词汇:society 社会 As well as impressive physical attributes, elephants have a rich cultural heritage, passed down through customs and social behaviour which is learned, remembered, and shared within their herds. This is possible partly because of their social structure. Elephants live in complex, tightly knit, multigenerational societies, led by older females known as matriarchs. Younger elephants observe and mimic the behaviour of their elders, learning through experience. It helps that the herd does almost everything together, from foraging and feeding to raising each others' young. These interactions lead to deep long-lasting relationships, which can last for decades. Possibly because of these bonds, elephants seem to have emotional capacity. Just like humans, the creatures have been seen displaying signs of grief. When an elephant dies, others in the herd have been observed to repeatedly return to where the individual passed, which is said to be part of a mourning ritual. They may sniff and touch the carcass and bones and cover the site with leaves and sand. Moreover, a 2020 study by researchers Goldenberg and Wittemyer found that "elephants show broad interest in their dead regardless of the strength of former relationships with the dead individual", which may indicate advanced sentience, the scientists say. There's a saying found in many languages – 'an elephant never forgets'. In fact, memory has been essential to the survival of some elephant herds. A study within Great Kruger National Park found that, during an extreme drought in 2016, elephant groups led by matriarchs who had previously lived through a severe drought, had higher survival rates. Researchers concluded that the matriarchs likely remembered where sources of water could be located. So, count yourself lucky that you live on the same planet as these immense majestic animals. 词汇表physical attribute 身体特征 测验与练习1. 阅读课文并回答问题。 1. What is the social structure of elephant societies? 2.
