Translation
The offensive had already lasted three days, but we had not gained much ground. Our troops engaging 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 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 20degrees 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.

Translation
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.
