考研英语阅读基础练习：经济学中的弹性是什么?

Often, e conomists speak of a demand curve, where the relationship between price and demandvaries depending upon how much or how little one of the two variables is changed.

通常，经济学家说的是需求曲线，即价格和需求之间的关系取决于两个变量中的一个变化了多少。

Some Examples of Elasticity and Inelasticity

弹性和非弹性的一些例子

It's not surprising when a manufacturer substantially increases a product's price, that consumerdemand should diminish.

当制造商大幅度提高产品价格时，消费者的需求就会减少，这不足为奇。

Many common items, such as aspirin, are widely available from any number of sources.

许多常见物品，如阿司匹林，可以从许多来源广泛获得。

In such cases, the product's maker raises the price at its own risk -- if the price rises even alittle, some shoppers might stay loyal to the specific brand -- at one time, Bayer nearly had alock on the U.S. aspirin market -- but many more consumers would probably seek the sameproduct from another manufacturer at the lower price.
