美国康奈尔大学的威克教授做过一个实验,把几只蜜蜂放进一个平放的瓶中,瓶底向光;蜜蜂们向着光亮不断碰壁,最后停在光亮的一面,奄奄一息,然后在瓶子里换上几只苍蝇,不到几分钟,所有的苍蝇都飞出去了。 Professor Wick at Cornell University in the United States conducted an experiment in which a few bees were placed in a flat bottle and the bottom of the bottle turned to the light. Bees shouted toward the light and finally stopped on the bright side, dying and then at Change a few flies in the bottle, within a few minutes, all flies fly out.
