Net Addiction

Net Addiction

A lot of people enjoy surfing the Net.They look for interesting Web sites and chat with

people all over the world. However, some people spend such (so) many hours online

that they are internet addicts. Although an average person spends about eight to twelve

hours per week, but an addict spends eight to twelve hours per day online. Because

addicts spend so much time interacting with the computer so (that) their lives are

negatively affected. They become social recluses, because they stop going out and

talking to people face-to face. They avoid real- life social situations , preferring instead

to be in a dimly lit room with only the glowing screen to light up their lives.

Internet addiction affects not only the addicts themselves but also the people around

them. For example, John's marriage to Martha broke up until (because ) he insisted on

spending so many hours on the Net. As soon as (wheneve ) he arrived home from work,

he was at his computer. While (After) he finished dinner, he would disappear into his

computer room again. He paid so little attention to her, that she finally divorced him.

Since college students are especially technologically skilled, they can easily become

nonstop Net-surfers. Most colleges provide computers around campus, so that students

can use them at any time day or night. As a result, students can spend too much time

surfing the Net instead of "surfing" their textbooks. Last semester, nine freshmen at

Berkshire College flunked out although (because) they became internet addicts. In

short, even though the Internet is an excellent source of information and entertainment,

but we must not let it take over our lives.
