Whenever I enter the library, I see him at the back of the library reading.A. sit B. sat C. seating

【题目】Whenever I enter the library, I see him at the back of the library reading.

A. sit B. sat C. seating D. seated

【答案】D

【解析】

试题分析：考查非谓语动词。本句考查非谓语动词担当宾语补足语。非谓语动词担当宾语补足语时，如果跟在see这类词之后则存在三种情况，分别是：see sb. doing，指看到某人正在做；see sb. do，指看到某人做某事；see…done，指看到…被…。需要注意的是，seat这个词是及物动词，在表示某人坐着时，用be seated，故本句选择D，相当于see him sitting。
