34、alone at this stage and concentrate on the window.A cars electrical system should work for up to three minutes in water, so try the method of opening it electronically first.Many people dont think about the window as an escape option either because of panic or misinformation about doors and sinking.

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。
