Since the 1930s aircraft manufacturers have tried to build airplanes with frictionless wings, shaped so smoothly and perfectly that the air passing over them would not become turbulent.
wings, shaped so smoothly and perfectly
wings, wings so smooth and so perfectly shaped
wings that are shaped so smooth and perfect
wings, shaped in such a smooth and perfect manner
wings, wings having been shaped smoothly and perfectly so
Here the absolute phrase starting with "shaped" needs to clearly identify what is shaped...wings are shaped OR airplanes are shaped. Only B and E fit that criterion. It wouldn't be hard to eliminate E.
小姐姐的分析都是自己分析的吗 感觉每道题都特别有道理!
我看官方解释然后引用
这部分题是有官方解释的吗 一直没看到呢
明白了,就是导致了歧义 所以要指出是wings
GMAT更偏向选使用同位语的选项
