Divide the whole class into several groups to discuss questions in activity 2. Then call back the answers) S1: Most of the sandstorms begin in desert areas. Because there are no trees and grasses in the desert areas. The wind is very strong. S2: Climate changing can create deserts, but nowadays, the deserts are being enlarged because of humanity. S3: Deserts are also created because people cut down trees and dig up grass. T: Why people cut down trees? S3: They want to get wood or to plant crops. S4: Few years ago, Japan was affected by the sandstorms coming from northwest China. And America is also affected by sandstorms. Some are caused by humanity; some are from Asia blown across the Pacific Ocean. Sandstorm has been a global issue. T: Very good, thank you. Can we prevent it? S5: Yes. At present, our China has carried out many plans to prevent sandstorm. For example, China has formed a professor committee to study how to prevent sandstorms. We have planted many trees every year.
