In the early days of longline fishing, a lot of fish were lost to sharks after they had been _______.A. copedB. preservedC. renderedD. hooked

本题考查词汇辨析，解题思路是理解句子语境，分析每个选项单词的含义，看哪个选项能使句子逻辑通顺。

• A选项“coped”：“cope”常见含义为“处理；应对”，“cope with”是常用搭配。在本句中，“fish were lost to sharks after they had been coped”，鱼被应对之后丢失给鲨鱼，这种表达不符合逻辑，所以A选项不正确。
• B选项“preserved”：“preserve”意为“保存；保护；腌制”。“fish were lost to sharks after they had been preserved”，鱼被保存之后丢失给鲨鱼，通常保存是为了防止丢失，该选项不符合句子逻辑，所以B选项错误。
• C选项“rendered”：“render”有“使得；给予；提供”等意思。“fish were lost to sharks after they had been rendered”，鱼被使得之后丢失给鲨鱼，这种表达不清晰且不符合常理，所以C选项不合适。
• D选项“hooked”：“hook”作动词有“用钩钩住”的意思。在钓鱼场景中，鱼被钩住后很容易被鲨鱼抢走，“fish were lost to sharks after they had been hooked”，即鱼被钩住之后丢失给鲨鱼，符合句子的逻辑和语境，所以D选项正确。
