Which of the following ,if true,most helps to justify the experts' position? 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: yizihuishi 时间: 2012-10-15 20:24
减少10%的flight不会导致delay 建H 将有20%的乘客不去现在的G机场，而该去H机场， 但是，专家认为把H变成机场并不会结束G的delay
选E A 与delay无关 B 比较选项，原文说的是H，这里再说另一个机场之类，无关 C 与commercial 发展有毛关系 D与cost无关 E因为不管加不加H，有些乘客都无法离开G机场，所以还有很多乘客，delay无法结束作者: sqqing911029 时间: 2012-10-15 20:37
