Now Your Turn
SAMPLE DIALOG¹
A: I’m so glad to be back home, again. Oh, what a clear blue sky!
B: Yes, the wind has cleared the air. I hope you still remember the situation a couple of years age; that is, when you were here. Each spring a big sandstorm² struck our city.
A: Oh, that was bad. That air was filled with sand and dust. I had to wear a scarf around my head.
B: I had to cover my mouth and nose with a handkerchief. And facial³ makes sold well. The dust came from the north, and it often rose after a long dry spell.
A: If the drought⁴ continued, the soil was easily airborne. And when the wind came, the soil was swept up on the cold air, and it could travel very long distances.
B: When the dust was brought in with the wind, we could hardly breathe, we couldn’t see well, and it was dangerous for driving.
A: How did your town solve the problem?
B: Not only our town. In fact, people in the whole province planted a lot of trees and grass so that the soil would stay where it is.
A: I see. The government launched⁵ an afforestation project to deal with the sandstorm. The green shelter⁶ belt is playing a role.
