     Now net fiction (小说) , also called computer fiction is

popular in more than 80 countries.

     To write computer fictions, the writers don't have to think

about making any plot. Like reporters, they just go to a lot of

places and collect materials: what most women want, their ideas

about life and love, their happiness and sufferings and emotions.

All these materials are fed into the computer to be processed (处

理) and classified (分类). Then the writers just pick some

materials from every part and fill in some details (细节)  and a

story is made up.

   The first computer fiction was edited by 13 editors and

published in Canada in 1976.  It was a great success and 45 million

copies were sold. Seeing this new process as profittaking (赢利

的) , a big American publishing company bought over the majority

of the 13 Canadian editors and soon a series of computer fictions

were published in the United States.

          All the computer fictions have very romantic (浪漫的)  titles.

The heroine(女主人公)  is always about 20, while the hero is a

30 to 40 bachelor(单身的) , handsome, with money and power.

The hero and the heroine have a happy reunion(团聚) after all

kinds of misunderstandings(误会). Computer fictions are enjoyed

by most women readers of the west. But people doubt if they have

any literary value(文学价值).
