问题补充：

You to meeting this afternoon if you have something important to do.

A. needn’t to come

B. don’t need come

C. don’t need comimg

D. needn’t come

答案：

A. needn’t to come

B. don’t need come

C. don’t need comimg

(答案→)D. needn’t come

解析：need可以作为情态动词，否定形式为needn’t，后跟动词原形，need也可以作为一般的实意动词，表示需要做某事结构为need to do，否定形式在动词前加don’t，故本题选D。
