“I check my e-mail almost forty times a day.”

“I seldom spend less than three hours each time on the net.”

Do you know any people like these? They are part of a new addiction(癮) called Internet addiction.According to experts,Internet addicts(迷)spend at least thirty to forty hours online every week.They lose control of the time they spend on the Internet.

A study shows that about six to ten percent of Internet users become addicted.The teenager spend more time on the Internet than with friends and family. That’s why some experts worry most about young people.

★You can’t wait to get online again.

★You’ve decided to spend a short time online,but then you spend several hours.

★You do not go to important family events or you do not do school projects because you like to spend hours on the Internet.
