Exposition Details Significance Topic Who? Where? When? Why did they build it? How does it work? Longji Rice Terraces Para 1 Para 2-4 Para 5 mean a lot great wonder Who? Where? When? These terraces were built by the local Zhuang and Yao people, to whom Guangxi is home. Starting in the Yuan Dynasty, work on the terraces took hundreds of years, until its completion in the early Qing Dynasty. Reaching as far as the eye can see, these terraces cover tall mountains, often from the bottom to the very top. Why did they built it? So why did these people go to so much trouble to turn the entire mountains into terraces? Firstly, there are few large, flat areas of land in the region. Building the terraces, therefore, meant that they could increase the areas which they could grow rice. Secondly, although the region has plenty of rain, the mountains are steep and the soil is shallow. The flat terraces catch the rainwater and prevent the soil from being washed away. Topic sentence problem 1 how terraces could help problem 2 how terraces could help How does it work? But perhaps what is most significant is the way in which people have worked in harmony with nature to make these terraces and grow rice. The terraces are cleverly designed, with hundreds of waterways that connect with each other. During the rainy season, it is along these waterways that rainwater moves down the mountains and into the terraces. The sun heats the water and turns it into vapour. This forms clouds from which rain falls down onto the mountain terraces once again. These terraces also provide a perfect environment for birds and fish, some of which feed on insects that can harm the rice crops. Topic sentence ① ① ② ② ③ ③ How does it work? Significance Although modern technology could help produce more crops, these terraces still mean a lot to the local people for whom traditions hold much value. This Knowledge is passed down through families, which means that new generations continue to use ancient methods of agriculture to maintain the terraces. Today, the Longji Rice Terraces attract thousands of visitors who come to admire this great wonder created by people and nature working together. Why do the local people still keep their traditional way of growing rice？ Because for them traditions are so valuable that the knowledge is passed down through generations of families. Besides, the traditional methods suits the natural environment and people can work in harmony with nature. What are the similarities between 'the Floating City' and the Longji Rice Terraces? Therefore, what should we do to live in harmony with nature? We should adapt to local conditions(因地制宜) and make use of nature in an environmentally-friendly way.
