关于 cost 的表达,从属关系用 to,属性关系用 of, 所以美国能源业迎合规定的成本的最优表达是 cost of meeting environmental regulations to the United States petroleum industry。次优表达是 cost to the United States petroleum industry of meeting envrionmental regulations 关键是 to 和 of 的使用,可以参见大全以下例子 110. It has been estimated that the annual cost to the United States of illiteracy in lost industrial output and tax revenues is at least $20 billion a year. (A) the annual cost to the United States of illiteracy in lost industrial output and tax revenues is at least $20 billion a year (B) the annual cost of illiteracy to the United States is at least $20 billion a year because of lost industrial output and tax revenues (C) illiteracy costs the United States at least $20 billion a year in lost industrial output and tax revenues (D) $20 billion a year in lost industrial output and tax revenues is the annual cost to the United States of illiteracy(C) (E) lost industrial output and tax revenues cost the United States at least $20 billion a year because of illiteracy In choices A, B, and D, the combined use of annual and a year is redundant. Choices A, D, and E are awkward and confused because other constructions intrude within the phrase cost... of illiteracy: for greatest clarity, cost should be followed immediately by a phrase (e.g., of illiteracy ) that identifies the nature of the cost. Choice E is particularly garbled in reversing cause and effect, saying that it is lost output and revenues rather than illiteracy that costs the United States over $20 billion a year. Choice B is wordy and awkward, and idiom requires in rather than because of to introduce a phrase identifying the constituents of the $20 billion loss. Concise, logically worded, and idiomatic, choice C is best. 而且 A C D E 中时间状语 by the end of the decade 都错误修饰了 estimated 或者 projected,都是典型的错误 因此,本题只能选 B 可恨,做题的时候怎么就没看出来……
