“exclusively”还原到语境中: amphipod“不仅仅”是一种海洋生物,还是我们所知道的sandhoppers。对应的含义是:restricted to the group, or area concerned,所以和sole:one and only的含义对应。
B选项incompatible: so different in nature as to be incapable of coexisting。
C选项fashionable: Characteristic of, influenced by, or representing a current popular style。
D选项conspicuous: clearly visible。
三个选项均和语境无关。
