头的上部，用肺呼吸。体长可达三十米，是现在世界上最大的动物。
鲸为适应水中生活，减少阻力，它们的后肢消失，前肢变成划水的浆板。身体成为流线型，酷似鱼。因而它们的潜水能力很强，小型齿鲸可潜至100-300米的水深处，停留4-5分钟，长须鲸可在水下300-500米处待上1小时，最大的齿鲸--抹香鲸能潜至千米以下，并在水中持续2小时之久。【来源：21cnj*y.co*m】

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 160 kg. People think the giant panda is very lovely. So it is not surprising that the World Wide Fund for Nature chose(选择)the giant panda as its ①symbol. 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 1，000 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 ha to make sun he giant panda does not die out. 2-1-c-n-j-y
