Look closely at the world of insects, and you will find many interesting facts. Let’s take butterflies as an example. They have beautiful, colorful wings and strong, fantastic flying skills. On summer days, you always see them flying freely over flower gardens and wild fields. ②But do you know how a butterfly grows? It is one of the most fantastic wonders (奇观) of nature. First, a butterfly lays (产卵) a small colorful egg on a leaf of a plant. ③It’s hard to believe that the egg will become something completely different in a few days. It becomes a walking insect called a caterpillar. It now has legs, eyes and a large body. A new life begins. The caterpillar can eat, walk, and see. But it is still not a butterfly. ④After the caterpillar grows big, it makes a cover to protect itself. It stays inside this soft cover and goes to sleep. We call it the “pupa” stage (成蛹阶段). ⑤After some days, the cover breaks open. A wet and weak (脆弱的) butterfly comes out. It has six legs, a mouth, eyes, and wings. Soon, the wings become dry and strong. The beautiful butterfly spreads (伸展) its wings and flies away. A few weeks later, this butterfly lays her eggs, and the life cycle starts again. ⑥This is just one example of the wonders of nature. Look around the natural world, and you will learn many truly amazing things. 1.What can we know about butterflies from Paragraph 1? A.Butterflies are a kind of insects.
