【人教PEP版六年级上册】 Unit 6 Energy, nature and us 核心语法专项训练 单元语法小结 一、情态动词must / mustn’t 1. 用法：must+动词原形表示必须遵守的环保、节约能源硬性规定；mustn’t+动词原形表示禁止破坏自然、浪费能源的行为，语气强硬，用于规章制度、行为准则。 2. 语法特征：无人称、数的变化，所有人称直接使用must/mustn’t。 3. 句式变换 一般疑问句：Must + 主语 + 动词原形？ 肯定回答：Yes, 主语 + must. 否定回答：No, 主语 + needn’t / don’t have to（不能用mustn’t回答） 例句：We must save electricity.
