There are several reasons to believe that the urges to help，inform and share are not taught，but naturally possessed in young children.One is that these instincts appear at a very young age before most parents have started to train their children to behave socially.Another

　　is

　　that the helping behaviors

　　are not improved if the children are rewarded.A third reason is that social intelligence develops in children before their general cognitive(认知的)skills，at least when compared with chimps.In tests conducted by Tomasello，the human children did no better than the chimps on the physical world tests but were considerably better at understanding the social world.

　　The core of what childrens minds have and chimps? don?t is what Tomaseuo calls shared intentionality.Part of this ability is that they can infer what others know or are thinking.But beyond that，even very young children want to be part of a shared purpose.They actively seek to be part of a “we”，a group that intends to work toward a shared goal.

　　【语篇导读】　本文是一篇科技说明文。主要介绍的是通过实验对比了黑猩猩与人类在相互帮助的本能方面的巨大不同。黑猩猩没有相互帮助的本能，根本就不懂合作，而人却从小就知道帮助他人，善于与他人合作，这是人类独有的天性。
