问题描述：
You ______to the meeting tomorrow if you have something important to do
A.neednt to come
B.dont need come
C.dont need coming
D.neednt come
答案为什么选D 求理解
答
need既可以做实义动词又可以做情态动词。一种need to do sth.否定do not need to do sth .情态动词时need do sth.否定need not do sth.往里面套只有d 正确。此外，need doing sth.对于need to be done 需要被做。。。主动表被动
答
因为这是条件状语从句,从句用一般现在时,主句不是将来时,就是用情态动词
A 自身否定,认为是情态动词,可是加了to ,就错
B 用了一般现在时,错,need 后面没加to ,错上加错
C 用了一般现在时,错,need coming 表被动,错上加错
D 自身否定,正是情态动词
