32. It took them much trouble to take the old picture, ________ there for several centuries, down from the wall.
A. hanging B. being hung C. hung D. having hung
【答案】A。解析：考查非谓语。句意：把那幅挂在墙上几个世纪的旧画从墙上搬下来给他们带来很大麻烦。根据分析句子有谓语took，所以空处用非谓语形式。且空处作后置定语修饰picture，当hang表示“悬挂”，如果被悬挂的东西是非生命体的物体，所以hang是不及物动词，无被动形式。根据分析这里修饰的是picture，是非生命体，所以这里用现在分词hanging作后置定语。故选A。
