There seems something wrong with my camera.It needs______.答案为什么选repairing?
A ,being repairing B,repairing C,to repair D,repaired.请问选B的原因是什么?

need doing=need to be done 主动表被动 意为:需要(被)。。。

答案是B
It needs REPAIRING (主表被结构)
==It needs TO BE REPAIRED (被动语态结构)
请注意,这里的need==want / require --------它们在语法功用上相同.
