You _____ to the meeting tonight if you have something important to do.
a .needn't to come B.don't need to come C.don't need coming D.needn't come
这里似乎B.D都对,但哪个更好些?我们老师说两个都可以,但我始终觉得只有D可以

BD 都正确.这里考察了need 的用法：
need 有两个词性：实义动词和情态动词
当实义动词讲时,其后跟不定式 to do . 否定句借助于助动词do
当情态动词讲时,符合情态动词的用法,即其后跟动词原形.否定句在其后加not
