42. The current administration, ［ｕ］being worried over some foreign trade barriers being removed and our exports failing［/ｕ］ to increase as a result of deep cuts in the value of the dollar, has formed a group to study ways to sharpen our competitiveness.
A. being worried over some foreign trade barriers being removed and our exports failing
B. worrying over some foreign trade barriers being removed, also over the failure of our exports
C. worried about the removal of some foreign trade barriers and the failure of our exports
D. in that they were worried about the removal of some foreign trade barriers and also about the failure of our exports
E. because of its worry concerning the removal of some foreign trade barriers, also concerning the failure of our exports
Choice C is best because its phrasing is parallel and concise. A, D, and E begin with unnecessarily wordy phrases. Choice C also uses the idiomatic expression worried about rather than worried over (as in A) or worrying over (as in B); worried about is preferable when describing a condition rather than an action. Whereas C uses compact and parallel noun phrases such as the removal... and the failure ... , the other choices employ phrases that are wordy, awkward, or nonparallel. D is also flawed in that the plural pronoun they does not agree with the singular noun administration.
这道题已被问过好多遍了，我想问的是 worried about 后the removal of some... 和 the failure of .... 应该都是about 的宾语吧，那么为什么不是 worried about A and also about B, 而是worried about A and also B? 这两种形式有何区别吗？
请教
有区别, about A and about B不简洁。
这题的平行结构非常清晰，不需要特意补出about来明确平行的层次结构.
