First: The Ice DefenderIn 1812,Napoleon Bonaparte, Emperor of the French, led his Grand Army into Russia. He was prepared for the fierce resistance of the Russia people defending their homeland. He was prepared for the long march across Russia soil to Moscow, the capital city. But he was not prepared for the devastating enemy that met him in Moscow – the raw, bleak Russia winter. In 1941, Adolf Hitler, leader of Nazi Germany, launched an attack against the Soviet Union, as Russia then was called. Hitler’s military might was unequaled. His war machine had mowed down resistance in most of Europe. Hitler expected a short campaign but, like Napoleon before him, was taught a painful lesson. The Russia winter again came to the aid of the Soviet soldiers.1812年，法国皇帝拿破仑·波拿巴 率大军入侵俄罗斯。他准备好俄罗斯人民会为保卫祖国而奋勇抵抗。他准备好在俄罗斯广袤的国土上要经过长途跋涉才能进军首都莫斯科。但他没有料到在莫斯科他会遭遇劲敌—俄罗斯阴冷凄苦的寒冬。1941年，纳粹德国元首阿道夫·希特勒进攻当时被称作苏联的俄罗斯。希特勒的军事实力堪称无敌。他的战争机器扫除了欧洲绝大部分地区的抵抗。希特勒希望速战速决，但是，就像在他之前的拿破仑一样，他得到的是痛苦的教训。仍是俄罗斯的冬天助了苏维埃士兵一臂之力。 Two: Smart CarsTwo of the most frustrating things about driving a car are getting lost and getting stuck in traffic. While the computer revolution is unlikely to cure these problems, it will have a positive impact. Sensors in your car tuned to radio signals from orbiting satellites can locate your car precisely at any moment and warn of traffic jams. We already have twenty-four Navstar satellites orbiting the earth, making up what is called the Global Positioning System. They make it possible to determine your location on the earth to within about a hundred feet. At any given time, there are several GPS satellites orbiting overhead at a distance of about 11,000 miles. Each satellite contains four atomic clocks, which vibrate at a precise frequency, according to the laws of the quantum theory.As a satellite passes overhead, it sends out a radio signal that can be detected by a receiver in a cars computer. The cars computer can then calculate how far the satellite is by measuring how long it took
