sec13-07,分词修饰和意思?

7.     Since the 1930’s 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.

(A) wings, shaped so smoothly and perfectly

(B) wings, wings so smooth and so perfectly shaped

(C) wings that are shaped so smooth and perfect

(D) wings, shaped in such a smooth and perfect manner（B）

(E) wings, wings having been shaped smoothly and perfectly so

A为什么不对? 讨论说shaped有修饰airplanes嫌疑. 可我记得OG上有题就是:  

, Ved的形式,解释中说修饰前面词. 依据这原则,这里修饰wings挺好呀?

还有意思的问题, shaped so smoothly 怎么就不对了呢?我觉得合逻辑咧...

wings so smooth and so perfectly shaped:  这个看起来都不怎么平行呀!!!

能这样做吗？楼主，好象，分词必须是伴随的吧！

这个满奇怪的．我也没有特成熟的想法，再看看！

顺便问一句，你这是大全的题目吗

？
