Dr. Jane Goodall and the chimps It is 5:45 am and the sun is just rising over Gombe National Park in East Africa. Following Jane‘s way of studying chimps, our group are all going to visit them in the forest.

Until then (then指代的是什么时候,从哪儿判断出来)everyone had thought chimps ate only fruit and nuts. She actually observed chimps as a group hunting a monkey and then eating it.
