Internet has become part of young people’s life. You can do lots of things on line such as chatting, sending messages and emails, getting useful knowledge and information, buying things without going to the shops, visiting cool websites, and so on. But it’s also easy to be cheated online. Here’s a story about a girl named Mary.
Mary is an 18-year-old girl who lives in New York. The people in Mary’s family are so busy that they hardly have time to be with her. In fact, Mary is quite lonely. So she spends a lot of time on QQ.
Last year Mary made a very special friend on QQ. His name was David and he lived in San Francisco. David was full of stories and jokes. He and Mary had a common interest in rock music and modern dance. So it always took them hours to talk happily on QQ and sometimes they even forgot the time. David sent Mary a picture of “himself”: he was a tall, good-looking young man with a big, happy smile. As time went by, they became good friends and often sent cards and small things to each other.
Before David’s birthday, Mary wanted to give him a surprise. She flew to San Francisco. But when Mary knocked on David’s door, she found that the special friend was a twelve-year-old boy named Jim!
So when you make friends on the Internet, please be careful. Here are some rules to make sure you are safe and have fun on the Internet.
uDon’t give your password to anyone else, and never let out the following information: your real name, home address, age, school, phone number or other personal information.
uNever agree to meet someone you met on the Internet without your parents’ permission. Never meet anyone you met online alone.
uAlways remember that people online may not be who they say they are. Treat everyone online as if they were strangers.
uRemember — not everything you read on the Internet is true.
