Consider butterflies, for example. ___1___ They can show their wonderful flying skills with their wings. On summer days, you always see them flying freely over flower gardens and wild fields. ___2___
The process includes four stages (阶段). In the first stage, female (雌的) butterflies lay a small and colorful egg on a leaf or a stem (茎) of a plant.
In the second stage, it becomes a walking insect. This insect is called caterpillar (幼虫). It now has legs, eyes and a large body. ___3___ A new life has begun, but it is still not a butterfly.
The next stage is known as the “pupa (蛹) stage”. After growing big, the caterpillar covers itself in the nice protective blanket (保护层) and goes to sleep.
___4___ It looks quite different. It now has six legs, a mouth, eyes and wings.
After a few weeks, this adult butterfly lays her eggs, and the cycle (循环) begins all over again. ___5___ Look around the natural world, and you will learn many truly amazing things.
