It's too hot.

1, the weather is sultry, there is no wind, and the thick air seems to be frozen. 2. The clods on the ground are boiling hot, and several dark brown crickets jump around like springs. 4. The scorching sun is in the sky, and on both sides of the road, mature grains are bent down by the sun. Grasshoppers are as numerous as grass leaves, making a weak and noisy sound in wheat fields and rye fields and among the reeds on the shore.
