The full text *** 9 natural paragraphs, mainly from the three phenomena of "swallows flying low, fish swimming on the water and ants moving", tells the characteristics of some small animals' activities before it rains and the reasons for these phenomena.

According to the content, the paper also has corresponding illustrations. Students can read stories by matching pictures and words, and know that they can understand the weather changes by observing some wonderful phenomena in nature.

When it's going to rain, it's sultry, and some small flying insects fly very low in the sky, with small water droplets on their wings. Swallows fly very low in order to prey on these small flying insects. In addition, when it is about to rain, the airflow in the air is turbulent, and swallows always fly up and down. So, when people see swallows flying low, they know it's going to rain.

Since ancient times, people are familiar with the precursors of rain, such as frogs chirping and swallows flying low, with high accuracy. There are also several kinds of ants crossing the road-ants digging holes in the ground for a living.

Knowing that the cave would be flooded when it rained, he ran away just before it rained. Earthworms come out of the hole-the ground is wet and soft, and earthworms will climb out of the ground, which is also a sign of rain. Besides, there are swarms of mosquitoes, swarms of rain ants, cats washing their faces, and so on.
