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.
选项
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
B
解析
The sentence as written is not stated clearly. For example, it is unclear what is shaped so smoothly and perfectly; it could be either the airplanes or the wings. Upon considering the likely intended meaning, along with a review of the other answer choices, it seems most likely that the phrase is intended to modify frictionless wings.
Next, we need to consider whether it makes more sense to say that the wings are smooth or shaped smoothly. This issue can be determined only by considering the most plausible intended meaning rather than by considering just the grammar of the sentence. The idea of being smoothly shaped would seem already to be part of the idea of being shaped perfectly, and therefore it is redundant. On the other hand, having a surface that is very smooth would be crucial in a quest to make an airplane wing frictionless; for this reason, it makes sense to point out that the wings themselves are smooth.
A This choice is incorrect for the reasons stated above.
B Correct. Given the repetition of the word wings, it is clear that what follows modifies wings and not airplanes. Describing the wings as smooth and perfectly shaped clearly conveys what is most likely intended.
C In this version, note that shaped is modified. For this reason, proper grammar requires that the adverbs smoothly and perfectly are needed rather than the adjectives smooth and perfect. However, as discussed previously, the intended meaning of the sentence would be better conveyed if we used the adjective smooth to modify wings rather than the adverb smoothly to modify shaped.
D It is initially unclear what is being described as having been shaped in such a smooth and perfect manner, it could be either the airplane or its wings. Even if that were clarified, however, the sentence would be flawed: the sentence is intended to describe the wings themselves, not the manner in which the wings were shaped. That is, this wording could be interpreted as referring to the nature of the wings themselves or to the process through which they were made. This ambiguity makes the meaning of the sentence unclear.
E This version is very awkwardly worded,
mainly because of having been. Furthermore, this version describes the act of shaping the wings. Because the sentence is instead meant to describe the wings themselves, this choice is incorrect.
The correct answer is B.
