A.
We cannot know for certain if African elephants know that they're under attack, and that we're wiping them out across the continent. There are few, if any, survivors from most poaching events, and those that do ___1___it can't tell us of what they have experienced. We'll ___2___ know what elephants may have witnessed or heard in the ___3___ while their friends and relatives in other families were being___4___.
We have some idea, though, ___5___ in South Africa in the late 20th century, wildlife officials authorized the killing of entire elephant families in some fenced parks, such as Kruger. The officials ___6___ that if a fenced elephant population grew too large, the animals would consume all the vegetation,___7___ they killed the elephants. ___8___, other elephant families in the park knew this was ___9___. Perhaps it was the cries of ___10___ as the animals were shot. Or perhaps those being killed were able to make low sounds that carried the news for miles.___11___ after a killing,and even after rangers(园林管理员)___12___ the area, removing all the bodies, other elephant families would come to the ___13___. They inspected the ground and ___14___ the earth, and then the visiting elephants left, never to ___15___. Observers say that even when the area where a killing took place was ___16___ habitat for elephants, the animals chose not to live there.
What happens now where poachers kill elephant families and herds? Do the animals, filled with empathy(同情)for what the others___17___, come to investigate the killing fields? Do they ___18___ those awful areas forever? Those ___19___ have yet to be made. But in the meantime, can we put our empathy to use in finding a way to ___20___ the elephants? Can we put an end at last to the poaching?
