美国人索尔·贝娄小时候捉到一只小画眉放到笼子里,开始时那只小鸟不安地拍打着翅膀,后来就安静下来了。第二天,他发现有一只成年的画眉在专心致志地一口口喂小画眉梅子,当时他很高兴。可是次日,小画眉竟死了。鸟类学家解释说:“当一只画眉发现它的孩子被关在笼子里之后,就一定要喂小画眉足以致死的毒梅。它坚信:孩子死了总比活着被剥夺自由和快乐好些。” American Saul Bellow childhood caught a small thrush into the cage, the bird began to flap her wings uneasily, then quiet. The next day, he was glad to find that an adult thrush eagerly fed his little thrush plum. But the next day, a small thrush actually died. Ornithologists explain: “When a thrush discovers that its child is in a cage, be sure to feed the thrush enough to kill the poison plum. It firmly believes that children die more than being deprived of their liberty and happiness Better. ”
