Science FictionAmong the most popular books being written today are those which are usually classified as science fiction. Hundreds of titles are published every year and are read by all kinds of people. Furthermore, some of the most successful films of recent years have been based on science fiction stories.It is often thought that science fiction is a fairly new development in literature, but its ancestors can be found in books written hundreds of years ago. These books were often concerned with the presentation of some form of ideal society, a theme which is still often found in modern stories.Most of the classics of science fiction, however, have been written within the last hundred years. Books by writers such as Jules Verne and H.G. Wells, to mention just two well-known authors, have been translated into many languages. Modern science fiction writers don’t write about men from Mars or space adventures stories. They are more interested in predicting the results of technical developments on society and the human mind; or in imagining future world which is a reflection of the world which we live in now. Because of this, their writing has obviously political undertones.In an age where science fact frequently overtakes science fiction, the writers may find it difficult to keep ahead of science advances. Those who are sufficiently clearly- sighted to see the way we are going, however, may provide a valuable lesson on how to deal with the problems which society will inevitably face as it tries to master its new technology.Main idea of the paragraphsDetails of the relevant paragraphThe popularity of science fictionScience fiction stories are among the most popular books.They are published (1) and are read by all kinds of people.The origin of the science fictionIn fact, science fiction is not a (2) in literature.
