5、ported66.belief67.noting68.higher69.the70.are【解析】本文为科普类说明文。文章向我们介绍了目前北极熊的生存现状。近年来，在人类居住的地方看到北极熊的次数有所增加，这导致人们错误地认为北极熊的数量在上升，可事实并非如此。61.that考查名词性从句。根据句子结构分析可知，主句为therebe句型，且结构完整，空格后为同位语从句，解释说明中心词evidence内容，故填that。62.poorly考查形容词副词。分析可知，此处用副词poorly修饰谓语动词hasbeenstudied，意为“研究很

8、考查定冠词。此处特指“在已知的19个北极熊亚种群中”。故填定冠词the。70.are考查主谓一致。根据threearedeclining，此处数词six作主语，代指前文中的“polarbearsubpopu
