【题目】Floyd, a 46-year-old black man, died hopelessly, ________ against the floor by a policeman for nine minutes, which gave rise to protests throughout the USA
A.having pinnedB.to be pinningC.pinningD.having been pinned
在线课程【答案】D
【解析】
考查非谓语动词。句意：弗洛伊德，一位46岁的黑人，被一名警察按压在地上9分钟后，无助地死去，这引发了全美的抗议行动。分析句子结构可知，动词pin在句中作定语，和主语Floyd是被动关系，而且动词pin动作的发生早于谓语动词die，需用having been done结构。故选D。
