问题 How do the airlines expect to prevent commercial plane crashes? Studies have shown that pilot error contributes to two-thirds of all such crashes. To address this problem, the airlines have upgraded their training programs by increasing the hours of classroom instruction and emphasizing communication skills in the cockpit. But it is unrealistic to expect such measures to compensate for pilots’ lack of actual flying time. Therefore, the airlines should rethink their training approach to reducing commercial crashes. Which one of the following is an assumption upon which the argument depends?
选项 A、Training programs can eliminate pilot errors.
B、Commercial pilots routinely undergo additional training throughout their careers.
C、The number of airline crashes will decrease if pilot training programs focus on increasing actual flying time.
D、Lack of actual flying time is an important contributor to pilot error in commercial plane crashes.
E、Communication skills are not important to pilot training programs.
答案D
解析 航空公司通过采用增加课堂教育时间和强调飞行员通讯技巧的训练方案来防止商业飞机的坠毁。本题的结论为这些措施不能补偿飞行员实际飞行时间的缺乏，也就是说实际飞行时间的缺乏是飞行员在商业飞机坠毁事故中失误的最主要的原因。所以(D)为正确选项；(A)是不对的，因为训练计划只能减少飞行员的失误，并不能消除飞行员的失误；(B)与本题的结论无太大的关系；(C)是本题的迷惑选项，它虽然在某种程度上也具正确性，但是它没有指明是缺乏实际飞行时间还是缺乏课堂教育及通讯技巧是造成飞机坠毁的主要原因，因此从(C)得不出本题的结论；(E)本身就具有逻辑错误，对飞行员训练计划不主要的东西不一定就不重要，很难想象没有通讯技巧的飞行员能安全地驾驶一架飞机。
