I won't.(抱歉,我不会再做了。)Language points祈使句: — Be careful!用法:提醒对方小心、注意安全,可放在具体提醒句前,加强语气,口语化极强。原文例句:Be careful, Yangyang!(洋洋,小心点!)使用场景:看到对方有危险行为时,可单独说,也可接后续提醒句。Language points肯定祈使句—— 动词原形 + 其他.用法:提醒对方要做某事,无主语,动词原形开头,用于给出纠正后的正确行为,常接在否定提醒后。原文例句:① Walk slowly and keep to the right, please.(请慢慢走,靠右行。)② I will walk.(我会慢慢走的。)(学生回应中的简化指引)特点:可加please放在句尾,让语气更礼貌,标点用逗号隔开。Language points祈使句回应 —— All right, ...

(禁止玩玩具!)Language pointsLanguage pointsNo + 动名词(doing). 核心翻译:禁止做……!/ 不许……!用法:禁止具体的某个动作,动词变doing 形式①一般动词直接加 ing,如 run→running;②以 e 结尾去 e 加 ing,如 write→writing)。No running! (禁止奔跑!) No talking!
