Spiderman 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 against enemies 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 he can’t 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 against different kinds of cruel enemies.

当今世界,文化软实力在综合国力竞争中的作用愈来愈凸显。一个国家如何增强自身的文化软实力?从文化的对外交流上看,首先要解决阐释力问题。要对国际社会解释中国社会发展的正当性,靠什么解释?意识形态是一方面,更重要的是要把文化的全部功能属性发挥出来,多层面、全方位去“风雨化人”。其次是解决参与力问题。现代中国文化走向世界,不仅要成为世界文化百花齐放中争奇斗艳的一枝奇葩,更要成为世界文化演进中大有作为的参与者。为世界文化注入“中国元素”,提供“中国理念”。
