38、 the sooner the window is open, the sooner you can escape directly through it.文章大意：本文为说明文，主要介绍了当遇到汽车掉入水中时，人们应该如何应对。解析：1根据横线前的“an accident in which your vehicle is thrown into the water你的汽车掉到水里去了”与D项中的“Such accidents”对应，可知这样的事故中的乘客会有被淹死的危险。而空格处句子与空格后一句为转折关系，故选择D项。2根据横线前句“Undo your seatbelt.松开安全带”与F项中
39、的“This is the first thing to attend to”对应，可知当汽车掉进水里的时候，首先我们要解开安全带，但是在惊慌的时候，人们经常会忘记这一点。故选择F项。3根据本段中的“concentrate on the window”和“Many people dont think about the window as an escape option either because of panic.”建议我们要注意窗户，因为我们可以把窗户当成逃生的地方。可知选择A项。4首先空格前句与空格处为转折关系，本段仍旧围绕“window”进行阐述，G项所表达的意思为打开窗户逃生，与本段主旨一致，故选择G项。5空格前的“car cabin has been filled with water”与C项中的“fill up with water”对应，而C项所表达的意思也与空格后的“While there is still air in the car”相关联，故此题选择C项。
