GMAT  Official Guide是每一个考GMAT的学生必须具备的书籍。里面的每一道题目最好做2遍以上(尤其是错题,一定要好好分析体会)。很多同学告诉我,OG的答案不够清楚。事实上,OG的有些讲解试图绕开一些需要补充的知识,例如什么是溯因推理,分词的用法等等,因此往往显得不够清晰。因此,我想我每天抽出一些时间,写一道OG的题目,帮助大家学习。

7. Air traffic routes over the North Pole are currently used by only two or three planes a day, but it was found bx a joint Canadian-Russian study to be both feasible as well as desirable if those routes are opened to thousands more commercial planes a year.

A. Air traffic routes over the North Pole are currently used by only two or three planes a
day, but it was found by a joint Canadian-Russian study to be both feasible as well as
desirable if those routes are opened to thousands more commercial planes a year.
B. Currently used by only two or three planes a day, a joint Canadian-Russian study has
found that if air traffic routes over the North Pole are opened to thousands more
commercial planes a year, it would be both feasible and desirable.
C. joint Canadian-Russian study, finding it to be both feasible as well as desirable to
open air traffic routes over the North Pole, which are currently used by only two or
three planes a day, to thousands more commercial planes a year.
D. Although air traffic routes over the North Pole are currently used by only two or three
planes a day, a joint Canadian-Russian study has found that opening those routes to
thousands more commercial planes a year is both feasible and desirable.
E. With air traffic routes over the North Pole currently used by only two or three planes a
day, opening those routes to thousands more commercial planes a year has been found
by a joint Canadian-Russian study as both feasible and desirable.

这是一道全划线题,在GMAT中一般全划线题是难题,因此考试的时候如果遇到,你应该高兴才对,因为说明你进入了高分段。

首先,读完这句话,理解意思,it作为形式主语指代后面的不定式to be both feasible as well as desirable表意是错误的(illogical)。而且both…as well as…也是错误的平行对称结构,同样的问题也出现在C.

而扫描的时候,我发现B中,Currently used by… 是过去分词做状语,其逻辑主语是修饰的动词has found的主语,即a joint Canadian-Russian study。这是illogical的,因为意思是study is used by two or three planes a day。

E中found study as both feasible and desirable是错误的,这里的as是介词,后面跟介词宾语,原文意思为both a feasible and a desirable way,但这个way前面没有,因此也谈不上省略。
因此答案是D。
