     Superman, Spider-Man, Batman and Iron Man....There is no shortage of superheroes. You find them in

comic books, on the TV and the big screen.

     In a survey of fans by the sci-fi (科幻) and fantasy website, SFX.co.uk, Batman, 70 years old this year,

was voted Britain's favorite superhero.

     Unlike many crime-fighting superheroes Batman has no special powers. He can't fly like Superman or

shoot a sticky (粘性的) web like Spider-Man.

     Bruce Wayne is born to a wealthy Gotham City business family. However, when his parents are murdered

his life changes completely.

     Wayne feels anger at their deaths and guilty that he did not prevent them. He travels around the world

learning how to fight. Upon returning to Gotham, he creates a disguise (伪装) to enable him to fight crime

without being recognized.

     A childhood fear of bats leads him to choose to dress as one. His idea is that through the bat persona (角

色) he can prove to himself that he has overcome his childhood fears.

     Wayne is the CEO of the company he inherits (继承) from his father. He seems to live the lifestyle of a

millionaire playboy. But this is a ruse (计策). He works hard at the image to allow himself the freedom he needs

to do his work as a crime fighter. "Bruce Wayne, playboy" is the disguise(伪装); Batman is the real person.

     "Wayne is not a born superhero. Instead, he is a real, complex person," said Dace Golder, editor of the

website. "He is the most realistic of all the superheroes. I am particularly interested in the emotional process

by which a boy becomes a hero. His superhero qualities come from within."
