How do tadpoles grow into frogs?

1. One afternoon in spring, Mei Mei came to the river. She saw many tadpoles in the river, so she fished them up with a net bag. After catching them, Mei Mei went home. After several days of observation, the tadpole grew up slowly and had two hind legs. Mother said to Mei Mei, "Do you know what a tadpole is when it grows up?" Mei Mei said, "I don't know."

Mother said, "Little tadpoles grow up to be frogs. They are different insects. They can protect crops and eat pests, so Meimei, please put your tadpoles back in the water. " Meimei was very ashamed after hearing this, so she gently put the tadpole back into the water with a small bucket.

2. In spring, Honghong uses a net bag to catch tadpoles by the river. What a lovely tadpole! Honghong took it home. A few days later, Honghong found that the tadpole's tail became shorter and its two hind legs became longer. Honghong was curious, so she went to ask her mother, who said, "Little tadpoles will become frogs when they grow up. They will help farmers catch pests in rice fields and are our friends. "

Honghong was ashamed to hear that. She quickly came to the river with a bucket, gently put the tadpole back into the water and quietly said to it, "Little tadpole, you must grow up quickly and help the farmer catch pests in the field."
