Having the right hand and arm being cripped by a sniper'sbullet during the First World War, Horace Pippin, a black American painter, worked by holding the brush in his right hand and guilding its movements with his left.
E, His right hand and arm cripped by a sniper's bullet during the First World War.
之所以有having ...cripped估计他想考独立主格的完成时态,因为独立主格中,如果分词发生的时间先于主句动词发生时间,常用现在分词完成时态表示,但这里用错了,应该是His right hand and arm (having)cripped by a sniper's bullet during the First World War.正确答案之所以又省略了having,我觉得是因为后面的时间状语 First World War,使先于主句发生的这个事件可以清晰表达。
