there is no need ___ it till midnight.you only need ____it and watch it tomorrow.
A.to watch record
B.to watch to record
C.watch to record
D.watching recording
我知道答案就在A或B里面选.只是无法确定后面的need是情态动词 need do
还是固定结构 need to do?
求高手指教.

答案

选择A 既然你说无法确定后面的前面我就不说了
这里判断是否是情态动词的依据是and,and引导并列句,前后的谓语形式应该是一样的,and后面watch并没有加动词不定式,说明need这里是情态动词,前后统一,所以选择A
