You ( )to the meeting this afternoon if you have something important to do.
A needn't to come B don'tneed come C don't need coming D needn't come 为什么不能选A
答案:D needn't come
1.need做情态动词时,否定式是needn't do (needn't+原形动词)
.2.need做行为动词用时,否定式是 don't(doesn't/didn't……) need to do (助动词的否定式+ need to do )
不管它是作为情态动词还是行为动词,其否定式都不会是 needn't to do ,所以A needn't to come 是不存在的
