19. 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?
(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.

这道题目答案为d。 我选择c 。我认为是原文 后两局的缩写。 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.
我不知道为什么错了。

已讨论过，请搜索。关键理解结论是their training approach 不能解决 pilot error。而不是不能reducing commercial crashes。

但是题干最后说的是should rethink their training approach to reducing commercial crashes.

虽然知道D肯定对，但是不知道如何排除C。把C加了否定词好像也排除不了。

另外，如果不麻烦的话，能不能请版主把以前讨论的链接给一下？我实在搜不到。

将C取非， if pilot training programs focus on increasing actual flying time，the number of airline crashes will not decrease 。可能出现的情况是pilot error 导致的CRASHES已经减少，但其他导致因素的CRASHES增加，从而导致the number of airline crashes（总体） will not decrease，也即该培训项目还是起作用，还是达到了原来设该培训项的目的To address this problem（pilot error contributes to two-thirds of all such crashes），所以不需要rethink their training approach 。即结论不能成立。

太感激版主了！这下彻底明白了。严重感谢！！！
