Consider butterflies, for 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. 2 But, did you know how butterflies become the flying insects? It’s one of the amazing wonders of nature. In the beginning, female butterflies lay a small and colorful egg on a leaf or stem（茎） of a plant. It’s hard to believe that the egg will become something completely different in a few days. It becomes a walking insect. This insect is called caterpillar. It now has legs, eyes and a large body. A new life has begun. The caterpillar can eat, walk and see. But it is still not a butterfly. 3 Soon, after growing big, the caterpillar makes a cover for itself. It covers itself in the nice protective blanket（保护层） and goes to sleep. This stage is known as the “pupa（蛹）” stage. After a period of time, the blanket breaks and a wet, weak butterfly appears. It now has six legs, a mouth, eyes and wings. Shortly, the wings fill with blood, and the beautiful, colorful butterfly spreads its wings and flies away. After a few weeks, this adult butterfly lays her eggs, and the cycle begins all over again. 4 This is just one example of the wonders of nature. Look around the natural world, and you will learn many truly amazing things. 5 1.Which of the following are mentioned in Paragraph 1?___ ①Butterflies are a kind of insect. ②Butterflies are good at flying. ③Butterflies have colorful wings. ④Butterflies have a good sense of smell.
