Reading Comprehension - All from old JJ

在4－6题，40多行
第一段说很多culture organization经费紧张，让后列举了些事实

老客户的忠诚度
老观点认为老客户好.因为老客户用比较少的成本(用了一个词来表示企业为得到客户所花的费用,我不记得了).不过呢, 好像实际情况不是这样的.老客户不必新客户花的少.一个survey发现,被survey的四个公司,老客户都不比新客户花的少. Hi-tech公司老客户花的比新客户花的最多.mail-service公司也是. survey还发现,老客户比较喜欢通过电话改变购买主意.这对公司降低客户成本有好处. 然后又说,其实因为电话成本高了,最后算下来,老客户花的也不比新客户少.通过Web莱改变购买东西比较省钱,所以,Web方式老客户应该最省钱.
q:Hi-tech为什么老客户花钱多?
q:mail-service怎样最省钱.
