Only a reduction of 10 percent in the number of scheduled flights using Greentown's airport will allow the delays that are so common there to be avoided.Hevelia airstrip ,40 miles away,would ,if upgraded and expanded,be an attractive alternative for fully 20 percent of the passengers using Greentown airport.Nevertheless,experts reject the claim that turning Hevelia into a full-service airport would end the chronic delays at Greentown.
Which of the following ,if true,most helps to justify the experts' position? A.Turning hevelia作者: sqqing911029 时间: 2012-10-15 19:32
A.Turning Hevelia into a full-service airport would require not only substantial construction at the airport itself,but also the construction of new access highways. B.A second largely undeveloped airstrip close to Greentownairport would be a more attractive alternative than Hevelia for many passengers who now use Greentown. C.Hevelia airstrip lies in a relatively undeveloped area but would ,if it became a full-service airport,be a magnet for commercial and residential development. D.If an airplane has to wait to land,the extra jet fuel required adds significantly to the airline's costs. E.Several airlines use Greentown as a regional hub,so that most flights landing at Greentown have many passengers who then take different flights to reach their final destinations.作者: lovechun 时间: 2012-10-16 04:40
同问啊,为什么E选项就能说明把HEVELIA变成了full-service的机场不能结束GREENTOWN的延误了啊。。。就算GREENTOWN是regional hub也不能说明就延误吧。。。我晕乎死了。。求NN!!作者: jiangvss 时间: 2012-10-18 11:54 标题: 不知道这么想对不对,仅供参考 我的思路是这样的啊,仅供参考 reduce 10% number of flights in G -----> avoid delays Hevelia upgrade -----> reduce 20% passengers in G 就看passenger 和 flights number的关系了
A. Highway construction - 无关 B. 另一个跑道比H还好 - 无关比较 C. 没justify D. airline cost - 无关 E. 大多数航空公司的航班passengers在G这个机场转机,所以不会减少number of flights,那就避免不了延误作者: charlesyu 时间: 2012-12-14 06:57
E 正因为大多数是转机,因此可以换到Hevelia(在哪里转机很重要么?),如果大多数人目的地都是到G机场附近的话,反而不能换新机场,不能降低flights。 B 增加一个新跑道,肯定会减少flight delays,效率提高了嘛,怎么会是无关呢?
我觉得你说的有道理 但og的解释说Airlines generally use certain airports as regional hubs--an airport through which an airline routes most of its traffic...我的理解是因为这里是中心,很多航线在这里,机场要是不让一些航班经过就会使得航空公司routes不畅,所以不能减少G机场的航班。请问我这样理解的对吗?作者: cderzmh 时间: 2014-3-1 11:28
