31、因为最适合它们生存的场所还是长江，故A错误；让许多人到长江只会加剧白鳍豚灭亡而不是帮助它们，故D错误。4What can we learn from the passage?APeople can take some measures to save the animals dying out.BThe animals dying out are being hunted by human beings.CPeople like to live in the Yangtze River Basin with animals swimming in the river.DThere are mo

32、re Yangtze River dolphins living in a nature park now.答案：A推理判断题。根据全文内容推知人们可以采取措施减少濒临灭绝动物的数量，文章最后一段提到了一系列措施。故选A。B(2016北京高考)California Condors Shocking RecoveryCalifornia condors are North Americas largest birds, with winglength of up to 3 meters. In the 1980s, electrical lines and lead poisoning (铅中毒

33、) nearly drove them to dying out. Now, electric shock training and medical treatment are helping to rescue these big birds.In the late 1980s, the last few condors were taken from the wild to be bred (繁殖). Since 1992, there have been multiple reintroductions to the wild, and there are now more than 1

34、50 flying over California and nearby Arizona, Utah and Baja in Mexico.Electrical lines have been killing them off. “As they go in to rest for the night, they just dont see the power lines，” says Bruce Rideout of San Diego Zoo. Their wings can bridge the gap between lines, resulting in electrocution

35、(电死) if they touch two lines at once.So scientists have come up with a shocking idea. Tall poles, placed in large training areas, teach the birds to stay clear of electrical lines by giving them a painful but undeadly electric shock. Before the training was introduced, 66% of setfree birds died of e

36、lectrocution. This has now dropped to 18%.Lead poisoning has proved more difficult to deal with. When condors eat dead bodies of other animals containing lead, they absorb large quantities of lead. This affects their nervous systems and ability to produce baby birds, and can lead to kidney (肾) failu

37、re and death. So condors with high levels of lead are sent to Los Angeles Zoo, where they are treated with calcium EDTA, a chemical that removes lead from the blood over several days. This work is starting to pay off. The annual death rate for adult condors has dropped from 38% in 2000 to 5.4% in 20

38、11.Rideouts team thinks that the California condors average survival time in the wild is now just under eight years. “Although these measures are not effective forever, they are vital for now，” he says. “They are truly good birds that are worth every effort we put into recovering them.”篇章导读：本文是一篇说明文

41、can hardly be gotten rid of from condors bloodDmakes it difficult for condors to produce baby birds答案：D细节理解题。由第五段第三句可知，铅中毒影响到它们的神经系统和它们繁育小鸟的能力，故答案选D。8This passage shows that _.Athe average survival time of condors is satisfactoryBRideouts research interest lies in electric engineeringCthe efforts to

42、 protect condors have brought good resultsDresearchers have found the final answers to the problem答案：C推理判断题。由最后一段可知，尽管这些措施不会永久有效，但在目前是至关重要的，再结合第四段末尾及第五段末尾所给的数据可知，C项正确。应用文写作假定你是李华，家乡有一片湿地(wetland)，每到春天，有很多鸟类，包括一些珍稀、濒危鸟类。请根据下列要求和你的想象给WWF(世界野生动物基金)写一封信。1鸟类经常受到伤害；2湿地面积减少；3提出你的建议。 精彩范文Dear WWF，There are

44、icked up. Worse still, people even catch or poison birds for meat. The size of the wetlands is becoming smaller and smaller due to farming. Pollution from chemical factories is also a big problem. Fewer birds arrive here each year.I strongly suggest taking action to save the birds. A wetland reserve should be set up to make sure no one shall harm the birds. We human beings should live with birds peacefully and happily.Yours，Li Hua
