1)推断文章内容的含义和引申意思
From Paragraph 4 we can infer that .
[A] the increasing concentration is certain to hurt consumers
[B] WorldCom serves as a good example of both benefits and costs
[C] the costs of the globalization process are enormous
[D] the Standard Oil Trust might have threatened competition
命题者设置的难点是第二句中定语从句的理解。原文谈到“目前难以预料,数家石油公司的合并是否会再次对竞争造成威胁。100年前美国的标准石油联合公司(Standard Oil Trust)被解散,就是因为当时人们担心它会对竞争构成威胁”,由此引申推理可知[D]项“标准石油联合公司可能曾对竞争形成过威胁”。此外,考生还需要注意,might have threatened是虚拟语气,表示对过去的推测。
