问题 However, at times this balance in nature is______ resulting in a number of possibly unforeseen effects.
选项 A、bewildered
B、disturbed
C、mystified
D、perplexed
答案B
解析 题意是：然而，有时______自然界的平衡将会带来许多可能无法预测的后果。[B]disturbed“打扰，干扰”，指较彻底、较持久的烦扰，强调由于外界的滋扰而使安定的或正常的秩序被扰乱，符合题意。[A]bewildered“使迷惑”，指事情混乱复杂、难度大，使人迷惑到茫然不知所措的地步；[C]mystified“迷惑，蒙蔽”，指引人困惑不解的迹象很多，往往处于调查研究的后一阶段；  [D]perplexed“使困惑，使为难”，着重指由于困惑不解而不安。因此这三项都不符合题意。
