Unit1攻势已经持续了三天，但是我们并没有取得多少进展。我们在前线与敌人交战的部队遇到了强力的抵抗。师长（DIVISION?COMMANDER）命令我们营（BATTALION）绕到敌人后方发起突然袭击。然而，要绕到敌人后方，我们必须越过一片沼泽地（MARSHLAND）。我们很多人担心会陷入泥潭之中。我们营长决定冒一下险。我们在夜幕掩盖下出发，不顾困难，奋勇向前。幸运的是，夜间温度突然下降到摄氏零下20度，烂泥地都结上了冰。由于这寒冷的天气，我们于天亮前到达并从敌人后方发起进攻。这一下扭转了战局。敌人没有戒备，不久便投降了。?The?offensive?had?already?lasted?three?days,but?we?had?not?gained?much?ground.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,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.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.Unit2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?industrialised?nations.They?are?indeed?of?great?use?to?us,but?they?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?satelliteaided?global?positioning?system?(GPS),a?computer?in?the?automobile?can?locate?the?vehicles?precise?position,and
