文档介绍：极端天气?
Sand storms have hit much of northern China, leaving many places including Beijing shrouded in thick yellow dust. With people forced to cover their faces against the dust, the authorities have warned residents to stay indoors. Deserts now covered a third of China and that spread has been blamed in part in deforestation and the spread of cities.
