A选项：首先，代词it的指代对象只能是单数名词，并列连词but身后的句子是被动语态，主动语序为：
a joint Canadian-Russian study found it to be both feasible as well as desirable.
在逻辑上，被发现是“可行的”且“令人满意的”应该是“每年开放这些航线给更多的飞机”这件事，而不是某个单数名词（代词只能指代名词，不能指代句子）。
其次，found不论是主动还是被动，宾语和宾语的补足语部分都不能用不定式短语，应该用从句或ing形式来表达，这点考查了不定式和从句的区别。由于find的约束力较弱，所以其宾语和宾语的补足语不能用不定式to be的形式。
再次，both…and…是固定搭配，不能用both…as well as…。

B选项：本选项句首的currently used by only two or three planes a day是一个过去分词短语，在句中必然是伴随状语，其逻辑主句和其所修饰的句子的主语相同，即，a joint Canadian-Russian study。但在逻辑上，“每天被2~3个飞机用”的应该是“航线”，而不是“研究”。
另外，代词it的指代对象有误同选项(A)。

C选项：本选项没有谓语动词；代词 it的指代对象有误同选项(A)；find的宾语补足语部分都不能用不定式短语错误同选项(A)；both…as well as…错误同选项(A)。

D选项：Correct. 本选项在语法和逻辑上均是正确的。

E选项：本选项句首的with短语是独立主格结构，这里没有任何问题。真正的错误出现在主句上，其主动语序为：
a joint Canadian-Russian study found opening those routes to thousands more commercial planes a year as both feasible and desirable.
find身后只能用宾语从句，不能用宾语+宾补的形式。这点类似于不定式和从句的区别，英语中通常允许在“宾语”和“宾补”间补上to be以突出两者的关系，例如：
(1) I put a book on the table.
(2) I put a book to be on the table.
这两个例句的语意基本相同。由于find的约束力较弱，所以身后不能用不定式短语的形式。

A.首先原句逻辑没错，但是原句both...and的固定搭配用错，排除。题干意思是北极地区的交通运输线路目前每天只有2-3架飞机会使用，但是，一个有加拿大及俄罗斯共同合作的研究表明，如果这些线路每年能供千万架商业飞机使用的话，这将会是非常值得且可行的。
根据逻辑角度可以排除B,C,E 所以，正确答案是D。
B：失去原文的转折逻辑，并且，study发不出use的动作，排除。
C：逻辑意思改变，且无谓语动词。Both and 搭配不对。并且给人的感觉是study发出的find的动作，不对，排除。
E，opening those routes to thousands more commercial planes a year has been found by a joint Canadian不符合表达习惯，排除，且失去原文的转折关系，排除。

5. 在南极上空的空中交通路线现在一天只被两到三架飞机使用，但是一个联合加拿大与俄罗斯的研究发现如果这个路线一年开放给数以千计的商业飞机既是可行的也是有价值的。 A 代词it指代单数名词，不能指代整个句子，是这件事令人满意不是一个单独的名词令人满意，find to do不用，用find that从句，both and是固定搭配，as well as 不行 B 代词歧义，分词短语的逻辑主语和所修饰的句子主语相同 C find that才对， both and, which就近修饰，缺谓语 D 对 E 状语结构svo,doing优于独立主格，独立主格修饰整个句子，把主句的被动语序转成主动以后发现find doing是错的，只能是find that

错选B B选项，前半句used by...主语只能是air routes 很明显的错误正确选项D 因为although犹豫，直接误以为是乱加因果排除了 E被动不优 A/C both...as well as 排除错误原因总结：做题时看到全划线的句子心中发怵，想快点选出答案，没有具体分析每一个选项的语意！

朋友醒醒

B:used后面要立刻给出一个可以与之搭配的主语

小乌鸡爪子

句意：空中交通线路在NP现在每天只被2-3架飞机使用，但CR研究发现如果这些线路被开放给更多的商业飞机每年，会变得不仅可行的，而且值得拥有的。 A：both ..., as well as ...排除。 B：Used by only two or three plants 的主语是joint CR study。主语不对，错误。 C：CR, (finding ...) ... 没有谓语，错误。 D：正确。 E：has been found 主动优先被动。排除。

原句中错误在于both搭配and，不是as well as A.both 不能和as well as连用，排除 B.缺失了主语，不知道 used被谁发出 C.both 和as well as不能连用，排除 D.让步引导的主句主谓宾都有，主语是Air traffic routes，谓语are used 表示被动，宾语planes，后面的宾语从句中，that引导部分解释found，opening和joint study 构成主动关系，且both...and保持了两边都是形容词形容前面的commercial planes，选它没毛病 E.With 只能加名词（这种情况有时候with被省略），或者with+名词+doing/done（表示主被动的关系），并且opening会有歧义，让读者以为是指代亲们的routes，但实际上是后面的joint canadian-russian study发出的动作

学不下去太难了

the correct structure recognized by the GMAT is “both A and B.” The GMAT views the structures “both A and also B” and “both A as well as B” as redundant and incorrect.

A的最根本问题不是It无所指，而是idiom运用错误，应该是it was found that，不是 it was found to be，前者的it只是placeholder，不需要指代，而是后者真的需要有指代的东西，下面例句 It was found that the sick dog was dead. Although the sick dog was in good condition, it was later found to be dead.

E选项，as使用不当。如果还原一下，就是，the study found opening as feasible and desirable。明显不对。
