3. 特点三是chimpanzee会hunt 和kill 其他生物来吃肉,而bonobo不会,它们只吃nuts 和plants。
听力要点
【听力】
1. 因为实验室是在控制条件下而非野外环境中进行,所以动物不会表现得像在野外环境中那样。
2. 因为bonobo族群也存在欺负弱小的现象,只不过是在没有别的东西在的时候,研究人员都去观察chimpanzee了所以没有发现。
3. 因为人类行为影响到了chimpanzee的素食来源, 所以它们才去hunt和kill其它动物,当前的bonobo的habitat离人类比较远,所以人类没有影响到它们。如果有一天人类活动影响到了bonobo的habitat,估计bonobo也会因为食物不够而去猎杀其他动物。
