【解析】
这是一篇说明文。文章主要讲述了很长一段时间以来,蝙蝠一直被认为是动物界最可怕的生物之一,但其实蝙蝠在保持生态系统平衡方面发挥着重要作用。
【1】考查时态。句意:很长一段时间以来,蝙蝠一直是动物界最可怕的生物之一。根据前面的时间状语“For a long time”以及句意可知,此处应用现在完成时表示从过去以来一直持续的情况。故填have been。
【2】考查固定短语。be related to是固定短语,意为“与……有关”。故填related。
【3】考查形容词。此处应用形容词修饰后面的名词disease vector。故填dangerous。
【4】考查表语从句。be动词后是表语从句, that引导表语从句不做成分,只起连接作用,the fact is that意为“事实是……”。故填that。
【5】考查动名词。分析句子可知,此处have是动词,意为“拥有”,空格前的介词of后面接动名词。故填having。
【6】考查冠词。the size of是固定短语,意为“……的尺寸”。故填the。
【7】考查名词。根据前面的形容词essential可知,此处应用名词形式。故填addition。
【8】考查介词。contribution to是固定短语,意为“对……贡献,促成”。故填to。
【9】考查固定短语。at least是固定短语,意为“至少”。故填least。
【10】考查代词。make one’s way是固定短语,意为“成功,前进”,所以此处应用形容词性物主代词its修饰名词way。故填its。
