GMAT写作素材之对破坏环境行为的处罚的三种作用

　　段落大意： 虽然有许多禁止污染的法律法规， 但是污染行为仍屡见不鲜。处罚的三种作用： 赔偿、 惩罚和预防。

　　Though there are many laws restricting pollution, there are still polluters. The primary goal of pollution control laws is to protect human health. The one thing all pollution control methods share are penalties imposed on violators of environmental laws and regulations. Penalties usually serve three functions: restitution, retribution, and deterrence. Restitution, usually through compensation, serves to cover any damage caused by the violation. Retribution is the penalty imposed for the violation itself, while deterrence is meant to prevent future violations.
