    The giant panda is one of the most popular animals in the world. A giant panda can grow to be 1.5 metres tall and weigh up to 150 kg. People think the giant panda is very lovely. So it is not surprising that the World Wide Fund for Nature chose the giant panda as its symbol. The WWF tells people that giant pandas are in danger and raises money to save them.

    The giant pandas only live in China. There are fewer than 1, 600 giant pandas left in the wild. The main reason why pandas are endangered is that the area where pandas can live has become smaller.

    The WWF works to help giant pandas in the wild in many ways. One of the ways that help them is to increase the size of panda reserves. Some reserves need to be joined together by planting bamboo between them to make "corridors(通道) ". These are paths that lead from one reserve to another. No one may harm the pandas in these areas. The corridors let pandas move from one habitat(栖息地) to another to look for food.

    People are working very hard to make sure the giant pandas do not die out.

    Rainforests are magical(神奇的)places on earth, full of life and beauty. They are homes, to millions of birds, insects, animals, and plants. These forests are the world's natural treasure(财富).

    Most rainforests are near the equator(赤道). Some of the largest are in Brazil, South Asia and Central Africa. There are several kinds. Each has different levels of rainfall and different types of soil and temperature.

    In equatorial rainforests, the temperature stays between 25 and 35 degrees during the year. These rainforests get a lot of rain-as much as 4, 000 millimeters per year. Monsoon rainforests are very different. They have long dry periods. Also, their temperature can change a lot from season to season.

    Rainforests are important for many reasons. One is their great diversity(多样性)of life. There are millions of species of insects, animals, and plants. Scientists still don't know about most of them yet. Many rainforest plants could help us make new medicines. Rainforests also keep the soil strong. And they may be important to the earth's climate.

    Unfortunately, rainforests are getting smaller every year. Farmers burn down trees for land. Large companies cut down trees for their valuable wood. Other companies build mines near forests.

    Environmental groups are trying hard to save the rainforests. Hopefully they can, before they're all gone.
