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

A. needn’t to come

B. don’t need to come

C. needn’t coming

D. didn’t need coming

答案：

A. needn’t to come

(答案→)B. don’t need to come

C. needn’t coming

D. didn’t need coming

解析：句意：如果你有重要的事情要做，你不必参见今天下午的会议了。结合语境可知本句中need为行为动词，需要。故其否定形式要借助于助动词。结合语境可知本句描述的是客观性动作，故用一般现在时态，主语you是第二人称，故助动词用do，选B。
