问题补充：

When I came in，I saw her in the sofa in thought．

A. sat；deep

B. sitting；deeply

C. seated；deep

D. seating；deeply

答案：

A. sat；deep

B. sitting；deeply

(答案→)C. seated；deep

D. seating；deeply

解析：试题分析：考查非谓语动词和副词deep的用法。seat为及物动词，后面不加宾语时用被动形式，即seated，而sit是不及物动词，用sitting形式，“deep in thought”指“陷入沉思”，所以答案选C。
