小故事

Whiskey Does You Good
威士忌对你有好处
A professor of chemistry wanted to teach his class a lesson about the evils of alcohol, so he produced an experiment that involved a glass of water, a glass of whiskey and two worms.
化学老师要给班里的同学们讲解酒的坏处，他用一杯水、一杯威士忌和两只蠕虫做了一个实验。
"Now, class, observe closely the worms," said the professor putting a worm first into the water. The worm in the water writhed about, happy as a worm in water could be.
“同学们，注意观察这两只蠕虫，”老师说着将一只蠕虫放入水杯中。这只虫子如鱼得水般地在水中扭动着。
The second worm, he put into the whiskey. It writhed painfully, and quickly sand to the bottom, dead as a doornail.
老师又把第二只蠕虫放进了威士忌酒杯，它痛苦地扭动着，很快沉到了杯底，死了。
"Now, what lesson can we derive from this experiment?" the professor asked.
“同学们，你们能从这个实验中得出什么结论呢？”老师问道。
Little Johnny, who naturally sits in back, volunteered, "Drink whiskey and you won't get worms!"
从来都是坐在教室后排的小约翰尼主动答道：“喝威士忌就不会长寄生虫！”
