课时跟踪练(一) Introduction & Reading Pre-reading.阅读理解AThough much effort and many resources have been spent in protecting the endangered giant panda, research by an international team of scientists shows that much suitable panda habitat is outside the nature reserves and areas where the panda is reported to live.“This research can help the Chinese government and international nongovernmental organizations develop full strategic (战略上的) plans for more effective conservation of the panda，” said Jianguo “Jack” Liu, MSU University Distinguished Professor of fisheries and wildlife.“Overall, about 40 percent of the suitable habitat for pandas is inside the nature reserves，” said Andres Vina, a specialist. “But we have also identified potentially suitable habitat outside the reserves.”The giant panda is the rarest member of the bear family. Pandas once ranged throughout most of China, northern Vietnam and northern Myanmar. Today, fewer than 1,600 giant pandas live in the wild in three Chinese provinces: Gansu, Shaanxi and Sichuan. Human actions including logging (伐木), residential development and the expansion of farming are considered the main reasons for the dramatic decrease of the giant pandas habitat.The research team developed habitat models using geographical and environmental information gathered by satellites overlaid with information on panda occurrence. After analyzing six mountain regions in the three provinces where pandas are known to live, the scientists developed a habitat suitability index (索引) for the entire 48,328 squaremile area. The rangewide habitat analysis model gives the government and other agencies a new tool as they develop conservation strategies not only for pandas but also for many other endangered species.“The Chinese government plans to add about 69,500 square miles of land to the countrys nature reserve system between 2010 and 2020，” said Ouyang Zhiyun, director of the Lab of Urban and Regional Ecology at the Chinese Academy of Sciences in Beijing. “So opportunities exist to create new reserves, to expand existing reserves and to create pathways that increase the connectivity among the reserves. On the basis of our results, we suggest some new areas be included in Chinas nature reserve system.”语篇解读：中国的大熊猫是一种珍贵的濒临灭绝的动物。那么造成它现状的原因有哪些？我们该采取什么措施来保护大熊猫呢？1Which of the following is NOT true?AChina has made lots of efforts to protect the giant panda.BPandas live better only outside the nature reserves.CMore plans should be created to protect the giant pandas.DLiu Jianguo is a professor who devotes himself to fisheries and wildlife.解析：选B推理判断题。根据第一段的“Though much effort”可知A项正确；根据第二段的“develop full strategic (战略上的) plans for more effective conservation of the panda”可知C项正确；根据第二段的“Professor of fisheries and wildlife”可知D项正确；第一段说自然保护区外还有许多适合大熊猫生存的栖息地，并没说大熊猫在外面生活得更好，故选B。2The purpose of developing habitat models is _.Ato know where pandas actually live in ChinaBto build a larger nature reserve for the pandasCto develop conservation strategies for endangered speciesDto give governments a warning解析：选C细节理解题。根据第五段最后一句话“.not only for pandas but also for many other endangered species.”可知答案为C项。3The underlined word “overlaid” in the fifth paragraph probably means “_”AcoveredBconnectedCcoped Dvaried解析：选A词义猜测题。此处表达：由卫星收集的信息覆盖着熊猫出现的信息。be overlaid with“被覆盖着”。4What can we learn from the last paragraph?AOuyang Zhiyun hopes more areas will become nature reserves in China.BChina has about 69,500 square miles of nature reserves now.CThe existing reserves will remain the same.DThe existing reserves shouldnt be expanded.解析：选A推理判断题。从最后一段的“to create, to expand, be included”可以推断出他希望在中国有越来越多的保护区出现，故选A项。BGeorge was a game warden (猎物繁殖和保护区的管理员) in Kenya. One day, he found three tiny lions beside a dead lioness. They were so little that their eyes had not yet opened. Sadly, he took the three little lions and drove back home.When George got out of the car with the baby lions, his wife Joy Adamson immediately took over. Joy had cared for many young animals over the years, but she had never tried to raise baby lions! However, she was determined to save these babies.The lions grew rapidly. But as the lions grew bigger and stronger, Joy and George realized they could not keep three large lions. They decided to present two of the lions to a zoo; they would keep the smallest lion, which they named Elsa.Joy and George taught Elsa to hunt and to protect herself. Elsa liked to play with her human friends, but as Elsa grew to her adult size, this play became dangerous. More than once, Elsa knocked Joy to the ground, scratching (抓伤) her. Joy and George both realized that it was time to find Elsa a new home. They knew she needed a wild home where she could live the life she was born to lead. Finally, Joy and George decide to set Elsa free in Meru Park at the foot of Mt. Kenya.E
