     Once upon a time, two young men were spending some time in the country. One day, while taking a walk

together, they crossed a large field.

     "Look out!" one of the young men shouted, because a bull (公牛) suddenly appeared and began to chase

(追逐) them. They were very frightened. They ran as fast as they could, but the bull kept chasing them.

     Finally, one of the men climbed up a tree. The other one jumped into a hole, but soon he came out of it.

Immediately the bull chased him back into the hole.

     "Stay there!" his friend shouted, but soon the man came out again, and again the bull chased him right back.

This went on five or six more times.

a while, otherwise (否则, 不然), this bull will keep us here all day!"

某公司想了解一下其产品的需求情况，为此他们组织了一次市场调研活动。按照调研计划，该企业首先进行了一次问卷调查，他们选取了北京、上海两个城市作为代表城市。在这两个城市中，确定这次市场调查的样本数为10000个，并通过间接渠道搜集了有关产品消费者的数据资料，并据此将其分为VIP消费者1000个，高级消费者3000个，普通消费者6000个。他们向消费者所提供的问卷中，问答项目这几百个，而且十分具体。该调查所获得的数据被存入计算机，进行详细的分析。

此外，该公司为了改进其刚刚研制成功的产品，还邀请消费者在产品的销售地试用这种新的产品，并且对新产品进行评价，从他们那里收集各种各样改进的意见。该公司担心消费者有时不能提供准确的信息，因此，市场调查人员经常亲自逛市场，“偷听”消费者购买时的对话，或者干脆装扮成消费者，四处探听店员和顾客对产品的意见。

在亲自获取市场信息的同时，该公司还把其他部门所提供的市场分析进行加工和整理，用以补充市场调查所获取信息的不足。这些从公开出版物、报纸、杂志、政府和有关行业获取的统计资料，为该企业了解整个市场的宏观信息提供了帮助。

来自消费者的信息成千上万，如何分析研究，取其精华，谊公司有其独特的方法。他们把所有信息分为两类，一类是期望值高的信息，即希望商品达到某种程度，或希望出现某种新产品：另一类是具体的改进建议。该公司十分重视前者，这类信息虽然没有具体意见，甚至很模糊，却反映了消费者的期望，是新产品开发的重要启示，而具体的改进意见一旦和高期望值信息结合起来，则能起到锦上添花的作用。
