一眼这些车辆的引擎盖，就会发现一个有毒的秘密:每辆嘟嘟车都是由五块巨大的铅酸

电池驱动的，总共含有近300磅的铅。每一年半左右，当这些电池需要更换和回收

时，大约有60磅的铅泄漏到环境中。电池回收通常在不受监管的小型工厂进行，这是

effortstoavoidthepossibilityofalargerfailure?（你有没有因为害怕某件事失败而决定根

本不去尝试？还是对失败的恐惧意味着，在潜意识里，你破坏了自己为避免更大失败

的可能性所做的努力）”讲述了人们害怕失败的现象和背后的心理因素，再结合下文“I六

importanttorealizethatineverythingwedo,there'salwaysachancethatwe511fail.（重要的

是要认识到，在我们所做的每件事中，总会有失败的机会）”，该空应该讲失败存在的

普遍性，D选项“我们中的许多人可能曾经经历过这种情况。”切合语境，也可引出下

文讲人总会有失败的时候。故选D。

②由小标题“Analyzeallpotentialoutcomes.（分析所有潜在结果。）“可知本段主要讲减

少人们对失败恐惧的方法之一一分析事情将产生的所有（好坏）结果，该空应该要分析
