问题描述:
need的过去式还是need吗
李昆仑回答:
是
need做情态动词时没有时态的变化,过去式也是need.后面接动词原形.如:
Ineedwritealetteryesterday.
Needheansweritthen?
Yes,heneed.
No,heneedn't.
情态动词need表示对过去的推测时常和现在完成时连用.如:
Youneedn'thavehurried.你当时不必这么匆忙.
need做实义动词(行为动词)时,过去式是needed.后面接todo.如:
Ineededtowritealetteryesterday.
Didheneedtoansweritthen?
Yes,hedid.
No,hedidn't.
