Do you want to know how and why a fall leaf changes color? We first have to understand what leaves are and what they do.

Leaves are the world's food factories. Plants take water from the ground through their roots and take CO2 from the air. Plants use sunlight to turn water and CO2 into glucose(葡萄糖), a kind of sugar. Plants use it as food for energy and growing.

A chemical called “chlorophyll” in the leaves gives plants their green color. As summer ends and autumn comes, the days get shorter and shorter, and trees “know” to begin getting ready for winter.

During winter, there is not enough sunlight or water. Trees rest during this time and live on the food they store during the summer. They begin to shut down their food?making factories. As the green chlorophyll disappears from the leaves, we begin to see yellow and orange leaves.

The bright reds and purples we see in leaves are made mostly in autumn. In some trees, like maples(枫树), sunlight and the cool nights of autumn turn the glucose in the leaves into a red color. And we can enjoy the beautiful red leaves during autumn.

In England, people often talk about the weather because they can have four seasons in one day. In the morning it is warm, just like in spring. An hour later, black clouds come out, and then it begins to rain and gets a little cold. In the afternoon the sky may be clear, and the sun may begin to shine. It may be just like a day in summer.

You can also have summer in winter, or have winter in summer. So in winter you can sometimes swim, and in summer you can sometimes wear warm clothes. When you go to England, you will see some Englishmen take an umbrella or a raincoat with them on a sunny morning. But you'd better not laugh at them. If you don't take an umbrella or a raincoat in the morning, maybe later you'll have to walk in the rain. People often say that in England you can have four seasons in one day. Sometimes you may feel you have the same season all the year round.

Zhalong is a nature reserve in Heilongjiang in north-east China. The reserve covers an area of 210,000 hectares. It is an ideal home for different kinds of plants, fish and birds.

Many birds live comfortably in Zhalong Nature Reserve all year round, while some only stay there for a short time. There are many fish in the wetlands, and the birds can easily catch them for food. Zhalong has long been called “the home of the crane”. There are 15 crane species (物种) in the world. 8 of them are in China and there are 6 species in Zhalong area. It is an important living area for the rare red-crowned cranes. There are not many red-crowned cranes in the world. Every spring and summer, red-crowned cranes lay and hatch (孵化) their eggs in Zhalong.

Some people want to change the wetlands for farms and buildings. More and more birds are in danger because they do not have enough living space. Many of them died. The Chinese government wants to protect these endangered birds, and they can be safe in Zhalong.

Every year, a lot of tourists go to Zhalong to watch birds. This year, members of our Bird-watching Club are going to study the different kinds of birds in Zhalong and the changes in their numbers. But many people do not understand the importance of the wetlands. We hope this information will help them understand and make them actively take action to protect wildlife.
