READING COMPRHENSION 1: Everybody loves the giant panda. That was clear from the enthusiastic welcome New Yorkers gave to Ling Ling and Yong Yong when they arrived at the Bronx Zoo in May. The cuddy black and white pair were on loan for six months from China’s Beijing Zoo, and it was estimated that more than 1 million people visited them in New York before they left for a zoo in Tampa, Florida in early November.
 The giant panda, unfortunately, is an endangered species. Only about 700 are left in the wild, most of them living on reserves in China’s Sichuan Province. Despite conservation efforts on the part of the Chinese government and scientists worldwide, the population continues to decline as human beings cut down bamboo, the panda’s primary food. Can the panda be saved ? Of course. All it needs is bamboo and peace. Every panda population should have at least two bamboo species available to lessen the impact of a die-off. Bamboo at low elevations must be preserved or replanted. Existing reserves need to be explanded and new reserves created. Poaching must be controlled. Zoos must improve captive breeding to provide more pandas for their original home. 
China’s Ministry of Forestry and the World Wildlife Fund are continuing their collaborative effort on the panda’s behalf, guided by the spirit of their joint agreement that reads: “The giant panda is not only the precious property of the Chinese people, but also a precious natural heritage of concern to people all over the world.”

READING 2 : In today’s world, thousands of plants and animals are in danger of extinction, and the number of species at risk increases every year. Not all plants or animals existing in small numbers are endangered as their population may not be decreasing or threatened. An endangered species is one which is expected to die out within twenty years unless special measures are taken to protect it. Endangered animals include blue whales, giant pandas, orang-outans, rhinoceros, snow leopards, tigers and some species of crocodile. Endangered plants include some species of cactus Why are the above species of animals endangered? There are now legal limits on hunting, but not all species protected are by law. Even when animals are legally protected, illegal hunting for fur, tusks and horn continues. Those animals that are not killed are captured and sent to zoos or sold as pets. For example, the little blue macaw, a parrot native to Brazil, has been captured in such numbers for private bird collectors that it is almost extinct in the wild. In addition to this, many species’ habitats are eliminated when people clear land in order to built on it, or when they introduce domestic and non-native animals which overgraze the vegetation and even prey on birds and mammals which are already at risk of extinction 
 Why is it important to save endangered species? Firstly , nature is delicately balanced, and the extinction of one species may have a serious effect on others. Secondly, it is the fault of one species may have a serious effect on others. Secondly, it is the fault of mankind that so many it is the fault of mankind that so many species are endangered, so it is our responsibility to protect those species while we still can.
