Ladies and gentlemen,
It’s my great honor to give you a speech about the frog.
A frog is a cold-blooded animal, which lives both in water and on land. At first, it’s a spawn and about 10 days later, it will become a tadpole, which is a baby frog. The tadpole lives in water. After over 40 days, the tadpole grows into a young frog. Then the young frog jumps out of water and begins its life on land, feeding on insects. During the winter, it hibernates. When spring comes, it wakes up and jumps back into water to spawn and new frogs will be born.
Frogs can eat plant pests, so we should protect frogs and keep the balance of nature.
That’s all for my introduction to the frog.
Thanks for your attention.
