B C 閱讀測驗1 There he flies, turns, lands and—to da- a disaster is saved, by Superman. “Come on,” you roll your eyes. “That's NOT real.” But admit it -we LOVE superman. Since the debut of the prototypical superhero Superman in 1938, stories of various superheroes have dominated American comic books and crossed over into such other media as films and animations. Versatile as these super characters may be, they do share certain traits. We know the double-life secret that Peter Parker is Spider-man, Bruce Wayne the Batman, and Clark Kent the Man of Steel. The secret identity has a civilian job while the “super-me” puts on an eye-catching costume, or custom-made accessories like Wonder Woman's bracelets. We are concerned that the bad guys play tricks so as to hurt these protectors. Fortunately enough, our superheroes normally have a base to go for “restoration” to. The Batcave has everything the Batman needs. Isn't that great? Furthermore, these super icons may have some backups and do not always have to work independently. The Fantastic Four or X-men team up as they have common origins or sponsors. These super teams are like a marvelous circle. Nevertheless, there are downsides being a superhero. Credits are not always given as the Batman and Spider-man meet with public skepticism or outright hostility. A superhero may even lose control as the Hulk has an issue with his violent alter ego. We love to see the superheroes think big and achieve big. They for sure reflect what we are and what we want to be. In summary, superheroes are popular and iconic because they each represent a large part of a society's traits and values. Everyone can relate to at least one hero and villain, because those heroes are designed to show the best parts of society, and the villains represent the worst parts. 5 What can we say about the author's tone?
