人类的孩子会在妈妈身体里待上9个月,然后才来到外面的世界。黑猩猩的孩子出生前也要在妈妈身体里待上9个月。刚出生的人类小孩会呼吸,会吮吸妈妈的奶。他们还会睁开眼睛,会哭,会打嗝,会打喷嚏,会咳嗽,会撒尿,会拉便便,也会睡觉。但他们不会照顾自己。而刚出生的黑猩猩小孩也是这个样子。 Human children will spend nine months in their mother’s body before they come to the outside world. Chimpanzee children have to stay in their mothers for nine months before they are born. A new born human child will breathe and will suck on her mother’s milk. They will also open their eyes, cry, hiccups, sneeze, cough, pee, and they will go to bed and sleep. But they will not take care of themselves. Newborn chimpanzee children are like this.
