(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
Answer B. I think it should be C. "He made his art work so beatufiul" rather than "He made his art work so beatufiully" So "smooth" and "perfect" are to qualify "wings", rather than "shape"
我觉得有2个原因: 1、这里用smoothly和perfetly修饰SHAPED是没有错的,反而wings are shaped so smooth and perfect that是有问题的,除非改成,Smooth and perfect,wings are shaped by....
2、同时对C的时态也表示怀疑,因为看未划线部分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。后半部分这明显是个虚拟语气,即还没有实现的梦想,所以那个are 感觉上是有问题的。而A回避了这个问题。
C. 副词修饰shaped --- are shaped so smoothly and perfectly. in B) wings, wings so smooth and so perfectly shaped smooth 修饰 noun wings, and perfectly 修饰 shaped.
以下是引用joice在2003-9-21 22:34:00的发言: C. 副词修饰shaped --- are shaped so smoothly and perfectly. in B) wings, wings so smooth and so perfectly shaped smooth 修饰 noun wings, and perfectly 修饰 shaped.
I meant : (C) wings that are shaped so smooth and perfect 1.shaped so smoothly and perfectly is correct, but shaped so smooth and perfect is not. 2. ' that' refers to airplans or wings ? it is ambguous.
B) wings, wings so smooth and so perfectly shaped B doesn't have this problem. smooth modifies wings and perfectly modifies shaped.
