     New economy online

     People are talking about the "new economy". It's very different from the "old economy".

     In the old economy, people travel to walk. They buy things in stores. They use the post office, the fax and

the telephone to send information. They see people face-to-face at their jobs or in stores. People get information from newspapers, radio, television, books and libraries.

     In the new economy, people do business through the "net", which is a connection of millions of computers

everywhere in the world. In the new economy, workers often work at home. They can get information online.

They can communicate with employers and co-workers by e-mail. Businesses have"virtual (虚拟的) stores".

They are websites on which customers can see the products. Business can sell to customers anywhere in the

world.

    In the new economy, people live a fast paced, convenient and colorful life. The whole world develops more

quickly than before. But the new economy is double-edge sword (双刃剑). Its disadvantage is also obvious.

For example, the Internet has led to a huge increase in credit care (信用卡) cheating. Some illegal websites

offer some cheap or banned(禁止的) goods or services. Online shoppers who enter their credit card

information may never receive the goods they want to buy and their card information could even be for sale in

an illegal website. So people in the new economy should be smarter and knowledgeable.
