The airline's proposed purchases of as many as 250 medium-range planes will probably be the basis of an overhaul of its routes; it is expected that they will increase the number of direct point-to-point flights, instead of continue to use feeder aircraft to bring passengers to major hubs.

考题讲解

题目分析:
首先我们能看到(A)(B)中的it是形式主语,其等价于:That it will increase the number of direct point-to-point flights, rather than to continue to use feeder aircraft to bring passengers to major hubs is expected;其次,我们可以发现平行触发语rather than/instead of。

选项分析:

A选项:代词they是一个复数代词,指代对象必须是复数名词,这里只能指代purchases或者planes,但是在逻辑上,增加航班数量的应该是航空公司(airline是单数名词)。另外,expect的逻辑宾语(句法上是is expected的主语,但实际上这个从句是expect的逻辑宾语)应该用不定式短语to increase the number of direct point-to-point flights而不是从句that they will increase the number of direct point-to-point flights。这点考查了不定式和从句的区别。用之于本题,expect的约束力较强,应用不定式宾语
另外,instead of是介词,身后只能加名词或动名词,所以不能用instead of continue,至少要改为instead of continuing。

B选项:从句that it will increase the number of direct point-to-point flights应改为不定式短语,该错误同选项(A);increase和continue在语法上不平行。

C选项:从句that the number of direct point-to-point flights will increase应改为不定式短语,该错误同选项(A);increase和continue平行错误同(B)。

D选项:Correct. 本选项在语法和逻辑上均是正确的。

E选项:increase和continue平行错误同选项(B)。
