og112悬而未决得问题

112. Domestic automobile manufacturers have invested millions of dollars into research to develop cars more
gasoline-efficient even than presently on the road.
(A) into research to develop cars more gasoline-efficient even than presently on the road
(B) into research for developing even more gasoline-efficient cars on the road than at present
(C) for research for cars to be developed that are more gasoline-efficient even than presently the road
(D) in research to develop cars even more gasoline-efficient than those at present on the road
(E) in research for developing cars that are even more gasoline-efficient than presently on the road

答案d选出来不难而且没有疑问

难得是如何理解解释中

In A, the phrase
more gasoline-efficient ... than presently on the road does not identify the second term of the comparison.

C and E again fail to indicate the second term of the comparison.

ACE都是than后没有比较对象

In
B, the misuse of modifying phrases produces an ambiguous and awkward statement: even more
gasoline-efficient cars could refer either to more cars that are efficient or to cars that are more efficient.

而b是比较对象有歧义

但b后面也没有比较对象啊,意思是不是b不仅没有比较对象,而且比较对象有歧异那?

如何区分,看以前讨论没有定论

那ace就不是省略比较对象吗?

明白了

非常感谢

感谢你一直回答我的问题,今天又看了一下想在追问一下怎么理解 :A,C,E有补出修饰试图明确修饰对象，但是fail to identify

A，E后面有on the road

C后面有the road

这个就是补出修饰试图明确修饰对象

个人意见！
