The first unit of the first volume of the fourth grade primary school published by the People's Education Press: Autumn in my hometown. There are a few white clouds floating leisurely in the blue sky.

On Saturday evening, the sky was overcast, with drizzle falling from time to time.

Several barn swallows were playing carefree on the road.

Suddenly, a large truck roared past. My heart tightened and I couldn't help but close my eyes.

I know something bad happened.

A barn swallow fell in a pool of blood. It looked like a mother, and the little barn swallow next to it was its child.

The little house swallow was very surprised to see her mother like this.

It took a step forward first and looked at the moving truck. Tears fell on its mother's wings.

He was stunned, but he didn't give up hope.
