题目：
Coming into the room, I found them _______ at the table, ________ chess.
A．seated; played
B．seated; playing
C．seating; playing
D．seating; played
答案：
答案：B
题目分析：考查非谓语动词的用法。句意为：走进房间，我发现他们正坐在桌子旁下象棋。感官动词find/watch/notice/observe＋宾语+宾语补足语，Seat是及物动词，用be seated表示“就坐”，find sb seated发现某人坐在…，第二空playing是现在分词做伴随状语。选B。
