Strong sandstorms attacked these areas every spring. The strong wind blew away the rich soil. Good farmland slowly turned into sandy land, so local villagers had less and less farmland to use. What’s more, these places had little rain all year round and faced serious water resource shortage. It was very hard for farmers to grow crops. Besides, local farmers only used old farming ways. They had no modern tools and farming skills. This shortage of technology stopped them from growing good crops like corn. To change the bad situation, the local government took many useful steps and gave strong support to protect the environment. First, it provided money and free young trees. Local villagers worked together to plant lots of trees and green bushes on the dry hills. The tree roots can hold the soil tightly. Second, the government invited agricultural experts(农学专家) to the villages. The experts taught villagers new and easy farming skills, water-saving methods and modern planting knowledge. With these lessons, farmers learned how to protect farmland and grow crops better. After the hard-working of the government and local people, the environment has changed greatly for the better. Sandstorms are much fewer and lighter than before. Large areas of dry sandy land have become good farmland again. With the help of modern farming and water-saving technology, crops grow well and harvests become richer. Local people no longer worry about bad weather and poor crop output. Their living conditions are becoming better and better. Environmental protection is not an easy and short-term job. It needs long-term effort from everyone in society. We should understand the importance of protecting nature and make our home more beautiful. 1.What natural disaster hit northern villages every spring? ______________________________________________________________________________ 2.Who gave money and young trees to the local villages? ______________________________________________________________________________ 3.What did villagers do to protect the dry hills? ______________________________________________________________________________ 4.Do local people have a better life now?
