Aristotle

   the Famous Greek Thinker and Scientist

        We have read many stories about navigators（航海家）, pilots（飞行员） and astronauts（宇航员）. Today, let's learn something about Aristotle - the famous Greek（希腊） thinker and scientist.

　　Aristotle was born in 394 B.C.（公元前） in northern Greek. His father was a physician（医师）. But when he was still a little boy, both his parents died. At the age of 17, he went to Athens（雅典） to study at Plato's（柏拉图，古希腊哲学家） school. He worked hard to study philosophy（哲学） and science. He stayed there for 20 years, first as a student, later he became a lecture（讲师） and at last he was a scientist. In 342 B.C., Aristotle became Alexander's teacher. After Alexander became Alexander the Great（亚历山大大帝）, in 335B.C., Aristotle returned to Athens and set up his own school. Twelve years later, when Alexander died, the Athenians wanted to kill him. Aristotle left Athens and died in 322.B.C.

　　As a scientist, Aristotle was famous for his theory that the earth was at the center of the universe（宇宙）. It was composed of the four elements（元素）: earth, water, air and fire.

        我们已经读了许多航海家，飞行员和宇航员的故事，他们都是探险家。从今天开始，我们来看看另一种探险家--人类思想的探索者的故事。今天向大家介绍的是古希腊哲学家和科学家 -- 亚里士多德。

　　公元前384年，亚里士多德出生在希腊北部一小城。他的父亲是名医生。但是在他还很小的时候，父母双亲就去世了。17岁时，亚里士多德来到雅典城，在大哲学家柏拉图的学校学习。它天资聪颖，又很刻苦，进步很快。他在学校里呆了20年，先是当学生，后来做讲师，最后成为哲学家和科学家。公元前342年，亚里士多德应邀来到马其顿王国，成为亚历山大的老师。公元前335年，亚历山大登基，他就是历史上著名的亚历山大大帝，亚里士多德回到雅典，开办了一所学校。但是12年后，亚历山大大帝逝世。由于与亚历山大和马其顿贵族的密切关系，一些希腊人想杀死亚里士多德， 他只好逃往国外，第二年在国外去世。

　　亚里士多德提出了著名的地心说。他认为地球由土，水，空气和火四种元素构成。
