What other films or books do you know that feature wild animals? Do they “paint” a good or bad picture of these animals? Say how the animals are described. Take The Call of the Wild , for example. In Jack London's novel The Call of the Wild, wild animals are described in the novel as good animals, and they are given equal importance to the main characters. Through the behavior and characteristics of animals, the author shows their bravery, wisdom and gratitude. When it comes to the relationship between humans and animals: 1. Embodies the harmonious coexistence between humans and animals. 2. It embodies the author's idea of equality between humans and animals. In The Call of the Wild, the author expresses respect and care for animals through vivid description and deep thinking, and criticizes the anthropocentrism and the destruction of nature. 就拿《野性的呼唤》为例吧。在杰克·伦敦的小说《野性的呼唤》中，野生动物在小说中被描述为好的动物，它们与主要人物处于同等重要的地位。作者通过动物的行为和特性，展示了它们的勇敢、智慧和感恩之心。说到人类与动物的关系 ：1.体现了人与动物之间的和谐相处。2.体现了作者倡导的人与动物平等的观点。在《野性的呼唤》中，作者通过生动的描写和深入的思考，表达了对动物尊重和关爱的同时，也对人类中心主义和对自然的破坏行为提出了批判。 33002 Thinking Time According to this passage, we have learned that due to people's hunting, sharks are in danger of extinction.
