{01}________ every student aware of the importance of study, they would study efficiently. A.Were B.Should C.May D.Had 解析：考查省略及倒装，此题是表示与将来相反的虚拟语气，省略if，should 前提，正常语序为If every studen should aware of the importance of study，句意：如果每一个学生意识到学习的重要性，他们就会有效的学习。所以选B。
本题选B。
{02}You__      to the meeting this afternoon if you have something important to do . A.needn’t to come B.don’t need come C.don’t need coming D.needn’t come 解析：考查need的用法：need做情态动词，否定是needn’t后面接动词原形，need是实意动词，否定要加助动词后面接to do，选D。句意是：如果你有重要的事做下午就不必开会。选D。
本题选D。
