三、保护野生动物的方法
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。
Some people argue that wildlife conservation should focus 31． the whole ecosystems(生态系统) instead of single species. Others support the umbrella method — by 32． (live) in a celebrity species' habitat, smaller creatures 33． (protect) as well. The thing is, that only works in some 34． (situation). Take the beloved giant panda for example. By putting so much effort into the 35． (nation) icon, China has at least partially protected many of the native forest birds and mammals in the panda's habitat, such as the endangered golden snub-nosed monkey, says Duke University conservationist Stuart Pimm.
On 36． other hand, the endangered purple frog, 37． (find) only in the Bengal tiger's range of India's Western Ghats, has not benefited from massive investments in the tiger's habitat. That's because 38． the purple frog needs to grow — land with fast-flowing streams and largely free of roads — is different from the things that the tiger needs.
Pimm also offers these words of caution: that even 39． (careful) made, supposedly scientific conservation methods may have faults — and may provide "an excuse not 40． (make) tough decisions about conservation."
【答案】31．on / upon；32．living；33．will be protected / are protected；34．situations；35．national；36．the；37．found；38．what；39．carefully；40．to make
【解析】【分析】本文是一篇说明文，介绍了保护野生动物的方法。
【点评】考查语法填空，本题考点涉及介词，非谓语动词，时态语态，名词，形容词，冠词，主语从句以及固定搭配等多个知识点的考查，要求考生在理解细节信息的基础上，进一步根据上下文的逻辑关系，并结合相关语法知识，进行分析推理，从而写出正确的单词形式。
31．句意：有人认为，野生动物保护应该着眼于整个生态系统，而不是单一物种。 focus on / upon 固定短语，“聚焦”，故填 on / upon 。
32．句意：其他人支持伞式方法——通过生活在名人物种的栖息地，较小的生物也受到保护。此处动名词作介词宾语，故填living。
33．句意：其他人支持伞式方法——通过生活在名人物种的栖息地，较小的生物也受到保护。此处是谓语动词，与主语 smaller creatures 是被动关系，应用被动语态，结合语境应用一般现在时或者一般将来时，故填 will be protected / are protected 。
34．句意：问题是，这只在某些情况下有效。此处名词作介词宾语，结合语境应用复数形式，故填 situations 。
35．句意：杜克大学保护主义者斯图尔特·皮姆说，通过为这个国家标志付出如此多的努力，中国至少部分保护了熊猫栖息地中的许多本土森林鸟类和哺乳动物，例如濒临灭绝的金丝猴。此处形容词修饰名词 icon ，作定语，故填 national 。
36．句意：另一方面，仅在印度西高止山脉的孟加拉虎范围内发现的濒临灭绝的紫蛙并没有从对老虎栖息地的大规模投资中受益。on the other hand固定短语，“另一方面”，故填the。
37．句意：另一方面，仅在印度西高止山脉的孟加拉虎范围内发现的濒临灭绝的紫蛙并没有从对老虎栖息地的大规模投资中受益。 the endangered purple frog 与find 在逻辑上是动宾关系，过去分词表被动，此处作定语，故填found。
38．句意：那是因为紫蛙需要生长的东西——水流湍急且基本上没有道路的土地——与老虎需要的东西不同。 the purple frog needs to grow是主语从句，从句中缺少need的宾语，应用what，故填what。
39．句意： Pimm 还提出了这些警告：即使是精心制作的、据称是科学的保护方法也可能存在缺陷——并且可能提供“一个不为保护做出艰难决定的借口”。此处副词修饰过去分词，故填 carefully 。
40．句意： Pimm 还提出了这些警告：即使是精心制作的、据称是科学的保护方法也可能存在缺陷——并且可能提供“一个不为保护做出艰难决定的借口”。此处不定式作定语，故填 to make 。
