问题补充：

Entering the room,I found Mary at the desk and a letter.

A. seated;wrote

B. sitting;written

C. seating;writing

D. seated;writing

答案：

A. seated;wrote

B. sitting;written

C. seating;writing

(答案→)D. seated;writing

解析：考查非谓语动词：find+宾语+宾语补足语，第一空可以填sitting或seated，因为seat和Mary是被动关系，用seated做宾语补足语，sit和Mary是主动关系，用现在分词，第二空，填writing，因为mary和write是主动关系，用writing，句意：进入房间，我发现玛丽坐在桌子旁边，写一封信。选D。
