2024年新教材七年级下册英语人教版 Unit 2 No Rules, No Order 易错专题专练+解析
本单元主题是"Rules"，学生需要掌握有关校规、家规的英语表达，熟练运用祈使句（肯定与否定）、情态动词 must / have to / can 表示规则与许可，以及方位介词描述位置。单元常见词汇包括 rule, hallway, uniform, litter, polite, absent, belt, noise 等；核心句型包括 Don't run in the hallways. What rules do you have? We must/have to... 等。
本资料重点训练以下易错内容：
• 祈使句的否定形式（Don't vs Doesn't）
• must 与 have to 的辨析（主观义务 vs 客观要求）
• wear 与 put on 的区别
• be late for 与 arrive late for 的用法
• 情态动词 can 表示许可的用法
• 介词 in, on, at 表示地点的区别
• 句型转换（对划线部分提问、同义句转换）
易错点一：祈使句的否定形式
本单元重点学习祈使句。学生常犯的错误是在祈使句前加主语或助动词，例如错误地使用 Doesn't run，而正确的否定形式应为 Don't + 动词原形。

A. Don't B. Don't be C. Not be D. Doesn't be
易错题2
______ in the hallway. You may fall down.
A. Don't running B. Not run C. Don't run D. Not running
易错点二：must 与 have to 的辨析
两者都表示"必须"，但 must 强调说话人的主观看法或法律义务；have to 强调由于客观环境或规则迫使"不得不"。此外，must 提问的否定回答用 needn't 或 don't have to。

A. mustn't B. can't C. needn't D. haven't

易错点三：wear, put on, dress 的区别
• wear：穿着（状态）
• put on：穿上（动作）
• dress：给……穿衣（宾语是人）
学生常混淆它们的用法。

易错题6

A. wear B. put on C. dress D. in

两者意思相近，但 be late for 更为常用。学生容易遗漏 be 动词。
易错题7

A. arrive late for B. is late for C. arrives late for D. be late for
