VI. Furthering Listening and Speaking
Task 1: Dust Storms
American researchers say dust clouds from dry African deserts may be a threat¹ to human health in the United² States. The dust may contain many small organisms³ that could be dangerous. Each year, huge storms form in the Sahara desert of northern Africa. Winds carry the dust across the Atlantic Ocean. The movement of dust has been increasing in recent years because of longer periods settles⁴ in South America. From June to October, the winds change and transport the dust to North America, Central America and the Caribbean. More than half of the dust that reaches the United States settles in the sate⁵ of Florida. For many years, it has caused the skies there to turn red. There is probably a link between the dust storms and higher rates of allergies⁶ and breathing problems in people in this area.
