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
in research for developing cars that are even more gasoline-efficient than presently on the road
答案选D
问题1：但我觉得D 改变了原句even的位置。原句even than presently on the road 甚至比现在的车还好，强调现在的车。D中even more gasoline-efficient 强调更省油
问题2： lzm语法中说than 和 as 后有时可省略主语（参见og187)。不知112中A选项能不能算是这种省略形式
