As a domain expert in comic book lore, I can tell you that Spider-Man's origin story has been depicted in various ways across different media, but the most well-known version comes from the comics.

English Answer:
Spider-Man, whose real name is Peter Parker, was bitten by a radioactive spider during a science exhibition. This spider had been altered by radiation, which granted it the ability to crawl on walls and a heightened agility. The bite transferred these abilities to Peter, along with the "spider-sense" that alerts him to danger. This incident marked the beginning of Peter Parker's journey as Spider-Man, as he learned that "with great power comes great responsibility."

Chinese Translation:
蜘蛛侠，真名彼得·帕克，在一次科学展览会上被一只放射性蜘蛛咬伤。这只蜘蛛因辐射而发生了变异，获得了在墙上爬行和增强的敏捷性。这次咬伤将这些能力转移到了彼得身上，同时他还获得了一种名为“蜘蛛感应”的能力，能够在危险来临前给予他警告。这一事件标志着彼得·帕克作为蜘蛛侠的旅程的开始，正如他所学到的那样，“能力越大，责任越大”。
