Firstly, by playing the documentary "Talking about the Yangtze River", students are guided to understand the relationship between humans and nature, discuss the contribution of the Yangtze River to the Chinese nation, the damage caused by humans to the Yangtze River ecology, and protection measures. Next, by analyzing the "London Killer Fog Incident" in the UK, students will gain insight into human wisdom and explore how to achieve harmonious coexistence between humans and nature. Then, taking the green development practice in Yucun, Anji County, Zhejiang Province as an example, let students understand the laws and regulations formulated by China in building ecological civilization, and explore how to walk the path of green development well. Finally, guide students to depict the "beautiful China of the times" in their minds and explore what can be done in daily life to jointly build a beautiful China. The entire teaching process aims to make students realize that the construction of a beautiful China requires the country to formulate correct policies and guidelines, and citizens to take active and conscious actions, thereby stimulating students' sense of social responsibility and cultivating their ability to participate in social public affairs.
