猫捕鼠,马避敌,河狸筑窝,百鸟歌唱,动物的这些本领是生来就有的吗?不,这是它们父母教育的结果。小鸟在出生两个月后才开始放声歌唱,而在这之前,它必须经常聆听大鸟的歌声,并进行一段时间的唱歌练习。从小离开父母、由人工单独喂养的小鸟,是成不了“歌手”的。它们虽然天生就有发声能力,却只能发出几种单调的声音。 Do cats catch rats, horses evade enemies, beavers build nests, and birds sing. Are these animal skills born? No, this is the result of their parental education. Only two months after birth, the bird began to sing and sing. Before that, it must listen to the bird song frequently and perform singing practice for a while. Children who have left their parents since childhood and are individually fed by humans cannot become “singers”. Although they are naturally capable of sounding, they can only issue several monotonous sounds.
