us safe and have fun on the Internet. First, we should make rules for Internet use with our parents. Never give out our real personal information to strangers. We aren’t allowed to meet anyone we meet on line alone. It’s impolite of you to say bad words about others. Besides, suitable chatting rooms are good for you, or you should leave them at once. I hope everyone uses the Internet in a right and polite way. If so, the Internet will be safe and useful for us.
