Time was when biologists somewhat overworked the evidence that these creatures preserve the health of game by killing the physically weak, or that they prey only on “worthless” species.
【分析】
①本句为复合句,句子主干为主系表结构Time was when...,其中表语由when引导的从句充当。time was when 相当于there was a time when...,意为“曾经何时”,when从句引出一件过去曾发生的事(但现在情况已改变了)。
②when 引导的表语从句中,evidence后接有两个that引导的由or连接的同位语从句,说明是什么证据。
【译文】
曾经有段时间,生物学家或多或少滥用了一种证据,即这些生物通过杀死体弱者来保持种群的健康,或者说它们仅仅捕食没有价值的物种。
