Binbin: Oh no! It's flu season now. (天呐!现在正是流感高发期。)
Miss White: That's right. How can we all stay healthy? (没错。我们要怎样才能保持健康呢?)

【核心词组积累】
· has a cold 感冒 (表示生病状态,主语单三用 has)
· stay at home 待在家里
· flu season 流感季节 / 流感高发期
· stay healthy 保持健康 (stay 在这里是系动词,后接形容词 healthy)
· eat healthy food 吃健康的食物 (healthy 是形容词修饰名词 food)
· get enough sleep / drink enough water 保证充足的睡眠 / 喝足量的水 (enough 修饰不可数名词时放其前面)
· see a doctor 看医生
【核心句型精讲与真题演练】
📌 句型 1:表达健康建议的核心情态动词(We should...)
· 核心结构: 主语 + should + 动词原形 (+ 其他). (某人应该做某事。)
· 💡 避坑提示: should 是情态动词,表示“应该”。它没有任何人称和数的变化(无论主语是 I, he 还是 we,都用 should),且后面必须紧跟动词原形。其否定形式为 should not /

(一) 单项选择
( ) 1. It's late. We should _______ to bed right now.
A. go B. goes C. going
( ) 2. He is too fat. He _______ eat too much sweet food.
A. should B. shouldn't C. can
📌 句型 2:修饰词 enough 的特殊位置(enough water / sleep)
· 核心结构: enough + 名词 (足够的名词) | 形容词/副词 + enough (足够地……)
· 💡 避坑提示: 课文中的 enough water 和 enough sleep 展示了其最基本的用法:
**enough 修饰名词时,必须放在名词的前面**。但在高年级真题中经常会对比考查修饰形容词时要后置(如 *old enough* 足够大)。

( ) 1. To stay healthy, we should drink _______ every day.
A. water enough B. enough water C. an enough water
(2) 连词成句

📌 句型 3:条件状语从句的初步运用(If you don't feel well, you should...)
· 核心结构: If + 句子, 主语 + should / 动词原形... (如果……,就……)
· 💡 避坑提示: If 引导的是条件状语从句,意为“如果”。注意 `feel well` 中的 **well** 在这里是形容词,专指“身体好、感觉舒服”。如果 if 从句放在句首,从句结束时**一定要加逗号
**。
