She is catching a fly.Let's actThe Cycle of the Frog At the beginning of spring, a big frog lays many eggs in the water. They are black. Some days later, the eggs become small tadpoles. They have a big round head and a long tail. They eat float grass. They have two hind legs(后腿） first, and then they have two front legs. Their tails are shorter and shorter. Their bodies become brown. At last their tails disappear(消失）and they are green now. They have a smooth, moist skin, webbed feet. The frogs can leap with long hind legs. They are beneficial（有益的）insects and the friends of human being. We should protect them.Once I was a caterpillar,
Sitting on a leaf.
But now I am a butterfly,
Flying high in the bright blue sky.Once I was a baby,
Crying in my bed.
But now I am big and tall,
Playing happily with my football.Say a chant If you keep trying, you will be beautiful butterflies.
