Need 能不能做疑问句的句首
Need you play the piano at such a late hour?错在什么地方

need 有两个作用,一个是情态动词,另一个是及物动词.
翻译成“必要”的时候是情态动词,和其它的情态动词一样,后面接动词原形,可以帮助构成疑问和否定;如 you needn't tell me that.
翻译成“需要”时是及物动词,后面要接宾语.
如 I need your help.
如果说你举的例子有问题,可能是语义方面,而不是语法方面.
must you play the piano at such a late hour?似乎更合理一些:你非得这么晚弹琴吗?
浅见,仅供参考.这是原题:John,look at the time._____you paly the piano at such a later hour?A.Must B.Can CMay D.Need.选A约翰,看看几点了?你非得这么晚弹钢琴吗?
