问一道狒狒上的题。。。。

23. On a certain day, nine scheduled flights on Swift Airlines were canceled. Ordinarily, a cancellation is due to mechanical problems with the airplane scheduled for a certain flight. However, since it is unlikely that Swift would have the mechanical problems with more than one or two scheduled flights on a single day, some of the nine cancellations were probably due to something else.

The argument depends on which one of the following assumptions?

 

 

A.        More than one or two airplanes were scheduled for the nine canceled flights.

B.        Swift Airlines has fewer mechanical problems than do other airlines of the same size.

C.        Each of the canceled flights would have been longer than the average flight on Swift Airlines.

D.       Swift Airlines had never before canceled more than one or two scheduled flights on a single day.

E.        All of the airplanes scheduled for the canceled flights are based at the same airport.

 

 

参考答案:A 采用取非法。

思路:否定More than one or two airplanes were scheduled for the nine canceled flights.将削弱作者的结论。

 

 

A:取非削弱

B:无关。

C:无关。

D:无关。

E:无关。

这道题什么意思啊??

文中不是已经说了nine scheduled flights了么?A里为什么还说呢?

flight和plane不是一回事。从理论上说,1、2架飞机也可以一天承担9个flight的任务(来回飞),assumption要在两者之间搭桥,所以A对

恩,谢谢!那再问一下,这里两个scheduled(修饰flight和airplane的)怎么翻译?flight是航班吧?

我觉得题目里However, since it is unlikely that Swift would have the mechanical problems with more than one or two scheduled flights 应该用plane比较好。
