文章解析
第一段: 第一句: The waters east of Cape Hangklip were once the center of a lucrative wild-caught abalone fishery, but illegal fishing in the mid-1990s escalated to such levels that the recreational fishery was closed in 2003. 白话版讲解: Cape Hangklip 的东部海域曾经因为野生鲍鱼捕捞业而收入颇丰,但由于非法渔业在20世纪中期愈发猖獗,该地区的休闲渔业最终在 2003 年关停了。 第二句: When abalones did not rebound, commercial fishing was also banned. 白话版讲解: 当鲍鱼数量减少到一定程度,无法恢复到之前的数量的时候,商业渔业也被禁止了。 第二段: 第一句: Continual declines in abalone were attributed to poaching, but an invasion by rock lobsters during the early 1990s probably intensified the trend. 白话版讲解: 非法捕捞导致了鲍鱼数量的持续减少,而 20 世纪 90 年代岩虾的入侵也进一步地加剧了这一趋势。 第二句: Rock lobsters prey on sea urchins, and increased rock lobster densities coincided with significant decreases in urchins. 白话版讲解: 岩虾吃海胆,所以岩虾的增加使得海胆数量减少了。 第三句: In that area, urchins feed largely by trapping drift kelp, and in doing so provide juvenile abalone with both protective shelter and nourishment. 白话版讲解: 在这块区域里,海胆以飘动的海带为食,从而为了幼年的鲍鱼提供了保护和营养。 第四句: Without urchins’ presence, juvenile abalones are less likely to survive to adulthood. 白话版讲解: 海胆数量减少之后,幼年的鲍鱼就难以存活了。题目解析
