　　9月16日托福听力机经预测之加试题

　　去除咖啡因(lecture)

　　关于咖啡怎样被 decaffeinated(脱去咖啡因)而不破坏原来味道，然后包装。有一个图。讲 gas 怎样在高温高压下 XX(忘了这个物理名词)。decaffeinate 就是这个原理。咖啡豆经过这个过程到一个罐，然后又经过另一物理过程，就 crystalize(明确)了，可以包装了。

　　题目：

　　1) Main topic

　　2) What is the theory the process uses

　　3) Describe the process in the order of happening

　　营销中的 4M 理论(lecture)

　　营销里面的 4M (money media market message) market 注重定位，抓住潜在顾客和市场 media，包括 TV 和杂志 EG：针对年轻老师的产品就应该在年轻老师喜欢看的杂志上做告，举了一个和 teach 有关的杂志名，还有又说了另一个和 teach 相关的杂志，老师不喜欢，就算了。money 和健康有关的产品 在假期之前做广告实惠 message soup 的例子。
