Mary often stays up, reviewing her lessons, books___ all over the desk.A.spreadingB.spreadC.are spreadingD.to spread
网友回答
B解析试题分析：句意：玛丽经常熬夜复习功课，书摊了一桌子。这里整句话没有连词，reviewing是非谓语动词，它与Mary是主动关系；books spread all over the desk这是独立主格结构，books与spread之间是被动关系，故spread是过去分词；故选B。考点：考查独立主格结构的用法。
点评：本题较难。独立主格结构是高中的难点，近几年考得次数较少，需要考生有分析理解复杂的句子结构的能力，还必须能够理解句意。即学即练：He was listening attentively in class, his eyes ____on the blackboard.A. fixing B. fixed C. are fixing D. to fixed解析：B。句意：他上课专心听讲，眼睛紧盯着黑板。
