网友回答

A. Not finishing
B. Not finished
C. Having not finished
(答案→)D. Not having finished
解析：句意：这个男孩没有完成他的项目，不得不熬夜了。句中考察非谓语动词，finish 这个动词的逻辑主语是the boy是主动关系，not finish没有完成这个动作发生在主句谓语动词had to 之前，故用完成时的形式。值得注意的是否定形式的完成时要用Not having finished的形式，而没有Having not finished的形式，但是有Having never finished的形式。故选D.
