What’s the matter I have a really bad toothache. You should see the dentist and get an X-ray. You could eat some soft food for now.

表建议的情态动词：should（表 “应该”）、shouldn’t（表 “不应该”）、could（表 “可以”），用于给他人提供建议。
Let’s learn
1. should / shouldn’t
用法：最常用的提建议表达，语气较为温和、客观，强调 “应该 / 不应该” 做某事，带有一定的合理性或劝诫意味。
例句：
You should drink more water if you have a sore throat.
You shouldn’t stay up late before an exam.
Let’s learn
2. could
用法：语气更委婉、试探，提出的建议通常是可选的、供对方参考的，不带有强制感。
例句：
You could ask your teacher for help with your homework.
You could try this new coffee shop near the school.
第一步：通读整段短文，理解主题。
第二步：根据句子的语境判断是 “建议做某事”（用 should/could）还是 “建议不做某事”（用 shouldn’t）。
第三步：如果建议语气较委婉，用 could；如果建议语气较强、强调必要性，用 should；如果是禁止性建议，用 shouldn’t。
第四步：填完后再通读一遍，检查建议是否符合逻辑。

Read the sentences. Circle the reflexive pronouns.
What’s wrong I ate too much last night. Now my stomach aches. You shouldn’t eat so much next time.
What’s the matter I have a really bad toothache. You should see the dentist and get an X-ray. You could eat some soft food for now.

反身代词是英语中表达“……自己；本身”含义的一类代词。
Let’s learn
反身代词的形式
数 第一人称 第二人称 第三人称
单数
复数
myself
ourselves
yourself
yourselves
himself
themselves
herself
itself
反身代词是在第一人称、第二人称形容词性物主代词，第三人称人称代词宾格形式的词尾加-self或-selves组成。
Let’s learn
反身代词的用法
1. 作宾语：当动作的承受者是主语自身时，必须用反身代词。
例：He cut himself while cooking.
2. 表强调：用于强调主语“亲自”完成动作。
例：I made this cake myself.
3. 作表语：用于描述人的状态或身份。
例：Just be yourself in the interview.
【注意】反身代词不能单独作主语；且需与被指代的人称在人称和数上保持一致。
第一步：先读全句，确定句子的主语是谁（比如 the girl、you、we）。
第二步：对应主语，找到正确的反身代词形式（例如 I → myself, you → yourself/yourselves）。
第三步：检查反身代词是否在句中表达 “某人自己” 的含义，确保逻辑通顺。

选情境：从课本提示或自己想的健康问题里选一个，比如胃痛、摔伤、喉咙痛等。
二、角色任务
建议者先猜测病因，然后患者描述自己的症状或受伤原因，建议者再用 should/shouldn’t/could 给出具体建议。（其他小组可补充更多建议。）
本课提建议的核心情态动词有哪些？
反身代词的核心作用是什么？
情态动词口诀：should 表应该，否定直接加 not；could 更委婉，建议参考超好用。
反身代词提醒：主宾一致才能用，I 变 myself，you 变 yourself，单复数要记清。
（should/shouldn’t/could）
（指代主语，表 “某人自己”）
