vibrate使震动，conscience良心
【笑话原文】
The Advantage of Noise
Wherever I drove my old car over 55 miles per hour, it vibrated terribly, so I decided to sell it. My first customer wanted to buy the car, and I battled with my conscience over whether or not to tell him of the vehicle's problem. Finally I did the right thing. Expecting him to drop the deal, I was surprised by his reply.
“That's okay,” he said. “I'm buying this car for my daughter. If she complains about a vibration, I'll know she's driving too fast.”
【中文译文】
噪音的优点
每当我驾驶我那辆旧车时速超过55英里时，它就剧烈地震动起来，所以我决定卖掉它。我的第一位买主想买这辆车。围绕是否告诉他这辆车的问题，我经历了一番与良心的较量。终于我做对了。 我想他会放弃这个交易，却对他的回答吃了一惊。 “那没什么，”他说，“我是给我女儿买这车的。如果她抱怨震动的话，那我就知道她开得太快了。”
