Unfortunately he fell over some bricks ________ lying on the ground.

Unfortunately he fell over some bricks ________ lying on the ground.

A.left

B.having left

C.leaving

D.to leave

答案及解析： B

解析：

分析句子结构可以知道some bricks后面应该是个定语，leave后面可以跟复合宾语，leave sb./ sth. doing表示“使某人／某物保持某种动作／状态”，本题中的some bricks是leave的宾语，因此过去分词作定语表示被动，而且用完成时态来表示动作发生在fell over这一动作之前，having left = which have been left．
