Around 100 years ago, there were thought to be no goshawks ___2___(leave), due to farmers hunting them and their woodland habitats being cut down. However, thanks to conservationists, goshawks are back. By monitoring their nesting sites over time, the teams have been able to protect them from further forestry work. As a result, their number ___3___(grow) from just 20 pairs to 40 pairs in the past two years. 【答案】1. its 2. left 3. has grown 【解析】 这是一篇说明文。主要介绍了一种曾经濒临灭绝的稀有鸟类——苍鹰，在英格兰南部的一个国家公园数量翻了一倍。这都多亏了自然资源保护主义者的工作。 【1题详解】 考查代词。句意：苍鹰，一种曾经濒临灭绝的稀有鸟类，现在在英格兰南部的一个国家公园里它的数量翻了一番。number为名词，应用形容词性物主代词its修饰。故填its。 【2题详解】 考查非谓语动词。句意：大约100年前，人们认为那里已经没有苍鹰了，因为农民在捕猎它们，而它们的林地栖息地也被砍伐了。分析句子结构可知leave在句中应用非谓语动词形式，与逻辑主语goshawks构成被动关系，故用过去分词。故填left。 【3题详解】 考查动词时态。句意：因此，在过去的两年里，它们的数量从20对增长到了40对。根据后
