1, text:

There are a group of tadpoles in the pond, with big heads and dark gray bodies, swinging their long tails and swimming around happily.

The tadpole swam and swam. After a few days, it grew two hind legs. They saw the mother carp teaching the young carp to hunt, so they greeted them and asked, "Aunt carp, where is our mother?" Carp mother said, "Your mother has four legs and a big mouth. You go there and look for it! "

The tadpole swam around, and after a few days, it grew two front legs. They saw a turtle swimming in the water, its four legs swinging, and quickly caught up with it, shouting, "Mom, Mom!" " The tortoise smiled and said, "I'm not your mother." "Your mother has two big eyes on her head and is dressed in green. You go there and look for it! "

Tadpoles swam over, and after a few days, their tails became shorter. They swam to the lotus and saw a big frog squatting on the lotus leaf, dressed in green, showing a white belly and protruding eyes.

The tadpole swam over and cried, "Mom, Mom!" " Mother frog lowered her head and said with a smile, "Good boy, you have grown into a frog." Jump on! ""They kicked their hind legs, jumped forward and jumped on the lotus leaf.

I don't know when the little frog's tail disappeared. They follow their mother to catch pests every day.

2. Moral:

This is a childlike character. In the process of looking for mother, a group of naive and lively tadpoles unconsciously turned into small frogs, helping mother catch pests together. The textbook presents the scientific knowledge of frog's growth process in the form of fairy tales, which contains the truth of being able to live independently and actively explore when something happens.
