________ made them much disappointed.A. His not coming back B. Not his comin
Five people were reported ________ in the accident.
A. to be killed B. to kill C. killed D. to have been killed
为什么选D不选A

His not coming back made them much disappointed.
not coming back 相当于一个名词,接在his后面.
Five people were reported to have been killed in the accident.
被杀害（kill）发生在报道（report）之前,应该用过去完成时,
但是因为被动后面要跟to do,所以had变成了have.这可能是蒙蔽你的一点.
