Mama says all the dust is due to the drought. The dirt sifts into everything. It covers our clothes. We have to wash the dishes before each meal. We rarely drive the truck because Papa fears the dust from the road will ruin the motor.When my sister, Faye, and I walk to school, we wear kerchiefs over our mouths so we dont breathe in the dirt. On days when the air is so bad that they close the school, we stay home and help Mama put wet sheets over the windows. But the dirt always finds a way in.Last Sunday, there was no dirt in the air, only bright spring sunshine and a clear blue sky. After lunch, Papa headed out to the field to check on the cattle while I played with Faye in the yard. The temperature suddenly dropped. I looked to the west and saw a huge black cloud of dust. All the birds flew away. “I must warn Papa,” I thought to myself. To avoid her panicking, I gently told Faye to go back inside where she would be safe, and then headed off to the field.英语试题 第 11 页 共 10 页The storm hit so fast, and in an instant the day turned into night.

He then pulled me into his arms and said, “Oh, Iris, you saved me!”Finally, the wind subsided and the dust began to settle. Dirt was piled up to the window on one side of the truck and halfway up the door on the other. Papa kicked against the door, opening it far enough to let us out.Sand and soil drifts were everywhere, but we were safe.21. What is the main function of the first two paragraphs?A.
