　　Its strategy rests on two beliefs: first, a global product offers economies of scale with which local brands cannot compete, and second, consumers in the 21st century are drawn to "global" as a concept. (06.1 Passage 1)
　　主干：Its strategy rests (on...)

　　译文：公司的策略基于两个信念：首先，全球性的产品能够提供地方品牌无法与之竞争的规模经济；其次，21世纪的消费者认可“全球”这个概念。
