【选项释义】 A. but the Asiatic musk deer has this organ但亚洲麝有这个器官 B. this organ found in the Asiatic musk deer这种器官存在于亚洲麝身上 C. however this organ is found in the Asiatic musk deer但是这种器官在亚洲麝身上发现了 D. this organ is found in the Asiatic musk这种器官存在于亚洲麝身上 【考查点】句法结构 【解题思路】空格前的句子是让步状语从句，空格处应填入主句，D选项是完整的句子，故D选项正确。 【干扰项排除】 A选项，Although不能与but连用，不符合语法逻辑； B选项不是完整句子，found in the Asiatic musk deer是过去分词短语作定语，不符合语法逻辑； C选项，however与句子之间要有逗号隔开，不符合语法逻辑。 【句意】虽然鹿科的所有普通成员都没有胆囊，但亚洲麝香却有这种器官。
