曾有人做过实验,将一条凶猛的鲨鱼和一群热带鱼放在一个用强化玻璃隔开的池子里。最初,鲨鱼每天不断冲撞那块玻璃,可它始终不能游到对面去。实验人员每天都放一些鲫鱼在池子里,所以鲨鱼并不缺少猎物,只是它仍想游到对面去,想尝试那新鲜的滋味,因此,鲨鱼每天仍不断的冲撞那块玻 Someone had experimented with placing a ferocious shark and a pack of tropical fish in a pool of tempered glass. Initially, the shark constantly collided with the glass every day, but it could never swim across. The experimenter put some crucian carp in the pond every day, so the shark did not lack the prey, but it still wanted to swim across to try the fresh taste. Therefore, the shark continued to collide with the glass every day
