A short story is shorter than a novel, but longer than a poem, usually between 1000 and 2000 words long. it tells a story which can usually be read quite quickly. it often concentrates on one, central event; it has a limited number of characters, and takes place within a short space of time.
Reading authentic literary texts can be difficult. They may contain grammatical structures you have not studied, or expressions and sayings you are not familiar with. Unlike graded readers, they have not been written for language students. The words have been chosen to create a particular effect, not because they are easy or difficult.
