两位美国科学家做过一个有趣的试验:在两个玻璃瓶里分别放进5只苍蝇、5只蜜蜂,然后将瓶底对着亮光,瓶口朝向暗处。几小时后,5只苍蝇从瓶子后端暗处找到出口,爬了出来,5只蜜蜂全都撞死。科学家分析认为,蜜蜂把有光源的地方看作唯一出路,每次都朝同一方向飞,而苍蝇不死盯着那点儿 An interesting experiment was done by two American scientists: put five flies and five bees in two glass jars respectively, then put the bottom of the bottle against the light with the mouth facing the darkness. A few hours later, five flies found their way out of the darkness at the back of the bottle and crawled out, killing all five bees. Scientists believe that bees have the light source as the only way out, fly in the same direction each time, and the flies do not stare at that point
