A. sitting; fixing
(答案→)B. seated; fixed
C. sit; fixing
D. sitting; to be fixed
解析：句意：我发现她坐在阅览室里的一个桌子旁边，集中精力在读一本书。这里是固定短语find sb doing/done发现某人在做某事/被怎样，其中sb与do之间是主动关系；her与sit之间是主动关系；因为sb be seated某人坐着，her与seat之间是被动关系，故用过去分词，所以根据第一空排除C；第二空是with的符合结构；fix one’s attention on…集中精力于；with one’s attention fixed on…这时attention与fix之间是被动关系，所以用过去分词，故选B。
