Unit 4 Wildlife protection
【美文阅读】
动物是人类最亲密的朋友，但现在世界上很多野生动物正濒临灭绝。

因此挽救并保护它们是我们义不容辞的责任。

珍稀的藏羚羊就在这些即将灭绝的动物之列，让我们来了解一下它们的现状吧！
The Tibetan antelope is listed in the IUCN(国际自然与自然资源保护联合会) Red List as a threatened(有灭绝危险的)species.Several nature reserves were set up by the central government to protect these antelopes.Each year, Tibetan antelopes move to the northern area with a cooler climate and rich water and grass resources to lamb in June～July and return with their children in August.The Qinghai－Tibet Railway lies right in their path.In June, 2002，in order to let some 30，000 future mother antelopes pass the construction(建设)site without disturbance(扰乱，打扰)，the workers shut down their ma－
chines and pulled down their sign boards and sign flags.They stopped working for four days to make way for them.In August, when these Tibetan antelopes returned with their children, they stopped working once again.Moreover(而且，此外), the builders did their best to reduce noise in areas close to nature reserves.
So far, the number of Tibetan antelopes in China has climbed to over 80，000.
【诱思导学】
1．Why do Tibetan antelopes move to the northern area each year?
2．What did the workers do to help the antelopes?
【答案】 1.Because natural conditions there help their newborn children grow up. 2.They stopped working to make way for them and did their best to reduce noise in areas close to nature reserves.
