【逻辑精选25练】GMAT官方CR真题实例讲解（第十练）

GMAT逻辑题一直以来是不少考生的弱项，因为逻辑题考查的不只是考生对于英文题目的阅读和理解能力。考生必须具备一定的逻辑推理思维能力才能做好此类题目。下面小编就通过一些GMAT逻辑真题的完整分析来为大家讲解这一难点题型的解题思路和技巧。

例题分享：

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 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 Greentown airport 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.

题目翻译：

只有减少G地机场现有航班量的10%，才能避免飞机延误情况的出现。H简易机场在G地机场的40英里之外。如果可以对其进行升级与扩建的话，它可以成为20%现在用G地机场乘客的另一选择。然而，专家们并不支持将H简易机场扩建成全方位服务机场可以解决G地飞机延误问题这一说法。

解题思路：

找到G地的乘客不会去H的原因。

逐项分析：

A、把H变成一个全方位服务机场不仅需要对机场进行建设，还需要对配套高速公路进行建设。无关项。

B、相较于H来说，G周边第二大的简易机场会对G地的乘客更具吸引力。无关项。

C、H机场坐落于一个相对欠发达的地区，但是如果H成为全方位服务机场的话，将会吸引大量的商业与住宅开发。无关项。

D、如果飞机需要等待着陆的话，额外需要的燃油将会大大增加航空公司的成本。无关项。

E、正确选项。因为G是一个地区性的中转站，那么即使H地的机场建成了，因为其没有中转航班，并不能达到旅客分流的目的。

正确选项：

E
