考研英语阅读基础练习：经济学中的弹性是什么?

Elasticity is a term used a lot in economics todescribe the way one thing changes in a givenenvironment in response to another variable thathas a changed value.

弹性是经济学中经常使用的一个术语，用来描述在给定环境中一个变量相对于另一个变量发生一定比例改变的属性。

For example, the quantity of a specific product soldeach month changes in response to themanufacturer alters the product's price.

例如，每个月销售的特定产品的数量随着厂商改变产品的价格而变化。

A more abstract way of putting it that means pretty much the same thing is that elasticitymeasures the responsiveness of one variable in a given environment to a change in anothervariable, which in this instance is a change in price.

更为抽象的说法，弹性衡量的是给定环境中一个变量对另一个变量变化的响应性，在这个例子中是价格变化。

Or you could also say it measures "the sensitivity" of that variable.

或者你也可以说它测量了这个变量的“灵敏度”。
