Nature is amazing! Take a close look at the world of insects (昆虫) and you will discover many unbelievable things. Consider butterflies, for example. They have beautiful, colorful wings, and strong. steady flying skills. On summer days, we see them flying gracefully over flower gardens and wild fields.
But, do you know that butterflies live three separate lives before they become the flying insects we all know? They begin their lives as one thing, change into another, and then another. Finally, they change into beautiful flying insects. It’s true. And it’s one of the wonders of nature.
In the beginning, there is an egg, it’s usually small and colorful. A female butterfly lays an egg on a leaf of a plant. When you look at this tiny egg, it’s hard to believe that in a few days, it will become something completely different.
In time, it changes into a new life. No longer the small egg becomes a walking insect. This insect is called a caterpillar. It now has legs, eyes, a mouth and a large body. A new life has begun. The caterpillar eats, and eats, and eats. It can walk. It can see. But it is still not a butterfly. Soon, after growing big, the Caterpillar makes a cover for itself. It wraps (包裹) itself in this nice protective blanket and goes to sleep. This stage (阶段) of a butterfly’s life is known as the “pupa” stage.
What happens next is truly amazing!
After a period of time, the blanket breaks and a wet, weak butterfly appears. It now has six legs, a mouth, eyes and wings. Soon, the wings fill with blood, and the beautiful, colorful butterfly spreads its wings and flies away.
After a few weeks pass, this adult butterfly lays her eggs, and the cycle begins all over again.
This is just one example of the wonders of nature. Look around the natural world, and you will learn many truly amazing things.

Students who get tired of looking at the four walls of a classroom might like to take the nature course being offered by Carvel College again this summer. Groups of about a dozen students each, led by an experienced guide, will go on ten-day camping trips to the mountains to study the plants and animals that grow and live there.
Students carry their own things, which includes sleeping bags, warm clothing, food and water, and other useful tools. And what do the students do all day? Well, as soon as the sun comes up, they eat breakfast and start climbing up the mountain trail to the next campground, which is five to ten miles away. As the students take notes, the guide points out different plants and animals alongside the trail. The climb is usually over by early afternoon, so the group spends the rest of the day resting or swimming in a mountain lake. Before dinner each night, they all come together and discuss the day’s activities.
At the end of the course, the students write reports using the information they have collected. But they don’t mind at all. What they do mind is leaving the beauty of the wilderness and the good friends they’ve made to return to their normal lives in the city.

A cicada is a large insect. It is about three centimeters long. Like many other insects, it has six legs. On the forehead are two big eyes, between which is a long beak. It uses its beak to drink juice from trees. The adult cicada has two sets of wings which can shake together to produce a high, continuous sound when the weather is hot.
In its whole life, it mainly goes through two stages. In the beginning, when a cicada is under the ground, it is called a baby cicada. It drinks juice from tree roots and it is covered in a hard shell. At this time, it has no wings - just legs. After coming out of the ground, it breaks out of its old shell. Under the old shell is a new shell and four wings. The cicada finds a place in the sun to dry its new shell and wings. Gradually, the baby cicada grows into an adult. After a cicada becomes an adult, it sings loudly in hot summer. That’s why it is called a born singer in nature.
At present, over two thousand kinds of cicadas are distributed (分布) around the world. All of them spend most of their life underground. You can find about four hundred and fifty kinds in Africa. Besides, there are about one hundred and twenty kinds in China. There are also about seven special kinds in the US that stay under the ground for many years.

A number of amazing plants grow in the nature world, including bamboo. Many people prefer to call it a tree because of its shape and size. In fact, it is a kind of grass.
Like other kinds of grass, a bamboo plant may be cut very low to the ground, but it will grow back very quickly. A Japanese scientist recorded one bamboo plant which grew almost 1.5 metres in 24 hours! Bamboo grows almost everywhere in the world except Europe. There are more than 1, 000 kinds of bamboo which grow around the world on both mountains and plains（平原）.
Not all bamboo looks the same. Some are very thin. They may only grow to be a few centimeters wide while others may grow to more than 30 centimeters across. This plant also comes in a variety of colors, from gold to black to green.
Bamboo has been used to make many things, such day-to-day items as hats and kitchen tools. Because it is strong, bamboo can also be used to build buildings.
Many Asian countries have been using bamboo for hundreds of years. They often use bamboo for building and supporting new buildings while they are being built. The cables（缆绳）which hold up the hanging bridge across the Min River in Sichuan, China are made of bamboo. The bridge has been in use for more than 1, 000 years, and it is still holding strong.
As we know, pandas feed on the plant of bamboo. But not all of them fill their appetite（胃口）, only about 20 kinds of them can be their fine food.
