Grandpa: There used to be sandstorms all the time, and the fields were getting smaller and smaller. Then, after one big sandstorm, we decided to do something. Bob: What did you do? Grandpa: We found a small bush. It had long roots that could hold the soil together. We began planting it in sandy areas. The government provided support too. Bob: Wasn’t it difficult to plant so many bushes? Grandpa: Yes, it was. At the beginning, we worked by hand. Later, we had machines to help. We have planted many bushes and trees since then. There are fewer sandstorms now and the environment is getting better. It has also improved our lives. Everyone has become richer and happier. Discuss how the problems in 2b were solved. Sandstorms → They found a bush whose roots could hold the soil together. Farmland shortage → They planted the bush in sandy fields with the government's support. Difficult environment → Everyone worked together and the land has become green. 2d What can we learn from the changes in Liu Rui’s grandpa’s hometown? Every big change starts with a small step.
