      Science fiction and fantasy are interrelated,and it can be hard to tell the difference between

the two.The two terminologies (术语)have been widely discussed,and it is very difficult to draw

a line between the two.In the words of great writer,Issac Asimov,science fiction is based on

technology and science and is possible.Science fiction can be about robots and space and has

its bases in science.On the contrary,fantasy is only imaginary,and involves things that do not

exist in real life.Fantasy can be about talking animals or something immortal.Science fiction

shows things that could possibly take place in the real world.Fantasy adds realism to things

that are unlikely to happen.

      When compared to fantasy stories,the imaginary elements in science fiction can largely be

possible.Though the topic in science fiction can be contrary to reality,these stories are based

on some fact that is absent in fantasy.Unlike science fiction,fantasy uses supernatural forms

and magic in its topic.

     Science fiction can be divided into different kinds,such as hard science fiction,soft science

fiction,social science fiction,time travel,military science fiction,super human fiction and space

fiction.Fantasy can be divided into horror fiction,mystery fiction,super hero fiction and

community.

      However,as fantasy fiction becomes more focused on modern environments,rather than

ancient worlds,technology plays an increasingly important role in the stories,thus leading to the

birth of Science Fantasy,just in time to meet the audience mourning a slowdown of Science

Fiction.
