标题: 狒狒135 －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 我怎么觉得C 也对那我现在做假设题都是取非但是我发现C 也能起到破坏作用阿？？？

正确答案说C 是加强唉我总是错

因为C没有直接回答原因，Q说pilots’ lack of actual flying time，我也觉得C,D都可能对，但是只选一个，当然选D，因为它直接对应Q里的原因，而C还要推一下。跟GWD的“白痴”原则不配套（其实我觉得GWD的“白痴”原则很撤）

做这题我的思路是，读完题就知道，关键是 actual flying time

在选项里找，找到C，D两项。

C有可能depends，但D一定是depends

1.因为C答案放大了scope，原scope是commerical airplane crashes

2.理所当然认为training program包括actual flying，在题干中并没有说到有包括。

这两点使得C比较牵强。

至于2楼所说的conclusion与assumption的关系，我觉得不是那么重要，我觉得conclusion也有可能是assumption

Situation:

Increasing the classroom training and emphasizing the communication skills can't compensate pilot's lack of actual flying time, thus can't reduce the

possibility of pilot error. so the method should be rethinked.

Reasoning: Since actual flying time is a more important factor than classroom training time and communication skills in solving the problem of pilot error, it must be assumed that lack of actual flying time have close relationship with pilot error. D fill the gap.

C although point out a relationship between lack of actual flying time and plane crashed , but it not necessarily assumed, for the relationship is not so fixed which rule out other factors that may also affect the incidence of plane crashes.
