曾经听生物老师讲过一个美国教授做的实验:把几只蜜蜂放进一个平放的瓶子中,瓶底向着有光的一方,瓶口敞开。蜜蜂们都是向着光亮处不断飞动,却又不断撞在瓶壁上。最后,它们似乎都明白自己永远也飞不出这个瓶子,谁也不再尝试,个个奄奄一息地落在瓶底。教授把这些蜜蜂倒出来,把瓶子按原样放好,再放入几只苍蝇。苍蝇和蜜蜂不一样,它们除了向有光亮处飞动外 Once heard a biological teacher talked about the experiment done by a professor in the United States: put a few bees into a flat bottle, the bottle toward the shiny side, the bottle open. The bees are constantly moving toward the light, but constantly hit the bottle wall. In the end, they all seemed to understand that they could never fly out of the bottle, and no one tried it any longer and dying on the bottom of the bottle. The professor poured the bees out, put the bottle as it was and added a few more flies. Flies and bees are different, except that they fly to the bright place
