的。这意味着我们要返回前一天晚上我们离开时黑猩猩一家睡觉的大树旁。大家坐在树荫下等待着，这时候猩猩们睡醒了，准备离开。然后这群黑猩猩向森林深处漫步而去，我们尾随其后。在大部分时间里，黑猩猩或互相喂食，或彼此擦身，这在它们的家族里是表达爱的方式。简预先提醒我们，到下午的时候我们就会又累又脏，她说对了。不过到傍晚时分我们觉得这一切都是值得的。我们看到黑猩猩妈妈跟她的幼子们在树上玩耍，后来看见它们一起回窝里睡觉了。我们认识到黑猩猩家庭成员之间的关系像人类家庭一样紧密。

　　Nobody before Jane fully understood chimp behaviour. She spent years observing⑬ and recording their daily activities. Since her childhood⑭ she had wanted to work with animals in their own environment. However, this was not easy. When she first arrived in Gombe in 1960, it was unusual for a woman to live in the forest⑮. Only after her mother came to help her for the first few months was she allowed to begin her project⑯. Her work changed the way people think about chimps⑰. For example, one important thing she discovered⑱ was that chimps hunt and eat meat. Until then everyone had thought chimps ate only fruit and nuts. She actually observed chimps as a group hunting a monkey and then eating it⑲. She also discovered how chimps communicate with each other, and her study of their body language helped her work out⑳ their social system.
