I’m OK. 解析：日常交际语，用于他人发生意外 / 摔倒后，询问身体状况，答语固定，简单易记。 拓展：若受伤可答：No, I'm not OK. 我不舒服。 Language points 表建议/劝告：You should + 动词原形 + 其他. （表建议 / 劝告） 原文句：You should stop at the red light! 解析：情态动词 should 表 “应该”，用于对他人提交通规则 / 安全方面的劝告，语气委婉；后必须接动词原形，否定式：shouldn't（should not）+ 原形。 例句：You should walk on the sidewalk. 你应该在人行道上走。 Language points It's + 形容词 + to do sth. （形式主语句型） 原文句：It's dangerous to ride so fast. 解析：小学核心重点句型，It 是形式主语，真正的主语是后面的to do 不定式，用于表达 “做某事是…… 的”；dangerous 是形容词，表 “危险的”。 替换形容词：It's safe to stop at the red light. 红灯停是安全的。 It's important to obey traffic rules. 遵守交通规则很重要。 Language points I won't do that again. （表 “不再做某事”） 原文句：I see. I won't do that again. 解析：won't=will not，是 will 的否定式，后接动词原形，用于犯错后承诺 “将来不再做某事”，贴合交通规则认错场景。 例句：I won't run in the street again. 我不会再在街上跑了。 Language points 语法点 1：现在进行时（表 “正在做”） 核心结构：am/is/are + 动词的 - ing 形式 原文例子：The monkeys are riding bikes.（复数主语 + are+doing） 动词 - ing 变化规则（小学基础）： 直接加 ing：look→looking 去 e 加 ing：ride→riding /stop→stopping 双写末尾字母加 ing：run→running /fall→falling（本单元暂记即可） 关键：看到 “正在、此刻” 等词，或动作正在发生，用现在进行时。 Language points 语法点 2：一般现在时的否定句+动词三单 （1）动词三单（主语为 he/she/it/ 单数名词） 原文例子：he puts / he looks / he runs / he falls 简单规则：一般动词直接加 s（put→puts）； 以 s/x/sh/ch/o 结尾加 es（go→goes）； 辅音 + y 结尾变 y 为 i 加 es（fly→flies）。 Language points 三单（he/she/it） doesn't + 动词原形 He doesn't stop at the red light. 非三单（I/we/you/they） don't + 动词原形 We don't ride fast in the street. 易错点：助动词 doesn't/don't 后，动词必须变回原形，不能用三单！ Language points 频度副词sometimes的用法 含义：有时候（频率较低） 位置：① 句首，后加逗号：Sometimes, he looks at people around him. ② 句中（be 动词后 / 实义动词前）：He sometimes rides fast. 同类词：often（经常）/usually（通常），用法和 sometimes 一致。 Language points Lesson 8 Stop at the Red Light!
