     Vampires (吸血鬼)

     Vampire stories go back thousands of years. The acts we now associate with vampires, such as rising

from the grave and drinking blood, were popularized by Eastern European stories. 

     Most early cultures created stories to explain things they didn't understand. For example, hair and nails

continue to grow after people die, which has already been proved possible by modern science.

     These facts were unknown to most people in the 19th century, however. As a result, the legends

surrounding such mysteries were kept alive.

     Count Dracula

     In 1897, Irish writer Bram Stoker's novel Dracula was published, spreading the vampire stories to a mass

audience. In the hovel, the Count Dracula of Transylvania, a 500-year-old vampire, has drunk his country

dry and must move to England in search of new victims. Dracula means "son of the dragon" or "son of the

devil" in Romania.

     Werewolf

     The story of a half-man, half-wolf beast is as old as that of vampires, and almost as varied. In most

werewolf stories, however, a beast would silently enter settlements at night and steal a young child or an

animal.

     The most common explanation of werewolf stories is that the beast was usually an ordinary wolf. The

genetic disorder, which causes too much body hair, may also have helped to popularize the story.

     Frankenstein

     This is a fictional scientist created by British writer Mary Shelly in 1818. Dr. Frankenstein lives m a castle

and is so addicted to making living beings from parts of dead bodies that he refuses to marry.

     The story of Frankenstein may have been planted in Shelly's mind since she visited Castle Frankenstein in

Germany, where an alchemist (炼术士) tried to do experiments with the aim of making people live longer.

     The Invisible Man

     In H.G.Wells' 1897 story, a young scientist called Griffin, manages to make himself invisible. But he

cannot find a way to become visible again. He then wants to make use of his super power but finally has

gone mad. Wells' tale owes a great debt to Greek philosopher Plato's book Republic.
