     Professor Barry Wellman of the University of Toronto in Canada has invented a term to describe the

way many North Americans interact (互动) these days. The term is "networked individualism". This

concept is not easy to understand because the words seem to have opposite meanings. How can we be

individuals (个体) and be networked at the same time? You need other people for networks.

     Here is what Professor Wellman means. Before the invention of the Internet and e-mail, our social

networks included live interactions with relatives, neighbors, and friends. Some of the interaction was

by phone, but it was still voice to voice, person to person, in real time.

     A recent research study by the Pew Internet and American Life Project showed that for a lot of people,

electronic interaction through the computer has replaced this person-to- person interaction. However, a lot

of people interviewed for the Pew study say that's a good thing. Why?

      In the past, many people were worried that the Internet isolated (孤立) us and caused us to spend too

much time in the imaginary world of the computer. But the Pew study discovered that the opposite is true.

The Internet connects us with more real people than expected - helpful people who can give advice on

careers, medical problems, raising children, and choosing a school or college. About 60 million Americans

told Pew that the Internet plays an important role in helping them make major life decisions.

     Thanks to the computer, we are able to be alone and together with other people-at the same time!
