Spiderman(蜘蛛侠) is one of the most famous comic book heroes of all time. He was created by Stan Lee in 1963 and was first introduced to the world in the pages of Marvel comic books.

Spiderman’s story is the story of Peter Parker, a child who lost his parents and lives with his aunt and uncle. Peter is a shy, quiet boy wearing glasses and has few friends. One day, on a high school class trip to a science lab, he gets bitten by a special spider. Soon Peter realizes he has amazing powers: he is as strong and quick as a spider and also has a type of sixth sense. He no longer needs his glasses and he can use his super power to fly through the city streets! Remembering something his Uncle Ben has told him, that “with great power, there must also come great responsibility(责任),” Peter decides to use his powers to fight enemies(敌人) who do cruel things to people. And so, Spiderman is born.

Life is not easy for Peter even though he is a superhero. He is in love with Mary Jane but cannot tell her about his amazing powers. Besides, his best friend Harry hates Spiderman! Peter is also short of money and time. He has to sell photos of Spiderman (himself!) to a newspaper and he keeps losing his other jobs because he’s so busy saving people! Yet he has to fight different kinds of cruel enemies.
