It serves as a vital wintering ground (越冬地) for migratory birds（候鸟） along the East Asian-Australasian Flyway. Every winter, the lake hosts nearly 400 bird species and around 700,000 birds, including more than 90 percent of the world's Siberian white cranes(白鹤) . However, this paradise is facing serious threats. Illegal hunters kill birds for money. Sand mining boats (采砂船) destroy the wetland（湿地）. The Yangtze finless porpoises (长江江豚) are being threatened by shipping and fishing nets. Fortunately, the government is taking strong action. Since Jan. 1, 2020, a comprehensive fishing ban (全面禁渔) has been enforced along the Jiangxi section of the Yangtze River and across Poyang Lake. Farmland is being returned to the lake. Volunteers and local rangers（巡护员） are watching over the birds day and night. The measures are working. Finless porpoise numbers in the Shangrao area have reached over 200, and wintering white crane numbers have exceeded 4,000 in recent seasons. Public awareness is also being raised through education programs. ① 鄱阳湖面临哪些问题？ ______________________________________________________________ ② 人们采取了哪些措施？请区分不同角色的行动措施。 ______________________________________________________________ 【参考答案】（先独立完成作业，再核对订正。） Task 1 · 问题：① illegal hunting；② habitat loss；③ water pollution；④ die out/drop at an alarming rate；⑤ an endangered species；⑥ be in danger of extinction · 措施 · 政府 / 组织：⑦ set up national nature reserves；⑧ place...under national protection；⑨ carry out/enforce a fishing ban；⑩ return farmland to lakes/forests · 志愿者 / 一线人员：⑪ watch over...day and night；⑫ rescue injured animals · 普通人（含我们）：⑬ raise public awareness(三方均可)；⑭ refuse to buy wildlife products；⑮ not feed or disturb wild animals；⑯ change our way of life；⑰ live in harmony with nature；⑱ *call on/appeal to more people to protect wildlife Task 2 (1) habitat loss 　 (2) drop at an alarming rate （用动词原形做made的宾补）　(3) in danger of extinction (4) set up national nature reserves　 (5) watched over　 (6) an endangered species　 (7) live in harmony with nature 思考任务：第一段：severe threats to Tibetan antelopes 第二段：Protection measures for Tibetan antelopes 第三段：Effects of protection & appeals Task 3（参考，答案不唯一） 1　 appeal to the public to protect this endangered species 2　 put forward practical suggestions for their protection 3　 pose a severe threat to Tibetan antelopes 4　 set up more national nature reserves and place them under national protection 5　 stop being a threat to Tibetan antelopes and other wildlife 6　 joint efforts will bring about harmony between humans and nature 完整句式翻译： · 了解到藏羚羊依旧面临严峻的生存挑战，我觉得我有责任呼吁大众保护这一濒危物种。 · 出于对藏羚羊艰难处境的担忧，我写此信提出切实可行的保护建议。 · 即便到今天，非法捕猎与栖息地丧失依旧对藏羚羊构成严重威胁。 · 为使藏羚羊免于灭绝，政府应当设立更多国家级自然保护区，将它们纳入国家保护之下。 · 只有当我们改变自身的生活方式，我们才不会对藏羚羊以及其他野生动物构成威胁。 · 我们坚信，共同的努力终将实现人与自然的和谐共处。 Task 4（参考示例，完整句子） 1　 Illegal hunting, wetland destruction, shipping and fishing nets bring great threats to wildlife in Poyang Lake. 2　 In order to save Poyang Lake from these severe threats, the government enforced a comprehensive fishing ban and returned farmland to the lake.
