这题目是一位编辑给我出的，很有意思--看起来简单，却不容易答得出来。即便东拉西扯勉强应付一通，其答案也会五花’＼fi。商品经济时代，似乎连幼儿园的孩子都知道商品交换。我们曾经有过“全民皆兵”的年代，现在差不多是“全民皆商”的时代。商品意识就是时代意识，人人都能大谈 This topic was given to me by an editor. It was very interesting - it looked simple but it was not easy to answer. Even if East Lasi pulls on a coup, the answer will be ’fi’. In the era of commodity economy, it seems that even kindergarten children know the exchange of goods. We used to have an era of “all people are fighting” and it is now almost an era of “all people are business”. Commodity awareness is the awareness of the times and everyone can talk about it.
