Question

Entering the room, I found Mary ______at the desk and ______a letter.

A. Seated；wrote
B. Sitting；written
C. Seating；writing
D. Seated；writing

Answer 1

答案D
考查非谓语动词。seated和sitting 表坐着的状态，第一格分词作find后面宾语的补足语；根据句意，发现Mary正坐着，故seated 和sitting均可。排除C; 第二格，仍然是宾语补足语，补充说明Mary的状态，而Mary和write之间是主动关系，故用writing。
