任務型閱讀。
  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, there
were only l,000 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 helps them is to increase the size of panda reserves(自然保護區).
Some reserves need to be joined together by planting bamboo between them to
make "corridors". These are paths that lead from one reserve co another. No one
may harm the pandas in these areas. The corridors let pandas move from one
habitat(棲息地) to another to look for food.② People are working very hard to
make sure the giant panda does not die out.
1. How long and heavy can a giant panda grow to be? 
                                                       
2.將文中劃線的句子①改為被動句.
So it is not surprising that _____by the World Wide Fund for Nature.
3. Why are the giant pandas endangered?
                                                       
4. Give a way to help the giant pandas in the wild, please.
                                                       
5. 將文中劃線的句子②翻譯成中文.
