UNIT 3　ENVIRONMENTAL PROTECTION [对应学生用书第49页] Wildlife protection is to protect human oneself! Many animals are being endangered or at the edge of disappearing.The following four species are the most endangered animals in the world. Today white elephants are very rare.The white elephant is a native of Southeast Asia.The last white elephant in Myanmar was seen in 1961.Elephants represent power and peace.To Americans, a white elephant is a Metaphor (隐喻) for a worthless object.To the people of Thailand, a white elephant is regarded as a sacred animal. The Tibetan antelope is prized for the fur around its throat.Experts guess that there are 75,000 to 100,000 Tibetan antelopes left and that as many as 20,000 a year are killed in China alone. There are five species of rhinos,two African species and three Asian species.The African species are the white and black rhinos.Both species have two horns.Asian rhinos each have one horn.Rhinos rank among the most endangered species on Earth.Valued for their horns, they face a serious threat from poaching. Chinese scientists find it hard to explain how the population of Pere David’s deer,known as Milu deer in China bounced back after dying out in China.The Dafeng Nature Reserve in Jiangsu Province introduced 64 Pere David’s deer in 1993 and 1994, and the population has grown to 450 today. Why are more and more animals, especially rare animals, are in danger of extinction? Firstly, if the environment is destroyed — for example, when farmers clear a forest for new fields, or trees are cut down for making money—many animals are unable to survive, and more species are likely to become extinct.Secondly, animals are being killed by hunters who hunt animals to make money.Some hunters even hunt animals simply for sports. Animals are our friends, so we humans should stop killing them and live in harmony with them. 1.edge n.　　　　　　　　边缘 2.rare adj.　　　稀少的;珍贵的 3.represent vt.　　　代表;象征;描绘 4.sacred adj.　　　神圣的 5.throat n.　　　喉咙 6.rhino n.　　　犀牛 7.hor
