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!
