     In so many ways, cyberspace (网络空间) mirrors (反映) the real world. People ask for information,

play games, and share hobby tips. Others buy and sell products. Still others look for friendship, or even

love.

     Unlike the real world, however, your knowledge about a person is limited to words on a computer

screen. Identity (身份) and appearance mean very little in cyberspace. Rather, a person's thoughts or at

least the thoughts they type are what really counts. So even the shyest person can become a chat-room

star.

     Usually, this "faceless" communication doesn't create problems. Identity doesn't really matter when

you are in a chat-room discussing politics or hobbies. In fact, this emphasis (重视) on the idea themselves makes the Internet a great place for exciting conversation. Where else can so many people come together

to chat?

     Some Internet users want more than just someone to chat with. They are looking for serious love

relationships. Is cyberspace a good place to find love? That answer depends on whom you ask. Some of

these relationships actually succeed. Others end in tears. Supporters of online relationships claim that the

Internet allows couples to know how intelligent they are first. Personal appearance doesn't get in the way.

      But critics (批评者) of online relationships argue that no one can truly know another person in

cyberspace. Why? Because the Internet gives users a lot of control over how others view them. Internet

users can carefully choose their words to fit whatever image they want to give. And they don't have to

worry about what their non-verbal communication is doing for their image. In a sense, they're not really

themselves. All of this may be fine if the relationship stays in cyberspace. But not knowing a person is a

big problem in a love relationship. With so many unknowns, it's easy to let one's imagination "fall in the

blanks". This surely leads to disappointment when couples meet in person. How someone imagines an

online friend is often quite different from the real person.

     So before looking for love in cyberspace, remember the advice of Internet pioneer Clifford Stoll,

"Life in the real world is far richer than anything you'll find on a computer screen."
