One term lefts to
explain, that is demand. When human want backed by buying power then it becomes
demand. For example, a staffed animal at a cost of $10-20 is very high amount
according to a third world country (i.e. Bangladesh) value of currency. So,
it children of those country hardly afford this kind of staffed animal. But in USA, almost
every child can buy those products at those price tag. So, we will say that,
third world country’s kids may have need for those toys but not demand and USA childrenhave both.
有一种说法有待于解释,那就是需求。当人希望得到购买力的支持时,它就成为需求。比如,按照第三世界国家(如孟加拉国)的币值,一头价值为 $10-20 的配售动物玩偶是一个非常高的金额,因此这些国家的孩子们几乎买不起这种玩偶。但是在美国,几乎每一个儿童都能以这一标价购买这种产品。因此我们会说,第三世界国家的小孩子也许对这种玩偶有过需要但并不需求,而美国儿童则既需要也需求。
注:
need for 对..有需要的想法
demand 迫切需要
price tag 价格标签/标价
