The offensive had already lasted three days, but we had not gained much ground. The division commander instructed our battalion to get around to the rear of the enemy at night and launch a surprise attack. To do so, however, we had to cross marshland and many of us were afraid we might get bogged down in the mud. Our battalion commander decided to take a gamble. Lucky enough, thanks to the severely cold weather which made the marshland freeze over, 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.攻势已经持续了三天，但是我们并没有取得多少进展。师长命令我们营夜晚绕道敌人后方发起突然袭击。然而，要绕道敌人后方，我们必须越过一片沼泽地。我们很多人担心会陷入泥潭之中。我们营长决定冒一下险。所幸由于寒冷天气沼泽地都结上冰，我们于天亮前到达目的地并从敌人后方发起进攻。这一下扭转了战局。地人敌人没有戒备，不久便投降了。 Unit2.

Automobiles have since their invention, revolutionized transportation, changing forever the way people live, travel, and do business. On the other hand, they have brought hazards, especially highway fatalities. However, today the application of computer technology and electronic sensors in designing and manufacturing cars makes it possible to eliminate most of traffic accidents. For example, electronic sensors mounted in your car can detect alcohol vapor in the air and refuse to start up the engine. They can also monitor road conditions by receiving radio signals sent out from orbiting satellites and greatly reduce your chances of getting stuck in traffic jams. 汽车自从发明以来使交通运输发生了革命性的变化，永远的改变了人们的生活，旅行和办事方式，但另一方面也带来了危害，尤其是公路死亡事故。然而现在由于计算机和电子传感器的使用。有可能消除大多数交通事故。例如，装在你汽车上的电子传感器能检测到空气中的酒精雾气并拒绝启动引擎。同样，传感器还能通过在轨道上运行的卫星发出的信号检测路况并大大减少你陷入交通拥堵的可能性。
