Read the passage carefully, then choose the correct answers. The latest addiction to trap thousands of people is the Internet, which has been blamed for broken relationships, job losses, financial ruin, and even suicide. Psychologists now recognize Internet Addiction Syndrome (IAS) as a new illness that could cause serious problems and ruin many lives. IAS is similar to other problems like gambling, smoking and drinking: addicts have dreams about the Internet; they need to use it as the first thing in the morning; they lie to their parents and partners about how much time they spent online; they wish they could cut down, but are unable to do so. A recent study found that many users spend up to 40 hours a week on the Internet. Some of the addicts are teenagers who are already hooked on computer games and who find it very difficult to resist the games on the Internet. What is the best title of the passage? A: The advantage of the Internet B: A guide to the Internet C: Hooked on the Net D: Impact of Internet on teens
