It was built over 2,200 years ago to solve a water problem: the Minjiang River frequently flooded the area. Instead of building a dam, Li Bing, the governor, divided the river into channels. This controlled the floods and provided water for farming. As a result, farmers could grow more plants. Today, the system still irrigates over 6,600 square kilometres of land. And it became a UNESCO World Heritage site in 2000. The system remains important today. It works well and attracts many tourists every year. Without it, life in this area would be much harder. This project shows how we can work with nature for a better life. It also reflects the great wisdom of the ancient Chinese. We must protect it for the future. 设计意图：提前学习范文的内容、语言、结构，使学生的写作有章可循。 One of the most famous examples of people changing nature is China's South-to-North Water Diversion Project (南水北调工程). This is a system that moves water from the rainy south to the dry north of China. The idea began in the 1950s, and construction (施工) started in 2002. How does it work? There are three main routes (eastern, middle, and western) that use canals, tunnels (隧道), and pipelines (管道) to transfer water over long distances. An amazing fact is that the middle route alone is about 1,432 kilometers long – that's longer than the distance from Beijing to Shanghai! This system provides water for millions of people, helps farms grow crops, and supports factories in northern cities. This project is extremely important because it solves serious water shortages in northern China. It shows how humans can use engineering to balance nature's resources. I believe people will continue such projects in the future to adapt to climate change. However, we must also protect rivers and use water wisely while changing nature. 设计意图：提前学习范文的内容、语言、结构，使学生的写作有章可循。 Step 3 Check.
