一个形容词和副词的修饰题

修饰问题

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

E.      wings, wings having been shaped smoothly and perfectly so

答案是B，但我选了C，觉得perfect也可以用来修饰wings啊。。。。

哦哦！！明白了，平行的问题是吧。。。

呜呜，竟没发现这个。。。。

不过我觉得如果改成wings that are shaped so smooth and so perfect就可以了吧？请教

嗯。。。我觉得perfect用来修饰wings也可以吧？

之前做过一题：

In the traditional Japanese household, most clothing could be packed flat, and so elaborate closet facilities were unnecessary.这里的flat也跳过了packed来修饰clothing，所以我觉得在wings题中，如果C项不出现平行问题，perfect也不用变成副词来修饰shaped吧？

求教

你说的那个例子flat其实是修饰packed的

本题中的smooth和perfectly是一个形容词和一个副词分别修饰shaped

哦。。。明白了，刚查了字典，原来flat也可以是副词哦，谢谢啦！

另附上flatly的用法，以防他人再弄错。

1。flatly refuse/deny/oppose etc something
to say something in a direct and definite way that is not likely to change
He flatly denied ever having met the woman.
2。without showing any emotion
'Aunt Alicia has changed her will,' she said flatly.
