Read and find out:
(1) what problems the local people solved by working with nature
(2) what solutions they came up with
(how many) problems are solved.
The first problem is ……They solved the problem by……
Use the following expressions to answer the question.
Two problems are solved.
The first problem is that there are few large, flat areas of land in the region for people to grow rice. They solved the problem by increasing the areas in which they could grow rice.
The other problem is that the mountains are steep and the soil is shallow. This problem is solved by letting the flat terraces catch the rain water and prevent the soil from being washed away.
Para 3:the reasons to build terraces—— why
Para 3:the reasons to build terraces—— why
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 in 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.
Para 4:the working principle —— how
Analyze several steps of Longji Rice Terraces’ working principle and complete the picture.

Write a short summary according to the structure and theme.
Think & Share
In what other ways do people live in harmony with nature Give examples.
The Longji Rice Terraces were built by the local Zhuang ethnic group alone.
Though there are many large, flat areas in the region, they built terraces on the mountains to have more areas to grow rice. The terraces are cleverly designed, and can wash away the shallow soil. There are hundreds of waterways, along which rainwater moves down the mountains and into the terraces. Today, local people use
modern methods to maintain the terraces, and they attract lots of visitors from all over the country.
Correct four factual mistakes. Then, compare your summary with the one of Activity 4 on page 85.
