【题目】When entering the office, _____.
A. Winifred was found sitting at a desk B. Winifred was found sat at a desk
C. we found Winifred seated at a desk D. we found Winifred seating at a desk
在线课程【答案】C
【解析】
考查状语从句的省略和动词的用法。句意：当我们走进办公室时，我们发现Winifred坐在一张桌子旁。主从句主语一致，状语从句主语省略，seated表示“坐”的状态,，所以不能用seating，故选C。
