怎么AA001的数据库出现错误呢 难道被删除了？ 请斑竹解答 因我正有问题：（先粘在这吧，强人帮我解答一下） 1、The following appeared as part of an annual report sent to stockholders by Olympic Foods, a processor of frozen foods.
“Over time, the costs of processing go down because as organizations learn how to do things better, they become more efficient. In color film processing, for example, the cost of a 3-by-5-inch print ？fell from 50 cents for five-day service in 1970 to 20 cents for one-day service in 1984？. The same principle applies to the processing of food. And since Olympic Foods will soon celebrate its twenty-fifth birthday, we can expect that our long experience will enable us to minimize costs and thus maximize profits.” 当中“成本从五天50分降到每天20分”，这句话是由逻辑问题吧，作一简单除法后发现不是成本降低反而应该是升吧 。不知道我的理解是否正确，一直不敢肯定题目当中会否有这么低级的错误，还是我理解错误。 牛人帮下忙哈 先谢了  |
