You___to the meeting this afternoon if you have something important to do.

问题描述:

You___to the meeting this afternoon if you have something important to do.
A:needn't to come B:don't need come C:don't need coming D:needn't come为什么选D不选A啊?
可是不是NEED TO DO STH。

要是用needn't的话 说明它是情态动词(只有情态动词可以这么缩写),就可以直接加动词原形,而不接to拉,所以A不对.
