The most traditional definition of a human community was a group of people larger than a family that interact. A community may include people who have at least one common point of interest. In the past, community members lived relatively close to one another in one geographical location: in the same village, town, or city. Nowadays, however, the word community can mean a national, an international, or even an online group of interacting individuals. Therefore, a new definition of community might be a group of people that recognize that they have something in common.

Among 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 in recent years have been based on science fiction stories.It is often thought that science fiction is a fairly new development in literature, but it 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-knownauthors, have been translated into many languages. Modern science fiction writers don't write about men from Mars or space adventure stories. They are more interested in predicting the results of technical developments on society and the human mind; or in imagining future world which are 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 scientific advances. Those who are sufficiently clear-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.Which of the following statements can't prove that science fiction is very popular today 查看材料A.Hundreds of titles are published every year.B.All kinds of people love it.C.Some of the most successful films of recent years have been based on science fiction stories.D.Science fiction can be found in books written hundreds of years ago.
