问题补充：

He was found in front of the TV set， the football match

A. to sit；to watch

B. seated；watching

C. seating；watching

D. seated；watched

答案：

A. to sit；to watch

(答案→)B. seated；watching

C. seating；watching

D. seated；watched

解析：本题考查非谓语动词。Sit坐，使就坐；seat使……坐下，可容纳……的；watch观看。句意：发现他坐在电视前看电视。过去分词作补足语表示被动的动作，和句子主语是动宾关系。现在分词作状语表示正在进行的伴随性动作，和句子主语是逻辑上的主谓关系。结合语境可知他是被就坐的对象，观看的主语，故前文用过去分词，下文用现在分词。选B。
