If you're a kid who likes to have fun and chat with friends online, here's advice on how you can stay safe.

Your parents and teachers can guide you to the best websites(网站).Some websites have age restrictions(约束), so you might want to lie about your age. It's safer to tell the truth and stay away from websites until you're older.

You can set your own passwords(密码). Passwords are your secret. It's dangerous to tell your passwords to others. So don't share your passwords with anyone.

Never tell strangers where you live or your phone number. If you're not sure whether you should share something, ask a parent. Remember that anything you put online is there forever ,even if you try to delete it. If you don't want your class to know something you shouldn't share it with anyone online, not even your best friends.

Some websites let kids make lots of friends with people they don't know. But online friends are not the same as real in - person friends. Never agree to meet an online friend in person or give out personal information. It's dangerous because some people pretend(假装)to say they are kids online but actually they are bad adults.

A. Guard your passwords.
B. Never tell pen pals your real name.
C. Visit safer websites.
D. Pick your online friends carefully.
