文章大意：本文是一篇说明文。文章介绍了北极熊种群数量越来越少、急须保护的现状。解析：1．考查同位语从句的引导词。分析句子结构可知，所填词引导同位语从句，解释说明evidence的具体内容，从句中不缺少成分且意义完整，故填that引导。2．考查词性转换(形容词变副词)。修饰动词studied应填形容词pr的副词形式prly。
3．考查介词。 a methd f/fr ding sth.做某事的方法。故填f/fr。4．考查非谓语动词。此处是“主语＋be＋adj.＋不定式”结构，不定式用主动形式表示被动含义。故填t perfrm。5．考查时态。根据句中的时间状语in recent years可判断用现在完成时。故填have reprted。6．考查词性转换(动词变名词)。根据空格前的不定冠词a可知，此处应填believe的名词形式belief(看法，信念)。故填nting。
7．考查非谓语动词。介词后接动词时，应用其动名词形式。respnd by ding sth.通过做某事回应。故填nting。8．考查形容词比较级。根据空格后的than可知，此处应填high的比较级形式higher。9．考查冠词。此处特指确认的19个亚种群，故填定冠词the。10．考查时态和主谓一致。此处陈述客观事实，应用一般现在时；six指代six plar bear subppulatins，谓语动词应用复数。故填are。
