    The giant panda is one of the most popular animals in the world. A giant panda can grow up to 1.5       meters long and weigh up to 160kg. People think the giant panda is very lovely. ① So it is not surprising    that the World Wide Fund for Nature chose the giant panda as its symbol. The WWF tells people about   animals that they are in danger and raises money to save them.

    The giant panda only lives in the wild in China. In the early 1980s,were only 1,000 left in the wild, the    main reason why pandas are endangered is that the area where panda can live has become smaller.

    The WWF works to help giant pandas in the wild in many ways. One of the ways that helps them is to   increase the size of panda reserves （自然保护区）.Some reserves need to be joined together by          planting bamboo between them to make “corridors” . 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.②People are working very hard to make sure the giant panda does not die out.
