题目

 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。 For protecting endangered neighbors, pandas make unreliable umbrellas.  Like many undergraduate biology students, Wang Fang was taught that pandas are a prime example of  umbrella species—a well-known and usually endangered animal  protection benefits an entire ecosystem.  In fact, the story is much  (complex), according to findings that Dr. Wang, now an ecologist at Fudan University in Shanghai, published last month in Biological Conservation. Refuting (反驳) years of  (assume) about the universal benefits of panda conservation, Dr. Wang and his colleagues report that a number of other  (threaten) species are not being protected by the panda umbrella.  Panda conservation, on its own, (be) a success up to now. In the 1980s, pandas had very little protection in the wild and were thought to add up to around just 1,100 individuals. In the 1990s, China began to (active) conserve wild populations. Eventually sixty-seven panda-specific protected areas (represent) 70 percent of the species' range were established. All of those efforts focused simply not on other species, on China's national animal. Dr. Wang began to question the umbrella species narrative and carried out research, only (find) that panda conservation had not helped large carnivores in China. 答案：【1】an【2】whose【3】more complex【4】assumptions【5】threatened【6】has been【7】actively【8】representing【9】but【10】to find
