【解析】

這是一篇說明文。文章主要講述了很長一段時間以來，蝙蝠一直被認為是動物界最可怕的生物之一，但其實蝙蝠在保持生態(tài)系統(tǒng)平衡方面發(fā)揮著重要作用。

【1】考查時態(tài)。句意：很長一段時間以來，蝙蝠一直是動物界最可怕的生物之一。根據(jù)前面的時間狀語“For a long time”以及句意可知，此處應用現(xiàn)在完成時表示從過去以來一直持續(xù)的情況。故填have been。

【2】考查固定短語。be related to是固定短語，意為“與……有關”。故填related。

【3】考查形容詞。此處應用形容詞修飾后面的名詞disease vector。故填dangerous。

【4】考查表語從句。be動詞后是表語從句， that引導表語從句不做成分，只起連接作用，the fact is that意為“事實是……”。故填that。

【5】考查動名詞。分析句子可知，此處have是動詞，意為“擁有”，空格前的介詞of后面接動名詞。故填having。

【6】考查冠詞。the size of是固定短語，意為“……的尺寸”。故填the。

【7】考查名詞。根據(jù)前面的形容詞essential可知，此處應用名詞形式。故填addition。

【8】考查介詞。contribution to是固定短語，意為“對……貢獻，促成”。故填to。

【9】考查固定短語。at least是固定短語，意為“至少”。故填least。

【10】考查代詞。make one’s way是固定短語，意為“成功，前進”，所以此處應用形容詞性物主代詞its修飾名詞way。故填its。
