所以取有效位數一定要四捨五入嗎? 做例題發現答案都有四捨五入 但題目沒有註明需要四捨五入

1 2. 3 4. D) Basically, they go on voyage after voyage in search of an immense treasure buried somewhere by the King of the Pirates, Gol D. Roger. 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? (A) Angry. (B) Formal. (C) Harsh. (D) Relaxed. 48 主题5 藝文世界

Although scientists have not been able to solve all the mysteries of this amazing organ, they have made for learning, memory, and language. Recent studies indicate that the two progress. They have found that certain parts of the brain are halves of the brain -- the right hemisphere and the left hemisphere play extremely important roles in learning and communicating. The left hemisphere deals with rules, lists of information, and short-term memory. In contrast, the right hemisphere deals with feelings, colors, and term memory. Scientists recognize the importance of both hemispheres in individuals learn languages.
