The companies that Dr. Curtis turned to -Procter & Gamble, Colgate-Palmolive and Unilever -had invested hundreds of millions of dollars finding the subtle cues in consumer’ lives that corporations could use to introduce new routines. (2010英语二text3)
【单词解析】subtle：adj. 微妙的;corporation：n. 大型公司;routine：n. 日常惯例;turn to(求助于);invest … doing sth. (投入……做某事);introduce new routine (引进新惯例)
【主干识别】The companies had invested hundreds of millions of dollars finding the subtle cues.
【其他成分】that Dr. Curtis turned to -Procter & Gamble, Colgate-Palmolive and Unilever 是由that引导的定语从句，修饰companies，双破折号里的内容解释说明有哪些companies，这里边的内容在考试中可以先不用看;finding the subtle cues in consumer’ lives that corporations could use to introduce new routines. 现在分词短语做状语修饰动词invest，后边还跟了一个that引导的定语从句修饰subtle cues，其中corporations做主语，could use是宾语，that 代替先行词做宾语，to introduce new routines是目的状语。
【整体分析】整句话难度不算太大，关键点在于主干结构谓语的识别，只要主干结构识别清楚，整句话就很好理解了。
【参考译文】柯提斯博士求助的公司有宝洁、高露洁和联合利华，这些公司曾投资几亿美元用于发掘消费者生活中的微妙暗示，并利用它们引入新惯例。
【翻译点拨】将第一个that定语从句前置，其他内容顺译即可。
