正确答案是B,但是为何C不对呢？想来想去还是不懂！谢谢各位指教！！！

651.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

are shaped后面要用副词修饰动词shaped,并且c中的限制性定语从句不好，这样就表示还有frictionless wings that are not shaped....,要用限制性的从句或分词。原句的意思是用smooth修饰wings,用perfectly修饰shaped,所以答案是B.这题很难，要看懂题意，还有就是smoothly不能修饰perfect.

Smooth and perfect can not be used to modify the verb shape because they are adjectives.
