77. 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 airline 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?



A.Training programs can eliminate pilot errors.

B.Commercial pilot 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.

答案是 D 我选的C 为什么不对呢 小NN 就可以帮我了

我说说我的理解吧！我没上过班，都是自己的理解，解释起来有点费劲，凑合着看吧！

我理解assumption是联系，前提和结论的，Argument=premise+assumption+conclusion

premise: Studies have shown that pilot error contributes to two-thirds of all such crashes.

conclusion:Therefore, the airlines should rethink their training approach to reducing commercial crashes.

assumption就是连接这2个的，猜测答案是连接training—pilot error—crash，所以必然跟pilot error有关，因为pilot error直接导致crash，文中又说真正飞行时间才是最大的原因，所以就是 真正飞行时间—pilot error—crash的连接

C中虽然说了增加飞行时间会减少crash，但它没说为什么增加飞行时间会减少，就是推理断了一层你能感觉到吗？我说不清楚！！如果加一句：并且增加飞行时间可以减少pilot error就可以了。关键就是没提前提pilot error

D中说了缺少飞行时间导致error,然后导致crash.就是很完整的推理了！

我的理解是这样，也不知道对不对。与你分享！你也可以跟我交流，因为我也不是很懂。懵懵懂懂的。

我没有感受到啊啊！囧 我是用的取非削弱方法 这样一来 很明显低削弱了啊 我感觉这两个选项是读可以的 但是就是不明白哪个跟好呢

C.The number of airline crashes will decrease if pilot training programs focus on increasing actual flying time.

C merely rephase the premise given in the argument i think.

"To address this problem (crashes), blablablabla. But it is unrealistic to expect such measures to compensate for pilots’ lack of actual flying time." ==> in other words, it says "actual flying time will address the problem".

the underlying assumption is D. argument focuses on actual flying time will reduce accidents w/o mentioning the relationship between these two.
