Our troops engaging the enemy at the front were faced with strong/fierce/stiff resistance. The division commander instructed our battalion to get around to the rear of the enemy and launch a surprise attack. To do so, however, we had to cross a marshland and many of us were afraid we might get bogged down in the mud. Our battalion commander decided to take a gamble. We started under cover of darkness and pressed on in spite of great difficulties. By a stroke of luck, the temperature at night suddenly dropped to minus 20 degrees Celsius and the marsh froze over. Thanks to the cold weather, we arrived at our destination before dawn and began attacking the enemy from the rear. This turned the tide of the battle. The enemy, caught off guard, soon surrendered. Unit 2 汽车在二十世纪改变了世界，尤其是在美国和其他工业国家。汽车确实对我们大有用处，但也带来了一些危害，比如声音污染、空气污染以及公路死亡事故。据报导汽车事故被列为全世界导致死伤的主要原因之一。可庆幸的是，现代发明家们正在重新发明汽车。新的推进系统（PROPULSION SYSTEM）、燃料、设计以及制造汽车的手段在过去的十年中得到迅速发展。例如，通过使用卫星辅助的全球定位系统，汽车里的计算机能给汽车精确定位；随着遥感器的应用，智能汽车能排除不少汽车事故。 Automobiles changed the world during the 20th century, particularly in the United States and other industrialized nations. They are indeed of great use to us, but they have brought some hazards as well, such as noise and air pollution, and highway fatalities. It is reported that automobile accidents rank among the leading causes of death and injury throughout the world. Fortunately modern innovators are reinventing the automobile. New propulsion systems, fuels, designs, and means of manufacturing cars have all developed rapidly in the past decade. For example, by using the satellite-aided global positioning system (GPS), a computer in the automobile can locate the vehicle's precise position, and with the application of sensors, smart cars can eliminate most car accidents.
