Some actors and rock stars use their star power for social activism. But how much power do they really have? Daniel *Drezner is a professor of international politics at the Fletcher* School at Turts* University in Massachusetts. He said measuring the effects of celebrity activism can be difficult.

一些演员和摇滚歌星利用自己的明星效益做社会活动。但是，他们真正的能力有多大呢？Daniel Drezner是塔夫斯大学佛莱契学院国际政治的教授。他说，计算明星行动主义的效应是困难的。

He thinks perhaps the most successful example is Princess Diana’s campaign against landmines in the 1990s. Yet, in the end, he says, it was hurt death in a car crash that brought more attention to her work and to the issue.

他认为，也许最成功的例子就是戴安娜王妃90年代组织的反对地雷活动。然而，他说，最终因王妃死于车祸而使人们更关注她的工作和这个问题。

Professor *Drezner says celebrity activism can have influence. Star power can bring public attention, donations and pressure for action on important issues. It also can educate fans through stories in the entertainment media.

Drezner教授说名人行动主义会产生一定的影响。明星效应可以引起公众注意，筹集捐款并且在较重要问题的行动中施压。他们还可以通过娱乐媒体中的故事教育他们的粉丝。

But at same time, there are risks. Most people will grow tired of an issue, the professor says. And they might also grow tired of the (a) celebrity who keeps talking about it, especially if they thinking governments already are taking action. Also, when star power is directly at one crisis, others could be forgotten.

但是，同时，也是存在危险的。教授说，多数人会对一个问题产生厌烦。而且，如果明星不断的谈论这个问题，尤其是当人们认识政府已经插足此事时，他们也会感到厌倦。 当明星处于低谷期的时候，其他人也可能忘记。
